Description

Technical Field

[0001] This application relates to the field of optical technology, specifically to an optical lens, a camera module, and an electronic device. Background Technology

[0002] Using a large image sensor can increase the image area and improve imaging quality. However, the internal space of electronic devices is limited, and with the increasing thinness, miniaturization, and multifunctionality of electronic devices, it is difficult to reserve a large space for a large image sensor. Therefore, how to match the optical lens in the camera module of an electronic device with a suitable image sensor size while ensuring that the imaging quality meets the design requirements has become a technical problem that needs to be solved. Summary of the Invention

[0003] This application provides an optical lens, camera module, and electronic device that can balance imaging performance and design size.

[0004] On one hand, this application provides an optical lens, comprising:

[0005] Reflector;

[0006] Deformable lens group; and

[0007] The corrective lens group is arranged sequentially between the reflector and the image plane, such that light rays from the object plane pass sequentially through the reflector, the deformable lens group, and the corrective lens group to the image plane; or, the deformable lens group is located between the reflector and the object plane, and the corrective lens group is located between the reflector and the image plane, such that light rays from the object plane pass sequentially through the deformable lens group, the reflector, and the corrective lens group to the image plane.

[0008] Wherein, the optical power of the deformable lens group along the horizontal meridian and the optical power of the corrective lens group along the horizontal meridian are either positive or negative, and the radius of curvature of the deformable lens group along the horizontal meridian is different from that of the corrective lens group along the horizontal meridian; and / or, the optical power of the deformable lens group along the vertical meridian and the optical power of the corrective lens group along the vertical meridian are either positive or negative, and the radius of curvature of the deformable lens group along the vertical meridian is different from that of the corrective lens group along the vertical meridian.

[0009] On the other hand, this application also provides a camera module, including an image sensor and the aforementioned optical lens. At least one of the reflector, the anamorphic lens group, and the corrective lens group, and the image sensor are arranged sequentially such that light from the object surface passes sequentially through the reflector and the corrective lens group onto the image sensor. The surface of the image sensor facing the reflector forms the image plane. The extension dimension of the image sensor along a first extension direction is different from the extension dimension of the image sensor along a second extension direction. The first extension direction is parallel to the horizontal meridian of at least one of the anamorphic lens group and the corrective lens group, and the second extension direction is parallel to the vertical meridian of at least one of the anamorphic lens group and the corrective lens group.

[0010] In another aspect, this application also provides an electronic device, including an image processor and the aforementioned camera module, wherein the image processor is electrically connected to the image sensor, and the image processor is used to acquire the image generated by the image sensor and to scale the image in the first extension direction and / or the second extension direction.

[0011] The optical lens provided in this application includes a reflector and a functional lens assembly. The functional lens assembly includes an anamorphic lens group and a corrective lens group. When one of the optical power of the anamorphic lens group and the optical power of the corrective lens group in the horizontal meridian is positive and the other is negative, and the radius of curvature of the anamorphic lens group in the horizontal meridian is different from that of the corrective lens group in the horizontal meridian, the optical lens can achieve the convergence or divergence of light in the horizontal meridian direction. This is beneficial for compressing or enlarging the size of the image sensor of the camera module in that direction, so as to balance the imaging effect and size of the camera module. When one of the optical power of the anamorphic lens group and the optical power of the corrective lens group along the vertical meridian is positive and the other is negative, and the radius of curvature of the anamorphic lens group along the vertical meridian is different from that of the corrective lens group, the optical lens can achieve convergence or divergence of light in the vertical meridian direction. This is beneficial for compressing or enlarging the size of the image sensor of the camera module in this direction, so as to balance the imaging effect and size of the camera module. This allows for the matching of a suitable image sensor while ensuring that the imaging effect of the electronic device meets the design requirements, thus facilitating the development of thinner, smaller, and more multifunctional electronic devices.

[0042] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application without creative effort are within the protection scope of this application.

[0043] In this application, the terms "embodiment" and "implementation" mean that a specific feature, structure, or characteristic described in connection with an embodiment or implementation can be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in this application can be combined with other embodiments.

