<P>PROBLEM TO BE SOLVED: To provide an image decoding apparatus and method with a simple configuration capable of reproducing image data coded by a prescribed coding system at a high speed, the prescribed coding system adaptively carrying out coding of an image with a field or frame structure. <P>SOLUTION: In the case of a high speed reproduction mode, decoding processing is applied only to an in-frame coded image coded by a coding system of a frame structure, or coded image data of one field in the in-frame coded image and coded image data of an in-field coded image coded by a field structure coded system. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
