Claim:
An imaging device comprising: an imaging element for receiving light from a subject and converting the light to an electric signal; a video signal processing circuit for performing signal processing on a video signal generated based on the electric signal; a power supply circuit for supplying power to the video signal processing circuit; a signal detection unit for receiving a backup lamp signal indicating light-on or light-off of a backup lamp from the backup lamp installed at a back part of a vehicle; and a power supply control unit for controlling the power supply circuit based on the backup lamp signal so that the supply of power is turned ON in response to receipt of the backup lamp signal indicating the light-on of the backup lamp and is kept turned ON thereafter during a remaining time of light-on of the backup lamp and for at least a preset time after receipt of the backup lamp signal indicating a next light-off of the backup lamp such that the power is supplied to the video signal processing circuit so as to enable the signal processing on the video signal to be performed (i) after the receipt of the backup lamp signal indicating the light-on of the backup lamp and (ii) during at least the preset time after receipt of the backup lamp signal indicating the backup lamp is light-off, and the supply of power is turned OFF thereafter.
