Abstract: A remote operation system includes a user terminal 10 that includes a server function unit for operating an internal function of the terminal according to remote operation, a support terminal 20 that remotely operates the user terminal 10, and a relay server 30 that includes an access management unit for holding an access timing to start remote operation of the user terminal 10 by the support terminal 20 and executes access to the user terminal 10 at the access timing. When being accessed by the relay server 30, the user terminal 10 starts up the server function unit to notify the support terminal 20 that the server function unit has been started up. When being notified that the server function unit has been started up, the support terminal 20 starts up a remote operation application to execute remote operation of the user terminal 10.

Abstract: An apparatus and method for reducing the power consumed by mobile communication terminal having a wireless LAN connection function. When a data communication operation is started, a control unit determines whether a connection to a wireless LAN is available, and if so, detects the battery remaining amount in a battery unit. If the battery remaining amount is equal to or greater than a first threshold, data communication is performed through the wireless LAN connection. When the battery remaining amount is smaller than the first threshold, a screen for recommending connection through cellular communication is displayed on a display unit. When the battery remaining amount becomes smaller than a second threshold, which is smaller than the first threshold, a power source control unit performs a predetermined power saving operation.

Abstract: In a terminal device, when an opening angle of two display section housings is detected by an opening angle detecting section 17, and the opening angle is smaller than a predetermined angle (such as 90°), a control section 11 controls luminance of at least one of display sections 4 and 5 included in the display section housings, based on the opening angle. In a case where the display sections 4 and 5 are display devices that use backlights 8 and 9, the control section 11 controls luminance of at least one of the backlights 8 and 9 illuminating the display sections 4 and 5.

Abstract: In a terminal device 100 which includes a display section housing 1 having a display section 4 and a display section housing 2 having a display section 5 foldably connected via a hinge section 3, when a control section 11 judges that one of the display section housings 1 and 2 is substantially horizontal with respect to the gravitational force direction and a display section included in the substantially horizontal display section housing is facing upwards with respect to the gravitational force direction, and further judges that the opening angle of the display section housings 1 and 2 is greater than a predetermined angle, the display of the display section included in the display section housing judged to be substantially horizontal with respect to the gravitational force direction is switched to display for inputting text.

Abstract: An object of the present invention is to reduce the power consumed by mobile communication terminal having wireless LAN connection function. To achieve this object, when data communication operation is started, a control unit determines whether connection to wireless LAN is available, and if so, detects the battery remaining amount in battery unit If the battery remaining amount is equal to or greater than a first threshold, data communication is performed through wireless LAN connection. When the battery remaining amount is smaller than the first threshold, screen for recommending connection through cellular communication is displayed on display unit. When the battery remaining amount becomes smaller than a second threshold smaller than the first threshold, power source control unit performs predetermined power saving operation.
