Description

The present invention relates to an image display device and a method for controlling its operation, and in particular to a game device that displays game images and a method for controlling its operation.

Techniques are known that adjust the brightness of a portion of an image to reduce power consumption when an image is displayed on a display. For example, in a mobile terminal device that scrolls content images by flicking, a technique is known that reduces power consumption by lowering the brightness of an image other than the image displayed on the display when the image scrolls on the display after a flicking operation (Patent Document 1).

In addition, in order to improve the visibility of the displayed image regardless of the brightness of the surroundings of the display, a technique is known that adjusts the brightness of the displayed image according to the brightness of the surroundings of the display. For example, in a liquid crystal television device in which a light receiving element is provided on the front side of the liquid crystal display panel, a technique is known in which the voltage applied to the liquid crystal layer of the liquid crystal display element is changed according to the brightness of the surroundings detected by the light receiving element, thereby changing the brightness of the entire displayed image (Patent Document 2).

In recent years, there has been a demand for further diversification of image display methods, and image display devices are being considered that have a plurality of regions within the image display area of a display, each capable of displaying an image independently. For such image display devices, a method is required to improve the visibility of the displayed image in each region. However, with the above-mentioned conventional image display technology, it is difficult to sufficiently improve the visibility of the displayed image in each region.

1. Overview of the Game First, a game executed by the game device 1 of this embodiment will be described. The game device 1 can execute, for example, a fighting game or a role-playing game using the recording medium 11. Specifically, the game device 1 acquires information on the characters (hereinafter referred to as "character information") recorded on the recording medium 11 by scanning the recording medium 11. Thereafter, the game device 1 displays an image of the character on the display unit 6. This allows the game device 1 to execute a fighting game in which the character fights against an enemy (opponent) character. After the game ends, a new recording medium 11 is dispensed from the game device 1. Note that the games executed by this game device 1 are not limited to the above-mentioned games.

2. Recording medium The recording medium 11 used in the game device 1 of this embodiment is not particularly limited as long as it can store character information. Such a recording medium 11 is formed in a card shape, for example, as shown in FIG. 2. The recording medium 11 has a two-dimensional code 111 on the surface. Character information, item information, and the like are recorded in this two-dimensional code 111. Examples of the two-dimensional code 111 include QR code (registered trademark) and Zcode (registered trademark). In the case of Zcode, the information is recorded so that it can be identified under invisible light (infrared rays). The recording medium 11 may be an IC card for a game that stores player information and character information. The recording medium 11 may also be formed in an oval shape, a circle shape, a square shape, or the like.

3. Game Device Next, the game device will be described. As shown in FIG. 1, the game device 1 of this embodiment includes two game devices (first sub game device 1A, second sub game device 1B) that are provided adjacent to each other. This game device 1 has one display unit 6 and is controlled by one control unit 8. Therefore, the size of the entire game device 1 can be made small. This allows the cost of the entire game device 1 to be reduced. The game device 1 of this embodiment is not limited to a configuration in which two game devices are provided adjacent to each other (2-in-1 configuration), and may be a configuration in which three or more game devices are provided adjacent to each other.

At first glance, the game device 1 of this embodiment looks like two game devices arranged next to each other. However, these two game devices are connected to form a single game device 1. Therefore, each player (user) can play on their own sub-game device, and can also cooperate to play a single game. As shown in Figures 1 and 3, this type of game device 1 has a housing 2, an operation unit 3, a reading unit 4, a speaker 5, a display unit 6, an illuminance detection unit S, a memory unit 7, a control unit 8, and a communication unit 9. The configuration of each unit will be described below.

The housing 2, operation unit 3, reading unit 4 and speaker 5 of the game device 1 are the same as the sub-housing 2A, first sub-operation unit 3A, sub-reading unit 4A and sub-speaker 5A for the first sub-game device 1A, and the sub-housing 2B, second sub-operation unit 3B, sub-reading unit 4B and sub-speaker 5B for the second sub-game device 1B. Therefore, in the following, only the components of the game device 1 will be described as a representative.

<Case>
The cabinet 2 has a function of installing or storing each component of the game device 1. As shown in FIG. 1, the cabinet 2 is formed in a substantially rectangular parallelepiped shape, but is not limited to this. The cabinet 2 may be configured as a single cabinet (twin cabinet), or may be configured by connecting sub-cabinets for each sub-game device. In the case of a twin cabinet, the cabinet 2 is formed symmetrically, and the center of the cabinet 2 (particularly the front) may be recessed inward. This allows the player to see at a glance that there are two game devices.

The cabinet 2 has a maintenance door 21 for the game manager to maintain and manage the operation rate of the game device 1 and the distribution rate of the recording medium 11. The door 21 is provided on the front of the cabinet 2. The door 21 has the function of accessing a maintenance panel 22 housed in the cabinet 2. As shown in FIG. 14, a maintenance panel (electronic device) 22 is arranged on the back side of the door 21. The maintenance panel 22 is composed of buttons for the game manager to test and manage the game device 1. With this configuration, for example, when it is desired to reset the game of the first sub-game device 1A, the game of the first sub-game device 1A can be independently managed without interrupting play on the second sub-game device 1B. Note that the door 21 is not an essential element of the game device 1.

