Latest Patents

One of his latest patents is titled "Storage of stamp information for error diffusion." This patent describes a method and system for processing image data in an image processing device across multiple pixel positions within several scanlines. The system involves storing a starting stamp value and a range of delta stamp values for the scanline. These stored values are utilized to generate a pixel stamp value for an input pixel by adding either a starting value or a previous pixel stamp value to the stored delta stamp value. The method also includes receiving an input pixel intensity value and determining an output pixel intensity value. If the output pixel intensity value matches a specific value for a dot or hole, the delta stamp values for adjacent pixels can be updated accordingly.

Another significant patent is related to "Bitmapped based trapping methods, apparatus and system by modifying non-black halftone pixel bitmap plane using estimated continuous tone value." This patent provides methods and systems for black trapping color image data by estimating continuous tone values associated with non-black pixels near qualified black pixels. The estimated values are then halftoned at the black pixel locations and combined with the original bitmap data.
