Abstract

줌인(zoom in)이나 줌아웃(zoom out) 동작에서 효율적으로 영상의 움직임을 추정하는 방법이 개시된다.A method of efficiently estimating the motion of an image in a zoom in or zoom out operation is disclosed.

본 발명에 따른 움직임 추정방법은 움직임 추정의 대상이 되는 기준화면과 참고화면의 줌비율을 검출하는 과정; 검출된줌비율에 상응하여 기준화면을 확대하거나 축소하는 과정; 및 상기 확대/축소과정에의해 결과된 화면에 근거하여 움직임을 추정하는 과정을 포함함을 특징으로 한다.According to an aspect of the present invention, there is provided a motion estimation method comprising: detecting a zoom ratio between a reference screen and a reference screen, which are objects of motion estimation; Enlarging or reducing the reference screen in correspondence with the detected zoom ratio; And estimating a motion based on the screen resulting from the enlargement / reduction process.

본 발명에 따른 움직임 추정방법은 기준화면을 줌비율에 따라 확대 또는 축소시킨 후 움직임 추정을 수행함으로써 줌인혹은 줌아웃된에서도 정확하게 움직임 추정을 수행할 수 있게 하는 효과를 갖는다.The motion estimation method according to the present invention has an effect of accurately performing motion estimation even when zoomed in or zoomed out by performing motion estimation after the reference screen is enlarged or reduced according to the zoom ratio.
