Abstract
A portable hand-held image recording device for generating and storing information representative of a two dimensional image includes a compact image scanning apparatus, a microprocessor, memory, and associated control software. The compact image scanning apparatus includes a light emitting diode array to provide a source of light, a focusing element to create a scan line on the image, a lens array to transmit light reflected off of the image, and an image sensor to convert the light reflected off of the image into electronic information. A scanning subassembly is provided to accurately track movement of the recording device across the image and to incrementally scan discrete portions of the image by controlling energization of the light emitting diode array.
