Latest Patents
One of his latest patents is titled "System and method for transitioning between two filters, allowing for the use of higher order interpolation." This invention provides a system, apparatus, and method for filtering an image that produces output images with high resolution without visual discontinuity across a wide range of resize ratios. The invention includes a linear filter for source images requiring low magnification and a higher order filter for those requiring high magnification. In the transition region, an interpolation is performed between the linear and higher order filters to ensure a smooth transition in filtering and magnification, resulting in a high-quality output image.
Another significant patent is the "Floating point gamma correction method and system." This invention offers a method, device, and system for performing gamma correction on a set of pixel data based on a gamma correction curve table. The method includes partitioning the gamma correction curve table into segments associated with intensity levels, ensuring that significant banding effects are not visible to the human eye. The gamma corrected pixel values are stored for each segment, allowing for efficient gamma correction of pixel data.
