Color preservation for spatially varying power conservation

摘要

Described herein are systems and methods that reduce power consumption for an electronics device that includes a display device. The systems and methods identify characteristic color video information for a graphics component that allows a person to visually locate the graphics component in a display area for the display device. Video information in the display area other than the characteristic color video information is then altered to conserve power. Preserving the characteristic color video information for the graphics component maintains a person's ability to locate the graphics component at a later time, even though other portions of the display area have been altered and potentially visually degraded to conserver power.
