PURPOSE:To utilize effectively stroboscopic light by controlling the timing of light emission of a stroboscope, and containing the whole light emittion quantity of once of the stroboscope in one field or one frame scanning period. CONSTITUTION:An operation by a shutter release button 32 of an operating part is detected by a detecting circuit 50, and this detecting signal is supplied to a sequence circuit 52. A camera controlling circuit 54 supplies a TV signal to a transfer gate signal detecting circuit 56 for displaying a start of a frame or field scanning period and obtains a gate output signal. This gate output signal is supplied to the sequence circuit 52, and when it coincides with said release detecting signal, a timing signal is generated. On the other hand, when the release detecting signal is supplied to the sequence circuit 52, it is supplied immediately to an irradiate-diagnosing light cutting off circuit 58, and an irradiate-diagnosing lamp of a light source device is de-energized. As a result, a good stroboscopic photographing can be attained in a dark body cavity.
