摘要

This moving picture encoding method includes: a first prediction motion vector calculation step (S111a) in which each first prediction motion vector candidate is calculated from at least one adjoining block; a second prediction motion vector calculation step (S114b, S114c) in which second prediction motion vector candidates having a zero-value motion vector, or third prediction motion vector candidates having a disparity vector with respect to a reference picture which belongs to a different view from that of a picture to be encoded, are calculated; a prediction motion vector determination step (S103) in which prediction motion vectors to be used for encoding motion vectors of a block to be encoded are determined from among the first prediction motion vector candidates and the second prediction motion vector candidates or from among the first prediction motion vector candidates and the third prediction motion vector candidates; and an index encoding step (S104) in which indices for identifying the prediction motion vectors are attached to a bitstream.
