SYSTEM AND METHOD TO DEPLOY ACTIVE DAMPENING FOR LENS RINGING AND VIBRATION

摘要

Described herein are methods, apparatus, and computer readable medium to autofocus a lens (410) of an imaging device (400). Parameters are received indicating a lens position. Lens actuator characteristics are determined. Lens damping parameters are determined based, at least in part, on the input parameters and the lens actuator characteristics. The lens damping parameters include a lens movement step size and a time delay between each step. The lens damping parameters include damping parameters for a plurality of regions of lens movement. Lens movement parameters are determined based, at least in part, on the input parameters and the lens damping parameters. The lens (410) is then autofocused by moving it according to the lens movement parameters.
