Title:
IMAGE ENCODING/DECODING METHOD AND APPARATUS, AND RECORDING MEDIUM HAVING BITSTREAM STORED THEREIN
Document Type and Number:
WIPO Patent Application WO/2023/234579
Kind Code:
A1
Abstract:
The present invention provides an image decoding method comprising the steps of: determining a chrominance intra prediction mode candidate group of a current chrominance block from a reference block of the current chrominance block; rearranging an intra prediction mode candidate of the chrominance intra prediction mode candidate group of the current chrominance block according to the priority of the intra prediction mode candidate; acquiring, from the chrominance intra prediction mode candidate group, chrominance intra prediction mode information indicating an intra prediction mode of the current chrominance block; and determining the intra prediction mode of the current chrominance block on the basis of the chrominance intra prediction mode information.
