Abstract
An electronic device able to automatically select one of a plurality of lenses includes a lens module, an image sensor, a focusing module, and a processor. The lens module includes a standard lens, a macro lens, and a telephoto lens. The image sensor captures images and the focusing module controls the lenses to automatically focus on the object. The processor selects the standard lens as a current lens, obtains a first focusing distance at a first moment and a second focusing distance at a second moment, and determines to switch the current lens or not to switch according to a comparison of the first and second focusing distances. The second moment is later than the first moment. A lens switching method is also provided.
