Abstract

본 발명은 캠코더의 손떨림 보정방법 및 보정장치에 관한 것으로, 종래 센서를 이용한 씨씨디 구동방식의 캠코더인 경우 외부에 센서를 부착해야 하므로 소형화로 구현할 수 없고, 메모리 제어방식의 경우 메모리의 전력소비가 센서에 비해 월등히 많아 축전지 전원을 사용할 경우 장시간 사용할 수 없는 문제점이 있었다.The present invention relates to a camera shake correction method and a correction device. In the case of a CD drive camcorder using a conventional sensor, a sensor must be attached to the outside so that it can not be miniaturized. There was a problem that can not be used for a long time when using the battery power much more than the sensor.

따라서 종래의 문제점을 해결하기 위하여 본 발명은 현재 프레임 신호와 전프레임 신호의 상관성을 이용하여 손떨림을 검출하고 씨씨디 구동제어방식으로 손떨림을 보정하여 캠코더의 부피를 줄이고 전력소비를 줄일 수 있도록 한다.Therefore, in order to solve the conventional problems, the present invention detects hand shake by using the correlation between the current frame signal and the previous frame signal, and compensates for the hand shake by the CD drive control method so as to reduce the volume of the camcorder and reduce power consumption.
