Abstract
An image-capturing element includes a group of first pixels configured to receive object light and generate an image signal representing an object image; and a group of second pixels configured to receive the object light and generate a ranging signal for detecting a phase difference. The second pixels each include an optical filter on a light-receiving side thereof. The optical filter allows visible light in a wavelength range wider than a wavelength range of visible light that is allowed by a green primary-color filter to be transmitted therethrough within the object light to be transmitted therethrough.
