摘要

Predictive coding method, predictive coding device and motion vector predictive coding program, and predictive decoding method, predictive decoding device and motion vector predictive decoding program The present invention relates to a predictive coding method motion vectors according to one embodiment including: (a) a step of determining a motion vector of a target partition in a frame image of a coding target; (b) a step of determining a first predictive motion vector candidate from a motion vector or motion vectors of one or more partitions belonging to a left region adjacent to the target partition; (c) a step of determining a second predictive motion vector candidate from a motion vector or motion vectors of one or more partitions belonging to a region above neighboring the target partition; (d) a step of selecting an ideal predictive motion vector to produce predictive motion vector indication information to specify the selected ideal predictive motion vector, the selected ideal predictive motion vector based on the comparison between one or more candidate candidates. predictive motion vector including the first candidate predictive motion vector and the second predictive motion vector, and the target partition motion vector; and (e) a step of encoding predictive motion vector indication information.
