LENS DEVICE, IMAGING DEVICE, OPTICAL MEMBER, IMAGING METHOD, AND IMAGING PROGRAM

WIPO Patent Application WO/2021/153473

A1

One embodiment of the present invention provides a lens device, an imaging device, an optical member, an imaging method, and an imaging program for acquiring a multi-spectrum image having excellent image quality. According to one aspect, the lens device comprises an imaging optical system including a lens that forms an optical image of a subject, and an optical member positioned near the pupil of the imaging optical system in a state where the optical axis of the optical member matches the optical axis of the imaging optical system, the optical member having: a frame provided with a plurality of opening regions, a plurality of optical filters positioned in at least one of the plurality of opening regions, the plurality of optical filters including two or more optical filters that transmit lights for which at least part of the wavelength bands differ from each other; and a plurality of polarization filters positioned in at least one of the plurality of opening regions, the plurality of polarization filters having different polarization directions. The quantity of light emitted from the imaging optical system can be modified with respect to the plurality of opening regions.
