whether or not the shooting direction of the first image-capturing device has been changed from the direction facing the first object to the direction facing the second object is determined based on change in a object detected from a shot image of the first image-capturing device.

3 . The control device according to claim 1 , wherein

in the control processing, in a case in which the shooting direction of the first image-capturing device is the direction facing the first object and the first object ceases to be detected from a shot image of the first image-capturing device, or in a case in which the shooting direction of the first image-capturing device is changed to the direction facing the second object but the second object is not detected from the shot image of the first image-capturing device, the shooting direction of the image-capturing devices included in the second group is not changed from the direction facing the third object.

4 . The control device according to claim 1 , wherein

the first object and the third object are the same object.

5 . The control device according to claim 1 , wherein

the first object and the fourth object are the same object.

6 . The control device according to claim 1 , wherein

the second object and the third object are the same object.

7 . The control device according to claim 1 , wherein

the second object and the fourth object are the same object.

8 . The control device according to claim 1 , wherein

the third object and the first object are different objects.

9 . The control device according to claim 1 , wherein

the fourth object and the second object are different objects.

10 . The control device according to claim 1 , wherein the program, when executed by the processor, further causes the control device to:

execute dividing processing of dividing the plurality of the second image-capturing devices into the first group and the second group, based on positions of each of the plurality of the second image-capturing devices.

11 . The control device according to claim 10 , wherein,

in the dividing processing, the plurality of the second image-capturing devices are divided into the first group and the second group on the basis of at least one of relative positions between each position of the plurality of the second image-capturing devices and the fourth object, and relative positions between each position of the plurality of the second image-capturing devices and the third object.

12 . The control device according to claim 10 , wherein,

in the dividing processing, the plurality of the second image-capturing devices are divided into the first group and the second group on the basis of at least one of distances between each position of the plurality of the second image-capturing devices and the fourth object, and distances between each position of the plurality of the second image-capturing devices and the third object.

13 . The control device according to claim 10 , wherein,

in the dividing processing, the plurality of the second image-capturing devices are divided into the first group and the second group such that adjacent ones of the second image-capturing devices are not included in the same group.

14 . The control device according to claim 10 , wherein,

in the dividing processing, the plurality of the second image-capturing devices are divided into the first group and the second group on the basis of positions of each of the plurality of the second image-capturing devices, regions of movement of shooting directions of each of the plurality of the second image-capturing devices, and a position of the third object.

15 . The control device according to claim 10 , wherein,

in the dividing processing, the plurality of the second image-capturing devices are divided into the first group and the second group on the basis of positions of each of the plurality of the second image-capturing devices, regions of movement of shooting directions of each of the plurality of the second image-capturing devices, and a position of the fourth object.

16 . The control device according to claim 1 , wherein the program, when executed by the processor, further causes the control device to:

execute dividing processing of dividing the plurality of the second image-capturing devices into the first group and the second group, on the basis of user operations.

17 . A control method, comprising:

acquiring information indicating a shooting object of a first image-capturing device; and

controlling a shooting direction of a plurality of second image-capturing devices so as to face a shooting object corresponding to the shooting object of the first image-capturing device, wherein

in the controlling, in a case in which a shooting direction of the first image-capturing device is changed from a direction facing a first object to a direction facing a second object,

a shooting direction of image-capturing devices included in a first group, out of the plurality of the second image-capturing devices, is not changed from a direction facing a third object corresponding to the first object, and

a shooting direction of image-capturing devices included in a second group, out of the plurality of the second image-capturing devices, is changed from the direction facing the third object, to a direction facing a fourth object corresponding to the second object, and

in the controlling, after the shooting direction of the image-capturing devices included in the second group is changed to the direction facing the fourth object, the shooting direction of the image-capturing devices included in the first group is changed from the direction facing the third object to the direction facing the fourth object.

18 . A non-transitory computer readable medium that stores a program,

wherein the program causes a computer to execute a control method comprising:

acquiring information indicating a shooting object of a first image-capturing device; and

controlling a shooting direction of a plurality of second image-capturing devices so as to face a shooting object corresponding to the shooting object of the first image-capturing device, wherein

in the controlling, in a case in which a shooting direction of the first image-capturing device is changed from a direction facing a first object to a direction facing a second object,

a shooting direction of image-capturing devices included in a first group, out of the plurality of the second image-capturing devices, is not changed from a direction facing a third object corresponding to the first object, and

a shooting direction of image-capturing devices included in a second group, out of the plurality of the second image-capturing devices, is changed from the direction facing the third object, to a direction facing a fourth object corresponding to the second object, and

in the controlling, after the shooting direction of the image-capturing devices included in the second group is changed to the direction facing the fourth object, the shooting direction of the image-capturing devices included in the first group is changed from the direction facing the third object to the direction facing the fourth object.
