VIDEO SIGNAL PROCESSING METHOD AND DEVICE

Abstract:

According to the present invention, there is provided a method of decoding an image, the method including: partitioning a current block into multiple sub-blocks; performing intra prediction on a first sub-block among the multiple sub-blocks by using a first sub reference sample line; and performing intra prediction on a second sub-block among the multiple sub-blocks by using a second sub reference sample line. Herein, an intra prediction mode of the first sub-block and an intra prediction mode of the second sub-block are the same.
