[0002] Electronic devices such as smart phones, tablet computers, and e-readers are usually equipped with camera modules to achieve shooting functions. With the increase in users' demand for photography, camera modules with multiple cameras have emerged. Camera modules have more diverse shooting functions and meet more different shooting needs by setting multiple different types of cameras. However, the size of traditional camera modules with multiple cameras is too large, which is not conducive to the assembly of camera modules in electronic devices. Summary of the invention

[0035] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of the camera module 10 in some embodiments, Figure 2 Schematic diagram of the structure of the electronic device 20 in some embodiments. The electronic device 20 provided in the present application includes but is not limited to a smart phone, a tablet computer, an e-reader, etc. In each embodiment of the present application, a smart phone is taken as an example, and the camera module 10 is provided in the electronic device 20 so that the electronic device 20 has a shooting function.

[0036] In some embodiments, the camera module 10 includes an optical transmission component 11, a first camera 12, a second camera 13 and a third camera 14. The optical transmission component 11 has a first reflective surface 1111, a second reflective surface 1114 and a semi-transparent and semi-reflective surface 1121. The first reflective surface 1111 and the second reflective surface 1114 are arranged back to back. The first reflective surface 1111 and the second reflective surface 1114 can both reflect at least part of the light. The reflectivity of the first reflective surface 1111 and the second reflective surface 1114 to the light can be greater than 60%, 70% or 80%, etc., and can be specifically designed according to shooting requirements. The semi-transparent and semi-reflective surface 1121 can transmit part of the light that hits the semi-transparent and semi-reflective surface 1121, and reflect part of the light that hits the semi-transparent and semi-reflective surface 1121. The transmittance and reflectance of the semi-transparent and semi-reflective surface 1121 are not limited, and can be specifically designed according to shooting requirements. For example, the transmittance and reflectance of the semi-transparent and semi-reflective surface 1121 can be between 30% and 60%.

[0037] In some embodiments, the optical transmission component 11 is used to transmit at least part of the light incident on the first reflective surface 1111, partially after being reflected by the first reflective surface 1111 and the semi-transparent semi-reflective surface 1121, and partially after being reflected by the first reflective surface 1111 and transmitted by the semi-transparent semi-reflective surface 1121. The optical transmission component 11 is also used to transmit at least part of the light incident on the second reflective surface 1114 after being reflected by the second reflective surface 1111. The first camera 12 is used to receive the light passing through the semi-transparent semi-reflective surface 1121, the second camera 13 is used to receive the light reflected by the semi-transparent semi-reflective surface 1121, and the third camera 14 is used to receive the light reflected by the other side of the second reflective surface 1111. In other words, the optical transmission component 11 can transmit at least part of the light received by the first reflective surface 1111 and the second reflective surface 1114, which are disposed opposite to each other, to the first camera 12, the second camera 13, and the third camera 14, respectively. The optical transmission component 11 is provided to simultaneously meet the imaging requirements of the first camera 12 , the second camera 13 and the third camera 14 , thereby realizing the integrated design of the first camera 12 , the second camera 13 and the third camera 14 .

[0038] Combination Figure 1 , Figure 2 and Figure 3As shown, it can be understood that the electronic device 20 is usually provided with a front camera and a rear camera to meet different shooting needs, and the two opposite sides of the shell 21 of the electronic device 20 are usually provided with a front light inlet and a rear light inlet to meet the needs of the front camera and the rear camera to receive light respectively. For example, in some embodiments of the present application, the electronic device 20 includes a shell 21 and a display module 22, and the display module 22 is provided on one side of the shell 21, and a first light inlet 211 is provided on the side of the shell 21 facing away from the display module 22, and a second light inlet 212 is provided on the side of the shell 21 facing the same direction as the display module 22. The first light inlet 211 can be the rear light inlet of the electronic device 20, and the second light inlet 212 can be the front light inlet of the electronic device 20. It should be noted that in Figure 2 In the illustrated embodiment, the display module 22 only covers a portion of one side of the housing 21, the second light inlet 212 is disposed outside the display module 22, and the electronic device 20 may be a notch screen or a water drop screen device. In other embodiments, the electronic device 20 may also be a full-screen device or a curved screen device, and the second light inlet 212 may also be built under the display module 22. The types of the display module 22 and the electronic device 20 are not limited in this application.

