Abstract:
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; in response to new video information that includes an increase in size for a graphics item that includes a graphics window for output on the display device, where the new video information will lead to a new aggregate luminance for the display device that is greater than the initial aggregate luminance, altering the new video information, which includes altering video information for at least a portion of the graphics item that includes a central white portion of the graphics window after the increase in size, to produce altered video information that contributes to a reduced aggregate luminance for the display device that is less than the new 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.
