Latest Patents

Carmen Tseng holds 2 patents related to her work in image scaling. Her latest patent describes a method and apparatus for two-dimensional image scaling. This method involves producing an output pixel datum from input pixel data by examining the brightness levels of several input pixels closely associated with the output pixel. The process determines whether to implement a less complex graphics-optimized scaling procedure or a more sophisticated video-optimized scaling procedure. In cases requiring advanced processing, directional interpolation is performed across multiple directions to identify the minimum brightness level gradient. The method generates several intermediate pixels, which are aligned perpendicularly to the gradient direction, and their brightness levels are calculated using linear interpolation. The final output pixel brightness level is derived from these intermediate pixels through appropriate filtering techniques, such as polyphase FIR filtering.
