    Abstract: The present embodiment relates to a distance sensor configured to inject an equal amount of current into storage nodes coupled, respectively, to charge collection regions where charges of a photosensitive region is distributed by driving of first and second transfer electrodes and obtain a distance to an object based on difference information on charge amounts of the respective storage nodes. Saturation caused by disturbance light of each storage node is avoided by injecting the equal amount of current to each storage node, and the difference information on the charge amounts of the respective storage nodes, which is not easily affected by the current injection, is obtained by driving the first and second transfer electrodes according to the plurality of frames representing the electrode drive pattern, respectively.

    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.
