1. A method comprising:
obtaining a first preview image of a to-be-photographed scene, wherein the first preview image corresponds to a first zoom ratio;
determining a target object in the first preview image;
capturing, using an image sensor and a target lens, a second original image of the to-be-photographed scene, wherein the target lens is invoked by a terminal to photograph the to-be-photographed scene at a second zoom ratio, and wherein the second zoom ratio is greater than the first zoom ratio;
determining, based on the target object and the second original image, a second preview image comprising the target object;
receiving a first operation on the target object in the second preview image, wherein the first operation determines a target location of the target object in a new preview image;
capturing, using the image sensor and the target lens, a third original image of the to-be-photographed scene;
determining, based on the target location and the third original image, a third preview image comprising the target object; and
displaying the third preview image on a display of the terminal.
