ABSTRACT:
A method and apparatus for aligning a first coordinate system of a digitizing panel with a second coordinate system of a display device. The method includes the steps of displaying a plurality of reference points on the display device, each of the reference points having a X.sub.ref, Y.sub.ref coordinate value, determining a plurality of first Xr, Yr coordinate values from the digitizing panel which are indicative of a plurality of positions of an object positioned relative to the plurality of reference points, determining a plurality of channel gain correction values from the plurality of first Xr, Yr coordinate, values and the plurality of X.sub.ref, Y.sub.ref coordinate values, and storing the plurality of channel gain correction values for use in correcting a second Xr, Yr coordinate value which is indicative of a position of an object relative to the digitizing panel.
