Apparatus for selecting and displaying areas on an original document which are to receive special editing. High intensity light passing through a liquid crystal device (LCD) is projected through the document to highlight the selected areas. Control of the electronic shutters in the LCD is responsive to the coordinate data entered by the digitizing apparatus. The complete area can be highlighted as well as only highlighting a border around the designated area. Specific color can be used for highlighting the selected area to provide additional information as to the type of editing to be performed within the selected area.
