摘要： A printer driver operates a printer capable of multiple dot-placement geometries or resolutions and multiple inks per color channel. It maps a continuous-tone cyan pixel-component value to continuous-tone light- and dark-cyan values, which it separately halftones to respective binary pixel values that respectively indicate whether an associated pixel will receive light- and dark-cyan ink dots. It similarly generates binary values that respectively indicate whether an associated pixel will receive light- and dark-magenta ink dots. In performing the halftoning, the driver separately performs error diffusion through different interleaved sub-images of the image to be printed so that the error-diffusion process is performed for images whose pixel geometry is that for which the process was designed even though the overall image's pixel geometry is not. The result is a modular, scaleable architecture, in which designs for one ink per channel and/or one dot-placement geometry can be adapted with minimal design effort to multiple inks and dot-placement geometries.

摘要： A photocopier (10) scans a document and so modifies the resultant image as to embed in a resultant copy information that is visually imperceptible. To do so, it identifies regions (32, 33) that consist primarily of text-character parts. It embeds a message bitstream by selectively darkening the text pixels in such regions in accordance with the values of successive bits in the bitstream.

摘要： A scanner (12) of a photocopier system scans a document and generates output image signals that an image-processing circuit (14) processes in such a manner as to enhance text-region legibility, and a laser printer (16) generates the output copy in accordance with the resultant image. The image-processing circuitry (14) identifies dark, low-saturation pixels in the input image whose gradients are low but that border high-gradient pixels, and it sets these pixels to the blackest values, thus emphasizing text edges. With the remaining pixels, it reduces bright-region contrast, and this tends to suppress the visibility of text that has “bled through” from the document's reverse side or from documents disposed behind it.

摘要： A system for detecting image black and white points for a digital image. The system includes image partitioning routines for partitioning a digital image into image blocks, a pixel counter for determining whether the image block contains sufficient black and white pixels to classify the block as having relatively black text on a relatively white background, block validity testing routines for determining whether the selected image block is valid by determining whether the number of relatively black pixels for the selected image block is greater than a predetermined black threshold and whether the number of relatively white pixels for the selected image block is greater than a predetermined white threshold, and pixel clustering routines for arranging the relatively black pixels of a valid block into black clusters and the relatively white pixels of a valid block into white clusters and for assigning one of the black cluster centroids based on a first predetermined set of rules as the image black point and one of the white cluster centroids based on a second predetermined set of rules as the image white point.

摘要： Disclosed are embodiments of systems and methods for identifying features using color information in an image. The image may be formed from one or more display images comprising color information and features or feature components. Because color information may be used to identify features, more than one feature or feature component may be displayed in a display image. Because a plurality of features may be identified in a calibration image, an image system, such as a projector-camera system, can reduce the number of display images needed to calibrate the system.

摘要： Smart printing/copying techniques for controlling the printing/copying and editing of a document based on document-descriptive and control information embedded in the printed output. These “smart” printing/copying techniques and controls allow a document user to control printing/copying costs by making tradeoffs with respect to quality and speed based on the embedded data. Such costs may be controlled, for example, by initially printing low cost (low quality, high speed) pages for distribution, while giving subsequent recipients of the document the option of making high quality (higher cost, possibly slower) copies of any or all of the pages in the document, if desired. With these features, a user is able to obtain high quality copies from low quality originals. The techniques of the present invention also allow a recipient to edit page content prior to reprinting, without loss of print output quality.

摘要： A fast text/graphics resolution improvement algorithm is based on boundary parameterization and uses chain-code table look-up. Given an input representation containing text/graphics objects, the boundary of each object is traced, parameterized, smoothed, and subsequently rendered. Instructions for the critical operations are stored in one or more pre-computed look-up tables (LUTs) which is/are accessed during on-line operation, resulting in an algorithm that is fast and computationally inexpensive with low memory requirements. A very flexible framework is presented which can be utilized in a variety of applications requiring resolution improvement.
