Abstract
A range image acquisition device includes: a light source; a light source control unit controlling the light source; a pixel array including a plurality of pixel circuits; and a peripheral circuit supplying control pulses for controlling an operation of the pixel array, a logic pulse and an inverted signal of the logic pulse to the pixel array. The light source control unit repeatedly performs an operation of generating the pulsed light so that the incident pulsed light based on the pulsed light is incident on a sensitive pixel region in the pixel array while moving in a sensitive pixel region. The peripheral circuit allows the pixel circuits to move the electric charges generated in the photoelectric conversion region to the charge discharging region for the pixel circuits constituting an insensitive pixel region, not included in the sensitive pixel region.
