2. The control apparatus according to claim 1 , wherein the instructions cause the control apparatus to control the pan and/or the tilt in accordance with the position of the tracking target detected from the image captured by the imaging unit so that the tracking target object is located at a center of the image, after it is determined that the tracking target object has entered the predetermined partial region within the image while the at least one of the pan, the tilt, the zoom is controlled in accordance with the user operation.
3. The control apparatus according to claim 2 , wherein a first mode is a mode for controlling the at least one of the pan, the tilt, the zoom in accordance with the position of the tracking target detected from the image captured by the imaging unit, and a second mode is a mode for controlling the at least one of the pan, the tilt, the zoom in accordance with the user operation, and
wherein the instructions cause the control apparatus to switch the first mode back to the second mode after controlling the pan and/or the tilt causing the tracking target object to be located at the center of the image.
4. The control apparatus according to claim 1 , wherein the instructions cause the control apparatus to control the pan and/or the tilt so that the tracking target object is located at a position shifted from a center of the image in a direction opposite to a movement direction of the tracking target object, in a case where (a) the tracking target object is located in the predetermined partial region within the image while the at least one of the pan, the tilt, the zoom is controlled in accordance with the user operation and (b) a direction by the user operation corresponds to the movement direction of the tracking target object.
5. The control apparatus according to claim 1 , wherein a size of the predetermined partial region is set based on a size of the tracking target object and a reference setting.
6. The control apparatus according to claim 1 , wherein a size of the predetermined partial region is set based on a movement speed of the tracking target object and a reference setting.
7. The control apparatus according to claim 1 , wherein the instructions cause the control apparatus to perform the detection process for detecting the tracking target object.
8. A method for controlling an imaging apparatus, the method comprising:
controlling, in a first mode, at least one of a pan, a tilt, and a zoom for an imaging unit in accordance with a user operation for operating the at least one of the pan, the tilt, and the zoom; wherein the first mode is a mode for controlling the at least one of the pan, the tilt, the zoom in accordance with the user operation,
detecting a moving object as a tracking target object in an image captured by the imaging unit;
determining, on a basis of a position of the tracking target object detected from the image, whether the tracking target object within the image captured by the imaging unit has moved and entered a predetermined partial region within the image; wherein the predetermined partial region is a part of the image, and the predetermined partial region at least includes a coordinate of any of the upper, lower, left, and right ends of the image, and
in a case where it is determined that the tracking target object has entered the predetermined partial region in the first mode, automatically starting controlling, without the user operation, at least one of the pan, the tilt, and the zoom for the imaging unit in accordance with a position of the tracking target detected from the image captured by the imaging unit, so that a distance between the tracking target object and a center of the image captured by the imaging unit decreases.
9. The method according to claim 8 , further comprising:
controlling the pan and/or the tilt so that the tracking target object is located at a center of the image, in a case where it is determined that the tracking target object has entered the predetermined partial region within the image while the at least one of the pan, the tilt, the zoom is controlled in accordance with the user operation.
10. The method according to claim 9 ,
wherein a first mode is a mode for controlling the at least one of the pan, the tilt, the zoom in accordance with the position of the tracking target detected from the image captured by the imaging unit, and a second mode is a mode for controlling the at least one of the pan, the tilt, the zoom in accordance with the user operation, and
wherein the method further comprises switching the first mode back to the second mode after controlling the pan and/or the tilt causing the tracking target object to be located at the center of the image.
11. The method according to claim 8 , further comprising:
controlling the pan and/or the tilt so that the tracking target object is located at a position shifted from a center of the image in a direction opposite to a movement direction of the tracking target object, in a case where (a) the tracking target object is included in the predetermined partial region within the image while the at least one of the pan, the tilt, the zoom is controlled in accordance with the user operation and (b) a direction by the user operation corresponds to the movement direction of the tracking target object.
12. The method according to claim 8 , wherein the predetermined partial region is a part of a whole region in the image, the predetermined partial region at least includes a coordinate of any of the upper, lower, left, and right ends of the image.
13. The method according to claim 8 , wherein a size of the predetermined partial region is set based on a size of the tracking target object and a reference setting.
