INTRA-PREDICTION MODE-BASED IMAGE PROCESSING METHOD AND APPARATUS THEREFOR

摘要

Disclosed are an intra-prediction mode-based image processing method and an apparatus therefor. Specifically, a method for processing an image on the basis of an intra-prediction mode comprises the steps of: determining an intra-prediction mode for a processing block; selecting reference samples for the processing block; if the intra-prediction mode is a planar mode, then selecting, according to the planar mode type and from among the reference samples, a reference sample to be used in the prediction of the processing block; and generating a prediction sample for the processing block utilizing the selected reference sample.
