Claim One:
1. An image encoding method for encoding an image, the image encoding method comprising: selecting one motion prediction model from a plurality of motion prediction models for each of blocks in the image, the plurality of motion prediction models including a translational motion model and a non-translational motion model different from the translational motion model; performing motion prediction using the selected motion prediction model to generate a prediction image for each of the blocks; generating a reconstructed image for each of the blocks using the prediction image; determining that filtering is to be performed if the non-translational motion model is selected for at least one of a first block and a second block, the first block being one of the blocks, and the second block being another one of the blocks and adjacent to the first block; and performing the filtering on a boundary between the reconstructed image for the first block and the reconstructed image for the second block if it is determined in the determining that the filtering is to be performed, the filtering being for reducing an image distortion at the boundary.
