摘要

A moving picture encoding method comprises a picture encoding step of encoding a block to be encoded using a motion vector, a prediction motion vector candidate generating step of generating a plurality of prediction motion vectors, and a motion vector encoding step of encoding the motion vector using one of the plurality of prediction motion vectors generated in the prediction motion vector candidate generating step, wherein, in a case where time prediction motion vectors cannot be acquired from a block corresponding to the block to be encoded that is included in an encoded picture that differs from the picture to be encoded (S12), substitution vectors are included in the prediction motion vector candidate generating step in place of the time prediction motion vectors as one of the plurality of prediction motion vectors (S13,S14).
