A high encoding efficiency is to be realized. A block selection processing unit 33 selects a block from adjacent motion compensation blocks, in accordance with the block size of the motion compensation block being encoded and the block sizes of the encoded adjacent motion compensation blocks adjacent to this motion compensation block. A predicted motion vector information generation unit 34 generates predicted motion vector information about the motion compensation block being encoded, by using the motion vector information about the selected block. A motion prediction/compensation unit 32 performs an inter prediction by using the predicted motion vector information generated at the predicted motion vector information generation unit 34, and generates predicted image data. |
