Document Type and Number:
WIPO Patent Application WO/2022/004572
Kind Code:
A1
Abstract:
Provided are a lens device, an imaging device, and an imaging method for suppressing overexposure by dimming or shielding total reflected light. The lens device (100) comprises: an optical system (100A); a wavelength polarizing filter unit (130) that is disposed at or near a pupil position of the optical system (100A) and that includes a plurality of optical filters in which a plurality of opening regions are arranged in a plurality of aperture regions and which include two or more optical filters for transmitting light having partially different wavelength bands, and a plurality of first polarizing filters which are arranged in the plurality of opening regions and include at least two first polarizing filters having different polarization directions; and a first circular polarizing optical element (101) located between a subject and the wavelength polarizing filter unit.
