It is as follows：Include the mask version of line number, columns, version information, error-correction level and data message.Generate format version information code word
Sequence.
Reliability when mask information is to improve recognition code is added in Quick Response Code code figure, and avoids the formation of correction
The bit stream of regional function module.Handled by following step, the purpose of mask can be met.
A, mask process is not used to functional graphic；
B, data message is subjected to xor operation with designing specific 8 mask graphs；
C, each result, the selection wherein best figure of effect are assessed.
The functional graphic includes rim area, clear area, positioning area and correction zone.
Finally, processing, generation data message code area, to the form are masked to the data message codeword sequence
Version information codeword sequence is masked processing, generation format version information area
Fig. 4 is the particular flow sheet of the generation Quick Response Code according to the utility model embodiment, as shown in figure 4, first, using
Person's input coding information first, whether system automatic decision is beyond the maximum version capacity of Quick Response Code；System is entered to data afterwards
Row analysis, enter row information coding from suitable coded system, and suitable version and error correction are selected according to the size of information content
Pattern；Followed by the coding of data message, data bit stream is formed, and piecemeal is carried out according to corresponding version；For each
The data bit stream of block, corresponding error correction code word is generated by RS algorithms；Error correction code word is added after code word data sequence, is formed
The codeword sequence finally given, including generation data message codeword sequence and format version information codeword sequence, and inserted
Blank code figure；Format version information and corresponding error correction information are finally respectively implanted on three angles and is masked；It is finally right
The data message codeword sequence of input is masked.
Fig. 5 is the decoding particular flow sheet of the Quick Response Code according to the utility model embodiment, as shown in figure 5, Quick Response Code
Coding/decoding method is summarised as below scheme：
(1) in the decoding process of Quick Response Code, rim area positioning and identification code schematic symbol image are passed through first；
(2) format version information is distinguished (to remove mask and complete the error correction of format information, identify error-correction level and mask artwork
Shape), version information is distinguished afterwards, determines the version of symbol；
(3) bitmap of coding region is carried out with mask graph xor operation remove mask (before mask graph from
Drawn in format information)；
(4) according to module array rule, sign character is distinguished, recovers information data and error correction code word；
