Abstract
A system and method of geometrical predistortion of a graphical source signal is provided in which the graphical source signal is merged with an input video signal for display on a display device. The input video signal is received at a hardware scaler device and a predistorted video signal is generated there from. A warping map is calculated using a programmed processor and a graphics source signal is then predistorted, in software, using the warping map to generate a warped graphical overlay signal. The predistorted video signal from the hardware scaler is then merged with the warped graphical overlay signal from the programmed processor.
