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

2, the information providing system 200 according to the present 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 recognition unit 211, an information extraction unit 212, an information determination unit 213, and an information provision unit 214. In other embodiments, the information providing system 200 may include more components than the components of FIG. 2, or some of the components may be omitted

The memory 240 may be a computer-readable recording medium and may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. Also, 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 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, or a memory card. In other embodiments, the software components may be loaded into the memory 240 via the network interface 230 rather than from a computer readable recording medium.

The bus 220 may enable communication and data transfer 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 (SAN), 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 the computer network via a wireless or wired connection.

The database 250 is constituted by a code scan application, and plays a role of matching and storing the information combined with the color information printed in the QR code and the channel information.

For example, in the case where an RGB (Red Green Blue) color is printed on the QR code, the database 250 can store and maintain information represented by a combination of RGB colors. For example, color combination information and channel information may be matched and stored such as RRR for channel 1, RRB for channel 2, RRG for channel 3, RBR for channel 4, and the like. In this case, when three colors are used in the QR code, 3 3 = 27 pieces of 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 can be matched and stored. If K colors are used, 3 K color combination information is matched with channel information and stored .

Here, it is assumed that the channel information is stored in the database 250 by matching with the color combination information, but it corresponds to the embodiment. In addition to the channel information, the simple information is matched with the color combination information and is stored and maintained in the database 250 . For example, as the simple information, a broadcasting program name, a broadcasting company (KBS, SBS, MBC, A home shopping, B home shopping, etc.) can be used.

The database 250 stores and maintains detailed information included in the QR code in association with the QR code. Here, the detailed information can represent various information such as an image, text, and URL to be included in the QR code. For example, when the detailed information is information related to a broadcast program, it may include a broadcast time of the broadcast program, a main character (or cast), a representative image (photo), a moving image, When the broadcast program is a home shopping broadcast, the detailed information may include product price information, product code information, product name, seller information, URL related to the seller (uniform resource locator), URL related to the product description, product photograph, seller photograph, and the like.

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

The code recognizing 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.

In step 310, the code recognition unit 211 can scan and recognize the QR code.

For example, the code recognition unit 211 can recognize an image corresponding to the photographed QR code by photographing the QR code using the camera mounted on the user terminal 101. [

For example, when a user is viewing a home shopping related broadcast on a smart TV or watching a free broadcast content (movie, cartoon, etc.), a QR code related to the broadcast content (e.g., a QR code including product- Or a commercial QR code (e.g., a QR code for the next number of purchases of a program being broadcast, a QR code for purchasing a program of the same category as the program being broadcast, etc.) is displayed on the smart TV, (Not shown) can be used to photograph the QR code. Then, the code recognition unit 211 can recognize the QR code photographed through a camera (not shown).

In operation 320, the information extracting unit 212 may extract the color information printed on the QR code from the image corresponding to the QR code. At this time, the information extracting unit 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 can be extracted from the center pixel of each of the three finder patterns. Here, the detailed operation of extracting the color information will be described later with reference to FIG.

In step 330, the information determination unit 213 may determine channel information matching with the extracted color information in the database. For example, when the extracted color information is R-R-R, the information determination unit 213 may determine the channel information corresponding to the QR code to be the channel 1, and may determine the channel information to be the channel 2 if the color information is R-R-B.

In step 340, the information providing unit 214 may display the determined channel information on the screen of the user terminal. The information providing unit 214 may read the information stored in the QR code using the code recognition algorithm and provide the information to the user terminal.

For example, the information providing unit 214 binarizes a QR code image using a ZXing (Zebra Crossing) algorithm, finds a finder in the binarized image, and finds a direction of the QR code. The information stored in the code can be read. For example, the information included in the QR code may be detailed information related to the broadcast program, including the broadcast time of the broadcast program, the main character (or cast), representative image (photo), moving image, plot, When the broadcast program is a home shopping broadcast, the detailed information may include product price information, product code information, product name, seller information, URL related to the seller (uniform resource locator), URL related to the product description, product photograph, seller photograph, and the like.

As described with reference to FIG. 3, the color information of the QR code includes simple information related to the broadcast program such as channel information, and detailed information related to the broadcast program may be stored in the existing QR code.

FIG. 4 is a view for explaining a process of storing information by using color information of a QR code according to an embodiment of the present invention. In FIG. 4, the case of dividing the area of the QR code into four equal parts is exemplified, but this corresponds to the embodiment, and the area of the QR code can be divided into two or more.

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

For example, based on the height and length of the QR code 400, the area of the QR code can be divided into four. For example, the area of the QR code may be quartered 402 such that the height and length of each divided area are the same. At least one color may be printed in each of the divided regions according to information to be included in the color information. For example, when it is desired to store information representing channel 1, the color of R-R-R may be printed in each area based on the upper right first region 403 of the QR code 410. (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 in order to record information indicating the channel 4 .

