Abstract: An imaging device includes: a mechanical shutter; a shutter driver that operates the mechanical shutter in a continuous shooting mode and a single shooting mode; a driving electric power supplier; and an undercut controller (undercut/driving electric power controller) that stops operation of the imaging device when a power supply voltage becomes lower than a predetermined undercut voltage. In the single shooting mode, the driving electric power supplier lowers a driving electric power and the undercut controller stops operation of the imaging device at a lower undercut voltage.

Abstract: An imaging apparatus which can be mounted with a first battery and a second battery includes: a load circuit configured to operate the imaging apparatus; and a control circuit configured to control power supply to the load circuit based on a first battery voltage in the first battery and a second battery voltage in the second battery. In a high-load mode, the control circuit selects any one of the first battery, the second battery, and a combination of the first and second batteries in accordance with the first and second battery voltages, to supply power to the load circuit. In a low-load mode, the control circuit selects either one of the first battery and the second battery in accordance with the first and second battery voltages without selecting the combination of the first and second batteries, to supply power to the load circuit.
