Abstract
Abstract Displaying a two-dimensional photographic picture or portrait as if it is a three-dimensional one consisting of a front pattern, a back pattern and a photographic picture such as a photograph, a picture, printed matter or a photographic portrait by projecting the same on a screen such as a cinema screen television, or the like, wherein the front pattern and said back pattern are optically spaced from each other on a photographic picture or said screen to form a projected optical illusion image of said end area.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
191 words
A system for displaying a two-dimensional picture in a manner to produce the illusion that the picture has three dimensions comprising: first surface means having a two-dimensional picture displayed thereon, means defining first and second, front and rear, striped patterns extending outwardly from at least one edge of said picture and adjacent thereto with said patterns overlapped in spaced planes, the rear second striped pattern being viewed through the gaps between the stripes of the first front pattern, and the relationship between the horizontally measured pitch of said first front and second rear patterns is given by the formula M2 (M1+d X M1) X n, wherein; M2 is the measured horizontal pitch of the optical stripes of the second rear pattern, M1 is measured horizontal pitch of the optical stripes of the first front pattern, d is a numerical value between 10 6 and 0.4, and n is a positive integer of from 1 to 10, whereby; an optical interference between the striped patterns gives the illusion that the area adjacent to at least said one edge of said picture is in a plane differing from the plane of the picture.
Claim 2
Independent Claim
191 words
A system for displaying a two-dimensional picture in a manner to produce the illusion that the picture has three dimensions comprising: first surface means having a two-dimensional picture displayed thereon, means defining first and second, front and rear, striped patterns extending outwardly from at least one edge of said picture and adjacent thereto with said patterns overlapped in spaced planes, the rear second striped pattern being viewed through the gaps between the stripes of the first front pattern, and the relationship between the horizontally measured pitch of said first front and second rear patterns is given by the formula M2 (M1+d X M1) X n, wherein; M2 is the measured horizontal pitch of the optical stripes of the second rear pattern, M1 is measured horizontal pitch of the optical stripes of the first front pattern, d is a numerical value between 10 6 and 0.4, and n is a positive integer of from 1 to 10, whereby; an optical interference between the striped patterns gives the illusion that the area adjacent to at least said one edge of said picture is in a plane differing from the plane of the picture.
Claim 3
Dependent Claim
34 words
The system as claimed in claim 1, wherein the means for displaying said two dimensional picture comprises a television receiver and said first surface means comprises an image receiving tube of said television receiver.
Claim 4
Dependent Claim
49 words
The system as claimed in claim 1, wherein said means defining front and rear, first and second, striped patterns are the surfaces respectively of a transparent material plate positioned adjacent to the border of said displayed picture, said transparent plate carrying wavelike stripes at least on its front surface.
Claim 5
Dependent Claim
52 words
The system as claimed in claim 1, wherein the angle between a vertical line and the stripes of said first front pattern ranges between 10* and 45* and the angle between a vertical line and the stripes of said second rear pattern is greater than the above-mentioned angle in the same direction.
Claim 6
Dependent Claim
24 words
The system as claimed in claim 2, in which the lateral end portions of said image receiving tube comprises said second rear striped pattern.
Claim 7
Dependent Claim
38 words
The system as claimed in claim 2, wherein the side end portions of the surfaces of the image-receiving tube screen is such that it fades to nontransparent color in the direction toward the outer edge of the screen.
Claim 8
Dependent Claim
43 words
The system as claimed in claim 2, where the first front striped pattern comprises a transparent plate positioned in front of said image receiving tube, said transparent plate carrying wavelike stripes, and said second, rear striped pattern comprises a rear plate carrying stripes.
Claim 9
Dependent Claim
31 words
The system as claimed in claim 7, wherein said first front transparent plate is devoid of wavelike stripes on that portion which corresponds to the surface of said image receiving tube.
Claim 10
Dependent Claim
26 words
The system as claimed in claim 7, wherein said wavelike striped pattern on the first front transparent plate is replaced by a blindlike or netlike pattern.
Claim 11
Dependent Claim
54 words
The system as claimed in claim 1, wherein the means for displaying said two-dimensional picture upon said first surface is a projector, said first surface is a screen, said projector projects its image upon said screen from the direction opposite that of the viewer and said first front striped pattern adopts a wavelike form.
Claim 12
Dependent Claim
16 words
The system as claimed in claim 3, wherein said wavelike pattern comprises a painted color pattern.
Claim 13
Dependent Claim
67 words
The system as claimed in claim 1, further including means for phasing the edge portions of the picture carried by said first surface means into darkness in a direction toward the outside of said first surface means, said phasing means including a light projected on the surface means area adjacent said edge and a suitable filter positioned between said projecting light source and said first surface means.
Claim 14
Dependent Claim
42 words
The system as claimed in claim 1, wherein said first surface means is a screen and the means for displaying said two-dimensional picture upon the screen is a projector which projects that picture from the side of the screen facing the viewer.
Claim 15
Dependent Claim
35 words
The system as claimed in claim 13, wherein the edge portions of said screen fade into darkness by painting a color on the screen which darkens in a direction towards the outside of said screen.
Claim 16
Dependent Claim
48 words
The system as claimed in claim 13, wherein said first front pattern is a blindlike or netlike pattern set in the same plane as said screen and said second rear striped pattern is carried by a rearwardly offset plate on the side of the screen opposite the viewers.
Claim 17
Dependent Claim
23 words
The system as claimed in claim 1 further including mirrors positioned between and generally perpendicular to first front and second rear striped patterns.
Claim 18
Dependent Claim
54 words
The system as claimed in claim 2, wherein the first front striped pattern comprises a transparent plate positioned in front of said image-receiving tube, said transparent plate carries a color painted striped pattern on a surface thereof overlying said image receiving tube and said second, rear striped pattern comprises a rear plate carrying stripes.
Claim 19
Dependent Claim
44 words
The system as claimed in claim 15, wherein; the darker color of said blindlike or netlike front pattern fades into a lighter color in a direction toward the line of intersection between said screen and the circumferential lateral end areas of said front pattern.
Claim 20
Dependent Claim
52 words
The system as claimed in claim 2, wherein the angle between a vertical line and the stripes of said first front pattern ranges between 10* and 45* and the angle between a vertical line and the stripes of said second rear pattern is greater than the above-mentioned angle in the same direction.
Claim 21
Dependent Claim
53 words
The system as claimed in claim 7, wherein the angle between a vertical line and the stripes of said first front pattern ranges between 10* and 45* and the angle between a vertical line and the stripes of said second rear pattern is greater than the above mentioned angles in the same direction.
