Mobile communication terminal apparatus

A method of controlling a mobile communication terminal apparatus having a communication function, the mobile communication terminal apparatus including:

• a light emitting unit configured to indicate call incoming information or mail receiving information by light emission;
• a brightness detecting unit;
• and a light-emission control unit, the method comprising;
• detecting a brightness by the brightness detecting unit;
• controlling the light emitting unit to not emit light when the detected brightness is a first brightness or less, and
• controlling, after at least one of incoming call and receiving mail, the light emitting unit to emit light when the detected brightness is greater than a second brightness.

A mobile communication terminal apparatus having a communication function, the mobile communication terminal apparatus comprising:

• a light emitting unit configured to indicate call incoming information or mail receiving information by light emission;
• a notification setting unit configured to set whether to indicate at least one of the call incoming information and the mail receiving information by using at least one of a sound and a vibration;
• a brightness detecting unit, which detects a brightness when the notification setting unit set to not indicate by using the at least one of the sound and the vibration;
• and
• a light-emission control unit, which controls the light emitting unit to not emit light, when the notification setting unit set to not indicate by the at least one the sound and the vibration and when the brightness detected by the brightness detecting unit is a predetermined brightness or less.
