Abstract:
Provides an image blur correction device capable of accurately moving an imaging element, and an imaging device equipped therewith. The image blur correction device of the present invention includes a fixed plate (12); a moving base (14) to which an imaging element (16) is attached; support means (18) supporting a movable member; at least three drive coils (20) disposed on the movable member; a position sensor (24) disposed on the fixed member; at least three drive magnets (22) respectively attached to the fixed member in positions opposing each of the drive coils; detection means (34) for detecting blurring of an optical axis; and control means (36) for sourcing current to each of the drive coils so as to drive the movable member based on the blur of the optical axis and the position of the movable member, thereby controlling blurring of the image formed on the imaging device.
