ABSTRACT:
A method for using a scanner to scan pixel data from an image on a page and map the scanned pixel data in a computer's memory is disclosed comprising the steps of (a) placing a scanner having an elongated detector array of detector elements and two optical mice located in relation to the ends of the array on a transparent grid pattern covering an image on a page to be scanned, (b) determining the orientation of the scanner with respect to the grid pattern using motion detection information provided by the two mice, (c) positioning the scanner at a starting point from which to start detecting the position of the mice and commencing scanning of the page by moving the scanner across the surface of the grid pattern, and (d) storing pixel data scanned by each detector element at a memory address of a computer in communication with the scanner which corresponds to a coordinate position on the grid pattern determined to be nearest the actual position of a particular detector element.
