PROBLEM TO BE SOLVED: To suppress eccentric aberration of an imaging optical system, and attain an excellent image tremor effect in an imaging device performing an image tremor by use of a plurality of correction means.SOLUTION: An angular velocity sensor 101 is configured to detect a tremor of an imaging device, and a signal division part 104 is configured to divide a tremor signal to output the divided tremor detection signal to a first amount of drive computation part 105 and a second amount of drive computation part 116, respectively. On the basis of the divided tremor detection signal, the first amount of drive and the second amount of drive are configured to be calculated, and a first correction lens and a second correction les are configured to be driven, respectively. An aberration determination part 127 is configured to change a limiter used in an amount of drive limit part 117 so that eccentric aberration of the imaging optical system occurring due to movements of two correction lenses is not large. The amount of drive limit part 117 is configured to limit the amount of drive on the basis of the limiter set according to the aberration determination result, and thereby the image tremor correction is configured to be performed while suppressing the eccentric aberration. |
