Abstract
Official abstract text for this publication.
A unit pixel of a depth sensor includes a light-receiver configured to perform photoelectric conversion of an incident light to output an electrical signal and at least two sensors adjacent to the light-receiver to receive the electrical signal from the light-receiver such that a line connecting the sensors forms an angle greater than zero degrees with respect to a first line, the first line passing through a center of the light-receiver in a horizontal direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A unit pixel of a depth sensor, the unit pixel comprising: a body including a substrate and an isolation layer on the substrate, the body including a first surface, a second surface and a third surface, the second surface being arranged opposite to the third surface, the body including a trench extending from the second surface through the third surface, the trench being formed below the first surface of the body, the body further including a first ridge on…
