1. A method comprising:

  • determining, by at least one processor, a compressed pixel intensity range for a plurality of pixel intensity levels of a display device based at least in part on a target power scaling value, wherein the target power scaling value is associated with a target power consumption of the display device to display an image;

    determining, by the at least one processor, a set of initial scaled pixel intensity levels for the plurality of pixel intensity levels based at least in part on the compressed pixel intensity range;

    determining, by the at least one processor, an estimated power consumption value, wherein the estimated power consumption value is associated with an estimated power consumption of the display device to display the image according to the set of initial scaled pixel intensity levels;

    determining, by the at least one processor, a set of scaled pixel intensity levels based at least in part on a ratio of the target power scaling value to the estimated power consumption value; and

    scaling a pixel intensity of each of a plurality of pixels of the display device from one of the plurality of pixel intensity levels to a corresponding scaled pixel intensity level of the set of scaled pixel intensity levels to display, by the display device, the image according to the set of scaled pixel intensity levels.
