Wide color-gamut improvement with skin protection using content-based analysis for display systems

In this paper, we propose an improved color-gamut method for Liquid Crystal Displays (LCD) with Multi-Phosphor White Light Emitting Diodes (MPW LED) and a modified rich color image processing method with skin protection. The human skin tone is typically memorized by color information. In order to increase the color saturation, the traditional rich color method makes skin color unnatural, so a modified rich color method with human skin colors protection is proposed. It has better quality than the traditional one. In mobile display systems, due to the limitation of bandwidth and memory capacity, how to realize the functions of rich color image processing method with skin protection on mobile display platform is an important issue. Moreover, we have implemented our proposed method in the FPGA and displayed the image on the ARM platform.
