Abstract: An imaging device includes a hardware processor coupled to a memory. The processor generates a video signal by imaging an observation target in an exposure state according with outside brightness of a vehicle measured by a sensor. The processor sets an imaging mode corresponding to an exposure state to be applied when performing imaging. The imaging mode is set on the basis of the outside brightness and a signal level of the video signal. The processor outputs a video signal obtained by performing imaging in the imaging mode.
