  • Method for performing duplex copying
    Patent number: 7619780
    Abstract: A method for performing duplex copying of a document having a first side with a first image and a second side with a second image includes scanning only the first side of the document under a first imaging condition to retrieve first information relating to each of the first image and the second image; scanning only the first side of the document under a second imaging condition to retrieve second information relating to each of the first image and the second image; determining from the first information and the second information contents of the first image on the first side of the document; and determining from the first information and the second information contents of the second image on the second side of the document.
    Type: Grant

  • Method for reducing show-through in a scanned duplexed document
    Patent number: 7620360
    Abstract: A method for processing a duplexed document having a first side with a first image and a second side with a second image includes scanning only the first side of the duplexed document under a first imaging condition to retrieve first information relating to each of the first image and show-through contribution of the second image; scanning only the first side of the duplexed document under a second imaging condition to retrieve second information relating to each of the first image and show-through contribution of the second image; and comparing the first information and the second information to reduce an amount of the show-through contribution.

  • Fast color interpolation
    Publication number: 20070070366
    Abstract: A method of performing color conversion to convert a set of input color values to color values in an output color space includes representing an output color in the output color space as a geometric lattice having a plurality of lattice points, each of the plurality of lattice points having an address defined by a particular set of input color values; using a set of input color values with respect to the geometric lattice to determine a set of lattice points that neighbor a point corresponding to the set of input color values to be interpolated; choosing a random number; and utilizing the random number to select a first lattice point of the set of lattice points to provide as a pseudo-interpolated result of the color conversion.

  • Method for processing a duplexed document
    Publication number: 20060263125
    Abstract: A method for processing a duplexed document having a first side with a first image and a second side with a second image includes scanning only the first side of the document under a first imaging condition to retrieve first information relating to each of the first image and the second image; scanning only the first side of the document under a second imaging condition to retrieve second information relating to each of the first image and the second image; and determining from the first information and the second information a show-through contribution of the second image with respect to the first side of the duplexed document.
