INTRA PREDICTION-BASED IMAGE CODING METHOD USING MPM LIST, AND DEVICE THEREFOR

Title:

INTRA PREDICTION-BASED IMAGE CODING METHOD USING MPM LIST, AND DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2020/076064

Kind Code:

A1

Abstract:

An image decoding method, according to the present document, comprises the steps of: deriving a first intra prediction mode candidate on the basis of a first neighboring block positioned on the left side of a current block; deriving a second intra prediction mode candidate on the basis of a second neighboring block positioned on the top side of the current block; configuring a most probable mode (MPM) list for the current block on the basis of the first intra prediction mode candidate and the second intra prediction mode candidate; deriving an intra prediction mode for the current block on the basis of the MPM list; generating prediction samples by carrying out prediction on the current block on the basis of the intra prediction mode; and generating a restored picture of the current block on the basis of the prediction samples.
