1. An imaging apparatus comprising:
an optical system which images a subject; an image pickup device which outputs an image signal of a subject image formed by the optical system; a first angular velocity detection unit which detects a first angular velocity for rotation in a first rotation direction around a direction perpendicular to an imaging plane of the image pickup device as a first axis; a second angular velocity detection unit which detects a second angular velocity for rotation in a second rotation direction around a direction that intersects at right angles with the first axis on the imaging plane of the image pickup device as a second axis; a follow shot control unit, the follow shot control unit including a follow shot detection unit which detects whether a state is a follow shot state on the basis of the first angular velocity detected by the first angular velocity detection unit and the second angular velocity detected by the second angular velocity detection unit, and an angular velocity calculation unit which calculates a panning angular velocity and a tilting angular velocity generated by the follow shot to correct the first angular velocity and the second angular velocity when the follow shot detection unit detects that the state is the follow shot state; a blur correction unit which calculates an image blur correction amount in accordance with the first angular velocity and the second angular velocity corrected by the follow shot control unit; and a blur drive unit which drives one or both of the optical system and the image pickup device in a direction to counteract an image blur on the basis of the image blur correction amount calculated by the blur correction unit and thus corrects the image blur generated in the imaging plane of the image pickup device, wherein in the follow shot control unit, when the follow shot detection unit detects that the state is the follow shot state associated with a panning or tilting operation, the angular velocity calculation unit determines a rotation direction to be the main direction of the follow shot and an inclination angle on the basis of magnitude correlation between the absolute values of the first angular velocity and the second angular velocity, and respectively calculates, on the basis of the determination, the panning angular velocity and the tilting angular velocity to be reference angular velocities in the first or second direction based on one of the first and second angular velocities on the basis of the inclination angle immediately before exposure and the ratio between the first angular velocity and the second angular velocity, and the blur correction unit calculates the image blur correction amount on the basis of the difference between the first angular velocity and the panning angular velocity and the difference between the second angular velocity and the tilting angular velocity. |
