Classification: CPC G  H | IPC G  H

Claim 11:
12. A method for reading the two-dimensional symbol according to claim 1 comprising:
an imaging step to capture an image of the two-dimensional symbol;
a first decoding step to determine the coloration pattern of the first modules in the first recording area on the basis of the image captured in the imaging step and decode the first data; and
a second decoding step to determine the coloration pattern of the second modules in the second recording area on the basis of the image captured in the imaging step and decode the second data, wherein
in the first decoding step, the center position of the first modules in the image is specified on the basis of the finder pattern and the timing pattern included in the image captured in the imaging step, and
in the second decoding step, the intermediate point between the adjacent first modules in the image is specified on the basis of the center position of the first modules specified in the first decoding step, and a color of the second module is identified on the basis of a color near the intermediate point.
