피사체의 움직임 검출에 따른 촛점조절제어전압(Fcon)을 발생시켜 촛점조절모터(14)를 구동시키는 자동촛점조절부(10)의 상기 촛점조절제어전압(Fcon)을 디지탈 신호로 변환하는 아날로그/디지탈변환기(22)와, 그 아날로그/디지탈변환기(22)와, 그 아날로그/디지탈변환기(22)의 출력을 현재값으로 저장하는 제1레지스터(23)와, 이전값을 저장하는 제2레지스터(25)와, 상기 제1레지스터(23)의 현재값과 제2레지스터(25)의 이전값을 비교하여 같지 않을 경우에 피사체 움직임 검출신호를 발생하여 시스템제어마이컴(21)에 인가시키는 비교부(21)와, 그 비교부(26)의 현재값과 1이전값이 같지않을때의 제어신호에 따라 상기 제1레지스터(23)의 현재값을 상기 제2레지스터(26)의 이전값으로 저장하게하는 게이트(24)를 구비하여 상기 마이컴(21)이 피사체 움직임 검출시만 녹화수행을 하게 기록/재생장치(27)를 제어하도록 구성하여 된 것을 특징으로 하는 감시용 카메라의 녹화제어장치.Analog to convert the focus control control voltage (F con ) of the automatic focus control unit 10 for driving the focus control motor 14 by generating a focus control control voltage (F con ) according to the movement of the subject to a digital signal / Digit converter 22, its analog / digital converter 22, a first register 23 for storing the output of the analog / digital converter 22 as a current value, and a second register for storing a previous value. And a comparison unit for generating a subject motion detection signal and applying it to the system control microcomputer 21 when the current value of the first register 23 and the previous value of the second register 25 are not the same. (21) and storing the current value of the first register 23 as the previous value of the second register 26 in accordance with a control signal when the present value of the comparator 26 and the previous value are not the same. The gate 24 to allow the microcomputer 21 to detect the movement of the subject only. The recording control device of the camera for monitoring, characterized in that the to and to control the screen performs a recording / reproducing apparatus 27 to the. 자동촛점조절제어전압(Fcon)이 변화에 따라 피사체의 움직임검출제어 신호를 인가받는 마이컴(21)이 피사체의 움직임검출시 기록/재생장치(27)를 제어하여 녹화수행을 하게하고, 녹화수행중에 피사체의 움직임이 정지될 때 소정의 설정시간동안 녹화모드를 유지하면서 그 설정시간내에 피사체의 움직임이 검출되지 않으면 움직임이 검출될때까지 녹화일시정지제어를 하도록 하는 것을 특징으로 하는 감시용 카메라의 녹화제어방식.As the autofocus control voltage F con changes, the microcomputer 21, which receives the motion detection control signal of the subject, controls the recording / reproducing apparatus 27 to perform recording by detecting the movement of the subject. When the movement of the subject is stopped during the recording mode for a predetermined set time, if the movement of the subject is not detected within the set time, recording pause control until the movement is detected Control method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
