140。
Adjusting apparatus 140, for when the reading device 130 can not to it is described generate mixing Quick Response Code include it is each
When Quick Response Code is identified, position relationship and size of the identified the multiple Quick Response Code in the preset template are adjusted
Relationship makes the bit error rate for generating mixing Quick Response Code be less than error correction rate.
Referring to FIG. 5, in this embodiment, adjusting apparatus 140 will be identified when being adjusted to position relationship
The position of the multiple Quick Response Code be adjusted according to a unit pixel point.Ensure the covered Quick Response Code 220 to hiding
Lid Quick Response Code 230 is merged as unit of a pixel.
It in this embodiment, can be by adjusting identified the multiple Quick Response Code in the preset template
Position relationship and magnitude relationship, realize it is described generate mixing Quick Response Code the bit error rate be less than error correction rate.Wherein, the bit error rate
Refer to identifying that the error code of generation accounts for the percentage of total identification code when carrying out the mixing Quick Response Code identification.The error correction rate is
The number of codewords of fingering row error correction accounts for the percentage of whole code words.It is illustrated below, such as：The codeword data encoded is needed to be
100, and half relatively therein namely 50 code words carry out error correction, then computational methods are as follows, and error correction needs to be equivalent to code
The symbol that 2 times of word, therefore number of codewords in this case is 50*2=100 code word.Therefore, whole number of codewords are
200, wherein the code word as error correction is 50, so being calculated, the error correction rate relative to whole code words is exactly 25%.Such as
The following table 1 is the error correcting capability table of QR codes, this ratio is equivalent to " Q " rank in QR code level of error correction.
| Error-correction level | It can restore code word ratio |
| L | 7% |
| M | 15% |
| Q | 25% |
| H | 30% |
Table 1
