Specifically, when the light passing through the lens 100 reaches the first image sensor 200 or the second image sensor 300, the first image sensor 200 or the The second image sensor 300 can use the photoelectric conversion function of the photoelectric device to convert the optical signal on the photosensitive surface into an electrical signal corresponding to the optical signal, so as to achieve the purpose of imaging. In general, the first image sensor 200 and the second image sensor 300 can be divided into two types, one is a widely used CCD (Charge Coupled Device, charge coupled) element, and the other is a CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide) element In this embodiment of the present invention, the specific types of the first image sensor 200 and the second image sensor 300 are not limited. The first image sensor 200 is arranged adjacent to the first reflective member 400 , and the second image sensor 300 is arranged opposite to the first reflective member 400 .

The driving mechanism can drive the first image sensor 200 and the first reflective member 400 to switch between the first state and the second state. Specifically, the driving mechanism may switch states by driving the positions of the first image sensor 200 and the first reflective member 400 to change.

When the first image sensor 200 and the first reflective member 400 are in the first state, the light collected by the lens 100 is received by the first image sensor 200, and the first image sensor 200 images according to the light collected by the lens 100, so that the light collected by the lens 100 is transmitted through The light of the lens 100 is imaged on the first image sensor 200; when the first image sensor 200 and the first reflective member 400 are in the second state, the light collected by the lens 100 is reflected by the first reflective member 400, and the first reflective member 400 400 reflects the light to the second image sensor 300, and the second image sensor 300 forms an image according to the light collected by the lens 100, that is to say, the light passing through the lens 100 is first reflected by the first reflector 400, and the reflected light is reflected in the first reflector 400. imaged on the image sensor 200 .

Of course, the camera module disclosed in the embodiment of the present application may further include a third reflective member, the third reflective member is disposed adjacent to the second image sensor 300 , and the second image sensor 300 and the third reflective member have a third state and a fourth state state. When the second image sensor 300 and the third reflective member are in the third state, the light collected by the lens 100 is reflected by the first reflective member 400, and the first reflective member 400 reflects the light to the second image sensor 300, and the second image The sensor 300 forms an image according to the light collected by the lens 100; when the second image sensor 300 and the third reflector are in the fourth state, the light collected by the lens 100 is reflected by the first reflector 400, and the first reflector 400 reflects the light onto the third reflective member, and the third reflective member reflects the light to the next path.

It should be noted that the next path may include image sensors and reflectors with the same functions and structures as the first image sensor 200 , the second image sensor 300 , and the first reflector 400 , so that the light path can be longer. Of course, the next path may also include more optical modules, which is not limited in this embodiment of the present invention.

In the specific work process, when the user needs to shoot a close-up shot, that is, when the shooting scene is close-focus, because the light path in this shooting scene is short, the light path is short, so the light directly in the first The imaging on the image sensor 200 is well thought out, and the light only needs to pass through the lens 100 to achieve focusing, and at this time, the camera module can complete the close-up imaging. When the user needs to shoot a distant view, that is, when the shooting scene is a long focus, because the light path in this shooting scene is long, the light path is long, and the light needs to be imaged on the second image sensor 300, so that the light path is long. If the light has a long path, the light can achieve the predetermined focusing effect. If the light has not achieved the focusing effect, the light needs to continue to be reflected to the next path, and so on, and finally the long-range shooting can be achieved.

This method is simple, reliable, and easy to set. When the user manually switches the states of the first image sensor 200 and the first reflective member 400, this method can facilitate the user's operation, improve the convenience of using the electronic device, and thus improve the user experience. .

In another optional embodiment, the first image sensor 200 and the first reflective member 400 are slidably disposed on the cavity 600, and the first image sensor 200 and the first reflective member 400 are in the first state and the second Sliding switching between states, so that the first image sensor 200 and the first reflective member 400 are switched between the first state and the second state by sliding.

When the light incident surface of the light guide module 900 is opposite to the second light reflecting member 700, the light reflected by the second light reflecting member 700 can enter through the light incident surface. In the light guide module 900 , because the light reflected by the second reflective member 700 requires more light for shooting, more light required for shooting can enter the light guide module 900 , and at the same time, it is difficult for other stray light to escape. The other surfaces of the light guide module 900 enter, so that the light guide module 900 can better isolate other stray light, so that the light required for shooting can stably propagate from the light exit surface to the first image sensor 200 or the first reflection 400 pieces, and finally make the imaging of the camera module clearer and the imaging quality higher.
