Image display method and apparatus

1. An image display apparatus for displaying an externally received image, the apparatus comprising:

a display unit including a screen;

a communication unit receiving a signal transmitted from a remote control device, the signal including movement information of the remote control device; and

a control unit configured to:

connect the apparatus to a mobile terminal;

display, on the screen, an image being displayed on the mobile terminal and a pointer associated with the movement information included in the signal; and

control the mobile terminal to perform a function at a specific location on a display of the mobile terminal corresponding to a location of the pointer on the screen of the image display apparatus.

2. The apparatus according to claim 1 , wherein the signal includes a coordinate value of the pointer, and the control unit controls the mobile terminal to perform the function at the specific location on the display of the mobile terminal corresponding to the coordinate value of the pointer.

3. The apparatus according to claim 2 , wherein the control unit moves the pointer corresponding to the movement of the remote control device.

4. The apparatus according to claim 1 , wherein the signal further includes information about a key operation of the remote control device, and

wherein the control unit controls the mobile terminal corresponding to the movement information and the key operation of the remote control device.

5. The apparatus according to claim 4 , wherein the control unit controls the mobile terminal to be operated by performing at least one of click, touch, drag, scroll and screen enlarge and screen reduction commands at the specific location on the display of the mobile terminal.

6. The apparatus according to claim 1 , wherein the control unit displays an indicator on the screen in response to connection between the apparatus and the mobile terminal, the indicator including information about the mobile terminal being connected with the apparatus.

7. The apparatus according to claim 1 , wherein the control unit displays a menu on the screen, and displays the image on the screen in response to a user's selection in the menu.

8. The apparatus according to claim 1 , wherein the control unit displays a broadcast content with the image being displayed on the mobile terminal, the broadcast content and the image being displayed as a Picture In Picture (PIP) on the screen.

9. The apparatus according to claim 1 , wherein the control unit displays the image that has been adjusted according to an aspect ratio of the screen.

10. The apparatus according to claim 1 , wherein the control unit displays a menu indicating an incoming call on the screen, when the incoming call is received by the mobile terminal.

11. The apparatus according to claim 10 , wherein the menu is displayed as an OSD on the image or is displayed as a Picture In Picture (PIP) with the image.

12. The apparatus according to claim 1 , wherein the apparatus is connected to the mobile terminal using a mobile high definition link (MHL).

13. A method for displaying an image input externally received on an image display apparatus including a screen, the method comprising:

connecting, by the apparatus, to a mobile terminal;

receiving a signal transmitted from a remote control device, the signal including movement information of the remote control device;

displaying, on the screen, an image being displayed on the mobile terminal and a pointer associated with the movement information included in the signal; and

controlling the mobile terminal to perform a function at a specific location on a display of the mobile terminal corresponding to a location of the pointer on the screen of the image display apparatus.

14. The method according to claim 13 , wherein the displaying step includes:

receiving, by the apparatus, the image currently being displayed on the mobile terminal;

converting the received image into a format suitable for the image display apparatus; and

displaying the image in the converted format on the screen.

15. The method according to claim 13 , further comprising:

moving the pointer on the screen corresponding to the movement of the remote control device.

16. The method according to claim 13 , wherein the signal further includes information about a key operation of the remote control device, and

wherein the controlling step controls the mobile terminal corresponding to the movement information and the key operation of the remote control device.

17. The method according to claim 13 , wherein the controlling step includes:

calculating a coordinate value of the pointer; and

determining a location of the mobile terminal corresponding to the coordinate value.

18. The method according to claim 17 , wherein the controlling step further includes:

controlling the mobile terminal to be operated by performing at least one of click, touch, drag, scroll and screen enlarge and screen reduction commands at the location of the mobile terminal.

19. The method according to claim 13 , wherein the displaying step includes:

displaying a menu on the screen; and

displaying the image on the screen response to a user's selection in the menu.
