Abstract
A touch screen controller includes input circuitry receiving touch data from a touch screen, and processing circuitry. The processing circuitry determines first coordinates of a touch at a first time, based upon the received touch data. A first threshold window is set about the first coordinates, with the first threshold window having a central point at the first coordinates, and a second threshold window is set about the first coordinates, with the second threshold window having a central point at the first coordinates and being larger than the first threshold window. Second coordinates of the touch are determined at a second time, based upon the received touch data, and where the second coordinates are not within the first threshold window but are within the second threshold window, the second coordinates are corrected based upon a distance between the second coordinates and the central point of the second threshold window.