<Operation section>
The operation unit 3 has a function of receiving operation inputs made by the player to execute the game. The operation unit 3 is composed of four push buttons 31 and two rectangular operation fields 32. The push buttons 31 are provided symmetrically on the front side of the top surface of the housing 2. The operation fields 32 are provided on the top surface of the housing 2, behind the push buttons 31. The shape and position of the operation fields 32 are not particularly limited, and each may be rod-shaped or circular, or may be located between the push buttons 31 or in front of the push buttons 31. Such an operation field 32 is a field where the player can place the recording medium 11 and move it. The operation field 32 is configured so that the reading unit 4 described later can read the recording medium 11.

The operation unit 3 includes a first sub-operation unit (first operation unit) 3A for the first sub-game device 1A, and a second sub-operation unit (second operation unit) 3B for the second sub-game device 1B. The first sub-operation unit 3A and the second sub-operation unit 3B can be operated independently, and can simultaneously receive different operation inputs. This makes it possible to execute different operations on the first sub-game device 1A and the second sub-game device 1B.

<Reading unit>
The reading unit 4 has a function of reading information from the recording medium 11 placed on the operation field 32. The reading unit 4 is provided inside the housing 2, below the operation field 32. Such a reading unit 4 is composed of, for example, an imaging device (camera) and an infrared light source. The infrared light source of the reading unit 4 irradiates infrared rays onto the two-dimensional code 111 of the recording medium 11 from the lower side of the operation field 32. In this state, the imaging device captures an image of the two-dimensional code 111 of the recording medium 11, so that the information recorded in the two-dimensional code 111 of the recording medium 11 can be read. Note that the reading unit 4 may be disposed anywhere in the housing 2 as long as the imaging device can capture an image of the operation field 32. Also, the reading unit 4 may be composed of only an imaging device.

<Speaker>
The speaker 5 has the function of outputting various sounds. The speaker 5 is provided at the back of the top surface of the cabinet 2, below the display unit 6. The number of speakers 5 is not particularly limited, and may be one or more than two. In this embodiment, two speakers 5 are provided on both sides of the back of the top surface of the cabinet 2 corresponding to each sub-game device. The sounds output by the speaker 5 include music and sound effects stored in the memory unit 7.

<Display section>
The display unit 6 has a function of displaying a game image (a predetermined image). As shown in Fig. 1, the display unit 6 is provided on the speaker 5 on the upper surface of the cabinet 2. The display unit 6 is composed of a single display panel, but may be a touch panel. As shown in Fig. 1, the display unit 6 is formed in a rectangular shape, but is not limited thereto, and may be formed in a circular or triangular shape.

The display unit 6 has a full screen area 61 that displays game images, and a frame 62 that is provided along the outer edge of the full screen area 61. The full screen area 61 includes individual areas 611 and partition areas 612. As shown in FIG. 5, the full screen area 61 has a function of displaying game images over the entire display unit 6. When a player of the first sub game device 1A and a player of the second sub game device 1B play cooperatively or against each other, a game image is displayed in the full screen area 61.

The individual area 611 includes an area (first area) 611A that displays game images for the first sub game device 1A, and an area (second area) 611B that displays game images for the second sub game device 1B. These areas 611A, 611B are configured with the same area, with a partition area 612 between them, as shown in FIGS. 4 and 6. This allows the player to see at a glance that there are two game devices. However, the area of one of the areas may be configured to be smaller than the area of the other area. For example, when a competitive game is being played between the first sub game device 1A and the second sub game device 1B, if the area 611A for the first sub game device 1A is large, the game image for the first sub game device 1A is displayed large. In such a case, the player can be given the impression that the player of the first sub game device 1A is dominant.

The first area 611A is provided to correspond to the first sub-operation unit 3A of the first sub-game device 1A. The first area 611A is formed in a rectangular shape, but is not limited to this. The second area 611B is provided to correspond to the second sub-operation unit 3B of the second sub-game device 1B. The second area 611B is formed in a rectangular shape, but is not limited to this. The first area 611A may display the same image as the image displayed in the second area 611B, or a different image. Furthermore, the first area 611A and the second area 611B can each display an image independently.

The partition region (third region) 612 has the function of separating the first region 611A from the second region 611B. Therefore, the partition region 612 is provided between the first region 611A and the second region 611B. The shape of the partition region 612 is not particularly limited, and may be elongated (FIG. 4), rectangular, or substantially trapezoidal (FIG. 6). The area of the partition region 612 is not particularly limited, and may be larger or smaller than the area of the first region 611A or the second region 611B. The partition region 612 may be further divided into a plurality of regions.

For example, as shown in FIG. 4, the partition area 612 may be divided along its short side to have two partition areas. That is, the partition area 612 may have a first partition area 612A for the first area 611A and a second partition area 612B for the second area 611B. Also, as shown in FIG. 6, the partition area 612 may be divided along its long side to have two partition areas. That is, the partition area 612 may have a third partition area 612C for a game image and a fourth partition area 612D for a text image. In this way, multiple images, mutually different images, can be displayed in the partition area 612.

The frame body 62 is provided on the speaker 5 or the housing 2. The frame body 62 is formed in a rectangular shape, but is not limited to this. For example, the frame body 62 may be formed in any shape, such as a circle or an ellipse. The frame body 62 has a joint 621 formed in the center of its long side so as to be recessed inward. This joint 621 forms the frame body symmetrically. Therefore, the display unit 6 can be seen as two display units, such as a sub-display unit 6A for the first sub-game device 1A and a sub-display unit 6B for the second sub-game device 1B.

