Abstract

본 발명은 적응적 보간 필터 계수를 이용한 영상 부호화/복호화 방법 및 장치에 관한 것이다. 본 발명은 현재 프레임의 적응적 보간 필터 계수를 계산하는 계수 계산기; 적응적 보간 필터 계수를 이용하여 참조 프레임을 보간하고 보간된 참조 프레임을 이용하여 현재 프레임을 부호화하는 영상 부호화기; 현재 프레임의 적응적 보간 필터 계수에 따라 계수 삽입 플래그 또는 계수 미삽입 플래그를 필터 플래그로서 생성하고 부호화하는 필터 플래그 부호화기; 필터 플래그가 계수 삽입 플래그인 경우, 현재 프레임의 적응적 보간 필터 계수를 부호화하는 계수 부호화기; 및 부호화된 현재 프레임 및 부호화된 필터 플래그를 포함하되, 부호화된 현재 프레임의 적응적 보간 필터 계수를 추가로 포함하는 비트스트림을 생성하여 출력하는 비트스트림 생성기를 포함하는 것을 특징으로 하는 영상 부호화 장치를 제공한다. 본 발명에 의하면, 적응적으로 보간 필터 계수를 결정하여 영상을 부호화하면서도 적응적으로 결정되는 필터 계수에 대한 정보를 부호화하기 위한 비트량을 줄여 부호화 효율 또는 압축 효율을 향상시킬 수 있다.
