VIDEO ENCODING DEVICE, VIDEO DECODING DEVICE, AND DATA STRUCTURE

摘要

On the basis of coding cost, a prediction vector candidate to be used as a prediction vector is selected from a first prediction vector candidate which is the median of the motion vectors allocated to the partitions around a partition to be encoded; and another prediction candidate which is selected from a second prediction vector candidate, which is the motion vector allocated to the contiguous partition on the left side of the partition to be encoded, and a third prediction vector candidate, which is the motion vector allocated to the collocated partition which occupies the same position in the decoded frame as the partition to be encoded, on the basis of the prediction accuracy of the third prediction vector candidate.
