Integrated lens barrel

摘要

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.

1. An integrated lens barrel comprising:
a barrel having an inner diameter; and a planar autofocus mechanism mechanically disposed within the barrel inside the inner diameter, wherein the planar autofocus mechanism comprises an autofocus lens through which an optical path extends and an autofocus actuator surrounding and supporting the autofocus lens, the autofocus actuator configured to move the autofocus lens along the optical path; wherein the autofocus mechanism including the autofocus lens and the autofocus actuator are part of a stack of optical components through which the optical path extends.
