Latest Patents
One of Weichun Ku's latest patents focuses on "Image statistics for motion detection." This invention relates to generating motion vectors through an image signal processor that includes a statistics circuit and a vector correlation analysis circuit. The statistics circuit determines image statistics, such as vectors representing sums of pixel values of rows or columns of blocks of an image. Additionally, it may mix or aggregate sums of multiple color components. The vector correlation analysis performs cross-correlation between vectors of a current image and reference vectors of a prior image to determine cross-correlation scores. This analysis generates a motion vector by identifying shifts in horizontal and vertical directions corresponding to peak values of cross-correlation scores.
Another notable patent is titled "Parallel bypass and regular bin coding." This system and method aim to improve the operational efficiency of a video encoding pipeline used to encode image data. The video encoding pipeline includes a transcode pipeline that provides entropy encoding of binarized syntax elements. In this embodiment, multiple bins may be encoded in parallel, resulting in increased encoding throughput.
