<p>A video image encoding method includes an image encoding step of encoding a block to be encoded, the encoding being performed using a motion vector; prediction motion vector candidate generation steps (S11, S12) of generating a plurality of prediction motion vectors; and a motion vector encoding step (S13) of encoding a motion vector using one of the prediction motion vectors. In an instance in which a block corresponding to the block to be encoded included in a picture that has already been encoded has two reference motion vectors, and the reference directions of the two reference motion vectors are the same (S11), in the prediction motion vector candidate generation step (S12), a first prediction vector is generated using the first reference motion vector, and a second prediction vector is generated using the second reference motion vector.</p> |
