摘要

The step of obtaining one or more predicted motion vector candidates comprises: a first candidate generating step of generating a predicted motion vector candidate based on a plurality of motion vectors of a plurality of first adjacent blocks adjacent to a first direction of a processing target block And, a second candidate generation step of generating a predicted motion vector candidate based on a plurality of motion vectors of a plurality of second adjacent blocks adjacent to a second direction of the processing target block, and a second candidate generation step (S500) Is, determining whether the inter-predicted block is included in the plurality of first adjacent blocks (S520), and when it is determined that the inter-predicted block is not included in the plurality of first adjacent blocks, the plurality of second adjacent blocks A motion vector that can be scaled is searched for from a plurality of motion vectors of an adjacent block, and when a motion vector that can be scaled is searched, a scaling process is performed on the searched motion vector (S530).
