An imaging device is provided with a first substrate that includes a plurality of first pixels and a plurality of second pixels, a second substrate which includes a plurality of third pixels, and which faces the first substrate, and a processing unit that generates a signal. The plurality of third pixels receives light transmitted through the plurality of first pixels. The plurality of first pixels outputs signals corresponding to the wavelength band including the wavelength of green light, and allows the wavelength band including the wavelength of red light to be transmitted. The plurality ofsecond pixels outputs signals corresponding to the wavelength band including the wavelength of blue light but not including the wavelength of red light or the wavelength of green light. The pluralityof third pixels outputs signals corresponding to the wavelength band including the wavelength of red light.
