Abstract

In this paper, we propose a motion picture processor for CSTN-LCD without gamut problem. The proposed method employed CDF(Cumulative Density Function) in order to perform a mutual independent in image gradation and color balance. In addition, the proposed method has solved a gamut problem used by conversion of RGB system and CMY system. Also, we apply the BFI (Black Field Insertion) to the design to compensate for response time of a LC (Liquid Crystal). The proposed hardware architecture has been implemented and verified using a FPGA on prototype board. Visual test and standard deviation of histogram were introduced to evaluate the result of the proposed method and the original ones.
