Abstract
Abstract A method of photographing and reproducing three-dimensional images which is characterized by photographing, developing or transmitting two or more images of the object as viewed from different directions with such magnifying powers as being different in vertical direction and lateral direction, using a lens system having such focal distances as being different in vertical direction and lateral direction.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
101 words
A method for photographing and reproducing three-dimensional images, which comprises photographing a plurality of images of an object from different directions and with magnifying powers different in the vertical direction from the lateral direction by using a plurality of lens systems each having a focal distance different in the vertical direction and lateral direction, developing the images, and projecting the plurality of images of the object obtained upon substantially the entire area of a direction selective screen for reproducing a three-dimensional image using a plurality of lens systems each having essentially the same structure as that used for photographing the images.
Claim 2
Independent Claim
101 words
A method for photographing and reproducing three-dimensional images, which comprises photographing a plurality of images of an object from different directions and with magnifying powers different in the vertical direction from the lateral direction by using a plurality of lens systems each having a focal distance different in the vertical direction and lateral direction, developing the images, and projecting the plurality of images of the object obtained upon substantially the entire area of a direction selective screen for reproducing a three-dimensional image using a plurality of lens systems each having essentially the same structure as that used for photographing the images.
Claim 3
Dependent Claim
41 words
The method as in claim 1, wherein photographing and projecting of the images is accomplished with a plurality of lens systems having cylindrical lenses vertically arranged and a cylindrical lens horizontally arranged in optical alignment with the vertically arranged cylindrical lenses.
Claim 4
Dependent Claim
46 words
A method as in claim 1, wherein the lens systems are assembled on the screen of a picture tube during the photographing step and the lens systems are assembled with a fluorescent surface of a cathode ray tube of a three-dimensional television during the reproducing step.
Claim 5
Independent Claim
134 words
An apparatus for producing images capable of being viewed three-dimensionally, comprising sensory means having a sensing portion for sensing the images, a plurality of first lens means located to direct light to the sensing portion of said sensory means and each having a larger focal length in one direction transverse to the light being directed than in a second direction transverse to the light and to the one direction, said first lens means being mutually adjacent to each other, second lens means in the path of light passing through the plurality of first lens means and having a larger focal length in the second direction than the first direction for varying the images produced by said first lens means, said first lens means being positioned between said second lens means and said sensing means.
Claim 6
Independent Claim
134 words
An apparatus for producing images capable of being viewed three-dimensionally, comprising sensory means having a sensing portion for sensing the images, a plurality of first lens means located to direct light to the sensing portion of said sensory means and each having a larger focal length in one direction transverse to the light being directed than in a second direction transverse to the light and to the one direction, said first lens means being mutually adjacent to each other, second lens means in the path of light passing through the plurality of first lens means and having a larger focal length in the second direction than the first direction for varying the images produced by said first lens means, said first lens means being positioned between said second lens means and said sensing means.
Claim 7
Dependent Claim
41 words
An apparatus as in claim 4, wherein said first lens means have larger focal lengths in the vertical direction than the horizontal direction and said second lens means has a larger focal length in the horizontal direction than the vertical direction.
Claim 8
Dependent Claim
37 words
An apparatus as in claim 4, wherein said first lens means each include a cylindrical component having in an axis along the one direction and said second lens means has a cylindrical component along the second direction.
Claim 9
Dependent Claim
21 words
An apparatus as in claim 4, wherein said first lens means each produce separate images for light coming from different directions.
Claim 10
Dependent Claim
30 words
An apparatus as in claim 4, wherein said sensory means includes a photographic film and wherein housing means hold said lens means and said sensory means relative to each other.
Claim 11
Dependent Claim
38 words
An apparatus as in claim 4, wherein said sensing means includes a television picture-taking tube having a front face, and wherein said first lens means and said second lens means are mounted in front of said front face.
Claim 12
Independent Claim
129 words
An apparatus for viewing images three-dimensionally, comprising image forming means for forming a plurality of adjacent images indicative of information seen from different directions, a plurality of first lens means located in the path of light from said image forming means and each having a larger focal length in one direction transverse to the path of light than a second direction transverse to the path of light and to the one direction, second lens means in the path of the light passing through the plurality of first means and having a longer focal length in the second direction than in the first direction for varying the images Passed by said first lens means, said first lens means being positioned between said second lens means and said image forming means.
Claim 13
Independent Claim
129 words
An apparatus for viewing images three-dimensionally, comprising image forming means for forming a plurality of adjacent images indicative of information seen from different directions, a plurality of first lens means located in the path of light from said image forming means and each having a larger focal length in one direction transverse to the path of light than a second direction transverse to the path of light and to the one direction, second lens means in the path of the light passing through the plurality of first means and having a longer focal length in the second direction than in the first direction for varying the images Passed by said first lens means, said first lens means being positioned between said second lens means and said image forming means.
Claim 14
Dependent Claim
30 words
An apparatus as in claim 10, further comprising a direction selective screen, and wherein each of said first lens means projects one of said images over substantially the entire screen.
Claim 15
Dependent Claim
33 words
An apparatus as in claim 10, wherein said first lens means each have a cylindrical component in the one direction and said second lens means have a cylindrical component in the second direction.
Claim 16
Dependent Claim
43 words
An apparatus as in claim 10, wherein said image forming means includes a cathode ray tube producing a plurality of images and having a front face, and wherein the first lens means and said second lens means are mounted on the front face.
