2 is a block diagram illustrating an internal configuration of an information providing system according to an embodiment of the present invention, and FIG. 3 is a flowchart illustrating an information providing method according to an embodiment of the present invention.

As shown in FIG. 2, the information providing system 200 according to the present exemplary embodiment may include a processor 210, a bus 220, a network interface 230, a memory 240, and a database 250. . The memory 240 may include an operating system 241 and a service providing routine 242. The processor 210 may include a code recognizer 211, an information extractor 212, an information determiner 213, and an information provider 214. In other embodiments, the information providing system 200 may include more components than some of the components of FIG. 2 or some components may be omitted.

The memory 240 is a computer-readable recording medium and may include a permanent mass storage device such as random access memory (RAM), read only memory (ROM), and a disk drive. In addition, the memory 240 may store program codes for the operating system 241 and the service providing routine 242. These software components may be loaded from a computer readable recording medium separate from the memory 240 using a drive mechanism (not shown). Such a separate computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, a memory card, and the like. In other embodiments, the software components may be loaded into the memory 240 via the network interface 230 rather than the computer readable recording medium.

The bus 220 may enable communication and data transmission between components of the information providing system 200. The bus 220 may be configured using a high-speed serial bus, a parallel bus, a storage area network and / or other suitable communication technology.

The network interface 230 may be a computer hardware component for connecting the information providing system 200 to a computer network. The network interface 230 may connect the information providing system 200 to a computer network through a wireless or wired connection.

The database 250 is configured by the code scanning app, and serves to store and maintain the combination of the color information printed on the QR code and the channel information.

For example, when a red green blue (RGB) color is printed on a QR code, the database 250 may store and maintain information indicated by a combination of RGB colors. For example, RRR may be stored as channel 1, RRB is channel 2, RRG is channel 3, RBR is channel 4, and the like. In this case, when three colors are used in the QR code, 3 ³ = 27 color combination information may be matched with the channel information and stored in the database 250. In addition, when two colors are used, 3 ² = 9 color combination information and channel information may be matched and stored. When K colors are used, 3 ^K color combination information may be matched with the channel information and stored. Can be.

Here, the channel information is matched with the color combination information and is described as an example. However, this is an embodiment, and the simple information other than the channel information is matched with the color combination information to be stored and maintained in the database 250. Can be. For example, as the simple information, a broadcast program name, a broadcast company (KBS, SBS, MBC, A home shopping, B home shopping, etc.) may be used.

In addition, the database 250 stores and maintains detailed information included in the QR code in relation to the QR code. Here, the detailed information may indicate various information such as an image, text, URL, etc. to be included in the QR code. For example, when the detailed information is information related to a broadcast program, the detailed information may include a broadcast time, a main character (or cast member), a representative image (photo), a video, a plot, and the like of the broadcast program. When the broadcast program is a home shopping broadcast, the detailed information may include product price information, product code information, a product name, seller information, a seller related URL (uniform resource locator), a product description related URL, a product picture, a seller picture, and the like.

The processor 210 may be configured to process instructions of a computer program by performing input / output operations of the basic arithmetic, logic, and information providing system 200. The instructions may be provided to the processor 210 by the memory 240 or the network interface 230 and via the bus 220. The processor 210 may be configured to execute program codes for the code recognizer 211, the information extractor 212, the information determiner 213, and the information provider 214. Such program code may be stored in a recording device such as memory 240.

The code recognition unit 211, the information extracting unit 212, the information determining unit 213, and the information providing unit 214 may be configured to perform the steps 310 to 340 of FIG. 3.

In operation 310, the code recognition unit 211 may scan and recognize a QR code.

For example, the code recognizing unit 211 may recognize an image corresponding to the captured QR code by capturing a QR code using a camera mounted on the user terminal 101.

For example, while a user is watching a home shopping-related broadcast on a smart TV, or is watching a free broadcast content (movie, cartoon, etc.), a QR code related to the broadcast content (eg, a QR code including information related to a product on a home shopping broadcast) Or if the advertising QR code (eg, QR code for the next number of purchases of the broadcast program, QR code for the purchase of a broadcast program of the same category as the broadcast program, etc.) is displayed on the smart TV, the user terminal 101 is a camera (Not shown) can be used to shoot a QR code. Then, the code recognition unit 211 may recognize a QR code photographed through a camera (not shown).

