Embodiment 1
[0102] Please refer to figure 2 , Embodiment 1 of the present invention is:
[0103] The invention provides a decoding method of a one-dimensional code CMOS camera engine, comprising the following steps:
[0104] S1: controlling the CMOS camera engine to take a picture, the picture includes a one-dimensional code and a red cross;
[0105] S2: Calculate the position of the red cross in the picture, and obtain the offset of the red cross relative to the center of the picture according to the calculation result;
[0106] S3: According to the offset, adjust the priority decoding area of the picture by the CPU in the next decoding.
[0107] The S3 is specifically:
[0108] The CMOS camera engine includes a preset memory;
[0109] storing the offset in the memory;
[0110] In the next decoding, after the CPU reads the offset in the memory, it adjusts the priority decoding area of the picture according to the read result.
