Abstract:
In an example embodiment, a method for focusing a miniature camera includes applying a signal to an actuator in the camera, moving a MEMS stage movably supported by one or more flexures in response to the application of the signal, moving a lens in response to the moving of the MEMS stage, and limiting movement of the MEMS stage to substantially one degree of freedom corresponding to an optical axis of the lens.
