Abstract
A control device configured to track a subject by controlling a correcting lens so that the subject is moved to a target position of a photographed image. The control device performs feedback control so that a difference between a position of the subject and a target position of the subject in the photographed image becomes small. The control device detects a photographing condition and changes a degree of tracking of the subject by changing a control gain in the feedback control based on the detected photographing condition.
