摘要:
Conversion of color data values from a rectangular coordinate system such as CIELab to a cylindrical coordinate system such as CIELCh using two one-dimensional look-up tables, one each for the C value and the h value. The one-dimensional look-up tables are accessed by defining a new variable γ as the absolute value of the ratio of b and a.
摘要:
The present invention comprises a method, for use in a color management system executing in a computer system, for generating at runtime, using device profile information, a look-up table for conversion of color data from one color space to another, the method comprising assigning a weight to each of table size, speed and accuracy factors, determining, for plural table sizes, corresponding speed and accuracy scores using the color management system, determining, for each of the plural table sizes, an aggregate of weighted scores corresponding to table size and speed and accuracy, selecting one of the plural table sizes using the aggregate of each of the plural table sizes, and generating a look-up table having the selected one of the plural table sizes.
