Real-Time Color Gamut Mapping Architecture and Implementation for Color-Blind People
A novel color gamut mapping method and architecture is described. The color gamut mapping allows versatile color display devices to generate transformed colors so that certain colors which are confused can be recognized by the color-blind users. And real-time hardware architecture for color gamut mapping is also described. The concept of three-dimensional reduced resolution look-up table is proposed and applied for color gamut mapping. The proposed architecture greatly reduces the required memory size and computational loads compared to the conventional methods and it is suitable for real-time applications. The proposed real-time architecture can easily be implemented in high-speed color display applications especially for color-blind users. The experimental results show that the proposed method is successfully used for color transform, which enables confused colors to be differentiated.
