Patent ID: 8855371

Claim:
A color image processing method comprising: detecting, by a processor, an object area which is an area to be subjected to image processing from an input image; calculating, by the processor, color information of the object area and a perfect diffusion component which is a low-frequency component of the object area; reconstructing, by the processor, a surface reflection component based on the color information and the low-frequency component; correcting, by the processor, the reconstructed surface reflection component according to a reference surface reflection component that is the surface reflection component set in advance according to the object area; calculating, by the processor, a reproduced color that is a color obtained by correcting each pixel included in the input image by using the perfect diffusion component and the corrected surface reflection component; and generating, by the processor, an output image based on the reproduced color, wherein a correction value that is information used when the surface reflection component is corrected is input from a user, and when the reconstructed surface reflection component is corrected, the surface reflection component is corrected using the input correction value.
