Patent Number Title Of Patent Date Issued
7382379 Arrangement for mapping colors between imaging systems and method thereof June 3, 2008
A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Col
7177047 Gamut-preserving color imaging February 13, 2007
A color imaging technique includes setting a target value in a device-independent first color space and mapping the target value to a substantially complete point set in a second color space. The point set may include a plurality of points, each of which define substantially the same
6650446 Colorimetric characterization of scanned media using spectral scanner and media models November 18, 2003
Modeling spectral characteristics of an image acquisition device. In one implementation, a computer system predicts the spectral reflectance or transmittance of a sample scanned by an image acquisition device, such as a graphics arts scanner, by modeling the device. The sample is scanned
6633408 Spectral modeling of photographic printing based on dye concentration October 14, 2003
Predicting a reflectance spectrum of a photographic print based on data from a scanned color negative. The technique uses dye concentration, providing a channel-independent basis for the spectral model. The spectral model includes three conceptual sections: scanner and film models, a
6362808 Arrangement for mapping colors between imaging systems and method therefor March 26, 2002
A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color
6232954 Arrangement for high-accuracy colorimetric characterization of display devices and method theref May 15, 2001
Arrangements and methods characterize the calorimetric response of a display device. These arrangements and methods use an analytic model selected based on the type of the display device to characterize the calorimetric response of the display device. A lookup table compensates for i
6088038 Arrangement for mapping colors between imaging systems and method therefor July 11, 2000
A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color
6072589 Arrangement for efficient characterization of printing devices and method therefor June 6, 2000
A method for characterizing a halftone printer uses a reduced number of test patches to simulate the printing characteristics over the printer's full range of realizable color combinations. The method involves obtaining a set of color values from each of a limited number of test patches.
5526140 Emulation of a halftone printed image on a continuous-tone device June 11, 1996
A system and method for representing a multi-color, halftone image on a multi-color, continuous-tone device can be configured to employ an approximation technique for determining areas of overlap regions produced by adjacent device spots in a printed halftone image based on a halftone
