Description

  The present invention relates to a heating control device, a heating cooking system, and a program.

  The gas stove is provided with an operation unit that is operated when adjusting the heating power of the burner, and the user of the gas stove (hereinafter referred to as “user”) adjusts the heating power of the burner by operating the operation unit. To do.

  By the way, if the operation amount of the operation unit is wrong, a thermal power larger than the thermal power intended by the user may be obtained. Moreover, when the size of the main body of a cooking utensil such as a pan or a frying pan is smaller than the size of the virtues on the gas stove, a flame may overflow around the cooking utensils when the cooking utensils are placed on the virtues. In such a state, if the user's hand or clothing approaches the flame, the user may be ignited. Moreover, even if there is no possibility that the user will ignite, excessive thermal power will waste gas. Therefore, various techniques have been proposed for adjusting the heating power according to the situation even if the operation unit is not operated by the user.

  For example, Patent Document 1 discloses a technique for reducing the burner's thermal power on the condition that a human sensor that is an infrared sensor detects that a human hand has approached the five victories on the stove. Patent Document 1 also discloses a technique for reducing the burning power of a burner on the condition that an increase in the surface temperature of clothing worn by a person is detected by a human sensor.

  Patent Document 2 discloses a technique for reducing the burning power of a burner when the time when white smoke generated before the oil spontaneously ignites is continuously detected by an optical sensor reaches a set time.

  In Patent Document 3, a change in the amount of flame is detected by an ultraviolet sensor, and an alarm is output when it is determined that an object (human body or clothes) is in close proximity to the flame based on the detection result of the ultraviolet sensor. The technology is disclosed.

  Patent Document 4 discloses a technique in which only a flame overflowing from the periphery of a cooking utensil is detected by an ultraviolet sensor, and the heating power is adjusted according to the size of the cooking utensil based on the detection result.

  In addition, a technique for specifying the position of a user or a cooking utensil is also known. For example, Patent Document 5 discloses a technique in which a cooking process of a cook is photographed with a camera and a movement path of a cooking utensil possessed by the cook is detected based on a photographed image.

JP 2004-293953 A JP 2000-274664 A JP2013-190190A JP 2011-106729 A Patent No. 3794692

  However, none of the techniques described in each of the above-mentioned patent documents has a temperature measured by a so-called pan bottom sensor, although the cooking area of the cooking utensil in a state of receiving a heating force is not in a state of inducing ignition.

The cooking utensil image area refers to an image showing cooking utensils such as a frying pan and a pan.

  Whether or not the cooking utensil image region exists in the processing target region is determined based on a comparison between the reference image indicated by the reference image information and the processing target region. That is, the CPU 60 determines whether or not the burner image area indicating the burner 24 exists in the processing target area based on the difference between the reference image and the processing target area, so that the cooking utensil image area exists in the processing target area. It is determined whether or not. The presence of the burner image area in the processing target area means that the cooking utensil is not placed on the virtues 28 in the rectangular area in plan view corresponding to the processing target area. That the burner image area does not exist in the processing target area means that the cooking utensil is placed on the five virtues 28 in the rectangular area in plan view corresponding to the processing target area.

  In step 156, if there is a cooking utensil image region in the processing target region, the determination is affirmed, and the process proceeds to step 158. If it is determined in step 156 that there is no cooking utensil image area in the processing target area, the determination is negative, and the process proceeds to step 170.

  In step 158, the CPU 60 determines whether or not the processing target area is an excessive heat state image area. The excessive thermal power state image region refers to an image region indicating an excessive thermal power state with respect to the stove upper region 52.

  The overheated state image region is roughly divided into, for example, an overhang flame image region, an overheated image region, and a cooking product ignition image region. In this step 158, the processing target region is an overrun flame image region, an overheated image region, It is determined whether or not it is at least one of the cooking object ignition image areas.

  When the CPU 60 determines whether or not the processing target area is an excessive heat state image area, first, the processing target area is classified into a cooking image area indicating a cooking area and a non-cooking image area indicating a non-cooking area. . The cooking image region and the non-cooking image region are classified based on the difference between the processing target region and the reference image corresponding to the processing target region. That is, based on the difference between the processing target region and the reference image, a circular region or a rectangular region having an area equal to or larger than a predetermined area in the processing target region is detected as a cooking image region, and other than the cooking image region in the comparison target image region Are detected as non-cooked image areas.

  In the example shown in FIG. 10, a cooking area 130A and a non-cooking area 130B are shown. The cooking area 130 </ b> A is a main body area of the frying pan 130 in the rectangular area 102 in plan view. The non-cooking area 130B is an area other than the cooking area 130A in the rectangular area 102 in plan view. In this case, based on the difference between the processing target area indicating the planar rectangular area 102 and the second reference image, an image area indicating a circular area having an area equal to or larger than a predetermined area is detected as a cooking image area indicating the cooking area 130A. . Then, an image area other than the cooking area 130A in the processing target area showing the rectangular area 102 in plan view is detected as a non-cooking image area showing the non-cooking area 130B.

  The overhang flame image area is a state in which the flame protrudes from the outer peripheral edge of the cooking utensil in a size larger than a predetermined size (in other words, a size larger than a predetermined size around the cooking utensil). This is an image area showing an overflow state). Whether or not the processing target region is a protruding flame image region is determined based on a comparison result obtained by comparing the processing target region with a reference image corresponding to the processing target region.

  When determining whether or not the processing target area is a protruding flame image area, the CPU 60 first detects, from the non-cooked image area, a first flame image area indicating a flame protruding from the outer peripheral edge of the cooking utensil. That is, a high-brightness image region having a difference absolute value that is greater than or equal to the first predetermined value with respect to the first reference luminance (for example, luminance predetermined as representative luminance of the top plate 22) in the non-cooked image region. It is detected as the first flame image area. The first predetermined value refers to, for example, a value corresponding to an absolute value of a difference between the luminance predetermined as the representative luminance of the lightest flame among the flames of the burner 24 and the first reference luminance.

  Then, the CPU 60 determines whether or not the processing target area is a protruding flame image area by determining whether or not the area (number of pixels) of the first flame image area is equal to or larger than the first predetermined area (first predetermined pixel number). Determine. That is, when the area of the first flame image region is equal to or larger than the first predetermined area, it is determined that the processing target region is a protruding flame image region, and when the area of the first flame image region is less than the first predetermined area, the processing target It is determined that the area is not a protruding flame image area.