[0039] In some embodiments, the optical transmission component 11 is used to receive light incident from the first light inlet 211 through the first reflective surface 1111 and reflect the light to the semi-transparent semi-reflective surface 1121 through the first reflective surface 1111. In other words, part of the light incident from the first light inlet 211 can be sequentially reflected by the first reflective surface 1111 and transmitted by the semi-transparent semi-reflective surface 1121 and transmitted to the first camera 12, and another part of the light can be sequentially reflected by the first reflective surface 1111 and reflected by the semi-transparent semi-reflective surface 1121 and transmitted to the second camera 13. Due to the configuration of the optical transmission component 11, the first light inlet 211 can simultaneously meet the imaging requirements of the first camera 12 and the second camera 13. In some embodiments, the first camera 12 and the second camera 13 can both be rear cameras of the electronic device 20. In some embodiments, the optical transmission component 11 is further used to receive at least part of the light incident from the second light inlet 212 through the second light reflecting surface 1114. In other words, at least part of the light incident from the second light inlet 212 can be reflected by the second light reflecting surface 1114 and transmitted to the third camera 14. The second light inlet 212 can meet the imaging requirements of the third camera 14. In some embodiments, the third camera 14 can be a front camera of the electronic device 20.

[0040] The above-mentioned camera module 10, through the light transmission effect of the optical transmission component 11, enables the camera module 10 to transmit the first reflecting surface 1111 and the second reflecting surface 1114 arranged opposite to each other, for example, the light received by the first light inlet 211 and the second light inlet 212 arranged opposite to each other of the electronic device 20 to the first camera 12, the second camera 13 and the third camera 14 respectively. While three cameras are set to meet different shooting requirements, the three cameras can also share one optical transmission component 11 to realize the integration of the three cameras, thereby reducing the size of the camera module 10, which is beneficial to reducing the size of the electronic device 20 and facilitating the assembly of the camera module 10 in the electronic device 20. In addition, the camera module 10 receives light through the first reflective surface 1111 and the second reflective surface 1114 disposed opposite to each other, and can adapt to the structural design of the front light inlet and the rear light inlet of the electronic device 20. While realizing the integration of three cameras, the third camera 14 can also be used as the front camera of the electronic device 20, and the first camera 12 and the second camera 13 can be used as the rear camera of the electronic device 20, so as to meet the shooting requirements of the front camera and the rear camera of the electronic device 20. It can be understood that the shooting type requirements of the rear camera of the electronic device 20 are usually more than the front camera. The camera module 10 provided in the present application can make the first camera 12 and the second camera 13 serve as the rear camera of the electronic device 20 through the design of the optical transmission component 11 and the corresponding relationship between the optical transmission component 11 and the first light inlet 211 and the second light inlet 212. The first camera 12 and the second camera 13 can use two different types of cameras, thereby meeting more shooting requirements of the rear camera of the electronic device 20.

[0041] In some embodiments, the first reflective surface 1111 and the second reflective surface 1114 are parallel to each other, the first reflective surface 1111 and the second reflective surface 1114 are inclined or perpendicular to the semi-transparent and semi-reflective surface 1121, and the first camera 12 and the third camera 14 are arranged on opposite sides of the optical transmission component 11. For example, in some embodiments, the first reflective surface 1111 and the second reflective surface 1114 are substantially perpendicular to the semi-transparent and semi-reflective surface 1121, the axes of the first light inlet 211 and the second light inlet 212 are substantially coincident, the axes of the first light inlet 211 and the second light inlet 212 are both at an angle of 45° with the first reflective surface 1111 and the second reflective surface 1114, the axes of the first camera 12 and the third camera 14 are both at an angle of 45° with the first reflective surface 1111, the second reflective surface 1114 and the semi-transparent and semi-reflective surface 1121, and the axes of the first camera 12 and the third camera 14 are substantially coincident. The second camera 13 is arranged on the side of the semi-transparent and semi-reflective surface 1121 facing away from the first camera 12, and the axis of the second camera 13 may also form an angle of 45° with the semi-transparent and semi-reflective surface 1121. In this way, the assembly accuracy between the three cameras can be improved through the assembly relationship between the three cameras and the optical transmission component 11, and the assembly accuracy between the housing 21 and the camera module 10 as a whole can be improved through the assembly relationship between the optical transmission component 11 and the first light inlet 211 and the second light inlet 212 of the housing 21, which can effectively improve the assembly accuracy between the components of the camera module 10 and the housing 21, and improve the imaging quality of the camera module 10. At the same time, the optical transmission component 11, the first camera 12 and the second camera 13 at least partially overlap in height in the thickness direction of the electronic device 20, which can effectively reduce the thickness of the camera module 10 on the electronic device 20, which is conducive to compressing the thickness of the electronic device 20 and facilitating the assembly of the camera module 10 in the electronic device 20.

