Abstract
An integrated lens barrel for a miniature camera is disclosed. The lens barrel can include components such as a shutter, an autofocus mechanism, a zoom mechanism, and/or an image stabilization mechanism. These and/or components can define a portion of the lens barrel that increases the length of the lens barrel. An electrostatic MEMS actuator can be used to effect movement of the autofocus mechanism, zoom mechanism, and/or image stabilization mechanism. Integrating the shutter, autofocus mechanism, zoom mechanism, and/or image stabilization mechanism into the lens barrel facilitates the construction of a substantially smaller camera that is suitable for use in personal electronic devices, such as cellular telephones.
