A mobile terminal can perform various functions.  Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files and outputting music via a speaker system, and displaying images and video on a display.  Some terminals include additional functionality which supports game playing, while other terminals are also configured as multimedia players.  More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of contents, such as videos and television programs. 
Generally, terminals can be classified into mobile terminals and stationary terminals.  In addition, the mobile terminals can be further classified into handheld terminals and vehicle mounted terminals. 
There are ongoing efforts to support and increase the functionality of mobile terminals.  Such efforts include software and hardware improvements, as well as changes and improvements in the structural components which form the mobile terminal. 
Techniques for taking photos using a camera of the mobile terminal or techniques for editing the taken photos have been generalized already.  Generally, a camera is built in each of front and rear sides of a mobile terminal.  In particular, the rear camera is mainly used for photographing a third party or a background, while the front camera is mainly used for the user of the mobile terminal to photograph himself. 
However, the functions of the cameras are limited and thus can inconvenience the user.
