摘要： A system and method for defringing chromatic aberrations that occur in imaging devices such as scanners. The system comprises shift filters to shift lines in the various color planes together. In addition in each color plane, a spread filter is used to compensate for the unequal point spread functions of each color. Furthermore, the results can be enhanced by filtering in the luminance-chrominance space.

摘要： The present invention solves the problem set forth above by providing a method for accelerating the production of a standalone copy of a document by a peripheral device. The invention employs a white space map of the document to be copied. The map is generated by the ASIC chip and is used by the device to identify areas of the outputted copy that do not require ink or toner. This reduces the processing resources necessary to print the copy, thus speeding up copy production.

摘要： A processor is provided that includes a primary memory of a processor and color conversion logic. The primary memory is to store a first color look-up table (LUT) related to a second color space. The color conversion logic is responsive to a received set of pixels, where each pixel of the set of pixels includes a color value in a first color space. The color conversion logic includes decision logic to selectively access the first color LUT and a second color LUT of a secondary memory to obtain a color value of the second color space that is associated with each pixel of the set of pixels based on a comparison of each pixel to at least one neighboring pixel.

摘要： Provided herein is a method for accelerating the production of a standalone copy of a document by a peripheral device. The invention employs a white space map of the document to be copied. The map is generated by the ASIC chip, preferably at an early stage in the processing pipeline, and is used by the device to identify white areas of the outputted copy that do not require subsequent image processing calculations and do not require ink or toner markings on the paper. Use of the white space map allows the system to reduce the processing resources necessary to image process and subsequently physically print the copy, thus speeding up copy production.

摘要： A method of rotating a digital image includes performing a first pass to process a selected image tile of a source image. The first pass includes copying a set of pixels of the selected image tile from a first memory to a processor memory, where the set of pixels comprises a portion of the selected image tile. The first pass further includes grouping the set of pixels into blocks of pixels and writing each of the blocks of pixels to a memory location. The method further includes repeating the first pass until each of the pixels of the selected image tile is processed, performing a second pass to process the blocks of pixels, and repeating the second pass until each of the blocks of pixels is processed. The second pass includes copying blocks of pixels, regrouping the blocks of pixels, and writing the regrouped pixels to a destination image location.
