ABSTRACT:
In processing a plurality of original images from different viewpoints through a lenticular sheet having a plurality of lenticular lenses to form a plurality of corresponding linear picture elements that are to be projected on a picture element recording or display medium, the following steps are taken: launching the beams of light from the respective original images into one or a corresponding number of projection lenses; separating the transmitted beams for the respective original images by means of a mirror optical assembly consisting of mirror units each composed of at least two mirrors for each original image; adjusting the optical pathlengths of the beams to the picture element recording or display medium by means of the mirror assembly; adjusting the key subject matter in the mirror assembly so that it will register among the projected views of all original images; allowing the beams to be incident on lenticular lenses at predetermined projecting angles; and imaging those beams as linear picture elements on the picture element recording or display medium so that the plurality of original images from different viewpoints are simultaneously projected on the picture element recording or display medium, either simultaneously or in at least two steps, to produce sharp images with high efficiency.
