Abstract
본 발명은 복수개의 카메라를 연결했을 경우의 영상 동기 장치에 관한 것으로, 상세하게는 3판식 CCD를 사용하는 방송용 카메라, 캠코더, 디지털 스틸 카메라 등과 같은 제품이나, 이와 같이 여러대의 카메라를 동시에 연결하여 감시 기능을 수행하는 감시 시스템 등의 영상 동기 장치에 관한 것이다.The present invention relates to a video synchronization device when a plurality of cameras are connected, and more particularly, a product such as a broadcasting camera, a camcorder, a digital still camera, etc. using a three-plate CCD, or a plurality of cameras connected in this manner to monitor the same. A video synchronization device such as a surveillance system that performs a function.
즉, 본 발명에 따른 복수개 카메라의 영상 동기 장치는 독립적인 각각의 단위 카메라에 각각 별도의 타이밍신호 발생기를 마련하여 하나의 발진기에서 발생된 발진 클럭과 각 동기 신호 발생기에서 생성된 텔리비젼 동기 펄스를 공급하고, 각 동기 신호 발생기의 신호 생성을 위해서 발진기 클럭의 1/2 분주 클럭을 각각 공급하는 구성을 함으로써, 즉 타이밍 신호 발생기에 공급되는 클럭을 각 카메라에 공통으로 사용하고, 동기 신호 발생기에 공급되는 클럭을 각 단위 카메라에 동일상(PHASE)의 클럭으로 공급함으로써, 다른 부수적인 회로의 추가 없이 여러 대의 카메라를 간편하게 구동할 수 있는 장점이 있다.That is, the apparatus for synchronizing a plurality of cameras according to the present invention provides a separate timing signal generator for each independent unit camera to supply an oscillation clock generated by one oscillator and television synchronization pulses generated by each synchronization signal generator. By supplying 1/2 divided clocks of the oscillator clocks to generate the signals of the respective synchronization signal generators, that is, the clocks supplied to the timing signal generators are commonly used for the respective cameras, and are supplied to the synchronization signal generators. By supplying the clock to each unit camera in the same phase (PHASE), there is an advantage that can easily drive a plurality of cameras without the addition of additional circuitry.
