ABSTRACT:
Detailed depth information in a three dimensional scene is recorded by a camera with a single lens system (100). In one embodiment, a lens (100) is movably attached to a camera housing (302) such that a motor (304) can move the lens (100) in the direction of the central axis of the lens (100). A two dimensional array (300) of photo-sensors is mounted in the camera along the central axis of the lens (100). As the lens system (100) is traversed along the central axis, objects at various distances (106) in front of the lens system (100) pass in and out of focus on the array (300) of photo-sensors. For a lens system (100) with a known focal length, the distance (108) between the lens system (100) and the array (300) when an object (102) comes into focus on the array (300) indicates the distance (106) between the lens system (100) and the object (102). The distance (106) from the lens system (100) to a plurality of points in a scene is calculated by determining the distance (108) between the lens system (100) and the array (300) when each of the points comes into focus on the array (300). Information related to the distance (106) from the lens system (100) to the plurality of points is recorded.
