摘要

A movement vector detection unit (104) detects a movement vector of a block to be encoded with respect to a first reference image. A unit (107) for compositing a plurality of reference images generates a composite reference block that is a result of compositing a first reference block extracted from the first reference image using the movement vector, and a prescribed area of at least one of the other reference images. An entropy encoding unit (118) encodes an estimated difference block, which is a result of subtracting an estimation block from the block to be encoded, using the composite reference block as the estimation block.