[0044] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of a camera module 100 provided in an embodiment of this application. The electronic device 1000 can be a mobile phone, tablet computer, laptop computer, computer, watch, drone, robot, digital camera, or other device with imaging capabilities. This embodiment uses a mobile phone as an example. The following embodiments are for ease of description and establishment... Figure 1 The coordinate system is described above. The X-axis can be understood as the width direction of the electronic device 1000, the Y-axis as the length direction, and the Z-axis as the thickness direction. The electronic device 1000 includes an image processor 200 and a camera module 100. The camera module 100 includes an image sensor 2 and an optical lens 1. The image sensor 2 receives light transmitted through the optical lens 1 and generates an image. The image sensor 2 can be a CCD image sensor, a CMOS image sensor, etc. The image processor 200 is electrically connected to the image sensor 2. The image processor 200 acquires the image generated by the image sensor 2 and scales the image in a first extension direction and / or a second extension direction. The first and second extension directions are both extension directions of the image plane of the image sensor 2. It is understood that the image generated by the image sensor 2 lies on the plane formed by the first and second extension directions. The first extension direction can be referred to as direction A in the figure, and the second extension direction can be referred to as direction B in the figure. For ease of reference to the figure, the first extension direction will be directly described as the first extension direction A and the second extension direction will be directly described as the second extension direction B in the following description.

[0045] In one optional embodiment, the first extension direction A can be the length direction of the electronic device 1000, and the second extension direction B can be the thickness direction of the electronic device 1000. In this embodiment, the image sensor 2 can generate an image with the first extension direction A and / or the second extension direction B compressed, so as to compress the size of the image sensor 2 along the first extension direction A and / or the second extension direction B, thereby reducing the length of the electronic device 1000, which is beneficial to miniaturization of the electronic device 1000, and / or reducing the thickness of the electronic device 1000, which is beneficial to thinning the electronic device 1000; then the image processor 200 magnifies the image of the first extension direction A and / or the second extension direction B to ensure the imaging effect and capture the image at the required ratio. In addition, when the length and thickness of the electronic device 1000 are large, an image sensor 2 with a larger size in the first extension direction A and / or the second extension direction B can be set to increase the image area and improve the imaging effect.

[0046] In another optional embodiment, the first extension direction A can be the width direction of the electronic device 1000, and the second extension direction B can be the thickness direction of the electronic device 1000. In this embodiment, the image sensor 2 can generate an image with the first extension direction A and / or the second extension direction B compressed, so as to compress the size of the image sensor 2 in the first extension direction A and / or the second extension direction B, thereby reducing the width of the electronic device 1000, which is beneficial to miniaturization of the electronic device 1000, and / or reducing the thickness of the electronic device 1000, which is beneficial to thinning the electronic device 1000; then the image processor 200 enlarges the image in the first extension direction A and / or the second extension direction B to ensure the imaging effect and capture the image at the required ratio. In addition, when the length and thickness of the electronic device 1000 are large, the image sensor 2 with a larger size in the first extension direction A and / or the second extension direction B can be set to increase the image area and improve the imaging effect.

[0047] In other optional embodiments, the first extension direction A can be the length direction of the electronic device 1000, and the second extension direction B can be the width direction of the electronic device 1000; or, the first extension direction A can be the width direction of the electronic device 1000, and the second extension direction B can be the length direction of the electronic device 1000. In this embodiment, the image sensor 2 can also generate an image with the first extension direction A and / or the second extension direction B compressed, so as to compress the size of the image sensor 2 in the first extension direction A and / or the second extension direction B, thereby reducing the width or length of the electronic device 1000, which is beneficial to miniaturization of the electronic device 1000; then the image processor 200 enlarges the image in the first extension direction A and / or the second extension direction B to ensure the imaging effect and capture the image at the required ratio. In addition, when the length and width of the electronic device 1000 are large, an image sensor 2 with a larger size in the first extension direction A and / or the second extension direction B can be set to increase the image area and improve the imaging effect.

[0048] In the following embodiments, unless otherwise specified, the camera module 100 and the optical lens 1 of this application will be described in detail using the first extension direction A as the length direction of the electronic device 1000 and the second extension direction B as the thickness direction of the electronic device 1000 as examples.

