Abstract
Methods and devices are provided for controlling the brightness of a display for an electronic device based on ambient light conditions. In one embodiment, an electronic device may employ one or more brightness adjustment profiles that define response rates for changing brightness levels based on ambient light levels. The response rates may vary depending on the magnitude and/or direction of change in the ambient light levels. In certain embodiments, the response rates may be designed to approximate the physical response of the human vision system. Further, in certain embodiments, noise reduction techniques may be employed by adjusting the response rates based on the magnitude of the change in the ambient light level and/or based on whether the display is operating at steady state or executing a brightness adjustment.
