A control unit generates a first control signal for camera shake correction on the basis of a first acceleration detection signal, a second acceleration detection signal, and an angular velocity signal. The first acceleration detection signal including information relating to an acceleration acting on a camera and has an alternating current (AC) waveform corresponding to the acceleration. The second acceleration detection signal including information relating to the acceleration and has an output waveform. An AC component corresponding to the acceleration is superimposed on a direct current (DC) component in the output waveform. The angular velocity signal including information relating to an angular velocity acting on the camera.
