摘要： The present invention relates to a color management method for the conversion of internal color appearance space color values to CMYK device values, by interpolating CMY values from a plurality of CMY to color appearance space lookup tables, wherein each CMY table is associated with a specific value of K. A target internal color value is received and the relative purity of that color is calculated in the CMY space. Next, a black generation value is calculated using the relative purity of the target color. Finally, one of the plurality of CMY lookup tables is selected based on the black generation value, and a CMYK value is provided based on an interpolation from the selected lookup table. In this way, the present invention is able to control the output K value in a color appearance space to CMYK conversion. Accordingly, colors across a wide relative purity range, including natural images, can be reproduced with better accuracy and higher quality.

摘要： Color measurements are generated from transform-based device profiles for use in a measurement-based color management system. The color measurements are generated by providing device-dependent color samples to a transform-based color management module and converting them to the profile connection space with the device's transform-based profile. Color measurements are then generated from the transform-based color management module by applying an identity profile in place of a destination device profile. In addition, measurement data can be extracted directly from either the tone reproduction curve/matrix or n-dimensional lookup table transforms contained within a transform-based device profile. In addition, a method and apparatus for generating transform-based color profiles by a measurement-based Color Management System (CMS) is provided. The measurement-based CMS generates the transform-based profile wherein the measurement-based color system is parameterized by color data and procedures. The CMS may use a reference Profile Connection Space (PCS) loaded from a measurement profile, thus enabling user configuration of the generation process. The reference PCS may also be set to include a gamut that is appropriate for an eventual color-output device. In addition, a Gamut Mapping Model (GMM) used in the generation process is user-selectable as well as a Device Model (DM). The DM may also be supplied as a pluggable module. The CMS also features user-selectable mapping from an International Color Consortium (ICC) intent to a PCS profile and to a DM. The features of the CMS may be used in an application, stand-alone profiling tool or in an operating system utility.

摘要： A color conversion for color devices having a large number of input channels is performed using a collection (Sl-Si) of look-up tables that stratify an n-dimensional color space into sets of lower dimensional subspaces. A color management module (600) using the collection for colo conversion may determine if a color conversion is for a color value that falls within a gap. In one interpolation process, a hypercube (1200) enclosing the input value is generated. An initial barycentric projection performs the interpolation from a selected vertex of the hypercube through the input value onto a boundary of the unit hypercube. If the projection satisfies one of the boundary conditions, an interpolated value is calculated. If the initial projection does not satisfy a boundary condition, an intermediate value is generated and successive barycentric projections are performed until a projection satisfies one of the boundary conditions. A final interpolated value is then generated.
