When a camera shake correction function is set to "on", a control unit exposes a CCD. Simultaneously during the exposure, the control unit generates a CCD drive signal for changing relative positions of the CCD and a lens in accordance with a shake detection signal received from a pose sensor. In response to this signal, the position of the CCD is shifted in X and Y directions perpendicular to the optical axis of the lens, thereby camera shake correction is performed. Next, the control unit outputs an imaging signal obtained by using the inside of a use range for camera shake correction within the CCD. On the other hand, when the camera shake correction function is set to "off", the control unit exposes the CCD while the CCD is fixed at a center position. The control unit outputs an imaging signal obtained by using the entire area of the CCD.
