Abstract
The present invention provides an image processing method on the basis of an intra prediction mode and an apparatus therefor. Specifically, a method for processing an image on the basis of an intra prediction mode may comprise the steps of: inducing a prediction mode applied to an intra prediction of a current block; determining whether a bi-directional intra prediction using reference samples located at both boundaries of the current block with respect to a prediction direction of the prediction mode is applied to the current block; and generating a prediction sample by using a reference sample neighboring the current block on the basis of the prediction mode, wherein when the bi-directional intra prediction is applied, boundary filtering for the current block is skipped.
