摘要： A technology of a phase-difference detecting image pickup element that can precisely perform focus detection even if the position of an exit pupil with respect to the image pickup element changes is provided. The image pickup element of an image pickup device includes an AF pixel pair 11g that receive an object light beam transmitted through a pair of portion areas Qc and Qd whose areas become the same in an exit pupil at a position of distance Hm from the image pickup element. The AF pixel pair 11g includes light-intercepting portions 131 and 132 where respective light-transmitting portions that define the pair of portion areas Qc and Qd are provided. In addition, the image pickup element also includes a different AF pixel pair whose disposition of light-intercepting portions 131 and 132 are made different so that the areas of the pair of portion areas in the exit pupil at a position of a distance Hm from the image pickup element are the same. By this, even if the position of the exit pupil is changed by, for example, a lens replacement, the focus detection can be precisely performed by a phase-difference detection method by selecting a pixel pair in accordance with the position of the exit pupil.

摘要： 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.
