A MEMS actuator for a compact auto-focus camera module is configured to measure physical values and to estimated values each indicative of position or motion or both of a MEMS component. A smart logic component determines a set of MEMS driver control values based on analyzing the measured physical values and substituting estimated values to more accurately position the MEMS component. A MEMS driver component receives the set of MEMS driver control values and controls the position or motion, or both, of the MEMS component based on the MEMS driver control values.

Auto-focus camera module with MEMS capacitance estimator

A MEMS actuator for an auto-focus camera module is coupled with a capacitance measurement component configured to determine MEMS actuator capacitance values to be used to determine motion and displacement of the camera module, the optical module and/or one or more movable lenses thereof, and to adapt a position and alignment of the one or more movable lenses to account for a specific focus distance.

Auto-focus camera module with MEMS distance measurement

A MEMS actuator for a compact camera couples with an alignment compensation component for generating alignment compensation signals to position and align one or more movable lenses to account for a specific focus distance and for a camera module orientation and nonlinear displacement property of the one or more movable lenses.