  The overheated image area is an image area that indicates an excessive state of heating of the food. As an example of the overheated image area, as shown in FIG. 11, an image area showing the planar rectangular area 102 when white smoke of a predetermined amount or more rises from the frying pan 130 placed in the planar rectangular area 102. Can be mentioned.

  The CPU 60 determines whether the area to be processed is determined by determining whether or not the area of the white area in the area to be processed (for example, the number of pixels indicating white) is equal to or greater than a second predetermined area (second predetermined number of pixels). It is determined whether it is an overheated image area. That is, when the area of the white region in the processing target region is equal to or larger than the second predetermined area, it is determined that the processing target region is an overheated image region. For example, this means that a predetermined amount or more of white smoke has risen from the frying pan 130 shown in FIG. When the area of the white region in the processing target region is less than the second predetermined area, it is determined that the processing target region is not an overheated image region.

  In addition, although white smoke was illustrated here, it is not restricted to this, You may be smoke other than white smoke (for example, black smoke). In this case, it is determined whether or not the area to be processed is an overheated image area by determining whether or not the area of the smoke color area is equal to or larger than the second predetermined area.

  The cooked product ignition image area is an image area showing a state in which the cooked product in the cooking utensil is ignited. As an example of the cooked product ignition image area, as shown in FIG. 12, an image area showing the planar rectangular area 102 when the cooking area 130 </ b> A of the frying pan 130 placed in the planar rectangular area 102 is ignited. .

  The CPU 60 determines whether or not the processing target region is the cooked product ignition image region by determining whether or not the second flame image region indicating the flame ignited by the cooked product exists in the cooked image region. The second flame image area is a high-luminance image area having a luminance whose absolute value of difference from the second reference luminance in the cooking image area is equal to or greater than a second predetermined value. The second reference luminance refers to a luminance that is determined in advance as a general luminance of a food that is not ignited, for example. The second predetermined value refers to, for example, a value corresponding to the absolute difference between the luminance predetermined as the representative luminance of the lightest flame among the flames on the food and the second reference luminance. .

  In step 158, if the processing target area is an overheat state image area, the determination is affirmed and the process proceeds to step 160. If it is determined in step 158 that the processing target area is not an excessive heat state image area, the determination is negative and the process proceeds to step 176.

  In step 160, the CPU 60 adds 1 to the count value of the counter corresponding to the processing target area among the counters (not shown) provided for each comparison target image area, and then proceeds to step 162.

  In step 162, the CPU 60 determines whether or not the count value of the counter corresponding to the processing target area exceeds a first threshold (for example, 10). In step 162, when the count value of the counter corresponding to the processing target area exceeds the first threshold value, the determination is affirmed, and the process proceeds to step 164. In step 162, when the count value of the counter corresponding to the processing target area is equal to or smaller than the first threshold value, the determination is negative, and the process proceeds to step 170.

  If the determination in step 162 is affirmative, it means that the overheated state image region exists in each of the photographed images obtained by photographing a plurality of times. Excessive thermal power state image areas indicate that there are excessive thermal power state image areas at the same position in each captured image. Excessive thermal power state image regions exist at the same position in the captured image means that, for example, all of the comparison target image regions indicating the rectangular region 102 in plan view in each captured image captured multiple times are in excessive thermal power state. Indicates an image area.

  As described above, when the determination in step 162 is affirmed, it means that the captured image is a thermal power excessive state image that indicates an excessive thermal power state with respect to the stove top region 52.

  In step 164, the CPU 60 controls the control target burner as thermal power reduction instruction information for instructing to reduce the thermal power of the burner 24 (hereinafter referred to as “control target burner”) in the rectangular region in plan view corresponding to the processing target region. The thermal power reduction instruction information including the burner identification information that can identify the power is generated. Then, the generated thermal power reduction instruction information is transmitted to the stove 12 via the WiFi communication unit 80, and then the process proceeds to step 166.

  In step 166, the CPU 60 resets the count value of the counter corresponding to the processing target area to an initial set value (for example, 0), and then proceeds to step 168.

  In step 168, the CPU 60 turns on a temperature decrease waiting flag indicating that it is waiting for a temperature decrease in the cooking area, and then proceeds to step 170.

  In step 170, the CPU 60 determines whether or not a condition for terminating the first control process (first control termination condition) is satisfied. As an example of the first control end condition, a condition that an instruction signal for instructing the end of the first control process is input to the photographing / control apparatus 14 or after the first control process is started. The condition that predetermined time (for example, 1 hour) passed is mentioned.

  If the first control end condition is not satisfied in step 170, the determination is negative and the routine proceeds to step 172. In step 170, if the first control end condition is satisfied, the determination is affirmed and the first control process is ended.

  In step 172, the CPU 60 determines whether or not there is an unprocessed comparison target image area. Here, the unprocessed comparison target image region refers to a comparison target image region that is not set as a processing target region in step 154. If there is no unprocessed comparison target image area in step 172, the determination is affirmed and the process proceeds to step 174. If it is determined in step 172 that there is an unprocessed comparison target image area, the determination is negative, and the process proceeds to step 154.

  In step 174, the CPU 60 determines whether image information is newly stored in the image storage unit 78. In step 174, if new image information is stored in the image storage unit 78, the determination is affirmed and the process proceeds to step 150. If it is determined in step 174 that image information is not newly stored in the image storage unit 78, the determination is negative and the process proceeds to step 170.

  In step 176, the CPU 60 determines whether or not the count value of the counter corresponding to the processing target area is 1 or more. In step 176, when the count value of the counter is 1 or more, the determination is affirmed, and the routine proceeds to step 178. In step 176, if the count value of the counter is less than 1 (in the case of “0”), the determination is negative and the routine proceeds to step 180.

  In step 178, the CPU 60 resets the count value of the counter, and then proceeds to step 180.

  In step 180, the CPU 60 determines whether or not the temperature decrease waiting flag is turned on. In step 180, if the temperature decrease waiting flag is turned on, the determination is affirmative and the routine proceeds to step 182. In step 180, if the temperature decrease waiting flag is not turned on (if turned off), the determination is negative, and the routine proceeds to step 188 shown in FIG.

  In step 182, the CPU 60 determines whether or not the processing target area is a temperature decrease state image area. The temperature decrease state image region refers to an image region indicating the temperature decrease state of the cooking region.

  When the thermal power reduction instruction information is transmitted to the stove 12 by the processes of steps 164, 190, and 204, the CPU 100 causes the thermal power of the burner to be controlled to decrease in step 252 of the third control process (see FIG. 15) described later. The electromagnetic valve driving unit 116 is controlled. Thereby, when the temperature of a cooking area falls, the aspect of a cooking area will differ greatly from the aspect of a cooking area when a thermal power is an excessive state. For example, the amount of bubbles and the amount of white smoke are greatly reduced.

