摘要： A range image sensor comprising a light source, a light detecting element, a sensor control stage and an image construction stage. The image construction stage calculates a distance value for each image element in a range image based on each electric charge picked up after a specific detection period of different detection periods by the sensor control stage, and then constructs the range image. The specific detection period is one of one or more detection periods during which the light detecting element does not reach saturation, and is one detection period during which a value related to the quantity of light received from the object space becomes maximum of that of the one or more detection periods.

摘要： A spatial information detecting device is provided, which is capable of reducing the possibility that a saturation phenomenon is caused by the influence of an environmental light. This device includes a photoelectric converting portion for receiving a signal light from a target space to generate electric charges, a charge separating portion for separating electric charges corresponding to a constant amount of a bias component as undesired electric charges from the electric charges generated by the photoelectric converting portion, a charge accumulating portion for accumulating the remaining electric charges as effective electric charges reflecting a fluctuation component of the signal light, a barrier control electrode for forming a potential barrier between the charge separating portion and the charge accumulating portion, and a charge take-out portion for outputting the effective electric charges as an received-light output. By controlling a voltage applied to the barrier control electrode to change a height of the potential barrier, it is possible to adjust an amount of electric charges flowing from the charge separating portion into the charge accumulating portion over the potential barrier.

摘要： A photodetector is provided, which has the capability of preventing a reduction in dynamic range for a signal light even under a plenty of environmental light to stably obtain a received light output. This photodetector has an accumulation electrode and a holding electrode, which are formed on a photoelectric converting portion through an insulating layer, and a control unit for controlling timings of applying voltages to these electrodes and polarities of the voltages. One of electrons and holes generated in the photoelectric converting portion is accumulated in an accumulation region formed by applying the voltage to the accumulation electrode, and the other is accumulated in a holding region formed by applying the voltage to the holding electrode. Then, the electrons and holes accumulated in the accumulation region and the holding region are recombined, so that remaining electrons or holes not recombined are output.
