Abstract

An electronic device according to the present invention includes: a processor; and a memory storing a program which, when executed by the processor, causes the electronic device to: perform control to change a display region of an image in accordance with an orientation change of the electronic device or in accordance with accepting a user operation and display the display region of the image on a screen; and determine a clipping region of the image to be clipped from the image based on a position of the display region of the image, wherein the image includes the display region and the clipping region and the clipping region is wider than the display region.

First claim

The invention 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 region of a part of a VR content having a first view region is displayed on a display as a display region and an azimuth and an elevation/depression angle that correspond to a position of the display region with respect to the VR content are changed in accordance with an orientation change of the electronic device or a display region change operation by a user; and
a generating unit configured to generate an edited VR content including a second view region which is narrower than the first view region in the VR content and which is based on an azimuth that corresponds to the display region regardless of an elevation/depression angle that corresponds to the display region.

2. The electronic device according to claim 1 , wherein
the generating unit generates an edited VR content including the second view region which is based on an elevation/depression angle that corresponds to a horizontal direction regardless of an elevation/depression angle that corresponds to the display region and on an azimuth that corresponds to the display region.

3. The electronic device according to claim 1 , wherein
the second view region based on an azimuth that corresponds to the display region is a region that straddles neither a zenith nor a nadir regardless of an elevation/depression angle that corresponds to the display region.

4. The electronic device according to claim 1 , wherein
the at least one memory and the at least one processor further function as a setting unit configured to set whether to enable or disable an elevation/depression angle, and
the generating unit
generates an edited VR content including a second view region which is not related to an elevation/depression angle that corresponds to the display region when the elevation/depression angle is being disabled by the setting unit, and
generates an edited VR content including a second view region based on an elevation/depression angle and an azimuth that correspond to the display region when the elevation/depression angle is being enabled by the setting unit.

5. 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 region of a part of a VR content having a first view region is displayed on a display as a display region and an azimuth and an elevation/depression angle that correspond to a position of the display region with respect to the VR content are changed in accordance with an orientation change of the electronic device or a display region change operation by a user; and
a generating unit configured to generate an edited VR content including a second view region which is narrower than the first view region in the VR content and which is based on an azimuth based on an operation for designating a region having been performed by a user and on an elevation/depression angle that corresponds to a horizontal direction.

6. The electronic device according to claim 5 , wherein
the second view region based on an azimuth based on an operation for designating a region and on an elevation/depression angle that corresponds to a horizontal direction is a region that straddles neither a zenith nor a nadir.

7. The electronic device according to claim 5 , wherein
the at least one memory and the at least one processor further function as a setting unit configured to set whether to enable or disable an elevation/depression angle, and
the generating unit
generates an edited VR content including a second view region which is not related to an elevation/depression angle that corresponds to the operation for designating a region when the elevation/depression angle is being disabled by the setting unit, and
generates an edited VR content including a second view region based on an elevation/depression angle and an azimuth that correspond to the operation for designating a region when the elevation/depression angle is being enabled by the setting unit.

8. The electronic device according to claim 4 , wherein
a setting made by the setting unit is switched over by a switching instruction by a user, and an initial setting prior to accepting the switching instruction is a disabled setting.

9. The electronic device according to claim 1 , wherein
the display controlling unit controls the second view region in the VR content so as display a guidance that guides using a graphic representing a sphere.

10. The electronic device according to claim 1 , wherein
the at least one memory and the 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.

11. The electronic device according to claim 10 , wherein
the recording unit generates one still image file storing a plurality of images based on the second view region.

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

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

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

15. A control method of an electronic device, comprising:
a display controlling step of performing control so that, on a first screen, a region of a part of a VR content having a first view region is displayed on a display as a display region and an azimuth and an elevation/depression angle that correspond to a position of the display region with respect to the VR content are changed in accordance with an orientation change of the electronic device or a display region change operation by a user; and
a generating step of generating an edited VR content including a second view region which is narrower than the first view region in the VR content and which is based on an azimuth that corresponds to the display region regardless of an elevation/depression angle that corresponds to the display region.

16. A control method of an electronic device, comprising:
a display controlling step of performing control so that, on a first screen, a region of a part of a VR content having a first view region is displayed on a display as a display region and an azimuth and an elevation/depression angle that correspond to a position of the display region with respect to the VR content are changed in accordance with an orientation change of the electronic device or a display region change operation by a user; and
a generating step of generating an edited VR content including a second view region which is narrower than the first view region in the VR content and which is based on an azimuth based on an operation for designating a region having been performed by a user and on an elevation/depression angle that corresponds to a horizontal direction.
