Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
A digital printer for printing images in response to full-frame, two-dimensional digital image data input from an outside source, said digital printer comprising: a two dimensional backlight for producing full frame illumination in a single flash; a photoreceptor sensitive to light emanating from said backlight; a two-dimensional, transmissive light valve disposed between said backlight and said photoreceptor so that light from said backlight is transmitted through said light valve to produce a full-frame, two dimensional image on said photoreceptor in response to a single flash of the backlight, said full-frame, two dimensional -- image corresponding to a pattern formed on said light valve in response to said full-frame, two dimensional -- digital image data; an imaging system disposed between said light valve and said photoreceptor, such that said imaging system focuses said full-frame, two dimensional -- image onto said photoreceptor; and a driver coupled to said light valve, said backlight and said outside source, said driver coupling said full-frame, two dimensional digital image data from said outside source to said light valve and synchronizing said backlight with said light valve such that said backlight flash exposes said light valve after said pattern is set on said light valve in response to said full-frame, two dimensional digital image data.
Claim 2
Dependent Claim
208 words
A digital printer for printing images in response to full-frame, two-dimensional digital image data input from an outside source, said digital printer comprising: a two dimensional backlight for producing full frame illumination in a single flash; a photoreceptor sensitive to light emanating from said backlight; a two-dimensional, transmissive light valve disposed between said backlight and said photoreceptor so that light from said backlight is transmitted through said light valve to produce a full-frame, two dimensional image on said photoreceptor in response to a single flash of the backlight, said full-frame, two dimensional -- image corresponding to a pattern formed on said light valve in response to said full-frame, two dimensional -- digital image data; an imaging system disposed between said light valve and said photoreceptor, such that said imaging system focuses said full-frame, two dimensional -- image onto said photoreceptor; and a driver coupled to said light valve, said backlight and said outside source, said driver coupling said full-frame, two dimensional digital image data from said outside source to said light valve and synchronizing said backlight with said light valve such that said backlight flash exposes said light valve after said pattern is set on said light valve in response to said full-frame, two dimensional digital image data.
Claim 3
Dependent Claim
67 words
The digital printer as recited in claim 1 wherein said driver further comprises: a light valve driver coupled to said light valve to provide said digital image data; a backlight driver coupled to said backlight to control flash exposure; and a means for synchronizing said light valve driver and said backlight driver such that said backlight flash exposes only when said light valve has set said pattern.
Claim 4
Dependent Claim
16 words
The digital printer as recited in claim 1 wherein said imaging system comprises a lenslet array.
Claim 5
Dependent Claim
24 words
The digital printer as recited in claim 3 wherein said lenslet array comprises an array of spherical lenses surrounded by areas of opaque material.
Claim 6
Dependent Claim
21 words
The digital printer as recited in claim 3 wherein said lenslet array comprises an array of proximate lenses having edge-to-edge contact.
Claim 7
Dependent Claim
16 words
A digital printer as recited in claim 1 wherein said photoreceptor further comprises a moving belt.
Claim 8
Dependent Claim
33 words
A digital printer as recited in claim 6 wherein said backlight produces light for a period of time such that a blur of said image on said photoreceptor is within a predefined tolerance.
