摘要

A prediction signal generator (103) within a video prediction encoding device comprises: a means (122) for estimating a No. 0 motion vector for obtaining a No. 0 prediction signal, selecting a No. 0 prediction motion vector similar to the No. 0 motion vector, and generating No. 0 additional information which comprises a No. 0 prediction motion information index for identifying the prediction motion vector, and a difference motion vector that is determined by the No. 0 motion vector and the No. 0 prediction motion vector; a means (121) for selecting a motion vector for generating a No. 1 prediction signal that is highly correlated with an area to be encoded, generating No. 1 additional information comprising a No. 1 prediction motion information index for identifying the motion vector as a No. 1 prediction motion vector, and setting the No. 1 prediction motion vector as a No. 1 motion vector; and a means (123) for combining the No. 0 and No. 1 prediction signals to generate a prediction signal for the area to be encoded.
