摘要

A video coding device for using motion compensated prediction to code video in block units that partition the respective pictures of the video, wherein a prediction mode decision unit (109) derives motion information from a coding-target block. When the coding-target block is a prescribed size or smaller, a motion compensated prediction unit (108) changes the derived motion information for this prescribed size or smaller coding-target block. The motion compensated prediction unit (108) generates a coding-target block prediction signal in accordance with motion compensated prediction by using the derived motion information when the coding-target block is larger than the prescribed size, and by using the changed motion information when the coding-target block is the prescribed size or smaller.
