ABSTRACT:
A system in which a video camera scans one or more documents and generates analog electrical signals representative of the information on the documents. The signals may be converted to digital signals and stored in a suitable memory from which they may be recalled or they can be used to drive a microfilm or other printer which serves to print a representation of the document. The printer may be controlled so that the new document contains updated information as required, which information can be derived from another document being scanned by an additional video camera or from storage. The stored signals can be selectively recalled from storage, electronically manipulated and applied to the printer to provide a microfilm or print which may include updated information or be in a new format.