[0042] It can be understood that the first camera 12 and the third camera 14 can be set to have a longer focal length than the second camera 13, and the second camera 13 can be set to have a shorter focal length than the first camera 12 and the third camera 14. While setting different types of cameras to meet different shooting requirements, the size of the camera module 10 in the height direction of the electronic device 20 can be further compressed.

[0043] The specific configuration of the optical transmission component 11 is not limited, as long as the light incident from the first light inlet 211 and the second light inlet 212 can be correspondingly transmitted to the three cameras. The following is an example of some embodiments of the optical transmission component 11. In some embodiments, the optical transmission component 11 includes a first prism 111 and a second prism 112. The first light reflecting surface 1111 and the second light reflecting surface 1114 are disposed on the same surface of the first prism 111. For example, a reflective film layer is coated on the first prism 111, and the two opposite surfaces of the reflective film layer respectively form the first light reflecting surface 1111 and the second light reflecting surface 1114. The semi-transparent and semi-reflective surface 1121 is disposed on the second prism 112. The first prism 111 also includes a first light incident surface 1112 and a first light emitting surface 1113. The second prism 112 also includes a second light incident surface 1122 and a second light emitting surface 1123. The first prism 111 is used to reflect the light received by the first light incident surface 1112 via the first light reflecting surface 1111 and emit it from the first light emitting surface 1113. The second prism 112 is used to receive the light emitted from the first light emitting surface 1113 through the second light incident surface 1122, and can emit part of the light from the second light emitting surface 1123 after being reflected by the semi-transparent and semi-reflective surface 1121, and emit part of the light from the second light emitting surface 1123 after being transmitted through the semi-transparent and semi-reflective surface 1121.

[0044] In some embodiments, the first camera 12 is disposed on the side where the semi-transparent and semi-reflective surface 1121 of the second prism 112 is located, that is, the side of the semi-transparent and semi-reflective surface 1121 facing away from the first reflective surface 1111, the second camera 13 is disposed on the side where the second light emitting surface 1123 of the second prism 112 is located, and the third camera 14 is disposed on the side where the second reflective surface 1111 of the first prism 111 is located.

[0045] It can be understood that at least part of the light incident from the first light inlet 211 can pass through the first light incident surface 1112 and be reflected on the first light reflecting surface 1111 to be incident on the semi-transparent and semi-reflective surface 1121, part of the light incident on the semi-transparent and semi-reflective surface 1121 is reflected by the semi-transparent and semi-reflective surface 1121 and passes through the second light emitting surface 1123 to reach the second camera 13, and another part of the light incident on the semi-transparent and semi-reflective surface 1121 passes through the semi-transparent and semi-reflective surface 1121 to be incident on the first camera 12. At least part of the light incident from the second light inlet 212 can be incident on the second light reflecting surface 1114, and is reflected by the second light reflecting surface 1114 to be incident on the third camera 14. In some embodiments, the optical path of the imaging light corresponding to the first camera 12 and the second camera 13 is deflected 90° at the first reflective surface 1111, the optical path of the imaging light corresponding to the second camera 13 is deflected 90° at the semi-transparent semi-reflective surface 1121, and the optical path of the imaging light corresponding to the third camera 14 is deflected 90° at the second reflective surface 1114. Through the design of the deflection effect of the first reflective surface 1111, the second reflective surface 1114 and the semi-transparent semi-reflective surface 1121 on the light, the positions of the three cameras relative to the optical transmission component 11 can be reasonably set, thereby improving the assembly accuracy of the camera module 10 and compressing the size of the camera module 10.

[0046] In some embodiments, the first light emitting surface 1113 and the second light incident surface 1122 are in contact with each other, and the first light incident surface 1112 and the second light emitting surface 1123 are flush, which is beneficial for improving the alignment accuracy of the first prism 111 and the second prism 112, and is also beneficial for compressing the overall occupied space of the optical transmission component 11, thereby compressing the size of the camera module 10.

[0047] In some embodiments, the first prism 111 and the second prism 112 can both be right-angle prisms, the two right-angle surfaces of the first prism 111 are respectively a first light incident surface 1112 and a first light emitting surface 1113, the inclined surface is coated with a reflective film layer, and the two opposite sides of the reflective film layer form a first light reflecting surface 1111 and a second light reflecting surface 1114, respectively; the two right-angle surfaces of the second prism 112 are respectively a second light incident surface 1122 and a second light emitting surface 1123, and the inclined surface is coated with a semi-transparent and semi-reflective film layer to form a semi-transparent and semi-reflective surface 1121.

