<p>An object area detection means detects an object area which is an area to be subjected to image processing from an input image. A reflection component reconstruction means calculates color information of the object area and a perfect diffusion component, which is a low-frequency component of the object area, and reconstructs a surface reflection component based on the color information and the low-frequency component. An albedo calculation means calculates an albedo, which is color information obtained by removing shading information, which is information that represents luminance of the perfect diffusion component, from the perfect diffusion component. An albedo correction processing means reconstructs a surface reflectance of the object area based on the albedo and the color information in the object area, and then calculates the corrected albedo, which is color information obtained by correcting the albedo based on the surface reflectance.</p> |
