Photographing method and electronic device

An electronic device, comprising a display, one or more processors, a camera, and

• a memory storing one or more computer programs that, when executed by the one or more processors, enable the electronic device to perform operations comprising:
• starting the camera in response to a first operation input by a user;
• entering a first video recording mode of the camera in response to a second operation input by the user;
• capturing, by the camera in response to a third operation input by the user, first video frames;
• and
• stopping, by the camera in response to a fourth operation input by the user, capturing the first video frames, to obtain a target video, wherein
• the target video comprises M second video frames;
• an ith second video frame in the M second video frames is obtained by fusing a foreground image of a kth first video frame in the first video frames captured by the camera and a background image of a jth first video frame in the first video frames captured by the camera;
• an (i+1)th second video frame in the M second video frames is obtained by fusing a foreground image of a (k+m)th first video frame in the first video frames captured by the camera and a background image of a (j+n)th first video frame in the first video frames captured by the camera;
• and
• M>1, m≥1, n≥1, m≠n, and i, j, k, m, n, and M are positive integers.

• a background image of an ith second video frame in the M second video frames is obtained by superimposing background images of an ith first video frame captured by the camera and r first video frames before the ith first video frame;
• a foreground image of the ith second video frame is a foreground image of the ith first video frame captured by the camera;
• and i>1, and i and r are positive integers.
