(Embodiment)
FIG. 1 is a diagram showing an example of a color code 1 in the present embodiment. In the figure, different diagonal lines indicate different colors.

  The color code 1 includes a code area 101 and a non-code area 102.

  The color code is, for example, a code in which an array of a plurality of colors is associated with arbitrary information. The information associated with the color code is, for example, an identifier. The color code may be referred to as a color barcode, for example. Information associated with the color code 1 can be obtained by reading the color code 1 with a color code reader 2 described later.

  The color code 1 is disposed on, for example, a sheet-like member such as paper or film, a product, or the like. For example, the color code 1 is printed on these members and products. The color code 1 may be displayed on a display device (not shown).

  The code area 101 is an annular area in which a plurality of cells 1012 having a plurality of colors arranged in an annular form of one or more rows are arranged. A plurality of cells having a plurality of colors are a plurality of cells each having one of a plurality of colors. The cell here is usually an area filled with a single color. The plurality of colors are, for example, 2 or more, preferably 3 or more, excluding the background color of the code area 101. The background color of the code area 101 does not matter. As the background color, for example, an achromatic color such as black or white is used. It goes without saying that the plurality of cells 1012 of a plurality of colors may have overlapping color cells 1012. The plurality of cells 1012 having a plurality of colors may be hereinafter referred to as a plurality of cells 1012 having a plurality of colors.

  The term “annular” here is usually circular, but it may be substantially circular, elliptical, polygonal, or the like. The plurality of cells 1012 arranged in two or more rows are, for example, a plurality of cells 1012 arranged along two or more rings that are concentric circles. Each cell 1012 has, for example, a fan-like shape obtained by radially dividing a belt-like ring. However, the shape, size, etc. of each cell 1012 do not matter. For example, the width of the row of cells 1012 arranged in a ring shape is not limited. The number of cells 1012 in each column may be the same or different. The plurality of cells 1012 may be arranged in a ring as long as the plurality of cells 1012 are arranged along the ring, whether adjacent cells 1012 are in contact with each other or not in contact with each other. good. For example, the adjacent cells 1012 may be arranged at a certain interval. Two or more rings in which the cells 1012 are arranged may be in contact with each other or may not be in contact with each other.

  For example, in the color code 1, an array of a plurality of color cells 1012 arranged in a ring in the code area 101 is associated with arbitrary information in advance, and this array is obtained by acquiring this array. It is possible to acquire the attached information. The number of patterns in the array of cells 1012 varies depending on the number of rows of rings arranged, the number of cells in each ring, and the number of types of cell colors. The number of columns in the code area 101, the number of cells in each ring, the type of cell color, and the like may be appropriately selected according to the amount of information associated with the color code.

  In FIG. 1, as an example, a case where three rows of rings 1011 a to 1011 c configured by arranging a plurality of cells 1012 is arranged in the code area 101 is shown. Here, it is assumed that, for example, 16 cells 1012 are arranged at equal intervals in each of the rings 1011a to 1011c.

  The non-code area 102 is an area inside the annular code area 101. Array attribute designation information 1021 is arranged in the non-code area. The array attribute designation information 1021 is information indicating the array attribute information. The array attribute information is information indicating attributes relating to the array of the cells 1012 of a plurality of colors arranged in the code area 101. For example, the array attribute information includes at least one or more of the number of columns of cells arranged in a ring arranged in the code area 101, the number of cells in each column, and the color type of cells that can be arranged in the code area. It is information to show. The color types of cells that can be arranged may be considered as all types of colors that can be arranged. The number of cells in each column indicated by the array attribute information may be the number of cells for each column, or may be a common number of cells when the number of cells in each column is the same. The number of rows of colored cells arranged in a ring may be considered as the number of rings formed of a plurality of cells, for example.

  The array attribute designation information 1021 may be the array attribute information itself or an identifier composed of a character string or the like associated with the array attribute information. The characters here are concepts including numbers. The array attribute designation information 1021 is, for example, a character string such as “number of columns: 3, number of cells: 16, number of colors: 8” when this information is the array attribute information itself. Alternatively, information such as “3: 16: 8” in which values of the number of columns, the number of cells, and the number of colors are arranged in a predetermined order may be used. Further, when the array attribute designation information 1021 is an identifier associated with the array attribute information, this identifier, for example, “ID123456” may be arranged in the non-code area 102. In this case, for example, one or more pieces of information associated with the identifier that is the array attribute designation information and the array attribute information are stored in advance in a storage unit (not shown) of a device (not shown) that reads the color code. Thus, the sequence attribute information corresponding to the code read from the non-code area 102 may be acquired from the storage unit by searching or the like as appropriate. The array attribute designation information may be an image recognizable by pattern matching or the like, such as a symbol or mark such as a star or a circle.

