The second lens 2 emits light to the image sensor 7 and reflects the light passing through the first lens 1 to the image sensor 7 .

The reflector 8 may be an integrally formed whole, or may be a combined reflector 8 including a fixed part and a movable part. When the reflective plate 8 is an integrally formed whole, the reflective plate 8 can reciprocate between the first position and the second position, and specifically can be rotated or a combination of movement and rotation. In a specific embodiment, when the reflector 8 moves to the first position, the light passing through the first lens 1 is blocked by the reflector 8 , and the light passing through the second lens 2 at this time is blocked by the reflector 8 . can be projected onto the image sensor 7; when the reflector 8 moves to the second position, the light passing through the second lens 2 is blocked by the reflector 8, and the light passing through the first lens 1 at this time can be reflected to the image sensor 7 .

The traditional camera module sets the lens and the image sensor opposite to each other, which will occupy a large internal space, so that the usable space of the internal components of the electronic device under the same size is further compressed. For example, the size of the battery is compressed, which affects the electronic device. duration of use. In the present invention, the image sensor 7 is arranged on the side of the lens group, which reduces the thickness of the camera module 100 and provides a better camera assembly for electronic equipment.

In addition, in order to obtain a better optical zoom effect, it is generally necessary to lengthen the focusing space, and when the reflector 8 moves to the first position, the reflector 8 is close to the first lens 1, and the The reflector 8 can not only block the outgoing light of the first lens 1, but also provide sufficient focusing space for the second lens 2; when the reflector 8 moves to the second position, the reflector The plate 8 is far away from the first lens 1. At this time, the reflector 8 can not only block the outgoing light of the second lens 2, but also reflect the light passing through the first lens 1 to the image sensor 7.

So at the same distance a larger image can be captured than a standard lens. Since the depth of field of the telephoto lens is smaller than that of the standard lens, the background can be blurred more effectively to highlight the subject in focus, and the subject and the camera module 100 are generally farther away, resulting in less distortion in the perspective of the portrait, improving the performance of the camera. the imaging effect of the camera.
