Abstract

A video display apparatus comprises an obtaining unit configured to obtain installation data representing an installation condition of a camera; an accepting unit configured to accept a movement of a cut position of a cut video obtained by cutting a part of a video captured by the camera; and a control unit configured to, based on the installation data, switch an image representing a moving direction of the cut position on the video in a case in which the movement is accepted by the accepting unit and superimpose the image on the video.

Claims

1. A video display apparatus comprising:

an obtaining unit configured to obtain installation data representing an installation condition of a camera;

an accepting unit configured to accept a movement of a cut position of a cut video obtained by cutting a part of a video captured by the camera; and

a control unit configured to, based on the installation data, switch an image representing a moving direction of the cut position on the video in a case in which the movement is accepted by the accepting unit and superimpose the image on the video.

2. The apparatus according to claim 1, wherein the accepting unit comprises:

a first accepting unit configured to accept an operation of moving the cut position of the cut video in a first direction; and

a second accepting unit configured to accept an operation of moving the cut position in a second direction different from the first direction, and

the image is an image corresponding to one of the first direction and the second direction.

3. The apparatus according to claim 2, wherein in a case in which the installation condition is one of a first installation condition to install the camera to observe a lower side from above and a second installation condition to install the camera to observe an upper side from below,

the image corresponding to the first direction is a concentric auxiliary line in the video, and

the image corresponding to the second direction is a linear auxiliary line passing through a center of the video and the cut position of the cut video.

4. The apparatus according to claim 2, wherein in a case in which the installation condition is a third installation condition to install the camera to observe in a horizontal direction,

the image corresponding to the first direction is a horizontal linear auxiliary line passing through the cut position of the cut video in the video, and

the image corresponding to the second direction is a vertical linear auxiliary line passing through the cut position of the cut video in the video and crossing the horizontal direction.

5. The apparatus according to claim 2, further comprising a notification unit configured to notify, in accordance with the setting of the installation data, that the moving direction of the cut video on the video corresponding to one of the first direction and the second direction changes.

6. The apparatus according to claim 5, wherein the notification unit notifies, in accordance with acceptance of a help operation, that the moving direction of the cut video changes.

7. The apparatus according to claim 2, further comprising a notification unit configured to notify, in accordance with the setting of the installation data, that an enabled or disabled state of an auto-flip function changes.

8. The apparatus according to claim 7, wherein the notification unit notifies, in accordance with acceptance of a help operation, that the enabled or disabled state of the auto-flip function changes.

9. The apparatus according to claim 2, wherein the operation of moving in the first direction is a pan operation, and the operation of moving in the second direction is a tilt operation.

10. The apparatus according to claim 1, wherein the video is a fish-eye video.

11. A control method of a video display apparatus including an accepting unit configured to accept a movement of a cut position of a cut video obtained by cutting a part of a video captured by a camera, the method comprising:

obtaining installation data representing an installation condition of the camera; and

switching an image representing a moving enable direction of the cut position on the video in a case in which the movement is accepted by the accepting unit and superimposing the image on the video based on the installation data.
