Abstract:
A method for intra prediction comprises determining a first MPM candidate corresponding to a left-side candidate block on the basis of a position of the left-side candidate block adjacent to a left side of a current block; determining a second MPM candidate corresponding to an upper-end candidate block on the basis of a position of the upper-end candidate block adjacent to an upper end of the current block; generating an MPM candidate list including a plurality of MPM candidates, on the basis of the first MPM candidate and the second MPM candidate; and determining one MPM candidate of the plurality of the MPM candidates that constitute the MPM candidate list as an intra prediction mode of the current block, and performing intra prediction for the current block on the basis of the determined intra prediction mode to generate a prediction block corresponding to the current block.

Claim (Index 2):
An image decoding method by a decoding apparatus, the method comprising:\n deriving a first candidate intra prediction mode based on a left neighboring block of a current block, wherein when the left neighboring block is located outside of a current picture, the first candidate intra prediction mode is set equal to intra DC mode, wherein when the left neighboring block is not located in a current slice in which the current block is located, the first candidate intra prediction mode is set equal to the intra DC mode, wherein when the left neighboring block is not an intra coded block, the first candidate intra prediction mode is set equal to the intra DC mode; deriving a second candidate intra prediction mode based on an upper neighboring block of the current block, wherein when the upper neighboring block is located outside of the current picture, the second candidate intra prediction mode is set equal to the intra DC mode, wherein when the upper neighboring block is not located in the current slice, the second candidate intra prediction mode is set equal to the intra DC mode, wherein when the upper neighboring block is not located in a current largest coding unit (LCU) in which the current block is located, the second candidate intra prediction mode is set equal to the intra DC mode, wherein when the upper neighboring block is not an intra coded block, the second candidate intra prediction mode is set equal to the intra DC mode; determining intra prediction mode for the current block based on the first candidate intra prediction mode and the second candidate intra prediction mode; and generating prediction samples on the current block based on the determined intra prediction mode.
