Provided is an image capturing system, including an image capturing section that includes a plurality of first light receiving elements that receive light in a specified wavelength region and light in a first wavelength region, which is different from the specified wavelength region, and a plurality of second light receiving elements that receive light in the specified wavelength region and light in a second wavelength region, which is different from the specified wavelength region; and a control section that controls a spectrum of the light received by the plurality of first light receiving elements and the plurality of second light receiving elements. The control section, at a first timing, causes the plurality of first light receiving elements to receive light in a wavelength region including the first wavelength region from a subject and causes the plurality of second light receiving elements to receive light in a wavelength region including the second wavelength region from the subject and, at a second timing, causes the plurality of first light receiving elements and the plurality of second light receiving elements to receive light in a wavelength region including the specified wavelength region from the subject.
