Document Type and Number:
WIPO Patent Application WO/2019/194441
Kind Code:
A1
Abstract:
An image decoding method performed by a decoding device according to the present invention comprises the steps of: constructing an MPM list of a current block on the basis of neighboring blocks of the current block; deriving an intra prediction mode for the current block on the basis of the MPM list; and generating a prediction sample for the current block on the basis of the intra prediction mode, wherein the neighboring blocks include a left neighboring block and an upper neighboring block of the current block, and if the size of the current block is WxH and the x component of an upper left sample position of the current block is 0 and the y component thereof is 0, the left neighboring block includes a sample of coordinates (-1, H-1) and the upper neighboring block includes a sample of coordinates (W-1, -1).
