摘要

The object of the present invention is to represent a prediction image signal with a small overhead, to provide motion compensation pixel precision different. Moving image encoding apparatus according to the present invention (20), the motion vector detecting means for detecting a motion vector in a predetermined area to be encoded within the frame image (32), a predetermined region that is encoded within a frame image motion is the motion vector prediction unit that uses the motion vectors to predict the motion vector of the predetermined area to be encoded and (33c), is detected by (32) motion vector detection means, the predicted prediction means by (33c) motion vector determination means for determining whether the motion vectors of predetermined is set according to the vector and (33d), detected by (32) motion vector detection means, and a predetermined case of the motion vector of the given In case it is not the motion vectors, and includes a (33e) switching means for switching the calculation method of the motion compensation values ​​of the predetermined area to be encoded.
