Abstract

Official abstract text for this publication.

In any three of three range sensors consecutively aligned in a one-dimensional direction, first signal charge-accumulating regions are adjacent to each other in the one-dimensional direction in the range sensor positioned in a center of the three range sensors and the range sensor positioned closer to one side of the one-dimensional direction than the range sensor positioned in the center of the three range sensors, and the first signal charge-accumulating region and the second signal charge-accumulating region are adjacent to each other in the one-dimensional direction in the range sensor positioned in the center of the three range sensors and the range sensor positioned closer to an another side of the one-dimensional direction than the range sensor positioned in the center of the three range sensors.

First claim
