Latest Patents

One of his latest patents is a "Device for removing mosquito noise and associated method." This invention provides a solution to adaptively determine the proper strength for removing mosquito noise based on image complexities. The device includes a buffer, a lookup table, and a strength determining unit. The buffer stores a pixel matrix with a target pixel, while the lookup table contains various coefficients. The strength determining unit detects image complexities and outputs a strength coefficient for effective noise removal.

Another significant patent is the "Adaptively de-blocking circuit and associated method." This invention derives a mean from neighboring pixels surrounding a central pixel in an image. A blending factor is determined based on the flatness of the image. The updated pixel value of the central pixel is calculated by blending the original pixel value with the mean according to the blending factor. The updated pixel value can be output in response to a block border signal.
