Wherein the filter 27 can be blue glass. In the embodiment of the present application, when the external light passes through the optical filter 27 and enters the camera module 102, the optical filter 27 can absorb the infrared light, only allow the visible light to enter the camera module 102, and prevent the stray light from entering the camera module 102, so that the photo taken by the camera module 102 is more real, and the quality of the camera module 102 is improved.

Further, referring to fig. 4, fig. 4 is a schematic structural diagram of the camera module 102 shown in fig. 1 in a second embodiment. Most technical solutions in this embodiment that are the same as those in the first embodiment are not described again.

Further, referring to fig. 5 to 7, fig. 5 is a schematic structural diagram of a state of the camera module 102 shown in fig. 1 in a third embodiment; fig. 6 is a schematic structural diagram of the camera module 102 shown in fig. 5 in another state; fig. 7 is a schematic structural diagram of the electronic apparatus 100 when the camera module 102 in the electronic apparatus 100 is in the state shown in fig. 6. Most technical solutions in this embodiment that are the same as those in the previous embodiment are not described again.

The camera module 102 further includes a moving portion 28. The moving portion 28 is connected to the first light redirecting element 24. The moving portion 28 is used for moving the first light diverting member 24 along the first direction. That is, the moving portion 28 is used to drive the first light diverting member 24 to move relative to the first lens 231. It is understood that the first lens 231 is fixed, and the first light diverting member 24 can move relative to the first lens 231 under the action of the moving part 28.

Referring to fig. 5 to 7, the moving portion 28 can drive the first light redirecting element 24 to move relative to the first lens 231, so that the first light redirecting element extends (fig. 6) and retracts (fig. 5) relative to the electronic device 100. As shown in fig. 6 and 7, when the first light turning member 24 extends out relative to the electronic device 100, the first light turning member 24 exposes the light-transmitting area 103 relative to the electronic device 100, and at this time, the light-transmitting area 103 can be used for collecting light, and at this time, the electronic device 100 can take a picture. As shown in fig. 5, when the first light diverting member 24 retracts relative to the electronic device 100, the first light diverting member 24 cannot collect light because the electronic device 100 is not provided with a light hole. That is, when the electronic device 100 needs to take a picture, the moving portion 28 drives the first light diverting member 24 to move, so that the first light diverting member 24 is exposed relative to the electronic device 100, thereby taking a picture.

It can be understood that the housing 101 of the electronic device 100 does not need to be provided with a light hole for external light to enter the camera module 102. In the embodiment of the present application, the image capturing module 102 obtains the light by moving the first light diverting member 24 upwards, so that the first light diverting member 24 is exposed relative to the electronic device 100, and the light can be collected. The camera module 102 can be a front camera at this time.

As shown in fig. 5, when the first light diverting member 24 is located at the first position, the distance between the first lens 231 and the first light diverting member 24 is the first distance. It will be appreciated that the first light redirecting element 24 is now hidden from the electronic device 100. As shown in fig. 6, when the first light diverting member 24 moves from the first position to the second position, the distance between the first lens 231 and the first light diverting member 24 is the second distance. The second pitch is greater than the first pitch. When the first light diverting member 24 is located at the second position, the light collected by the first light diverting member 24 finally passes through the second lens 232 and is imaged on the image sensor 22.

In the embodiment of the present application, when the camera module 102 needs to take a picture, the moving portion 28 drives the first light redirecting part 24 to move upwards for finding a view, and when the camera module 102 does not need to take a picture, the moving portion 28 drives the first light redirecting part 24 to move downwards, so that the first light redirecting part 24 retracts into the electronic device 100, and therefore, a light-transmitting portion 26 for acquiring a scene does not need to be arranged on the electronic device 100, thereby increasing the screen occupation ratio of the electronic device 100, and realizing a full-screen.

The foregoing detailed description of the embodiments of the present application has been presented to illustrate the principles and implementations of the present application, and the above description of the embodiments is only provided to help understand the methods and their core ideas of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
