Abstract
An image decoding method according to the disclosure comprises the steps of: determining whether a cross-component linear model (CCLM) mode is applied to a chroma block; acquiring a filtered neighboring luma sample with respect to a neighboring chroma sample adjacent to the chroma block, when it is determined that the CCLM mode is applied to the chroma block; deriving a CCLM parameter by using the neighboring chroma sample and the filtered neighboring luma sample; and generating a prediction block for the chroma block by using the CCLM parameter.
