Method and apparatus for providing independent gamut remapping for multiple screen subsections

An apparatus comprising:

• logic operative to generate, independently from operating system control, different screen subsections of a screen image using independent gamut remapping configurations to generate an output image in a target gamut space;
• and
• memory that stores at least first and second gamut remapping coefficients for different gamut remapping configurations, the memory operatively coupled to the logic, and wherein the logic is operative to generate different screen subsections of a screen image having independent gamut remapping configurations by selecting from the at least first and second gamut remapping coefficients to perform gamut remapping for a first screen subsection using the first set of gamut remapping coefficients and perform gamut remapping on a second screen subsection using the second set of gamut remapping coefficients.

A non-transitory computer readable medium that comprises executable instructions that when executed by one or more processors causes the one or more processors to:

• generate, independent of operating system control, different screen subsections of a screen image using independent gamut remapping configurations to generate an output image in a target gamut space of a display;
• select from at least first and second gamut remapping coefficients to perform gamut remapping for a first window using the first set of gamut remapping coefficients and perform gamut remapping on a second window using the second set of gamut remapping coefficients;
• and provide the output image for display on a display.
