Abstract
The disclosed apparatus controls the voltage of a camera power supply that drives a heavy load such as a motor. When the motor or other power consuming element is operated, a voltage step-up component supplies the camera's electronic circuitry with a stepped-up voltage. After the operation of the motor or other element is completed, operation of the voltage step-up component continues until the voltage of the power source achieves a predetermined value. Operation of the voltage step-up component then stops.
