To provide a color image processing method and device to realize desired color reproduction of the object area of a specific object in a color image taken by a color imaging device and thereby to improve the texture. A color image processing device (100) comprises an image information acquisition unit (110) that detects an object area based on an input image, and obtains color information and 3D information of the object area, a reflection information restoration unit (120) that restores a specular component and a body reflection component containing shade of the object area based on the color information and the 3D information, an albedo calculation unit (130) that calculates an albedo by removing the specular component and the shade in the body reflection component from the color information, an albedo correction processing unit (140) that restores a surface reflectance by using the color information and the albedo, and calculates a corrected albedo by correcting the albedo using the surface reflectance, and a reproduced-color calculation unit (150) that calculates a reproduced color of the object area by adding the shade in the body reflection component and specular component to the corrected albedo, and thereby generating an output image. |