The frame body 62 may include a first frame member 62A for the first sub game device 1A and a second frame member 62B for the second sub game device 1B. As shown in FIGS. 4 to 6, the first frame member 62A and the second frame member 62B are formed in a roughly "C" shape. One end and the other end of the first frame member 62A are in contact with one end and the other end of the second frame member 62B, respectively, to form a joint 621. With this configuration, the first frame member 62A and the second frame member 62B are arranged symmetrically with respect to the joint 621. Therefore, the display unit 6 can be seen as two display units.

As shown in FIG. 4, one end and the other end of the first frame member 62A are arranged opposite each other. Therefore, an image (partition image) that is the same as the appearance of the short side of the frame body 62 can be displayed in the first partition area 612A from one end to the other. This allows the first frame member 62A and the partition image to be connected to form a ring-shaped frame member (first frame member 62A). In other words, the partition image appears to be formed integrally with the first frame member 62A. This allows the player to recognize that the display unit 6 has a separate sub-display unit 6A.

On the other hand, one end and the other end of the second frame member 62B are arranged opposite each other. Therefore, an image (partition image) that is the same as the appearance of the short side of the frame body 62 can be displayed in the second partition area 612B from one end to the other. This allows the second frame member 62B and the partition image to be connected to form a ring-shaped frame member (second frame member 62B). In other words, the partition image appears to be formed integrally with the second frame member 62B. This allows the player to recognize that the display unit 6 has a separate sub-display unit 6B.

In this way, the first frame member 62A and the partition image form the frame body 62 for the first sub game device 1A. The second frame member 62B and the partition image form the frame body 62 for the second sub game device 1B. This allows one frame body 62 to be divided into two frame members 62A, 62B, and gives the player the impression that there are two game devices, even though there is only one game device 1. The first frame member 62A (first area 611A) and the first sub-operation unit 3A, and the second frame member 62B (second area 611B) and the second sub-operation unit 3B are arranged symmetrically with respect to the partition image as the central axis. Therefore, the player can be given the impression that there are two game devices.

<Illuminance detection section>
The illuminance detection unit S has a function of detecting the illuminance (brightness, chromaticity, etc.) around the display unit 6. The illuminance detection unit S is built in, for example, the upper long side of the frame body 62 of the display unit 6, and in this embodiment, is provided near the upper joint 621 of the first frame member 62A. For example, an optical sensor or an imaging device is used as such an illuminance detection unit S, but in this embodiment, an optical sensor is used. The optical sensor acquires the incident light as brightness and chromaticity signals of tristimulus values X, Y, Z, etc., and provides this signal information to the storage unit 7 ( FIG. 7 ).
A plurality of illuminance detection units S may be built into the frame 62. In this case, the predetermined parameters of the partition image are adjusted based on signal information from the plurality of illuminance detection units S, enabling more accurate adjustment. The illuminance detection unit S may be configured to be externally attached to the frame 62. Furthermore, when an imaging device is used as the illuminance detection unit S, it may be provided, for example, on the rear side of the operation field 32 of the operation unit 3 to detect the illuminance of the frame 62 of the display unit 6.

<Memory Unit>
Next, the storage unit 7 will be described. The storage unit 7 stores a game program and game data. The game program is a program for causing the game device 1 to execute a game, and is realized in cooperation with hardware. The game data is data related to the game, and includes character data, music data, image data, sound effect data, etc.

Character data is data such as the character's name, special move, weapon, and strength. Music data is song data played from the speaker 5. Music data includes multiple pieces of song data, such as songs by singers and game songs. Image data is game image data. Game image data includes data such as character images, background images, and various effect images. Sound effect data is sound data played during game play, and is different from music data. Sound effect data includes, for example, evaluation sound data that plays in response to the results of the player's operations.

In the game device 1 of this embodiment equipped with the illuminance detection unit S, the storage unit 7 stores data for adjusting the predetermined parameters of the partition image, as shown in FIG. 7. First, the chromaticity at various brightnesses (luminance) is measured for a plurality of types of frame bodies 62 with different color variations in advance using an imaging device or the like, and stored in the storage unit 7 as frame body information (frame body parameters). At this time, the location where the luminance and chromaticity are measured is the location where the illuminance detection unit S is provided. In this embodiment, the three attributes of color (hue, lightness, and saturation) calculated based on the luminance (luminous reflectance Y _a ) and chromaticity (xy chromaticity coordinates (x _a , y _a )) based on the CIE XYZ color system are the "predetermined parameters", but the "predetermined parameters" may be information on the luminance and chromaticity based on other color systems (for example, the RGB color system, the Yuv color system, etc.), other color systems, or signal information on either the luminance or chromaticity. Note that luminance (luminous reflectance Y _a ) based on the CIE XYZ color system corresponds to "lightness" among the three attributes of color, and chromaticity (xy chromaticity coordinates (x _a , y _a )) based on the CIE XYZ color system corresponds to "hue" and "saturation" among the three attributes of color.

The storage unit 7 also stores a predetermined threshold value corresponding to each frame body information (No. 1, 2, ...). The predetermined threshold value may be the same for all frame body information, or may be changed according to the brightness value. For example, as shown in FIG. 7, when the brightness is high (70% of No. 2), it is preferable to set the brightness and chromaticity threshold value high, and when the brightness is low (5% of No. 6), it is preferable to set the brightness and chromaticity threshold value low. This is because the brighter the surrounding environment, the more the objects to be compared look the same even if they differ to some extent in brightness and chromaticity, whereas the darker the surrounding environment, the more the objects to be compared look different due to slight differences in brightness and chromaticity.

