1. An exposure control method, applied to an electronic device having a photographing function, wherein the electronic device comprises a photosensitive sensor, and the method comprises:
separately determining a depth of field parameter, a movement level parameter, and a noise intensity factor, wherein the depth of field parameter is used to represent depth of field information of a viewfinder picture during photographing, the movement level parameter is used to represent a movement amplitude of a subject or a movement amplitude of the electronic device, and the noise intensity factor is used to represent noise intensity;
determining exposure parameters based on the depth of field parameter, the movement level parameter, and the noise intensity factor, wherein the exposure parameters comprise an aperture value, an exposure time value, and light sensitivity of the photosensitive sensor; and
controlling an aperture value, a shutter speed, and light sensitivity that are of the electronic device during photographing previewing and/or photographing based on the exposure parameters.
