Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A method of producing a composite hardcopy comprising: digitizing and storing a plurality of generated images captured on frames; determining a common point to said plurality of frames; creating multiple images from off-axis perspective projections using said common point; storing said images; splitting each image into a plurality of strips; interleaving said plurality of strips to form a composite of interleaved strips such that when viewed by a person a three dimensional image is formed in the mind of said person; performing an unsharp masking technique on said composite of interleaved strips to produce a sharper image composite; printing said sharper image composite using a hard copy output device; and laminating said sharper image composite onto a lenticular surface.
Claim 2
Independent Claim
119 words
A method of producing a composite hardcopy comprising: digitizing and storing a plurality of generated images captured on frames; determining a common point to said plurality of frames; creating multiple images from off-axis perspective projections using said common point; storing said images; splitting each image into a plurality of strips; interleaving said plurality of strips to form a composite of interleaved strips such that when viewed by a person a three dimensional image is formed in the mind of said person; performing an unsharp masking technique on said composite of interleaved strips to produce a sharper image composite; printing said sharper image composite using a hard copy output device; and laminating said sharper image composite onto a lenticular surface.
Claim 3
Independent Claim
116 words
A method of producing a composite hardcopy to be implemented using a computer comprising: digitizing and storing a plurality of generated images captured on frames; determining a common point to said plurality of frames; creating multiple images from off-axis perspective projections using said common point; storing said images; splitting each image into a plurality of strips; interleaving said plurality of strips to form a composite of interleaved strips such that when viewed by a person a three dimensional image is formed in the mind of said person; performing an unsharp masking technique on said composite of interleaved strips to produce a sharper composite image; and printing said sharper composite image using a hard copy output device.
Claim 4
Independent Claim
116 words
A method of producing a composite hardcopy to be implemented using a computer comprising: digitizing and storing a plurality of generated images captured on frames; determining a common point to said plurality of frames; creating multiple images from off-axis perspective projections using said common point; storing said images; splitting each image into a plurality of strips; interleaving said plurality of strips to form a composite of interleaved strips such that when viewed by a person a three dimensional image is formed in the mind of said person; performing an unsharp masking technique on said composite of interleaved strips to produce a sharper composite image; and printing said sharper composite image using a hard copy output device.
Claim 5
Independent Claim
145 words
A method of producing a high resolution hardcopy image on a lenticular surface comprising: providing a plurality of images; splitting each image into a plurality of strips; interleaving said plurality of strips to form a composite of interleaved strips such that when viewed by a person a three dimensional image is formed in the mind of said person; and performing an unsharp masking technique on said composite of interleaved strips; wherein said unsharp masking technique is implemented by the equation h=(1-a)×i+(a×b) where "i" is a predetermined intensity value on a first waveform representing an original image, "b" is an intensity value corresponding to said "i" on a second waveform representing a blurred image of said original image, "a" is a blending factor, "h" is a resulting intensity value corresponding to said "i" and said "b" on a third waveform representing said image having shared edges.
Claim 6
Independent Claim
145 words
A method of producing a high resolution hardcopy image on a lenticular surface comprising: providing a plurality of images; splitting each image into a plurality of strips; interleaving said plurality of strips to form a composite of interleaved strips such that when viewed by a person a three dimensional image is formed in the mind of said person; and performing an unsharp masking technique on said composite of interleaved strips; wherein said unsharp masking technique is implemented by the equation h=(1-a)×i+(a×b) where "i" is a predetermined intensity value on a first waveform representing an original image, "b" is an intensity value corresponding to said "i" on a second waveform representing a blurred image of said original image, "a" is a blending factor, "h" is a resulting intensity value corresponding to said "i" and said "b" on a third waveform representing said image having shared edges.
Claim 7
Dependent Claim
27 words
The method of claim 3 wherein said unsharp masking technique comprises a blurring step that uses a filter kernel, wherein said filter kernel is one pixel high.
Claim 8
Dependent Claim
19 words
The method of claim 4 wherein a blurred kernel and an input kernel are derived from said filter kernel.
Claim 9
Dependent Claim
15 words
The method of claim 5 wherein said blurred kernel and said input kernel are normalized.
Claim 10
Dependent Claim
9 words
The method of claim 3 wherein "a" is negative.
Claim 11
Dependent Claim
10 words
The method of claim 7 wherein "a" is approximately -0.2.
Claim 12
Dependent Claim
16 words
The method of claim 3 wherein each image has a different perspective from every other image.
