Abstract

Embodiments of the disclosure relate to a camera module. The base is provided with a driving member, the driving member is used for driving a lens supporting frame to move and focus along an optical axis direction, and the driving member is further configured to drive the blade driving frame to rotate around the optical axis. That is to say, the driving member for driving the light-shielding blades and the driving member for driving the lens to focus are the same, so that the number of elements of the camera module can be reduced, thereby reducing the volume and weight of the camera module, and avoiding interference between the structure for focusing in the camera module and the power mechanism for driving the light-shielding blades. The embodiments of the disclosure further disclose a camera and an electronic device.
