Classification: CPC H | IPC H

Claim 3:
4. An encoder which encodes a video into a bitstream using a predicted image, the encoder comprising:
circuitry; and
memory,
wherein, using the memory, the circuitry:
derives a maximum number based on a partition shape of a first partition in the video, the maximum number being a first number when the partition shape is a square or a rectangle, and the maximum number being a second number different from the first number when the partition shape is a non-square and a non-rectangle;
generates a motion vector candidate list including a plurality of candidates equal to the derived maximum number, the plurality of candidates being for a first motion vector for the first partition;
selects the first motion vector from the plurality of candidates included in the motion vector candidate list;
encodes an index indicating the first motion vector among the plurality of candidates in the motion vector candidate list into the bitstream based on the maximum number; and
generates the predicted image for the first partition using the first motion vector.
