ABSTRACT:
The method and apparatus for making a composite image of a scene a large-aperture lens to form an image of the scene on a photographic film through a lenticular screen or a barrier strip. The recorded image on film is digitized into a digital image and conveyed to a computer workstation for processing. Assuming the image area in the recorded image under each lenticule is digitized into an image zone composed of N pixel rows in the digital image. To correct the pseudoscopic effect, the order of each group of N pixel rows in each image zone is electronically reversed. Also, the entire digital image is electronically reversed to become a normal composite image. The image reversal process (for the entire image) can also be effected optically by forming the scene image through a plane mirror. The composite image in digital form can be used to produce 3D display, video and hard-copies by presenting the composite image behind a lenticular screen or a barrier strip. A similar method can be used to produce a composite image of a series of M scenes for making animation picture. In addition to the components described above, an aperture plate having an opening the width of which is substantially equal to 1/M of the taking lens aperture is moved to M different positions such that each of the M scenes is formed through a different section of the lens aperture.
