Abstract

This paper proposes a low complexity near-lossless image compression method and its ASIC design for the wireless endoscopy system. Assuring high image quality (PSNR larger than 46.37dB and every pixel error is less than 2), the proposed method can provide lower compression rate (3.5bits/pixel) and lower complexity than any conventional interpolation-first methods and other existing similar compression-first methods. In addition, the ASIC design of this compression method is also given out. The hardware design has been verified on FPGAs and implemented in 0.18mum CMOS process
