Abstract
A light source unit, a light receiving unit including a distance image sensor in which a plurality of pixels are arranged and a pixel driving circuit, and a distance calculation unit calculating a distance to a subject based on electric charge amount accumulated in each of the charge accumulation units are provided, and a relationship between the emission timing and the accumulation timing is set such that electric charges corresponding to reflected light of the optical pulse reflected from the subject is accumulated in any of the three or more charge accumulation units provided in the pixels, and the distance calculation unit calculates the distance to the subject by using the same calculation equation regardless of which two charge accumulation units, in which electric charges are successively accumulated, among the three or more charge accumulation units provided in the pixels accumulate the electric charges corresponding to the reflected light.