5 is a diagram showing an example of a QR code printed with hues in an embodiment of the present invention.

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. And the fourth area 504 in which the finder pattern is not disposed may include only black and white colors as in the conventional QR code. In the first to third areas, detailed information such as images, moving pictures, texts, and the like represented by the color information and the detailed information may be recorded in the fourth area. At this time, the information extracting unit 212 can extract the color information from the center pixel 505 of each finder pattern arranged in the first to third regions of the QR code.

For example, when a user is viewing a TV on a couch having a distance of 3 m or more from the TV, the code recognition unit 211 can recognize the QR code 500 displayed on the TV screen by photographing with the camera of the user terminal. The information extracting unit 212 can find the finder pattern from the recognized QR code 500. [ The information extracting unit 212 can extract color information from the center pixel of the finder pattern. At this time, the information extracting unit 212 may extract the color information from the finder pattern of the QR code based on the three sigma method. For example, the information extracting unit 212 may calculate an average value and a standard deviation value of a color represented by the color extracted from the center pixel. Table 1 below is a table showing an example of the color information extracted from the third area (Blue) in Fig.

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 area 503. According to Table 1, the information extracting unit 212 can calculate an average value and a standard deviation value of the RGB values of the third area 503 (Blue). For example, the calculated average value and standard deviation value of the third region may be as shown in Table 2 below.

The third region (B) R G B B-R B-G medium 36.40741 44.90741 180.3519 143.9444 135.4444 Standard deviation value 28.29901 31.83247 35.36066 29.29569 27.10997

The information determination unit 212 may calculate the 3-sigma value based on the calculated average value and the standard deviation value. For example, the 3 sigma value can be calculated as shown in Table 3 below.

The third region (B) -48 <R < 121 -51 <G < 140 74 <B < 286 56 <B-R < 232 54 <B-G < 217

The information determination unit 212 may compare the calculated 3-sigma value with the RGB values of the center pixel of the finder pattern matched with the third area 503 as shown in Table 3. [ For example, when the average value of the third region falls within a range corresponding to three times the standard deviation value, the information determination unit 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.

The information extraction unit 212 extracts color information from the center pixel of the finder pattern disposed in each of the second area 502 and the first area 501, The color represented by the extracted color information may be finally determined. For example, the first area may be determined to be green and the second area may be determined to be red. At this time, when determining red, the information determining unit 213 can use RB and RG instead of BR and BG in Tables 1 to 3. In determining the green color, the information determining unit 213 can use GR and GB have.

As described above with reference to FIG. 5, existing QR codes have difficulty in recognizing codes in 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 QR codes , And a QR code can be recognized even at a long distance (for example, 2 m 90 cm or more). For example, when a user watches a TV in a sofa having a distance of 3 m or more (for example, a screen displaying a QR code and a camera recognizing a QR code of 6 m 5 cm), a QR code displayed on the TV screen And can be recognized through the user terminal. Then, the information providing system can provide the user with channel information matching the color information of the recognized QR code.

At this time, if the color information includes payment information of a product related to the broadcast being viewed, the information providing system may process the order and payment for the goods using the recognized QR code. In a short distance within a predetermined reference distance (for example, 2 m 90 cm), the detailed information recorded in the QR code can be provided as in the conventional QR code recognition. For example, when the QR code is photographed near the TV and is recognized, the information providing system can provide not only simple information matching with the color information printed in the QR code, but also detailed information represented by small square dots. Here, the payment information is included in the color information, but this corresponds to the embodiment, and the payment information may be included in the square points of the QR code in addition to the color information.

6 is a diagram showing another example of a QR code in which color information is printed, according to an embodiment of the present invention.

In FIG. 5, RGB color is printed in all three regions in which the three finder patterns are arranged in the quadratic QR code. However, the color may be printed only in some of the three regions.

For example, colors may be printed on the first finder pattern 601, the second finder pattern 602, and the third finder pattern 603 disposed in the first to third regions, respectively, as shown in FIG. In addition, colors may be printed only on the center pixel of each finder pattern. For example, colors representing simple information intended to be contained only in the first center pixel 604, the second center pixel 605, and the third center pixel 606 may be printed. Then, the information extracting unit 212 extracts color information from the center pixel, and the information determining unit 213 determines the final color represented by the extracted color information, and outputs simple information (for example, channel information) Can be determined.

4 to 6, the RGB values are extracted from the center pixel of the finder pattern to determine the simple information corresponding to the extracted color. However, this corresponds to the embodiment, and the finder pattern of the QR code and the QR code Other colors may be printed in addition to the RGB colors. For example, various colors such as pastel tones such as pink, light blue, lemon, and light purple can be printed on the QR code. The amount of information (3 K , K = The number of colors) can be increased.
