摘要 |
A moving picture encoding apparatus for dividing a frame image as a coding target in a moving picture signal into plural target regions, detecting motion vectors for the respective target regions, and thereby performing coding based on motion compensation. The moving picture encoding apparatus comprises motion vector prediction means for performing a correction of scaling the motion vector of an adjacent region adjacent to the target region on the basis of the target reference frame image. The motion vector predicting means also performing a determination of an optimum predicted motion vector based on the motion vector of the adjacent region adjacent to the target region and thereby predicting the optimum predicted motion vector after the correction.
