Title:
符号化装置及び符号化方法
Document Type and Number:
Japanese Patent JP7176094
Kind Code:
B2
Abstract:
An encoder comprises: a processor; and memory coupled to the processor, in which in operation, the processor: generates a first prediction image having full-pel precision, based on a motion vector of the current block; generates a second prediction image having fraction-pel precision by interpolating a value at a fraction-pel position between full-pel positions included in the first prediction image, using a first interpolation filter or a second interpolation filter differing in a total number of taps from the first interpolation filter; and encodes the current block based on the second prediction image, and in the generating of the second prediction image, the processor switches between using the first interpolation filter and the second interpolation filter depending on whether an affine mode is used for the current block.
