The filter unit has a plurality of opening portions including a first opening portion and a second opening portion. At least the first opening portion and the second opening portion each include a band-pass filter, and each include an optical element on at least one of an object side or an image side of the band-pass filter. The optical element is composed of a polarized light filter and a wave plate which converts linearly polarized light into circularly polarized light or elliptically polarized light. The first opening portion and the second opening portion pass light in different wavelength regions and different polarization directions.
