| Abstract | According to the present invention, an image encoding/decoding method may include the steps of: generating a matching table including a plurality of candidates; and selecting one candidate from the matching table on the basis of a luma reconstructed sample in a luma block and deriving a prediction value of a chroma sample at the same location as the luma reconstructed sample on the basis of the selected candidate. Therefore, encoding/decoding efficiency can be improved by predicting a chroma block by using a reconstructed luma block.
본 발명에 따른 영상 부호화/복호화 방법은, 복수 후보들을 포함하는, 매칭 테이블을 생성하는 단계; 및 루마 블록 내 루마 복원 샘플을 기초로, 상기 매칭 테이블로부터 하나의 후보를 선택하고, 상기 선택된 후보를 기초로, 상기 루마 복원 샘플과 동일 위치인 크로마 샘플의 예측값을 유도하는 단계를 포함할 수 있다. |
