Abstract

A control device includes: a correction control unit configured to acquire a blur detection signal detected by a blur detection unit to calculate a correction amount of an image blur and control an image blur correction unit configured to correct the image blur; a subject detection unit configured to detect a position of a subject in a photographed image and acquire position information of the subject in the photographed image; a tracking control unit configured to perform tracking control of the subject based on the position information of the subject acquired by the subject detection unit to; and a setting unit configured to set a control state of the tracking control unit. The setting unit sets the control state of the tracking control unit by selecting the set control state from a plurality of control states including a first state in which a tracking subject selectable mode is not set and a second state in which the mode is set and a tracking subject is not selected. The correction control unit acquires information on the control state selected by the setting unit and performs control to change characteristics of calculating the correction amount so that an image blur correction effect in the second state is higher than an image blur correction effect in the first state.