In operation 320, the information extractor 212 may extract color information printed on the QR code from an image corresponding to the QR code. In this case, the information extractor 212 may extract color information from the center pixel of the finder pattern included in the QR code. For example, when there are three finder patterns in the QR code, color information may be extracted from the center pixel of each of the three finder patterns. Here, a detailed operation of extracting color information will be described later with reference to FIG. 5.

In operation 330, the information determiner 213 may determine channel information matching the extracted color information from the database. For example, when the extracted color information is R-R-R, the information determining unit 213 may determine the channel information corresponding to the QR code as channel 1 and when the color information is R-R-B, the channel information as channel 2.

In operation 340, the information provider 214 may display the determined channel information on the screen of the user terminal. The information provider 214 may read the information contained in the QR code and provide it to the user terminal by using a code recognition algorithm.

For example, the information providing unit 214 binarizes the QR code image using a ZXing (Zebra Crossing) algorithm, and performs a process of finding a finder in the binarized image to find the direction of the QR code. The information contained in the code can be read. For example, the information contained in the QR code is detailed information related to a broadcast program, and may include a broadcast time, a main character (or a cast member), a representative image (picture), a video, a plot, and the like of the broadcast program. When the broadcast program is a home shopping broadcast, the detailed information may include product price information, product code information, a product name, seller information, a seller related URL (uniform resource locator), a product description related URL, a product picture, a seller picture, and the like.

As described with reference to FIG. 3, color information of a QR code may include simple information related to a broadcast program, such as channel information, and detailed information related to a broadcast program may be included in an existing QR code.

4 is a diagram provided to explain a process of recording information using color information of a QR code according to one embodiment of the present invention. In FIG. 4, an example of dividing an area of a QR code into four parts will be described as an example. This corresponds to an embodiment, and the area of a QR code may be divided into two or more.

Referring to FIG. 4, the QR code 400 may include three finder patterns 401 and small square dots arranged in a matrix form. The finder pattern 401 is disposed at each of three corners of the QR code 400, and serves to provide directionality such that the QR code is recognized in any direction in 360 degrees. The square dots may include detailed information to be included in the QR code. In this case, the present invention may store simple information using the finder pattern 401.

For example, the area of the QR code may be divided into four based on the height and the length of the QR code 400. For example, the areas of the QR code may be divided into four quarters 402 such that the heights and lengths of the divided areas are the same. At least one color may be printed in each of the divided areas according to information to be included in the color information. For example, when the information indicating the channel 1 is to be recorded, the color of the R-R-R may be printed in each area based on the first upper right area 403 of the QR code 410. When information indicating channel 4 is to be recorded, red is printed in the first area 403, blue is printed in the second area 404, and red is printed in the third area 405. Can be.

FIG. 5 is a diagram illustrating an example of a QR code printed in color in one embodiment of the present invention.

Referring to FIG. 5, the first area 501 of the QR code 500 is printed in green, the second area 502 is printed in red, and the third area 503 is printed in blue. The fourth region 504 in which the finder pattern is not disposed may include only black and white colors as in the conventional QR code. Simple information represented by color information and detailed information such as an image, a video, and text are stored in the first to third areas, and only detailed information may be stored in the fourth area. In this case, the information extractor 212 may extract color information from the center pixel 505 of each finder pattern disposed in the first to third regions of the QR code.

For example, when the user is watching TV on a sofa having a distance of 3 m or more from the TV, the code recognizing unit 211 may recognize the QR code 500 displayed on the TV screen by photographing the camera of the user terminal. The information extracting unit 212 may find a finder pattern in the recognized QR code 500. The information extractor 212 may extract color information from the center pixel of the finder pattern. In this case, the information extracting unit 212 may extract color information from the finder pattern of the QR code based on the three sigma method. For example, the information extractor 212 may calculate an average value and a standard deviation value of colors represented by the color extracted from the center pixel. Table 1 below is a table illustrating an example of color information extracted from the third area Blue of FIG. 5.

