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 detection system, which is capable of, even when detecting spatial information from a common target space by use of a plurality of detection devices, achieving accurate detection without causing interference between the detection devices. Each of the detection devices has a light emitting source for projecting light intensity-modulated with a modulation period into the target space, a photodetector for receiving light from the target space, and an evaluation portion for detecting the spatial information of the target space from a change between the light projected from the light emitting source and the light received by the photodetector. The system includes a timing control portion for controlling the timings of projecting the lights from the light emitting sources such that a light projection period of the light emitting source of one of the detection devices does not overlap with the light projection period of the light emitting source of another detection device.

摘要： A spatial information detection device is provided, which is capable of, even under the condition that an environmental light having intensity fluctuations exists in a target space, projecting a light intensity-modulated with a predetermined modulation signal from a light emitting source into the target space, receiving light from the target space with a photodetector, and detecting spatial information of the target space from a change between the light projected from the light emitting source and the light received by the photodetector. This device has a smoothing unit configured to integrate, over a predetermined integration period, a fluctuation component in a prescribed phase zone of the modulation signal with respect to an electric charge amount generated by receiving the environmental light in the electric charge amount generated at the photodetector by receiving the light from the target space, thereby smoothing the fluctuation component.
