Title:
SOLID-STATE IMAGE SENSOR AND DISTANCE DETECTOR USING THE SAME
Document Type and Number:
Japanese Patent JP2014123714
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a solid-sate image sensor capable of detecting a distance with high sensitivity and high accuracy, and a distance detector using the same.SOLUTION: A solid-sate image sensor 102 has a plurality of pixels, at least one of which has a plurality of photoelectric conversion parts 204 and 205, and a pupil division member 211 allowing light having entered a region defined by itself of light having passed through an exit pupil 104 to enter the plurality of photoelectric conversion parts. In the plurality of photoelectric conversion parts, a potential profile for electric charges changes in a vertical line direction of a substrate, and a distance between potential centroids on a cross section perpendicular to a vertical line of the plurality of photoelectric conversion parts is longer on a rear side on an opposite side than on the light incident side.
