Title:
IMAGE DECODING DEVICE, IMAGE DECODING METHOD, AND IMAGE DECODING PROGRAM
Document Type and Number:
Japanese Patent JP2022046467
Kind Code:
A
Abstract:
To provide an image encoding device, image encoding method, image encoding program, image decoding device, image decoding method, image decoding program, and data structure of encoded data that provides inter-prediction mode with higher efficiency by correcting a motion vector in a merge mode.SOLUTION: An inter-prediction unit of the image encoding device generates a merge candidate list, selects a merge candidate from the merge candidate list as a selected merge candidate, decodes a code string from an encoding stream to derive a correction vector, adds a motion vector of a first prediction of the selected merge candidate without scaling the correction vector, and derives a correction merge candidate by subtracting the correction vector without scaling from the motion vector of a second prediction of the selected merge candidate.SELECTED DRAWING: Figure 3
