The improved method and apparatus for recording a stereoscopic image read a plurality of original images photoelectrically, split each original image into linear images of a desired pitch, perform any necessary image processing operations such as arranging the linear images in the recording order, and record the linear images by scan exposure on a lenticular light-sensitive material having a lenticular sheet and a recording layer. The method and apparatus permit the lenticular light-sensitive material to be scan exposed from the rear side and they also enable the linear images to be recorded with increased line width and a stereoscopic image to be formed with satisfactory registration between the principal objects of the original images. The improved lenticular light-sensitive material has an anti-halation layer provided between the lenticular sheet and the recording layer, thus permitting scan exposure to be effected from the rear side. According to the present invention, stereoscopic images of high quality that have no perceivable unnaturalness such as flickers can be recorded with great ease and at any desired magnification.

Method and apparatus for recording stereoscopic images and lenticular

The improved method and apparatus for recording a stereoscopic image calculate the linear image recording positions for each lenticular lens in connection with all of the linear images of the nth original image in such a way that all of the linear images of the nth original image that are to be recorded in association with the respective lenticular lenses will fall within the same area at the intended viewing position, and record the linear images by an image forming means on the basis of the results of said calculation. Therefore, according to the present invention, stereoscopic images of high quality can be recorded using the lenticular sheet without causing any serious defects such as multiple image or image flickering.

Method and apparatus for recording stereoscopic images

In the improved method for projection a stereoscopic image, an additional lenticular sheet that has an appropriate level difference and a different pitch of lenticular lenses than a lenticular recording material such as a lenticular light-sensitive material is either placed directly on top of said lenticular recording material or inserted above and in the vicinity of said lenticular recording material, with said additional lenticular sheet being preferably moved either in one direction or reciprocally in a direction generally perpendicular to its own generatrix. This method can be implemented with the improved apparatus for printing a stereoscopic photograph. Using the improved method and apparatus, the development of moire can be suppressed and, at the same time, the line width of linear image elements to be recorded can be easily expanded.

Method of projecting stereoscopic image and apparatus for printing

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.
