IMAGE PICKUP APPARATUS AND FILTER

摘要

This technique relates to an image-capturing device and filter capable of providing an image-capturing device capable of detecting infrared light or ultraviolet light and visible light at a time. An image-capturing device 1A includes a lens system 20 and an image-capturing unit 10 upon which light having passed through the lens system 20 is incident, wherein the image-capturing unit 10 includes a plurality of first image-capturing elements 11 configured to receive light in a first wavelength band and a plurality of second image-capturing elements 12 configured to receive light in a second wavelength band which is different from the first wavelength band, and wherein the lens system 20 or the image-capturing unit 10 is provided with an optical element 30A so that the light in the first wavelength band of which light quantity is less than the light quantity of the light in the second wavelength band reaches the image-capturing unit.
