The touch sensor can be in the form of a touch film, a touch sheet and a touch pad, for example.
The touch sensor can be constructed such that it converts a variation in pressure applied to a specific portion of the display unit 151 or a variation in capacitance generated at a specific portion of the display unit 151 into an electric input signal. The touch sensor can be constructed such that it can sense pressure of touch as well as the position and area of touch.
When touch input is applied to the touch sensor, a signal corresponding to the touch input is transmitted to a touch controller. The touch controller processes the signal and transmits data corresponding to the processed signal to the controller 180. Accordingly, the controller 180 can detect a touched portion of the display 151.
Referring to FIG. 2, the proximity sensor 141 can be located in an internal region of the mobile terminal, surrounded by the touch screen, or near the touch screen. The proximity sensor senses an object approaching a predetermined sensing face or an object located near the proximity sensor using electromagnetic force or infrared rays without having mechanical contact.

The method of transmitting and receiving data and the operations of the mobile terminal 100 and the electronic device 200 for implementing the method will now be explained in detail.
The mobile terminal 100 may capture an image of the screen of the external electronic device 200 in operation S100. FIG. 5 illustrates an implementation of the operation S100.
Referring to FIG. 5, the controller 180 of the mobile terminal 100 may drive the camera 121 when a user operates a menu to display a camera preview screen on the touch screen 151.
The controller 180 may provide a soft key 20 for starting a predetermined function according to this implementation through the preview screen. The soft key 20 may have a form as shown in FIG. 5 or a slide bar shape. The soft key 20 shown in FIG. 5 is exemplary and a user interface for starting the predetermined function according to this implementation is not limited to the soft key 20.
For example, the predetermined function can be started only when the soft key 20 and a specific key included in the user input unit 130 are simultaneously selected.
When the user touches the soft key 20, the controller 180 performs the operation S100 to start the predetermined function.
For example, the controller 180 can capture the image currently displayed on the preview screen of the touch screen 151 shown in FIG. 5 as an image file when the soft key 20 is touched.
The user may display at least part of an image displayed on the display unit 210 of the electronic device 200 on the preview screen and capture a desired image.
In FIG. 5, the display unit 210 of the electronic device 200 displays multiple objects. When the user displays a specific object 11 among the multiple objects on the preview screen of the touch screen 151 and touches the soft key 20, the controller 180 can capture the image of the specific object 11 displayed on the preview screen.
Referring to FIG. 6, the controller 180 can capture an image including all the objects displayed on the display unit 210 of the electronic device 200.
