Title:
CODING DEVICE, DECODING DEVICE, CODING METHOD, AND DECODING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/193775
Kind Code:
A1
Abstract:
A coding device (100) is provided with a circuit and a memory connected to the circuit. The circuit in operation: performs a first process in which a first filter is applied to a first image to generate a second image, the second image is held as a reference image, and the second image is displayed, and a second process in which a second filter is applied to the first image to generate a second image, the second image is not saved as a reference image, the first image is held as a reference image, and the second image is displayed; writes a coefficient of each of one or more filter candidates that are candidates for the second filter to a bit stream in a state of being included in a first storage location; and writes a parameter designating, for each image, one of the one or more filter candidates as the second filter to the bit stream in a state of being included in a second storage location different from the first storage location.
