Abstract
A miniature MEMS autofocus camera module includes a MEMS actuated movable lens group and at least one fixed lens group defining an optical axis within a camera module housing. Objects disposed an arbitrary distance from the camera module are automatically focused at a determined zoom to an image sensor. MEMS actuation of the movable lens group is performed to accomplish autofocus functionality.
