Robust Adaptive Image Coding for Frame Memory Reduction in LCD Overdrive

Abstract

Summary form only given. In this paper, Robust Adaptive Image Coding (RAIC) is proposed to increase compression performance for Frame Memory Reduction in LCD Overdrive. The RAIC contains two techniques to improve the quality of decompressed images. The first is a Min-Max (of Block) Adaptive Uniform Quantization Coding (MMAUQC) to improve the quality of decompressed block images. The second is a Multiple Adaptive Quantization Coding (MAQC), which is combined of Range-based Bit Distribution Technique (RBBDT) and MMAUQC. This combination gives multiple adaptive ability that improving the image quality while preserving fixed word length compression feature. RAIC shows the flexible ability in bit distribution of RBBDT, which can expand the search capability to other optimize models. Experimental results show that, compared with other coding methods used in the same type of application, RAIC has outperforming features.
