Latest Patents

Wredenhagen's latest patents include a "Method and apparatus for motion adaptive deinterlacing." This invention involves an adaptive filter that calculates a target pixel from an interlaced video signal. The video signal consists of multiple frames, each containing an even and an odd field. The filter features a quantized motion calculator that estimates the amount of motion around the target pixel, while the filter selector chooses a filter based on this estimated motion. The filter applies different weighting factors to current and previous field pixels to create the target pixel.

Another significant patent is the "System and method for scaling images." This invention provides a system for calculating a target pixel for scaling an image made up of several source pixels. It determines a contour in the image using a set of predetermined parameters. The filter tap configuration is adaptively selected from a predefined set based on the determined contour, allowing for the calculation of the target pixel by convolving the source pixels with a weighting factor.
