摘要： Optimally determined halftoning algorithms are applied to tone values by selecting among combinations of at least two algorithms that best address the tradeoff between output quality and rendering performance. Input tone values are scrutinized and matched with the algorithm combination that processes the associated tone values in a manner that increases performance (including data compressibility) without sacrificing output quality. The selection process is computationally simple and fast. Reliability is ensured because the combinations of halftoning algorithms are tabulated as a result of analysis of test samples of the printed output.
摘要翻译：通过选择最佳地解决输出质量和渲染性能之间权衡的至少两种算法的组合，将最佳确定的半色调算法应用于色调值。输入音调值被仔细检查，并与以不影响输出质量的方式提高性能（包括数据压缩性）的方式处理相关音调值的算法组合相匹配。选择过程计算简单快捷。由于打印输出的测试样本的分析结果列出了半色调算法的组合，因此确保了可靠性。

摘要： Tone dependent plane dependent error diffusion halftoning takes into account multiple color planes, such as cyan and magenta, when determining the placement of a dot in any of the color planes. The combined tones of the correlated color planes is used to determine the threshold levels against which the combined tones and the accumulated errors for the correlated color planes is compared. Further, tone dependent error weightings are determined based on the combined tones of the correlated color planes. The tone dependent error weightings are used to diffuse the final accumulated errors for each color plane. A prerendered mid-tone bitmap may be used to break up any structured patterns that occur in the mid-tones. Using this technique, printed dots of two or more colors are dispersed so as to avoid noticeable clumping of dots of two or more colors to provide a more uniform pattern and to avoid the unintentional overlapping of colors. This technique can be used to augment any existing error diffusion method.

摘要： A technique is described to greatly reduce or avoid the quantization errors that occur when mapping a relatively linear RGB color space into a greatly non-linear printer CMY color space of equal precision, avoiding the contouring or banding that occurs when printing color gradients in a non-linear printing system. The technique performs a dither-like process on the original RGB continuous tone data. The RGB values are dithered to create a range of values that, when mapped to the non-linear printer continuous tone CMY values, creates a range of CMY values that, on average, represent the correct average tone of the input RGB values. The generated CMY continuous tone values are then halftoned and printed.
摘要翻译：描述了一种技术，以大大减少或避免将相对线性的RGB颜色空间映射到相当精度的非常非线性的打印机CMY颜色空间中时发生的量化误差，避免了当在非打印机中打印色彩渐变时发生的轮廓或条带线性打印系统。该技术对原始RGB连续色调数据执行类似抖动的处理。 RGB值被抖动以创建一定范围的值，当映射到非线性打印机连续色调CMY值时，创建平均来说表示输入RGB值的正确平均色调的CMY值的范围。然后将生成的CMY连续色调值半色调并打印。

摘要： When a monitor display is to be printed by a color printer, the present invention transforms the monitor colors to compensate for chromatic adaption while mapping the monitor's neutral axis with the printer's neutral axis so neutral colors remain neutral. In the preferred embodiment, it is assumed that there is only partial chromatic adaption by the viewer. The result is that printing the transformed monitor colors using a color printer causes printed colors to appear to the human eye to be similar to the displayed monitor colors, while preserving neutral colors, once the human eye has adapted to the displayed monitor colors and the printed colors.

摘要： A data resolution synthesis algorithm takes low resolution source input data (e.g., data degraded from compression or data acquired from low quality imaging devices) to synthesize high resolution output data. In an exemplary embodiment for color printing, the algorithm is performed by characterizing a multi-pixel area, or window, around a pixel that can benefit from resolution enhancement. To interpolate to a high resolution output a set of spatial filters is applied to the data area based on the window characterization. The output of the resolution synthesizer is a set of multiple pixels for each input pixel, representing the source input pixel in a higher resolution enhanced version. The filters are chosen from a stored data base (generic or specifically applicable data base for each type input device) created to fit input/output device requirements.
