A Region-based Dichromatic (RBD) method for estimating illumination colons in an image is proposed. In this method, a property that each highlight on dielectric material has peculiar two reflection components is used. The procedure of this method is as follows; first, high luminance regions are extracted, second, they are divided into similar color regions, third, the regions which involve two reflection components are regarded as highlight regions, last, illumination color is estimated from the cross points of highlight lines in the chromaticity diagram. In conventional illumination color estimation method based on the Dichromatic theory, pixels whose colors are similar to illumination color affect the estimation result. The RBD method solved this serious problem.
