Abstract

An electronic device includes a display configured to display a panorama image and a processor. The processor controls to extract at least one focus by analyzing at least one object included in the panorama image and to display an area including the extracted at least one focus in the display by determining the area as a play viewpoint of the panorama image.

First claim

What is claimed is:

1. An electronic device comprising:
a display configured to display a panorama image; and
a processor,
wherein the processor is configured to:
extract at least two foci by analyzing at least one object included in the panorama image,
determine an area including a focus having the highest priority from the extracted at least two foci,
control to display the determined area including the focus having the highest priority as an initial play viewpoint, on the display,
receive a user input for moving a focus by touching a specific area on the panorama image being displayed and dragging for a predetermined distance in a right or a left direction, and
starting with the initial play viewpoint, change a play viewpoint of the panorama image to an area including a focus according to the user input.

2. The electronic device of claim 1 , wherein the processor is further configured to control to display an image determined as a play viewpoint on the display if the panorama image is a still image.

3. The electronic device of claim 1 , wherein the processor is further configured to control to display a thumbnail on the display by extracting from an image determined as a play viewpoint if the panorama image is a moving image and the thumbnail of the panorama image is requested to be displayed.

4. The electronic device of claim 1 , wherein the panorama image is a moving image.

5. The electronic device of claim 1 , wherein the processor is further configured to change the play viewpoint to an area including a focus having a lower priority than the focus currently being displayed if the focus currently being displayed stops for more than a predetermined time in a state that one of the areas including one of the extracted at least two foci is being played.

6. The electronic device of claim 3 , further comprising:
a global positioning system (GPS) configured to identify a location of the electronic device by receiving a GPS signal,
wherein the processor is further configured to:
identify landmark information corresponding to location information of the electronic device identified by the GPS, and
extract at least one object matched with the landmark information as one of the at least two foci from the at least one object included in the panorama image.

7. The electronic device of claim 6 ,
wherein the landmark information comprises text information of a landmark corresponding to the location information of the electronic device, and
wherein the processor is further configured to extract at least one object matched with the text information of the landmark as one of the at least two foci from the at least one object included in the panorama image.

8. The electronic device of claim 5 , further comprising:
a transceiver configured to:
communicate with an external server,
transmit location information of the electronic device identified by a global positioning system (GPS) to the external server, and
receive landmark information corresponding to the location information from the external server.

9. The electronic device of claim 4 , wherein the processor is further configured to extract an area having a brightness higher than a predetermined value as one of the at least two foci from the panorama image.

10. The electronic device of claim 4 , wherein the processor is further configured to:
extract at least one person object as one of the at least two foci from objects in the panorama image,
extract a moving person object as one of the at least two foci from the at least one person object, or
extract an object located at a location at which the at least one person object is/are looking as one of the at least two foci.

11. A method for controlling a display of a panorama image in an electronic device, the method comprising:
extracting at least two foci by analyzing at least one object included in the panorama image;
determining an area including a focus having the highest priority from the extracted at least two foci;
displaying the determined area including the focus having the highest priority as an initial play viewpoint;
receive a user input for moving a focus by touching a specific area on the panorama image being displayed and dragging for a predetermined distance in a right or a left direction; and
starting with the initial play viewpoint changing a play viewpoint of the panorama image to an area including a focus according to the user input.

12. The method of claim 11 , wherein the displaying of the determined area comprises:
displaying an image determined as a play viewpoint if the panorama image is a still image.

13. The method of claim 11 , wherein the displaying of the determined area comprises:
displaying a thumbnail on the display by extracting from an image determined as a play viewpoint if the panorama image is a moving image and the thumbnail of the panorama image is requested to be displayed.

14. The method of claim 11 , wherein the panorama image is a moving image.

15. The method of claim 11 , wherein the displaying of the determined area comprises:
changing the play viewpoint to an area including a focus having a lower priority than the focus currently being displayed if the focus currently being displayed stops for more than a predetermined time in a state that one of the areas including one of the at least two foci is being played.

16. The method of claim 14 , further comprising:
identifying location information of the electronic device by receiving a global positioning system (GPS) signal,
wherein the extracting of the at least two foci comprises:
identifying landmark information corresponding to the identified location information of the electronic device, and
extracting at least one object matched with the landmark information as one of the at least two foci from the at least one object included in the panorama image.

17. The method of claim 16 , wherein the identifying of the landmark information comprises:
transmitting the identified location information of the electronic device to an external server; and
receiving the landmark information corresponding to the location information from the external server.

18. The electronic device of claim 1 , wherein the processor is further configured to:
determine a priority of each of the at least two foci, and
change the play viewpoint corresponding to a focus having the next lowest priority.

19. The method of claim 11 , further comprising:
determining a priority of each of the at least two foci; and
changing the play viewpoint corresponding to a focus having the next lowest priority.
