Abstract
Abstract In an imaging stabilizing device, a relative velocity component is detected between a barrel and a correction optical device movably supported with respect to the barrel. When an output signal thereon exceeds a predetermined value, or, when such a condition that the output signal exceeding the predetermined value is repeated predetermined times, a fixing device is actuated to fix the correction optical device with respect to the barrel.
