SYSTEM AND METHOD FOR ILLUMINATING A COMPONENT OF AN ELECTRONIC DEVICE
First Claim
1. 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, thenif 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, andif 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.

Abstract
The disclosure describes a system and method for controlling a light for a component of an electronic device. An embodiment uses brightness evaluation zones and progresses through one or more of the zones to determine whether and when to activate the light for given conditions of ambient light. In doing so, the embodiment sets a current brightness evaluation zone for the device and sets an activation status of the light level to an activation value associated with the current brightness evaluation zone. The embodiment compares an ambient light level for the device to the current brightness evaluation zone. Evaluation loops are provided to test and change the current brightness evaluation zone against the detected ambient light. The light may be a backlight.
