Abstract
Some embodiments include an optical image stabilization system. The optical image stabilization system includes a sensor. The sensor is configured for measuring movements of a camera module stabilized by the optical image stabilization system. Some embodiments further include an optical image stabilization control system for calculating from the movements a calculated position of a moving body. In some embodiments, the moving body is part of a camera module. Some embodiments further include an actuator control for generating electrical signals to move at least two actuators to achieve a calculated position of the moving body. In some embodiments, the actuator control system receives measurements from positions sensors that assess the position of the moving body.
