Abstract
Mobile refractive optical members are placed in a device between the film and stereoscopic direct viewing windows. A drive is provided for driving the film strip bearing stereoscopic images and the mobile refractive optical members at a uniformly constant speed and in synchronism across the fields of view of the viewing windows to provide a fixed image in each window despite the motion of the film; the film strip has a sound track which may be reproduced by conventional reproduction equipment since the film strip is driven at a constant speed.
