Latest Patents

Francis Ganapahti holds a patent for "Modulo addressing for look up table screening for printing files in a page description language." This invention involves approximating a gray scale tone with a more limited range image producer, a process known as screening. The invention reduces the time needed for such screening by discriminating when screening is not necessary. In a first embodiment, the rendering process produces a minimally enclosing bounding box surrounding all rendered objects. In an alternative embodiment, scan lines that include any part of a rendered object are noted. The screening process makes better use of memory by dividing each row of a preference matrix into segments. The lookup tables associated with these segments are sequentially loaded into a memory cache. Input pixels mapping into the loaded segment lookup tables are screened. Subsequently, the lookup table associated with the next segment of the preference matrix is loaded into the memory cache and used to screen input pixels mapping into that segment. The method packs two output pixels into a single data word while multi-level screening, even when the preference matrix has an odd row length, by alternating consideration of M−1 input pixels and M+1 input pixels, where M is the row length.
