  • Patent number: 10140945
    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.
