Title:
IMAGE ENCODING DEVICE, IMAGE ENCODING METHOD, IMAGE ENCODING PROGRAM, IMAGE DECODING DEVICE, IMAGE DECODING METHOD, AND IMAGE DECODING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/137539
Kind Code:
A1
Abstract:
Provided is a technology for improving encoding efficiency by performing block division suitable for encoding and decoding an image. The present invention is provided with: an encoded information storage unit that adds inter-prediction information used for inter-prediction to a history predictive motion vector candidate list; a history predictive motion vector candidate derivation unit that derives history predictive motion vector candidates from the history predictive motion vector candidate list; and a history merge candidate derivation unit that derives history merge candidates from the history predictive motion vector candidate list. The history predictive motion vector candidate derivation unit and the history merge candidate derivation unit refer to the candidates included in the history predictive motion vector candidate list in orders different from each other, and designate each of the candidates as a history predictive motion vector candidate or a history merge candidate.
