    摘要: An image stabilization apparatus of an inertial pendulum type corrects vibration of an image by a correcting optical device relatively displaceable with respect to a barrel. The apparatus includes a restriction device for generating an operational effect which changes according to a position of the correcting optical device for restricting the relative displacement of the correcting optical device, and a controller for changing the effect of the restriction device in accordance with a focal length or a direction of displacement of the correcting optical device.
