US4575207A — Three-dimensional effect representation, and came…

Claim 1

Independent Claim 205 words

Apparatus for providing three-dimensional effect transparencies, said apparatus comprising: a camera including mounting means for retaining a photosensitive assembly at a predetermined location, and a movable lens, movable support means disposed in front of said lens for supporting an object whose image is to be taken; and said photosensitive assembly which comprises a layer of photosensitive material, a generally planar line screen having regularly spaced blocking portions spaced by transparent portions, and a transparent spacer disposed between said material and said line screen; said camera having a central axis with which said photosensitive assembly is aligned, said lens and said support means each having respective guide means so that they are movable along respective paths which are substantially linear, parallel to one another and are substantially normal to said central axis, whereby a three-dimensional effect transparency can be produced by placing said object at a number of spaced object positions and for each position aligning said lens with said object and the intersection of said central axis with said assembly and opening said lens to expose a segment of said photosensitive material, the number of object positions being sufficient to substantially completely fill all photosensitive material segments beneath the blocking portions of said line screen.

Claim 2

Dependent Claim 205 words

Apparatus for providing three-dimensional effect transparencies, said apparatus comprising: a camera including mounting means for retaining a photosensitive assembly at a predetermined location, and a movable lens, movable support means disposed in front of said lens for supporting an object whose image is to be taken; and said photosensitive assembly which comprises a layer of photosensitive material, a generally planar line screen having regularly spaced blocking portions spaced by transparent portions, and a transparent spacer disposed between said material and said line screen; said camera having a central axis with which said photosensitive assembly is aligned, said lens and said support means each having respective guide means so that they are movable along respective paths which are substantially linear, parallel to one another and are substantially normal to said central axis, whereby a three-dimensional effect transparency can be produced by placing said object at a number of spaced object positions and for each position aligning said lens with said object and the intersection of said central axis with said assembly and opening said lens to expose a segment of said photosensitive material, the number of object positions being sufficient to substantially completely fill all photosensitive material segments beneath the blocking portions of said line screen.

Claim 6

Dependent Claim 40 words

Apparatus as set forth in claim 4 wherein said mirror is aligned with said object and said lens and is disposed above said photosensitive assembly, said mirror having a reflective surface disposed at substantially a 45° with respect to vertical.

Claim 7

Dependent Claim 184 words

A transparency assembly for providing a three-dimensional visual effect of an object, the images carried by said assembly resulting from exposures taken by a camera having a central axis, means for holding photosensitive material with respect to said axis and a lens movable along a lens path extending transversely of said axis with said lens having spaced exposure locations on said lens path, one exposure being taken at each exposure location, said object being movable along an object path also extending transversely of said central axis, said object having a position on said object path corresponding to each of said exposure locations, said transparency assembly comprising: a line screen having blocking portions spaced by transparent portions; a transparency recording said images; and a transparency spacer disposed between said screen and said transparency; said transparency comprising a plurality of image segments extending parallel to said transparent portions and corresponding in location and number thereto, each image segment being completely exposed and comprising a single exposure image strip corresponding to each exposure location, adjacent signle exposure image strips being spaced by a double exposure image strip.

Claim 8

Dependent Claim 184 words

A transparency assembly for providing a three-dimensional visual effect of an object, the images carried by said assembly resulting from exposures taken by a camera having a central axis, means for holding photosensitive material with respect to said axis and a lens movable along a lens path extending transversely of said axis with said lens having spaced exposure locations on said lens path, one exposure being taken at each exposure location, said object being movable along an object path also extending transversely of said central axis, said object having a position on said object path corresponding to each of said exposure locations, said transparency assembly comprising: a line screen having blocking portions spaced by transparent portions; a transparency recording said images; and a transparency spacer disposed between said screen and said transparency; said transparency comprising a plurality of image segments extending parallel to said transparent portions and corresponding in location and number thereto, each image segment being completely exposed and comprising a single exposure image strip corresponding to each exposure location, adjacent signle exposure image strips being spaced by a double exposure image strip.

Claim 9

Dependent Claim 22 words

A transparency assembly as set forth in claim 6 further comprising frame means for maintaining said screen, transparency and spacer in registration.

Claim 10

Dependent Claim 16 words

A transparency assembly as set forth in claim 6 further including means for backlighting said transparency.

Claim 11

Dependent Claim 19 words

A transparency assembly as set forth in claim 6 wherein said transparency is the development of said photosensitive material.

Claim 12

Dependent Claim 33 words

A transparency assembly as set forth in claim 6 wherein said lens path and said object path are substantially linear, are parallel to one another and are substantially normal to said central axis.

Claim 13

Independent Claim 181 words

A method of producing a three-dimensional effect transparency using a camera having a movable lens, said transparency resulting from the developement of photosensitive material which is part of an assembly comprising a line screen having blocking portions spaced by transparent portions with a transparent spacer disposed between said material and said line screen, said camera having a central axis with which said assembly is aligned, and said lens being movable along a path extending transversely of said central axis, said method comprising: identifying spaced object locations along an object path which extends transversely of said central axis; placing the object the image of which is to be recorded at one of said locations; disposing said lens at a lens location corresponding to the object location; opening the lens to expose strips of said material; and repeating the steps of placing, disposing and opening until the object has been photographed at all said object locations, said object locations being identified so that the resulting transparency includes completely exposed image segments comprising single exposure image strips spaced by a double exposure image strip.

Claim 14

Independent Claim 181 words

A method of producing a three-dimensional effect transparency using a camera having a movable lens, said transparency resulting from the developement of photosensitive material which is part of an assembly comprising a line screen having blocking portions spaced by transparent portions with a transparent spacer disposed between said material and said line screen, said camera having a central axis with which said assembly is aligned, and said lens being movable along a path extending transversely of said central axis, said method comprising: identifying spaced object locations along an object path which extends transversely of said central axis; placing the object the image of which is to be recorded at one of said locations; disposing said lens at a lens location corresponding to the object location; opening the lens to expose strips of said material; and repeating the steps of placing, disposing and opening until the object has been photographed at all said object locations, said object locations being identified so that the resulting transparency includes completely exposed image segments comprising single exposure image strips spaced by a double exposure image strip.
