Abstract: In a range image sensor, a plurality of range sensors are disposed in a one-dimensional direction. The plurality of range sensors include a photogate electrode, first and second signal charge accumulating regions disposed on one side of the photogate electrode, third and fourth signal charge accumulating regions disposed on the other side, first transfer electrodes for making charge flow into the first and fourth signal charge accumulating regions in response to a first transfer signal, and second transfer electrodes for making charge flow into the second and third signal charge accumulating regions in response to a second transfer signal.

Abstract: A signal charge collecting region is disposed inside a charge generating region so as to be surrounded by the charge generating region, and collects signal charges from the charge generating region. An unnecessary charge collecting region is disposed outside the charge generating region so as to surround the charge generating region, and collects unnecessary charges from the charge generating region. A transfer electrode is disposed between the signal charge collecting region and the charge generating region, and causes the signal charges from the charge generating region to flow into the signal charge collecting region in response to an input signal. An unnecessary charge collecting gate electrode is disposed between the unnecessary charge collecting region and the charge generating region, and causes the unnecessary charges from the charge generating region to flow into the unnecessary charge collecting region in response to an input signal.
