TL;DR: In this paper, a succession of first and second image frames from at least two different points of view is acquired, and image processing is performed on the first and the second frames, such that progressively different partial images of at least focussed and converged subject images in the second image frame are substituted for corresponding subject partial images in first image frames in repeating sequence on a corresponding image frame-by-image frame basis.

Abstract: Autostereoscopic imaging is achieved by acquiring succession of first and second image frames from at least two different points of view, and image processing the first and second image frames, such that progressively different partial images of at least focussed and converged subject images in the second image frames are substituted for corresponding subject partial images in the first image frames in repeating sequence on a corresponding image frame-by-image frame basis to create a succession of composite image frames. Two-dimensional display of the resulting succession of composite image frames is perceivable in three-dimensional illusion.
