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.

摘要:
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.
