Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An encoder comprising:
circuitry; and
a memory coupled to the circuitry;
wherein the circuitry, in operation, performs a partition process including:
obtaining a current block from a coding tree unit (CTU);
selecting, from a first set of motion vector candidates, a first motion vector for a first partition in the current block;
calculating first values of a set of pixels between the first partition and a second partition in the current block, using the first motion vector for the first partition;
selecting, from a second set of motion vector candidates, a second motion vector for the second partition;
calculating second values of the set of pixels, using the second motion vector for the second partition; and
calculating third values of the set of pixels by weighting the first values and the second values, and
when a ratio of a width to a height of the current block is larger than 4 or a ratio of the height to the width of the current block is larger than 4, the circuitry disables the partition process.