Blue
R	G	B	B-R	B-G
30	32	153	123	121
20	25	151	131	126
19	27	152	133	125
10	24	146	136	122
18	35	165	147	130
38	33	179	141	146
39	37	183	144	146
39	37	182	143	145

Table 1 shows RGB values extracted from the center pixel 505 of the finder pattern disposed in the third region 503. According to Table 1, the information extractor 212 may calculate an average value and a standard deviation value of RGB values of the third region 503 (Blue). For example, the average value and the standard deviation value of the calculated third region may be as shown in Table 2 below.

Third area (B)	R	G	B	B-R	B-G
medium	36.40741	44.90741	180.3519	143.9444	135.4444
Standard deviation	28.29901	31.83247	35.36066	29.29569	27.10997

The information determiner 212 may calculate a three sigma value based on the calculated average value and standard deviation value. For example, the three sigma value may be calculated as shown in Table 3 below.

Third area (B)	-48	<R <	121
	-51	<G <	140
	74	<B <	286
	56	<B-R <	232
	54	<B-G <	217

The information determiner 212 may compare the three sigma values calculated as shown in Table 3 with the RGB values of the center pixels of the finder pattern matched to the third region 503. For example, when the average value of the third region falls within a range corresponding to three times the width of the standard deviation value, the information determiner 212 determines that the normal distribution follows the normal distribution, and the color extracted from the center pixel of the third region. The information can be finally determined in blue.

In the same manner, the information extracting unit 212 extracts color information from the center pixel of the finder pattern disposed in each of the second region 502 and the first region 501, and the information determining unit 213 performs a three sigma method. The color indicated by the extracted color information may be finally determined based on. For example, the first region may be determined to be green, and the second region may be determined to be red. In this case, when determining the red color, the information determining unit 213 may use RB and RG instead of BR and BG in Tables 1 to 3, and when determining the green color, the information determining unit 213 may use GR and GB. have.

As described above with reference to FIG. 5, the existing QR code has difficulty in recognizing the code at a short distance (for example, less than 2 m 90 cm), but the information providing system according to the present invention uses color information printed on the QR code. In addition, the QR code can be recognized even at a long distance (eg, more than 2m 90cm). For example, when a user watches TV on a sofa having a distance of 3 m or more (for example, a distance of 6 m and 5 cm between the screen displaying the QR code and the camera recognizing the QR code), the QR code displayed on the TV screen is displayed. It can be recognized through the user terminal. Then, the information providing system may provide the user with channel information matching the color information of the recognized QR code.

In this case, when the color information includes payment information of a product related to the broadcast being viewed, the information providing system may process an order and payment for the product by using the recognized QR code. And, at a short distance within a preset reference distance (eg, 2m 90cm), as in the conventional QR code recognition, detailed information contained in the QR code may be provided. For example, when photographing and recognizing a QR code near a TV, the information providing system may provide detailed information indicated by small square dots as well as simple information matching color information printed on the QR code. Here, although the payment information has been described as being included in the color information, this corresponds to an embodiment, and the payment information may be included in square dots of the QR code in addition to the color information.

6 is a diagram illustrating another example of a QR code printed with color information according to one embodiment of the present invention.

In FIG. 5, a case where RGB colors are printed in all three areas in which three finder patterns are arranged in a quarter-coded QR code is described. However, colors may be printed only in a part of areas not the whole three areas.

For example, as illustrated in FIG. 6, colors may be printed on the first finder pattern 601, the second finder pattern 602, and the third finder pattern 603 disposed in each of the first to third regions. In addition, the color may be printed only on the center pixel of each finder pattern. For example, a color representing simple information to be included in only the first center pixel 604 (green), the second center pixel 605 (red), and the third center pixel 606 (blue) may be printed. Then, the information extractor 212 extracts color information from the center pixel, and the information determiner 213 determines simple color represented by the extracted color information and matches simple information (eg, channel information) determined with the determined color information. Can be determined.

4 to 6 have been described for determining the simple information corresponding to the extracted color by extracting an RGB value from the center pixel of the finder pattern, this is the embodiment, the finder pattern of the QR code, and QR code In addition to the RGB color, a different color may be printed in each divided region of. For example, various colors such as pastel pink, sky blue, lemon, and light purple may be printed on the QR code, and as the number of colors to be printed increases, the amount of information that can be included in the color information of the QR code ( ^3K , K = Number of colors) may be increased.
