An angular velocity sensor detects a shake of an image pickup apparatus and a signal divide unit divides a shake detection signal to output it to each of a first drive amount calculating unit and a second drive amount calculating unit. A first drive amount and a second drive amount are calculated based on the divided shake detection signal to drive each of a first correction lens and a second correction lens. An aberration determination unit changes a limiter used in a drive amount limiting unit based on the first drive amount and the second drive amount so as not to increase the eccentric aberration of an imaging optical system generated by the movement of the two correction lenses. The drive amount limiting unit limits the drive amount based on the limiter set according to the result of the determination for the aberration to correct the image shake while suppressing the eccentric aberration.