  Therefore, in step 182, the CPU 60 determines whether or not the processing target area is a temperature decrease state image area based on the difference between the processing target area and the latest overheated state image area acquired previously. .

  That is, the absolute difference value for each pixel between the first specific area of the latest excessive heat state image area and the second specific area of the processing target area is calculated, and the sum of the calculated absolute differences is greater than or equal to the third predetermined value. In this case, it is determined that the processing target area is a temperature decrease state image area. When the sum of the absolute differences is less than the third predetermined value, it is determined that the processing target area is not the temperature-decreasing state image area. The first specific area refers to, for example, a cooking image area in the latest excessive heat state image area, and the second specific area refers to, for example, a position corresponding to the position of the first specific area in the processing target area. The image area (here, the cooked image area as an example).

  If it is determined in step 182 that the processing target area is a temperature decrease state image area, the determination is affirmed, and the process proceeds to step 184. If it is determined in step 182 that the processing target area is not the temperature-lowering state image area, the determination is negative and the process proceeds to step 188 shown in FIG.

  In step 184, the CPU 60 includes thermal power increase instruction information including the same burner identification information as the thermal power increase instruction information generated in step 164 as the thermal power increase instruction information instructing an increase in the thermal power of the control target burner. Is generated. Then, the generated thermal power increase instruction information is transmitted to the stove 12 via the WiFi communication unit 80, and then the process proceeds to step 186.

  In step 186, the CPU 60 turns off the temperature decrease waiting flag, and then proceeds to step 170.

  In step 188 shown in FIG. 9, the CPU 60 determines whether or not the cooking image area in the processing target area is the ignition attraction image area. The ignition attraction image area refers to an image area indicating a cooking area that is likely to ignite when heated.

  Whether or not the cooking image area is the ignition attraction image area is determined by comparing the plurality of ignition attraction images indicated by each of the ignition attraction image information stored in the ignition attraction image DB 92 and the cooking image area in the processing target area. It is determined based on. That is, when there is an ignition attraction image whose degree of coincidence with the cooking image area in the processing target area is a second threshold (for example, 70%) or more among the plurality of ignition attraction images, the cooking image in the processing target area It is determined that the area is an ignition attraction image area. If there is no ignition attraction image whose degree of coincidence with the cooking image area in the processing target area is greater than or equal to the second threshold among the plurality of ignition attraction images, the cooking image area in the processing target area is not the ignition attraction image area Determined.

  In step 188, if the cooking image area in the processing target area is the ignition attraction image area, the determination is affirmed, and the routine proceeds to step 170. If it is determined in step 188 that the cooking image area in the processing target area is not the ignition attraction image area, the determination is negative and the process proceeds to step 192.

  In step 192, the CPU 60 generates non-decreasing instruction information including burner specifying information as non-decreasing instruction information for instructing not to decrease the heating power of the burner to be controlled. Then, the generated non-decreasing instruction information is transmitted to the stove 12 via the WiFi communication unit 80, and then the process proceeds to step 170 shown in FIG.

  Next, the second control process performed by the photographing / control device 14 when the CPU 60 executes the second control program 85 when the main power of the photographing / control device 14 is turned on will be described with reference to FIG. To do.

  In the second control process shown in FIG. 13, first, in step 200, the CPU 60 acquires image information for one frame from the image storage unit 78, and then proceeds to step 202.

  In step 202, the CPU 60 determines whether or not the captured image for one frame indicated by the image information acquired in step 200 is an ignition trigger image. As shown in FIG. 14 as an example, the ignition attraction image refers to an image showing an upper stove area 52 in a state where a hand 136 (an example of a human body) taken out of clothing 134 is present in the ignition attraction area 132. . The ignition attraction area 132 refers to an area that is predetermined as an area in which ignition for at least one of the clothes 134 and the hand 136 is attracted. In the example shown in FIG. 14, the ignition attraction area 132 is an upper half area when the stove upper area 52 is viewed in plan (only the rectangular area 100 in plan view among the rectangular areas 100, 102, and 104 in plan view shown in FIG. 5). Is a region within a horizontally long rectangular frame).

  The CPU 60 determines whether or not a hand image area indicating the hand 136 exists in an image area corresponding to the position of the ignition attraction area 132 in the captured image (hereinafter, referred to as “focused image area”). It is determined whether the captured image is an ignition attraction image. Whether or not it is a hand image area is determined by determining whether or not there is an image area whose degree of coincidence with the sample image is equal to or greater than the third threshold in the image area of interest. Determine whether. The hand sample image is a sample image showing a hand, and a plurality of hand sample images having different contents are stored in a database in the secondary storage unit 64. Therefore, for example, when there is an image area whose degree of coincidence with any of the sample images is 70% or more in the image area of interest, the captured image is determined to be an ignition attraction image.

  In addition, although the case where the CPU 60 determines whether or not the captured image is an ignition attraction image by determining whether or not the hand image area exists in the image area of interest is illustrated here, the present invention is not limited thereto. is not. For example, the CPU 60 may determine whether or not the captured image is an ignition attraction image by determining whether or not a sleeve / hand image region exists in the image region of interest. The sleeve / hand image area refers to a series of image areas including a sleeve image area indicating the tip of the sleeve of the clothing and a hand image area. Whether or not it is a sleeve / hand image area is determined by determining whether or not the degree of coincidence with the hand sample image is adjacent to an image area having a third threshold value or more and the degree of coincidence with the sleeve sample image is greater than or equal to the fourth threshold value. It is determined whether or not the captured image is an ignition-triggered image by determining whether or not the image area exists. The sleeve sample image is a sample image showing the tip of the sleeve of the clothing, and a plurality of sleeve sample images having different contents are stored in the secondary storage unit 64 as a database. In this case, for example, there is an image region having a matching degree of 70% or more with any of the hand sample images, and an image region adjacent to this image region has an matching degree of 60% or more with any of the sleeve sample images. If it is an area, the photographed image is determined to be an ignition attraction image.

  In step 202, if the captured image indicated by the image information acquired in step 200 is an ignition attraction image, the determination is affirmed, and the routine proceeds to step 204. If it is determined in step 202 that the captured image indicated by the image information acquired in step 200 is not an ignition trigger image, the determination is negative and the process proceeds to step 206.

  In step 204, the CPU 60 executes the same process as in step 164, and then proceeds to step 206 shown in FIG.

