Abstract
The present invention relates to an image stabilization control device for an imaging device, the image stabilization control device stabilizing the shaking of a subject, caused by vibration applied to an imaging device, and comprising: filters for outputting rotational angular speed data in which a low-frequency component is removed from a rotational angular speed outputted from each of vibration detection sensors of an imaging device according to filter coefficients, which are variably set; a lens moving distance calculation unit processing output signals of the filters so as to calculate a lens moving distance; and a filter coefficient variable control unit for varying the filter coefficients of the filters in order to increase a lens return speed in a lens movement limited area, when the lens moving distance outputted from the lens moving distance calculation unit goes beyond the lens movement limit area having been virtually set.
