감시용 카메라의 녹화 모드를 설정한 상태에서 스위칭 기능을 통해 1필드의 영상신호를 메모리에 저장하고, 일정시간 후 스위칭 기능을 통해 1필드 영상신호를 다른 메모리에 저장하고, 상기 저장된 두 영상신호의 상관성을 검출한 후 레벨을 검출하여, 상기 두 영상신호가 같으면 상기 영상신호의 저장 및 상관성검출기능을 반복 수행하면서 녹화정지기능을 수행하고, 상기 두 영상신호가 다르면 녹화기능을 수행하는 것을 특징으로 하는 감시용 카메라의 필드 메모리를 이용한 녹화방법.With the recording mode of the surveillance camera set, the video signal of one field is stored in a memory through a switching function, and after a predetermined time, the one field video signal is stored in another memory through a switching function, and the two video signals are stored. After detecting the correlation, the level is detected. If the two video signals are the same, the recording stop function is repeatedly performed while the storage and correlation detection functions are repeatedly performed. If the two video signals are different, the recording function is performed. Recording method using the field memory of the surveillance camera. 카메라 영상처리부(42)의 출력 영상신호가 영상처리계(43), 서보계(44)에 인가되며, 시스템제어부(26)의 출력이 상기 서보계(44), 메카니즘계(47)를 제어하며 녹화기능을 수행되게 구성한 카메라의 녹화장치에 있어서,상기 출력영상신호가 동기분리기(13)를 통해 콘트롤 신호처리부(16), 리드/라이트타이밍콘트롤러(15)를 구동한 후 메모리 콘트롤러(17)를 통해 어드레스발생기(19)를 제어 하고, 스위치(12), A/D변환기(14)를 제어하여 상기 출력 영상신호를 데이터처리부(18)에 인가하게한 카메라녹화제어부(51)와, 상기 어드레스발생기(19)의 어드레스지정에 따라 상기 데이터처리부(18)의 출력 데이타가 메모리(24)(25)에 각각 저장되게한 메모리부(52)와, 상기 메모리부(52)의 출력이 상관성제어부(20)의 제어를 통해 상관성 검출기(21)에 인가되어 상관성을 검출한 후 레벨검출기(22)를 통과하고, 비교기(23)를 통해 상기 상관성제어부(20)의 기준치와 비교한 후 상기 시스템 제어부(26), 절환 스위치(27)를 제어하여 상기 영상처리계(43)의 녹화기능을 제어하게 한 상관성 검출부(53)로 구성하여 된 것을 특징으로 하는 감시용 카메라의 필드 메모리를 이용한 녹화장치.The output image signal of the camera image processor 42 is applied to the image processor 43 and the servo system 44, and the output of the system controller 26 controls the servo system 44 and the mechanism system 47. In the recording apparatus of the camera configured to perform the recording function, the output image signal is driven through the synchronous separator 13 to drive the control signal processing unit 16, the read / write timing controller 15 and then the memory controller 17 A camera recording controller 51 which controls the address generator 19 and controls the switch 12 and the A / D converter 14 to apply the output image signal to the data processor 18, and the address generator According to the address designation (19), the memory unit 52 which causes the output data of the data processing unit 18 to be stored in the memory 24 and 25, respectively, and the output of the memory unit 52 are the correlation control unit 20. Level after being applied to the correlation detector 21 through the control of After passing through the outlet 22 and comparing the reference value of the correlation controller 20 through the comparator 23, the system controller 26 and the switching switch 27 are controlled to record the image processing system 43. A recording apparatus using the field memory of a surveillance camera, characterized by comprising a correlation detector (53) for controlling a function. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
