Projector Camera System Presenting Color Information for the Color Vision Deficient

Abstract

There are people who cannot distinguish between specific colors easily. This paper presents an improvement to a system for the color vision deficient. The system consists of a camera that acquires an image of an object and a projector that projects light on that object. One of the features of the system is that it handles real-life objects. When objects have colors that cannot be distinguished, the system converts the color to a distinguishable one using the projector. The improvement in the proposed system is that it produces images with patterns and blinking light to handle conventional color conversion operations that cannot produce distinguishable color images because of excessive multiplicity of color combinations. We verify through experiments the effectiveness of the proposed color projection system with its patterns and blinking light.
