Patent ID: 7999217

Claim:
An image-capturing element comprising: a pair of photoelectric conversion cells that pupil-divide object light in a first direction and in a second direction, the first direction and the second direction being different from each other, and that output a ranging signal, wherein each of the pair of photoelectric conversion cells includes a photoreceiving element configured to receive the object light and generate a ranging signal, a first light-shielding layer having a first light-transmitting area, the first light-shielding layer being arranged above the photoreceiving element, and a second light-shielding layer having a second light-transmitting area, the second light-shielding layer being arranged between the photoreceiving element and the first light-shielding layer, and wherein the pair of photoelectric conversion cells includes a first photoelectric conversion cell in which the first light-transmitting area is offset in the first direction on the first light-shielding layer and the second light-transmitting area is offset in the second direction on the second light-shielding layer, and a second photoelectric conversion cell in which the first light-transmitting area is offset in the second direction on the first light-shielding layer and the second light-transmitting area is offset in the first direction on the second light-shielding layer, wherein in the first photoelectric conversion cell, the first light-transmitting area is provided in such a manner as to be offset in the first direction by using the vicinity of the center of the photoelectric conversion cell as an origin, and the second light-transmitting area is provided in such a manner as to be offset in the second direction by using the vicinity of the center as an origin, and in the second photoelectric conversion cell, the first light-transmitting area is provided in such a manner as to be offset in the second direction by using the vicinity of the center of the photoelectric conversion cell as an origin, and the second light-transmitting area is provided in such a manner as to be offset in the first direction by using the vicinity of the center as an origin.
