Method and apparatus for recording stereoscopic images and lenticular recording material used therefor
First Claim
1. An apparatus for recording stereoscopic images, which records a plurality of original images from different viewpoints on a lenticular recording material having recording material provided on the rear side of a lenticular sheet, comprising:
- image processing means which obtains image information on said plurality of original images, which forms linear images to be recorded for each of said original images, which determines positions in which the linear images are to be recorded on said recording material in accordance with conditions for recording the original images, such that a completed stereoscopic image will be correctly produced when viewed from a front side of said lenticular sheet, and which outputs linear image information;
image forming means that comprises;
means which issues a light beam modulated in accordance with the linear image information provided by said image processing means, and which deflects said light beam one-dimensionally in a fast scan direction which is parallel to a generatrix of said lenticular sheet; and
means which moves said lenticular recording material relative to the light beam deflected in said fast scan direction in a slow scan direction, the slow scan direction being generally perpendicular to said fast scan direction, said image forming means exposing the recording material of said lenticular recording material from the rear side with said light beam; and
means for determining positions for image recording on said lenticular recording material.

Abstract
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.

3. An apparatus for recording stereoscopic images, which records a plurality of original images from different viewpoints on a lenticular recording material having a recording material provided on the rear side of a lenticular sheet, comprising:
-
image processing means which obtains image information on said plurality of original images, which forms linear images to be recorded for each of said original images, which determines positions in which a sequence of the linear images are to be recorded on said recording material in accordance with conditions for recording the original images, such that a completed stereoscopic image will be correctly produced when viewed from a front side of said lenticular sheet, and which outputs linear image information; a display on which said linear images are represented in accordance with said linear image information delivered from said image processing means; and means for determining the positions for image recording on said lenticular recording material, wherein the image represented on said display is recorded on a rear surface of said lenticular recording material as a longitudinal direction of said linear images is brought into substantial registry with a direction of a generatrix of said lenticular sheet while the sequence of said linear images in a transverse direction is brought into correspondence with the pitch of lenticular lenses in said lenticular recording material. - View Dependent Claims (4)

5. An apparatus for recording stereoscopic images, with which linear images as produced from a plurality of original images from different viewpoints are recorded to produce a stereoscopic image on a lenticular recording material having a lenticular sheet and a recording layer, comprising:
-
image processing means which obtains image information on said plurality of original images, which splits each of said original images into linear images to be recorded, which determines positions in which said linear images are to be recorded on said recording layer, and which outputs image information; image forming means, comprising;
a light beam issuing unit for issuing a light beam modulated in accordance with the image information delivered from said image processing means; and
