Abstract:
Color processing is performed for an image such that more preferable color representation can be obtained under viewing environments having different viewing conditions. Hence, a setting unit inputs a plurality of viewing conditions of the output side of an image. A calculation unit sets a viewing condition used to calculate an ambient light parameter, based on the plurality of viewing conditions, and calculates an ambient light parameter based on the set viewing condition. A conversion unit performs inverse conversion of a color appearance model to color data by using the ambient light parameter.
