Patent ID: 11726389

Abstract:
Provided are a lens device, an imaging apparatus, an optical member, an imaging method, and an imaging program that are used to acquire multispectral images having a good image quality. According to one aspect, a lens device includes: an imaging optical system that includes a lens forming an optical image of a subject; and an optical member that is disposed near a pupil of the imaging optical system in a state where an optical axis of the optical member coincides with an optical axis of the imaging optical system, and includes a frame that includes a plurality of aperture regions, a plurality of optical filters that are disposed in at least one of the plurality of aperture regions and include two or more optical filters transmitting light having at least some wavelength ranges different from each other, and a plurality of polarizing filters that are disposed in at least one of the plurality of aperture regions and have different polarization directions. The amount of light emitted from the imaging optical system is changeable in the plurality of aperture regions.
