1. A target object tracking method, comprising:
obtaining a telephoto image captured by a telephoto lens and a wide-angle image captured by a wide-angle lens, and detecting whether a target object is present in the wide-angle image;
in response that the target object is present in the wide-angle image, obtaining a first zoom magnification of the wide-angle image, and obtaining a zoom magnification of switching lenses, wherein the zoom magnification of switching lenses is a ratio of a focal length of the telephoto lens to a focal length of the wide-angle lens;
in response that the first zoom magnification is less than or equal to the zoom magnification of switching lenses, outputting a tracking image of the target object by digitally zooming the wide-angle image according to the first zoom magnification;
in response that the first zoom magnification is greater than the zoom magnification of switching lenses, detecting whether the target object is present in the telephoto image; and
in response that the target object is present in the telephoto image, outputting the tracking image of the target object by digitally zooming the telephoto image.
