Mobile terminal and method of operating the same

1. A mobile terminal comprising:

a display; and

a controller configured to:

cause the display to display an omnidirectional content;

cause the display to display an icon for setting a profile picture of an application while the omnidirectional content is displayed;

extract a plurality of faces of persons from the omnidirectional content in response to selection of the icon;

cause the display to display a plurality of face thumbnails corresponding to the extracted plurality of faces; and

set one of the plurality of face thumbnails as the profile picture of the application in response to selection of the one of the plurality of face thumbnails such that the set one of the plurality of face thumbnails is stored in a memory.

2. The mobile terminal of claim 1 , wherein:

the controller is further configured to cause the display to display an image corresponding to the one of the plurality of face thumbnails in response to the selection of the one of the plurality of face thumbnails; and

the image corresponding to the one of the plurality of thumbnails is a portion of the omnidirectional content.

3. The mobile terminal of claim 2 , wherein the controller is further configured to cause the display to display a crop box for editing a face region corresponding to the selected face thumbnail.

4. The mobile terminal of claim 1 , wherein the controller is further configured to extract a most frequently viewed image as the partial image from the omnidirectional content when the use intention information is set according to a background screen picture setting request for setting a background screen picture on the display.

5. The mobile terminal of claim 4 , wherein the controller is further configured to cause the display to display a center of the extracted partial image at an empty region included in a background screen of the display.

6. The mobile terminal of claim 1 , wherein when the use intention information is set according to a request for setting a picture for a lock screen of the mobile terminal, the controller is further configured to:

extract a most frequently viewed image as the partial image from the omnidirectional content; and

cause the display to display a center of the extracted partial image at an empty region of the lock screen.

7. The mobile terminal of claim 1 , wherein when the use intention information is set according to a request for sharing the omnidirectional content, the controller is further configured to:

obtain identification information for identifying the partial image to be extracted and displayed; and

cause transmission of the omnidirectional content, in which the obtained identification information is included, to another terminal.

8. The mobile terminal of claim 7 , wherein the identification information includes:

at least one image obtained by capturing the partial image; and

angle information indicating a position at which the partial image is located in the omnidirectional content.

9. The mobile terminal of claim 1 , further comprising a microphone configured to receive a phonetic word,

wherein the controller is further configured to:

recognize the phonetic word, which is received via the microphone while an omnidirectional image is photographed, as the use intention information; and

extract an image including an object corresponding to the recognized phonetic word as the partial image from the omnidirectional content when the omnidirectional image is photographed.

10. The mobile terminal of claim 1 , wherein the icon is displayed overlapping the displayed omnidirectional content.

11. The mobile terminal of claim 10 , wherein the icon is not a portion of the omnidirectional content.

12. A method for operating a mobile terminal, the method comprising:

displaying, on a display, an omnidirectional content and an icon for setting a profile picture of an application;

extracting a plurality of faces of persons from the omnidirectional content in response to selection of the icon;

displaying a plurality of face thumbnails corresponding to the extracted plurality of faces; and

setting one of the plurality of face thumbnails as the profile picture of the application in response to selection of the one of the plurality of face thumbnails such that the set one of the plurality of face thumbnails is stored in a memory.

13. The method of claim 12 , further comprising displaying an image corresponding to the one of the plurality of face thumbnails in response to the selection of the one of the plurality of face thumbnails,

wherein the image corresponding to the one of the plurality of thumbnails is a portion of the omnidirectional content.

14. The method of claim 13 , further comprising displaying a crop box for editing a face region corresponding to the selected face thumbnail.

15. The method of claim 12 , wherein the extracting of the partial image comprises extracting a most frequently viewed image as the partial image from the omnidirectional content when the use intention information is set according to a background screen picture setting request for setting a background screen picture on a display.

16. The method of claim 15 , wherein the displaying of the extracted partial image comprises displaying a center of the extracted partial image at an empty region included in a background screen of the display.

17. The method of claim 12 , wherein when the use intention information is set according to a request for setting a picture for a lock screen of the mobile terminal:

the extracting of the partial image comprises extracting a most frequently viewed image as the partial image from the omnidirectional content; and

the displaying of the extracted partial image comprises displaying a center of the extracted partial image at an empty region of the lock screen.

18. The method of claim 12 , wherein when the use intention information is set according to a request for sharing the omnidirectional content, the method further comprises:

obtaining identification information for identifying the partial image to be extracted and displayed; and

transmitting the omnidirectional content, in which the obtained identification information is included, to another terminal.

19. The method of claim 18 , wherein the identification information includes:

at least one image obtained by capturing the partial image; and

angle information indicating a position at which the partial image is located in the omnidirectional content.

20. The method of claim 12 , further comprising recognizing a phonetic word, which is received via a microphone while an omnidirectional image is photographed, as the use intention information,

wherein the extracting of the partial image comprises extracting an image including an object corresponding to the recognized phonetic word as the partial image from the omnidirectional content when the omnidirectional image is photographed.
