A photographing device divides corrected image data into four quadrants by x and y axes with a position corresponding to an optical center being an origin (base point), divides each of the quadrants into a plurality of strip regions so that the x axis direction width has a predetermined number of pixels processed, and performs correction for each of the strip regions on a line by line basis within a corresponding strip region (which will be referred to as a "short line" hereinafter in order to distinguish from one line on an entire image). The order of correction for short lines within each strip region starts from a short line which is closest to the x axis and successively proceeds in a direction away from the x axis.
