Abstract

본 발명에 따른 가상 뷰 이미지 합성 방법은 제 1시점의 레퍼런스 픽쳐와 제 2시점의 레퍼런스 픽쳐를 와핑함으로써 제 1시점의 중간 픽쳐와 제 2시점의 중간 픽쳐를 생성하고, 상기 제 1시점의 중간 픽쳐에 홀이 존재하는지를 판별하며, 상기 제 1시점의 중간 픽쳐에 홀이 존재하는 경우, 상기 홀의 위치에 근거하여 상기 제 2시점의 중간 픽쳐의 픽셀값을 획득하고, 상기 제 2시점의 중간 픽쳐의 픽셀값을 상기 홀에 할당하되, 상기 홀은 상기 제 1시점의 중간 픽쳐에 픽셀값이 할당되지 않은 영역인 것을 특징으로 한다. 레퍼런스 픽쳐를 이용하여 가상 픽쳐를 합성함으로써 가상 시점의 픽쳐를 코딩함에 따른 정보량을 줄일 수 있어서 영상 신호 처리를 효율적으로 할 수 있다.
