Moth-eaten colored QR code

Abstract

We provide a QR Code (registered trademark) that can be visually distinguished and has value as a work of art. [Solution] Colored QR codes have data bits in red, blue, yellow, etc., and data cells other than data bits in green, white, etc., for the purpose of making them easier to see and turning them into works of art. The content can be compared and judged visually, and they are recognized as works of art, which also helps to deter crime.

Description

[Technical field]

[0001] QR codes (the QR code is a registered trademark of DENSO WAVE) that are affixed to products in supermarkets and other stores were developed with the aim of making it easy to read product information. Later, it became possible to "read QR codes using a smartphone camera," expanding their value. [Background technology]

[0002] Other types of two-dimensional codes include barcodes and color codes. Color codes have 50 times the discrimination ability of QR codes, and there are efforts underway to differentiate them from QR codes in the future. However, most of the color codes are used by companies with ample financial resources, and personal use is limited. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 2938338 Two-dimensional code [Patent Document 2] Patent No. 7555509 Coloring of QR Codes Summary of the Invention [Problem to be solved by the invention]

[0004] The prior art document "Coloring of QR Codes" does not include the claims Claim 1 describes a QR code characterized in that, for the purpose of facilitating visual comparison, a two-dimensional code arranged as a pattern on a two-dimensional matrix has a number data cell, an alphanumeric data cell, an image, a sound data cell, a kanji data cell, a katakana data cell, and a hiragana data cell of the data pattern colored in red, and a positioning symbol, a timing cell, a vertex detection cell, an error correction word, a filler code word, a filler bit, a residual bit, a residual code word, and a residual pattern colored in black, and a three-color pattern arranged on a matrix of basic colors. Claim 2 states that the QR code is characterized by the fact that, for the purpose of facilitating visual comparison and discrimination, the two-dimensional code is arranged as a pattern on a two-dimensional matrix, and that the data pattern has four types of data cells, namely, numeric data cells, alphanumeric data cells, image and sound data cells, kanji, katakana, and hiragana data cells, each of which has a different colored bit, and that the positioning symbol, timing cell, apex detection cell, error correction word, filler code word, filler bit, residual bit, residual code word, and residual pattern are colored black, and that a six-color pattern is arranged on the matrix, which is the basic color. When actually creating QR codes, the majority of companies' QR codes use English letters and numbers, and the black cells other than the data cells are ugly. [Means for solving the problem]

[0005] There are four modes to choose from when creating a QR code. The QR code can be made into a QR code according to the indicators using four types of character data: numeric data (maximum 7,089 characters, indicator 0001), English data (maximum 4,296 characters, indicator 0010), 8-bit byte data (maximum 2,953 characters, indicator 0100), and Kanji data (maximum 1,817 characters, indicator 1000). To make the QR code easier to see, the four types of characters used in the QR code are colored individually, the other cells are colored a different color, and the blank spaces within the dots are colored the basic white color of the matrix. This gives the QR code of this invention a vibrant appearance with at least six or more colors, making it possible to determine its content and distinguish it from illegal QR codes, and it will also be recognized as a work of art. Effect of the Invention

[0006] The QR code of the present invention makes it possible to judge the content and distinguish it from illegal QR codes by using the contrast between each of the dark multi-colored data cells and the spaces within the dots, which is useful for crime prevention. It can also be recognized as an art QR code or quiz QR code, making QR code pattern recognition common, and it is also visually beautiful and colorful. [Brief description of the drawings]

[0007] [Figure 1] Image of a QR code in red, white, yellow, and green [Diagram 2] Image of a moth-eaten QR code in red, white, yellow, green, and navy blue DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] There are four modes to choose from when creating a QR code. Four types of characters can be converted into QR codes: numeric data, English data, 8-bit byte data, and Chinese character data. The characters to be used as QR codes are converted into a string of bits according to rules, and then a code word and an error correction code word are created. At this time, it is necessary to divide the data into blocks according to certain rules. Incidentally, in an Excel worksheet, each square in which numbers or letters are written is called a "cell," and a cell selected by clicking with the mouse is called an active cell. By clicking with the mouse to select a cell (making it an active cell), the cell becomes ready to be filled with letters, numbers, or formulas. Furthermore, a bit is a unit of information, and one bit is the amount of information that allows one of two things to be obtained with equal probability, and is a number or code used in the binary system. Each data code word is divided into n RS blocks, and an error correction code word is calculated for each block of the divided data code words, and data words and error correction words are taken from each RS block in order to construct the final column. The data words and error correction code words of the core block are arranged according to certain arrangement rules. A mask processing pattern is applied to the symbol coding area, and the mask with the lowest loss of points out of the eight mask patterns is selected based on a certain evaluation standard. Format information and model number information (appears in model numbers 7 and above) are added, and finally the QR code is completed. In simple terms, the data is set and binary coded, then CRC (a function that detects errors in data) is added, an error correction code is added, a two-dimensional arrangement is performed, and an exclusive OR (an XOR circuit that considers only true when one of two propositions is true, where current flows and false when it does not) is performed with a matrix pattern for changing cell characteristics (a structure or diagram in which two or more elements are arranged on a board), the optimal arrangement is detected and placed in a two-dimensional code, and the data is sent to a host computer (not shown), and the host computer performs the specified control based on this data. EXAMPLES

[0009] Figure 1 shows an image of a QR code (1) colored in red, yellow, green, and blank spaces for data cells (5) created by coloring in green the cells other than the data cells (4), such as the red numeric data cells (6), the yellow English data cells (7), and the three positioning symbols (2), timing cells (3), and the apex detection cells, error correction words, filler code words, filler bits, residual bits, residual code words, and residual pattern apex detection cells. The QR code is also colored in red, yellow, green, and blank spaces for data cells (5). The blank spaces are then colored in green to create a matrix of basic colors (8). EXAMPLES

[0010] Figure 2 shows a conventional QR code created by mixing data cells such as positioning symbols, timing cells, vertex detection cells, error correction words, filler code words, filler bits, residual code words, and residual patterns with bits other than data cells, which are arranged as a pattern on a two-dimensional matrix using 8-bit byte data indicators for data cells of numeric data cells, alphabet data cells, image data cells, sound data cells, kanji data cells, hiragana data cells, and katakana data cells. The QR code is created by recognizing the yin-yang pattern of light and dark and removing the back color, and the cells that were previously written in black in many QR codes are replaced with bits that have been changed to cells of any color that can be read by devices such as smartphones that have a reading function, and then arranged in a worm-eaten colored QR code (9) pattern on an artwork. EXAMPLES

[0011] Both the colored QR code (1) of Example 1 and the insect-eaten colored QR code (9) of Example 2 can include a company logo or other message by utilizing the capabilities of a smartphone or other device that has a reading function that can fill in the missing parts. EXAMPLES

[0012] In both the colored QR code (1) of Example 1 and the wormhole-colored QR code (9) of Example 2, the colors of the cells used for the bit groups can be freely chosen and changed as art without any particular designation as long as they react to devices such as smartphones. The colors of messages such as company logos that can be incorporated by utilizing the capabilities of smartphones and other devices with a reading function that fills in the missing parts can also be freely chosen.
