Power efficient display color processing for static regions on screen

An apparatus for display processing, comprising:

• a memory;
• and
• a processor coupled to the memory and, based on information stored in the memory, the processor is configured to:
• obtain a first indication of an aggregated second region for each frame in a set of frames, wherein each frame in the set of frames includes a first region that will remain static, wherein the second region for each frame in the set of frames differs for each frame in the set of frames, and wherein the set of frames is subsequent to a first frame that includes the first region;
• blend, based on the first frame, the second region for each frame in the set of frames;
• and
• perform post-processing on the blended second region for each frame in the set of frames.

A method of display processing, comprising:

• obtaining a first indication that a first region of a first frame will remain static;
• aggregating, based on the first indication, a second region for each frame in a set of frames that is subsequent to the first frame, wherein each frame in the set of frames includes the first region that will remain static, and wherein the second region for each frame in the set of frames differs for each frame in the set of frames;
• and
• outputting a second indication of the aggregated second region for each frame in the set of frames.
