Abstract
An electronic camera free from failures of an internal circuit, such as a signal processing portion, caused by a drop in battery voltage when there remains a small amount of electric charge in the battery, includes a signal processing portion for signal-processing an imaged video signal obtained from an imaging element to form image data, a monitor for displaying the image data, an electronic flash device, a battery for supplying current to the signal processing portion, the monitor and the electronic flash device, a battery voltage detector circuit, and a system controller. The electronic flash device includes a capacitor charged when no light is emitted, and a discharged tube receiving an output from the capacitor and emitting light. The system controller receives an output from the battery voltage detector circuit, determines whether the amount of electric charge remaining in the battery is below a predetermined value, and controls displaying on the monitor and charging of the capacitor not to be simultaneously performed when the amount of electric charge remaining in the battery is below the predetermined value.