[0048] Combination Figure 1 and Figure 4As shown, in other embodiments, the first prism 111 may be replaced by a reflector 113, and the first reflective surface 1111 and the second reflective surface 1114 may be respectively arranged on opposite sides of the reflector 113, and the light incident from one of the first light inlet 211 and the second light inlet 212 hits the first reflective surface 1111 and is reflected from the first reflective surface 1111, and the light incident from the other hits the second reflective surface 1114 and is reflected from the second reflective surface 1114 and hits the third camera 14. In other embodiments, the second prism 112 may be replaced by a flat glass (not shown), and a semi-transparent and semi-reflective film layer is provided on one surface of the flat glass to form a semi-transparent and semi-reflective surface 1121.

[0049] In some embodiments, the first camera 12 includes a first lens group 121 and a first image sensor 122, the second camera 13 includes a second lens group 131 and a second image sensor 132, and the third camera 14 includes a third lens group 141 and a third image sensor 142. The first lens group 121, the second lens group 131, and the third lens group 141 each include at least one glass or plastic lens with optical power. The light received by the three cameras can be irradiated to the corresponding image sensor after being adjusted by the corresponding lens group, which is conducive to improving the imaging quality of the three cameras. It should be noted that the axes of the first camera 12, the second camera 13, and the third camera 14 can be understood as the axes of the corresponding lens groups.

[0050] In some embodiments, the optical transmission component 11 further includes a first lens 114 having optical focal length, and the first lens 114 is disposed on the first light incident surface 1112. The light incident from the first light inlet 211 is regulated by the first lens 114 and then passes through the first light incident surface 1112 to be emitted to the first light reflecting surface 1111. In other words, the light received by the first camera 12 and the second camera 13 is regulated by the first lens 114. The first lens 114 is provided in the optical transmission component 11 to regulate the light, which can reduce the burden of regulating the light by the first lens group 121 of the first camera 12 and the second lens group 131 of the second camera 13, thereby making full use of the spatial layout of the camera module 10, and facilitating the reduction of the number of lenses in the first lens group 121 and the second lens group 131, and compressing the axial dimensions of the first camera 12 and the second camera 13, thereby compressing the size of the camera module 10.

[0051] In some embodiments, the optical transmission component 11 further includes a second lens 115, which is disposed on the second light exiting surface 1123 and opposite to the second camera 13. The light received by the second camera 13 can be adjusted by the second lens 115, and cooperate with the first lens 114, which is conducive to further reducing the burden of adjusting the light of the second lens group 131, thereby facilitating reducing the number of lenses of the second lens group 131 and compressing the axial size of the second camera 13. When the axial direction of the second camera 13 corresponds to the thickness direction of the electronic device 20, such a design can also effectively compress the size of the camera module 10 in the thickness direction of the electronic device 20. At the same time, when the first light incident surface 1112 and the second light exiting surface 1123 are flush, the heights of the first lens 114 and the second lens 115 in the thickness direction of the electronic device 20 at least partially overlap, and the size of the camera module 10 in the thickness direction of the electronic device 20 can be further compressed while adjusting the light.

[0052] In some embodiments, the first lens 114 has a positive focal length, which is conducive to converging light and compressing the total length of the light path passing through the first lens 114, thereby facilitating the compression of the axial dimensions of the first lens group 121 and the second lens group 131. In some embodiments, the second lens 115 has a positive focal length, which is conducive to further converging light and compressing the axial dimension of the second camera 13, thereby compressing the dimension of the camera module 10 in the thickness direction of the electronic device 20. Of course, according to different imaging requirements, the first lens 114 and the second lens 115 can also have negative focal lengths.

[0053] In some embodiments, the first lens group 121 includes five plastic or glass lenses with optical power arranged in sequence in the direction from the semi-transparent and semi-reflective surface 1121 to the first image sensor 122 along the optical path, the second lens group 131 includes a plastic or glass lens with positive optical power, and the third lens group 141 includes five glass or plastic lenses with optical power arranged in sequence in the direction from the second reflective surface 1114 to the third image sensor 142 along the optical path. In this embodiment, through the design of the optical transmission component 11 to deflect the optical path, the axes of the first camera 12 and the third camera 14 with more lenses and longer axial dimensions are perpendicular to the axes of the first light inlet 211 and the second light inlet 212, and the axis of the second camera 13 with fewer lenses and shorter axial dimensions is parallel to the axes of the first light inlet 211 and the second light inlet 212. At the same time, the axial dimension of the second camera 13 is further compressed in conjunction with the design of the first lens 114 and the second lens 115, which can effectively compress the dimension of the camera module 10 in the thickness direction of the electronic device 20. Of course, according to different shooting requirements of different types of cameras, the number of lenses and the combination of optical focal lengths of the lenses in the first lens group 121, the second lens group 131 and the third lens group 141 can also have any other applicable designs, which will not be elaborated in this application.

