  • Patent number: 7233807
    Abstract: A device and method for displaying image data and user interface (UI) data in a mobile terminal. A camera outputs captured image data to be displayed and a synchronous signal. The mobile terminal generates UI data. In response to the synchronous signal from the camera, a selector divides a frame data time into a first time and a second time. The selector selects and outputs the image data in the first time. The selector selects and outputs the UI data in the second time. A display unit displays the image data and UI data output from the selector on corresponding display areas.

  • Publication number: 20070120964
    Abstract: A method for performing a recording operation in a video communication mode of a wireless terminal are provided, where the video communication mode of the wireless terminal is switched to a recording mode for performing the recording operation, and video data are evaluated to determine if received in the recording mode of video communication. When the video data are not received, although a predetermined time passes, the recording mode of the video communication is performed while inserting preset substitution image data. When the video data are received before the predetermined time passes, the received video data is checked to determine if an error is included, and when the received video data includes abnormal video data, the recording mode of the video communication is performed while inserting preset substitution image data.

  • Publication number: 20070064093
    Abstract: Disclosed is a method for performing a video communication service in a mobile communication terminal, including: presetting image data for substituting for video data transmitted from a transmission-side terminal; determining if the video data transmitted from the transmission-side terminal are abnormal data in video communication; and when the video data are abnormal data, replacing the video data with the preset image data and displaying the image data. When video data transmitted from a transmission-side terminal are abnormal data in video communication, image data set by a user are output instead of the abnormal data, so that a video communication service can be performed without the stoppage or distortion of a video data output screen. When any video data are not transmitted from a transmission-side terminal in video communication, image data set by a user are displayed so that a video communication service even can be efficiently performed.
