Abstract

A method of configuring one or more illumination states for illuminating at least two user interface devices of a mobile device, the method comprising assigning a first illumination state to first and second user interface devices, when intensity of ambient light is greater than a first threshold; assigning the first illumination state to the first interface device, and a second illumination state to the second interface device, when the intensity of the ambient light is between the first threshold and a second threshold; and assigning the second illumination state to the first and the second user interface devices, when the intensity of the ambient light is less than the second threshold.

Dependent claims

A method for controlling an illumination system for a mobile device, the method comprising:

measuring a first intensity of ambient light for the mobile device using a light sensing mechanism;
receiving first and second ambient light intensity threshold values from the user of said mobile device;
storing said first and second ambient light intensity threshold values in said mobile device;
comparing the first intensity with said first and second ambient light intensity threshold values;
adjusting illumination intensity of a first illuminating mechanism that illuminates a first user interface component of the mobile device, when the first intensity is not approximately equal to the first ambient light intensity threshold value;
adjusting illumination intensity of a second illuminating mechanism that illuminates a second user interface component of the mobile device, when the first intensity is not approximately equal to the second ambient light intensity threshold value;
establishing a stable illumination intensity state for the first and second illumination mechanism wherein a user defined predetermined range about each of the first and second thresholds is established by a first and second lower bound and a first and second upper bound,
wherein the first illumination mechanism intensity is adjusted when the ambient light intensity is less than the first lower bound and greater than the first upper bound, and
wherein the second illumination mechanism intensity is adjusted when the ambient light intensity is less than the second lower bound and greater than the second upper bound.

wherein the first illumination mechanism intensity is adjusted when the ambient light intensity is less than the first lower bound and greater than the first upper bound,
wherein the second illumination mechanism intensity is adjusted when the ambient light intensity is less than the second lower bound and greater than the second upper bound.
