Latest Patents
Williamson's latest patents include a "Method and apparatus for non-linear dithering of digital images." This invention addresses the human eye's sensitivity to intensity variations, particularly at low levels. By employing a piecewise linear quantization strategy, it produces higher quality dithered images. The method divides input intensity values into sub-ranges, allowing for greater accuracy in low intensity levels where the eye is most sensitive.
Another significant patent is the "Method and apparatus for vector aligned dithering." This invention aligns the dither matrix to the vector rather than the display coordinate space. By ensuring that the dither matrix corresponds to the vector's major axis, it enhances the simulation of original intermediate intensities in the dithered pixels.
