Abstract
An encoder that encodes a current block to be encoded in an image is provided. The encoder includes: processor; and memory coupled to the processor, in which, in operation, the processor: generates a first prediction image based on a motion vector, the first prediction image being an image with full-pel precision; generates a second prediction image using an interpolation filter by interpolating a value at a fractional-pel position between full-pel positions included in the first prediction image; and encodes the current block based on the second prediction image, and in the using of the interpolation filter, the interpolation filter is switched between a first interpolation filter and a second interpolation filter differing in a total number of taps from the first interpolation filter.
