Latest Patents

One of Schwendowius's notable inventions is the "Raster Scan Conversion System for Interpolating Interlaced Signals." This invention addresses the challenge of converting interlaced video signals into progressive formats using an advanced interpolation algorithm (IPC algorithm). The algorithm is scalable across multiple levels of complexity, tailored to available resources such as computational power, memory, and bandwidth. The system features an IPC mode control implemented through a decision table, allowing for configurations ranging from simple line repetition to more complex linear and median inter-field computations.

Another significant patent is the "Weighted Median Filter Interpolator." This invention proposes a filter for the interlaced to progressive conversion of video signals that can adapt the filter interpolator mode based on the available source fields. The system realizes either a three-tap or five-tap weighted median interpolator by selecting appropriate weights, ensuring that the processing involves an odd number of median samples. The five-tap weighted median IPC filter enhances output quality by using a three-dimensional filter aperture that spans horizontal, vertical, and temporal dimensions of incoming interlaced video signals.
