Abstract: A mobile communication terminal apparatus having a communication function, the mobile communication terminal apparatus includes: 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 both 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 both the sound and the vibration by the notification setting unit and when the brightness detected by the brightness detecting unit is a predetermined brightness or less.

Abstract: A mobile terminal apparatus includes: a microphone; a switch control unit, which switches between a normal mode, in which a voice uttered toward the microphone is transmitted to an intended party, and a mute mode, in which the voice is not transmitted to the intended party; and a proximity sensor, which detects whether a detection object is in proximity to the proximity sensor, wherein, while the mute mode is being executed, if the detection object is detected by the proximity sensor, the switch control unit switches to the normal mode.

Abstract: To carry out processing to be executed upon occurrence of an emergency, a mobile phone includes a power control portion for supplying driving power, a RAM capable of storing data in the state where the driving power is not supplied from the power control portion, a crime prevention switch for detecting occurrence of an emergency, and a control portion which is driven by the driving power supplied from the power control portion. The control portion stores an emergency flag in an ON state indicating an emergency mode in the RAM in response to detection of the emergency by the crime prevention switch, and carries out emergency processing. When the control portion is activated as the supply of the driving power from the power control portion is started, it carries out the emergency processing if the emergency flag in the ON state is stored in the RAM.

Abstract: An image display device has a touchpad and an image display area that is composed of a plurality of sub-areas obtained by dividing the image display area into a two-dimensional array. A sensor surface of the touchpad is positionally correlated to the image display area. In response to a touch on the touchpad, the image display device specifies one or more of the sub-areas and adjusts the brightness of the specified sub-areas. In addition, the image display device specifies a different portion of the display image in response to a different user operation, such as a user operation of touching the touchpad with his finger and moving the finger across the touchpad, two successive user operations, or a user operation made at a specific tracing speed.
