Abstract: When compression encoding processing of an image is performed in units of macroblocks using a pipeline structure, an application of a skip mode or the like according to MPEG4AVC to compression encode an encoding target block requires motion vectors and the like of adjacent blocks of the encoding target block. However, depending on a structure of the pipeline stages, the motion vectors may not be determined. In such cases, the skip mode cannot be applied to compression encode the encoding target block. This problem can be solved by (i) calculating all motion information candidates, of the encoding target block, corresponding to all motion information selectable by a previous block of the encoding target block, and (ii) selecting, as the motion information of the encoding target block in the skip mode, the motion information corresponding to the motion information determined for the previous block.
