Method and apparatus for improved color management

摘要

A method and apparatus for color matching during compositing. In one embodiment of the invention, a set of one or more un-color matched pixels are stored and associated with a first color profile. A fragment program is generated based on the first color profile and a second color profile associated with a display. During compositing of the set of un-color matched pixels, the fragment program is applied to the set of un-color matched pixels to match colors of those pixels with the display. The color matched pixels are written to the display. Other methods and apparatuses are also described.

1. A computer implemented method for color matching during compositing, comprising:
storing a set of one or more un-color matched pixels of at least one image, wherein the set of un-color matched pixels of the at least one image is associated with an image color profile, wherein the set of un-color matched pixels collectively form a first region and a second region to be positioned on a display, wherein the first region is associated with the image color profile, and the second region is associated with a color profile different than the image color profile; generating a first fragment program based on the image color profile and a display color profile, wherein the display color profile is associated with the display; applying the first generated fragment program to the set of un-color matched pixels of the first region to match colors of those pixels with the display during compositing of color matched pixels with a graphics processing unit; and writing the color matched pixels to the display.
