Abstract
Embodiments of the invention provide an apparatus for controlling an actuator in an optical image stabilizer. The apparatus includes a hand-shake frequency determination unit configured to determine a hand-shake frequency based on distance data output from a distance calculator which is configured to calculate a distance based on an output from a motion sensor. The apparatus further includes a proportional-integral-derivative coefficient selection and switching controller configured to apply proportional-integral-derivative coefficients suitable for the determined hand-shake frequency to a PID controller.
