Abstract

A video decoding method according to the present document is characterized by comprising: obtaining Most Probable Mode (MPM) index information and reference line index information from a bitstream; compiling an MPM list including candidate intra prediction modes for the intra prediction of a current block; deriving an intra prediction mode for the current block from among the candidate intra prediction modes included in the MPM list on the basis of the MPM index information; generating prediction samples for the current block on the basis of the intra prediction mode; and generating reconstructed samples for the current block on the basis of the prediction samples, wherein the step for compiling the MPM list involves deriving a DC mode as one of the candidate intra prediction modes, and including the DC mode in the MPM list, the DC mode being derived on the basis of the value of reference line index information indicating a reference line used for the intra prediction of the current block not being zero.

Description

technical field [0001] This document relates to image coding techniques, and more particularly, to an image coding method using Most Probable Mode (MPM) list-based intra prediction and an apparatus thereof. Background technique [0002] Demands for high-resolution and high-quality images and videos such as ultra-high-definition (HUD) images and 4K or 8K or larger videos are increasing recently in various fields. As image and video data become high resolution and high quality, the relative amount of transmitted information or the number of bits increases compared with existing image and video data. Therefore, if image data is transmitted using a medium such as an existing wired or wireless broadband line or image and video data is stored using an existing storage medium, transmission costs and storage costs increase. [0003] Furthermore, there has recently been increasing interest and demand for immersive media such as virtual reality (VR), artificial reality (AR) content, ...
