Abstract
Abstract A stereoscopic disk (50) for viewing stereo images in a binocular viewer includes a film disk with a plurality of stereo image pairs (54) disposed around the periphery of the film disk, sandwiched between a pair of disks of opaque material defining windows, in which the stereo images on the film disk are located. A method for making the stereoscopic disks includes the steps of making a master image (68) of the stereoscopic images arranged in a circular pattern, printing the master image onto photographic film, laminating the film with strips of opaque material (56,58) having windows for the images on the disk, and punching out the finished disk from the laminated assembly. A simple stereo viewer employs the film disks without the laminations.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A stereoscopic disk, comprising: a. a disk of photographic film bearing a plurality of stereoscopic image pairs arranged around the circumference of the disk; and b. first and second disks of opaque material defining a plurality of windows around the periphery of said opaque disks, said disks of photographic film being laminated between said first and second disks of opaque material with said image pairs located in said windows.
Claim 2
Dependent Claim
13 words
The stereoscopic disk claimed in claim 1, wherein said opaque material is paper.
Claim 3
Dependent Claim
20 words
The stereoscopic disk claimed in claim 1 or 2, wherein the stereo pairs are spaced diametrically apart by between 55-58mm.
Claim 4
Dependent Claim
20 words
The stereoscopic disk claimed in any of claims 1 to 3, having seven pairs of images of 10.5 x 11.7mm.
Claim 5
Independent Claim
70 words
A method of making a stereoscopic disk, comprising the steps of: a. providing a master stereoscopic image including a plurality of stereoscopic image pairs arranged in a circle; b. printing the master stereoscopic image onto a strip of photographic film in a photographic printer; c. developing the stereoscopic image in the photographic film; and d. forming a disk containing the print of the stereoscopic images out of the photographic film.
Claim 6
Dependent Claim
67 words
The method claimed in claim 5, wherein said step of printing the master stereoscopic image further comprises the steps of: a. preparing a second generation master loop of film bearing a plurality of images of said master stereoscopic image, and b. printing said secondary master image onto said strip of photographic film while simultaneously advancing said strip of photographic film and circulating said second generation master loop.
Claim 7
Dependent Claim
80 words
The method claimed in claim 5 or 6 wherein said step of providing a master stereoscopic image, further comprises the steps of: a. recording a plurality of stereo image pairs on a photographic film; b. scanning the stereo image pairs in a film scanner to produce digital images; c. manipulating the digital images to compensate for subsequent printer distortion and to arrange the digital images in a circle; and d. generating the master stereoscopic image on a digital film writer.
Claim 8
Dependent Claim
55 words
The method claimed in claim 5 or 6, wherein said step of providing a master stereoscopic image comprises the steps of: a. generating a plurality of digital stereo image pairs; b. manipulating the digital stereo image pairs in a digital image processing computer; and c. generating the master stereoscopic image on a digital film writer.
Claim 9
Dependent Claim
42 words
The method claimed in claim 5 to 8 further comprising the step of laminating the photographic transparency material between a pair of disks of opaque material defining windows around the periphery of the disks, with the stereo images located in said windows.
Claim 10
Dependent Claim
59 words
A stereoscopic device, comprising: a. a film disk having a plurality of stereo image pairs arranged around the periphery of the film disk; b. a retainer for holding the film disk; and c. a binocular viewer mated to the retainer for rotatably locating successive stereo image pairs on said disk in a field of view of said binocular viewer.
