Latest Patents

David holds a patent for a "System and method for producing video effects on live-action video." This digital video effects system operates in real time and includes an address generator with a pair of 2-D tables that provide x-coordinate and y-coordinate offset values. A third 2-D table contains warp activation factors, which are scaled using a clip and gain processing technique to produce scaled activators. These activators are then used to adjust the x- and y-offset values, which are combined with the original raster-order addresses to generate frame buffer readout addresses. The system produces an output video signal through an inverse mapping of the input frame buffer. The 2-D tables allow for pixel-by-pixel control of the image, enabling a variety of effects by simply changing the tables.
