Abstract
A target object tracking method, a camera, and a computer-readable storage medium are provided. The camera includes a telephoto lens and a wide-angle lens. The camera captures a telephoto image by the telephoto lens, and captures a wide-angle image by the wide-angle lens. When a target object is detected in the wide-angle image, a first zoom magnification of the wide-angle image and a zoom magnification of switching lenses are obtained. The wide-angle image is digitally zoomed according to the first zoom magnification if the first zoom magnification is less than or equal to the zoom magnification of switching lenses. Otherwise, if the first zoom magnification is greater than the zoom magnification of switching lenses, the telephoto image is digitally zoomed to output a tracking image of the target object when the target object is detected in the telephoto image.
