Method and apparatus for displaying content

1. A method of displaying content, the method performed by a device and comprising:

receiving content displayed on an external display apparatus;

displaying a partial region of an entire region of the content on the device while simultaneously displaying the entire region of the content on the external display apparatus;

generating edit information on the partial region, based on a user input to the device; and

providing first region information representing the partial region and the edit information to the external display apparatus;

detecting a movement of the device;

simultaneously changing the partial region of the entire region of the content in response to detecting the movement of the device;

displaying the changed partial region of the entire region of the content;

providing second region information representing the changed partial region to the external display apparatus, and

wherein a region is visually demarcated, based on the first region information, within the entire region of the content on the external display apparatus by outlining the region using a distinctive mark, and the demarcated region is corresponding to a location of the partial region,

wherein the demarcated region is simultaneously moved, by the external display apparatus, on the entire region of the content in response to receiving the second region information, and

wherein an identifier which is indicative of the device is displayed adjacent to the distinctive mark within the entire region of the content on the external display apparatus.

2. The method of claim 1 ,

wherein the edit information comprises information about at least one of a line, a figure, and a color which are added, changed, or removed with respect to the partial region.

3. The method of claim 1 ,

wherein the first region information is used by the external display apparatus to display the demarcated region, and the second region information is used by the external display apparatus to move the demarcated region to a location corresponding to the changed partial region.

4. The method of claim 1 ,

wherein the first region information includes coordinate information of the partial region, and the second region information includes coordinate information of the changed partial region.

5. The method of claim 4 , wherein the changing the partial region comprises:

enlarging or reducing the partial region of the entire region of the content, based on the movement of the device.

6. The method of claim 1 , wherein the receiving the content comprises receiving the content from the external display apparatus.

7. The method of claim 1 , wherein the receiving the content comprises receiving the content from a separate server that is connected with the device and the external display apparatus.

8. The method of claim 1 , the method further comprising:

receiving high image-quality content with respect to the changed partial region from the external display apparatus; and

displaying the high image-quality content.

9. The method of claim 1 , wherein the displaying the partial region further comprises:

providing coordinate information of the partial region to a separate server that is connected with the device and the external display apparatus;

receiving high image-quality content with respect to the partial region from the server; and

displaying the high image-quality content.

10. At least one non-transitory computer-readable recording medium for storing a computer program configured to be readable by at least one processor to instruct the at least one processor to execute a computer process for performing the method of claim 1 .

11. A device comprising:

a memory which stores at least one program; and

a processor which is configured to execute the at least one program,

wherein the at least one program comprises instructions which perform:

receiving content displayed on an external display apparatus;

displaying a partial region of an entire region of the content on the device while simultaneously displaying the entire region of the content on the external display apparatus;

generating edit information on the partial region, based on a user input; and

providing first region information representing the partial region and the edit information to the external display apparatus;

detecting a movement of the device;

simultaneously changing the partial region of the entire region of the content in response to detecting the movement of the device;

displaying the changed partial region of the entire region of the content;

providing second region information representing the changed partial region to the external display apparatus, and

wherein a region is visually demarcated, based on the first region information, within the entire region of the content on the external display apparatus by outlining the region using a distinctive mark, and the demarcated region is corresponding to a location of the partial region,

wherein the demarcated region is simultaneously moved, by the external display apparatus, on the entire region of the content in response to receiving the second region information, and

wherein an identifier which is indicative of the device is displayed adjacent to the distinctive mark within the entire region of the content on the external display apparatus.

12. The device of claim 11 ,

wherein the edit information comprises information about at least one of a line, a figure, and a color which are added, changed, or removed with respect to the partial region.

13. The device of claim 11 ,

wherein the first region information is used by the external display apparatus to display the demarcated region, and the second region information is used by the external display apparatus to move the demarcated region to a location corresponding to the changed partial region.

14. The device of claim 11 ,

wherein the first region information includes coordinate information of the partial region, and the second region information includes coordinate information of the changed partial region.

15. The device of claim 14 , wherein the changing the partial region comprises:

enlarging or reducing the partial region of the entire region of the content, based on the movement of the device.

16. The device of claim 11 , wherein the receiving the content comprises receiving the content from the external display apparatus.

17. The device of claim 11 , wherein the receiving the content comprises receiving the content from a separate server that is connected with the device and the external display apparatus.

18. The device of claim 11 , wherein the at least one program comprises further instructions which perform:

receiving high image-quality content with respect to the changed partial region from the external display apparatus; and

displaying the high image-quality content.

19. The device of claim 11 , wherein the displaying of the partial region further comprises:

providing coordinate information of the partial region to a separate server that is connected with the device and the external display apparatus;

receiving high image-quality content with respect to the partial region from the server; and

displaying the high image-quality content.
