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 samples a plurality of amplitude values of an acceleration signal during a predetermined unit period in the panning state or the tilting state. When an average value of the sampling values exists nearer to zero than a predetermined basic threshold value, it is judged that the panning state or the tilting state is terminated.