  In step 206, the CPU 60 determines whether or not a condition for terminating the second control process (second control termination condition) is satisfied. As an example of the second control end condition, a condition that an instruction signal instructing the end of the second control process is input to the photographing / control device 14 or after the second control process is started. The condition that predetermined time (for example, 1 hour) passed is mentioned.

  If the second control end condition is not satisfied at step 206, the determination is negative and the routine proceeds to step 208. In step 206, if the second control end condition is satisfied, the determination is affirmed, and the second control process is ended.

  In step 208, the CPU 60 determines whether new image information is stored in the image storage unit 78. In step 208, if new image information is stored in the image storage unit 78, the determination is affirmed and the process proceeds to step 200. In step 208, if new image information is not stored in the image storage unit 78, the determination is negative and the process proceeds to step 206.

  Next, the third control process performed by the stove 12 when the CPU 100 executes the third control program 126 when the burner 24 of the stove 12 is ignited will be described with reference to FIG.

  In the third control process shown in FIG. 15, first, in step 250, the CPU 100 determines whether or not the WiFi communication unit 108 has received the thermal power reduction instruction information transmitted by the imaging / control device 14. In step 250, if the WiFi communication unit 108 receives the thermal power reduction instruction information transmitted by the imaging / control device 14, the determination is affirmed, and the process proceeds to step 252. In step 250, if the WiFi communication unit 108 has not received the thermal power reduction instruction information transmitted by the imaging / control device 14, the determination is negative and the process proceeds to step 260.

  In step 252, the CPU 100 controls the solenoid valve driving unit 116 so that the heating power of the burner to be controlled specified by the burner specifying information included in the heating power reduction instruction information received in step 250 is decreased, and then the process proceeds to step 254. Transition. That is, in step 252, the CPU 100 drives the electromagnetic valve 38 corresponding to the controlled burner to close the gas pipe 36 to extinguish the fire of the controlled burner. Here, fire extinguishing is illustrated as an example of a reduction in thermal power, but the present invention is not limited to this, and the thermal power may be reduced without extinguishing the fire. The control target burner specified by the burner specifying information in step 252 is an example of “a generation source of a position corresponding to the position of the specific heating power state image region”.

  In step 254, the CPU 100 determines whether or not a non-decreasing instruction flag described later is turned on. The non-decreasing instruction flag is a flag that instructs not to decrease the heating power of the burner to be controlled in the fourth control process, and is turned on in step 266 described later. In step 254, if the non-decreasing instruction flag is turned on, the determination is affirmed and the routine proceeds to step 256. In step 254, if the non-decrease instruction flag is not turned on (if turned off), the determination is negative, and the routine proceeds to step 258.

  In step 256, the CPU 100 turns off the non-decrease instruction flag, and then proceeds to step 258.

  In step 258, the CPU 100 determines whether or not a condition for ending the third control process (third control end condition) is satisfied. As an example of the third control end condition, the condition that the burner operation unit corresponding to the burner to be controlled has received a fire extinguishing instruction, or the touch panel 48B has received the end instruction of the third control process. Conditions are mentioned.

  If the third control end condition is not satisfied in step 258, the determination is negative and the routine proceeds to step 250. In step 258, when the third control end condition is satisfied, the determination is affirmed, and the third control process is ended.

  In step 260, the CPU 100 determines whether or not the WiFi communication unit 108 has received the heating power increase instruction information transmitted by the imaging / control device 14. In step 260, if the WiFi communication unit 108 receives the thermal power increase instruction information transmitted by the imaging / control device 14, the determination is affirmed, and the process proceeds to step 262. In step 260, if the WiFi communication unit 108 has not received the heating power increase instruction information transmitted by the imaging / control device 14, the determination is negative and the process proceeds to step 264.

  In step 262, the CPU 100 controls the solenoid valve driving unit 116 so that the heating power of the burner to be controlled whose thermal power has been decreased in step 252 increases, and then the process proceeds to step 254. Note that the control target burner whose thermal power has been reduced in step 252 is identified by the burner identification information included in the thermal power increase instruction information received in step 260. Here, the increase in the thermal power does not mean that the thermal power is excessive, but the thermal power set in advance as a thermal power larger than the thermal power after the decrease (for example, medium fire) means. The preset thermal power may be a thermal power set by default, or may be a thermal power customized in accordance with a user instruction received on the touch panel 48B.

  In step 264, the CPU 100 determines whether or not the WiFi communication unit 108 has received the non-decreasing instruction information transmitted by the imaging / control device 14. In step 264, if the WiFi communication unit 108 receives the non-decreasing instruction information transmitted by the imaging / control device 14, the determination is affirmed, and the process proceeds to step 266. In step 264, if the WiFi communication unit 108 has not received the non-decreasing instruction information transmitted by the imaging / control device 14, the determination is negative and the process proceeds to step 250.

  In step 266, the CPU 100 turns on the non-decrease instruction flag, and then proceeds to step 258. The non-decreasing instruction flag that is turned on in step 266 is a non-decreasing instruction flag that instructs not to reduce the heating power of the burner to be controlled that is specified by the burner specifying information included in the non-decreasing instruction information received in step 264. Point to.

  Next, the fourth control process performed by the stove 12 when the CPU 100 executes the fourth control program 128 when the first burner 24A is ignited will be described with reference to FIG.

  In the fourth control process shown in FIG. 16, first, in step 300, the CPU 100 determines whether or not the temperature measured by the temperature sensor 32 corresponding to the first burner 24A exceeds a fifth threshold (for example, 250 degrees). Determine. The fifth threshold value is predetermined (fixed in advance) as a temperature (temperature at which ignition is predicted (predicted ignition temperature)) based on the temperature measured by the temperature sensor 32 to reduce the thermal power of the first burner 24A. Temperature).

  In step 300, if the temperature measured by the temperature sensor 32 corresponding to the first burner 24A exceeds the fifth threshold value, the determination is affirmed, and the routine proceeds to step 302. In step 300, if the temperature measured by the temperature sensor 32 corresponding to the first burner 24A is equal to or lower than the fifth threshold, the determination is negative, and the routine proceeds to step 306.

  In step 302, the CPU 100 determines whether or not the non-decreasing instruction flag is turned off. In step 302, if the non-decreasing instruction flag is turned off, the determination is affirmed and the routine proceeds to step 304. In step 302, if the non-decreasing instruction flag is not turned off (if turned on), the determination is negative, and the routine proceeds to step 306.

  In step 304, the CPU 100 controls the electromagnetic valve driving unit 116 so that the heating power of the first burner 24 </ b> A is reduced, and then the process proceeds to step 306.

