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: Embodiments of this application provide a time-lapse shooting method and a device, and relate to the field of shooting technologies. Therefore, a shooting scenario may be automatically identified, a plurality of photos with a relatively good effect are obtained through shooting based on a target shooting parameter that matches the shooting scenario, and video coding is performed on the plurality of photos to generate a time-lapse video with a relatively good effect.
