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： A printing system for rendering marks on a recording medium receives a multi-level grey scale pixel value representing a pixel having a first resolution. A screening circuit generates a screened multi-level grey scale pixel value equal to (G.sub.L -V.sub.i)+(S.sub.i -Th)*Dmp.sub.vi *Mod.sub.Eff wherein G.sub.L is the maximum grey level value of the pixel, V.sub.i is equal to the multi-level grey scale pixel value of the first resolution, S.sub.i is equal to a screen value corresponding to a position of the pixel, the image classification of the pixel and a brightness/darkness setting, The threshold value, Dmp.sub.vi is a video dependent dampening factor, and Mod.sub.Eff is a modulation multiplication factor. An interpolator converts the screened multi-level grey scale pixel value to a second resolution, the second resolution being higher than the first resolution, and a binarization circuit binarizes the converted multi-level grey scale pixel value so as to output a binary signal and an error value, the error value having a resolution equal to the first resolution. The error value is diffused to multi-level grey scale pixel values corresponding to pixels adjacent to the pixel having the first resolution, and the binary signal is converted into a mark on the recording medium.

摘要： A method and system automatically determines proper background values for a document. A histogram of the document is generated and it is determined whether a background characteristic of the document is uniform. If the background is uniform, a white background value is set equal to a first calculated white peak value. If the background is non-uniform, the white background value is set equal to a second calculated white peak value. A foreground value of the document is analyzed for validity when it is determined that a background characteristic of the document is uniform. A black background value is set equal to a black peak value calculated from the histogram when it is determined that a foreground value of the document is valid.

摘要： Systems and methods are described that facilitate identifying objects in a document (e.g., a PDF document) for automatic image enhancement (AIE). A PDF document is “chunked” or segmented into chunks, and boundaries between chunks are identified as real or imaginary. Chunks sharing imaginary boundaries are combined, while real boundaries are retained, to generate “de-chunked” objects. These objects are then classified, and an AIE application is executed on objects meeting pre-specified classification criteria. In this manner, objects of r which AIE is not desired are not subjected to the AIE application, thereby saving time and processing resources associated with enhancing the document.
摘要翻译：描述了便于识别用于自动图像增强（AIE）的文档中的对象（例如，PDF文档）的系统和方法。 PDF文档被“分块”或分割成块，并且块之间的边界被识别为实部或虚构。组合共享虚拟边界的块，而保留实际边界，以生成“去分块”对象。然后对这些对象进行分类，并在符合预先指定的分类标准的对象上执行AIE应用程序。以这种方式，不需要AIE的对象不进行AIE应用，从而节省与增强文档相关联的时间和处理资源。

摘要： A photosensitive imaging apparatus has a linear array of groups of photosensors. In a low-resolution scanning mode, all of the photosensors in each group act together as one large photosensor. In a high-resolution scanning mode, each photosensor in a group acts outputs image-based signals independently. In either mode, the signals output by the photosensors are transferred to one of two output lines, such as for “odd-” and “even-” positioned photosensors or groups of photosensors. The signals on the two lines can then be multiplexed to a single output line. The dual output lines enable fast signal output in either resolution mode.
