Paper Abstract

A color image of digital camera is obtained by interpolated CFA (Color Filter Array) data from single sensor digital camera. Using JPEG compression method to interpolated data, the maximal compression ratio is less than 90:1. In this paper, an improved compression method is discussed which applied JPEG compression to raw data after two luminance components had been processed further. Results show that CPSNR of improved method is the highest among conventional method and existing methods while the compression ratio is over 90:1. And another attractive result is the image quality is better when the compression ratio up to 120:1, and the conventional JPEG compression method is helpless at such compression ratio. The further work will be concentrate on its application with hardware support.
