摘要

The moving picture encoding apparatus divides a picture end block including one of a horizontal end and a vertical end of a picture to be coded among a plurality of blocks obtained by dividing a picture to be coded according to a four-minute tree structure, Alternatively, a split pattern determination unit for dividing the picture end block into a plurality of sub-blocks and dividing the picture end block into two or more sub-blocks in a direction orthogonal to the end of the encoding target picture included in the picture-end block, and for each sub-block another encoded picture or encoding A prediction block generating unit that generates a prediction block by referring to a region where a target picture has been coded, and a prediction error between each subblock and a corresponding pixel of a prediction block corresponding to the subblock, and encoding the prediction error The division information indicating whether a division is divided into 4 or 2 for a picture and a block of picture stages is encoded. It has added to added to the image data portion.
