  • Patent number: 9710943
    Abstract: Disclosed is a method of rendering a plurality of graphical objects. The method generates a region graph using at least a plurality of intersection points of the graphical objects. The intersection points identify disjoint regions each representing a particular combination of the graphical objects, in which the region graph has at least one region graph link, and defines a relationship between the regions. A contributing level and an activating direction are assigned to at least one of the region graph links, the level and the activation direction defining an appearance of the region associated with said region graph link. The method then renders the plurality of graphical objects using the assigned contributing level and activating direction of the region graph links by traversing the region graph to determine at least one contributing level for each region in the region graph using the assigned contributing level and the activating direction.

  • Patent number: 9224362
    Abstract: Many imaging scenarios involve an achromatic image (e.g., a panchromatic image or a near-infrared image) and one or more concurrently captured monochromatic images (e.g., RGB images captured through a Bayer filter array), and the compositing of these images through de-mosaicing and/or pan-sharpening to generate a high-resolution color image. However, in many such scenarios, the monochromatic images may exhibit distortion of edge geometry, resulting in artifacts and/or color distortions near visual edges of the composite image. However, such distortions may be absent from the achromatic image, and edge geometry may be represented as an intensity gradient among respective neighborhoods of achromatic pixels. Presented herein are techniques for reducing such distortions in monochromatic images through iterative adjustment of monochromatic pixel intensity to reflect the gradients of the neighborhoods of the corresponding achromatic pixels.

  • Patent number: 8934140
    Abstract: A color gamut of image data is appropriately subjected to a smoothing processing to print an image of favorable color reproduction and gradation reproduction. Specifically, when an average lightness is equal to or lower than a blacking lightness, the object pixel is not subjected to the smoothing processing. This can conserve the signal value of the object pixel to prevent a pixel originally having a signal value higher than the blacking lightness from being converted by the gamut compression to a black point. In this manner, a pixel for which the object pixel has the average lightness equal to or lower than the blacking lightness is blacked and a pixel having a signal value higher than the blacking lightness is not compressed to the black point. The resultant image has no deteriorated gradation characteristic when being macroscopically observed.

    Abstract: A method for classifying a document (3) to be associated with at least one service (Si), including a step in which a scanner (1) having a processor (6) scans (E1) the document (3). The method also includes steps in which the processor (6): develops (E2) at least one structure (?j) representing the document (3), determines (E3) for each service (Si) at least one similitude value (?ij) between the structure (?j) representing the document and a reference structure (Rij) of the same kind and representing the service (Si), deduces (E4) from the similitude value (?ij) the service (Si) with which the document (3) is to be associated, and processes (E5) the document (3) according to the service (Si) thus associated. The invention also relates to a scanner for implementing the method.

  • Patent number: 8736930
    Abstract: Methods and systems receive a print job and determine whether the print job specifies one or more extended gamut color marking materials. The extended gamut color marking materials comprise marking materials having colorants other than standard colorants. The standard colorants consist of cyan, magenta, yellow, black (CMYK). When the print job does not specify one or more of the extended gamut color marking materials, the methods and systems determine whether the print job will perform better with one or more of the extended gamut colorants in addition to the standard colorants. The methods and systems print the print job use the extended gamut colorant(s) and the standard colorants when the print job specifies the extended gamut color marking material, and when the print job will perform better with one or more of the print system's extended gamut colorants in addition to the standard colorants.

  • Patent number: 8693048
    Abstract: Methods and apparatus for optimizing the phase lock loop circuitry of sub-pixel clock generators for situations where frequent switching between different system printing speeds, and hence clock frequencies are required. An optimizing circuit is associated with a sub-pixel clock generator for clamping an input voltage to a voltage controlled oscillator controlling clock frequency between a desired range. The clamping circuitry comprises a comparator for detecting when the voltage has moved out of the desired range and then charges or discharges a loop filter circuit controlling the input voltage to the VCO to keep the input voltage within the desired range.

  • Patent number: 8687236
    Abstract: A method and apparatus as provided for determining, for an ink to be deposited on a substrate by a halftone inkjet printing process, a nominal coverage value (the ‘ink restriction value’), that corresponds to an amount of ink sufficient to fully cover the area of the substrate to be printed. This determination is effected by measuring the reflectance of the printed substrate for a range of nominal coverage values, and then using an automatic processing arrangement to determine, from the change of measured reflectance with nominal coverage value, the nominal coverage value at which continuous tone behavior commences.

  • Patent number: 8659791
    Abstract: In a prior art, since the wavelengths of R, G, and B LEDs serving as the light sources of a CIS scanner vary, read colors vary between individual scanners. Since the behavior of metamerism also changes due to the same reason, measures against the metamerism are hard to take. To solve this problem, a color patch is irradiated with light from an LED, and its spectral reflectivity is measured using a spectroreflectometer, thereby estimating the emission wavelength of the light source LED. A signal change characteristic representing the relationship to the output signals of three LEDs obtained from the spectral reflectivity of the patch is stored in a memory. In actual image reading, color correction is performed based on the signal change characteristic stored in the memory.
