First Claim
Patent Images
1. A method for adjusting pixel values within a frame to be displayed, comprising:
- receiving coordinates and pixel-adjustment values for one or more control points within the frame;
calculating pixel-adjustment values for pixels in the frame based on the coordinates and the pixel-adjustment values for the one or more control points;
applying the pixel-adjustment values to the pixels within the frame; and
displaying the frame.

Abstract
A system that adjusts pixel values to produce visual effects in a frame to be displayed is presented. During operation, the system receives coordinates and pixel-adjustment values for one or more control points within the frame. Next, the system calculates pixel-adjustment values for pixels in the frame based on the coordinates and the pixel-adjustment values for the one or more control points. The system then applies the pixel-adjustment values to the pixels within the frame and displays the frame.
