A method for predictively decoding a motion vector used in motion compensated prediction to restore a video sequence consisting of a temporal sequence of a plurality of frame pictures, comprising: a step (S302) of determining a first motion vector predictor candidate (PMV1) that satisfies a predetermined criterion used in determination of motion vector predictor candidates, from motion vectors of partitions (BD, BL2, BL1, BL) belonging to a left-neighboring region located on the left side of a target partition (BT) in a frame picture of a decoding target; a step (S303) of determining a second motion vector predictor candidate (PMV2) satisfying a predetermined criterion used in determination of motion vector predictor candidates, from motion vectors of partitions (BRA, BA2, BA1, BA, BE) belonging to an above-neighboring region located above the target partition (BT); a step (S806) of decoding coded data and restoring motion vector predictor indication information that specifies an optimum motion vector predictor of the target partition (BT); and a step (S807) of selecting the optimum motion vector predictor specified by the motion vector predictor indication information, from motion vector predictor candidates including at least the first motion vector predictor candidate (PMV1) and the second motion vector predictor candidate (PMV2); characterized in that the step (S303) of determining a second motion vector predictor candidate (PMV2) determines a motion vector that satisfies the predetermined criterion used in determination of motion vector predictor candidates as a second motion vector predictor candidate (PMV2), from motion vectors of partitions, by scanning partitions (BRA, BA2, BA1, BA, BE) belonging to the above-neighboring region from a right direction to a left direction, and by decimating the number of partitions to be scanned the partitions scanned from the right direction to the left direction is a reduced set of partitions. a step (S302) of determining a first motion vector predictor candidate (PMV1) that satisfies a predetermined criterion used in determination of motion vector predictor candidates, from motion vectors of partitions (BD, BL2, BL1, BL) belonging to a left-neighboring region located on the left side of a target partition (BT) in a frame picture of a decoding target; a step (S303) of determining a second motion vector predictor candidate (PMV2) satisfying a predetermined criterion used in determination of motion vector predictor candidates, from motion vectors of partitions (BRA, BA2, BA1, BA, BE) belonging to an above-neighboring region located above the target partition (BT); a step (S806) of decoding coded data and restoring motion vector predictor indication information that specifies an optimum motion vector predictor of the target partition (BT); and a step (S807) of selecting the optimum motion vector predictor specified by the motion vector predictor indication information, from motion vector predictor candidates including at least the first motion vector predictor candidate (PMV1) and the second motion vector predictor candidate (PMV2); characterized in that the step (S303) of determining a second motion vector predictor candidate (PMV2) determines a motion vector that satisfies the predetermined criterion used in determination of motion vector predictor candidates as a second motion vector predictor candidate (PMV2), from motion vectors of partitions, by scanning partitions (BRA, BA2, BA1, BA, BE) belonging to the above-neighboring region from a right direction to a left direction, and by decimating the number of partitions to be scanned the partitions scanned from the right direction to the left direction is a reduced set of partitions. <EOS>
