Abstract

In an electronic device according to the present invention, on a first screen, a range of a part of a VR content having a first video range is displayed as a display range and the display range is changed in accordance with an orientation change of the electronic device or a display range change operation, and on a second screen, a first image with a second video range that is narrower than the first video range and a second image with a range outside of the second video range in the first video range are displayed side by side; an edited VR content including the second video range is generated; and the second video range is changed in accordance with a video range change operation in a state where the first image and the second image are being displayed on the second screen.

First claim

What is claimed is:

1. An electronic device comprising at least one memory and at least one processor which function as:
a display controlling unit configured to perform control so that, on a first screen, a part of a VR content having a first video range is displayed on a display as a display range and a position of the display range is changed in accordance with an orientation change of the electronic device or a display range change operation by a user, a second video range that is narrower than the first video range in the VR content is determined based on the changed display range, and on a second screen, a first image corresponding to whole of the second video range and a second image corresponding to whole of a third video range that is outside of the second video range in the first video range are displayed separately side by side in same display mode;
a changing unit configured to change the second video range in accordance with a video range change operation by the user in a state where the first image and the second image are being displayed on the second screen, wherein the third video range is also automatically changed with the change of the second video range; and
a generating unit configured to generate an edited VR content corresponding to the second video range in the VR content.

2. The electronic device according to claim 1 , wherein
the first image is an image into which the second video range is entirely fitted, and
the second image is an image into which the range outside of the second video range is entirely fitted.

3. The electronic device according to claim 1 , wherein
the first image and the second image are distorted circular images.

4. The electronic device according to claim 1 , wherein
the display controlling unit performs control so that, on the second screen, in a case of displaying one of the first image and the second image by enlarging or reducing the one image, other of the first image and the second image is displayed without enlarging and reducing the other image.

5. The electronic device according to claim 1 , wherein
the display controlling unit performs control so that, on the second screen, the second image is displayed in such a manner that the second image be identifiable as an image of the range outside of the second video range in the VR content.

6. The electronic device according to claim 1 , wherein
the at least one memory and at least one processor further function as a recording unit configured to generate and record a file storing the edited VR content generated by the generating unit.

7. The electronic device according to claim 5 , wherein the second image is displayed and applied a semi-transparent mask of a prescribed color or a color conversion.

8. The electronic device according to claim 6 , wherein
the recording unit generates one still image file storing a plurality of images on based on the second video range.

9. The electronic device according to claim 8 , wherein
a character string “.vr” is described before an extension in a file name of the still image file.

10. The electronic device according to claim 9 , wherein
the recording unit generates one moving image file in which a plurality of moving images based on the second video range are arranged.

11. The electronic device according to claim 10 , wherein
a character string “.vr” is described before an extension in a file name of the moving image file.

12. The electronic device according to claim 8 , wherein
the recording unit generates one moving image file in which a plurality of moving images based on the second video range are arranged.

13. The electronic device according to claim 12 , wherein
a character string “.vr” is described before an extension in a file name of the moving image file.

14. The electronic device according to claim 6 , wherein
the recording unit generates one moving image file in which a plurality of moving images based on the second video range are arranged.

15. The electronic device according to claim 14 , wherein
a character string “.vr” is described before an extension in a file name of the moving image file.

16. The electronic device according to claim 1 , wherein the first and second displayed images are not continuous with one another.

17. The electronic device according to claim 1 , wherein the first and second displayed images are displayed offset from one another.

18. The electronic device according to claim 1 , wherein the VR content includes a user-specified clipping range, an excluded region corresponding to the clipping range, and a boundary between the clipping range and the excluded region, and wherein the first and second displayed images include clipping boundaries of the clipping range which are 180 degrees apart from one another in the VR content.

19. A control method of an electronic device, comprising:
performing control so that, on a first screen, a part of a VR content having a first video range is displayed on a display as a display range and a position of the display range is changed in accordance with an orientation change of the electronic device or a display range change operation by a user, a second video range that is narrower than the first video range in the VR content is determined based on the changed display range, and on a second screen, a first image corresponding to whole of the second video range and a second image corresponding to whole of a third video range that is outside of the second video range in the first video range are displayed separately side by side in same display mode;
changing the second video range in accordance with a video range change operation by the user in a state where the first image and the second image are being displayed on the second screen, wherein the third video range is also automatically changed with the change of the second video range; and
a generating unit configured to generate an edited VR content corresponding to the second video range in the VR content.

20. A non-transitory computer readable medium that stores a program, wherein
the program causes a computer to execute a control method of an electronic device, comprising:
performing control so that, on a first screen, a part of a VR content having a first video range is displayed on a display as a display range and a position of the display range is changed in accordance with an orientation change of the electronic device or a display range change operation by a user, a second video range that is narrower than the first video range in the VR content is determined based on the changed display range, and on a second screen, a first image corresponding to whole of the second video range and a second image corresponding to whole of a third video range that is outside of the second video range in the first video range are displayed separately side by side in same display mode;
changing the second video range in accordance with a video range change operation by the user in a state where the first image and the second image are being displayed on the second screen, wherein the third video range is also automatically changed with the change of the second video range; and
a generating unit configured to generate an edited VR content corresponding to the second video range in the VR content.
