Abstract
Abstract A device for recording image signals of photographic pictures, wherein the photographic pictures on a negative film are converted to electrical image signals by a video camera and recorded in a recording medium such as a magnetic disc. This device for recording image signals also produces a print on a print paper from the negative film. Light transmitted through the negative film is split into two images including an image falling on an image sensing surface of a video camera and another image for exposing a print paper.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A device for recording images of photographic pictures, comprising: a first optical system including: light source means for emitting light and for transmitting said light through a negative film embodying photographic pictures; means for producing electrical image signals including an image sensing surface; means for focusing said light transmitted through said negative film onto said image sensing surface; means for recording said electrical image signals output from said means for producing: light splitting means located between said negative film and said image sensing surface in a path of said light transmitted through said negative film, for splitting said light transmitted through said negative film into first and second images, said first image being focussed on said image sensing surface; and a second optical system including means for focussing said second image produced by said beam splitting means onto a print paper to expose said print paper.
Claim 2
Independent Claim
146 words
A device for recording images of photographic pictures, comprising: a first optical system including: light source means for emitting light and for transmitting said light through a negative film embodying photographic pictures; means for producing electrical image signals including an image sensing surface; means for focusing said light transmitted through said negative film onto said image sensing surface; means for recording said electrical image signals output from said means for producing: light splitting means located between said negative film and said image sensing surface in a path of said light transmitted through said negative film, for splitting said light transmitted through said negative film into first and second images, said first image being focussed on said image sensing surface; and a second optical system including means for focussing said second image produced by said beam splitting means onto a print paper to expose said print paper.
Claim 3
Dependent Claim
66 words
A device for recording image signals of photographic pictures as recited in claim 1, wherein said first optical system further includes variable prism means, located between said negative film and said image sensing surface and being rotatable through predetermined angles, for changing an orientation of said light transmitted through said negative film whereby said light has a single orientation when focussed on said image sensing surface.
Claim 4
Dependent Claim
26 words
A device for recording image signals of photographic pictures as recited in claim 2, wherein said means for producing electrical image signals is a video camera.
Claim 5
Dependent Claim
59 words
A device for recording image signals of photographic pictures as recited in claim 3, wherein said recording means includes: inversion circuit means for inverting a luminescence level of said electrical image signals produced by said means for producing, to provide inverted electrical image signals; and correction circuit means for correcting a color tone of said inverted electrical image signals.
Claim 6
Dependent Claim
83 words
A device for recording image signals of photographic pictures as recited in claim 1 further comprising: video signal processing circuit means for converting said electrical image signals produced by said means for producing into a digital image signal including a plurality of unit picture elements; an image memory for storing said plurality of unit picture elements in predetermined addresses; and varying circuit means for changing an orientation of an image represented by said plurality of unit picture elements responsive to a varying command.
Claim 7
Dependent Claim
23 words
A device for recording image signals of photographic pictures as set forth in claim 1, wherein said recording medium is a magnetic disc.
Claim 8
Dependent Claim
24 words
A device for recording image signals of photographic pictures as set forth in claim 1, wherein said print paper is a roll-shaped print paper.
