Abstract
Color correction matrix determining method and apparatus and image photographing method and apparatus are used in a color processing system that converts input image data into output image data and has two color correction matrixes that are a first matrix and a second matrix, with a white balance correction circuit being sandwiched between the first matrix and the second matrix. The color correction matrix determining method and apparatus input a light source range and determines the first matrix based on this inputted light source range on the occasion of determining the color correction matrix in the color processing system. The image photographing method and apparatus discriminates a photographing light source range and determines the first matrix based on the discriminated photographing light source range.