[0049] The second extension direction B is the thickness direction of the electronic device 1000, which allows the image sensor 2 to generate an image compressed in the second extension direction B, thereby helping to reduce the thickness of the electronic device 1000. The image processor 200 is used to magnify the image in the second extension direction B. After acquiring the image compressed in the second extension direction B generated by the image sensor 2, the image processor 200 can magnify the image in the second extension direction B to restore the image, thereby realizing real-scene shooting or matching the aspect ratio of the restored image to the size of the display screen of the electronic device 1000. It can be understood that the compression ratio of the compressed image generated by the image sensor 2 in the second extension direction B and the magnification ratio of the image processor 200 in the second extension direction B can be the same or different.

[0050] Optionally, the extension dimension of the image plane along the second extension direction B is greater than or equal to 0.5 times the extension dimension of the image plane along the first extension direction A, and less than or equal to 0.8 times the extension dimension of the image plane along the first extension direction A. By making the extension dimension of the image plane along the second extension direction B greater than or equal to 0.5 times the extension dimension of the image plane along the first extension direction A, and less than or equal to 0.8 times the extension dimension of the image plane along the first extension direction A, the compression ratio of the camera module 100 in the second extension direction B can be greater than or equal to 1.25 and less than or equal to 2. In this case, the size of the image sensor 2 in the second extension direction B and the image restored by the image processor 200 are both better, resulting in a better balance between imaging effect and design size.

[0051] Please refer to Figures 2 to 4 ,in, Figure 3 This is a schematic diagram of the structure of an optical lens 1 provided in an embodiment of this application. Figure 4 This is a schematic diagram of another optical lens 1 provided in an embodiment of this application. The optical lens 1 includes a reflector 10 and a functional lens assembly 11. The optical lens 1 provided in this embodiment is a periscope optical lens 1. Specifically, the optical lens 1 has a first optical axis between the reflector 10 and the object plane, and a second optical axis between the reflector 10 and the image plane, with the first optical axis perpendicular to the second optical axis. The first optical axis can be referenced... Figure 3 , Figure 4 The M-axis and the second optical axis can be referenced in the diagram. Figure 3 , Figure 4 The N-axis in the image. The periscope optical lens 1 helps to increase the focal length of the camera module 100, enabling better capture of distant objects.

[0052] In one optional embodiment, the reflector 10 includes an incident surface 101, a reflecting surface 102, and an exiting surface 103. The incident surface 101 faces the object surface and is used to allow light rays from the object surface to enter. The reflecting surface 102 is used to reflect the light rays entering through the incident surface 101 onto the exiting surface 103. The exiting surface 103 faces the image surface and is used to direct the light rays reflected by the reflecting surface 102 toward the image surface.

[0053] The functional lens assembly 11 includes an anamorphic lens group 110 and a corrective lens group 112. The anamorphic lens group 110 includes one or more anamorphic lenses, which are used to converge or diverge incident light. Specifically, when the optical power of the anamorphic lens group 110 is positive, it is used to converge incident light; when the optical power of the anamorphic lens group 110 is negative, it is used to diverge incident light. In the following embodiments, unless otherwise specified, the anamorphic lens group 110 is assumed to include one anamorphic lens. The corrective lens group 112 includes one or more corrective lenses, which are used to correct aberrations in converged or diverged incident light. In the following embodiments, unless otherwise specified, the corrective lens group 112 is assumed to include one corrective lens. The anamorphic lens group 110 and the corrective lens group 112 are arranged sequentially between the reflecting mirror 10 and the image plane; alternatively, the anamorphic lens group 110 is located between the reflecting mirror 10 and the object plane, and the corrective lens group 112 is located between the reflecting mirror 10 and the image plane. Understandably, in the path of light propagation, the anamorphic lens group 110 is located in front of the corrective lens group 112. In other words, the anamorphic lens group 110 is closer to the object plane than the corrective lens group 112, and the corrective lens group 112 is closer to the image plane than the anamorphic lens group 110.

[0054] The reflector 10, the corrector lens group 112, and the image sensor 2 are arranged sequentially, with the surface of the image sensor 2 facing the reflector 10 forming an image plane. The first extension direction A of the image plane is parallel to the horizontal meridian of the corrector lens group 112, and the second extension direction B of the image plane is parallel to the vertical meridian of the corrector lens group 112. It can be understood that the horizontal meridian of the corrector lens group 112 is along the length of the electronic device 1000, and the vertical meridian of the corrector lens group 112 is along the thickness of the electronic device 1000. A "meridian" refers to the intersection of a cross-section through the optical axis of a lens and the surface of that lens. A horizontal meridian can be understood as the intersection of a horizontal cross-section through the optical axis of a lens and the surface of that lens. A vertical meridian can be understood as the intersection of a vertical cross-section through the optical axis of a lens and the surface of that lens.