  In step 306, the CPU 100 determines whether or not a condition for terminating the fourth control process (fourth control termination condition) is satisfied. As an example of the fourth control end condition, there is a condition that the first burner operation unit 42 has received a fire extinguishing instruction, or a condition that the touch panel 48B has received a fourth control process end instruction. It is done.

  If the fourth control end condition is not satisfied in step 306, the determination is negative and the routine proceeds to step 300. In step 306, if the fourth control end condition is satisfied, the determination is affirmed and the fourth control process is ended.

  In the above description, the fourth control process when the first burner 24A is ignited is illustrated, but the fourth control process is also executed individually for each of the second burner 24B and the third burner 24C. That is, when the second burner 24B is ignited, in step 300, the CPU 100 compares the temperature measured by the temperature sensor 32 corresponding to the second burner 24B with the fifth threshold value. In step 304, the CPU 100 controls the solenoid valve drive unit 116 so that the heating power of the second burner 24B is reduced. If the third burner 24C is ignited, in step 300, the CPU 100 compares the temperature measured by the temperature sensor 32 corresponding to the third burner 24C with the fifth threshold value. In step 304, the CPU 100 controls the solenoid valve drive unit 116 so that the heating power of the third burner 24C is reduced.

  As described above, in the cooking system 10, the stove upper area 52 is photographed by the photographing / control device 14. Then, when there is an excessive thermal power state image region in the captured image obtained by shooting (step 158: Y), the thermal power by the burner 24 at a position corresponding to the position of the excessive thermal power state image region is reduced. The stove 12 is controlled (steps 164 and 252). Therefore, the cooking system 10 can reduce unnecessary thermal power as compared with the case where the thermal power is reduced without using a captured image obtained by imaging the stove upper area 52. As a result, cooking can always be performed with necessary and sufficient thermal power, which contributes to energy saving. Moreover, it also leads to suppression of the occurrence of sleeve fire.

  Further, in the cooking system 10, the excessive heat power state image region is an image region including a flame of a predetermined size or larger in the captured image. Therefore, the heating cooking system 10 indicates that the heating power for the upper stove region 52 is excessive as compared to a case where an image region including a flame of a predetermined size or larger in the photographed image is not set as an excessive power state image region. It can be easily identified from the captured image.

  Moreover, in the heating cooking system 10, the overhang flame image area | region (refer FIG. 10) is employ | adopted as an overheated state image area | region. Therefore, the heating and cooking system 10 can specify from the captured image with high accuracy that the heating power received by the cooking utensil is excessive as compared with a case where the protruding flame image area is not an excessive thermal power state image.

  Moreover, in the heating cooking system 10, a thermal power excessive state image area | region is an image area | region which shows the cooking area of a thermal power excessive state as a cooking area | region of the cooking appliance which has received the thermal power among the image areas in a picked-up image. Therefore, the heating cooking system 10 does not set an image region indicating a region including a cooking region with excessive thermal power as a cooking region of a cooking utensil receiving thermal power among image regions in the captured image as an excessive thermal power state image region. Compared to the case, it can be easily identified from the captured image that the heating power for the stove upper area 52 is excessive.

  Moreover, in the heating cooking system 10, a thermal power excessive state image area | region is an overheating image area | region (refer FIG. 11) and a foodstuff ignition image area | region (refer FIG. 12). Therefore, the heating cooking system 10 specifies from the captured image with high accuracy that the cooking region receives an excessive amount of thermal power compared to a case where the overheating image region and the cooked product ignition image region are not the excessive heating state image region. be able to.

  Moreover, in the heating cooking system 10, when the thermal power excessive state image area | region overlaps in each of the picked-up image acquired by image | photographing several times (step 162: Y), the redundant thermal power excessive state image area | region is overlapped. The stove 12 is controlled so that the thermal power generated by the burner 24 at the position corresponding to the position of is reduced (steps 164 and 252). Therefore, compared with the case where the heating cooking system 10 does not have the structure which reduces the thermal power by the burner 24 of the position corresponding to the position of the excessive thermal power state image area | region which overlaps with each of the picked-up image acquired by image | photographing several times. It is possible to suppress the occurrence of a situation in which the thermal power by the burner 24 is reduced although the thermal power is not excessive.

  Further, in the cooking system 10, when the overheated state image region is obtained in step 158 and then the reduced temperature state image region is obtained in step 182, the burner 24 at a position corresponding to the position of the reduced temperature state image region is obtained. The stove 12 is controlled so as to increase the heating power by (steps 184 and 262). Therefore, the heating cooking system 10 performs control to increase the thermal power by the burner 24 at a position corresponding to the position of the temperature-decreasing state image region when the temperature-decreasing state image region is obtained after the excessively thermal state image region is obtained. Compared with the case where it is not performed, it is possible to reduce the trouble of increasing the thermal power when the temperature is lowered.

  Further, in the cooking system 10, when it is not determined that the processing target area is the ignition attraction image area (step 188: N), the heating power is not reduced regardless of the temperature measured by the temperature sensor 32. The stove 12 is controlled (step 266, step 302: N). Accordingly, in the cooking system 10, the heating power is unnecessarily reduced as compared with the case where the heating power is reduced according to the temperature measured by the temperature sensor 32, although the cooking area is not in a state of inducing ignition. The occurrence of the situation can be suppressed.

  As a result, for example, cooking can be continued without weakening the heating power during cooking (such as a grill) that does not use cooking oil as an ignition source. Also, depending on the type of cooking utensil, the actual cooking utensil temperature may be lower than the temperature measured by the temperature sensor 32. Even in such a case, cooking should continue without weakening the heating power. Is possible.

  Moreover, in the cooking system 10, when it determines with a process target area | region being an ignition attraction image area | region (step 188: Y), according to the temperature measured by the temperature sensor 32, a stove is set so that a thermal power may reduce. 12 is controlled (step 304). Therefore, the heating and cooking system 10 can reduce the thermal power when the cooking area is in a state of inducing ignition, as compared with the case where the thermal power is reduced only depending on the temperature measured by the temperature sensor 32.

  Moreover, in the heating cooking system 10, when it determines with a picked-up image being an ignition attraction image (step 202: Y), the stove 12 is controlled so that a thermal power reduces (step 252). Accordingly, the heating cooking system 10 suppresses the occurrence of ignition on the stove upper area 52 (for example, the occurrence of sleeve fire) compared to the case where the captured image is not configured to determine whether or not the captured image is an ignition attraction image. can do.

