ABSTRACT:
Disclosed herein is an information processing device for recognizing a two-dimensional code in which predetermined information is coded by two-dimensionally arranging a plurality of cells according to a predetermined arrangement rule, the information processing device including detecting means and obtaining means. In the information processing device, the detecting means detects the position determining part on a basis of binarized data obtained as a result of binarizing the image of the two-dimensional code on a basis of a first threshold value. The obtaining means detects the arrangement rule of the cells present in the area identified by the position determining part on a basis of binarized data obtained as a result of binarizing the area identified by the position determining part on a basis of a second threshold value different from the first threshold value, and obtains the predetermined information.
