With a patent to his name, Zimmerman has brought forth a solution that improves the conversion of interlaced to progressive video signals.

Latest Patents: Zimmerman's most notable patent is the "Weighted Median Filter Interpolator." This invention proposes a filter interpolator that can convert interlaced video signals to progressive formats. Depending on the available or processable source fields, the filter can be adjusted to utilize either a three-tap or a five-tap weighted median interpolator. The design ensures that the median samples processed are always an odd number, thereby optimizing the output quality. The five-tap mode further enhances the performance of the filter by using a three-dimensional aperture that spans horizontal, vertical, and temporal dimensions across three consecutive fields of the incoming interlaced video signal.