[0055] In one alternative embodiment, such as Figure 3As shown, the anamorphic lens group 110 and the corrective lens group 112 are arranged sequentially between the reflecting mirror 10 and the image plane. In other words, the reflecting mirror 10, the anamorphic lens group 110, the corrective lens group 112, and the image plane are arranged sequentially along the direction of light propagation. In this embodiment, the horizontal meridian of the anamorphic lens group 110 is parallel to the horizontal meridian of the corrective lens group 112, and the vertical meridian of the anamorphic lens group 110 is parallel to the vertical meridian of the corrective lens group 112. Specifically, the horizontal meridians of the anamorphic lens group 110 and the horizontal meridians of the corrective lens group 112 can both be parallel to the Y-axis direction; the vertical meridians of the anamorphic lens group 110 and the vertical meridians of the corrective lens group 112 can both be parallel to the Z-axis direction. The direction of light propagation between the object plane and the reflecting mirror 10 is parallel to the Z-axis direction, and the direction of light propagation between the reflecting mirror 10 and the image plane is parallel to the X-axis direction. In other words, the first optical axis is along the Z-axis direction, and the second optical axis is parallel to the X-axis direction.

[0056] In another alternative embodiment, such as Figure 4 As shown, the anamorphic lens group 110 is located between the reflecting mirror 10 and the object plane, and the corrective lens group 112 is located between the reflecting mirror 10 and the image plane. In other words, the anamorphic lens group 110, the reflecting mirror 10, the corrective lens group 112, and the image plane are arranged sequentially along the direction of light propagation. In this embodiment, the horizontal meridian of the anamorphic lens group 110 is perpendicular to the horizontal meridian of the corrective lens group 112, and the vertical meridian of the anamorphic lens group 110 is perpendicular to the vertical meridian of the corrective lens group 112. Specifically, the horizontal meridian of the corrective lens group 112 can be parallel to the Y-axis direction, and the vertical meridian of the corrective lens group 112 can be parallel to the Z-axis direction; the horizontal meridian of the anamorphic lens group 110 can be parallel to the X-axis direction, and the vertical meridian of the anamorphic lens group 110 can be parallel to the Y-axis direction. The direction of light propagation between the object plane and the reflecting mirror 10 is parallel to the Z-axis direction, and the direction of light propagation between the reflecting mirror 10 and the image plane is parallel to the X-axis direction. In other words, the first optical axis is parallel to the Z-axis, and the second optical axis is parallel to the X-axis.

[0057] Specifically, the optical power of the morphing lens group 110 along the horizontal meridian is positive and the optical power of the correcting lens group 112 along the horizontal meridian is negative, and the radius of curvature of the morphing lens group 110 along the horizontal meridian is different from that of the correcting lens group 112 along the horizontal meridian; and / or, the optical power of the morphing lens group 110 along the vertical meridian is positive and the optical power of the correcting lens group 112 along the vertical meridian is negative, and the radius of curvature of the morphing lens group 110 along the vertical meridian is different from that of the correcting lens group 112 along the vertical meridian.

[0058] It should be noted that the optical power of the anamorphic lens group 110 along the horizontal meridian refers to the optical power of the anamorphic lens group 110 along its horizontal meridian. For example, in the embodiment where the anamorphic lens group 110 is located between the reflecting mirror 10 and the image plane, the optical power of the anamorphic lens group 110 along the horizontal meridian refers to the optical power of the anamorphic lens group 110 along the Y-axis; the optical power of the anamorphic lens group 110 along the vertical meridian refers to the optical power of the anamorphic lens group 110 along the Z-axis. In the embodiment where the anamorphic lens group 110 is located between the reflecting mirror 10 and the object plane, the optical power of the anamorphic lens group 110 along the horizontal meridian refers to the optical power of the anamorphic lens group 110 along the X-axis; the optical power of the anamorphic lens group 110 along the vertical meridian refers to the optical power of the anamorphic lens group 110 along the Y-axis. The optical power of the corrective lens group 112 along the horizontal meridian refers to the optical power of the corrective lens group 112 along the Y-axis; the optical power of the corrective lens group 112 along the vertical meridian refers to the optical power of the corrective lens group 112 along the Z-axis.

