1. An imaging apparatus comprising:
an imaging optical system;
an imaging element; and
a processor,
wherein, in a first focus mode, the processor
outputs moving image data captured by the imaging element via the imaging optical system to a display destination,
detects an in-focus region in an image represented by the moving image data based on the moving image data,
senses, in a case in which a focus operation is performed, a termination of the focus operation based on a time related to the focus operation,
senses a movement direction of a focus immediately before the termination of the focus operation is sensed,
sets, in a case in which the termination of the focus operation is sensed, a subject present in the in-focus region as a tracking target to continuously perform tracking processing and auto focus control, and limits the movement direction of the focus by the auto focus control to the movement direction of the focus immediately before the termination of the focus operation is sensed, in a period from starts of the tracking processing and the auto focus control until a second time elapses, and
terminates, in a case in which the focus operation is performed again after the tracking processing and the auto focus control are started, the tracking processing and the auto focus control.
