In this paper, we developed a high compression ratio image coding (HCRIC) for frame memory reduction in LCD overdrive to reduce motion blur. We have used the characteristic of human visual system (HVS) to separate the luminance data and chrominance data, firstly. And then use different methods to compress them. The image codec can reduce the frame memory to 1/6, and by using a new architecture it can reduce the line buffer to 50% without any image degradation. The simulation results show that it can gain the mean image degradation of 35.27㏈ in peak signal to noise ratio (PSNR). The image codec is implemented by the Verilog HDL and synthesized by the Synopsys design compiler using 0.13㎛ Samsung Library.
