The first photosensitive chip 120 is disposed opposite to the first lens 110. The first light incident through the first lens 110 can be projected to the first photo sensor chip 120, and then converted into an electrical signal, which is converted into a digital image signal through a/D (analog/digital) conversion, and the digital image signal is transmitted to a Digital Signal Processor (DSP) for processing and forming a final picture. The first reflecting member 130 is located between the first lens 110 and the first photo-sensing chip 120 in the optical axis direction of the first lens 110. The first reflecting member 130 has a first reflecting surface for reflecting light and a first light blocking surface for blocking light. The first reflective surface faces the first photosensitive chip 120, and the first light blocking surface faces the first lens 110.
When the included angle between the second reflector 230 and the photo sensor chip 120 is a first predetermined angle, the light collected by the second lens 210 is reflected by the second reflector 230 and the first reflective surface to the first photo sensor chip 120. The first photosensitive chip 120 forms an image according to the light collected by the first lens 110 and the second lens 210, and the camera module is in a light supplement mode. At this time, the projection profile of the second reflecting member 230 is at least partially located within the projection profile of the second mirror in the optical path transmission direction of the second lens 210, that is, in the direction along the second lens 210. The first preset angle can be flexibly selected according to actual conditions, and the first preset angle is not limited in the text.
In a specific operation process, when an included angle between the second reflecting piece 230 and the first photosensitive chip 120 is a first preset angle, light collected by the second lens 210 enters the first photosensitive chip 120 through reflection of the second reflecting piece 230 and the first reflecting surface, and the amount of light entering the first photosensitive chip 120 is increased, so that the shooting brightness of the camera module is improved, and the shooting effect of the camera module in a weak light environment is improved.

At this time, in the case of the second preset angle, the second reflecting member 230 is not in the optical path transmission direction of the second lens 210, that is, in the direction along the second lens 210, the projection profile of the second reflecting member 230 is located outside the projection profile of the second lens 210.
In a specific operation process, the second reflecting member 230 cannot reflect the light passing through the second lens 210 to the first reflecting surface, and meanwhile, the portion of the light entering through the first lens 110 is shielded, so that the light transmitted to the first photosensitive chip 120 is reduced, the shooting brightness of the camera module is reduced, and the shooting effect of the camera module in a strong light environment is improved.
In the above embodiment, the switching between the first preset angle and the second preset angle may be achieved by rotating the second reflecting member 230. For example, the first predetermined angle may be an acute angle, and the second predetermined angle may be an obtuse angle or a right angle, where the first predetermined angle and the second predetermined angle refer to angles formed by the second reflecting member 230 and the first photosensitive chip 120 on the same side.
It should be noted that, when the camera module is in the fill-in mode, since the first light blocking surface faces the first lens 110, light at the edge of the first lens 110 is blocked, but the amount of light entering the second lens 210 is greater than the amount of light blocked by the first lens 110, so that the total amount of light received by the first photo sensor chip 120 is increased.
In the embodiment of the present application, the camera module has set up second reflection piece 230 to adjust the light incident amount of second camera lens 210 according to the shooting demand is nimble, make the camera module all can realize better, more diversified shooting effect under highlight environment and low light environment.

When the module of making a video recording is in the light filling mode, second reflector 230 can cover second sensitization chip 220, and then makes second sensitization chip 220 unable work, consequently makes a video recording the module under the light filling mode, first sensitization chip 120 work, and second sensitization chip 220 can not work.
In order to further improve the shooting performance of the camera module, in another alternative embodiment, the number of the second lenses 210 may be at least two, and at least two of the second lenses 210 are arranged at intervals. The number of the first reflection members 130 may be at least two, and at least two first reflection members 130 may be spaced apart. The number of the second reflective members 230 may be at least two, and at least two second reflective members 230 may be spaced apart. The at least two first reflecting members 130 and the at least two second reflecting members 230 may be disposed in one-to-one correspondence, and the at least two second lenses 210 may be disposed in one-to-one correspondence with the at least two second reflecting members 230. At this time, the light collected by each second lens 210 is reflected to the first photosensitive chip 120 through the corresponding second reflecting member 230 and the second reflecting member 230.

