Research Abstract	Two technologies for the automatic realization of "corresponding color reproduction" between a scene and media under various illumination conditions were studied. First, we succeeded in developing a new robust illumination chromaticity estimation method, which is based on the incomplete image segmentation and the di-chromatic reflection model. This method works especially well for the images of artifacts. Second, we conducted experiments on incomplete chromatic adaptation of human color vision between color images on two displays, whose white points are not the same. The experiments for eight white chromaticity pairs showed interesting results that the obtained incomplete adaptation coefficients are neither constant nor symmetric, and the human color vision adapts to the color temperature that is near the lower one of the two white points.
