摘要：
An intra prediction method performed by a decoding device, according to the present disclosure, comprises the steps of: deriving an intra prediction mode for a current block; deriving neighboring samples of the current block; deriving reference samples for a target sample of the current block among the neighboring samples on the basis of the intra prediction mode; deriving weighted values of the reference samples for the target sample; and deriving a prediction sample of the target sample on the basis of the reference samples and the weighted values.
