Abstract: An optical image stabilizer of the present invention is mounted in a camera at an image size of a lens to assist an image capture device. The optical image stabilizer includes a base, a transverse frame, and a longitudinal frame. The base is provided with a pair of transverse rails and longitudinal reference magnets. The transverse frame is engaged with the transverse rails for reciprocation and is provided with a pair of longitudinal rails, transverse reference magnets and longitudinal reference magnets, wherein the longitudinal reference magnets are between the longitudinal rails. The longitudinal frame is engaged with the longitudinal rails for reciprocation and is provided with the image capture device, a transverse drive coil, and a longitudinal drive coil. The longitudinal drive coils are between the longitudinal rails and in association with the longitudinal reference magnets that the longitudinal frame may move smoothly.

Abstract: An image-capturing device includes a periscope-type zooming lens unit, an optical image stabilizing (OIS) unit, and a protecting cap. The periscope-type zooming lens unit includes a housing and a lens set that is disposed in the housing and that includes a reflective prism and an emission lens. The OIS unit is disposed externally of the periscope-type zooming lens unit and adjacent to the emission lens. The OIS unit includes a base mounted to the housing of the periscope-type zooming lens unit, a movable carrier mounted to the base, an optical sensor mounted on the movable carrier to correspond with the emission lens, and a driving mechanism operable to drive the movable carrier to move relative to the base. The protecting cap is mounted to the base of the OIS unit, and is disposed to surround an outer side of the OIS unit.
