Projector Camera System Presenting Color Information for Color Vision Deficiency

There are individual differences in color vision. It is difficult for people with defective cones in the retina to recognize the difference of specific colors. We propose a system using a camera and a projecctor to present color information for color vision deficiency. When there are indistinguishable colors in real objects, the system converts the color to a distinguishable color for projection. The system also produces an image with texture and blinking light when multiple color combinations of indistinguishable colors exist. On projecting the image onto the object, the system equalizes an observed color with a target color by color feedback. Effectiveness of the proposed method is verified through experiments.