[0059] When the image sensor 2 is used to generate an image compressed in the first extension direction A (i.e., the Y-axis direction in this embodiment), the optical power of the anamorphic lens group 110 in the horizontal meridian is positive, the optical power of the corrective lens group 112 in the horizontal meridian is negative, and the radius of curvature of the anamorphic lens group 110 in the horizontal meridian is greater than the radius of curvature of the corrective lens group 112 in the horizontal meridian. When the image sensor 2 is used to generate an image magnified in the first extension direction A, the optical power of the anamorphic lens group 110 in the horizontal meridian is negative, the optical power of the corrective lens group 112 in the horizontal meridian is positive, and the radius of curvature of the anamorphic lens group 110 in the horizontal meridian is greater than the radius of curvature of the corrective lens group 112 in the horizontal meridian. When image sensor 2 is used to generate an image compressed in the second extension direction B (i.e., the Z-axis direction in this embodiment), the optical power of the anamorphic lens group 110 in the vertical meridian is positive, the optical power of the corrective lens group 112 in the vertical meridian is negative, and the radius of curvature of the anamorphic lens group 110 in the vertical meridian is greater than the radius of curvature of the corrective lens group 112 in the vertical meridian. When image sensor 2 is used to generate an image magnified in the second extension direction B, the optical power of the anamorphic lens group 110 in the vertical meridian is negative, the optical power of the corrective lens group 112 in the vertical meridian is positive, and the radius of curvature of the anamorphic lens group 110 in the vertical meridian is greater than the radius of curvature of the corrective lens group 112 in the vertical meridian.

[0060] The optical lens 1 provided in this application includes a reflector 10 and a functional lens assembly 11. The functional lens assembly 11 includes an anamorphic lens group 110 and a corrective lens group 112. When one of the optical power of the anamorphic lens group 110 and the optical power of the corrective lens group 112 in the horizontal meridian is positive and the other is negative, and the radius of curvature of the anamorphic lens group 110 in the horizontal meridian is different from that of the corrective lens group 112 in the horizontal meridian, the optical lens 1 can achieve the convergence or divergence of light in the horizontal meridian direction, which is beneficial to compressing or enlarging the size of the image sensor 2 of the camera module 100 in this direction, so as to balance the imaging effect and size of the camera module 100. When one of the optical power of the morphing lens group 110 along the vertical meridian and the optical power of the correcting lens group 112 along the vertical meridian is positive and the other is negative, and the radius of curvature of the morphing lens group 110 along the vertical meridian is different from that of the correcting lens group 112 along the vertical meridian, the optical lens 1 can achieve the convergence or divergence of light in the vertical meridian direction. This is beneficial for compressing or enlarging the size of the image sensor 2 of the camera module 100 in this direction, so as to balance the imaging effect and size of the camera module 100. This allows for the matching of a suitable image sensor 2 while ensuring that the imaging effect of the electronic device 1000 meets the design requirements, thus facilitating the development of the electronic device 1000 towards thinner, smaller, and more multifunctional devices.

[0061] In one optional embodiment, the morphing lens group 110 has a positive optical power along the vertical meridian to converge the incident light rays along the vertical meridian, while the correcting lens group 112 has a negative optical power along the vertical meridian to correct aberrations in the incident light rays along the vertical meridian. The radius of curvature of the morphing lens group 110 along the vertical meridian is greater than that of the correcting lens group 112 along the vertical meridian. Alternatively, please refer to... Figure 3 and Figure 5 When the deformable lens group 110 and the corrective lens group 112 are arranged sequentially between the reflector 10 and the image plane, the surface of the deformable lens group 110 facing the reflector 10 in its cross-section along the Z-axis can bulge towards the reflector 10; or, the surface facing the image plane can bulge towards the reflector 10. Similarly, the surface of the corrective lens group 112 facing the reflector 10 in its cross-section along the Z-axis can be concave relative to the reflector 10; or, the surface facing the image plane can bulge towards the image plane. Please refer to... Figure 4 and Figure 6When the deformable lens group 110 is located between the reflector 10 and the object plane, and the corrective lens group 112 is located between the reflector 10 and the image plane, the surface of the deformable lens group 110 facing the object plane in the cross-section along the Y-axis can bulge towards the object plane; or, the surface facing the reflector 10 can bulge towards the object plane. The surface of the corrective lens group 112 facing the reflector 10 in the cross-section along the Z-axis can be recessed relative to the reflector 10; or, the surface facing the image plane can bulge towards the image plane. Figure 4 , Figure 6 This diagram is only used to illustrate the optical structure of the deformable lens group 110 along the vertical meridian and the optical structure of the corrective lens group 112 along the vertical meridian, and should not be interpreted as a schematic diagram of the actual structural cross-section.

