ABSTRACT:
The image processing method and device photograph a subject or transparent image to acquire calorimetric values of a subject image, acquire chromaticity information and illuminance information of a light source illuminating the subject and the transparent image, perform on the calorimetric values of the subject image chromatic adaptation correction based on the chromaticity information and the acquired illuminance information and contrast correction based on the illuminance, and correct the corrected calorimetric values to be output by an amount of flare in outputting the subject image, thereby enabling faithful reproduction of appearance. The method and device further perform at least one of contrast conversion and chroma conversion on the calorimetric values of the subject image based on a chromaticity value in a case where a degree of adaptation or an adaptation luminance is set higher than that determined for an illuminating color of the light source before performing the chromatic adaptation correction, thereby enabling faithful reproduction of appearance and preferred color reproduction of appearance.
