1. A tracking control apparatus comprising:
at least one memory that stores a set of instructions; and
one or more controllers configured to function as a plurality of units comprising:
(1) a subject detecting unit configured to detect a specific subject in an image of a subject, wherein the image is formed by an image pickup optical system and captured by an image pickup portion;
(2) a motion vector detecting unit configured to detect motion vectors in the image;
(3) a moving subject detecting unit configured to, based on the detected motion vectors, detect a moving subject in the image; and
(4) a control unit configured to control a drive portion which rotates the image pickup portion for tracking control,
wherein the specific subject or the moving subject is determined as a subject to be shot which is a target of shooting,
wherein based on motion information on the subject to be shot, the control unit controls the drive portion to adjust composition for the image pickup portion and control tracking of the subject to be shot, and
wherein the moving subject detecting unit does not use motion vectors in a direction perpendicular to a tracking control direction for the image pickup portion when the moving subject detection unit detects a moving subject.
