MICROFILMING SYSTEM WITH ZONE CONTROLLED ADAPTIVE LIGHTING Abstract of the Invention A system for producing image of documents is disclosed. The system provides varying levels of illumina- tion to different areas of the document being recorded, depending upon relative image densities across the document. A slit aperture image area is divided into a plurality of illumination zones and the image density of each zone is sensed and adjusted individually. Efficient and orderly unattended off-loading of photographed documents is accomplished by a movable drawing member over which large documents are automatically draped, properly collated. A catch tray is provided for automatically off-loading and collating smaller documents. - - - - - - -
