1. An electronic device displaying a related image corresponding to a screen of an external electronic device on a display unit, the electronic device comprising:

a wireless communication unit configured to include an HDMI (High Definition Multimedia Interface) standard interface connected to the external electronic device; and

a controller configured to:

capture an image of a screen displayed on the display unit when a screen capture signal is received from the external electronic device while the electronic device and the external electronic device share screens thereof through the wireless communication unit, and

transmit the capture image to the external electronic device corresponding to the related image through the HDMI standard interface when animation of moving the capture image to the related image is displayed.

2. The electronic device of claim 1 , wherein the controller is further configured to scale down the captured image to a graphical object.

3. The electronic device of claim 2 , wherein, when an input predetermined for the graphical object is received, the controller is configured to display a preview image with respect to the capture image on the display unit.

4. The electronic device of claim 2 , wherein, when an input predetermined for the graphical object is received, the controller is configured to display a menu window for sharing the capture image on the display unit.

5. The electronic device of claim 2 , wherein the display unit includes a touch screen, and

wherein, when a drag input for moving the graphical object to the related image is applied to the touch screen, the controller is configured to control the capture image to be shared with the external electronic device corresponding to the related image.

6. The electronic device of claim 1 , wherein the related image includes a plurality of related images respectively including images mirroring screens of the plurality of the external electronic devices.

7. The electronic device of claim 1 , wherein the controller is configured to control the capture image to be stored in the external electronic device corresponding to the related image in response to the capture image being moved to the related image.

8. The electronic device of claim 7 , wherein the controller is configured to control the capture image to be stored in the electronic device in response to the capture image being moved to an area on the display unit not including the related image.

9. The electronic device of claim 7 , wherein the capture image being moved to the related image includes an animation of a motion of scaling down the capture image to an icon.

10. The electronic device of claim 1 , wherein, when the screen capture signal is received while a video is played on the display unit, the controller is configured to scale down the capture image to an icon and display the icon on a screen of an external device that transmits the screen capture signal.

11. The electronic device of claim 1 , wherein the capture image corresponds to a screen displayed on the display unit and related images respectively corresponding to screens of one or more external electronic devices.

12. A method of controlling an electronic device displaying a related image corresponding to a screen of an external electronic device on a display unit, the method comprising:

capturing an image of a screen displayed on the display unit when a screen capture signal is received from the external electronic device while the electronic device and the external electronic device share screens thereof through a wireless communication unit; and

transmitting the capture image to the external electronic device corresponding to the related image through an HDMI (High Definition Multimedia Interface) standard interface of the wireless communication unit when animation of moving the capture image to the related image is displayed.