[0054] It is understandable that, since the first camera 12 and the second camera 13 are both disposed adjacent to the second prism 112, in some embodiments, the first camera 12, the second camera 13 and the optical transmission component 11 can all be fixedly disposed on the same bracket (not shown), which is conducive to improving the assembly accuracy of the optical transmission component 11, the first camera 12 and the second camera 13, thereby improving the imaging quality of the camera module 10. Of course, in some embodiments, the first camera 12, the second camera 13, the third camera 14 and the optical transmission component 11 can all be fixedly disposed on the same bracket, which is conducive to improving the assembly accuracy between the components of the camera module 10, and avoiding the situation where different cameras are separately disposed and the accuracy is reduced.

[0055] In some embodiments, the first image sensor 122 may be a visible light image sensor, and the first camera 12 may be a camera capable of capturing visible light, the second image sensor 132 may be an infrared image sensor, and the second camera 13 may be a camera capable of capturing infrared light, and the third image sensor 142 may be an ultraviolet light sensor, and the third camera 14 may be a camera capable of capturing ultraviolet light. Setting the three cameras as different types of cameras can meet different shooting requirements and improve the user experience of the camera module 10.

[0056] For example, in some embodiments, the focal length of the first lens group 121 is greater than the focal lengths of the second lens group 131 and the third lens group 141, and the first camera 12 can be a telephoto camera, which can meet the requirements of capturing images of distant objects. The second camera 13 can use infrared light to achieve infrared imaging in low-light environments such as nighttime, or achieve distance measurement and other functions through infrared imaging. The third camera 14 can monitor the intensity of ultraviolet light through ultraviolet imaging, thereby performing a sunscreen reminder function. For example, in some embodiments, the electronic device 20 also includes a second control element 23, which is used to control the display module 22 to issue a sunscreen reminder message according to the ultraviolet light intensity sensed by the third image sensor 142, or adjust the sunscreen reminder message issued by the display module 22. Specifically, the second light inlet 212 of the electronic device 20 can be oriented toward the user to sense the intensity of the ultraviolet light reflected by the user's skin. When the intensity of the ultraviolet light reflected by the user is greater than the threshold, the second control element 23 can control the display module 22 to display the sunscreen reminder information in the display interface to remind the user to apply sunscreen or perform other sunscreen work. When the intensity of the ultraviolet light sensed by the third image sensor 142 changes, the second control element 23 can also control the sunscreen reminder signal displayed by the display module 22 to change, and remind the user whether the sunscreen work is in place through different sunscreen reminder signals. Among them, the setting of the threshold is not limited, and can be set according to the user's sunscreen needs. It is not limited in this application. The type of sunscreen reminder signal is also not limited, as long as the user can know the ultraviolet light intensity. For example, the display module 22 can directly display the ultraviolet light intensity value sensed by the third image sensor 142 to form a sunscreen reminder signal. Of course, the electronic device 20 can also generate a sunscreen reminder signal through other modules, as long as the user can obtain the sunscreen reminder signal, for example, a sound reminder is issued through a speaker to form a sunscreen reminder signal.

[0057] In some embodiments, at least one lens in the first lens group 121 can cut off infrared light and ultraviolet light. For example, the material of at least one lens in the first lens group 121 includes infrared light and ultraviolet light cutting material, or the surface of at least one lens is coated with an infrared light and ultraviolet light cutting film. The transmittance of the lens for cutting off infrared light and ultraviolet light in the first lens group 121 for light of different wavelengths can be referred to Figure 5 As shown, the transmittance of the lens to infrared light with a wavelength greater than 710nm and ultraviolet light with a wavelength less than 400nm can be less than or equal to 1%, which can effectively cut off infrared light and ultraviolet light to prevent infrared light and ultraviolet light from reaching the first image sensor 122 and affecting the imaging quality of visible light.