  Moreover, in the heating cooking system 10, the specific heating power state image area | region (for example, excessive heat power state image area | region, a temperature fall state image area | region, or an ignition attraction image area | region) which shows the area | region of the specific heating power state in the stove top area | region 52 is shown. ) Is present in the captured image, the heating power by the burner 24 at the position corresponding to the position of the specific heating power state image area is adjusted (steps 252, 262, 304). Therefore, the heating cooking system 10 has a specific heating power state region in the stove top region 52 (compared to a case where a specific heating power state region in the stove top region 52 is detected without using a captured image. In the example shown in FIG. 10, the heating power of the rectangular region 102) in plan view can be adjusted.

  In the above embodiment, the image processing system program and the stove side program are exemplified, but this is only an example. Therefore, it goes without saying that unnecessary steps may be deleted, new steps may be added, and the processing order may be changed within a range not departing from the spirit. Each process included in each of the first control process, the second control process, the third control process, and the fourth control process described in the first embodiment is an ASIC (Application Specific Integrated Circuit) or a programmable logic device. May be realized by a hardware configuration such as the above, or may be realized by a combination of a hardware configuration and a software configuration.

  In the above embodiment, the case where the processing is sequentially performed on each of the three comparison target image regions extracted in step 152 of the first control processing is illustrated. Parallel processing may be performed on the image area.

  Moreover, although the case where WiFi communication was performed between the stove 12 and the imaging / control device 14 was illustrated in the above embodiment, the present invention is not limited to this, and the stove 12, the imaging / control device 14, Wireless communication may be performed between the two. Further, wired communication may be performed between the stove 12 and the photographing / control device 14.

  In the above embodiment, the case where the image processing system program is executed by the CPU 60 of the photographing / control device 14 is exemplified. However, the present invention is not limited to this, and a program corresponding to the image processing system program is provided. It may be executed by the CPU 100 of the stove 12.

  In the above embodiment, for the sake of convenience of explanation, the case where the reference image information and the ignition attraction image DB 92 stored in the secondary storage unit 64 are fixed is illustrated, but the present invention is not limited to this. is not. That is, the reference image information and the ignition attraction image DB 92 stored in the secondary storage unit 64 may be updated. In this case, the CPU 60 may update the storage content of the secondary storage unit 64 by storing the information acquired from the external device (for example, the stove 12) via the WiFi communication unit 80 in the secondary storage unit 64. The update may be an update by overwrite registration or an update by additional registration.

  In the above embodiment, the case where the stove top area 52 is shot as a moving image by the shooting / control device 14 has been illustrated, but the present invention is not limited to this, and the shooting / control device 14 sets the stove top area 52 as a moving image. The region 52 may be captured as a still image.

  Moreover, in the said embodiment, the case where CPU60 determined whether the cooker image area | region exists in a process target area | region by determining whether the burner image area | region exists in a process target area | region was illustrated. However, the present invention is not limited to this. For example, sample images of various cooking utensils are stored in a database in advance, and the CPU 60 determines whether or not the cooking utensil image region exists in the processing target region by comparing the processing target region and the sample image. It may be.

  In the above embodiment, the photographing / control device 14 has been described as an example. However, the present invention is not limited to this, and a smart device with a camera is applied instead of the photographing / control device 14. The stove upper area 52 may be photographed by the camera of the smart device. In this case, the smart device receives various information necessary for executing the first control process and the second control process such as the image processing system program, the reference image information, and the ignition attraction image DB 92 from the external device via the communication unit. Get it. An example of the external device is a stove 12 or a server device on the Internet.

  Moreover, although the case where the stove top area | region 52 was image | photographed by the imaging | photography / control apparatus 14 from right above the top plate 22 was illustrated in the said embodiment, this invention is not limited to this. For example, as shown in FIG. 17, the stove upper area 52 may be photographed by the photographing / control device 14 from obliquely above the top plate 22. Further, the photographing / control device 14 is attached to a predetermined position (for example, a position just above the top plate 22) of the range hood (not shown) via a hinge mechanism (not shown), and the photographing angle is changed by the hinge mechanism. You may do it. As an example, as shown in FIG. 18, the photographing / control device 14 is attached to a slide mechanism 300 fixed to a range hood (not shown) so that the photographing / control device 14 is slid horizontally by the slide mechanism 300. It may be.

  Moreover, although the case where the stove top area | region 52 was image | photographed only by the imaging | photography / control apparatus 14 was illustrated in the said embodiment, this invention is not limited to this. For example, as shown in FIG. 19, the upper stove area 52 is photographed from each of two directions different from the photographing / control device 14 by each of the photographing / control devices 302 and 304 having the same function as the photographing / control device 14. You may be made to do. In this case, the CPU 100 of the stove 12 controls the heating power of the burner 24 based on the heating power decrease instruction information, the heating power increase instruction information, and the non-decreasing instruction information transmitted by each of the imaging / control devices 14, 302, 304.

  For example, when the CPU 100 receives the thermal power reduction instruction information transmitted by any of the imaging / control devices 14, 302, 304, the control target burner specified by the burner identification information included in the thermal power reduction instruction information The solenoid valve driving unit 116 is controlled so that the heating power of the motor is reduced. Further, when the CPU 100 receives the thermal power increase instruction information transmitted by any of the imaging / control devices 14, 302, 304, the control target burner specified by the burner identification information included in the thermal power increase instruction information The solenoid valve driving unit 116 is controlled so that the heating power of the valve increases. Furthermore, when the CPU 100 receives the non-decreasing instruction information transmitted by any of the imaging / control devices 14, 302, 304, the control target burner specified by the burner identification information included in the non-decreasing instruction information. Turn on the non-decrease indication flag for.

  Further, in the above-described embodiment, in order to increase the reliability of the determination as to whether or not the thermal power is in the excessive state, in the first control process shown in FIG. 8, the CPU 60 continues the thermal power excessive state image region in step 160. In step 162, it is determined whether or not the count value exceeds the first threshold. However, the present invention is not limited to this. For example, if immediacy is more important than reliability, The first threshold value may be reduced. If further immediacy is desired, the processing in step 164 is executed without executing the processing in steps 160 and 162 on the condition that the overheated state image region is obtained in step 158. May be.

  Moreover, although the said embodiment illustrated the case where it was determined whether a process target area | region was a temperature fall state image area | region based on the difference of a process target area | region and the excessive thermal power state image area | region obtained previously. However, the present invention is not limited to this. For example, a sample image indicating a temperature drop state is stored in a database in advance, and the CPU 60 compares the processing target area with the sample image, and the degree of coincidence with the processing target image is 80% or more. May be determined to be the temperature decrease state image area. Further, when it is determined whether or not the processing target area is an excessive heat state image area, the determination may be made by the same method.

