Abstract:
An image decoding method includes a constraint information decoding step of decoding constraint information indicating prohibition of reference from a target tile, which is one of a plurality of tiles obtained by partitioning a picture, to another tile, and a list generation step of generating a prediction motion vector list including a plurality of prediction motion vector candidates and a plurality of prediction motion vector indices each associated with a corresponding one of the plurality of prediction motion vector candidates. In the list generating step, a prediction motion vector list not including a temporal motion vector of a block on a lower right side of the target block is generated.

Claim (Index 1):
An image decoding method comprising:\n decoding, from a bitstream, constraint tile information that indicates a prohibition of reference from a current tile, which is one of a plurality of tiles obtained by partitioning a picture, to another tile; generating a prediction motion vector list that includes a plurality of prediction motion vector candidates and a plurality of prediction motion vector indices respectively corresponding to the plurality of prediction motion vector candidates; decoding, from the bitstream, a prediction motion vector index for a current block included in the current tile and decoding the current block by using a prediction motion vector candidate specified by the decoded prediction motion vector index in the prediction motion vector list, and wherein in the generating of the prediction motion vector list, when (i) the constraint tile information is decoded and (ii) the current block is located at an end of the current tile, the prediction motion vector list not including any temporal motion vectors, each of which refers to another picture which is different from a current picture in which the current block is included, is generated, wherein the constraint tile information is decoded from a sequence header of the bitstream.
