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. |
