Abstract
A measurement target is captured using two types of illumination patterns set such that only color features of specular objects change, the two images that are obtained are compared, and objects are identified as being specular objects or diffuse objects depending on whether the color features change markedly. At this time, the emission intensity distribution of each illumination pattern is devised such that specular lobe components that are included in reflected light are canceled out.
