Image stabilizing apparatus for camera module

Abstract

The present invention relates to an image stabilizing apparatus for a camera module capable of effectively stabilizing an image of the camera module, implementing miniaturization and slimness, and reducing a manufacture cost of the camera module by supplying a two-axial correction structure to perform correction in an X axial direction or an Y axial direction of an automatic focusing unit through a ball holder having upper balls and lower balls. To achieve the object, the present invention provides an image stabilizing apparatus for a camera module including; an automatic focusing unit with slide grooves having lengths in an X axial direction or in an Y axial direction perpendicular to an optical axis on a bottom surface; a driving unit for moving the automatic focusing unit in the X axial direction or the Y axial direction; a ball holder installed on the bottom surface of the automatic focusing unit and provided with upper balls slidably coupled to the slide grooves on a top surface and lower balls on a bottom surface; and a lower guide which is installed on the bottom surface of the ball holder and includes slide grooves on a top surface, wherein the slide grooves are slidably coupled with the lower balls of the ball holder and have lengths in the Y axial direction or the X axial direction perpendicular to a longitudinal direction of the slide grooves of the automatic focusing unit.
