Claim 1
Independent Claim
335 words
A photographic camera for three dimension photography comprising: a housing having an opening to the interior for light rays; means for immovably locating photosensitive material in communication with the interior of the housing at a location during a time for exposure; optical means in said housing for projecting light rays, which are received through said opening from a scene to be photographed, along an optical path to said location, said path having a first position therealong extending transversely to the direction of the path from a first side to a second side of the path, the optical means comprising a lenticular screen extending across said path at a second position farther along said path from the first position and having, on one side, a plurality of elongated lenticular elements of width P which face in the direction from which the light rays are being projected and having an opposite side facing and positioned for contact with the surface of such located photosensitive material, the optical means being characterized in that it changes, by a predetermined distance Y, on such surface of the photosensitive material, the position of light rays which come from a substantially common point on such scene and which extend along said first and second sides of said path; means for blocking the received light rays at said first position; an aperture movable transversely across said path at said first position, from said first side to said second side, for exposing said light rays sequentially to the photosensitive material moving across said screen in a direction normal to the elongation of said lenticular elements; and means for so moving said aperture for a predetermined time for exposure while simultaneously and synchronously moving said screen, substantially throughout said predetermined time for exposure, in substantially the same direction as the light rays sequentially expose said photosensitive material and over a distance substantially equal to the sum of P + Y to thereby expose a substantially continuous unreversed image of the scene on the photosensitive material.

A photographic camera for three dimension photography comprising: a housing having an opening to the interior for light rays; means for immovably locating photosensitive material in communication with the interior of the housing at a location during a time for exposure; optical means in said housing for projecting light rays, which are received through said opening from a scene to be photographed, along an optical path to said location, said path having a first position therealong extending transversely to the direction of the path from a first side to a second side of the path, the optical means comprising a lenticular screen extending across said path at a second position farther along said path from the first position and having, on one side, a plurality of elongated lenticular elements of width P which face in the direction from which the light rays are being projected and having an opposite side facing and positioned for contact with the surface of such located photosensitive material, the optical means being characterized in that it changes, by a predetermined distance Y, on such surface of the photosensitive material, the position of light rays which come from a substantially common point on such scene and which extend along said first and second sides of said path; means for blocking the received light rays at said first position; an aperture movable transversely across said path at said first position, from said first side to said second side, for exposing said light rays sequentially to the photosensitive material moving across said screen in a direction normal to the elongation of said lenticular elements; and means for so moving said aperture for a predetermined time for exposure while simultaneously and synchronously moving said screen, substantially throughout said predetermined time for exposure, in substantially the same direction as the light rays sequentially expose said photosensitive material and over a distance substantially equal to the sum of P + Y to thereby expose a substantially continuous unreversed image of the scene on the photosensitive material.
Claim 3
Dependent Claim
41 words
A photographic camera according to claim 1 wherein said means for focussing comprises at least one objective lens positioned on the opening side of the location for aperture movement and at least one further lens positioned on the other side thereof.
Claim 4
Dependent Claim
29 words
A photographic camera according to claim 2 comprising at least one mask adjacent said first position and aligned with said opening for defining an outer boundary for said path.
Claim 5
Dependent Claim
26 words
A photographic camera according to claim 3 wherein said lenses have a diameter which is substantially larger than the opening of said at least one mask.
Claim 6
Dependent Claim
23 words
A photographic camera according to claim 1 wherein said lenticular elements have a width in the range between 0.1 mm and 1 mm.
Claim 7
Dependent Claim
18 words
A photographic camera according to claim 1 wherein said blocking means comprises a shutter curtain containing said aperture.
Claim 8
Dependent Claim
32 words
A photographic camera according to claim 6 comprising a motor for driving said shutter and for causing said aperture to move from said first side to the second side of said path.
Claim 9
Dependent Claim
15 words
A photographic camera according to claim 7 comprising an additional motor for driving said screen.
Claim 10
Dependent Claim
24 words
A photographic camera according to claim 7 comprising electrical control means for driving the shutter motor and the screen motor substantially simultaneously and synchronously.
Claim 11
Dependent Claim
45 words
A photographic camera according to claim 1 wherein said means for locating comprises positioning such photosensitive material against said screen and means for applying a uniform pressure, over at least a portion of such photosensitive material, against said lenticular screen to maintain uniform contact therebetween.