  The reference line segment 103 is a line segment for specifying a position serving as a reference for reading arranged so as to cross the row of the color cells 1012 arranged in the code area 101. The reference line segment 103 is, for example, a line segment extending toward the center of the rings 1011 to 1011c. Here, the reading reference is a position serving as a reference when reading information from the code area 101. For example, a cell 1012 having a positional relationship designated in advance with respect to the position where the reference line segment 103 is arranged becomes a reading reference, for example, a cell such as a start position or a head. For example, the cell 1012 closest to the reference line segment in the clockwise direction with the center of the rings 1011a to 1011c as the center of rotation is the reading start position or the first cell of each column. The reference line segment 103 is normally arranged at a position indicating a reading start position or an end position in a row of color cells arranged in a ring in the color code area. However, for example, a cell that is a predetermined number of cells apart from the reference line segment 103 may be determined as a reference cell, and a cell at a position rotated by a predetermined angle from the reference line segment 103 is read. It may be determined that the cell is a reference cell.

  The reference line segment 103 preferably has a display mode that can be identified with respect to a portion other than the reference line segment 103 such as the background of the cell 1012 or the code area 101. The display mode is, for example, a color, a pattern, a shape, or the like. For example, the reference line segment 103 may be a line segment of a color different from the cell 1012 or the background, may have a pattern such as a dot pattern, or has a shape such as a wavy line or a broken line. May be. Here, it is assumed that the reference line segment 103 has, for example, a color that can be used for the cell 1012 and a color different from the background color of the code area 101.

  FIG. 2 is a block diagram showing the configuration of the color code reader 2 for reading the color code 1.

  The color code reading device 2 includes an image acquisition unit 201, an array attribute information acquisition unit 202, a color code information acquisition unit 203, and a color code output unit 204.

  The color code reader 2 can be realized by, for example, a personal computer, a tablet terminal, a mobile phone, a so-called smartphone, a multi-function mobile phone, a mobile information terminal, a scanner, a camera, a dedicated terminal, or the like.

  The image acquisition unit 201 acquires an image obtained by capturing the color code 1 using an imaging unit such as a camera (not shown). The acquired image is a color image. The acquired image is usually a still image, but may be a moving image. The image acquisition unit 201 may acquire images obtained by photographing a plurality of color codes 1. The image acquisition unit 201 may or may not include an imaging unit, and may use an external imaging unit.

  The array attribute information acquisition unit 202 acquires array attribute information using the image acquired by the image acquisition unit 201. For example, the array attribute information acquisition unit 202 binarizes the image acquired by the image acquisition unit 201 and uses the binarized image to detect a part in which cells are arranged in a ring shape, and to the inside of the detected part Is detected as a non-code region 102. Then, the sequence attribute designation information 1021 is detected in the non-code area 102. For example, when the array attribute designation information 1021 is a character string, the character recognition technique used for OCR or the like is used to recognize the character and acquire the character string. You may think that the character here also contains a number. When the array attribute designation information 1021 is an image designated in advance, the image may be specified by image processing such as image pattern matching. Note that when the sequence attribute information acquisition unit 202 can directly detect the sequence attribute designation information 1021, the non-code area 102 need not be detected.

  Then, the array attribute information acquisition unit 202 acquires array attribute information corresponding to the acquired array attribute designation information 1021, for example. For example, an array stored in association with the same array attribute specification information as the above-obtained array attribute specification information from array attribute information stored in advance in association with the array attribute specification information 1021 in a storage unit (not shown) Get attribute information. If the array attribute specification information 1021 is the array attribute information itself, the process of acquiring the array attribute information associated with the array attribute specification information is omitted, and the array acquired by the character recognition technique, the image processing, or the like above. The attribute designation information may be acquired as array attribute information. For example, when the array attribute specification information 1021 is the array attribute information itself, the array attribute information acquisition unit 202 acquires the array attribute specification information from the image acquired by the image acquisition unit 201 and associates it with the acquired array attribute specification information. The process of acquiring the obtained array attribute information may be considered as a process in which the array attribute information acquisition unit 202 acquires the array attribute designation information that is the array attribute information using the image acquired by the image acquisition unit 201.

