REQUIREMENTS FOR THE DISPOSAL OF VEHICLES, DECODING REQUIREMENTS FOR VEHICLES AND CODING REQUIREMENTS FOR VEHICLES

摘要

A load in processing of searching for a motion vector is reduced. In order to solve the problem described above, a motion vector derivation apparatus (3032, 3036 to 3038) according to one aspect of the present invention that derives a motion vector to be referred to for generating a prediction image to be used for coding or decoding of a video includes a motion vector search unit (30373) configured to search for a motion vector on a prediction unit basis through matching processing. The motion vector search unit (30373) is configured to stop search of the motion vector, depending on whether or not a conditional expression according to a pixel bit-depth is satisfied.
