Systems and methods for improving image quality of image data to be rendered may be provided using multiple mask MRC files. Such a method may involve processing a first binary bit map of image data to generate a processed binary bit map, assigning an edge tag to at least one pixel in the processed binary bit map, and assigning a gray/color value to at least one pixel in the processed binary bit map based on values of corresponding pixels in the first binary bit map. A system may include a processor that performs such processing and assigning, an image data source that supplies image data of an original image, and an image rendering device that provides a rendered image of the original image based on the at least one assigned edge tag and the at least one assigned gray/color value.

Systems and methods for improved line edge quality

The invention generates a page description language compliant data stream, that has been pre-designed and pre-processed to create unique and predictable page element ordering, overlay layout, and for splitting large page elements into multiple independent elements. In this way, multiple processors can be used to render the document without merging the data stream.

Systems and methods for rapid processing of raster intensive color documents

The automatic relocation of images in an electronic reprographic system includes scanning documents comprising a print job, converting the documents to electroniic manipulatable images, storing the images for print generation and shifting the locations of the scanned images to obtain a desired output. The location shifting can provide a one-sided cover page for a print job having a duplex arrangement, reordering to form duplex output from simplex input and joinder of a plurality of sets of documents without gap generation therebetween.

Image relocation in an electronic reprographic system

A realtime control process for an electronic reprographic system in which background and job requests are dynamically partitioned into unique combinations of virtual machines for carrying out each request, with each virtual machine having certain system services to carry out the function provided by the virtual machine.

Control for electronic image processing systems

A state controller for an electronic reprographic system for controlling system operations when processing requests in which the system has a plurality of hardware and software system components providing discrete services for processing requests and maintaining operation of the system, and job programming means including a display screen for inputting requests, including: a state holder for monitoring the current operating state of the system components; plural discrete job processing virtual machines with each of the virtual machines having at least one service associated with it for implementing the virtual machine; each of the services having at least one of the system components for carrying out the service; and a scheduler for managing resources of and setting priorities for the virtual machines to process the requests in an efficient manner, the scheduler being adapted to cause memory from a first one of the virtual machines to be distributed to a second one of the virtual machines when the second one of the virtual machines requests more memory than is normally allocated to it.

System state controller for electronic image processing systems

An electronic printing system having the capability of producing cover sheets for an output document set, including the ability to allow an operator to select the desired features of the cover sheets. Moreover, the system has a scanner for scanning an original document set, thereby producing an electronic representation of the set of original documents. Subsequently, the system is capable of automatically reordering the electronic images in a manner suitable to produce front and/or back cover sheets in accordance with the features previously selected. Finally, the output section of the system generates printed output of the reordered electronic images, thereby producing a completed document, including covers.

Generation of document covers in an electronic reprographic system using

An electronic reprographic system with a scanner for scanning the document pages of a job and converting the document images scanned to an array of binary pixels. The ability to convert a high resolution array of binary pixels representing the scanned image to a lower resolution, gray version for display on a screen and further eliminate effects of contouring and moire on the displayed image.

Elimination of contouring on displayed gray level images

In a system for detecting and signaling the approximate size of a set, stack or job of document sheets, especially for a recirculating type automatic document feeder with a document set stacking and feeding tray for a copier or other document imaging system, in which an electromechanical set separator system provides rough initial stack height and therefore set size or document number estimation signals from the position of the set separator arm on the stack, and in which there is also a counter for counting the number of document sheets fed out from the tray; the advance estimation of the number of documents to be fed to be imaged is significantly improved by dynamically comparing the count of the number of document sheets fed out from the tray at and with the transition in the set size estimation signal from the set separator system.
