    摘要: Methods and systems herein provide for color conversion in the real domain from an input color space to an output color space using a color conversion table that includes color values defined in the output color space corresponding to color values in the input color space, a table of scaling factors, and a conversion engine operable to group the real domain image data into blocks of pixels. The conversion engine, for each block of pixels, converts a color value in the block of pixels from the input color space to the output color space according to the color conversion table, computes differences between the color value and color values of pixels in the block, scales the computed differences according to the table of scaling factors, and adds the scaled differences to the converted color values to convert the pixel color values to the output color space.

    摘要: The management of color presented at end point devices such as a display or printer is based on the implementation of a Color Management Resource (herein also CMR). A CMR is an architected resource stored accessibly to a print server or other processor that is used to carry all of the color management information required to render a print file, document, page, or data object. The invention here described is particularly focused on a color conversion type of CMR and defines a new type here called a Link Color Conversion CMR. In particular, a unique descriptor is tied to each input and output color conversion rule. A linked color conversion rule, created by combining the input and output color conversion, is created. The linked color conversion structure contains three parts—the descriptor of the input color conversion rule, the descriptor of the output color conversion rule, and the combined color conversion rule. By comparing the descriptors, it is possible to very rapidly identify a previously-existing linked color conversion that combines the input and output conversions.

    摘要: Provided are a method, system, and article of manufacture for converting image data in an input color space to an output color space in a transform domain. An input block of coefficients in an input color space is generated, wherein the input block includes a first type coefficient and a plurality of second type coefficients. The first type coefficient in the input block is converted to an output value in an output color space. The output value is used to determine a scaling factor for the second type coefficients. The scaling factor is applied to the second type coefficients to determine second type coefficients in the output color space. A component output block of coefficients in the output color space is formed from the output value for the first type coefficient and the determined second type coefficients in the output color space.

    摘要: Methods and systems herein provide for color conversion. Such color conversion includes a method of optimizing gray component replacement in a color image that includes receiving a color image from an input imaging device (e.g., a digital camera, scanner, etc), determining a color gamut of an output imaging device, such as a printer, and generating a CIELab to CMY numerical model to convert the color image to a color space within the color gamut of the output imaging device. The method also includes generating a CMYK to CIELab numerical conversion model, removing a portion of CMY color values generated from the CIELab to CMY numerical conversion model, and replacing the removed portion of the CMY color values with black color values. The method also includes optimizing CMYK color values via a multidimensional optimization using the CMYK to CIELab numerical model.

    摘要: Methods and systems herein provide for calibrating for a plurality of different paper types. In one embodiment, a system for calibrating a printer includes a measurement module operable to detect colors printed on a first tangible medium by the printer and convert the detected colors to a detected color characterization. The system also includes a storage module operable to store a calibration file. The calibration file includes color characterizations of a plurality of different tangible mediums and each color characterization includes color measurements for one of the plurality of different tangible mediums obtained from the printer via the measurement module when the printer is calibrated. The system also includes a calibration module operable to compare the detected color characterization to at least two color characterizations of the calibration file and determine an adjustment to an output color scheme of the printer based on the comparison to calibrate the printer.
