PROBLEM TO BE SOLVED: To provide an encoding method for motion information with high encoding efficiency.SOLUTION: An image encoding method of the invention performs: a first step of selecting one or more reference motion blocks from encoded pixel blocks having motion information; a second step of selecting, from the reference motion blocks, one or more usable blocks that are pixel blocks having candidates for motion information to be applied to blocks to be encoded, which have motion information different from each other; a third step of selecting one selected block from the usable blocks; a fourth step of generating predicted images of the blocks to be encoded by using motion information of the selected block; a fifth step of encoding prediction errors between the predicted images and an original image; and a sixth step of encoding selection information for specifying the selected block referring to a predetermined code table, according to the number of the usable blocks. |
