IMAGING APPARATUS, IRIS DEVICE, IMAGING METHOD, AND PROGRAM

摘要

The present disclosure relates to an imaging apparatus, an iris device, an imaging method, and a program that are capable of performing multispectral imaging in a small mechanism. The imaging apparatus includes: an image sensor that captures an image of a subject; an optical system that forms an image on the image sensor with light from the subject; and an iris mechanism that restricts the amount of light passing through the optical system. The iris mechanism includes aperture blades that adjust a size of an aperture causing the light from the subject to pass through the aperture, and an optical filter that is provided to at least one of the aperture blades and transmits light having a predetermined wavelength. The aperture blades are driven to positions where the aperture has a predetermined size, in a state where the optical filter provided to the at least one of the aperture blades is hidden by one of the aperture blades other than the aperture blade of the optical filter. The aperture blades provided with predetermined optical filters are driven such that the predetermined optical filters sequentially cover the aperture at predetermined timings. The present technology can be applied to, for example, an imaging apparatus including an iris mechanism.
