1. An image stabilization control device including at least one processor or circuit configured to function as:
a rotation radius calculation unit configured to calculate a rotation radius of an angle blur based on outputs of an angle blur signal acquired from an angle blur detection unit and a parallel blur signal acquired from a parallel blur detection unit;
a rotation radius prediction unit configured to predict a change in the rotation radius based on an output of the rotation radius calculation unit and output a rotation radius prediction signal; and
a blur correction control unit configured to control correction of the parallel blur based on the rotation radius prediction signal of the rotation radius prediction unit and the angle blur signal acquired from the angle blur detection unit.
