example 1

[0020] Example one: in the encoding process of concrete implementation, at first the N of described A step is tentatively set as 4, represents that one pixel can represent 4 bits, i.e. 16 kinds of colors, 16 kinds of color correspondence tables are set here, as [OX0= C0, OX1=C1, OX2=C2 . . . OXF=C15]. There are 8 kinds of mask values ​​described in step A, which is based on the fact that 3 bits in the format information represent the mask index value, ie. These 8 kinds of mask values ​​[OX0=S0, OX0=S1, OX0=S2...OX8=S8] are set here, the offset amount described in the A step is made of A1, A2, and this is because the colored area is composed of Area A1 and Area A2 constitute. Here select their offset [A1=01, A2=02]. Finally, enumerate all the version numbers and the number of bytes of the relevant error correction data and the number of data bytes described in the A step, [[V1[L EC=4[D=12]][M EC=6[ D=10]][Q EC=8[D=8]][H EC=10[D=6]][V2[LEC=8[D=24]][M EC=12[D=20] ][Q EC=16[D=...

Abstract

The invention relates to the field of information encoding and provides a CCQR (Colorful Coded Quick Response) code encoding method and a CCQR code decoding method. CCQR codes are a kind of novel graphic-symbol automatic recognizing, reading and processing quick-response codes which are based on a computer image processing technique, a combined encoding principle and the like. The encoding method is a CCQR code generation method which comprises the steps of setting an offset, a mask value and a color corresponding table for a color area, selecting information data, filling the color area and a black-white area, loading a functional graphic, edition information and format information, and the like. The decoding method is a CCQR code recognizing and reading method which comprises the steps of setting a corresponding table for the color area, positioning and unitizing the CCQR codes according to the same method for QR (Quick Response) codes, removing the mask of the black-white area, correcting errors, removing the mask of the color area, correcting errors, and the like. The CCQR code encoding method and the CCQR code decoding method have the beneficial effect that a realization method is provided for generation, recognition and reading necessary for using the CCQR codes for an anti-counterfeiting purpose in combination with the advantages of quick and accurate recognition of the QR codes and by using the anti-counterfeiting characteristics in the color area.

Description

technical field [0001] The invention belongs to the field of information coding and provides a practical and effective method for the field of anti-counterfeiting. Specifically, it is a multi-area encoding method with black and white plain codes in two areas and color codes in one area. The invention relates to a method for generating a CCQR code, and also relates to a method for reading the CCQR code generated by the above-mentioned generating method. Background technique [0002] At present, the widely used QR code is a two-dimensional space bar code, and the QR code uses two colors of dark color and light color to fill the entire graphic. This feature makes it easy to be imitated, and it is not suitable for anti-counterfeiting. [0003] In addition, the invention of Color Code is the representative of the third-generation barcode technology in the world. The color code determines the colors in black, blue, green and red, so that different color codes can be printed quic...
