Abstract
An image decoding method performed by a decoding apparatus according to the present document includes deriving a CCLM mode as an intra prediction mode of a current block, deriving a specific value for the current chroma block, deriving, based on the width and the height of the current chroma block being greater than or equal to the specific value, top neighboring chroma samples whose number is equal to the specific value of the current chroma block, and left neighboring chroma samples whose number is equal to the specific value, deriving CCLM parameters based on the top neighboring chroma samples, the left neighboring chroma samples, and down-sampled neighboring luma samples, deriving prediction samples for the current chroma block based on the CCLM parameters and the down-sampled luma samples, and generating reconstructed samples for the current chroma block based on the prediction samples, wherein the derived specific value is 2.
