ABSTRACT:
Apparatus for recording a sequence of frames through a single lens system along different optical axes which exit the lens system along a common axis, and focus at a recording station, and which converge at a predetermined location in a scene to be recorded, comprises a recording station for film, or a photoelectronic scanner for video, a recording control providing for sequentially recording scenes focused at the recording station, and a lens system having a field of view encompassing scenes to be recorded and defining an optical path along which light rays pass from a scene and exit the lens system on a common axis to the recording station. A light shifting device is arranged to shift the optical path cyclically within the lens system between at least two different non-parallel axes which intersect at a predetermined location in a scene viewed by the lens system. Focus control provides for dynamically changing the intersection location of the axes of the different optical paths as the recording of scenes proceeds. The light shifting device may include a light refracting member or an iris piece which is shifted between different postions relative to the lens system axis in cyclic fashion synchronized to the recording control.
