Disclosed is a mobile communication terminal having a camera function and a method of controlling a photographing process thereof. According to an embodiment of the disclosure, the mobile communication terminal comprises two buttons relating to the camera function positioned separately on a main body of the terminal. A first button is a photographing button that captures an image when on-state and a second button is a supporting button, provided the user chooses to activate this function. In this setup, the mobile communication terminal protrudes a camera lens or takes a photograph only when the first and the second buttons are in the on state. Accordingly, it is possible to reduce the possibility of dropping the terminal due to carelessness during photography, and to decrease the possibility of damaging the camera lens even when the terminal is dropped on the ground.
