Document Type and Number:
WIPO Patent Application WO/2019/022537
Kind Code:
A1
Abstract:
An intra-prediction mode-based image processing method, and an apparatus therefor are disclosed in the present invention. Specifically, the method for processing an image based on an intra-prediction mode may comprise the steps of: deriving an intra-prediction mode of a current block; deriving a first reference sample from at least one reference sample of a left, an upper, an upper left, a lower left and an upper right reference sample of the current block based on the intra-prediction mode; deriving a second reference sample from at least one reference sample of a right, a lower and a lower right reference sample of the current block based on the intra-prediction mode; dividing the current block into a first sub-region and a second sub-region; generating a prediction sample for the first sub-region using the first reference sample; and generating a prediction sample for the second sub-region using the first reference sample and the second reference sample.
