Title:
CODING DEVICE, DECODING DEVICE, CODING METHOD, AND DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/141591
Kind Code:
A1
Abstract:
A coding device (100) that codes coding target blocks of an image is provided with a processor (a1) and memory (a2) that is connected to the processor (a1). The processor (a1) generates, for a motion, a first predicted image having an integer pixel unit on the basis of a motion vector, and uses an interpolation filter to interpolate the values of the minimum pixel positions between a plurality of integer pixels included in the first predicted image, thereby generating a second predicted image, and, on the basis of the second predicted image, codes coding target blocks. Usage of the interpolation filter involves switching between a first interpolation filter and a second interpolation filter in which the number of taps differs from the first interpolation filter.
