Abstract
An intra prediction method according to the present invention comprises the steps of: determining an intra prediction mode for a current block; determining whether to apply a coefficient induced intra prediction (CIIP) to the current block; deriving neighboring reference samples for the current block on the basis of whether the CIIP is applied; and generating prediction samples for the current block on the basis of the intra prediction mode and the neighboring samples. The present invention can generate modified or improved neighboring reference samples and thereby can improve the performance of intra prediction.
