A lens aperture of an autostereoscopic camera is moved in a parallax scannin g pattern through a plurality of disparity positions off set from the optical axis of the camera lens. Images of a scene being photograph ed, as viewed through the lens aperture in its various d isparity positions, are recorded for subsequent display in three-dimensional illusion when viewed with the unaided eye. The size of the lens aperture and the parallax scanning pattern are adjustable to suit conditions. The len s aperture may be defined as a through-hole in an opaque card or a planar array of cells switched between transparent and opaque states. I n addition to stereoscopic imaging, the moving lens aper ture principle of the present invention may be utilized in range-finding and came ra image stabilization applications. |
