Abstract

PURPOSE:To prevent the lens iris from being fully opened at every waiting state, by storing the amplitude of video signal immediately before the waiting state and using it as the control signal of lens iris. CONSTITUTION:When a quick start switch 11 is OFF and made to a waiting state, the memory control switch 16 is simultaneously OFF, the amplitude of video signal immediately before is stored in the memory circuit 6, the signal of stored value is input from a memory circuit 15 to a servo-amplifier circuit 6, and since the state of lens iris 8 is kept as it is in the state immediately before the waiting, the lens iris 8 is not fully open. By operating the memory switch 16 so that it is delayed by required leading time for the change from the waiting state of an image sensor 1 to the operating state, unnecessary switching operation of the lens iris 8 can be prevented.
