6. The electronic device according to claim 3 , wherein
based on the path information, the generating unit generates a plurality of the second objects by regarding a position and an orientation of the imaging apparatus at each of a plurality of timings in the future as the predetermined position and the predetermined orientation.
7. The electronic device according to claim 1 , wherein
the generating unit determines the predetermined position and the predetermined orientation, based on changes between the position and orientation of the imaging apparatus in the past and the current position and orientation of the imaging apparatus, and generates the second object.
8. The electronic device according to claim 7 , wherein
the generating unit further generates a third object in a virtual space corresponding to an image capturing range in the case where the imaging apparatus has the position and the orientation in the past, and
the display control unit further displays the third object.
9. The electronic device according to claim 1 , wherein
the at least one processor and/or the at least one circuit further function as an acquiring unit configured to acquire information on a virtual space by recognizing a position of an object and a distance to the object in a real space.
10. The electronic device according to claim 1 , wherein
the generating unit generates the first object such that the position of the first object becomes any of: a position at a focal distance of the imaging apparatus; a position at a predetermined distance from the imaging apparatus; and a position where a size of the first object becomes a predetermined size.
11. The electronic device according to claim 1 , wherein
the generating unit generates the second object such that a relative relationship of the predetermined position and the position of the second object becomes the same as a relative relationship of the current position of the imaging apparatus and the position of the first object.
12. The electronic device according to claim 1 , wherein
the display control unit displays the second object in a case where a difference of the positions or a difference of the orientations between the first object and the second object is a threshold or more.
13. The electronic device according to claim 1 , wherein
the display control unit displays the second object in a case where a moving speed of the electronic device is not constant, or a case where a path of the movement of the electronic device is irregular.
14. The electronic device according to claim 1 , wherein
the imaging apparatus is integrated into the electronic device.
15. The electronic device according to claim 1 , wherein
the imaging apparatus is separated from the electronic device.
16. The electronic device according to claim 1 , wherein
the electronic device is a head mounted type display device.
17. The electronic device according to claim 1 , wherein
the generating unit requests an external device to perform processing to generate the first object and the second object, and acquires the first object and the second object generated by the external device.
18. A method for controlling an electronic device for supporting image capturing by the imaging apparatus, the method comprising:
a generation step of generating, in a virtual space, a first object indicating a current image capturing range of the imaging apparatus, and a second object presenting, as a moving destination of the first object, an image capturing range in a case where the imaging apparatus has a predetermined position and a predetermined orientation; and
a display control step of displaying the first object and the second object,
wherein, when it is determined that a user of the imaging apparatus has caused the first object to overlay with the second object, the second object, which corresponds to an image capturing range in a case where the imaging apparatus has a newly determined predetermined position and a newly determined predetermined orientation, is generated.
