PROBLEM TO BE SOLVED: To enhance robustness of an image shake correction device, which corrects an image shake using a plurality of correction means, by suppressing lowering in precision of disturbance compensation related to the plurality of correction means. ! SOLUTION: An imaging device includes a first image shake correction unit 103 and a second image shake correction unit 105 which change a position of a subject image relative to a position of an imaging device in its image formation plane. A shake detection part detects a degree of a shake given to the imaging device. A first control part 501 and a second control part 508 acquire position detection information on respective image shake correction lenses, and perform feedback control so that respective lens positions converge on target positions corresponding to the shape detection result. A first disturbance observer 505 and a second disturbance observer 512 for estimating disturbance are provided for the respective control parts. A plurality of dis |
