Abstract

Abstract A 3D camera for acquiring and recording a plurality of 2D images at different viewing angles without relocating the camera wherein a large-aperture taking lens is used for image forming and an aperture controlling means is used to select the section of the lens' aperture through which light rays are transmitted to form a 2D image at one viewing angle at a time. The 3D camera can also have a mirror assembly to direct light rays traversing different sections of the lens' aperture to form 2D images on different image planes.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 137 words
A 3D camera for acquiring and recording a plurality of 2D images of a single scene at different viewing angles without relocating said camera, said camera comprising: a taking lens; aperture controlling means for partitioning the aperture of said lens into a plurality of horizontally spaced sections for permitting light rays to transmit through each of said aperture sections to provide a 2D image at a different viewing angle; a plurality of mirror sets mounted behind said taking lens in registry with a plurality of said aperture sections for directing light rays transmitted through respective aperture sections to provide a plurality of 2D images taking at different viewing angles; image recording means for recording 2D images taken by said taking lens; and a shutter for controlling transmission of light rays through said sections of said lens aperture.
Claim 2
Dependent Claim 137 words
A 3D camera for acquiring and recording a plurality of 2D images of a single scene at different viewing angles without relocating said camera, said camera comprising: a taking lens; aperture controlling means for partitioning the aperture of said lens into a plurality of horizontally spaced sections for permitting light rays to transmit through each of said aperture sections to provide a 2D image at a different viewing angle; a plurality of mirror sets mounted behind said taking lens in registry with a plurality of said aperture sections for directing light rays transmitted through respective aperture sections to provide a plurality of 2D images taking at different viewing angles; image recording means for recording 2D images taken by said taking lens; and a shutter for controlling transmission of light rays through said sections of said lens aperture.
Claim 3
Dependent Claim 36 words
The 3D camera according to claim 1 wherein said aperture controlling means comprises a fixedly mounted opaque plate having a plurality of horizontally spaced openings positioned in registry with said sections of said lens aperture respectively.
Claim 4
Dependent Claim 15 words
The 3D camera according to claim 1 wherein said image recording means comprises photographic film.
Claim 5
Dependent Claim 17 words
The 3D camera according to claim 1 wherein said image recording means comprises an electronic imaging device.
Claim 6
Dependent Claim 21 words
The 3D camera according to claim 4 further comprising image storing means for storing images conveyed from said electronic imaging device.
Claim 7
Dependent Claim 18 words
The 3D camera according to claim 2 wherein the spacing between said openings are adjustable for parallax control.
Claim 8
Dependent Claim 172 words
A 3D camera for acquiring and recording a piurality of 2D images of a single scene at different viewing angles without relocating said camera, said camera comprising: a taking lens with the aperture of said lens being partitioned into a plurality of horizontally aligned sections through which light rays are transmitted to provide a plurality of 2D images at different viewing angles; image recording means for recording 2D images formed by said taking lens; a fixedly mounted window plate having an opening positioned in registry with a plurality of said sections of said lens aperture; a rotary disk having a plurality of openings; means for rotating said rotary disk to position one of said disk openings in registry with one of said sections of said lens aperture at a time so as to select said sections one at a time and to thereby eliminate unselected sections of said lens aperture from being used to provide images; and a shutter for controlling transmission of light rays through said sections of said lens aperture.
Claim 9
Dependent Claim 172 words
A 3D camera for acquiring and recording a piurality of 2D images of a single scene at different viewing angles without relocating said camera, said camera comprising: a taking lens with the aperture of said lens being partitioned into a plurality of horizontally aligned sections through which light rays are transmitted to provide a plurality of 2D images at different viewing angles; image recording means for recording 2D images formed by said taking lens; a fixedly mounted window plate having an opening positioned in registry with a plurality of said sections of said lens aperture; a rotary disk having a plurality of openings; means for rotating said rotary disk to position one of said disk openings in registry with one of said sections of said lens aperture at a time so as to select said sections one at a time and to thereby eliminate unselected sections of said lens aperture from being used to provide images; and a shutter for controlling transmission of light rays through said sections of said lens aperture.
