BRIGHTNESS CORRECTION PROGRAM, BRIGHTNESS CORRECTION METHOD, AND BRIGHTNESS CORRECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent deterioration in image quality associated with brightness conversion in a dark image having much noise and a gradation image.

SOLUTION: An image brightness-determining section 141 determines whether a correction target image is a dark image or not, and if so, a noise detecting section 142 detects an image having many noises and turns ON a correction weakening flag. If it is not a dark image, a gradation detecting section 143 detects a gradation image and turns ON the correction weakening flag. A correction executing section 144 executes brightness correction on the basis of the correction weakening flag.
