摘要： Halftone generating methods and systems convert continuous tone anti-aliased image data to halftone image data using halftoning techniques that efficiently use memory resources. One of a plurality of Holladay counters is selected and the address bits from the selected Holladay counter are output to a look-up table that efficiently stores various halftone screens. Halftone image data is then output. If necessary, the halftone image data is unpacked and replicated as required depending on the resolution requirements of the halftone screen.

摘要： The present invention is a super-scalar method and apparatus for the generation of halftone dot patterns in an image processing system. The super-scalar design employs at least one block of memory for the storage of at least one predetermined halftone dot pattern across a plurality of unique locations therein, and a sequencer for producing an index into said memory as a function of the position of the pixel along a scan line and the halftone dot characteristics. Also included is addressing circuitry for memory access control, to combine the index produced by said sequencer and a pixel value for the pixel to produce a memory address, the memory address being thereby employed to access one of said locations in memory and to cause said memory to output a signal representative of a portion of the halftone dot pattern stored at the unique addressed location.

摘要： An improved technique for compressing a color or gray scale pixel map representing a document using an MRC format including a method of segmenting an original pixel map into two planes, and then compressing the data or each plane in an efficient manner. The image is segmented such that pixels that compress well under a lossy compression technique are placed on one plane and pixels that must be compressed losslessly are placed on another plane. Lossy compression is then applied to the lossy pixel plane while lossless compression is applied to the lossless pixel plane.

摘要： A method and apparatus for compressing and decompressing electronic documents, with maximum intradocument independence, and maximum flexibility in optimization of compression modes. The method includes receiving documents containing unknown combinations of a plural data types, including combinations of scanned data, computer rendered data, compressed data and/or rendering tags; dividing the received image into strips of blocks determining from the image itself, which data types are present in each block; compressing data of each data type present in each block with a compression method optimized for its data type. Scanned data may be further segmented into plural scanned data types, where each data type is compressed in said compressing data step with a compression method optimized for said scanned image data type. If the received data type is compressed data, the process may include the additional functions of determining a compression ratio thereof, and accepting the compressed data for use as, or decompressing and recompressing the data, based on acceptability of said compression ration determination. An instruction set is generated that allows detailed decompression instruction data and image data to be combined with transmitted compressed data. A data structure is shown, which segregates data types and instruction data, and allows for block to block and strip to strip processing independence.

摘要： Disclosed is a method for processing raster image data and determining via a reference device (e.g., LUT), an amount of marking medium (toner, ink) to be used for printing a document. Then billing costs based on the amount of medium is determined. In particular, a calibration method may be performed on an apparatus to determine the amounts of medium used for that particular apparatus. The calibration method includes printing pages with test patches for a plurality of colors at a particular dot value (or density), and weighing similar printed test pages so that the amount of medium used to print colors at particular dot values is determined by subtracting a weight of the pages before printing from the weight of the printed test pages. The change in weight (or mass) of the medium is used to populate the reference device for that apparatus.

摘要： Vector halftoning and error diffusion are combined to provide a quantization method that yields high quality rendered images while demanding fewer system resources. For instance, the method is tolerant of resolution reductions in secondary or auxiliary channels to the vector halftoning process. Accordingly, these secondary pixel data channels can be sub-sampled and/or bit-depth reduced for transmission bandwidth conservation and/or reduction in data storage requirements. Restoring the resolution of the low resolution channels provides estimated image data to arrange or align with high resolution target channel data for the vector halftoning process. Error from marking decisions generated by the vector halftoning process is diffused to neighboring unprocessed pixels. The method also allows for the use of a small vector halftone threshold array while providing quantized images with fine texture and wide color gamuts. In some embodiments error diffusion is distributed according to vector error diffusion.
摘要翻译：组合向量半色调和误差扩散以提供量化方法，其产生高质量渲染图像，同时要求较少的系统资源。例如，该方法容忍向量半色调处理的次要或辅助通道中的分辨率降低。因此，可以对这些次级像素数据信道进行子采样和/或位深度降低，以便传输带宽保持和/或减少数据存储要求。恢复低分辨率通道的分辨率提供了估计的图像数据以排列或对齐用于矢量半色调处理的高分辨率目标通道数据。通过矢量半色调处理生成的标记判定出错，扩散到相邻的未处理像素。该方法还允许使用小矢量半色调阈值阵列，同时提供具有精细纹理和宽色域的量化图像。在一些实施例中，根据向量误差扩散分布误差扩散。
