Motion blur is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation.It results when the image being recorded changes during the recording of a single exposure, either due to rapid movement or long exposure.n such an image, any object moving with respect to the camera will look blurred or smeared along the direction of relative motion. This smearing may occur on an object that is moving or on a static background if the camera is moving.
