RANGE SENSOR AND RANGE IMAGE SENSOR
First Claim
1. A range sensor comprising:
- a charge generating region at which charges are generated in response to incident light;
at least two charge collecting regions arranged spatially apart from each other to collect the charges from the charge generating region; and
a transfer electrode which is installed at each periphery of the charge collecting region, given a charge transfer signal different in phase, and surrounding the charge collecting region.

Abstract
The range image sensor is a range image sensor which is provided on a semiconductor substrate with an imaging region composed of a plurality of two-dimensionally arranged units (pixel P), thereby obtaining a range image on the basis of charge quantities QL, QR output from the units. One of the units is provided with a charge generating region (region outside a transfer electrode 5) where charges are generated in response to incident light, at least two semiconductor regions 3 which are arranged spatially apart to collect charges from the charge generating region, and a transfer electrode 5 which is installed at each periphery of the semiconductor region 3, given a charge transfer signal different in phase, and surrounding the semiconductor region 3.
