Claim One:
1. A two-dimensional code recognition method using a computer comprising: a focused point pixel information detection step of detecting a reference point correspondence position of a recognition target image, calculating a focused point correspondence position on a recognition target image corresponding to a focused point set while being associated with a reference point based on the reference point correspondence position, detecting pixel information of the recognition target image based on the calculated focused point correspondence position, calculating a point placement reserved position on a recognition target image as the focused point correspondence position while using a point placement reserved position belonging to a main layer in a two-dimensional region as the focused point, and detecting the pixel information of the recognition target image based on the calculated point placement reserved position; and a correspondence data calculation step of calculating correspondence data associated with a two-dimensional code based on the detected pixel information, determining a binary data string based on the detected pixel information, and calculating given data uniquely associated with the determined binary data string as the correspondence data, wherein at least one of the steps is executed using a processor.