[0058] In some embodiments, at least one lens in the second lens group 131 can cut off visible light and ultraviolet light. For example, the material of at least one lens in the second lens group 131 includes visible light and ultraviolet light cutting material, or the surface of at least one lens is coated with a visible light and ultraviolet light cutting film. The transmittance of the lens for cutting off visible light and ultraviolet light in the second lens group 131 for light of different wavelengths can be referred to Figure 6 As shown, the transmittance of the lens to infrared light with a wavelength greater than 710nm is greater than or equal to 50%, and the transmittance to visible light and ultraviolet light with a wavelength less than 710nm can be less than or equal to 1%, which can effectively cut off visible light and ultraviolet light, and transmit infrared light, thereby improving the imaging quality of infrared light by the second camera 13. Of course, since the light received by the second camera 13 is adjusted by the second lens 115, in other embodiments, the second lens 115 can cut off visible light and ultraviolet light, or the second lens 115 and at least one lens in the second lens group 131 can cut off visible light and ultraviolet light.

[0059] In some embodiments, at least one lens in the third lens group 141 can cut off visible light and infrared light. For example, the material of at least one lens in the third lens group 141 includes visible light and infrared light cutting material, or the surface of at least one lens is coated with a visible light and infrared light cutting film. The transmittance of the lens for cutting off visible light and ultraviolet light in the third lens group 141 for light of different wavelengths can be referred to. Figure 7 As shown, the transmittance of the lens to ultraviolet light with a wavelength between 300nm-400nm is greater than or equal to 50%, and the transmittance to visible light and infrared light with a wavelength greater than 400nm can be less than or equal to 1%. It can effectively cut off visible light and infrared light, and transmit ultraviolet light, thereby improving the imaging quality of the third camera 14 to ultraviolet light.

[0060] Of course, the cut-off wavelength range of the lens used to cut off part of the light in the camera module 10 and the transmittance of various wavelengths are not limited to Figure 5-Figure 7 As shown, according to different shooting requirements, the wavelength-transmittance curve of the lens can also have other settings, which will not be repeated in this application. It can be understood that by making the material of the lens in the camera module 10 have a partial light cutoff material, or coating the surface of the lens with a film layer having a partial light cutoff effect, the camera module 10 does not need to additionally set up a partial light cutoff filter or other filter elements to realize visible light imaging, ultraviolet light imaging and infrared light imaging respectively, which can further compress the size of the camera module 10.

[0061] Combination Figure 8 and Fig. 9As shown, in some embodiments, when the first camera 12 is a telephoto camera, for example, the focal length of the first lens group 121 is greater than the focal lengths of the second lens group 131 and the third lens group 141, the first camera 12 further includes a third prism 123, and the third prism 123 is disposed between the first lens group 121 and the first image sensor 122 along the optical path, and the third prism 123 can deflect the optical path so that the axis of the first image sensor 122 is inclined or perpendicular to the axis of the first lens group 121. It can be understood that when the first camera 12 is a telephoto camera, the axial dimension of the first camera 12 is longer than the axial dimensions of the first camera 12 and the second camera 13, and the third prism 123 is disposed between the first lens group 121 and the first image sensor 122 to deflect the optical path, so as to compress the dimension of the third camera 14 in the direction perpendicular to the thickness of the electronic device 20, which is conducive to the assembly of the camera module 10 in the electronic device 20.

[0062] refer to Figure 8 As shown, in some embodiments, the first prism 111 is a right-angle prism, and the reflection of the right-angle surface of the first prism 111 can deflect the light path emitted from the first lens group 121 by 90°, so that the photosensitive surface of the first image sensor 122 is parallel to the axis of the first lens group 121, which can effectively compress the size of the camera module 10 in a direction perpendicular to the thickness of the electronic device 20. In some embodiments, the third prism 123 deflects the light path toward the side away from the second camera 13, so that the first image sensor 122 is arranged on the side of the third prism 123 away from the second camera 13.

[0063] refer to Fig. 9 As shown, in other embodiments, the third prism 123 deflects the light path emitted from the first lens group 121 toward the direction close to the second camera 13, so that the second camera 13 and the first image sensor 122 are located on the same side of the second prism 112 and the third prism 123. For example, the third prism 123 has a third light-emitting surface 1231 opposite to the first image sensor 122, and the second light-emitting surface 1123 and the third light-emitting surface 1231 face the same side, so that the height of the first image sensor 122 in the thickness direction of the electronic device 20 at least partially overlaps with the second lens 115 or the second camera 13. Therefore, while the third prism 123 is provided to reduce the size of the camera module 10 in the direction perpendicular to the thickness of the electronic device 20, the deflection of the light path in the first camera 12 will not increase the size of the camera module 10 in the thickness direction of the electronic device 20, which is conducive to compressing the size of the camera module 10 in the thickness direction of the electronic device 20, facilitating the assembly of the camera module 10 in the electronic device 20, and also facilitating reducing the thickness of the electronic device 20. Of course, the third prism 123 is a right-angle prism, and may also be any other suitable optical element such as a plane reflective element, as long as it can deflect the light path of the first camera 12 by reflection.

