An apparatus and method for identifying and recognizing a connection of a portable digital camera or an ear-microphone when the portable digital camera or the ear-microphone is connected to a mobile communication terminal through its single external input terminal are disclosed. When any jack is inserted into a jack connector of the mobile communication terminal, a jack sensor outputs a sensing signal to a controller. When the controller receives the sensing signal, it controls a switching unit having switches. If there is data to be inputted from the jack connector within a predetermined time period, the controller recognizes that the digital camera has been connected to the jack connector and then changes an operating mode to a camera mode. On the other hand, if there is no data to be inputted from the jack connector for the predetermined time period, the controller recognizes that the ear-microphone has been connected to the jack connector and then changes the operating mode to an ear-microphone mode.
