Luminance suppression power conservation
First Claim
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.

Abstract
Described herein are systems and methods that reduce power consumption for an electronics device including a display. The systems and methods alter video information in a display area and reduce power for a display device when a graphics item is enlarged and the enlargement threatens to increase perceived luminance for the graphics item or increase aggregate luminance for the display area. Altering the video information reduces the luminance of video information in at least the graphics item when enlarged. This may offset perceived luminance gained by human visual processing when an item increases in size. If the graphics item is smaller than the display area after enlargement, then other video information in the display area may also be altered to conserve power.
