Abstract
In a video camera in strobe mode, when a condition for strobe light emission is ready, the aperture of an iris is reduced and the gain of an AGC amplifier is fixed at a predetermined value. Accordingly, a dark image representing the condition ready for strobe light emission is displayed on an electronic view finder, and in addition saturation of charge accumulation is prevented.
