摘要： A method for processing black point compensation parameters for a color image to be printed so as to enhance image quality of the color image is provided. The method includes analyzing image content of a received color image to identify one or more performance attributes to be considered during a black point compensation parameters processing procedure, the performance attributes estimate an effect of the black point compensation parameters on the image quality of the received color image; selecting, based on the identified performance attributes, a black point compensation (BPC) algorithm to be used during the processing procedure; deriving a model using the identified performance attribute that is configured to estimate relationships between the black point compensation parameters and the identified performance attribute; maximizing the performance attribute of the derived model so as to process the BPC parameters for the color image; and using the processed black point compensation parameters to construct output device profiles.

摘要： A methodology is disclosed to achieve adaptive illumination independent matching of out-of-gamut spot colors. In one embodiment, the methodology includes an iterative process to determine a variety device specific recipes for out-of-gamut spot colors across different illumination spectra and gamut mapping techniques, and then automatically choosing and/or recommending the optimal recipe and gamut mapping technique that provides the lowest color dispersion across a variety of illuminants under consideration.

摘要： What is disclosed is a system and method for merit-based gamut mapping. In one embodiment, color points are clustered in regions of interest within a color space. Each cluster is associated with a gamut mapping function and a merit function. Mapping parameters of each gamut mapping function are iteratively varied to optimize the values based on the merit function value. An optimized gamut mapping function results. Optimized gamut mapping functions of adjacent clusters are blended together by blending the value of the gamut mapping function for a point of a cluster with a value produced by the gamut mapping function of an adjacent cluster for that color point. The composite gamut mapping function contains the optimized gamut mapping functions of all clusters is then output for use in mapping points within those clusters to points within the target gamut. The composite gamut mapping function exploits local advantages of each cluster.
