摘要： Selective edge softening and selective edge dithering is introduced into an image representation to improve local control where halo problems are expected. Selective areas of dilation are isolated and separately dithered or halftoned, the result of which is then swapped back into or substituted for the stored original image. In this manner misregistration and color plane-to-plane interactions can be compensated for in plural image forming station architecture systems. The same technique is also valuable in monochrome systems as an aid to overcoming edge displacement and slow toner problems when the selective edge softening is selectively applied to edges which are in particular perpendicular to the fast scan direction.

摘要： Disclosed is a processor-implemented method for processing image data comprising a plurality of pixels and system for performing the method. The method includes the following acts: determining at least one type of data represented by the plurality of pixels, determining, for each type of data, a number of pixels from the image data representing that type of data in the image data, and determining a compression scheme for compressing the image data based on a relative or absolute amount of each type of data in accordance with a predetermined scheme. The type of data may be determined by received input (e.g., user selected type and compression quality) or by analyzing its pixels and comparing it to thresholds. Basing the compression technique on the data type allows for better selection of a compression technique (e.g., MRC or JPEG), and thus greater image quality, compression ratios, and file size.
摘要翻译：公开了一种用于处理包括多个像素的图像数据的处理器实现的方法和用于执行该方法的系统。该方法包括以下动作：确定由多个像素表示的至少一种类型的数据，对于每种类型的数据，从表示图像数据中的该类型的数据的图像数据中确定一数量的像素，并且确定压缩方案，用于根据预定方案基于每种类型的数据的相对或绝对量压缩图像数据。数据的类型可以由接收的输入（例如，用户选择的类型和压缩质量）或通过分析其像素并将其与阈值进行比较来确定。基于数据类型的压缩技术可以更好地选择压缩技术（例如，MRC或JPEG），从而更好地选择图像质量，压缩比和文件大小。

摘要： A method permitting an end user to recalibrate a color reproduction device. The color reproduction device includes a device for converting the native color values of the scanner into a device independent color space, a test target, and the desired values of each patch of the test target. The method includes printing the test target and scanning it with a scanner that forms a part of the color reproduction device. The device compares the desired values with the values obtained from scanning the printed test target to obtain a set of adjustment values to compensate for drift in the output of the color reproduction device. The compensation emphasizes restoration of the overall gray balance of the color reproduction device and can be implemented by modifying the tone reproduction curves or the halftone process used in the color reproduction device.

摘要： Disclosed is a processor-implemented method for processing image data representing a document using an image processing apparatus. The processor receives image data, determines the classifications and counts of pixels in the image data (e.g., in device independent space that are degrees of neutral or non-neutral), classifies the image data into a category based on the determination of classifications and counts of pixels, and determines a billing structure for the image data based on the classification of image data. The classification can be performed on the image data prior to conversion into device dependent space. For example, by counting true color, neutral, non-neutral, and fuzzy color pixels and comparing them to thresholds, the image data can be classified as neutral or very colorful. By classifying images earlier in the image path, errors in billing are reduced.

摘要： Disclosed herein is a system and method for diagnosing a failure condition of an image processing apparatus. When a failure condition is detected in an image path during output of a document, a fault code is issued. The image processing apparatus is then capable of performing an internal diagnosis to generate a diagnostic report, and send the diagnostic report and fault code to an operator at a remote location. The system and method allows one to diagnose a problem or failure condition more quickly and efficiently, thereby cutting down on service time and costs.
