Abstract
A WB gain calculation unit 24 determines a light source of a Surface A on the basis of color distribution of the Surface A and a black body locus AD, determines a light source of a Surface B on the basis of color distribution of the Surface B and a black body locus BD and determines a light source of a Surface AB on the basis of color distribution of the Surface AB and a block body locus ABD and calculates the white balance gains on the basis of the determined light sources.