The memory unit 7 stores the illuminance (detection value) detected by the illuminance detection unit S. The detected detection value, the frame information, and the threshold information are provided to the parameter determination means 86 and the parameter adjustment means 87, which will be described later.

The storage unit 7 stores predetermined events as shown in FIG. 8. The predetermined events include a boss character appearance event, a bonus event, a random battle event, a lucky character, and the like, as shown in FIG. 8. Such predetermined events are stored in association with a display area in which a game image should be displayed and a partition image that divides the display area. For example, a boss character appearance event A is associated with a display area in which only the full screen area 61 is displayed and there is no partition image. At this time, as shown in FIG. 5, an image is displayed in the full screen area 61. A boss character appearance event B is associated with a display area in which the individual area 611 and partition area 612 are displayed and there is no partition image, an image of a boss character B, and a text image that reads "Power 20%". At this time, a partition image is displayed in the partition area 612, as shown in FIG. 6.

Furthermore, for example, when one player is playing on the first sub game device 1A in the full screen area 61 and another player plays on the second sub game device 1B, an event is triggered. That is, the second sub-operation unit 3B of the second sub game device 1B receives an operation input for a random battle by the other player, and an event for random battle B is triggered. At this time, the display area for random battle B is associated with the individual area 611 and partition area 612, and the partition image is a bar image. At this time, the partition area 612 displays the partition image as shown in FIG. 4.

Furthermore, when a recording medium 11 with the same winning character is dispensed from the first sub game device 1A and the second sub game device 1B and play is executed on the first sub game device 1A and the second sub game device 1B, an event is triggered. In other words, when a player of the second sub game device 1B is executed during play on the first sub game device 1A, an event for the winning character is triggered. At this time, for example, as shown in FIG. 5, an image is displayed in the entire screen area 61.

<Control Unit>
Next, the control unit 8 will be described. The control unit 8 controls all functions related to the execution of the game. As shown in FIG. 3, the control unit 8 has an acquisition means 81, a game processing means 82, a display control means 83, a switching means 84, a partitioning means 85, a parameter determination means 86, a parameter adjustment means 87, and a sound output control means 88.

(Means of Acquisition)
The acquisition means 81 has a function of acquiring information on operation input by the player, character information and game information on the recording medium 11, etc. The acquisition means 81 acquires information on operation input by the player pressing the push button 31. This can receive operation input information from the first sub-operation unit 3A and the second sub-operation unit 3B simultaneously. Such information on operation input includes, for example, information on interrupt play and information on character selection. The acquisition means 81 also acquires character information and the like read by the reading unit 4. In addition, it acquires various other information acquired via the communication unit 9 described later.

(Game Processing Means)
The game processing means 82 has a function of processing the information acquired by the acquisition means 81 and the progress of the game. For example, the game processing means 82 determines information on game images stored in the storage unit 7 and provides it to the display control means 83. The game processing means 82 determines sound information and provides it to the sound output control means 88. The game processing means 82 also determines and activates a predetermined event. In this way, the game processing means 82 processes the progress of the entire game.

Here, the game processing means 82 may determine the specified event randomly, periodically, by receiving operational input from the player, or based on the number (multiple sheets) of winning recording media 11. As shown in FIG. 7, the game processing means 82 also determines a specific partition image corresponding to the specified event, but can also determine to display a specified image other than the partition image.

(Display control means)
The display control means 83 has a function of controlling the display of all images related to the game. That is, the display control means 83 controls the display of game image information provided by the game processing means 82 and the display of partition images by the partition means 85. For example, as shown in FIG. 4, the display control means 83 controls the display of game images in both the first area 611A and the second area 611B of the display unit 6 independently. Also, as shown in FIG. 5, the display control means 83 controls the display of game images in the full screen area 61. Also, the display control means 83 controls the display of linear partition images (FIG. 4) and partition images such as game images and character images (FIG. 6) in the partition area 612. Also, when information for adjusting predetermined parameters (hue, brightness, and saturation) of the partition images is provided by the parameter adjustment means 87, the display control means 83 controls the display of the partition images with the predetermined parameters adjusted. In this way, the display control means 83 can control the predetermined images to be displayed separately in each area of the display unit 6.

(Switching Means)
The switching means 84 has a function of switching between the full screen area 61 and the individual area 611 when a predetermined event is triggered by the game processing means 82 or when the operation unit 3 receives predetermined input information. Specifically, when a game is being played, the switching means 84 switches the display area of the display unit 6 from the individual area 611 to the full screen area 61, or from the full screen area 61 to the individual area 611, when the predetermined event is triggered or input information is received. That is, when a predetermined event occurs, the switching means 84 refers to the event table in Fig. 8 and performs control so as to switch the display area to the display area corresponding to the event.

Normally, the game device 1 is set so that each sub-game device executes a game individually. Therefore, a partition image is displayed in the partition area 612 between the first area 611A and the second area 611B. Therefore, when a predetermined event is triggered, the switching means 84 can simultaneously switch the display area from the first area 611A to the full screen area 61, and from the second area 611B to the full screen area 61.

