摘要： A gray pixel encoding scheme is used in combination with a halftoner and an imager to produce halftoned images. A halftoner and an imager can be totally separate because the gray pixel encoding allows the imager to decode them at any time. The encoded gray pixels require less bandwidth than explicit gray pixels and can be decoded by the imager in an optimal fashion for the characteristics of the specific printer being used. An imager produces a small partial pixel within a spot boundary. The subpixel produced is called a gray pixel. The gray pixel is allowed to grow from a zero width to a full spot width and is allowed to start anywhere within the spot. The pixel codes describe the starting positions of the gray pixels, the locations of the gray pixels within the spot, and the gray pixel width required. The imager uses the encoded gray pixel from the halftoner to produce a final halftoned image. The list of encoded pixels produced by the halftoner can be stored and used at a later time or sent through a network to a different imager to be printed out.
摘要翻译：灰度像素编码方案与半色调和成像器组合使用以产生半色调图像。半色调和成像器可以完全分离，因为灰度像素编码允许成像器随时对它们进行解码。编码的灰色像素需要比显式灰度像素少的带宽，并且可以由成像器以针对所使用的特定打印机的特性的最佳方式进行解码。成像器在斑点边界内产生一小部分像素。所生成的子像素被称为灰色像素。允许灰度像素从零宽度增长到整个光点宽度，并允许其在任意位置开始。像素码描述了灰色像素的起始位置，斑点内的灰色像素的位置以及所需的灰色像素宽度。成像器使用来自半色调的编码灰色像素来产生最终的半色调图像。由半色调生成的编码像素列表可以在以后存储和使用，或通过网络发送到不同的打印机打印输出。

摘要： In a printer, a controller keeps track of the imager's operation. The original image is transferred into a continuous tone image by using a tone reproduction curve. That signal is encoded into gray pixel data by a halftoner. The pixel data contains the pixel location and the desired darkness of gray, i.e., amount of toner deposited. An imager uses the pixel data to generate the final halftoned image in a printer. A controller generates a feedback signal based on the printer's operation and the quality of the final halftoned image. The imager uses the feedback signal to modify the encoded gray pixel data in order to adjust the final halftoned image. The original coding of the image into gray pixel data is generic and does not depend on the characteristics of the printer being used. This invention reduces the computation of gray pixel data and allows the imager to be separate from the apparatus generating the gray pixel data.
摘要翻译：在打印机中，控制器跟踪打印机的操作。通过使用色调再现曲线将原始图像转印成连续色调图像。该信号由半色调编码为灰色像素数据。像素数据包含像素位置和所需的灰色暗度，即沉积的调色剂量。成像器使用像素数据在打印机中生成最终的半色调图像。控制器基于打印机的操作和最终半色调图像的质量生成反馈信号。成像器使用反馈信号来修改编码的灰度像素数据，以便调整最终的半色调图像。将图像的原始编码变为灰色像素数据是通用的，并且不依赖于所使用的打印机的特性。本发明减少灰度像素数据的计算，并允许成像器与产生灰度像素数据的装置分开。

摘要： The present invention is a method and apparatus allowing the application of two or more distinct halftone types in the rendering of a single image. The invention employs a halftone selector of a threshold type, or as an alternative a segmenter type. The halftone selector determines which areas of an image will receive which type of grayscale halftone treatment on a pixel by pixel basis. Examples of various halftone types include stochastic, clustered dot, line screen, and other high addressability types. Each pixel of data is treated by the appropriate halftoner circuit which in response outputs digital data. A controller circuit remaps the digital data into the appropriate width and position signals for a pulse width position modulator, including any other signals as needed for any additional inverter circuitry. The pulse width position modulator generates a video signal which may be inverted by the inverter circuit as responsive to the controller circuit remapping determination. This final video signal is provided to an image output terminal.

摘要： The present invention is a method for image segmentation to produce a mixed raster content (MRC) image with constant foreground layers. The invention extracts uniform text and other uniform color objects that carry detail information. The method includes four primary steps. First, the objects are extracted from the image. Next, the objects are tested for color consistency and other features to decide if they should be chosen for coding to the MRC foreground layers. The objects that are chosen are then clustered in color space. The image is finally segmented such that each foreground layer codes the objects from the same color cluster.
