Abstract

본 발명은 감시 비디오 카메라로부터 제공되는 영상 프레임의 녹화 동작을 보다 효율적으로 제어하도록 된 비디오 카메라의 녹화 제어장치에 관한 것으로, 비디오 카메라의 녹화장치에 있어서, 비디오 카메라로부터 입력되는 영상 프레임을 저장하며, 저장되는 영상 프레임의 입력 순위별로 영상 프레임 단위로 출력하는 선입선출 메모리와, 비디오 카메라로부터의 이전에 입력된 영상 프레임(N-1)과 비디오 카메라로부터의 현재 입력되는 영상 프레임(N)간의 움직임 오차값을 검출하는 움직임 검출부와, 움직임 검출부로부터 제공되는 두 프레임간의 움직임 오차값과 기설정된 움직임 오차값의 비교에 의거하여 선입선출 메모리로부터 출력되는 영상 프레임이 녹화장치로의 녹화 여부를 제어하는 녹화가 제어부로 구성됨으로써 감시 시스템에서의 저장 매체의 효율적인 이용이 가능하게 되며, 무의미한 기록을 제거할 수 있는 효과가 있다.The present invention relates to a recording control apparatus of a video camera configured to more efficiently control a recording operation of an image frame provided from a surveillance video camera, wherein the recording apparatus of the video camera stores an image frame input from the video camera, Motion error between the first-in first-out memory that outputs the image frame unit by the input order of the stored video frames, and the image frame N-1 previously input from the video camera and the image frame N currently input from the video camera. The motion detection unit for detecting a value and the video frame output from the first-in, first-out memory based on the comparison of the motion error value between the two frames provided from the motion detection unit and the predetermined motion error value are recorded. Storage in the monitoring system by means of a control unit Efficient use of the medium becomes possible, and there is an effect of eliminating meaningless recordings.
