Abstract
A capturing camera has a lens block that includes a lens for focusing light from a vehicle as a subject, an image sensor that captures an image based on light from the vehicle focused by the lens, a filter unit that rotatably supports a polarization filter which limits the light from the vehicle received by the image sensor, a sensor that detects a daytime mode or a night mode, a processor that disposes the polarization filter on a front side of the image sensor in the daytime mode, and disposes a band pass filter on the front side of the image sensor in the night mode, and an illuminator that irradiates the subject with IR light in the night mode. The filter unit switchably supports the polarization filter and the band pass filter that transmits the IR light.
