RANGE IMAGE ACQUISITION DEVICE

A range image acquisition device 1 includes: a light source 11 generating a pulsed light L; a light source control unit 12a controlling the light source 11; a pixel array 14 including a plurality of pixel circuits 13 generating electric charges corresponding to an incident pulsed light L; and a peripheral circuit 31 supplying control pulses G to G and G for controlling an operation of the pixel array 14, a logic pulse E, and an inverted signal of the logic pulse E to the pixel array 14. The light source control unit 12a repeatedly performs an operation of generating the pulsed light L so that the incident pulsed light L based on the pulsed light L is incident on a sensitive pixel region AE in the pixel array 14 while moving in a sensitive pixel region AE. The peripheral circuit 31 allows the pixel circuits 13 to move the electric charges generated in the photoelectric conversion region 21 to the charge discharging region 23 for the pixel circuits 13 constituting an insensitive pixel region AN, not included in the sensitive pixel region AE.
