Saturation to white and fading of subjects' faces are prevented when performing density correction on digital images. An average signal value, obtained from a photographic image, is compared against a predetermined reference value, to judge whether correction is to be administered to brighten or darken the photographic image. A corrected image constituted by corrected signal values, which are obtained by correcting the pixel signal values of the photographic image with a predetermined correction amount, is generated only in cases that it is judged that correction to brighten the photographic image is to be administered. At this time, if the brightness represented by signal values of pixels of the photographic image are greater than or equal to a predetermined brightness, the correction amount is gradually reduced as the signal values become brighter.
