Method for controlling a camera module, and associated camera module

Abstract

The present disclosure provides a control method for a camera module. The camera module comprises an imaging module, a sleeve module, a lens module which is mounted in the sleeve module and can move along an optical axis direction relative to the sleeve module, at least one coil, at least one magnetic component, and elastic components disposed between the lens module and the sleeve module. The method comprises: pressing the elastic components against the lens module, wherein a deformation of the elastic components perpendicular to the optical axis direction applies a radial positive pressure to the lens module, a frictional force in the optical axis direction is generated by the positive pressure on a contact surface of the elastic components and the lens module so that the frictional force can keep the lens module in a static state in the optical axis direction relative to the elastic components; and supplying current to the at least one coil, wherein the at least one coil or the at least one magnetic component optionally matches the lens module, and the lens module is subject to an electromagnetic force in the optical axis direction, the electromagnetic force acting as a driving force for the lens module to do rectilinear motion along the optical axis direction so as to drive the lens module to move.
