摘要： The present application provides a mixed resolution, interleaving-based, cross-channel data flow and data format for a printer image path. The architecture provides pixel data for a colorant of a given writing channel at its nominal (full) resolution, while pixel data for other colorants is provided at lowered resolution. Pixel data for a primary channel at its full resolution is interleaved with data for other secondary channels at lower resolution. Known sub-sampling or compression techniques can be used to lower the resolution of the secondary channels. The data at the different resolutions is generated by the digital front end (DFE), which distributes the data for each writing channel at the time it is needed. Preferably, the low resolution data is sent first to the writer, followed by high resolution data, so that data buffering is minimized.
摘要翻译：本申请提供了用于打印机图像路径的混合分辨率，交织，跨通道数据流和数据格式。该架构以其标称（全）分辨率为给定写入通道的着色剂提供像素数据，而以较低分辨率提供其他着色剂的像素数据。用于其全分辨率的主要信道的像素数据与较低分辨率的其他次要信道的数据进行交织。已知的次采样或压缩技术可以用于降低次级通道的分辨率。不同分辨率下的数据由数字前端（DFE）生成，数字前端在需要时分配每个写入通道的数据。优选地，低分辨率数据首先发送到写入器，随后是高分辨率数据，使得数据缓冲被最小化。

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。

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： A method and system is provided for splitting a print job into its preamble and at least one chunk. The splitter maintains a collection of RIP node addresses to which chunks of the job currently being split have already been sent. When a new chunk is about to be sent, the splitter checks whether each RIP node address has already received a chunk. If the RIP node has not already received a chunk, the splitter sends the preamble as well as the chunk to an available RIP associated with the RIP node. If, however, the RIP node address has already received a chunk, only the portion of the chunk after the preamble is sent to an available RIP associated with the RIP node and communicate the location of the preamble to the available RIP node. The preamble may contain common content for each job.

摘要： There is disclosed in embodiments methods relating to the compression of printing hints. The method in embodiments generates a first set of image pixels having corresponding printing hints. The printing hints are then adjusted to produce a second set of image pixels processed in such a way that an end printed result is visually equivalent to a printed result using the first set of image pixels thereby reducing the entropy in the printing hints. The method improves the compression ratio of an image using printing hints by adjusting the printing hints of pixels that are zero or fully saturated. The printing hints are adjusted in such a way to reduce the complexity of the printing hints.
