<p><P>PROBLEM TO BE SOLVED: To prevent an image step after correction from being visually seen by randomly selecting an aberration correction coefficient from a certain range. <P>SOLUTION: This device for correcting aberration is equipped with: a filter processing part 300 for applying predetermined filter processing based on a filter coefficient to respective R and B channels out of RGB video pixel data; and a filter coefficient setting part 200 for temporally randomly selecting and outputting, as a filter coefficient, one of correction filter coefficients X, Y, Z for correcting phase shifting among the respective R, G and B video pixel data caused by color aberration of a lens in a correction area A corresponding to a distance to an objective pixel and two correction areas B, C adjacent to the correction area A by using, as inputs, a distance to an object pixel becoming an object of the filter processing or relative coordinates, the diaphragm, focal length and focus position of an optical lens by concentrically dividing a video signal into a plurality of correction areas from the position thereof corresponding to the optical center of the optical lens. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
