ABSTRACT:
An image stabilizing optical device including an optical system having a first lens located on an object side and a second lens located on an imaging lens side. The first lens and the second lens are opposed to each other with a small space defined therebetween. Opposed surfaces of the first lens and the second lens have the same curvature. The image stabilizing optical device further includes a rotating mechanism located on the same center of curvature of the first and second lenses, for moving the second lens independently in two perpendicular axial directions in a plane perpendicular to an optical axis of the optical system; and a shake detecting mechanism for detecting shakes in the two perpendicular axial directions. The optical system is located in front of an imaging lens of an imaging device in proximity to the imaging lens. The rotating mechanism is driven according to a result of detection from the shake detecting mechanism to control an optical path of light incident on the optical system. Accordingly, image shake due to shaky hand movements in the imaging device can be effectively performed.
