ABSTRACT:
In an electronic camera that comprises image-producing element, a signal processing circuit for processing signals from the image-producing element, a record medium for recording signals from the signal processing circuit, a motor for driving the record medium, flash having a charging circuit, a power supply, and a controller for controlling the camera operation, the power to the motor is interrupted by the controller for the duration of time the charging circuit is being charged. In another embodiment, the power is interrupted to both the motor and the signal processing circuit by the controller for the duration of charging, so that a large charging current is available and the signal processing circuit is prevented from erroneous operation due to source voltage drops.
