摘要

An image processing method for balancing colors of an image on the basis of the principle of the color constancy. The image processing method for processing an image photographed by a photographing apparatus, has: converting a color data of the image photographed by the photographing apparatus under a different type light source, so as to adapt at least one different type light source color data which is a color data for color chips including a chromatic color, under at least one different type light source which is different from a standard light source, against a standard light source color data which is a color data for the color chips under the standard light source.
