Beschreibung
Zusammenfassung:	A camera apparatus includes: an imaging device; a polarization filter that transmits a polarization component; an infrared ray cut filter that cuts infrared rays; a first motor that rotates the polarization filter; and a second motor that inserts any one filter of the polarization filter and the infrared ray cut filter in an imaging region of the imaging device. The infrared ray cut filter cuts the infrared rays among light beams incident on the imaging device when the infrared ray cut filter is inserted in the imaging region by the second motor, and the polarization filter that is rotated by the first motor transmits the polarization component among the light beams incident on the imaging device when the polarization filter is inserted in the imaging region by the second motor.
