Based on the logarithmic and exponential transform, an efficient Log-Exp still image compression system is proposed. The Log-Exp compression is designed for the high quality still image, especially for the PSNR above 36. At similar image quality (Log-Exp PSNR=41.52 and JPEG PSNR=41.23), the Log-Exp compression can get a higher compression ratio than JPEG by a factor of1.84 times for the benchmark image Lena. Besides, the Log-Exp compression is computed in pixel-by-pixel without the block artifacts. In comparison with the JPEG compression result (bpp=0.99. PSNR=26.9), the Log-Exp compression uses less bpp (bpp=0.87) to get higher image quality (PSNR=36.38) for the benchmark image baboon
