Refer to Fig. 5, in this specific embodiment, adjusting apparatus 140 is to position relationship
When being adjusted, by the position of identified the plurality of Quick Response Code according to a unit pixel
Point is adjusted.Guarantee that described covered Quick Response Code 220 is to hiding Quick Response Code 230 with one
Pixel is that unit merges.
In this specific embodiment, can exist by adjusting identified the plurality of Quick Response Code
Position relationship in described default template and magnitude relationship, it is achieved described generation mixing two dimension
The bit error rate of code is less than error correction rate.Wherein, the described bit error rate refers to carrying out described mixing two
During dimension code identification, identify that the error code produced accounts for the percentage ratio of total identification code.Described error correction rate is
The number of codewords of fingering row error correction accounts for the percentage ratio of whole code word.Illustrated below, such as:
The codeword data needing coding is 100, and half the most therein namely 50 code words
Carry out error correction, then computational methods are as follows, and error correction needs to be equivalent to the symbol of code word 2 times, because of
This number of codewords in this case is 50*2=100 code word.Therefore, whole code words
Quantity is 200, and the code word being wherein used as error correction is 50, so calculating, relatively
Error correction rate in whole code words is exactly 25%.Such as the error correcting capability table that table 1 below is QR code,
This ratio is equivalent to " Q " rank in QR code level of error correction.
| Error-correction level | Code word ratio can be recovered |
| L | 7% |
| M | 15% |
| Q | 25% |
| H | 30% |
