Abstract
Color perception varies from individual to individual. It is difficult for a person with defective cones in the retina to recognize the difference between specific colors. In this case, he or she may face difficulties in daily life. This paper proposes a method for presenting color information by using a projector camera system. The system automatically detects if there are color combinations of difficult discrimination in the scene. The system, it projects border lines or color names on real object surfaces which have those specific colors so that color vision defectives can discriminate the colors.