On the other hand, when each sub-game device is set to cooperate with each other to execute a game, a game image is displayed in the full screen area 61. Therefore, when a specified event is triggered, the switching means 84 can switch the display area from the full screen area 61 to the individual area 611 (first area 611A and second area 611B) and the partition area 612.

(Partitioning Means)
The partition means 85 has a function of separating the first area 611A from the second area 611B, and is configured with a partition image. Specifically, when the switching means 84 switches the display area, the partition means 85 refers to the information table in FIG. 8 to identify the partition area 612 and the partition image corresponding to the event. The partition means 85 provides the display control means 83 with information on the identified partition area 612 and the partition image.

The partition image is not particularly limited as long as it can separate the first area 611A and the second area 611B. Therefore, the partition image may be a long image (bar image), a circular image, a curved image, a game image, a predetermined character image, or the like. For example, as shown in FIG. 8, when the event of the random battle B is triggered, the partition means 85 specifies the bar image of the partition image and the display area. The partition means 85 provides this information to the display control means 83. In this case, as shown in FIG. 4, a bar image is displayed in each of the first partition area 612A and the second partition area 612B. At this time, the bar image is configured with the same image as the appearance of the opposing frame member. As a result, the first frame member 62A and the bar image are visually recognized as if the first frame member 62A is formed in a frame shape. Also, the second frame member 62B and the bar image are visually recognized as if the second frame member 62B is formed in a frame shape. Therefore, the player can be made to recognize that there are two game devices.

Also, as shown in FIG. 8, when a boss character appearance A or hit character event is triggered, the partition means 85 determines that there is no partition image to display. Therefore, the partition means 85 provides information to the display control means 83 to erase the partition image that is being displayed. In this case, as shown in FIG. 5, the partition image is erased and the game image is displayed in the entire screen area 61. This allows two players to enjoy the game simultaneously on one display unit 6.

Also, as shown in FIG. 8, when the boss character appearance B event is triggered, the partition means 85 specifies the partition image "boss character B" and "power 20%" and the display area. The partition means 85 provides this information to the display control means 83. In this case, as shown in FIG. 6, the boss character B is displayed in the third partition area 612C, and a text image "power 20%" is displayed in the fourth partition area 612D. This allows the player to know how much power the boss character B has. The layout of the third partition area 612C and the fourth partition area 612D is not particularly limited, and the fourth partition area 612D may be positioned above the third partition area 612C.

(Parameter Determination Means)
The parameter determination means 86 determines the predetermined parameters (hue, lightness, and saturation) of the partition region 612 to be adjusted in accordance with the illuminance detected by the illuminance detection unit S. Specifically, the parameter determination means 86 determines the predetermined parameters of the partition region 612 by referring to the frame information and the detection value in the parameter adjustment data table (frame information, threshold information, detection value) shown in FIG.

The parameter determination means 86 calculates the deviation (difference) between the frame information (luminance and chromaticity) stored in the storage unit 7 and the detection value (luminance and chromaticity) detected by the illuminance detection unit S based on the data table shown in FIG. 7. For example, referring to the frame information No. 1 in FIG. 7, the luminance Y _a value to be displayed is 50%, whereas the detected luminance Y _b value is 55%. Therefore, the deviation of the luminance to be adjusted is 5% (=55-50). In addition, the xy chromaticity coordinates (x _a , y _a ) to be displayed are (0.46, 0.44), whereas the detected xy chromaticity coordinates (x _b , y _b ) are (0.52, 0.38). Therefore, the deviation of the xy chromaticity coordinates to be adjusted is 0.06 (=0.52-0.46) for the x coordinate and -0.06 (=0.38-0.44) for the y coordinate.

The deviation amounts of hue, lightness, and saturation calculated based on the deviation amounts of luminance and chromaticity calculated in this manner are determined as data for the specified parameters to be adjusted. The parameter determination means 86 provides the calculated deviation amounts to the parameter adjustment means 87. Note that in the above example, the deviation amounts are determined so that the luminance and chromaticity of the partition image completely match the luminance and chromaticity of the frame information, but the specified parameters to be adjusted may contain errors within the range in which the partition image and the frame 62 appear integrated.

(Parameter Adjustment Means)
The parameter adjustment means 87 has a function of adjusting the predetermined parameters (hue, lightness, and saturation) of the partition image displayed in the partition area 612 based on the predetermined parameters determined by the parameter determination means 86. The parameter adjustment means 87 may (i) always adjust the predetermined parameters of the partition image based on the deviation amount of the hue, lightness, and saturation determined by the parameter determination means 86, or (ii) adjust the predetermined parameters of the partition image only when the deviation amount exceeds a threshold range.
In the case of (i) above, the parameter determination means 86 subtracts or adds the deviation amount of the luminance and chromaticity (hue, value, and saturation) determined by the parameter determination means 86 from the luminance and chromaticity of the display data of the currently displayed partition image, thereby adjusting the luminance and chromaticity of the partition image so that they completely match the luminance and chromaticity of the frame information.

