Abstract: 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.

Abstract: A photographing method includes: starting a camera in response to a first operation; entering a first video recording mode in response to a second operation; capturing first video frames in response to a third operation; and stopping capturing the first video frames in response to a fourth operation, to obtain a target video. The ith second video frame in the target video is obtained by fusing a foreground image of the kth first video frame captured by the camera and a background image of the jth first video frame captured by the camera, and the (i+1)th second video frame in the target video is obtained by fusing a foreground image of the (k+m)th first video frame captured by the camera and a background image of the (j+n)th first video frame captured by the camera, where m≠n. In this way, the electronic device can record a video with a special effect.

Abstract: In a night shot mode, a photo is captured and processed based on a plurality of frames. The plurality of frames is obtained based on a plurality of parameters including an exposure duration, a light sensitivity, and a number of frames. These parameters are determined based on factors, such as whether the electronic device is in a handheld state or not, and whether the current photographing scene is a dark scene or a light source scene.