[0062] In one embodiment, the morphing lens group 110 has zero optical power at the horizontal meridian. Alternatively, as... Figure 7 As shown, when the deformable lens group 110 and the corrective lens group 112 are arranged sequentially between the reflector 10 and the image plane, the surfaces of the deformable lens group 110 along the Y-axis direction facing both the reflector 10 and the image plane are planar. Figure 8 As shown, when the deformable lens group 110 is located between the reflector 10 and the object plane, and the corrective lens group 112 is located between the reflector 10 and the image plane, the surfaces of the deformable lens group 110 facing the object plane and the reflector 10 in the cross-section along the X-axis are both planar. By making the optical power of the deformable lens group 110 zero along the horizontal meridian, light convergence in the Z-axis direction is achieved, thereby reducing the size of the image sensor 2 in the Z-axis direction and reducing the manufacturing difficulty of the deformable lens group 110. The optical power of the corrective lens group 112 along the horizontal meridian can be positive, negative, or zero. When the optical power of the corrective lens group 112 along the horizontal meridian is positive, the surface of the corrective lens group 112 facing the reflector 10 in the cross-section along the Y-axis can bulge towards the reflector 10; or, the surface facing the image plane can bulge towards the reflector 10. When the optical power of the correcting lens group 112 is negative along the horizontal meridian, the surface of the correcting lens group 112 on the side facing the reflecting mirror 10 in the cross-section along the Y-axis can be concave relative to the reflecting mirror 10; or, the surface on the side facing the image plane can be convex towards the image plane. Wherein, Figure 8 This diagram is only used to illustrate the optical structure of the deformable lens group 110 along the horizontal meridian and the optical structure of the corrective lens group 112 along the horizontal meridian, and should not be interpreted as a schematic diagram of the actual structural cross-section.

[0063] In another embodiment, the optical power of the anamorphic lens group 110 along the horizontal meridian is positive, and the optical power of the corrective lens group 112 along the horizontal meridian is negative. Furthermore, the radius of curvature of the anamorphic lens group 110 along the horizontal meridian is the same as that of the corrective lens group 112 along the horizontal meridian. It should be noted that allowing for some error in the approximation of the same radius of curvature between the anamorphic lens group 110 and the corrective lens group 112 allows for approximately the same radius of curvature. In this embodiment, light rays along the horizontal meridian are essentially uncompressed or amplified after passing through the anamorphic lens group 110 and the corrective lens group 112; only light rays along the perpendicular meridian are compressed or amplified after passing through these two groups. By making the optical power of the anamorphic lens group 110 positive in the vertical sub-wire and positive in the horizontal meridian, light convergence in the Z-axis direction is achieved, while reducing the surface processing difficulty of the anamorphic lens group 110 and decreasing the number of anamorphic lens groups 110. Similarly, by making the optical power of the corrective lens group 112 negative in the vertical sub-wire and negative in the horizontal meridian, aberration correction in the Z-axis direction is achieved, while reducing the surface processing difficulty of the corrective lens group 112 and decreasing the number of corrective lens groups 112. Furthermore, the functional lens assembly 11 formed by a positive optical power anamorphic lens group 110 and a negative optical power corrective lens group 112 is more conducive to achieving aberration and chromatic aberration adjustment in the horizontal meridian. In this embodiment, please refer to... Figure 9 and Figure 10 When the deformable lens group 110 and the corrective lens group 112 are arranged sequentially between the reflecting mirror 10 and the image plane, the surface of the deformable lens group 110 facing the reflecting mirror 10 in its cross-section along the Y-axis can bulge towards the reflecting mirror 10; or, the surface facing the image plane can bulge towards the reflecting mirror 10. The surface of the corrective lens group 112 facing the reflecting mirror 10 in its cross-section along the Y-axis can be concave relative to the reflecting mirror 10; or, the surface facing the image plane can bulge towards the image plane. Of course, in other embodiments, the optical power of the deformable lens group 110 along the horizontal meridian can be negative, and the optical power of the corrective lens group 112 along the horizontal meridian can be positive. Please refer to... Figure 11 and Figure 12When the deformable lens group 110 is located between the reflecting mirror 10 and the object plane, and the correcting lens group 112 is located between the reflecting mirror 10 and the image plane, the surface of the deformable lens group 110 facing the object plane in the cross-section along the X-axis can bulge towards the object plane; or, the surface facing the reflecting mirror 10 can bulge towards the object plane. The surface of the correcting lens group 112 facing the reflecting mirror 10 in the cross-section along the Y-axis can be concave relative to the reflecting mirror 10; or, the surface facing the image plane can bulge towards the image plane. Figure 11 , Figure 12 This diagram is only used to illustrate the optical structure of the deformable lens group 110 along the horizontal meridian and the optical structure of the corrective lens group 112 along the horizontal meridian, and should not be interpreted as a schematic diagram of the actual structural cross-section.

