A Hybrid Image Coding in Overdriving for Motion Blur Reduction in LCD

Overdriving technique enlarges the desired change of the pixel value,the error in general compression methods is enlarged at the same time. Therefore, we propose a novel Adaptive Quantization Coding (AQC) to reduce the error in compression for overdriving technique reducing motion blur. Considering hardware implementation, we develop a hybrid image coding which uses color transform first, and then uses AQC to compress luminance data as well as Block Truncation Coding (BTC) to compress chrominance data. The simulation results shown that the average PSNR was improved 5.676dB as compared with the result of BTC, and the average SD of error was reduced 50.2% than that in the BTC. The proposed algorithm is implemented with the verilog HDL and synthesized with the synopsys design compiler using 0.13μm Samsung Library.
