<P>PROBLEM TO BE SOLVED: To perform correction processing so that the brightness of a photographed image becomes an almost uniform distribution as a whole by means of a simple computing method. <P>SOLUTION: An image processor comprises an image area setting unit 22 for setting each pixel constituting a photographed photograph image to correction target pixels in turn, and for setting an image area including the correction target pixels and consisting of a plurality of pixels existing near by the correction target pixels; a specified value calculation processing unit 23 calculating a specified value based on the brightness information of the pixels included in the image area for each set image area; and a brightness adjustment processing unit 24 for calculating a corrective value by dividing a target value of the brightness of an entire of the photographed image by the specified value and for performing correction processing of the brightness by multiplying the corrective value to the brightness information of the correction target pixels. <P>COPYRIGHT: (C)2008,JPO&INPIT |
