Abstract
A solid-state imaging sensor provided with a plurality of pixels which convert an object image formed by an imaging optical system into an electrical signal, at least a part of the pixels being ranging pixels in which a first and a second photoelectric conversion unit are provided in alignment in a first direction, and in more than half of the ranging pixels in one of peripheral region of the solid-state sensor, the capacitance of the first photoelectric conversion unit being greater than the capacitance of the second photoelectric conversion unit; and in more than half of the ranging pixels in the other of peripheral region of the solid-state sensor, the capacitance of the second photoelectric conversion unit being greater than the capacitance of the first photoelectric conversion unit.

A solid-state imaging sensor provided with a plurality of pixels which convert an object image formed by an imaging optical system into an electrical signal,
- at least a portion of the plurality of pixels being ranging pixels in which a first photoelectric conversion unit and a second photoelectric conversion unit are provided in alignment in a first direction, and
- when a region of the solid-state imaging sensor is divided into a first region and a second region by a straight line perpendicular to the first direction and passing through the center of the solid-state imaging sensor;
- then in more than half of the ranging pixels in a region of the first region that is distanced by no less than a predetermined distance from the straight line, a surface area in an imaging plane of the first photoelectric conversion unit is greater than a surface area in an imaging plane of the second photoelectric conversion unit;
- and
- in more than half of the ranging pixels in a region of the second region that is distanced by no less than a predetermined distance from the straight line, the surface area in the imaging plane of the second photoelectric conversion unit is greater than the surface area in the imaging plane of the first photoelectric conversion unit.
