Abstract
In an anti-shake circuit for an imaging device, a differential circuit receives an analog sensing signal and a target signal and then generates a difference signal. An analog mathematical circuit performs at least one mathematical operation on the difference signal, resulting in generation of at least one mathematical output signal. A driver receives the at least one mathematical output signal, and, accordingly, generates a driving signal and controls an actuator in order to correct the shaking movement.
