Abstract:
A mobile communication terminal includes a display unit comprising a plurality of displays, one of which being formed as a touch panel, and a controller for analyzing a signal inputted through the touch panel to determine whether movement distance of data satisfies pre-set conditions, and outputting a control signal for displaying the corresponding data through a different display region according to the corresponding result.
Abstract:
A lens for light emitting diode (LED) light sources which allows light emitted from an LED light source to exit the lens in a direction perpendicular to a vertical center axis of the lens. The lens of the present invention includes an inner space which is defined in a lens body having both a bottom surface and an upper reflective surface, so that light passing through the inner space is partially reflected by total internal reflection on a portion (selective transmission surface, inner reflective surface, inside reflective surface) of a boundary surface between the inner space and the lens body. Thus, light emitted from an LED light source efficiently exits the lens through a side surface. Accordingly, the lens of the present invention is used in efficient display and illumination optical systems.
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 including a controller configured to activate both a speakerphone function and an additional function on the terminal when a functional key corresponding to the additional function is selected during an existing call, and an input unit configured to input information related to the additional function during the existing call.
Abstract:
The present invention provides a mobile camera optical lens system which assures a wide view angle by dividing a view angle into two or more view angles, and simultaneously achieves the thinness of the mobile camera optical lens system by providing separate off-axis lens systems respectively corresponding to the split view angles.
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.
Abstract:
A mobile communication terminal and method of displaying information using an information display function are provided in which at least one of a gravitational motion of a display unit and a rotational motion of a display unit is detected. An information display direction is adjusted according to the detected motion. The present invention includes a display unit configured to display information, a detecting unit configured to detect at least one of a gravitational direction of the display unit and a rotational direction of the display unit and a control unit configured to adjust a display direction of the information displayed on the display unit using the at least one of the detected gravitational direction and the rotational direction.
Abstract:
An inner zoom lens system for use in a camera module having an image sensor and appropriate for an inner-focus type is provided. The inner zoom lens system includes, sequentially from an object side, a first lens group, a second lens group, a third lens group, and a fourth lens group. The first lens group is fixed and has minus refractive power. The second lens group has plus refractive power and performs a zooming operation by moving such that an interval between the first and the second lens groups is reduced when zooming from a wide angle end to a telephoto end. The third lens group has minus refractive power and moves such that a position of an image plane is corrected depending the zooming due to the movement of the second lens group. The fourth lens group has plus refractive power.
