Abstract
A range imaging device includes a light-receiving unit including at least one pixel circuit including a photoelectric conversion element that generates charge in response to incident light, N (N≥3) charge storage units that integrate charge in a frame cycle, and transfer transistors, and a pixel drive circuit that causes the transfer transistors to distribute charge to the charge storage units with integration timing synchronizing with light pulses, a light source unit that emits light pulses; a range image processing unit that calculates a distance to an object based on integrated charges, and a measurement control unit that calculates a thinning time of not integrating charge, according to integrated charge in the charge storage units, the distance, and intensity of the incident light. The measurement control unit controls integration of charge with a thinning time set in a measurement zone corresponding to the distance from the light-receiving unit.
