摘要： A picture encoding method of the present invention is a picture encoding method of predictively encoding an input picture with reference to pictures stored in a picture buffer, decoding the encoded input picture, judging whether or not the decoded picture is a picture for reference and whether or not the decoded picture is a picture for output which needs to be stored until its display time, and storing, in the picture buffer, the picture for reference and the picture for output based on the determination result.

摘要： When a block (MB22) of which motion vector is referred to in the direct mode contains a plurality of motion vectors, 2 motion vectors MV23 and MV24, which are used for inter picture prediction of a current picture (P23) to be coded, are determined by scaling a value obtained from averaging the plurality of motion vectors or selecting one of the plurality of the motion vectors.
