Abstract

본 발명은 후보 예측 움직임 벡터 집합 선택을 이용한 움직임 벡터 부호화/복호화 방법 및 장치와 영상 부호화/복호화 방법 및 장치에 관한 것이다. 본 발명은 현재 블록의 주변 블록의 움직임 정보를 이용하여 복수 개의 후보 예측 움직임 벡터 집합 중에서 하나의 후보 예측 움직임 벡터 집합을 선택하고, 선택되는 후보 예측 움직임 벡터 집합 내의 후보 예측 움직임 벡터 중에서 하나의 후보 예측 움직임 벡터를 예측 움직임 벡터로서 선택하며, 현재 블록의 움직임 벡터인 현재 움직임 벡터와 선택되는 예측 움직임 벡터의 차이인 차분 벡터를 부호화하며, 선택되는 예측 움직임 벡터를 나타내는 예측 움직임 벡터 인덱스를 부호화하는 단계를 포함하는 것을 특징으로 하는 움직임 벡터 부호화 방법을 제공한다. 본 발명에 의하면, 효율적인 후보 예측 움직임 벡터 집합을 선택하여 움직임 벡터를 부호화함에 따라 부호화할 차분 벡터의 크기를 줄이면서도 어떠한 후보 예측 움직임 벡터 집합이 선택되었는지를 나타내기 위한 부가 정보를 부호화하지 않아도 되므로, 움직임 벡터의 압축 효율을 향상시켜 결과적으로 영상의 압축 효율을 향상시킬 수 있다.
