ABSTRACT:
An apparatus and method of controlling display luminosity in an operational mode in a navigation system is provided. The method includes determining a current operational mode from a plurality of operational modes of a navigation system, and automatically adjusting a display luminosity based on the determined current operational mode. The apparatus includes a key input unit configured to receive a signal of an operational mode selected by a user, a memory configured to store predetermined display luminosity levels corresponding to a plurality of operational modes and/or states of a subject, a central processing unit configured to receive the signal from the key input unit of the operational mode selected by a user and read display luminosity levels from the memory corresponding to the selected operational mode, and a display control unit configured to a receive a control signal from the central processing unit and to control a backlight control value of a display unit to control display luminosity in accordance with the selected operational mode.