Meanwhile, one or more of the second lenses 210 can be selected to supplement light at the same time, so that the use scenes of the camera module are increased.
In addition, the number of the second photosensitive chips 220 may also be at least two, and the at least two second lenses 210 correspond to the at least two photosensitive chips one to one. At this time, when all the second lenses 210 are used for light compensation, all the second photosensitive chips 220 cannot operate. When part of the second lens 210 is used for light supplement and part of the second lens 210 is not used for light supplement, the second photosensitive chip 220 corresponding to the part of the second lens 210 which cannot be used for light supplement can work simultaneously with the first photosensitive chip 120, so that a better shooting effect is obtained.
In another alternative embodiment, the second reflecting member 230 is located between the first photosensitive chip 120 and the second lens 210 along the optical axis direction of the second lens 210, and the first reflecting member 130 is disposed opposite to the second reflecting member 230. In this scheme, the second reflector 230 is disposed between the second lens 210 and the first photo sensor chip 120, so that a path of a reflection light path formed by the second lens 210, the second reflector 230, and the first reflector 130 is short, thereby reducing light loss. In addition, the second reflector 230 is disposed between the second lens 210 and the first photo sensor chip 120, so that the structure of the camera module is more compact.

Meanwhile, the user can trigger the first driving mechanism to move in a wireless control manner, so as to drive the second reflecting member 230 to rotate, so that the switching operation of the second reflecting member 230 is more convenient to implement.
The structure capable of achieving the corresponding driving function is many, for example, a pneumatic transmission mechanism or a hydraulic transmission mechanism realized by a piston mechanism, a lead screw pair transmission mechanism realized by a lead screw mechanism, a transmission mechanism of a gear and rack structure and the like can drive the second reflection member 230 to rotate, or a shape memory alloy is adopted to drive the second reflection member 230 to rotate by self shape resetting.
Further, the first reflector 130 and the second reflector 230 can be all total reflection mirrors, and at this time, the reflection efficiency of the first reflector 130 and the second reflector 230 is high, so that the optical performance of the camera module is improved.
In another alternative embodiment, at least two first reflection members 130 may be symmetrically disposed with respect to the optical axis of the first lens 110 as a symmetry axis. Under the condition that the camera module is in the dimming mode, the amount of light collected by the first lens 110 blocked by each first reflecting member 130 is the same. In this scheme, under the condition that the module of making a video recording is in the dimming mode, the shading volume of first reflection piece 130 and second reflection piece 230 is the same for the part of the light that first camera lens 110 gathered is sheltered from the back by first reflection piece 130, and the middle part of first sensitization chip 120 is still aimed at to the light path between first camera lens 110 and the first sensitization chip 120, makes the formation of image of sensitization chip be difficult to deviate from the central point of first sensitization chip 120, thereby has improved the imaging quality of the module of making a video recording.
The arrangement of the first lens 110 and the at least two second lenses 210 can be selected according to actual needs, for example, the first lens 110 and the at least two second lenses 210 are distributed in a ring shape. In another alternative embodiment, at least two second lenses 210 are disposed on two opposite sides of the first lens 110 on the plane where the first photosensitive chip 120 is located.

The arrangement mode is simple and compact, and is beneficial to controlling the light source.
In order to further increase the application scenarios of the camera module, in another optional embodiment, when the included angle between the first reflecting element 130 and the first photosensitive chip 120 may be a third preset included angle, the first photosensitive chip 120 may image according to the light collected by the first lens 110, and the camera module is in a normal mode. At this time, in the projection direction along the first lens 110, the projection profile of the first reflection element 130 may be located outside the projection profile of the first lens 110 and outside the projection profile of the first photo sensor chip 120, at this time, the first light blocking surface of the first reflection mirror is not on the light transmission path of the first lens 110, meanwhile, the first reflection surface cannot reflect the light of the second lens 210 to the first photo sensor chip 120, and the light received by the first photo sensor chip 120 is only the light collected by the first lens 110.
At the moment, the user can select the application mode of the camera module according to the actual application scene, so that the application scene of the camera module is further improved.

Based on this, the camera module disclosed in this application further includes a second driving mechanism, the second driving mechanism is in transmission connection with the first reflecting member 130, and the second driving mechanism drives the first reflecting member 130 to rotate. In this embodiment, the second driving mechanism can precisely drive the first reflective member 130 to rotate. Meanwhile, the user can trigger the second driving mechanism to move in a wireless control manner, so as to drive the first reflecting member 130 to rotate, and thus the switching operation of the first reflecting member 130 is more convenient to implement.
