Abstract
Abstract A system for generating new documents (20) from originals (4) containing text and/or images (22,28) employing e.g. a camera-projector system (6,8) focussed on a work surface (2), in conjunction with a copier or printer. In use, the camera 6 captures various manual operations carried out by the user, e.g. by pointing with fingers and tapping on the surface on the text or images (22,28) in an original paper document (4) on the surface (2) and representing manipulations of the text or images (22,28). Feedback to the user is provided by projection of an image (21,24) onto the surface or onto the original, or using some other visual display.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
A copying system, comprising: a work surface (2); means (8) for displaying images on the work surface; a camera (6), focussed on the work surface, for generating video signals representing in electronic form image information present within the field of view of the camera; processing means (10) for recognising one or more manual operations relating to the image information which are executed by a user within the field of view of the camera, and for performing electronic operations, corresponding to said manual operation(s), on the electronic form to produce a modified electronic form; the displaying means (8) being adapted to display, under the control of the processing means (10), simultaneously with or subsequent to said electronic operation performing step, images defined by said manual operations; and wherein said images defined by said manual operations include an image of the newly created document.
Claim 2
Dependent Claim
21 words
The copying system according to claim 1, wherein the modified electronic form includes an electronic version of a newly created document.
Claim 3
Dependent Claim
25 words
The copying system according to claim 2, further including means (208) for printing a document corresponding to at least part of said modified electronic form.
Claim 4
Independent Claim
123 words
A method of generating documents, comprising: providing a work surface, means for displaying images on the work surface, and a camera focussed on the work surface, said camera generating video signals representing in electronic form image information present within the field of view of the camera; recognising one or more manual operations relating to the image information which are executed by a user within the field of view of the camera; performing electronic operations, corresponding to said manual operation(s), on the electronic form to produce a modified electronic form; displaying, simultaneously with or subsequent to said electronic operation performing step, images defined by said manual operation(s); and wherein said images defined by said manual operations includes an image of the newly created document.
Claim 5
Dependent Claim
20 words
The method according to claim 4, wherein the modified electronic form includes an electronic version of a newly created document.
Claim 6
Dependent Claim
28 words
The method according to claim 4 or 5, further including the step of supplying to a printing device said electronic version; and printing out said newly created document.
Claim 7
Dependent Claim
32 words
The method according to claim 6, wherein said manual operation(s) include selecting a portion of text or image information in a document (4) located within the field of view of the camera.
Claim 8
Dependent Claim
19 words
A programmable printing apparatus when suitably programmed for carrying out the method of any of claims 4 to 7.
Claim 9
Dependent Claim
146 words
A copying system, comprising: a work surface (2); means (8) for displaying images on the work surface; a camera (6), focussed on the work surface, for generating video signals representing in electronic form image information present in at least first and second documents within the field of view of the camera; processing means (10) for recognising one or more manual operation(s) which are executed by a user within the field of view of the camera and represent the transfer of image information from the first document to the second document, and for performing electronic operations, corresponding to said manual operation(s), on the electronic form of said second document to produce a modified electronic form; the displaying means (8) being adapted to display, under the control of the processing means (10), simultaneously with or subsequent to said electronic operation performing step, images defined by said manual operations.
Claim 10
Dependent Claim
50 words
An interactive image reproduction system, comprising: a plurality of workstations interconnected by a communications link, each workstation comprising a system according to any of claims 1 to 3, 8 or 9, each workstation being adapted for displaying the video output from the camera (6) of the or each other workstation.
