  • Patent number: 7227988
    Abstract: A method of generating a binary Sel plane for image compression is disclosed. The method first generates a 2 bit gray selector (GraySel). This 2 bit selector is then processed in a second stage to produce a binary Sel decision which minimizes the compression noise evident in the reconstructed image. The method used here to generate the 2 bit GraySel applies a set of prioritized rules over a small 3×3 window that is well suited for segmenting synthetic, PDL generated images that are typically free of scanner noise. The method not only marks the proper sense of the selector when it is known, but also include a 3rd state that indicates that the selector decision is weak or unknown. This weak decision can then be optimized in the second stage process based on strong edges information in the neighborhood.

  • Patent number: 7139442
    Abstract: A method and a system for separating an image signal into a set of image planes are disclosed. The system comprises a way to perform resolution conversion from low resolution to high resolution binary images either for synthetic or scanned imagery by using template matching with pattern replacement. More specifically, the invention applies resolution conversion to the selector plane of mixed raster content images. For selector planes in which edges are encoded (vs. region classification), template matching/pattern replacement works well, and does not affect halftoned regions, as they are not encoded in this image.

  • Patent number: 7062100
    Abstract: In an image-data processing system, as would be found in a digital copier or scanner, a relatively quick calculation is performed to estimate a compression ratio or compression time resulting from applying a compression algorithm to an image data set. If the estimated compression ratio or compression time is determined to be unfavorable, the system is advised not to apply the compression algorithm. The method can also be used to select a type of compression algorithm, such as CCITT G4 or JBIG2, according to the requirements of the larger system.

  • Patent number: 7050627
    Abstract: A system and method for generating achromatic components for output incorporate receiving input color data defined in a first color space. The received input color data is converted to intermediate color data defined in an intermediate color space. Typically the intermediate color space is defined only in terms of chromatic components. A black or achromatic component is then calculated. The black or achromatic color component is a function of both the input color data in the first color space and the intermediate color data in the intermediate color space. This black or achromatic color component is associated with the intermediate color data for further processing and output.

  • Patent number: 7009735
    Abstract: A method for performing black trapping and under print processing on image data from a raster image processing (RIP) frame buffer is provided. The image data includes pixel data according to a predetermined color space (e.g., RGB) and may include black rendering hints. If black rendering hints are not included, the method includes steps to determine if each pixel from the frame buffer is black or black with respect to predetermined thresholds. Three further embodiments of the method are provided in regard to CMY under print values for a black pixel when all pixels of a context window surrounding the black pixel are black. One embodiment provides no CMY under print. Another embodiment provides a predefined CMY under print. Still another embodiment provides an adaptive CMY under print based on the last saved CMY under print value.

  • Patent number: 6771392
    Abstract: A method for simulating high resolution printing by converting high resolution bits of a binary image to sub-pixel high addressable bits is presented. A first image is received having a first fast-scan resolution and a first slow-scan resolution. The first image is converted to a second image having a second fast-scan resolution and a second slow-scan resolution. The second fast-scan resolution of the second image is greater than the first fast-scan resolution of the first image. Also, the second slow-scan resolution of the second image is less than the first slow-scan resolution of the first image. In addition, a method of generating a high addressable halftone image from a high resolution binary image for marking on an image output terminal is presented. A high addressable halftone threshold array having a first high addressability value is converted to a balanced halftone threshold array having a first resolution in a fast-scan direction and the same first resolution in a slow-scan direction.

  • Patent number: 6608701
    Abstract: A compact rendering processor for processing image data including a multi-bit halftone region generates high addressability pixels. The compact rendering processor includes a tagging sub-processor operating on the image data to identify a target pixel and a neighboring pixel to determine a fill-order. The compact rendering processor also includes a rendering sub-processor that converts the target pixel into a high addressability pixel based upon the fill-order. Optionally, a diffusion sub-processor can be included to diffuse an error resulting from the conversion of the target pixel into a high addressability pixel to other pixels within the image data.
