Claims (2)
- 영상의 휘도신호를 소정의 크기를 갖는 블럭으로 분할하고, 현재 영상의 어떤 블럭과 가장 비슷한 이전 영상의 블럭을 찾아 이때의 이동거리를 움직임벡터로 산출하는 움직임 평가방법에 있어서, 현재 영상의 어떤 블럭에 대하여 휘도신호의 평균값을 산출하는 과정; 이전 영상의 움직임평가가 적용되는 블럭에 대하여 휘도신호의 평균값을 산출하는 과정; 상기 두 평균값이 동등한 수준이 되도록 이전 영상의 움직임평가가 적용되는 블럭의 휘도신호를 보정하는 과정; 그리고 현재 영상의 블럭과 이전 영상의 움직임 평가가 적용되는 블럭에 대하여 각 화소의 휘도신계의 차를 합한 것이 가장 작은 블럭을 선택하고 이들 간의 이동거리를 움직임벡터로서 산출하는 과정을 포함하는 움직임 평가방법.
- 제1항에 있어서, 상기 휘도신호를 보정하는 과정은 상기 두평균값의 차(H)를 이전 영상의 움직임 평가가 적용되는 블럭의 화소값마다에 더해주는 것을 특징으로 하는 움직임 평가방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
