Abstract: The embodiment of the invention provides a noise reduction method and terminal. The method comprises the steps of receiving input rotation control instructions about a rotation direction and a rotation speed, controlling a camera to rotate according to the rotation direction at the rotation speed, analyzing noise signals generated by the camera in a rotation process, obtaining attribute information of the noise signals, determining noise reduction signals according to the attribute information and superposing the noise reduction signals on the noise signals. Through the embodiment of the invention, interferences brought by the noises generated in the rotation process of the camera can be effectively reduced.
