Latest Patents
One of his latest patents is titled "Method of determining and storing color printing information." This innovative method involves generating a set of three gray mapper curves to determine the necessary color correction values for duplicating a sample set of color chips. The process utilizes specific inks and paper to ensure accurate color reproduction. The generated correction percentages are then applied to input color values to produce corrected color values, which can be adjusted for variations in black ink.
Another notable patent is "Method of color conversion with improved interpolation." This apparatus is designed to convert a color image from one color space to another. It includes a memory that stores a finite number of output signals representing colors in the output space. The interpolation process takes into account the four closest color values in the memory to derive an accurate output color value for an input color.
