Abstract

A display apparatus capable of moving an image and a control method thereof are provided. The display apparatus includes a display unit, an interface which receives image coordinate information and image source information from an external device that displays the image, and a controller which controls the display unit to display the image using the image coordinate information and image source information. Therefore, the image can continue to move between display apparatuses while being displayed, thereby increasing user convenience.

Claims

1. A display apparatus comprising:

a display unit;

an interface which receives coordinate information regarding coordinates of an image and image source information regarding a source of the image from an external device that displays the image; and

a controller which controls the display unit to display the image using the coordinate information and the image source information.

2. The display apparatus as claimed in claim 1, wherein the coordinate information comprises coordinates of a portion of the image which is removed from a display area of the external device.

3. The display apparatus as claimed in claim 1, wherein, if a second image is displayed on the display unit instead of the image originally displayed, the controller replaces the second image with the original image and displays the original image.

4. The display apparatus as claimed in claim 3, wherein the controller controls display of the images such that the original image gradually appears on the display unit and the second image gradually disappears from the display unit in a direction in which the original image is removed from a display area of the external device.

5. The display apparatus as claimed in claim 1, wherein, if a second image is displayed on the display unit instead of the image originally displayed, the controller superimposes and displays the original image over the second image.

6. The display apparatus as claimed in claim 1, further comprising a tuner,

wherein the image source information comprises channel information regarding a channel of the image, and

wherein the controller controls the tuner to tune to a channel indicated by the channel information and to receive a signal corresponding to the image.

7. The display apparatus as claimed in claim 1, further comprising a network interface,

wherein the image source information comprises information on a uniform resource identifier (URI) of the image, and

wherein the controller controls the network interface to access the URI and receive a signal corresponding to the image.

8. The display apparatus as claimed in claim 1, wherein the interface receives an image signal corresponding to the image from the external device, and

the controller processes the received image signal such that an image portion represented by the coordinate information is displayed on the display unit.

9. A method for controlling a display apparatus, the method comprising:

receiving coordinate information regarding coordinates of an image displayed on an external device; and

displaying the image on the display apparatus using the received coordinate information.

10. The method as claimed in claim 9, wherein the coordinate information comprises coordinates of a portion of the image which is removed from a display area of the external device.

11. The method as claimed in claim 9, wherein the displaying comprises, if a second image is displayed instead of the image originally displayed, replacing the second image with the original image and displaying the original image.

12. The method as claimed in claim 11, wherein the displaying comprises gradually displaying the original image on a display area of the display apparatus while the second image gradually disappears from the display area of the display apparatus, in a direction in which the original image is removed from a display area of the external device.

13. The method as claimed in claim 9, wherein the displaying comprises, if a second image is displayed instead of the image originally displayed, superimposing and displaying the original image over the second image.

14. The method as claimed in claim 9, wherein the receiving comprises receiving image source information regarding a source of the image.

15. The method as claimed in claim 14, wherein the image source information comprises channel information regarding a channel of the image, and

further comprising tuning to a channel indicated by the channel information and receiving a signal corresponding to the image.

16. A computer readable recording medium having recorded thereon a program for executing the following operations:

displaying a first image on a first device;

displaying a second image on a second device; and

moving from the first device at least a portion of the first image; and

displaying the moved portion of the first image on the second device while displaying at least a portion of the second image,

wherein the first image is displayed on at least one of the first device and the second device during the moving.

17. The computer readable recording medium according to claim 16, wherein the movement is gradually performed based on a dragging operation by a user and wherein the moved portion of the first image is superimposed on the displayed second image.

18. The computer readable recording medium according to claim 16, wherein:

the second device comprises a broadcast tuner,

the first device comprises a touch screen panel for receiving a predetermined command,

the movement is executed based on the predetermined command, and

wherein the first image is gradually moved in a predetermined direction such that the moved portion of the first image appears on the second device in the predetermined direction and a portion of the second image disappears from being displayed on the second device in the predetermined direction.

19. The computer readable medium according to claim 16, wherein another portion of the second image is moved to and is displayed on the first device and wherein quantity of the moved second image corresponds to quantity of the moved first image.

20. The computer readable medium according to claim 16, further comprising combining by the second device the moved portion of the first image and the portion of the second image that is to be displayed on the second device.
