Abstract.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.

Many papers concentrate on the 3*3 perspective transformation matrix calculation of bird's view system, but few discussed for the whole system implementation. In this paper, a low-cost bird's-eye view system is proposed, which adopts an elaborate software/hardware cooperative system structure. It can be applied to all kinds of vision-based system in vehicles directly as a ready-made module.
