Device for displaying content and operation method therefor
Various embodiments of the present invention relate to a device for displaying content and an operation method therefor. An electronic device of the present invention comprises a display device, at least one processor, and a memory coupled to the processor, wherein, the memory may store instructions that, when executed, cause the processor to obtain at least one deformed image corresponding to a viewpoint change on the basis of an image contained in content in response to detection of a thumbnail generation event for the content, map the obtained at least one deformed image to a three-dimensional object, obtain at least one partial image comprising at least a portion of the image mapped to the three-dimensional object, generate thumbnail content comprising the obtained at least one partial image, and control the display device to display the thumbnail content. Other embodiments may be possible.
1. An electronic device comprising:
a display device;
at least one processor; and
a memory coupled to the processor,
wherein the memory stores instructions which, when executed, cause the processor to:
obtain at least one deformed image corresponding to a viewpoint change on the basis of an image included in content in response to detection of a thumbnail generation event for the content;
map the obtained at least one deformed image to a 3-dimensional (3D) object;
obtain at least one partial image including at least a portion of the image mapped to the 3D object;
generate thumbnail content including the obtained at least one partial image; and
display the thumbnail content by controlling the display device,
wherein the instructions cause the processor to obtain the at least one partial image including at least a portion of an image mapped to the 3D object by controlling at least one of a viewpoint of a virtual camera and a motion of the 3D object.
2. The electronic device of claim 1 , wherein the instructions cause the processor to move an image included in the content in any one of an x-axis direction and a y-axis direction in order to obtain at least one deformed image corresponding to the viewpoint change.
3. The electronic device of claim 1 , wherein the instructions cause the processor to:
obtain at least one image segment from the obtained at least one deformed image;
synthesize the obtained image segment to a first region of the at least one partial image; and
generate thumbnail content including a partial image to which the first region is synthesized.
4. The electronic device of claim 1 , wherein the instructions cause the processor to:
obtain a plurality of image segments from an image mapped to the 3D object;
generate different 3D objects including the obtained plurality of image segments; and
obtain at least one partial image including at least a portion of an image mapped to the different 3D object by controlling the viewpoint of the virtual camera, and generate thumbnail content including the obtained at least one partial image.
5. The electronic device of claim 4 , wherein the instructions cause the processor to obtain the plurality of image segments on the basis of at least one of a movement of a subject, whether a sound of the subject is generated, whether a face of the subject can be recognized, and a pattern change.
6. The electronic device of claim 1 , wherein the instructions cause the processor to:
determine a thumbnail mode on the basis of a capture mode of the content and an image feature; and
generate the thumbnail content on the basis of the determined thumbnail mode.
7. The electronic device of claim 1 , wherein the instructions cause the processor to:
change a thumbnail mode of the content on the basis of a first user input; and
generate the thumbnail content on the basis of the changed thumbnail mode.
8. The electronic device of claim 1 , wherein the instructions cause the processor to reproduce the thumbnail content on the basis of at least one of a second user input, a size of the displayed thumbnail content, and whether the thumbnail content is entirely displayed.
9. The electronic device of claim 1 , wherein the instructions cause the processor to add depth information to the thumbnail content.
10. A method of operating an electronic device, the method comprising:
obtaining at least one deformed image corresponding to a viewpoint change on the basis of an image included in content in response to detection of a thumbnail generation event for the content;
mapping the obtained at least one deformed image to a 3D object;
obtaining at least one partial image including at least a portion of the image mapped to the 3D object;
generating thumbnail content including the obtained at least one partial image; and
displaying the thumbnail content,
wherein the at least one partial image including at least a portion of an image mapped to the 3D object is obtained by controlling at least one of a viewpoint of a virtual camera and a motion of the 3D object.
