Abstract

PURPOSE:To clearly photograph an object to be image-picked up at night by providing an illuminator to radiate infrared rays in the supervising area of a supervising camera, and interlocking the control of the illuminator to the CCD solid-state image pick-up element of the supervising camera in a home serucity system, etc. CONSTITUTION:A signal to control an exposure time is inputted from a clock/ synchronization signal generator 7 to a CCD driving timing circuit 8. Thus, a control signal to control an electric shutter 3a for a prescribed time is outputted from a CCD driving timing circuit 8. The control signal is also inputted to an infrared ray flash 9 arranged in a prescribed position, and interlocks with the opening action of the electric shutter 3a. Consequently, at the time of the lack of a light quantity at night, etc., the infrared rays are projected to the object to be image-picked up, the object to be image-picked up is image- formed to the CCD solid-state image pick-up element with a sufficient quantity, and the video of the object to be image-picked up can be projected as clearly as the video that photographed by an image multiplying tube on the screen of a television receiver.
