Abstract:
1. A picture encoding method of encoding a picture on a block-by-block basis, said method comprising: deciding a candidate for a prediction method in which a size of motion compensation and a direction of motion prediction are set for a block to be coded; applying motion estimation to the block, by selecting an optimal prediction method using the decided candidate for the prediction method, calculating a motion vector for the block using the selected optimal prediction method, and generating predictive image of the block using the calculated motion vector; and encoding an image of the block using the generated predictive image, wherein said deciding of the candidate for the prediction method includes: wherein the size of motion compensation is a size of a part formed by dividing the block into a plurality of parts, and wherein in said applying motion estimation, motion compensation is performed for each of the plurality of parts included in the block to calculate a motion vector for each of the plurality of parts.
