An electronic device includes a main body and a dual-lens element and the ability of the dual-lens element to capture stereoscopic or 3D images remains notwithstanding changes in orientation of the device. The dual-lens element is rotatable on a surface of the main body and includes a rotating disk, a dual-lens module, a gravity sensor, and a controller. The gravity sensor detects a rotation direction and a rotation angle of the main body when the main body is rotated relative to a horizontal plane and the controller controls the rotating disk to rotate about the rotation angle by way of compensation, thereby maintaining the horizontal aspect of the dual-lens module.
