This paper describes about the quality or fidility of the decommpressed image. The original image include the random noise, and if we try to decompress the noise, the coding efficiency is not good. If we remove the noise from the original and add noise after decompression, we can improve the coding efficiency keeping the quality. As the higher resolution image include more noise, this cut and add methode is effective for higher resolution image. The relations between the resolution and coded information are shown in graphs and also with formulae.
