Title:
INTRA-PREDICTION-BASED IMAGE CODING METHOD AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/194500
Kind Code:
A1
Abstract:
A picture decoding method carried out by a decoding device, according to the present invention, comprises the steps of: detecting intra-prediction modes of a plurality of luma blocks in a luma region corresponding to a current chroma block; generating a first predicted block for the current chroma block on the basis of a first intra-prediction mode, among the intra-prediction modes of the plurality of luma blocks; generating a second predicted block for the current chroma block on the basis of a second intra-prediction mode, among the intra-prediction modes of the plurality of luma blocks; generating a predicted block for the current chroma block on the basis of a weighted sum using the first predicted block and the second predicted block; and generating a reconstructed block on the basis of the predicted block for the current chroma block.
