<p><P>PROBLEM TO BE SOLVED: To improve subjective image quality of a decoded image. <P>SOLUTION: The coded image decoding apparatus acquires encoding information of the coded image from a VLD unit 702, an inverse digitizing unit 703, and a reverse DCT unit 704 and the like, decides the type and/or the strength of a filter by a filter deciding unit 101 in response to the information, and filters the decoded image signal by a filtering unit 102 according to the decision. Thus, a difficult operation to recognize the subjective image quality by the decoded image signal is eliminated, and hence suitable filtering can be conducted. The regenerating speed of the image can be estimated from the coding information. The type and/or the strength of the filter in response to the regenerating speed is decided, and hence the filtering can be conducted as well. <P>COPYRIGHT: (C)2003,JPO</p> |
