PROBLEM TO BE SOLVED: To provide a two-dimensional code which correctly reads information even through there is distortion and its reading method. SOLUTION: The position of a data cell is decided in each rectangular area R1 to R9 based on the center position of a cell, cell shape and cell array of positioning symbols 54A to 54C and auxiliary symbols 60A to 60F which are arranged in the areas R1 to R9 that are provided in a two-dimensional code 52. Because of this, even though distortion exists in a read image of the code 52, since distortion in each area R1 to R9 appears in the center position of the cell, cell shape and cell array of the arranged symbols 54A to 54C or 60A to 60F, the distortion of the image is reflected on positioning of a data cell, the center position of the data cell can precisely be decided, and a code that is represented by the code 52 can precisely be read. |
