[0005] Identification codes such as barcodes and QR codes are used for many purposes, but due to restrictions on how they are displayed (display conditions), the amount of information that can be added to a single code is limited. There was also a demand to increase the total number of identification codes in order to accommodate an increase in the amount of information that can be added when used under the same conditions (constraints) and to accommodate not only identification codes displayed on printed materials, but also optical signal applications (display display) in information processing within computers. [Means for solving the problem]

[0006] (1) Identifying "color (multi-color) identification codes" using "a code reader using an image sensor camera" Conventional identification codes such as barcodes and QR codes are displayed in monochrome (two colors), but these will be displayed in color (multiple colors). In the case of an identification code that uses multiple colors, a single identification code can be read in multiple ways by setting a specific color and the other colors to a binary number (0 and 1), determining the order of each color, and reading them in that order. This combines multiple monochrome (two-color) display codes into one color (multi-color) display code, making it possible to provide more information with the same identification code display. This color (multi-color) code cannot be converted into a digital signal using conventional code readers such as infrared sensors and program software, so a camera-type code reader that uses an image sensor (image pickup element) that can distinguish multiple colors and corresponding program software is used to convert it into a digital signal. (2) Identifying the "identification code of the arrangement of numbers, letters, etc." using a "code reader using a camera with an image sensor" Conventional identification codes such as barcodes and QR codes are displayed in monochrome (two colors), but this will be replaced by an arrangement of numbers and letters. (The arrangement of two colors, black and white dots and lines, will be replaced by an arrangement of numbers and letters.) For example, in the case of an identification code consisting of multiple numbers, by setting certain numbers and the remaining numbers to be binary (0 and 1), and then determining the order of each number and reading them in that order, it becomes possible to read a single identification code in multiple ways. This combines multiple monochrome (two-color) display codes into a display code with a single number, making it possible to add more information to the same identification code display. These positional display codes, which consist of numbers and letters, cannot be converted into digital signals using conventional code readers such as infrared sensors and program software, so they are converted into digital signals using a camera-type code reader that uses an image sensor (image sensor) that can identify shapes and corresponding program software. (3) The "3D identification code" is identified using a "code reader using a laser light transmission and reception camera." Conventional identification codes such as barcodes and QR codes are displayed in two dimensions in monochrome (two colors), but this will be displayed in three dimensions in one color. In the case of an identification code with multiple heights (bumps) in three dimensions, specific heights and other heights are set to binary (0 and 1), and the order of each height is determined and read in that order, making it possible to read one identification code in multiple ways. This combines multiple two-dimensional monochrome (two-color) display codes into one three-dimensional single-color display code, making it possible to add more information to the same identification display code. This three-dimensional monochrome display code cannot be converted into a digital signal using conventional code readers such as infrared sensors and program software, so it is converted into a digital signal using a laser light transmitting and receiving camera type code reader and corresponding program software that can identify three-dimensional information (shape). The problem is solved using methods (1), (2), and (3).

Claims

1. Identification codes that use barcodes, QR codes, etc. have information attached to a monochrome (two-color) code that is read by a dedicated device (infrared sensor code reader, smartphone camera, etc.) and converted into a digital signal by the device's program. (The two-color display is converted to digital by converting it into a binary number of 0 and 1). By displaying this in full color (multiple colors) instead of monochrome (two colors), more information can be added to the same code display. Conventionally, binary numbers (0 and 1) were displayed in two colors, but by displaying this in six colors, it is possible to set multiple binary numbers (0 and 1) in one code by assigning a reading order to the colors used. For example, in the case of a six-color display, the colors are read in a predetermined order: (1) red, (2) orange, (3) yellow, (4) green, (5) blue, and (6) purple. (1) Set red and other colors as binary (0 and 1). (2) Set orange and other colors as binary (0 and 1). After setting all the colors to be displayed in this manner, (1) through (6) are read in order. Furthermore, if we group the colors as follows: (7) red and orange, (8) yellow and green, and (9) blue and purple, then (7) red, orange, and the other colors are set as binary numbers (0 and 1). In this case, information can be added in nine different display (reading) methods with one code. Conventional monochrome (two-color) display code reading devices (such as infrared sensor code readers) cannot read full-color (multi-color) display codes, so they are read using a device that can distinguish multiple colors, such as a camera that uses an image sensor (imaging element). This full-color identification code is identified by a reading device equipped with an image sensor, thereby adding more information to one identification code. A method of adding more information by using the differences in multiple colors used in one identification code to set multiple ways of reading binary numbers (combinations of 0 and 1).

