Abstract

본 발명은 영상 이미지에 대한 섬네일 이미지를 생성하는 방법에 관한 것으로, 보다 구체적으로 영상 이미지를 구성하는 영상 블록에 대한 예측 블록의 DC 계수를 공간 영역의 영상 블록의 예측 참조 픽셀로부터 직접 계산하고, 계산한 예측 블록의 DC 계수와 영상 블록에 대한 오차 블록의 DC 계수로부터 영상 블록의 DC 계수를 계산하여 영상 이미지의 섬네일 이미지를 생성하는 방법에 관한 것이다. 본 발명에 따른 섬네일 이미지의 생성 방법은 영상 블록에 대한 오차 계수 블록의 DC 계수와 영상 블록에 대한 예측 블록의 DC 계수로 직접 영상 블록의 DC 계수를 계산함으로써, 영상 이미지를 구성하는 공간 영역과 변환 영역 사이에서 영상 블록을 변환하지 않고 H.264 표준의 영상 이미지에 대한 섬네일 이미지를 생성할 수 있으며, 다수의 영상 이미지들이 저장되어 있는 멀티미디어 단말기에서 섬네일 이미지를 통해 특정 영상 이미지를 빠르게 검색할 수 있다.