  As described above, when comparing the processing target area with the sample image, the more the number of sample images stored in the database, the more the processing target area is the temperature-decreased state image area (or the overheated state image area). It becomes possible to increase the accuracy of the determination of whether or not. Note that the sample images are preferably classified for each cooking environment. Here, the cooking environment is specified by, for example, a cooking utensil to be used and cooking contents (for example, a cooking name). In this case, for example, information for specifying the cooking utensil to be used and information for specifying the cooking content are received on the touch panel 48B before cooking, and only the sample image corresponding to each received information is used for comparison with the captured image. That's fine. By narrowing down the number of sample images to be compared in this way, the processing load on the CPU 60 is reduced as compared with a case where all sample images are compared with the processing target region.

  Moreover, in the said embodiment, the case where CPU60 determines whether the process target area | region in one picked-up image is a temperature fall state image area | region in step 182 of the 1st control processing shown in FIG. However, the present invention is not limited to this. For example, the CPU 60 determines whether or not each processing target area of a plurality of (for example, 10) captured images obtained in succession is a temperature-decreasing state image area. You may do it. In this case, the CPU 60 may transmit the thermal power increase instruction information to the stove 12 when each of the processing target areas of the plurality of captured images obtained in succession is the temperature decrease state image area. This suppresses the occurrence of a situation in which the thermal power increases despite the fact that the temperature is not lowered.

  Moreover, in the said embodiment, in step 188 of the 1st control process shown in FIG. 9, the case where CPU60 determined whether the process target area | region in one picked-up image is an ignition attraction image area was illustrated. However, the present invention is not limited to this. For example, the CPU 60 may determine whether or not each processing target region of a plurality of (for example, ten) captured images obtained in succession is a firing attraction image region. In this case, when the CPU 60 determines that each processing target area of the plurality of captured images obtained in succession is the ignition attraction image area, the CPU 60 transmits the thermal power reduction instruction information to the stove 12. In this case, non-decreasing instruction information may be transmitted to the stove 12. As a result, the occurrence of a situation in which the thermal power is reduced in spite of the fact that the ignition is not induced is suppressed.

  In the above embodiment, the case where the CPU 60 determines whether or not one captured image is an ignition attraction image in step 202 of the second control process shown in FIG. 13 is not limited to this. For example, the CPU 60 may determine whether each of a plurality of (for example, ten) captured images obtained in succession is an ignition attraction image. In this case, if the CPU 60 determines that each of a plurality of continuously obtained captured images is an ignition attraction image, the CPU 60 may transmit the thermal power reduction instruction information to the stove 12. As a result, it is possible to suppress the occurrence of a situation in which the thermal power is reduced although the ignition is not induced.

  Moreover, although the said embodiment demonstrated the case where the thermal power state was estimated based on the aspect of a cooking area | region and the magnitude | size of a flame, and the control according to the estimated thermal power state was performed, this invention is limited to this is not. For example, when cooking with a cooking utensil designed to change color according to temperature, the color of the cooking utensil may be detected from the captured image, and the thermal power state may be estimated based on the detected color. . Further, the area of the burnt area in the cooking area (for example, the number of pixels in the burnt color area indicating the burnt color) may be detected, and the thermal power state may be estimated based on the detected area of the burnt area.

  In addition, as an example of a cooking utensil designed to change color according to temperature, a cooking utensil having a function of changing the emission color of the LED lamp when hot water boils, or a paint that changes color depending on temperature is applied. Cooking utensils and the like.

  Moreover, although the case where the magnitude | size of the thermal power was estimated based on the color picked-up image was illustrated in the said embodiment, this invention is not limited to this. For example, you may make it estimate the magnitude | size of a thermal power based on the thermal image obtained by imaging | photography with thermography.

  In the above-described embodiment, the CPU 100 extracts the comparison target image area from the captured image and determines whether or not the extracted comparison target image area is an overheated state image area. For example, the CPU 100 may determine whether or not the captured image is a thermal power excessive state image indicating an excessive thermal power state without extracting the comparison target image region from the captured image.

  In this case, for example, a sample image indicating an excessive state of thermal power is stored in a database in advance, the captured image is compared with the sample image, and the captured image is present when there is a sample image having a matching degree of 80% or more. May be determined to be an overheated state image.

  As described above, when comparing the captured image and the sample image, the more the number of sample images stored in the database, the higher the accuracy of determining whether the captured image is an overheated state image. Is possible. Note that the sample images are preferably classified for each cooking environment. Here, the cooking environment is specified by, for example, the burner 24 to be used, the cooking utensil to be used, and the cooking content (for example, the name of the dish). In this case, for example, on the touch panel 48B before cooking, information for specifying the burner 24 to be used, information for specifying the cooking utensil to be used, and information for specifying the cooking content are received, and only sample images corresponding to each received information are received. May be used for comparison with the photographed image. By narrowing down the number of sample images to be compared in this way, the processing load on the CPU 60 is reduced as compared with a case where all sample images and captured images are compared.

  Note that the information for specifying the burner 24, the information for specifying the cooking utensil to be used, the information for specifying the cooking content, etc. are not necessarily input to the stove 12 via the touch panel 48B. For example, information for specifying the burner 24, information for specifying the cooking utensils to be used, and information for specifying the cooking contents are provided on the stove 12 by a smart device or a remote controller that controls the stove 12 by performing wireless communication with the stove 12. You may make it transmit to.

  In the above embodiment, the CPU 100 extracts the comparison target image region from the captured image, and determines whether or not the extracted comparison target image region is the temperature decrease state image region. For example, the CPU 100 may determine whether or not the captured image is a temperature decrease state image indicating the temperature decrease state of the stove top region 52 without extracting the comparison target image region from the captured image. . In this case as well, it is possible to determine with high accuracy whether or not the captured image is a temperature-decreased state image by using a method similar to that for determining whether or not the captured image is an excessive heat state image. It becomes.

  In the above embodiment, the CPU 100 extracts the comparison target image area from the photographed image and determines whether or not the extracted comparison target image area is the ignition attraction image area. It is not limited to. For example, the CPU 100 does not extract the comparison target image area from the photographed image, and determines whether or not the photographed image is an ignition attraction image indicating a state of inducing the ignition in the cooking area of the cooking utensil. Good. Also in this case, it is possible to determine with high accuracy whether or not the photographed image is the ignition attraction image by using a method similar to that for determining whether or not the photographed image is the excessively thermal image. Become.

