Abstract
A system is disclosed for the editing of electronic documents wherein the hardcopy of an original document is scanned into digital form to provide an electronic version of the document. The original document is then placed on an x-y digitizer with the position of the original document being correlated with the electronic version of the document in order to provide corresponding scaling, rotation and offset of the documents. The original document is then edited with a digitizer pen that marks the original document while at the same time converting the handwritten edit into digital form. The digitized edit is then combined with the electronic version of the document to produce an edited electronic document that can be displayed on a local and/or remote computer screen or the like. The system is useful in such applications as teleconferencing, where it is desired to edit the electronic version of a document that is displayed at multiple locations. Other applications include editing of digitized medical documents and graphical images such as X-rays, creating and editing drawings for engineering and other purposes, and editing digitized documents for archival purposes.
