Abstract: A distance measurement device includes a light projection unit for projecting light towards plural objects in different areas of a scene to measure respective distances to the objects. A photo-sensing unit receives reflected light from the different areas of the scene. Also provided is a processing unit which has a first mode and a second mode. The first mode is for measuring the respective distances to the objects based on a first photo-sense output of the photo-sensing unit corresponding to light projected to the different areas of the scene and reflected by the objects. The second mode is for judging, based on a second photo-sense output of the photo-sensing unit corresponding to light projected to a specific area and reflected by at least one of the objects, whether the at least one object is located outside of a distance measuring area within which a distance to the at least one object can be measured using the first mode.
