摘要： What is provided are a novel system, method, and computer program product for estimating the amount of color in a document to be printed, with the capability to handle composite black. A color billing strategy can be dynamically determined based on the amount of color in the document. In one embodiment, a contone CMYK image is examined and the level of color is estimated based on information extracted from the four planes simultaneously. More specifically, it examines the pixel values from all the four planes to calculate the number of white, black, color, and gray or neutral pixel counts. Input CMYK values can be pre-adjusted via a look-up table to take into account neutral balance characteristics. The difference among the adjusted color values is compared against a threshold that is input level dependent. Color is further subdivided into fuzzy colors to handle highlights and neutral areas.

摘要： A method for dynamic range adjustment of image data of a captured image by determining a white point of an image. The method also involves determining a black point of the image, classifying pixels of the image, and determining an offset value for a pixel of the image based on the determined black point of the image and the determined classification of the pixel. Dynamic range adjustment of the image data is performed using the determined offset value for the pixels of the image and the determined white point of the image.

摘要： In a digital reproduction system incorporating a single pass scanner, accurate image processing results from processing a subset of grayscale image data. More specifically, scanlines that correspond to the leading edge of a document are stored and processed to detect skew and to obtain an appropriate correction. The lead edge correction is then applied to the entire grayscale image. Accordingly, the present systems and methods eliminate skew from grayscale images in real-time. The corrected image is rendered to binary and stored in electronic pre-collation memory and cropping, masking and other image editing operations can be performed on the binary image data before the image is printed.

摘要： This invention relates to an imaging device that extends the processing of resources to data having a greater bit-depth. A signal having data at the first bit-depth is received, and at least a portion of the data at the first bit-depth is converted into an estimated value that is at the second bit-depth. A residual that indicates a difference between the data and the estimated value is determined. The estimated value is processed through the resource to form processed data that is at the second bit-depth. The data is then substantially recovered at the first bit-depth from the processed data that is at the second bit-depth and based on the residual.

摘要： In an image processing system, successive segmentation steps are carried out. In the case of a “hole” in the segmentation result, which is defined as a small area of one type (such as black) within a slightly larger “island” of another type (such as white), a basic segmentation technique may result in an error. The error is avoided by retaining, for each distinct area in the image, a variable indicating whether the area has been “flipped” from one type to another in a previous processing operation.
摘要翻译：在图像处理系统中，执行连续的分割步骤。在分割结果中的“孔”的情况下，其被定义为在另一种类型（例如白色）的略大的“岛”内的一种类型（例如黑色）的小区域，可能导致基本分割技术在一个错误。通过为图像中的每个不同区域保留指示在先前处理操作中该区域是否已经从一种类型“翻转”到另一种类型的变量来避免错误。
