A camera shutter for exposing or shielding a camera including a supporting portion, a winding assembly, a movable cover, and a magnet is provided. The winding assembly is capable of driving the magnet to move the movable cover along a first direction while a first current passes through the winding assembly to form a first magnetic field, and to make the shielding side of the movable cover shield the camera. The winding assembly is also capable of driving the magnet to move the movable cover along a second direction while a second current passes through the winding assembly to form a second magnetic field, and to make the shielding side of the movable cover away from the camera to expose the camera.
