Abstract: The present invention is a method and apparatus for detecting the presence of image regions requiring compact dot growth control and controlling the dot growth of such regions when rendered on a printing system. The invention operates to recognize those pixels within a bitmap image that are appropriate for alteration, using a template-based approach, and then alters the exposure pulse of identified pixels during imaging so as to assure a more stable output by a xerographic development system.

Abstract: PROBLEM TO BE SOLVED: To improve the positioning precision of a color layer by retrieving a pixel from a contone (continuous tone) picture stored in a pictured buffer and composing this to one pixel value to generate a warping pixel so as to correct distortion at the beam scanning orbit of an output scanner. SOLUTION: The picture buffer 52 stores all the tags corresponding to some scanning lines of the contone picture together with the scanning line. An interpolation coefficient generator 54 generates an interpolation coefficient identifying a pixel in contone picture data 40 to be used for generating each warping pixel in a warping picture. The ideal pixel grid of a desirable orbit indicates where each pixel in the contone picture 40 is to be moved in order to be a desirable beam scanning orbit. At the time of stepping along the beam scanning orbit of ROS at regular intervals at a pixel position, the outputting position of each warping pixel concerning the ideal pixel is identified.

Abstract: PROBLEM TO BE SOLVED: To enhance the spatial arrangement accuracy of transition of the fringe part in the display image of an optical display system having a photosensitive recording medium. SOLUTION: The imaging apparatus 10 comprises an input 12 receiving a pixel signal representative of an input image, and a buffer 16 for storing received pixels. The imaging apparatus further comprises a processor 20 for processing the signal and directing a signal to an LED array bar 38 generating a latent image by exposing the areas of a photosensitive body selectively. The processor 20 controls exposure of the photosensitive body by varying exposure of a selected pixel based on the neighboring pixels. Input data of a digital image is scanned until specified conditions are reached and an altered exposure value is allotted to the input data based on the degree of proximity to the specified conditions.

Abstract: PROBLEM TO BE SOLVED: To more preferably segment scanned image data that can more accurately identify a background and text data within the scanned image data. SOLUTION: A method for processing scanned data indicative of a document image includes: segmenting the scanned data into background and foreground layers; displaying the scanned data containing data of foreground layer candidates on a plurality of windows, each of the plurality of windows including a selected region identifiable as contiguous to background layer data; extracting from the plurality of windows an object including text, graphical and pictorial objects; and classifying the objects on the basis of each object having a predetermined contrast level with the object periphery, thereby segmenting data for achieving high compression ratios with improved reconstruction image quality.

Abstract: PROBLEM TO BE SOLVED: To obtain a filter approximated to a circular symmetric descreening filter, in which approximation to a desired circular symmetric shape can be attained, even though processing power smaller than that requested for the execution thereof is demanded, in a non-separable circular symmetric descreening filter. SOLUTION: Two separate filters LPP and HPP are designed (designed or produced) to obtain a filter approximating the non-separable circular symmetric descreening filter. The low pass filter LPP is overlapped with the high pass filter and subtracted, whereby a response close to a circular symmetric response, obtained by the currently used non-separable circular symmetric descreening filter, is obtained.

Abstract: PROBLEM TO BE SOLVED: To optimize run cost for a multi-engine printing system.
SOLUTION: This method is a method for scheduling at least one print job for a plurality of printers. A job length for at least the one print job is determined. A sequence of printing by the plurality of printers is scheduled from the job length such that a subset of the available plurality of printers is cycled up. When the job length is less than at least one predetermined threshold, at least one print job with the subset of the available printers is printed.

Abstract: PROBLEM TO BE SOLVED: To calibrate colors of photosensors so as to correct color crosstalks among the photosensors in a color input scanner. SOLUTION: A photosensitive apparatus 100 includes a first photosensor 102R, which is sensitive to a first color (red) and a second photosensor 102G which is sensitive to a second color (green). The first photosensor and the second photosensor are exposed to the first color, and a test signal is derived from the first photosensor and the second photosensor. The first photosensor and the second photosensor are exposed to the second color, and a test signal is derived from the first photosensor and the second photosensor. A cross-color correction factor is derived from both the test signals. The cross-color correction factor is used in processing signals outputted from the first photosensor and the second photosensor, when an image is being recorded. COPYRIGHT: (C)2007,JPO&INPIT
