Patent ID: 8502473

Claim:
A method of controlling a light for a component of an electronic device, comprising: defining a plurality of brightness evaluation zones within a scale of brightness levels for the device; defining an activation status for the light for each brightness evaluation zone of the plurality of brightness evaluation zones; and evaluating detected ambient light around the device against a progression of zones in the plurality of brightness evaluation zones until the detected ambient light is in within one zone of the progression of zones, then if the activation status for the one zone indicates that the light is not to be activated, then deactivating the light; if the activation status for the light for the one zone indicates that the light is to be activated, then determining whether a further zone of the plurality of zones exists in the progression, and if the further zone exists then the activation status is set to the activation status of the further zone and the detected ambient light is re-evaluated to determine if it is or is not within the range of further zone, otherwise activating the light.
