Autofocus camera systems and methods |
摘要 |
A method and system for facilitating focusing of a miniature camera are disclosed. One or more lenses can be attached to a MEMS stage. The MEMS stage can be moved by a Lorentz actuator. The MEMS stage can be configured to limit movement of the lens(es) to a single degree of freedom to inhibit misalignment thereof with respect to an imaging sensor. The stage can be biased to a predefined position thereof, e.g., for focus at infinity. A metal cover can inhibit electromagnetic interference and can limit movement of the lens(es).