In the case of (ii) above, when the deviation amount of the luminance and chromaticity determined by the parameter determination means 86 based on the data table shown in FIG. 7 exceeds the threshold range, the parameter determination means 87 adjusts the luminance and chromaticity of the partition image in the same manner as in (i) above so that they completely match those of the frame information. On the other hand, if the deviation amount is within the threshold range, the predetermined parameters of the partition image are not adjusted. For example, in the frame information No. 1, the deviation amount of the luminance to be adjusted (5%) does not exceed the threshold range, but the deviation amount of the xy chromaticity coordinates to be adjusted (x: 0.06, y: -0.06) exceeds the threshold range, so the parameters of the partition image are adjusted. In the frame information No. 2, the deviation amount of the luminance to be adjusted (8%) is large, but does not exceed the threshold range, and the deviation amount of the xy chromaticity coordinates to be adjusted (x: -0.09, y: 0.05) does not exceed the threshold range either, so the parameters of the partition image are not adjusted.

In the game device 1 of this embodiment, the illuminance detection unit S detects the illuminance around the display unit 6, and adjusts predetermined parameters (hue, brightness, saturation, etc.) of the partition image according to the detected illuminance. Specifically, the display unit 6 displays the partition image according to the detected illuminance such that the frame 62 and the partition image appear integrated.
For example, when the game device 1 is installed in a relatively dark place, the brightness (reflectance) of the frame 62 of the display unit 6 decreases. Therefore, when the partition image of the partition area 612 is displayed with the same brightness as the display image of the individual area 611, the partition image may be too bright and the frame 62 and the partition image may not be seen as one body. In addition, depending on the color of the lighting in the place where the game device 1 is installed, the frame 62 and the partition image may not be seen as one body.

In contrast, in the game device 1 of this embodiment, the display unit 6 displays the partition image according to the detected illuminance so that the frame 62 and the partition image appear as one unit, so that the player can be given a stronger impression that there are two game devices, regardless of the location where the game device 1 is installed. In addition, because the partition image and the frame 62 appear as a more integrated unit, the visibility of the display images in each individual area 611A, 611B can be improved.

If a predetermined parameter of the partition image of the partition area 612 has been adjusted at the start of the game, the parameter adjustment means 87 cancels the adjusted parameter when the switching means 84 switches from each individual area 611 to the full screen area 61. Also, when the switching means 84 switches the display area from the full screen area 61 to the individual area 611 and the partition area 612, the parameter adjustment means 87 adjusts the predetermined parameter of the partition image again.

(Sound output control means)
The sound output control means 88 controls the output of all sounds and music related to the game. Specifically, the sound output control means 88 controls the output of music and sounds determined by the game processing means 82. The sound output means 88 provides sound and music information to the speaker 5, thereby enabling the speaker 5 to output the sounds and music.

In addition to the above configuration, the control unit 8 of the present invention may include an appearance change means having a function of changing the appearance of the partition image. The appearance change means can change the appearance of the partition image by receiving an operational input or randomly. For example, if the frame body 62 of the display unit 6 of the game device 1 as shown in FIG. 1 is changed to another frame body having a different appearance (design), the appearance change means can change the appearance of the partition image to match the appearance of the other frame member. The appearance change means can also change the color or design of the partition image specified by the partition means 85 and decorate the partition image with a pre-stored image. In this way, regardless of the appearance of the frame member, the partition image can be changed to match the appearance.

The control unit 8 may also include a mode change means for changing the play mode. The modes include a solo play mode, a versus play mode, a cooperative play mode, a tournament play mode, and the like. The mode change means can change the play mode by receiving an operational input, or randomly. The mode change means can execute this mode change at any time. When a mode change occurs, the control unit 8 executes the above-mentioned processing to correspond to the mode change.

<Communications Department>
The communication unit 9 has a function of communicating with an external network (LAN, WAN, Internet, etc.) or device via a wired or wireless connection. The game device 1 of the present invention may communicate data with other devices, such as other game devices or information terminals, via the communication unit 9. For example, the communication unit 9 can communicate with other devices to obtain music data or game programs. This allows the game programs to be updated, making it possible to provide the latest games. It should be noted that the game device 1 does not necessarily have to have the communication unit 9.

The image display device of the present invention has been described above as a game device 1, but in addition to the above-mentioned components, the game device 1 of this embodiment also has a coin slot, a coin return slot, and a recording medium 11 outlet on the front of the housing 2.

B. Operation Control Method of Image Display Device Next, an operation control method of the image display device of this embodiment will be described. In the following, for ease of understanding, an example will be described in which the image display device is a game device. FIG. 9 is a flowchart showing the flow of game processing of the game device according to the first embodiment of the present invention. FIGS. 10(a) and 10(b) are flowcharts showing processing related to parameter adjustment of a partition image in the game processing shown in FIG. 9, FIG. 10(a) is a flowchart showing processing for adjusting parameters after displaying a game image on the display unit, and FIG. 10(b) is a flowchart showing processing for adjusting parameters before displaying a game image on the display unit.

First, the flow of game processing of the game device, excluding processing related to parameter adjustment of partition images, will be described.
First, when a player inserts a coin, the display control means 83 controls the display of a game image. As a result, the display unit 6 displays the game image (S1). While the player is playing the game, the control unit 8 judges whether or not the game processing means 82 has triggered a predetermined event (S2). If the predetermined event has not been triggered, the process proceeds to step S1, and steps S1 to S2 are repeated. On the other hand, if a predetermined event has been triggered, the process proceeds to step S3.

