In the JPEG coding, the compression rate can easily be decided as the coding parameter. When we employ the same coding parameter for some pictures, it is difficult to obtain the same picture qualities for human observer. In this paper, we propose a quality oriented JPEG coding method for color still picture. This coding method can automatically provide the user with the optimal coding parameter corresponding to the previously decided picture quality. By executing the proposed method on the personal computer, it has been found that this method is practically useful for quality oriented communication system.
