Abstract
In a sensing device that generates a distance image, a variation in distance measurement accuracy in the distance image is reduced. The sensing device includes a predetermined number of pixel circuits and a voltage control unit. Each of the predetermined number of pixel circuits includes a photoelectric conversion element and a detection circuit. A predetermined reverse bias voltage is applied between an anode and a cathode of the photoelectric conversion element. The detection circuit detects whether a photon is present or absent on the basis of a potential of either the anode or the cathode. The voltage control unit adjusts the reverse bias voltage to a value corresponding to a breakdown voltage of the photoelectric conversion element for each of the pixel circuits.
