Abstract:
A CCD support mechanism includes a CCD holder for holding a CCD, a first printed circuit board having a first printed coil, a second printed circuit board having a second printed coil, a pair of horizontal leaf springs, and a pair of vertical leaf springs. When a camera shake occurs by hand-held shooting, a VCM composed of the first printed coil and a first stationary magnet shifts the CCD, while bending the horizontal leaf springs, to counteract the camera shake in a Y-axis direction. A VCM composed of the second printed coil and a second stationary magnet shifts the CCD, while bending the vertical leaf springs, to counteract the camera shake in an X-axis direction. Current values of the VCMs are determined by feedback control by using an output signal from a shake detector as a target value and a present position from a position detector as a measurement value.
