Abstract
An integration circuit integrates an angular velocity signal outputted from a vibration detection element and generates a shift amount signal indicating the shift amount of an imaging device. A control unit judges whether the device is in the panning state or the tilting state. The integration circuit is formed by a digital filter, which includes a register for holding an accumulation value to be an amplitude value of the shift amount signal.
