Abstract
Description
Claims (1)
- M×N의 크기를 갖는 영상의 확장시에 발생되는 블럭킹 현상을 방지하는 방법에 있어서, 상기 영상의 각 픽셀에 대한 동일한 픽셀값을 갖는 픽셀들을 인접한 다른 픽셀들 사이에 삽입하여 설정된 소정 배율로 영상을 확장하는 제1단계; 상기 제1단계에서 확장된 영상의 각 확장블럭간의 인접한 경계픽셀들에 대한 2×2블럭 내의 픽셀들의 평균값을 연산하는 제2단계; 상기 제2단계에서 연산된 평균값으로써 각 경계픽셀에 보간하여 출력하는 제3단계로 이루어진 것을 특징으로 하는 영상 확장시의 블럭킹 현상 방지 방법.
