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:
- increasing a size of a graphics item to create a larger graphics item;
in response to increasing the size of the graphics item, altering, if a portion of the graphics item includes a color that increases a brightness, video information for at least a portion of the larger graphics item to produce an altered larger graphics item with a reduced luminance; and
displaying the larger graphics item based on the altered video information without altering video information of other graphics items displayed on the display device,wherein the display device consumes less power when displaying the larger graphics item based on the altered video information than would be consumed for the larger graphics item without the video information alteration.

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.

12. A non-transitory computer readable medium including instructions executable by a processor for reducing power consumed by an electronics device that includes a display device, the instructions specifying a method comprising:
-
increasing a size of a graphics item to create a larger graphics item; in response to increasing the size of the graphics item, altering, if a portion of the graphics item includes a color that increases a brightness, video information for at least a portion of the larger graphics item to produce the larger graphics item that includes a reduced luminance; and displaying the larger graphics item based on the altered video information without altering video information of other graphics items displayed on the display device, wherein the display device consumes less power when displaying the larger graphics item based on the altered video information than would be consumed for the larger graphics item without the video information alteration. - View Dependent Claims (13)

14. A system for reducing power consumed by an electronics device that includes a display device, the system comprising:
-
at least one processor configured to; determine, when a size of a graphics item is increased to create a larger graphics item, aggregate luminance for a display area of the display device; and alter, in response to increasing a size of a portion of the graphics item having a color that increases a brightness, video information of the larger graphics item to produce altered video information with a reduced luminance for the larger graphics item or a reduced aggregate luminance for the display device, without altering video information of other graphics items displayed on the display device, wherein the display device consumes less power when displaying the larger graphics item based on the altered video information than would be consumed without the video information alteration. - View Dependent Claims (15, 16, 17, 18)