  The color code information acquisition unit 203 acquires information associated with the color code 1 using the array attribute information acquired by the array attribute information acquisition unit 202. The information associated with the color code 1 may be any information such as an identifier associated with the color code 1, and the same information as the information that can be associated with the normal color code can be associated. is there. The information associated with the color code 1 may be considered as information associated with the color cell array of the code area 101 of the color code 1, for example. To give a specific example, the color code information acquisition unit 203 acquires an array of color cells from the code area 101 using the array attribute information, and acquires information associated with the acquired array of color cells. . Obtaining an array of color cells means obtaining an array of color cells from a row of one or more color cells arranged in a ring in the code area 101. To acquire the array is, for example, to acquire information indicating an array of color cells, and specifically, to acquire information indicating how the cells of which color are arranged. . Obtaining an array means, for example, obtaining a plurality of combinations of cell colors and information indicating the positions where the cells are arranged. Here, the information indicating the position where the cells are arranged includes, for example, the arrangement order from the cell serving as the reference of reading indicated by the reference line segment 103 and the like, the arrangement order and the column of the ring where the cells are arranged. Or a combination thereof. The color code information acquisition unit 203 detects the reference line segment 103 from the image acquired by the image acquisition unit 201 as described above, and acquires an array of color cells based on the reference line segment. For example, the cell colors are sequentially acquired from each column in the clockwise direction from the position of the reference line segment 103. The reference line segment 103 is detected by searching for a line segment of the same color, for example, using information on the display mode of a reference line segment designated in advance. For example, color detection from each cell is performed for each column arranged in a ring shape. The information associated with the color code 1 is information indicating the arrangement of the color cells in the code area 101 of the color code 1, for example, information indicating the color of a plurality of cells and the position where each cell is arranged. Or a combination thereof.

  A configuration for acquiring a cell array from a plurality of cells arranged in a ring and a configuration for acquiring information associated with the acquired cell array of colors are known in the above-described prior art and the like. Therefore, detailed description is omitted here.

  Here, for example, in the present embodiment, the array attribute information acquired by the array attribute information acquisition unit 202 knows the number of columns of cells in the code area 101, the number of cells, and the types of colors that can be used. Therefore, it is possible to know in advance what color code 1 the color code 1 is, that is, what color code 1 is a combination of the number of columns, the number of cells, and the type of color used in the cells. That is, it may be considered that the code system of the color code 1 taken can be known. Therefore, even if the color code 1 is not known in advance, the color code information acquisition unit 203 determines the color code 1 attribute, that is, what color code 1 the color code 1 is. Can be known without judging from the cell arrangement status and the like, and by reading the color code according to the attribute of the color code 1, information can be read accurately and quickly from the color code 1. be able to. Further, since the attribute of the color code 1 is known, for example, the information is read from the code area 101 from the information of the cell arrangement pattern corresponding to the attribute of the color code 1 stored in advance in a storage unit (not shown). By detecting an array pattern that matches the array of cells, information corresponding to the detected array pattern, such as an identifier, can be acquired as information read from the color code 1. As a result, even if the color code 1 has different attributes, information corresponding to the cell array can be acquired appropriately.

  Further, since the attribute of the color code 1 is known in advance from the array attribute information, for example, it is possible to determine whether or not the cell array read by the color code information acquisition unit 203 is appropriate. Become. For example, if the read cell array indicates that there are 2 columns × 15 cells, and the color code 1 attribute acquired from the array attribute information indicates 2 columns × 16 cells, the two match. Therefore, it may be determined that there is an error in reading the color cell. This makes it possible to read the cell array with high accuracy.

  The color code output unit 204 outputs information associated with the color code 1 acquired using the color code 1 acquired by the color code information acquisition unit 203. The information associated with the color code 1 is, for example, an identifier associated with the color code. The determination result of the color code 1 is information associated with the color code read from the color code 1, for example.

  The output here includes display on a display, projection using a projector, printing on a printer, sound output, transmission to an external device, storage in a recording medium, processing to another processing device or other program, etc. It is a concept that includes delivery of results.

  The color code output unit 204 may or may not include an output device such as a display or a printer. The output unit may be realized by output device driver software, or output device driver software and an output device.