[0064] In another optional embodiment, the morphing lens group 110 has a positive optical power along the horizontal meridian to converge the incident light rays along the horizontal meridian, while the correcting lens group 112 has a negative optical power along the horizontal meridian to correct aberrations in the incident light rays along the horizontal meridian. The radius of curvature of the morphing lens group 110 along the horizontal meridian is greater than that of the correcting lens group 112 along the horizontal meridian. Alternatively, please refer to... Figure 13 and Figure 14 When the deformable lens group 110 and the corrective lens group 112 are arranged sequentially between the reflector 10 and the image plane, the surface of the deformable lens group 110 facing the reflector 10 in the cross-section along the Y-axis can bulge towards the reflector 10; or, the surface of the deformable lens group 110 facing the image plane can bulge towards the reflector 10. The surface of the corrective lens group 112 facing the reflector 10 in the cross-section along the Y-axis can be concave relative to the reflector 10; or, the surface of the corrective lens group 112 facing the image plane can bulge towards the image plane. Please refer to... Figure 15 and Figure 16 When the deformable lens group 110 is located between the reflecting mirror 10 and the object plane, and the correcting lens group 112 is located between the reflecting mirror 10 and the image plane, the surface of the deformable lens group 110 facing the object plane in the cross-section along the X-axis can bulge towards the object plane; or, the surface facing the reflecting mirror 10 can bulge towards the object plane. The surface of the correcting lens group 112 facing the reflecting mirror 10 in the cross-section along the Z-axis can be concave relative to the reflecting mirror 10; or, the surface facing the image plane can bulge towards the image plane. Figure 15 , Figure 16 This diagram is only used to illustrate the optical structure of the deformable lens group 110 along the horizontal meridian and the optical structure of the corrective lens group 112 along the horizontal meridian, and should not be interpreted as a schematic diagram of the actual structural cross-section.

[0065] In one embodiment, the morphing lens group 110 has zero optical power along the vertical meridian. Alternatively, as... Figure 17As shown, when the deformable lens group 110 and the corrective lens group 112 are arranged sequentially between the reflector 10 and the image plane, the surfaces of the deformable lens group 110 along the Z-axis direction facing the reflector 10 and the image plane are both planar. Figure 18 As shown, when the deformable lens group 110 is located between the reflector 10 and the object plane, and the corrective lens group 112 is located between the reflector 10 and the image plane, the surfaces of the deformable lens group 110 facing the object plane and the reflector 10 in the cross-section along the Y-axis are both planar. By making the optical power of the deformable lens group 110 zero along the vertical meridian, light convergence in the Y-axis direction is achieved, thereby reducing the size of the image sensor 2 in the Y-axis direction and reducing the manufacturing difficulty of the deformable lens group 110. The optical power of the corrective lens group 112 along the vertical meridian can be positive, negative, or zero. When the optical power of the corrective lens group 112 along the vertical meridian is positive, the surface of the corrective lens group 112 facing the reflector 10 in the cross-section along the Z-axis can bulge towards the reflector 10; or, the surface facing the image plane can bulge towards the reflector 10. When the optical power of the correcting lens group 112 along the vertical meridian is negative, the surface of the correcting lens group 112 facing the reflecting mirror 10 in the cross-section along the Z-axis can be concave relative to the reflecting mirror 10; or, the surface facing the image plane can be convex towards the image plane. Wherein, Figure 18 This diagram is only used to illustrate the optical structure of the deformable lens group 110 along the vertical meridian and the optical structure of the corrective lens group 112 along the vertical meridian, and should not be interpreted as a schematic diagram of the actual structural cross-section.

