A camera module includes an actuator coupled to one or more movable lenses of the optical train and configured to move the one or more lenses relative to the image sensor to provide zoom or autofocus or both to the camera module. The actuator is configured to position one or more lenses of the optical train by applying one or more bias voltages respectively between one or more pairs of actuator components. The camera module processor is configured to determine an orientation of the camera module for the actuator to step through an auto-focus process that is specifically tailored to one of multiple sub-ranges of camera pointing angles relative to vertical. |
