IMAGE CAPTURING APPARATUS HAVING A FILTER SECTION DISPOSED ON PERIPHERY OF A LIGHT PASSING SECTION OF A PARTIAL WAVELENGTH SPECTRUM DIAPHRAGM SECTION (AS AMENDED)

An image capturing apparatus is provided that simultaneously captures a visible light image and an infra-red light image in which the same subject is in focus. The image capturing apparatus includes a light receiving section that receives light from a subject; a partial wavelength spectrum diaphragm section that is disposed between the subject and the light receiving section and that includes a light passing section that allows light in a first wavelength spectrum and light in a second wavelength spectrum to pass through and a filter section, which is disposed on a periphery of the light passing section, that allows the light in the first wavelength spectrum to pass through but does not allow the light in the second wavelength spectrum to pass through; and an image generating section that generates a first image based on the light in the first wavelength spectrum received by the light receiving section via the light passing section and the filter section and generates a second image based on the light in the second wavelength spectrum received by the light receiving section via the light passing section.
