Abstract

A screen sharing method for an electronic device is provided. A first device communicates with a second device and shares a first screen. At the first device, a specific image is displayed superposed with the first screen, where the specific image is excluded from the first screen shared with the second electronic device. The second screen is thereafter shared with the second device. An intuitive user interface for editing a shared screen and thereafter sharing the edited screen is thus provided.

Claims

1. A method performed by a first electronic device, the method comprising:

communicating with a second electronic device via a direct connection and sharing a first screen;

creating and displaying a second screen by superposing a specific image retrieved from a storage in the first or second electronic device, which is excluded from the first screen, with the first screen; and

sharing the second screen with the second electronic device.

2. The method of claim 1, wherein the direct connection is a USB connection or a direct wireless connection between the first and second electronic devices.

3. The method of claim 1, wherein the communicating with the second electronic device comprises performing handshaking to exchange driver information for mutual connection with the second electronic device.

4. The method of claim 1, wherein the sharing the screen comprises displaying the same screen as that currently displayed on the second electronic device on the screen of the first electronic device or displaying a screen which is extended from a part of the screen of the second electronic device on the screen of the first electronic device.

5. The method of claim 1, wherein the displaying the second screen comprises loading an image which is stored in the first electronic device.

6. The method of claim 1, wherein the displaying the second screen comprises loading an image which is stored in the second electronic device.

7. The method of claim 1, further comprising:

identifying a touch event associated with the specific image; and

adjusting the specific image according to the touch event.

8. The method of claim 7, wherein the adjusting the specific image comprises adjusting at least one of transparency of the specific image or an intensity of a filter of the specific image according to inputted dragging.

9. The method of claim 7, wherein the adjusting the specific image comprises displaying a control object related to the specific image and moving the specific image according to movement of the control object.

10. The method of claim 7, wherein the adjusting the specific image comprises applying a filter effect to the specific image.

11. The method of claim 1, further comprising displaying at least one object which is mapped onto at least one of an application, a shortcut key, or a command for screen sharing with the second electronic device.

12. The method of claim 11, wherein at least one of the application, the shortcut key, or the command is set by a user.

13. The method of claim 1, wherein the sharing the screen created based on the specific image with the second electronic device comprises transmitting at least one drawing event which is generated associated with the specific image to the second electronic device as a report descriptor.

14. An electronic device comprising:

a communication module;

a display functionally connected with the communication module; and

a processor configured to communicate with another electronic device and share a first screen, create a second screen which includes a specific image that is excluded from the first screen shared with the other electronic device, and share the second screen with the other electronic device.

15. The electronic device of claim 14, wherein the processor is configured to display the specific image by superposing the specific image on the display.

16. The electronic device of claim 14, wherein the processor is configured to identify a touch event associated with the specific image, and adjust the specific image according to the touch event.

17. The electronic device of claim 16, wherein the processor is configured to adjust at least one of transparency of the specific image or an intensity of a filter of the specific image according to inputted dragging.

18. The electronic device of claim 16, wherein the processor is configured to display a control object related to the specific image and move the specific image according to movement of the control object.

19. The electronic device of claim 14, wherein the processor is configured to display at least one object which is mapped onto at least one of an application, a shortcut key, or a command for screen sharing with the other electronic device.

20. A non-transient computer readable recording medium comprising a program for executing operations of:

communicating, by an electronic device, with another electronic device and sharing a first screen;

displaying a specific image which is excluded from the first screen shared with the other electronic device on the first screen; and

sharing a generated second screen which includes the specific image with the other electronic device.
