PROBLEM TO BE SOLVED: To correct image quality degradation due to image shake resulting from hand shake even if speed shaking a camera is not constant, fluctuation occurs in a direction orthogonal to a direction of shaking the camera or the speed of shaking the camera does not match a subject moving speed at a time of panning.SOLUTION: In a panning control unit, if a panning detection unit detects a panning state following panning or tilting operation, an angular velocity calculation unit determines a rotational direction that serves as a main direction of panning and a tilt angle on the basis of a magnitude relation between an absolute value of a first angular velocity and that of a second angular velocity and calculates a panning angular velocity and a tilting angular velocity that serve as reference angular velocities in a first or second direction from one of the first and second angular velocities based on this determination on the basis of a ratio based on the first and second angular velocities just before exposure and the tilt angle, and a shake correction unit calculates an image shake correction amount on the basis of difference between the first angular velocity and the panning angular velocity and difference between the second angular velocity and the tilting angular velocity. |
