Abstract
Various embodiments of the present technology may provide methods and apparatus for optical image stabilization. A system may include an actuator control circuit responsive to a sensor and a feedback signal from an actuator. The actuator control circuit may be configured to calibrate a gain applied to a drive signal based on a measured difference value of the feedback signal generated by the actuator control circuit and a predetermined difference value.
