Abstract: A dashboard camera according to one aspect of this embodiment includes: an event detection unit configured to detect an event that has occurred in an own vehicle; an imaging control unit configured to switch, when the event has been detected by the event detection unit, imaging conditions of an imaging apparatus that captures images of an area including the interior of the vehicle from imaging conditions appropriate for the environment inside the vehicle to imaging conditions appropriate for the environment outside the vehicle; and a recording control unit configured to cause a recording apparatus to record the video images captured by the imaging apparatus.

Abstract: Light emitted from a light source is irradiated to a reflective light modulator which modulates irradiated light to reflect based on image data and the light reflected by the light modulator is projected. A ratio of return light returning from the light modulator to the light source to the light irradiated to the light modulator is calculated based on the image data. A light amount of the light emitted from the light source is calculated by using the calculated ratio and a detection output of an optical sensor provided between the light source and the light modulator.