2. Identification codes that use barcodes, QR codes, etc. have information attached to a monochrome (two-color) code that is read by a dedicated device (infrared sensor code reader, smartphone camera, etc.) and converted into a digital signal by the device's program. (The two-color display is converted to digital by converting it into a binary number of 0 and 1). By displaying numbers, letters, symbols, etc. instead of monochrome (two-color) display, more information can be added to the same code display. Conventionally, binary numbers (0 and 1) were displayed using two colors, but by using a display that arranges numbers, letters, symbols, etc., it is possible to set up multiple binary numbers (0 and 1) in one code by assigning a reading order to the number (type) of numbers, letters, symbols, etc. used. (Using numbers, letters, symbols, etc. to display the identification code means, in the case of a barcode, writing numbers, etc. vertically instead of vertical lines (bars), and in the case of a QR code, writing numbers, etc. instead of black and white dots.) For example, if you want to display numbers from 0 to 4, you can read them as 0, 1, 2, 3, 4. You can then decide on the order in which the numbers will be displayed and read them in that order. (1) Set the number 0 and other numbers as binary (0 and 1). (2) Set the number 1 and other numbers as binary (0 and 1). In this way, after setting all the numbers to be displayed, they are read in order. In this case, information can be added in five different display (read) methods with one code. Conventional monochrome (two-color) display code reading devices (such as infrared sensor code readers) cannot read display codes that contain numbers, letters, symbols, etc., so they are read by devices that can distinguish differences in the shapes of numbers, letters, etc., such as cameras that use image sensors (imaging elements). This method adds more information to one identification code by identifying the identification code, which is made up of numbers, letters, symbols, etc., with a reading device equipped with an image sensor. A method of adding more information by taking advantage of the differences in the numbers and letters used in a single identification code and setting up multiple ways to read the binary code (combinations of 0 and 1).

3. Identification codes such as barcodes and QR codes have information attached to monochrome (two-color) displayed codes that is read by a dedicated device (infrared sensor code reader, smartphone camera, etc.) and converted into a digital signal by the device's program. (The two-color display is converted to digital by converting it into a binary number of 0 and 1). By displaying this in three-dimensional single color rather than two-dimensional monochrome (two-color) display, it is possible to add more information to the same code display. Conventionally, binary numbers (0 and 1) were displayed by the difference between two colors in two dimensions, but when this is made into a three-dimensional monochrome display, the binary numbers (0 and 1) are displayed by the difference in height of the bumps rather than by color, and by assigning a reading order to the difference in height, it is possible to set up one code so that multiple binary numbers (0 and 1) can appear. For example, if the lowest point in a three-dimensional display is 0 mm and the highest point with a difference of 1 mm is 4 mm, then it will be displayed in five different heights from 0 mm to 4 mm, and it is decided to read them from the lowest, and they will be read in order. (1) Set the height to 0 mm or other heights as binary (0 and 1). (2) Set the height to 1 mm or other heights as binary (0 and 1). In this way, the total height to be displayed is set, and the five levels are read in order. In this case, information can be added in five different display methods (reading methods) with one code. Conventional devices for reading two-dimensional monochrome display codes (such as infrared sensor code readers) cannot read three-dimensional display codes, so they are read using a device that can identify three-dimensional information, such as a laser light transmitting and receiving camera. (A laser light transmission / reception camera is a device that obtains three-dimensional information about an object by irradiating (transmitting) a laser light at the object and receiving the reflected light.) When a laser beam is shone onto the entire three-dimensional display code, the three-dimensional information of the code can be read based on the time difference between when the reflected light is received. This method adds more information to one identification code by identifying the three-dimensional identification code with a laser light transmitting and receiving camera type reader. A method of adding more information by taking advantage of the differences in height (convex and concave) used in a single identification code and setting multiple ways of reading the binary code (combinations of 0 and 1).
