Color image processing method, color image processing device, and recording medium
Abstract:
To provide a color image processing method and device capable of improving the texture of a specific object in a color image taken by a color imaging device by controlling the quantity of a specular component in the specific object. A color image processing device (100) includes 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, a specular component correction unit (130) that corrects the specular component, and a reproduced-color calculation unit (140) that calculates a reproduced color of the object area by using the shade in the body reflection component and the corrected specular component and generates an output image.
