1. An image decoder comprising:
circuitry; and
a memory coupled to the circuitry;
wherein the circuitry, in operation,
determines whether inter prediction is to be applied to a current block,
in response to a determination that the inter prediction is to be applied to the current block, performs a partition prediction process including:
predicting first values of a set of pixels between a first partition having a non-rectangular shape and a second partition in the current block, using a first motion vector for the first partition;
predicting second values of the set of pixels, using a second motion vector for the second partition;
weighting the first values and the second values; and
generating a prediction image for the current block using the weighted first values and the weighted second values, and
in response to a determination that the inter prediction is not to be applied to the current block, decodes the current block without using the partition prediction process.
