Method and apparatus for improved color management

Abstract

A method and apparatus for color matching during compositing. Un-color matched pixels that form a window include a first region that includes un-color matched pixels and a second region that includes un-color matched pixels. The first region and the second region are associated with a first and second color profile respectively, which are different. During compositing of these un-color matched pixels, the un-color matched pixels of the first region are color matched based on the first color profile and a display color profile associated with the display, and the un-color matched pixels of the second region are color matched based on the second color profile and the display color profile. The color matched pixels are written to the display.
