Title:
ENCODING DEVICE, DECODING DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/040036
Kind Code:
A1
Abstract:
This encoding device for encoding each of blocks obtained by dividing an image, is provided with: a weighted bi-prediction unit 181a that performs a weighted mean process with respect to a plurality of reference images by using a weight coefficient selected from a weight coefficient set comprising a plurality of weight coefficients, and that generates a prediction block of a to-be encoded block; and a filter control unit 161 that controls a deblocking filter on the basis of the weighted coefficient employed by the weighted bi-prediction unit 181a for each of two adjacent blocks.
