1. An image decoder comprising:
a memory; and
a processor coupled to the memory and configured to:
determine a first partition and a second partition in a current coding block, each partition having a non-rectangular shape, the first partition being overlapped with the second partition;
select, for the first partition, only a first uni-prediction motion vector from among bi-prediction motion vector candidates for the first partition;
decode the first partition using the first uni-prediction motion vector selected for the first partition, wherein, to decode the first partition, the processor is configured to:
generate a first prediction image of the first partition with the first uni-prediction motion vector selected for the first partition; and
generate a second prediction image of the second partition with a second uni-prediction motion vector; and
generate a prediction image of the current coding block based on the first prediction image and the second prediction image.