In step S3, the control unit 8 determines whether or not a game image is displayed in the individual area 611 (S3). If the control unit 8 determines that a game image is displayed in the individual area 611, it determines that the game image is displayed in the first area 611A and the second area 611B, and that a partition image is displayed in the partition area 612. At this time, the switching means 84 switches the display area of the display unit 6 from the individual area 611 to the full screen area 61 (S4). Thereafter, the partition image is erased from the partition area 612 (S5). As a result, the display unit 6 displays the game image in the full screen area 61 (S6), and the process ends.

On the other hand, in step S3, if the control unit 8 determines that the game image is not displayed in the individual area 611, it determines that the game image is displayed in the full screen area 61. At this time, the process proceeds to step S7. Next, the control unit 8 determines whether or not to switch the full screen area 61 to the individual area 611 (S7). If the control unit 8 determines that the full screen area 61 will not be switched to the individual area 611, the process proceeds to step S6, where the game image continues to be displayed in the full screen area 61 (S6). This ends the process.

On the other hand, if the control unit 8 determines that the full screen area 61 should be switched to the individual area 611, the switching means 84 switches the display area from the full screen area 61 to the individual area 611 (S8). Then, the partition means 85 identifies a partition image, and the partition image is displayed (S9). After that, the process proceeds to step S1. In this manner, steps S1 to S9 are repeated.

Next, the process for adjusting the parameters of the partition image will be described. In this embodiment, the parameter adjustment process method for the partition image includes (i) a method of adjusting a predetermined parameter of the partition image according to the illuminance around the display unit 6 after or while displaying a game image on the display unit 6, and (ii) a method of adjusting a predetermined parameter of the partition image according to the illuminance around the display unit 6 before displaying a game image on the display unit 6.

In the method (i) above, as shown in FIG. 10(a), while the display unit 6 displays a game image (S1), the illuminance detection unit S detects the illuminance (brightness, chromaticity) around the display unit 6 (S11). The detected illuminance is provided to the storage unit 7, and a data table such as that shown in FIG. 7 is created. Next, the parameter determination means 86 refers to the data table and determines the amount of deviation between the frame information and the detection value (a specified parameter to be adjusted) (S12).

Next, the parameter adjustment means 87 refers to the data table and determines whether the amount of deviation exceeds the threshold range (S13). If the parameter adjustment means 87 determines that the amount of deviation exceeds the threshold range, it adjusts the amount of deviation from the luminance and chromaticity of the image data of the partition image currently being displayed (S14). The display unit 6 then displays the partition image with the adjusted hue, brightness, and saturation (S15). On the other hand, if the parameter adjustment means 87 determines in step S13 that the amount of deviation does not exceed the threshold range, i.e., the amount of deviation is within the threshold range, the parameter adjustment means 87 does not adjust the hue, brightness, and saturation of the partition image on the display unit 6.

In the method (ii) above, as shown in FIG. 10(b), when a player inserts a coin, the illuminance detection unit S detects the illuminance (brightness, chromaticity) around the display unit 6 before a game image is displayed on the display unit 6 (S11). The detected illuminance is provided to the storage unit 7, and a data table such as that shown in FIG. 7 is created. Next, the parameter determination means 86 refers to the data table and determines the amount of deviation between the frame information and the detection value (a specified parameter to be adjusted) (S12).

Next, the parameter adjustment means 87 refers to the data table and determines whether the deviation exceeds the threshold value (S13). If the parameter adjustment means 87 determines that the deviation exceeds the threshold value range, it adjusts the deviation from the brightness and chromaticity of the image data of the partition image to be displayed (S14). The display unit 6 then displays a game image including the partition image with the adjusted hue, brightness, and saturation (S15). The process then proceeds to step S2. On the other hand, if the parameter adjustment means 87 determines in step S13 that the deviation does not exceed the threshold value range, that is, the deviation is within the threshold value range, the parameter adjustment means 87 does not adjust the hue, brightness, and saturation of the partition image on the display unit 6. The display unit 6 then displays a normal game image (without adjusting the hue, brightness, and saturation of the partition image) (S1).

The above-mentioned processing method can be created by a program executed by a computer. Such a program is realized by a CPU (Central Processing Unit), a microprocessor, a GPU (Graphic Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc.

<<Second embodiment>>
Next, a second embodiment of the image display device of the present invention will be described with reference to the accompanying drawings.

Figure 11 is a plan view showing a schematic diagram of an image display device according to a second embodiment of the present invention. The second embodiment will be described below, focusing on the differences from the first embodiment described above, and omitting a description of similar points. Note that the same reference numerals are used to designate the same components as those in the first embodiment described above.

The image display device 100 of this embodiment differs from the game device 1 of the image display device of the first embodiment in that the operation unit 3 is configured as a touch panel and does not have a reading unit 4. Specifically, the image display device 100 of this embodiment is configured as a smartphone, as shown in FIG. 11. This image display device 100 has a display unit 6 having a first area 611A and a second area 611B, and an operation unit 3 having a first sub-operation unit 3A corresponding to the first area 611A and a second sub-operation unit 3B corresponding to the second area 611B. The processing of an image displayed in the first area 611A by the first sub-operation unit 3A and the processing of an image displayed in the second area 611B by the second sub-operation unit 3B can be executed simultaneously.

The image display device 100 of this embodiment displays images in the first area 611A and the second area 611B, while allowing the image in the first area 611A to be operated with the first sub-operation unit 3A, and the image in the second area 611B to be operated with the second sub-operation unit 3B. When a specified event is triggered, the switching means 84 switches the display area to the full screen area 61 combining the first area 611A and the second area 611B. At the same time, the partition means 85 deletes the partition image. In this way, the image display device 100 of this embodiment has the same effect as the image display device 1 of the first embodiment.

