1. A method for reducing power consumed by an electronics device that includes a display device, the method comprising:

  • displaying initial video information that contributes to an initial aggregate luminance output by the display device;

    determining the initial aggregate luminance output by the display device as the display device displays the initial video information;

    in response to an indication for output of new video information on the display device, determining a new aggregate luminance to be output by the display device if the display device were to display the new video information;

    determining whether the new aggregate luminance for the display device is greater than the initial aggregate luminance;

    altering the new video information so as to produce altered video information that contributes to a reduced aggregate luminance for the display device that is less than or equal to the initial aggregate luminance when the new aggregate luminance for the display device is greater than the initial aggregate luminance; and

    displaying the altered video information, wherein the display device consumes less power when displaying the altered video information than would be consumed for display of the new video information.
