Abstract

PURPOSE:To enable the fase signal generated through radiation of laser light of excessive intensity to be eliminated by adding a plurality of photo detectors which detect the incoming of flash in the upper part of a wide visual field optical system and taking the synchronization with the video signal of a solid state image sensing element. CONSTITUTION:A plurality of photo detectors 6 of silicon PIN type which detect the incoming of flash are added to the upper part of a wide visual field optical system 1 aside from a solid state image sensing element 2. Synchronization of the signals from said photo detectors 6 and the video signal of the solid state image sensing element 2 generated in a video signal generating circuit 3 is taken. These enable the false signal generated through radiation of laser light of excessive intensity to be eliminated. Here, 4 denotes a variable aperture, 5 an aperture adjusting mechanism, 7 an optical filter for limiting receiving wavelength bands and 8 a top cover for preventing the incidence of direct sunlight to the photo detectors 6.
