1. An image stabilization control apparatus comprising one or more processors and/or circuitry which function as:
a first detection unit that detects a subject or subjects in an input image using a learned model and outputs subject information of the detected subject or subjects;
a tracking unit that tracks one subject detected by the first detection unit in a plurality of images input consecutively;
a reliability calculation unit that calculates reliability of the tracking by the tracking unit based on the subject information; and
a first correction amount calculation unit that calculates a first correction amount to be used for image stabilization by adjusting a provisional correction amount which is based on a difference between a position of the subject being tracked by the tracking unit and a predetermined target position in an image, according to the reliability,
wherein the subject information includes at least one of a position, size, type of each subject detected by the first detection unit, and a number of the subject or subjects detected by the first detection unit, and
wherein, in a case where the reliability calculation unit detects a plurality of subjects, the reliability calculation unit lowers the reliability more in a case where a distance between the plurality of subjects is a first distance than in a case where the distance is a second distance longer than the first distance.