[0064] It is understandable that the components in the first camera 12 may expand and contract with the change of temperature, resulting in the change of the back focal length of the first lens group 121, that is, the shortest distance between the first lens group 121 and the first image sensor 122, which may easily lead to a decrease in the focusing accuracy between the first lens group 121 and the first image sensor 122, affecting the imaging quality of the first camera 12. For example, referring to the following Table 1, Figure 1 The relationship between the back focal length of the first lens group 121 and the temperature is shown. It can be seen from Table 1 that when the temperature is 25°, the thermal expansion and contraction effect of the first lens group 121 is not obvious, and the back focal length of the first lens group 121 is in an ideal state. When the temperature is lower than 25°, the thermal expansion and contraction effect of the first lens group 121 will cause the back focal length of the first lens group 121 to shorten, and the lower the temperature, the greater the shortening displacement of the back focal length. When the temperature is higher than 25°, the back focal length of the first lens group 121 increases, and the higher the temperature, the greater the increase displacement of the back focal length.

[0065]

[0066]

[0067] In order to avoid the change of back focal length caused by the thermal expansion and contraction effect of the components and reduce the imaging quality of the first camera 12, refer to Fig.10 As shown, in some embodiments, the camera module 10 further includes a temperature sensor 15, a first control element 16, and a driving element 17. The temperature sensor 15 is used to sense the temperature of the camera module 10, for example, to sense the temperature at the first camera 12. The first control element 16 is used to control the driving element 17 to drive the first lens group 121 and the first image sensor 122 to move relative to each other according to the temperature sensed by the temperature sensor 15. For example, the first control element 16 may pre-store a corresponding relationship between the back focal length change and the temperature change of the first lens group 121, specifically referring to Table 1, the first control element 16 may obtain the temperature value sensed by the temperature sensor 15, and according to the pre-stored corresponding relationship between the back focal length change and the temperature change, obtain the change value of the back focal length at the temperature, and drive the first lens group 121 and the first image sensor 122 to move to compensate for the change value. For example, when the temperature value sensed by the temperature sensor 15 is 35°C, it can be learned from the pre-stored corresponding relationship that due to the thermal expansion and contraction effect, the shortest distance between the first lens group 121 and the first image sensor 122 increases by 0.04 mm corresponding to 25°C. The first control element 16 can control the driving element 17 to drive the first lens group 121 and the first image sensor 122 to be relatively close to each other by 0.04 mm to compensate for the change in back focal length caused by temperature change, thereby improving the focusing accuracy of the first lens group 121 and the first image sensor 122 and improving the imaging quality of the first camera 12.

[0068] The specific arrangement of the temperature sensor 15 is not limited. In some embodiments, the side wall of the lens barrel accommodating the first camera 12 may be provided with a groove, and the temperature sensor 15 may be provided in the groove of the lens barrel of the first camera 12, which can effectively sense the temperature of the first camera 12 without increasing the size of the camera module 10. The driving element 17 drives the first lens group 121 and the first image sensor 122 to move relative to each other, including but not limited to driving the first lens group 121 to move relative to the first image sensor 122, or driving the first image sensor 122 to move relative to the first lens group 121. The driving element 17 includes but is not limited to any applicable element capable of driving the first lens group 121 or the first image sensor 122 to move, such as a voice coil motor.

[0069] It should be noted that, in the present application, the first control element 16 and the second control element 23 can both be components in the central processing unit of the electronic device 20, the first control element 16 can also be a chip in the camera module 10 specifically used to compensate for the change in rear focal length, and the second control element 23 can also be a chip in the electronic device 20 specifically used to control the sun protection reminder information according to the intensity of ultraviolet light.

[0070] It should be noted that the number of cameras in the camera module 10 provided in the present application is not limited to three. Depending on different shooting requirements, the camera module 10 may also include four, five or other numbers of cameras, and a larger number of prisms and other optical transmission elements may be correspondingly arranged in the optical transmission component 11. As long as the light incident from the first light inlet 211 and the second light inlet 212 can be respectively transmitted to each camera through the optical transmission component 11 to realize the integration of multiple cameras, the specific design of the optical transmission component 11 and the optical path design can be set according to the number and position of the cameras, and will not be repeated in this application.

