Abstract
Provided is an imaging device that is able to obtain a clear image in a relatively long distance in an environment of precipitation. A rainy weather camera includes: a light source that emits pulse light; a fan-shaped pulse light radiation unit that performs scanning in one direction with the pulse light emitted by the light source, spreads, in a direction perpendicular to the scanning direction, the pulse light for the scanning when the scanning is performed, and radiates the pulse light, which is in a state of being polarized in the direction perpendicular to the scanning direction, to an object; an imaging unit that receives reflection light from the object and performs exposure to a pixel; and a polarization filter that transmits light that is included in the reflection light received by the imaging unit and polarized to be parallel to the scanning direction. The imaging unit performs exposure only to a pixel which is synchronized with the scanning with the pulse light.
