The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.

In the present invention, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature.

As shown in fig. 1, a terminal device includes an electronic device 300 and an external lens externally connected to the electronic device 300, where the electronic device 300 includes, but is not limited to, a mobile terminal such as a smart phone and a tablet computer.

As shown in fig. 1-3, the present embodiment provides an external lens, which includes a charging module 200 and a lens module 100, wherein the charging module 200 includes a battery. The lens module 100 includes a driving element 106 and a plurality of external lenses 103, the lens module 100 can be connected with the electronic device 300, the external lenses 103 are disposed on the outer side (the side facing the outside of the electronic device 300) of the camera 301 of the electronic device 300, the driving element 106 can enable the external lenses 103 to be aligned with the camera 301 alternatively, so that the camera 301 and the external lenses 103 are overlapped, and the shooting quality of the electronic device 300 is improved. Due to the fact that the plurality of external lenses 103 are arranged, different types of external lenses 103 and cameras 301 can be overlapped according to actual requirements, the external lenses can be matched at will, switching is free, and good applicability is achieved. The battery is electrically connected with the driving piece 106 and is used for supplying power to the driving piece 106, and the external lens 103 is electrically driven by the driving piece 106, so that the external lens 103 is automatically switched, and the shooting flexibility and operability are greatly enhanced.

Optionally, the charging module 200 further includes a communication module, where the communication module can transmit a signal instruction to the driving element 106, and the driving element 106 executes the instruction of the communication module to drive the external lens 103, so as to automatically switch the external lens 103.

At least some of the external lenses 103 are different in type, and the external lenses 103 may be one of a wide-angle lens, a telephoto lens, a macro lens, a fisheye lens, a progressive gray lens, and a polarized lens, that is, the lens module 100 includes at least two of the above lenses, so as to switch the external lenses 103 according to the use requirement. In particular, since the angle of the picture photographed by the camera 301 is narrow, it is difficult to completely photograph a large scene. The wide-angle lens can increase the shot picture angle so that more scenes can be shot. Meanwhile, the wide-angle lens can also reduce the distortion of objects and increase the depth of field, so that the picture is more lifelike. The wide-angle lens is suitable for shooting large scenes such as scenery, buildings, crowds and the like, and the picture is wider.

The long-focus lens can shoot a long-distance object more clearly, and has the characteristics of longer focal length compared with a wide-angle lens and a micro-distance lens, and the shot object can be amplified by increasing the optical zoom multiple of the lens, so that high definition in shooting from a distance is realized. Some tele lenses can increase the zoom factor to more than 2-3 times, enabling a user to more easily capture distant scenes, such as distant buildings, animals, or sports scenes.

The macro lens can enable a user to shoot more fine and exquisite small objects, and has the advantages of higher magnification and clearer image quality compared with the macro shooting function of the camera 301. The macro mode of the camera 301 can only achieve 1-2 times of magnification, and the macro lens can achieve higher magnification, usually about 10 times. This means that the user can observe the details of the object more carefully, thereby achieving more artistic and photographic effects. And the macro lens can also enable a user to better control the focus and the depth of field. Because the macro shooting requires a very short shooting distance, a shallow depth of field is easy to occur, so that a part of a picture is out of focus. The macro lens can control the depth of field by adjusting the focal length, so that a user can better grasp the focal point and the expression technique of the picture.

The working principle of the fish-eye lens is that a spherical lens is utilized to twist a picture, a special circular effect is presented, meanwhile, a super wide-angle scene can be shot, and the fish-eye lens is very suitable for shooting pictures or videos of special styles. Meanwhile, due to the distortion effect of the fish-eye lens, the fish-eye lens can be used for shooting some interesting special effect photos or videos, and is very suitable for shooting lovers and creative photographers.

Gradual gray lens, polarized lens, etc., can enhance shooting effect, reduce light reflection, etc.