[0071] refer to Fig.11 , Fig.11 The electronic device 10 is a schematic diagram of the structure of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may include a radio frequency (RF) circuit 501, a memory 502 including one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless fidelity (WiFi) module 507, a processor 508 including one or more processing cores, and a power supply 509. Those skilled in the art will understand that Fig.11 The structure of the electronic device 10 shown in the figure does not constitute a limitation on the electronic device 10, and the electronic device 10 may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0072] The radio frequency circuit 501 can be used to send and receive information, or receive and send signals during a call. In particular, after receiving the downlink information of the base station, it is handed over to one or more processors 508 for processing; in addition, the data related to the uplink is sent to the base station. Usually, the radio frequency circuit 501 includes but is not limited to an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the radio frequency circuit 501 can also communicate with the network and other devices through wireless communication.

[0073] The memory 502 can be used to store applications and data. The applications stored in the memory 502 contain executable codes. The applications can be composed of various functional modules. The processor 508 executes various functional applications and data processing by running the applications stored in the memory 502. The memory 502 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the electronic device 10 (such as audio data, a phone book, etc.), etc. In addition, the memory 502 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory 502 can also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0074] The input unit 503 can be used to receive input digital, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display screen or a touch pad, can collect user touch operations on or near it (such as operations performed by users using fingers, styluses, or any other suitable objects or accessories on or near the touch-sensitive surface), and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508.

[0075] The display unit 504 can be used to display information input by the user or information provided to the user and various graphical user interfaces of the electronic device 10, which can be composed of graphics, text, icons, videos and any combination thereof. The display unit 504 may include a display panel. Optionally, the display panel can be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like. Furthermore, the touch-sensitive surface may cover the display panel, and when the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor 508 to determine the type of touch event, and then the processor 508 provides a corresponding visual output on the display panel according to the type of touch event. Although in Fig.11 In the embodiment, the touch sensitive surface and the display panel are used as two independent components to implement input and output functions, but in some embodiments, the touch sensitive surface and the display panel can be integrated to implement input and output functions. It can be understood that the display screen 110 can include an input unit 503 and a display unit 504.

[0076] The electronic device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel according to the brightness of the ambient light, and the proximity sensor may turn off the display panel and / or backlight when the electronic device 10 is moved to the ear. As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in each direction (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that the electronic device 10 can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0077] The audio circuit 506 can provide an audio interface between the user and the electronic device 10 through a speaker and a microphone. The audio circuit 506 can convert the received audio data into an electrical signal, transmit it to the speaker, and convert it into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 506 and converted into audio data, and then the audio data is output to the processor 508 for processing, and then sent to another electronic device 10 through the radio frequency circuit 501, or the audio data is output to the memory 502 for further processing. The audio circuit 506 may also include an earphone socket to provide communication between an external earphone and the electronic device 10.

[0078] Wireless Fidelity (WiFi) is a short-range wireless transmission technology. The electronic device 10 can help users send and receive emails, browse web pages, and access streaming media through the wireless fidelity module 507, which provides users with wireless broadband Internet access. Fig.11 The wireless fidelity module 507 is shown, but it is understandable that it is not a necessary component of the electronic device 10 and can be omitted as needed without changing the essence of the invention.

[0079] The processor 508 is the control center of the electronic device 10. It uses various interfaces and lines to connect various parts of the entire electronic device 10. By running or executing applications stored in the memory 502 and calling data stored in the memory 502, it executes various functions of the electronic device 10 and processes data, thereby monitoring the electronic device 10 as a whole. Optionally, the processor 508 may include one or more processing cores; preferably, the processor 508 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 508.

[0080] The electronic device 10 also includes a power supply 509 for supplying power to various components. Preferably, the power supply 509 can be logically connected to the processor 508 through a power management system, so that the power management system can manage charging, discharging, and power consumption. The power supply 509 can also include one or more DC or AC power supplies, recharging systems, power failure detection circuits, power converters or inverters, power status indicators, and other arbitrary components.

[0081] although Fig.11 Not shown, the electronic device 10 may also include a Bluetooth module, etc., which will not be described in detail here. In specific implementation, the above modules can be implemented as independent entities, or can be arbitrarily combined and implemented as the same or several entities. The specific implementation of the above modules can refer to the previous method embodiment, which will not be described in detail here.

[0082] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
