Lens driver circuit with ringing compensation

A lens driver circuit (100) determines the resonant frequency at a number of positions that a lens (114) can move to, so that the lens (114) can move from an old position to a new position in two steps, where the second step occurs a delay time after the first step. The delay time can be one-half of the period of the resonant frequency at the new position. 本申请公开种透镜驱动器电路(100)，其确定在透镜(114)能够移动到的若干位置处的谐振频率，使得透镜(114)能够以两步从原位置移动到新位置，其中第二步在第步之后的延迟时间发生。该延迟时间可为在新位置处的谐振频率的周期的半。
