Latest Patents

Wei-Jen Li's latest patents include a method for 3:2 pull-down detection. In one embodiment, a 3:2 pull-down detection component of a video encoder uses motion vectors to determine whether a repeated field exists in a video sequence. The component utilizes field motion vectors determined by a motion estimator and compares these vectors to a threshold to identify repeated fields. If a repeated field is detected, the video encoder can eliminate it, enhancing the overall video quality. Another patent involves a video encoder with embedded scene change and 3:2 pull-down detection components. This invention features a two-phase motion estimation process, where the first phase determines a set of field motion vectors to execute the necessary detection components.
