Title:

IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM STORING BITSTREAM

Document Type and Number:

WIPO Patent Application WO/2020/226359

Kind Code:

A1

Abstract:

Provided are an image encoding/decoding method and device. The image decoding method, according to the present invention, comprises the steps of: determining an intra prediction mode of a current block; and generating a prediction block of the current block by performing prediction on the basis of the intra prediction mode, wherein, when the intra prediction mode of the current block is a matrix-based intra prediction (MIP) mode, the length of a reference sample used for intra prediction can be derived on the basis of the length of the current block.