  Moreover, although the case where the three burners 24 were mounted in the stove 12 was illustrated in the said embodiment, this invention is not limited to this, This book is also applied to the stove with only one burner. The invention is applicable. In this case, for example, the CPU 100 may determine the thermal power state of the burner, the heating state with respect to the cooking area, and the like based on a captured image obtained by photographing the burner with only one burner. In this case, the process performed for each comparison target image area in the first control process shown in FIG. 8 may be performed for each captured image. In this way, when only one burner is mounted on the stove, there is no need to extract a plurality of comparison target image areas, so that the processing load on the CPU 100 is reduced compared to the example described in the above embodiment. The

  Moreover, in the said embodiment, although CPU60 determined the thermal power state of the burner 24 and performed the control according to the determined thermal power state, this invention is not limited to this. For example, the CPU 60 may determine a heating state by an electromagnetic coil of a so-called IH cooker and perform control according to the determined heating state.

  In this case, in the first control process shown in FIG. 8, in step 158, it is determined whether or not the processing target area is an excessive heating power state image area. The heating power excessive state image region is roughly divided into the above-described overheating image region and the cooked product ignition image region. In Steps 164 and 190, heating power reduction instruction information including coil specifying information for specifying an electromagnetic coil to be controlled is transmitted to the IH cooker. In Step 184, heating power increase instruction information including coil identification information is transmitted to the IH cooker. Further, in step 192, non-decreasing instruction information including coil identification information is transmitted to the IH cooker.

  When the IH cooker receives the heating power reduction instruction information, the heating power (W: Watt) is reduced by reducing the electromagnetic force of the electromagnetic coil specified by the coil specifying information included in the heating power reduction instruction information. In addition, when receiving the heating power increase instruction information, the IH cooker increases the heating power by increasing the electromagnetic force of the electromagnetic coil specified by the coil specifying information included in the heating power increase instruction information. Furthermore, when the non-decreasing instruction information is received, the IH cooker turns on a non-decreasing instruction flag that instructs not to decrease the electromagnetic force of the electromagnetic coil specified by the coil specifying information included in the non-decreasing information. When the non-decreasing instruction flag is turned off, the electromagnetic force of the electromagnetic coil is reduced in step 304 shown in FIG. 16, and when the non-decreasing instruction flag is turned on (determination is denied in step 302 shown in FIG. 16). ) Electromagnetic force of the electromagnetic coil does not decrease.

  In the above-described embodiment, an example in which the thermal power is reduced when a protruding flame image area is obtained has been described. When the small cooking utensil image area indicating the state is obtained, the stove 12 is controlled by the burner 24 corresponding to the position of the small cooking utensil image area so that the flame does not overflow around the cooking utensil. Good. Thereby, the overflow of the flame when the cooking utensil of less than a predetermined | prescribed magnitude | size is set | placed in five virtues is suppressed.

  This control is preferably performed during the period from when the burner 24 is ignited until the overheated state image region is obtained. The small cooking utensil image area refers to an image area showing a rectangular area in plan view in a state where cooking utensils having a size less than a predetermined size are placed on the virtues 28.

  The predetermined size refers to the overall size of the cooking utensil including the main body of the cooking utensil and the gripping part connected to the main body, or the size of the main body of the cooking utensil. An example of the predetermined size is an absolute size or a relative size. The absolute size refers to the size of the main body of the cooking utensil itself. As an example of the absolute size, when the burner 24 is set to a medium fire in a state where the main body portion of the cooking utensil is placed at the central portion of the virtues 28, A predetermined size may be mentioned as the size of the lower limit of the main body of the cooking utensil that does not overflow with flames.

  The relative size refers to a size determined according to a relative ratio between the size of the reference object and the size of the main body of the cooking utensil. As an example of the relative size, the ratio of the area in plan view of the main body of the cooking utensil to the area of the circumscribed circle in plan view of Gotoku 28 is predetermined as the size of the main body of the cooking utensil below a predetermined ratio. The size is given. An example of the predetermined ratio is 60%, but this is only an example.

  In the above-described embodiment, the example has been described in which the thermal power is reduced when the overhang flame image area is obtained regardless of the position of the cooking utensil placed on the virtues 28. When a cookware misalignment image region is obtained in which a region where the virtues 28 are covered with the cookware is deviated in a direction opposite to the direction in which the cook is present, the flame does not overflow around the cookware. Alternatively, the stove 12 may be controlled. Here, the stove 12 is controlled so that the flame does not overflow around the cooking utensil, for example, the stove so that the flame does not overflow around the cooking utensil by the burner 24 corresponding to the position of the cooking appliance misalignment image area. 12 is controlled.

  This control is preferably performed during the period from when the burner 24 is ignited until the overheated state image region is obtained. The cookware misalignment image area refers to an image area showing a rectangular area in plan view in a state where the area where the virtues 28 are covered with the cookware is biased in the direction opposite to the direction of the cook. The reverse direction of the direction in which the cook exists is, for example, the reverse direction of the front side of the counter 16, that is, the back side of the stove 12. For example, the state of being overweight is, for example, that most of the area on the back side of the stove 12 in Gotoku 28 (for example, 70% or more) is covered with cooking utensils, whereas the near side of the stove 12 in Gotoku 28 is It refers to the state where most of the area is not covered with cooking utensils. Therefore, even in such a state, the stove 12 is controlled so that the flame does not overflow around the cooking utensil, thereby suppressing ignition of the cook.

  Moreover, in the said embodiment, each process based on the determination of each presence / absence of a thermal power excessive state image area | region and a temperature fall state image area | region in 1st control processing, and the thermal power increase control and thermal power reduction control in 3rd control processing were illustrated. However, the present invention is not limited to this. That is, according to the present invention, each process based on the presence / absence of each of the excessive heat power state image region and the low temperature state image region in the first control process, and the thermal power increase control and the thermal power decrease control in the third control process are not performed. Even true.

  In this case, for example, the CPU 60 does not execute the processes of steps 156 to 168 and steps 176 to 186 in the first control process shown in FIG. 8, and when the process of step 154 is completed, the process of the flowchart shown in FIG. Should be executed. On the other hand, in the third control process shown in FIG. 15, the CPU 100 executes steps 264, 266, and 258 without executing the processes of steps 250 to 256, 260, and 262, and accompanies the end of the process of step 258. The non-decrease instruction flag may be turned off.

  Moreover, although the case where the 2nd control process was performed was illustrated in the said embodiment, this invention is materialized even if a 2nd control process is not performed.
