摘要： A method for embedding “no-scan” or “no-copy” information in a document border includes encoding information as a plurality of data carrying dot pair patterns. For each page of a document to be rendered, the method includes determining whether the border area is blank. If found not blank the border area is cleared. Each of the plurality of data carrying dot patterns is embedded in the blank border area of the document page. The document page with the embedded data carrying dot patterns is then rendered, where each data carrying dot is too small to be visually noticeable.

摘要： A method and apparatus for digital image reduction using an improved “extendible” perspective projection technique which allows for flexible control of the averaging cell or window size separately from the reduction ratio to improve moir{acute over (e)} suppression or sharpness as desired in the resulting reduced-size image. The extendible perspective projection technique can also be implemented together with ordinary perspective projection or together with a combined one-dimensional filter and linear interpolation technique to produce a reduced-size image of a quality comparable to those produced by the prior technique of using a two-dimensional pre-filter prior to interpolation at a much lesser cost due to the reduced number of required scanline buffers.

摘要： Embodiments herein observe the backing of the document handler to determine if a document was left on the platen and would block the scan head from scanning the documents as they are moved by the document handler. An embodiment herein comprises a transparent platen and a document handler on a first side of the platen. The document handler has a backing, and the backing is adapted to move media within the document handler. A scan head is positioned on a second side of the platen. The scan head remains stationary when scanning the media being moved by the document handler and the scan head moves when scanning media on the platen. The backing of the document handler has a surface that is distinguishable from the media such that the scan head can detect whether the media is on the platen and would block the scan head from scanning the media being moved by the document handler.

摘要： A method and system to convert an image described in a page description language to a contone image. The contone image is halftoned and encoded to generate image data including edge tag data and image data. A tagged state value of each pixel of image data within a predefined neighborhood of pixels is determined. The image data is filtered using a predetermined set of filter weighting values wherein each pixel of image data within the predefined neighborhood of pixels has an associated filter weighting value. A predetermined filtered image value is assigned to each pixel having a tagged state indicating an edge pixel. A summation of all filtered image values for the predefined neighborhood of pixels is assigned when the tagged state of the pixel is a non-edge pixel.

摘要： A method and system implements selective, memory efficient, control over the amount of error diffused in a hybrid screening system. An image context error computer receives a pixel classification and an error value. Upon receiving these data, a set of shift registers supplies a fractional portion of the error value to an error diffusion circuit. A bypass thresholder receives screened video and applies simple thresholding. In parallel with the simple thresholding, an error diffuser receives screened video and applies error diffusion. The results of the two processes are output to a multiplexer which outputs one based on the pixel classification.

摘要： A high addressable multibit screening device and method for use in a PDL interpreter environment achieve improved printing resolution and quality. A PDL interpreter receives a PDL document from a host source, which identifies one or more objects that can be fully toned (black) or partially toned (line art or images). Each of these objects can be processed differently. Fully toned objects are processed within the interpreter and directly output in a predetermined output. Partially toned objects are sent to a high addressable screening module within the interpreter for processing prior to outputting in a desired output format. The high addressable screening module screens the partially toned objects to obtain multibit screened data for output. This can be achieved by converting an array of single threshold values to an array of three or more sub-threshold values in a way that preserves the pattern specified by the original threshold array (one bit per pixel image), but improves the quality of the rendered image relative to the quality of a one bit per pixel (per colorant) image. The partially toned data is then output with the fully toned objects for subsequent printing. This achieves an increase in available tints and spatial frequency for a given halftone pattern while reducing memory requirements.
摘要翻译：用于PDL解释器环境的高可寻址多位屏蔽设备和方法可实现改进的打印分辨率和质量。 PDL解释器从主机源接收PDL文档，其标识可以被完全调色（黑色）或部分调色（线条画或图像）的一个或多个对象。可以对这些对象中的每一个进行不同的处理。完全调色的物体在解释器内处理，并直接输出到预定的输出。将部分色调对象发送到解释器内的高可寻址筛选模块，以便在以期望的输出格式输出之前进行处理。高可寻址屏蔽模块屏幕部分调色对象以获得多位屏蔽数据进行输出。这可以通过将保持由原始阈值阵列指定的模式（每像素图像一个位）的方式将单个阈值的阵列转换为三个或更多个子阈值的阵列来实现，但是提高了渲染图像相对于每像素一个像素（每个着色剂）图像的质量。然后用完全调色的物体输出部分色调的数据以供后续打印。这实现了给定半色调图案的可用色调和空间频率的增加，同时减少了存储器需求。
