Abstract
Abstract A film video player for sensing photographic images having a given resolution to produce a standard video signal having a lower resolution, includes a zoom lens for selectively varying the magnification of the film image with respect to the image sensor and means for selectively translating the film image vertically and horizontally with respect to the image sensor, whereby the available resolution of the film image is more effectively utilized by the film video player.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
In a film video player for sensing photographic images having a given resolution to produce a standard video signal having a lower resolution, the improvement comprising (a) zoom means for selectively varying the magnification of said film image; (b) scan means for selectively translating said film image vertically and horizontally whereby the resolution of the film image is available to be utilized by said video player; and (c) means for selectively rotating said film image with respect to said video frames.
Claim 2
Dependent Claim
81 words
In a film video player for sensing photographic images having a given resolution to produce a standard video signal having a lower resolution, the improvement comprising (a) zoom means for selectively varying the magnification of said film image; (b) scan means for selectively translating said film image vertically and horizontally whereby the resolution of the film image is available to be utilized by said video player; and (c) means for selectively rotating said film image with respect to said video frames.
Claim 3
Dependent Claim
50 words
The invention claimed in claim 1, wherein said zoom means has a range of magnification between a lower magnification wherein the film frame image just substantially fills the video frame and a higher magnification wherein the resolution of the magnified film image is substantially equal to the standard television resolution.
Claim 4
Dependent Claim
51 words
The invention claimed in claim 1, wherein said video player includes a solid state imaging sensing array, wherein said zoom means comprises a movable zoom lens element, and wherein said scan means comprises means for displacing said solid state image sensing array vertically and horizontally with respect to said zoom lens.
Claim 5
Dependent Claim
69 words
The invention claimed in claim 1, wherein said video player includes a solid state image sensing array, said zoom means comprises a zoom lens and a servo motor coupled to said zoom lens, and said means for translating said image comprises an X-Y translation stage and a pair of servo motors coupled to said translation stage, said solid state image sensing array being carried by said X-Y translation stage.
Claim 6
Dependent Claim
21 words
The invention claimed in claim 1, further comprising a hand-held control unit, including operator controls for said zoom and scan means.
Claim 7
Dependent Claim
34 words
The invention claimed in claim 4, wherein said image rotating means comprises a rotating stage and a servo motor connected to said rotating stage, said X-Y translating stage being carried by said rotating stage.
