1. An interactive projector comprising:

  • generating means for recording an image of a document and for storing the image digitized image data in a memory;

    image enhancement means, coupled to the generating means, for enhancing the digitized image data and storing the enhanced digitized image data in the memory;

    resolving means, coupled to the memory, for resolving as an enhanced image the enhanced digitized image data;

    projection means for projecting the resolved enhance image onto a display surface;

    input means including a coordinate input array corresponding to the resolved enhanced image, for receiving user input indicative of a desired modification to the resolved enhanced image and for responsively generating user input signals;

    image modification means, coupled to the input means and to the resolving means, for processing the enhanced digitized image data in accordance with the received user input signals to produce modified image data for resolution by the resolving means, wherein the image modification means is operative to edit, annotate, and re-size the resolved enhanced image in accordance with the received user input signals and a set of image modification rules, and storing the user input signal in the memory; and
