Abstract

다중 예측 필터를 이용하는 경쟁기반 인트라 예측 부호화/복호화 장치 및 방법이 개시된다. 본 발명의 실시예에 따른 인트라 예측 부호화 장치는, 부호화하고자 하는 현재블록의 각각의 인트라 예측 방향 또는 모드 별로 현재블록 주변의 화소들을 필터링하는 복수 개의 외삽 예측 필터 후보를 구비하며, 복수 개의 외삽 예측 필터 후보 중 부호화 비용이 가장 적은 필터를 선택하는 최적필터 선택부; 최적필터 선택부에 의해 선택된 필터를 통해 현재블록의 외삽 예측 값을 생성하며, 생성된 현재블록의 외삽 예측 값과 현재블록의 화소 값 사이의 차이를 계산하여 잔여 신호를 생성하는 잔여신호 생성부; 잔여신호 생성부에 의해 생성된 잔여 신호를 변환 및 양자화하는 변환 및 양자화부; 및 변환 및 양자화된 잔여 신호를 엔트로피 부호화하는 엔트로피 부호부를 포함하는 것을 특징으로 한다.
