Abstract
Abstract A single camera autostereoscopic recording system includes a single image recorder having a single optical path moved along the scanning path substantially continuously for a plurality of scanning cycles. A path defining structure includes the ability to adjust the convergent point as well as the extent of travel along the scanning path or disparity of the images. The convergent point of the scanning path can be manually or automatically adjusted using a range finder. A unique driver structure provides scanning motion with reduced reactional forces. The degree of motion of the recorded images is used to adjust the amount of travel along the scanning path. Synchronization between the driver and the recorder is bi-directional for double exposures. The recorded image is adjusted in recording or in display as a function of the position in the scanning path.
