Abstract
A three-dimensional input device including a light projecting device for projecting detection light, and an image sensing device for receiving the detection light reflected by an object and converting the received light to electrical signals. The detection light is controlled so as to scan the object periodically while changing the projection direction of the detection light, and to consecutively perform a plurality of scans at mutually different detection light projection angles in accordance with the predefined specifications at the start of operation.
