  • Patent number: 11317017
    Abstract: A portable communication device is provided that includes a transceiver, a memory, a touchscreen, an imaging device, and a processor. The processor is configured to obtain, using the imaging device, a first image including objects external to the portable communication device based at least in part on a first focus and a first exposure. When the objects are persons, the processor is configured to display, via the touchscreen, the first image, graphical user interface (GUI) items corresponding to each face region of the persons. The processor is also configured to move at least one of the GUI items according to a user input detected via the touchscreen, and based at least in part on the user input, replace the displayed first image with a second image using at least one of a second focus or a second exposure determined with respect to the moved position.

  • Patent number: 8044975
    Abstract: Disclosed are an apparatus and a method for providing a wallpaper. To this end, a current state of a mobile terminal is detected, particle images and fluid image reflecting the detected current state of the mobile terminal are generated, and the generated particles and the generated fluid are displayed on a preset wallpaper so as to generate a wallpaper. Then, user motion is detected, acceleration and movement amount are extracted from the detected user motion, and movement amounts and movement directions of the particles and the fluid are determined based on the extracted acceleration and movement amount. Then, the particles and fluid are displayed in reflection of the gravity on movement amounts and movement directions of particles and fluid. Accordingly, it is possible to provide a wallpaper having an effect as if an actual snow globe is moved.

  • Patent number: 7962180
    Abstract: A mobile communication terminal and method for processing missed events are disclosed. A user can check missed events on a wait screen at a glance and rapidly respond to the missed events. A controller stores the missed events received in a wait state. When the wait state is changed to an enabled state, an event displaying unit displays event icons associated with the missed events on key cells of a touch keypad. When an event icon is touched, a function executing unit executes a function associated with the touched event icon. A display changes from the wait screen to the function executing screen. Since the missed events are displayed as event icons on the touch keypad, a user can read a state of the missed events at a glance. As well, the user can read contents of the missed events that are associated with the event icon touched on the function executing screen, and rapidly respond to the missed events.
