A coefficient for a formula to calculate coordinate positions for a center position of each cell is calculated with correcting the inclination of the image by adding depth information (step S3). The coordinate positions of the center position of each cell are calculated by applying the calculated coefficient to a calculation of the formula (step S4). A contrast is determined from image data corresponding to the center position of each cell to create binary data of 0/1 for each cell (step S5). A restore operation is performed on the basis of the binary data (step S6). The formula is expressed by a recurrence formula of the center position of each cell. Each coefficient obtained from four coordinate positions of the two-dimensional code is divided by an identical constant to realize integral arithmetic.
