    摘要: As a prediction vector is set a prediction vector selected from one of a first prediction vector candidate and a prediction vector candidate in accordance with an encoding cost. The prediction vector candidate is a prediction vector candidate selected from one of a second prediction vector candidate and a third prediction vector candidate in accordance with a predictive accuracy of the third prediction vector candidate. The first prediction vector candidate is a median of motion vectors assigned to respective partitions surrounding a target partition. The second prediction vector candidate is a motion vector assigned to a partition adjacent to a left side of the target partition. The third prediction vector candidate is a motion vector assigned to a collocate partition identical in location to the target partition of a decoded frame.
