4. A non-transitory computer readable medium storing a bitstream,
the bitstream comprising information that causes a decoder to execute a decoding process for decoding, on a block-by-block basis, an image included in the bitstream, the decoding process comprising:
dividing a current block that is a unit of decoding into a plurality of sub-blocks each of which is a unit of prediction;
deriving, for each of the plurality of sub-blocks, one or more prediction information candidates each of which is a candidate for prediction information indicating a reference picture list, a motion vector, and a reference picture index; and
decoding the current block using the one or more prediction information candidates,
wherein the deriving includes:
determining, for each adjacent block that is adjacent to a sub-block among the plurality of sub-blocks, whether the adjacent block is included in the current block or not included in the current block, and determining a block not included in the current block to be a reference block available to the sub-block;
determining a block included in the current block not to be the reference block; and
deriving a prediction information candidate of the sub-block from the predication information of the reference block.