In this embodiment, the visibility of the display images in the areas 611A and 611B is improved by adjusting a predetermined parameter so that the partition image displayed in the partition area 612 appears integrated with the outer frame of the display unit 6 (the outer frame of the housing 2). Even though the image display device is a small smartphone, it is possible to give the player the impression that there are two game devices.
Note that the parameters of the partition image displayed in the partition region 612 do not necessarily have to be adjusted so as to be seen as one with the outer frame (housing 2) of the display unit 6. For example, in order to improve the sense of realism when an event occurs, the hue, brightness, and saturation may be temporarily adjusted so as to be more noticeable than the regions 611A and 611B.

In addition, the image display device 100 of this embodiment does not have a reading unit 4, so the device itself can be made smaller. In addition, the image display device 100 of this embodiment has the operation unit 3 and the display unit 6 overlapping each other, so the device itself can be made even smaller. Therefore, the costs required for the device can be reduced.

In addition, in this embodiment, as shown in FIG. 11, the partition area 612 is an elongated area connected to the opposing long sides of the display unit 6, but is not limited to this and may have various shapes, such as a shape with a part cut out or a divided shape.

<<Third embodiment>>
Next, a third embodiment of the image display device of the present invention will be described with reference to the accompanying drawings.

Figure 15 is a plan view showing a schematic diagram of a gaming device according to a third embodiment of the present invention. Figure 16 is an enlarged view showing a schematic diagram of the display unit of a gaming device according to a third embodiment of the present invention. The third embodiment will be described below, focusing on the differences from the first and second embodiments described above, and omitting a description of similar points. Note that the same reference numerals are used to designate the same components as those in the first embodiment described above.

15, the game device 1 of this embodiment differs from the game device 1 of the image display device of the first embodiment in that it does not have an illuminance detection unit S, and a parameter adjustment means 87 is configured to adjust predetermined parameters (hue, brightness, and saturation) of the partition image displayed in the partition area 612 by a direct operational input from the user. Also, in the game device 1 of this embodiment, the control unit 8 does not include a parameter determination means 86.
In the game device 1 of this embodiment, the parameter adjustment means 87 receives operational input from the user to change and adjust predetermined parameters (hue, lightness, and saturation) of the partition image of the partition area 612. This parameter adjustment means 87 can change and adjust the predetermined parameters of the partition image of the first partition area 612A or the second partition area 612B for each sub game device. In this case, the parameter adjustment means 87 can change and adjust the predetermined parameters of those partition images for each of the upper area, middle area, and lower area of the first partition area 612A.

For example, as shown in Fig. 16, the predetermined parameters of the partition image in the upper region of the first partition region 612A are displayed on the display unit 6 of the first sub game device 1A. Adjacent to each parameter name, a bar indicating the level of the parameter and the current percentage value are displayed. For example, the higher the percentage value of the parameter "saturation", the more vivid the color is indicated. The same is true for "hue" and "brightness". The parameter adjustment means 87 can also change and adjust the color parameters of the partition images in the upper region, middle region, and lower region all at once.
Therefore, even in the game device 1 having such a configuration, it is possible to adjust the predetermined parameters of the partition image so that the frame 62 and the partition image are seen as one body, depending on the illuminance around the display unit 6. Therefore, it is possible to obtain the same effects as those of the game device 1 of the first embodiment.

The operation control method of the image display device (game device) of this embodiment is the same as the operation control method of the image display device of the first embodiment described above, except for the processing related to parameter adjustment of the partition image. Specifically, the parameter adjustment processing method of the partition image of this embodiment includes (i) a method of adjusting a predetermined parameter of the partition image by direct operation input from the user after or while displaying a game image on the display unit 6, and (ii) a method of adjusting a predetermined parameter of the partition image by direct operation input from the user in advance before displaying a game image on the display unit 6.

The image display device and its operation control method of the present invention have been described above based on a preferred embodiment, but the present invention is not limited to this. The configuration of each part can be replaced with any configuration having a similar function. In addition, any other means or components may be added to the present invention. In addition, the present invention may be a combination of any two or more configurations (features) of the above-mentioned embodiments.

FIG. 12 is a front view, a plan view, and a bottom view showing a typical game device according to the first embodiment of the present invention, and FIG. 13 is a rear view and a left side view showing a typical game device according to the first embodiment of the present invention. The game device is made up of a single game device, but can give the impression of being made up of two separate and independent game devices.

According to the present invention, for example, in an image display device having two regions in the display region of a display unit, each of which can display an image independently, a predetermined parameter of a part of an image displayed between the two regions can be adjusted to improve the visibility of the image displayed in each region. In addition, since the predetermined parameter can be adjusted according to the illuminance around the display unit, an image display with excellent visibility can always be performed regardless of the illuminance in the environment in which the image display device is used. Furthermore, by adjusting a predetermined parameter of a part of an image, a part of the image and a part other than the display region of the display unit (for example, a frame portion) can be seen as one unit, thereby improving the visibility of an image displayed in a predetermined region of the display region. In this way, an image display device capable of displaying an image with excellent visibility in response to various image display forms can be provided. In addition, a method for controlling the operation of such an image display device can be provided. Therefore, the present invention has industrial applicability.
