ABSTRACT:
The aperture correction system variably adjusts a correction efficient value based upon a sign and an original relative light intensity value or its equivalent. Because the correction is relative light intensity sensitive, the aperture correction is optimized, and the average light intensity is maintained before and after the aperture correction for natural appearance of the image.
