Claim 0:
1. An apparatus for automatically controlling a screen brightness of an audio video navigation (AVN) system, the apparatus comprising:
an illumination sensor configured to measure illumination outside a vehicle per a predetermined period;
an illumination data receiving device configured to receive illumination data transmitted per the predetermined period from the illumination sensor and determine an average of a predetermined number of the received illumination data;
a per-illumination brightness controller configured to determine target screen brightness matched to the average of the illumination data, the average being determined by the illumination data receiving device, from a previously stored default matching relationship; and
a display configured to control a screen brightness based on the target screen brightness, and
wherein the per-illumination brightness controller is configured to determine the target screen brightness based on a new customized matching relationship which is generated by correcting the screen brightness matched to each illumination data based on the default matching relationship in accordance with an input of a user who adjusts to enhance or weaken the screen brightness.
