A method and a terminal are provided by various embodiments of the present invention in which: M cameras are configured to continuously shoot a same scene for K times, where M≥2, K≥2, and each of the M cameras simultaneously collects one frame of image at each time of shooting; and a processor, connected to the M cameras and configured to perform registration on images obtained at the K times of shooting, and perform temporal and spatial filtering on the registered images. In the embodiments of the present invention. Because the multiple cameras simultaneously collect an image at each time of shooting, a time interval at which a particular quantity of images are collected by the terminal is shorter than that at which the particular quantity of images are collected by a single camera, and a probability of an occurrence of hand trembling or object motion within the time interval also correspondingly decreases.
