SOLID-STATE IMAGE SENSOR AND IMAGING APPARATUS USING SAME

摘要

A solid-state image sensor provided with a plurality of pixels which photo-electrically convert an object image formed by an imaging optical system, wherein at least a portion of the plurality of pixels are ranging pixels in which a first photoelectric conversion unit, a barrier region and a second photoelectric conversion unit are provided in alignment in a first direction in this sequence; in the peripheral regions where are distanced from a straight line perpendicular to the first direction and passing through the center of the solid-state image sensor, for more than half of the ranging pixels, the barrier region is situated eccentrically in a direction parallel to the first direction.

1. A solid-state image sensor provided with a plurality of pixels which photo-electrically convert an object image formed by an imaging optical system, wherein
at least a portion of the plurality of pixels are ranging pixels in which a first photoelectric conversion unit, a barrier region and a second photoelectric conversion unit are provided in alignment in a first direction in this sequence; when the region of the solid-state image sensor is divided by a straight line perpendicular to the first direction and passing through the center of the solid-state image sensor, into a first region which is positioned in a negative direction of the first direction from the straight line, and a second region which is positioned in a positive direction of the first direction from the straight line; more than half of the ranging pixels in a portion of the first region which is distanced by at least a prescribed distance from the straight are first ranging pixels in which the center of a barrier region is situated eccentrically in the negative direction of the first direction with respect to the center of the ranging pixel; and more than half of the ranging pixels in a portion of the second region which is distanced by at least the prescribed distance from the straight line are second ranging pixels in which the center of a barrier region is situated eccentrically in the positive direction of the first direction with respect to the center of the ranging pixel.
