Abstract

본 발명은 캠코더의 화면 안정화에 관한 것으로, 일반적으로 사용되고 있는 기존의 캠코더의 손 떨림 보상회로는 마이크로 프로세서에 퍼지의 기능을 도입하여 동화상에 의한 모션 벡터라고 간주된 어떤 구역의 모션 벡터를 전체 모션 벡터를 구하는 과정에서 제외시키게 되는데, 이러한 방법에서는 동화상에 의한 모션 벡터라고 간주되는 구역이 많을 경우 구해지는 전체 모션 벡터는 불확실하게 된다.The present invention relates to image stabilization of a camcorder, and a conventional camera shake compensation circuit employs a function of fuzzy in a microprocessor to convert a motion vector of a region, which is considered as a motion vector by moving images, to a full motion vector. In the method, the total motion vector obtained becomes uncertain when there are many regions considered as motion vectors by moving images.

이에 따라 본 발명은 상기와 같은 종래의 캠코더의 손 떨림 보정회로에 따르는 결함을 감안하여, 정지화상의 모션 벡터가 손떨림에 의한 것이라는 점과 정지화상 부분은 블러링 효과가 없어서 윤곽이 뚜렷하다는 것을 이용하여 작은 크기의 일정 구역의 윤곽의 합이 최대인 구역을 정지화상 구역으로 결정하여 모션 벡터를 구함으로써 캠코더의 손 떨림을 정확히 보상할 수 있도록 창안된 것이다.Accordingly, the present invention takes advantage of the above-described defects caused by the camera shake correction circuit of the conventional camcorder, and uses the fact that the motion vector of the still picture is caused by the hand shake, and that the still picture part has no blurring effect and has a clear outline. Therefore, it is designed to accurately compensate for camera shake by determining a motion vector by determining the area where the sum of the contours of a small sized area is the maximum as a still image area.
