Abstract: Mapping of full color images to two-highlight color images which provides excellent results for both pictorial image and presentation graphics applications is described. Shades and tints for each hue in the original full color image are mapped to a corresponding triangle of colors in a tetrahedral of possible colors defined by the two highlight colors. The apex of the triangle of colors is varied within the tetrahedral of possible colors according to hue. Differentiations in the result colors for the fully saturated cases is provided while preserving the relative saturation and lightness behavior. The triangle of colors maps to a first triangle bordering one side of the tetrahedral, the first triangle corresponding to a first one of the highlight colors or a second triangle bordering another side of the tetrahedral, the second triangle corresponding to a second one of the highlight colors when the hue of the original colors matches one of the highlight hues. Mappings may be provided for printers using arbitrary highlight colors. The mappings preserve information important to the viewer without discarding dimensions of the color space. Different information can be preserved depending upon the particular application.

Abstract: An image rendering system includes a digital front end to electronically analyze image data to generate geometry dependent image content information. A print engine, operatively connected to the digital front end, renders the image data. A print engine controller, operatively connected to the digital front end and the print engine, controls various parameters of the print engine. The digital front end transmits the image content information to the print engine controller. The print engine controller adjusts a parameter of the print engine based on the transmitted image content information. The transmitted image content information may be coverage information, reload information, and/or toner pile height information. The parameter of the print engine adjusted based upon the transmitted image content information may be fuser temperature and/or process speed of a developer housing and/or flow rate of toner into a developer housing.

Abstract: A method and systems for calibrating a document scanner are provided. The scanner calibration method includes providing a geometrically operative black absorption device having a structural geometry that is capable of receiving light and limiting propagation of the received light, where the black calibration target has a total light reflectance of less than one percent. The method further includes powering on a light source of a document scanner to provide light toward the black absorption device, where the light source generates a noise signal when providing the light. The method further includes detecting, by a sensor of the document scanner, light reflected from the black absorption device and generating calibration signals based on the reflected light and the noise signal.
