Abstract
The present disclosure provides a multi-lens device and method having improved autofocus. The method comprises: determining from a first focus value and second focus value whether a focus distance of a first lens or a focus distance of a second lens corresponds to a peak focus position; and adjusting the focus distance of the first lens and second lens when neither the focus distance of the first lens nor the focus distance of the second lens corresponds to the peak focus position.
