Abstract

Provided are a display method and a video recording method for a user to perceive a position of an extraction range moving within an angle of view, wherein the display method includes an acquisition step of acquiring a reference video that is a motion picture, an extraction step of extracting an extraction video set to be smaller than an angle of view of the reference video within the angle of view from the reference video, a movement step of moving an extraction range of the extraction video over time, a first display step of displaying the extraction video on a display device, and a second display step of displaying a support video based on a positional relationship between the angle of view and the extraction range on the display device, in which the second display step is executed during execution of the first display step.

First claim

What is claimed is:

1. A display method comprising:
an acquisition step of acquiring a reference video;
an extraction step of extracting an extraction video set to be smaller than an angle of view of the reference video within the angle of view from the reference video;
a movement step of moving an extraction range of the extraction video over time;
a first display step of displaying the extraction video on a display device; and
a second display step of displaying a support video based on a positional relationship between the angle of view and the extraction range on the display device,
wherein the second display step is executed during execution of the first display step,
the display device includes a first display device and a second display device,
the first display device displays the extraction video on the first display device,
the second display device displays the support video on the second display device,
the display method further comprises a third display step of displaying text information related to at least one of the reference video or the extraction video on the second display device,
the third display step is executed during execution of both of the first display step and the second display step, and
in a case where a width and a height of the first display device are inverted during the first display step, the support video of which a width and a height are inverted is displayed on the second display device in the second display step, and the text information of which a display orientation is maintained is displayed on the second display device in the third display step.

2. The display method according to claim 1 ,
wherein the support video includes the extraction video, and
in the second display step, the support video in which a position of the extraction video in the support video is specified is displayed.

3. The display method according to claim 1 , further comprising:
a third display step of displaying information related to at least one of the reference video or the extraction video on the display device,
wherein the third display step is executed during execution of both of the first display step and the second display step.

4. The display method according to claim 1 ,
wherein in the first display step, the extraction video is displayed in a state where a display size of the extraction video is changeable, and
in the second display step, the support video is displayed in a state where an aspect ratio of the support video and a display size of the support video are changeable.

5. The display method according to claim 4 ,
wherein in the first display step, the extraction video is displayed in a state where the display size of the extraction video is changeable while an aspect ratio of the extraction video is constantly maintained, and
in the second display step, the support video is displayed in a state where the display size of the support video is changed in accordance with a change in display size of the extraction video.

6. The display method according to claim 4 ,
wherein in the second display step, the support video indicating a video of a part of the reference video is displayed in a state where the display size of the support video is changed while the aspect ratio of the support video is constantly maintained, in accordance with a change in display size of the extraction video.

7. The display method according to claim 1 ,
wherein the second display step is executed in accordance with a display scheme selected by a user from a first display scheme and a second display scheme,
in a case where the first display scheme is selected, in the second display step, the support video is displayed in a state where an aspect ratio of the support video and a display size of the support video are changeable, and
in a case where the second display scheme is selected, in the second display step, the support video indicating a video of a part of the reference video is displayed in a state where the display size of the support video is changeable while the aspect ratio of the support video is constantly maintained.

8. The display method according to claim 1 ,
wherein the acquisition step is an imaging step of capturing the reference video within the angle of view.

9. The display method according to claim 8 ,
wherein in the imaging step, the reference video is captured within the angle of view using an anamorphic lens, and
in the first display step, the extraction video is displayed by extending a size in a lateral direction of the angle of view using the anamorphic lens.

10. The display method according to claim 8 ,
wherein the movement step is executed during execution of the imaging step, and
in the movement step, at least one of a position, a size, a movement speed, or a movement direction of the extraction range is changed based on an instruction of a user received during execution of the movement step.

11. The display method according to claim 1 ,
wherein in the movement step, the extraction range is moved within the angle of view such that a subject of a tracking target set by a user enters within the extraction range.

12. The display method according to claim 1 , further comprising:
a determination step of determining whether or not a distance between an end of the angle of view and an end of the extraction range is less than a threshold value during execution of the movement step; and
an alert step of issuing an alert to a user in a case where the distance is less than the threshold value.

13. A video recording method employing the display method according to claim 1 , the video recording method comprising:
a recording step of recording the extraction video on a recording medium.

14. The display method according to claim 2 , further comprising:
a third display step of displaying information related to at least one of the reference video or the extraction video on the display device,
wherein the third display step is executed during execution of both of the first display step and the second display step.

15. The display method according to claim 2 ,
wherein in the first display step, the extraction video is displayed in a state where a display size of the extraction video is changeable, and
in the second display step, the support video is displayed in a state where an aspect ratio of the support video and a display size of the support video are changeable.

16. The display method according to claim 15 ,
wherein in the first display step, the extraction video is displayed in a state where the display size of the extraction video is changeable while an aspect ratio of the extraction video is constantly maintained, and
in the second display step, the support video is displayed in a state where the display size of the support video is changed in accordance with a change in display size of the extraction video.

17. The display method according to claim 15 ,
wherein in the second display step, the support video indicating a video of a part of the reference video is displayed in a state where the display size of the support video is changed while the aspect ratio of the support video is constantly maintained, in accordance with a change in display size of the extraction video.

18. The display method according to claim 2 ,
wherein the second display step is executed in accordance with a display scheme selected by a user from a first display scheme and a second display scheme,
in a case where the first display scheme is selected, in the second display step, the support video
