Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/139040
Kind Code:
A1
Abstract:
The image encoding/decoding method and device according to the present invention can construct a merge candidate list of a current block, derive motion information of the current block on the basis of the merge candidate list and a merge index of the current block, derive a motion vector difference of the current block, correct a motion vector of the current block by means of the motion vector difference, and carry out motion compensation on the current block by means of the corrected motion vector.
