ABSTRACT:
The shutter release button operation is interrupted and a warning is given when the shutter release button is depressed in an excessively quick action which may cause camera shake, to prevent faulty photographing. In addition, with provision of a voltage reference function, irregular shutter operation can be prevented by locking the shutter in case the voltage of the power source has dropped under a prescribed level. Simply composed, the system is applicable to the shutter without difficulty.
