Image shake correction device for optical system and apparatus having image shake correction device for optical system

摘要

An image shake correction device and an apparatus having the image shake correction device which are capable of correcting image shake due to shaking of an optical apparatus such as camera by moving a correcting lens disposed just after a diaphragm of a camera lens dependently on the detected camera shake displacement. An X-axis actuator and Y-axis actuator is provided on a lens barrel of the correcting lens, and driven alternately to move the X-axis direction and Y-axis direction respectively based on driving time ratio of each actuator calculated dependently on the detected camera shake displacement.
