Method for sharing images and electronic device performing thereof

1. An electronic device for a head-mounted device (HMD), the electronic device comprising:

a display;

a memory configured to store virtual reality content;

a sensor module;

a communication circuit configured to communicate with an external device; and

a processor configured to:

play back binocular image data based on the virtual reality content on the display,

control the sensor module to detect a motion of a user,

apply user sensing data based on the detected result to data associated with playback of the binocular image data,

determine whether the virtual reality content is stored in the external device,

control the communication circuit to transmit the data associated with playback of the binocular image data and not to transmit image data based on the virtual reality content, when the processor determines that the virtual reality content is stored in the external device, and

control the communication circuit to transmit the image data based on the virtual reality content corresponding to the binocular image data, when the processor determines that the virtual reality content is not stored in the external device,

wherein the data associated with playback comprises location data in cyberspace according to a playback time of the binocular image data and field of view (FoV) data of the user in the cyberspace, and

wherein the data associated with playback is used for applying the direction and angle of view of the screen viewed by the user to virtual reality content displayed by the external device.

2. The electronic device of claim 1 , wherein the user sensing data comprises at least one of head tracking data of the user, motion data of an object in cyberspace of the virtual reality content, or motion data of the user.

3. The electronic device of claim 1 , wherein the processor is further configured to allow the communication circuit to stream the image data based on the virtual reality content to the external device.

4. The electronic device of claim 1 , wherein the processor is further configured to:

further determine whether the external device is connected to the head-mounted device, and

differently determine image data to be transmitted to the external device based on whether to be connected with the head-mounted device.

5. The electronic device of claim 4 , wherein when the external device is determined as being connected to the head-mounted device, the processor is further configured to determine the played-back binocular image data as image data to be transmitted to the external device.

6. The electronic device of claim 4 , wherein when the external device is determined as not being connected to the head-mounted device, the processor is further configured to generate mono image data corresponding to the played-back binocular image data and to determine the mono image data as the image data to be transmitted to the external device.

7. An image sharing method of an electronic device that plays back binocular image data based on virtual reality content, the method comprising:

establishing a connection with an external device;

detecting a motion of a user and generating user sensing data;

applying user sensing data based on the detected result to data associated with playback of the binocular image data;

determining whether the virtual reality content is stored in the external device;

transmitting the data associated with playback of the binocular image data, when the processor determines that the virtual reality content is stored in the external device without transmitting image data based on the virtual reality content; and

transmitting the image data based on the virtual reality content corresponding to the binocular image data, when the processor determines that the virtual reality content is not stored in the external device,

wherein the data associated with playback comprises location data in cyberspace according to a playback time of the binocular image data and field of view (FoV) data of the user in the cyberspace, and

wherein the data associated with playback is used for applying the direction and angle of view of the screen viewed by the user to virtual reality content displayed by the external device.

8. The method of claim 7 , wherein the image data based on the virtual reality content is streamed and shared.

9. The method of claim 7 , wherein the determining of whether the virtual reality content is stored in the external device further comprises determining whether the external device is connected to a head-mounted device, and

wherein the determining of the data comprises differently determining image data to be shared with the external device based on whether the external device is connected to the head-mounted device.

10. The method of claim 9 , wherein when the external device is determined as being connected to the head-mounted device, the determining of the data comprises:

determining the binocular image data as image data to be shared with the external device.

11. The method of claim 9 , wherein when the external device is determined as not being connected to the head-mounted device, the determining of the data comprises:

generating mono image data corresponding to the binocular image data; and

determining the mono image data as image data to be shared with the external device.
