摘要： Differences between an offline spectrophotometer and an inline spectrophotometer can result in differences between a hardcopy target color and a printed reproduction of that color. The inline spectrophotometer is inside of a printer and configured to measure printer output. As such, the inline spectrophotometer cannot conveniently measure the hardcopy target color. A printing error or an instrument offset can be determined and passed to a color correction module that updates the device dependent color specification associated with the given spot color. This color specification may be stored, for example, in the printer controller, and used when a document subsequently calls for that spot color, thereby providing accurate color reproduction from that particular printer incorporating that particular inline spectrophotometer.

摘要： This invention relates to a method and apparatus for implementing a trapping operation on a digital image during image processing. Some embodiments of the present invention provide an intelligent trapping process to compensate for registration errors or halo effect errors by an imaging device. At various times, a set of customized trapping parameters may be determined for the device based on its actual or estimated performance. The imaging device may be checked automatically on a periodic basis, in response to an event, or upon request. The trapping parameters may be unidirectional and may vary temporally or spatially. The imaging device can then print images based on its customized set of trapping parameters.

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.
