Abstract

A non-transitory computer-readable storage medium storing an image processing program causing a computer to execute an image processing on image data to be processed, the image processing program including an obtaining step obtaining the image data, a gradation conversion processing step performing gradation conversion processing on the image data at an intermediate part of gradation according to input/output characteristics having characteristics to which characteristics to reduce a contrast are added, and a correcting step making a correction to enhance a local contrast indicative of contrast at a local part of an image for the image data subjected to the gradation conversion processing by using a gain curve in which a degree of enhancement changes in accordance with luminance information of a pixel to be processed, and thus, bright and dark part gradations are improved while suppressing a change in a hue and color saturation as well as maintaining an apparent contrast.
