1. A control apparatus that controls tracking shooting performed by an image capturing apparatus, the control apparatus comprising:
a detection unit configured to detect a subject in an image obtained by the image capturing apparatus;
a tracking unit configured to track the subject by controlling a capturing direction of the image capturing apparatus based on a position of the subject detected by the detection unit; and
a processing unit configured to perform predetermined processing when a lost state where the detection unit is unable to detect a subject occurs while the tracking unit is tracking the subject,
the processing unit includes:
a decision unit configured to decide whether or not it is possible to derive, with a first degree of reliability or higher, a direction of movement of a subject immediately before occurrence of the lost state, and
a determination unit configured to, if the decision unit decides that it is possible to derive the direction of movement with the first degree of reliability or higher, perform processing for determining the capturing direction of the image capturing apparatus after occurrence of the lost state based on the direction of movement, as the predetermined processing.