  When a plurality of color codes 1 are captured in the image acquired by the image acquisition unit 201, for example, the above-described processing may be sequentially performed for each color code 1.

  Hereinafter, an example of a specific operation of the process of reading the color code 1 in the present embodiment will be described. Here, it is assumed that the color code reader 2 is a tablet terminal with a camera. Here, a case where the array attribute designation information 1021 arranged in the non-code area 102 of the color code 1 is an identifier associated with the array attribute information will be described.

  FIG. 3 is a diagram showing array management information having array identifiers and array attribute information associated with each other. It is assumed that the array management information is stored in advance in a storage unit (not shown) of the color code reader 2. The array management information has attributes of “array ID” and “array attribute”. “Array ID” is array attribute designation information. “Array attribute” indicates array attribute information. In the attribute value of “array attribute”, “line:” is the number of cells arranged in a circle, “cell:” is the number of cells arranged in each column, and “color:” is available for the cell. All color types are shown.

  As shown in FIG. 4A, as a result of photographing the color code 1 shown in FIG. 1 with the camera 2011 of the color code reader 2, the image acquisition unit 201 acquires an image as shown in FIG. 4B. Suppose that The array attribute information acquisition unit 202 acquires the array identifier “CID001” by character recognition from the non-code area 102 of the image acquired by the image acquisition unit 201. Then, from the array management information shown in FIG. 3, a record (row) whose “array ID” matches “CID001” acquired from the image is detected, and the attribute value of “array attribute” of the detected record is acquired. . It is assumed that the acquired attribute value is “line: 3; cell: 16; color: red, blue, green, yellow ...”.

  The color code information acquisition unit 203 acquires information associated with the color code 1 using the array attribute information acquired by the array attribute information acquisition unit 202. Specifically, the reference line segment 103 is detected from the image acquired by the image acquisition unit 201, and an array of cells of the color of each column of the code area 101 is acquired from the position of the detected reference line segment 103, and acquired. Obtain information associated with an array of color cells.

  Here, as described above, since the attribute of the color code 1 is known in advance from the array attribute information, the color code information acquisition unit 203 does not specify the attribute of the color code 1 before the image is captured. However, the color cell array can be accurately and quickly acquired from the code area 101.

  The color code output unit 204 outputs information associated with the color cell array acquired by the color code information acquisition unit 203. For example, when the product identifier is associated with the color cell array in advance, the color code output unit 204 outputs the product identifier corresponding to the color code 1.

  As described above, according to the present embodiment, the arrangement attribute designation information is arranged in the non-coding area that is not used for reading the color code, so that the non-coding area can be effectively used and further arranged in the non-coding area. The accuracy and speed of color code reading can be improved using the array attribute information acquired from the array attribute designation information. In addition, even color codes with different attributes and different code systems can be read quickly and accurately, and color codes with different attributes can be used in a seamless mixture. Versatility can be improved.

  In the first embodiment, the array attribute information is arranged in the non-code area 102. However, in the present invention, the non-code area is used instead of or in addition to the array attribute information. A logo may be arranged at 102. The logo is, for example, a design character such as a company name or a product name. The logo may be a mark indicating a company, organization, product, service, or the like.

  FIG. 5 is a diagram showing a modification of the color code 1 in which a logo is arranged.

  As shown in FIG. 5, by arranging the logo 1022 in the non-code area 102, the user can visually identify the owner or user of the color code. In addition, the non-code area 102, which is an area where no color cell is arranged, can be used effectively.

  In the above embodiment, each component of the color code reader 2 may be configured by dedicated hardware, or the components that can be realized by software may be realized by executing a program. Good. For example, each component can be realized by a program execution unit such as a CPU reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory. At the time of execution, the program execution unit may execute the program while accessing a storage unit (for example, a recording medium such as a hard disk or a memory).

  The software for realizing the color code in the above embodiment is the following program. That is, this program acquires the array attribute designation information from the image obtained by the image acquisition unit that acquires the image of the color code described in the above embodiment and the image acquisition unit, and the acquired array attribute designation information.

  In the program, the functions realized by the program do not include functions that can be realized only by hardware. For example, a function that can be realized only by hardware such as a modem or an interface card in an acquisition unit that acquires information or an output unit that outputs information is not included in the function realized by the program.

  Further, the computer that executes this program may be singular or plural. That is, centralized processing may be performed, or distributed processing may be performed.
