Abstract: A method of controlling a mobile communication device, and which includes allowing, via a wireless communication unit, wireless communication with at least one other terminal, displaying, via a camera, a real-time image on a first display portion of a display of the device, receiving an image capture command signal to obtain one or more captured images of the real-time image displayed on the first display portion, and displaying the one or more captured images on a second display portion and displaying the real-time image on the first display portion such that a user is allowed to view the one or more captured images and the real-time image together. Further, the one or more captured images is minimized and moved toward the second display portion and is displayed in a thumbnail format on the second display portion in response to the image capture command signal.

Abstract: A mobile communication terminal with a camera and a dual-display unit, whereby, in an image capturing mode, a first display unit displays an image of a subject received through a camera in real time and a second display unit displays a still image of the subject captured according to an image capture command signal received from a user, and in an image editing mode, when one of at least two or more images displayed on the first display unit is selected, the selected image is displayed on the second display unit, and at the same time, when a certain function icon provided to the first display nit is selected, a function allocated to the selected function icon is executed. An image of a camera preview and a captured image are displayed on each different display unit, so a user can capture a moment an image is to be captured and check the recently captured image by naked eyes, enhancing user convenience and providing fun to users.

Abstract: A mobile communication terminal having a function of displaying a communication state and a method thereof are disclosed. The method of displaying a communication state in a case of a multiparty call using a mobile communication terminal having a plurality of display units includes displaying information on one calling party on a first display unit, and displaying information on the other calling party on a second display unit. Here, information on one calling party and information on another calling party can be switched with each other and displayed on the different display units, and therefore voice communication is possible between one or more of the parties at the same time.

Abstract: The invention is directed to a method of displaying multimedia data and providing multitasking features and a mobile communications terminal capable of implementing the same; and cradle for the mobile communications terminal. A mobile communications terminal includes a transceiver, a memory, a first display unit, a second display unit, a processor, a sensor to detect a rotational movement of a body, and a cradle for displaying multimedia contents is provided. The display unit can display the multimedia data in a fixed viewing angle regardless of which direction a user rotates the terminal.

Abstract: A terminal is disclosed. The terminal includes a touch screen type display part for displaying key buttons used for a user to input information to the terminal, a speaker part for outputting an audio signal, when the user has correctly touched the key buttons, to inform the user that the key buttons have been correctly touched and inputted, and a control part for controlling the display part and the speaker part. According to the present invention, when a user of the terminal correctly touches the key buttons on the touch screen of the terminal, the user of the terminal can perceive, in the form of visual sensation, hearing sensation, and/or vibration sensation, that the key buttons have been correctly touched, and therefore, it is possible to more easily and conveniently manipulate the key buttons on the terminal having the touch screen.
