Claim Text:
1. A display control method comprising: receiving a signal corresponding to a state alteration event related to an illumination state alteration from an illuminance sensor; transferring a first request message requesting measurement data of the ambient illuminance in response to the event signal to the illuminance sensor; receiving a first replay message including the measurement data from the illuminance sensor; determining whether the measurement data included in the first reply message is within a range of illuminance level; and adjusting, if the measurement data included in the first reply message is within a range of illuminance level, screen brightness of a display unit in response to the event signal, wherein the illuminance sensor includes an illuminance meter for periodically measuring the ambient illuminance levels and a sensor managing unit for detecting an alteration in illuminance based on the ambient illuminance levels measured from the illuminance meter and for creating the state alteration event by whether the altered illumination state is maintained for a threshold period of time.
