Abstract
A method for controlling a display screen brightness level for an electronic device. In one embodiment, the electronic device determines a first ambient light level and associates the first ambient light level with a first priority weight value. The electronic device further determines a second ambient light level and associates the second ambient light level with a second priority weight value. A display controller within the electronic device sets the display screen brightness level based, at least in part, on the first ambient light level, the second ambient light level, and at least one of the first and second priority weight values.
