Abstract
A method, of operating a display of a computing system, includes: identifying a focused region and a non-focused region of an original image; transforming color values of pixels in the non-focused region from a full color gamut of the display to a power reduced color gamut; generating a remapped image by remapping the non-focused region of the original image with the transformed color values; and outputting the remapped image on the display with the full color gamut in the focused region and the power reduced color gamut in the non-focused region.
Claims10
A computing device for operating a display, the computing device comprising:
- a subcomponent configured to:
- identify a focused region and a non-focused region of an original image, wherein the non-focused region comprises elements in the original image with classification information based on a power policy of the computing device;
- transform bit-depth values of pixels in the non-focused region from an original bit depth of the original image to a lower bit depth;
- and
- generate a remapped image by remapping the non-focused region of the original image with the transformed bit-depth values;
- and
- the display coupled to the subcomponent and that displays the remapped image with the original bit depth in the focused region and the lower bit depth in the non-focused region.