[0066] In another embodiment, the optical power of the anamorphic lens group 110 along the vertical meridian is positive, and the optical power of the corrective lens group 112 along the vertical meridian is negative. Furthermore, the radius of curvature of the anamorphic lens group 110 along the vertical meridian is the same as that of the corrective lens group 112 along the vertical meridian. It should be noted that allowing for some error in the approximation of the radius of curvature of the anamorphic lens group 110 and the corrective lens group 112 along the vertical meridian is permissible; that is, the radius of curvature of the anamorphic lens group 110 and the corrective lens group 112 along the vertical meridian can be approximately the same. In this embodiment, light rays along the vertical meridian experience virtually no compression or amplification after passing through the anamorphic lens group 110 and the corrective lens group 112; only light rays along the horizontal meridian experience compression or amplification after passing through these two groups. By making the optical power of the anamorphic lens group 110 positive in the horizontal sub-radius and positive in the vertical meridion, light convergence in the Y-axis direction is achieved, while reducing the surface processing difficulty of the anamorphic lens group 110 and decreasing the number of anamorphic lens groups 110. Similarly, by making the optical power of the corrective lens group 112 negative in the horizontal sub-radius and negative in the vertical meridion, aberration correction in the Z-axis direction is achieved, while reducing the surface processing difficulty of the corrective lens group 112 and decreasing the number of corrective lens groups 112. Furthermore, the functional lens assembly 11 formed by a positive optical power anamorphic lens group 110 and a negative optical power corrective lens group 112 is more conducive to achieving aberration and chromatic aberration adjustment in the vertical meridion. In this embodiment, please refer to... Figure 19 and Figure 20 When the deformable lens group 110 and the corrective lens group 112 are arranged sequentially between the reflector 10 and the image plane, the surface of the deformable lens group 110 facing the reflector 10 in the cross-section along the Z-axis can bulge towards the reflector 10; or, the surface facing the image plane can bulge towards the reflector 10. Similarly, the surface of the corrective lens group 112 facing the reflector 10 in the cross-section along the Z-axis can be concave relative to the reflector 10; or, the surface facing the image plane can bulge towards the image plane. Please refer to... Figure 21 and Figure 22When the deformable lens group 110 is located between the reflecting mirror 10 and the object plane, and the corrective lens group 112 is located between the reflecting mirror 10 and the image plane, the surface of the deformable lens group 110 facing the object plane in the cross-section along the Y-axis can bulge towards the object plane; or, the surface facing the reflecting mirror 10 can bulge towards the object plane. The surface of the corrective lens group 112 facing the reflecting mirror 10 in the cross-section along the Z-axis can be concave relative to the reflecting mirror 10; or, the surface facing the image plane can bulge towards the image plane. Of course, in other embodiments, the optical power of the deformable lens group 110 along the vertical meridian can be negative, and the optical power of the corrective lens group 112 along the vertical meridian can be positive. Figure 21 , Figure 22 This diagram is only used to illustrate the optical structure of the deformable lens group 110 along the vertical meridian and the optical structure of the corrective lens group 112 along the vertical meridian, and should not be interpreted as a schematic diagram of the actual structural cross-section.

[0067] Among them, such as Figure 23 As shown, the deformable lens group 110 includes any one or a combination of any two or three of cylindrical lenses, toric lenses, and freeform lenses.

In an optional embodiment, such as... Figure 23As shown, the correction lens group 112 is located between the reflecting mirror 10 and at least one imaging lens 120. In other words, the reflecting mirror 10, the correction lens group 112, at least one imaging lens 120, and the image sensor 2 are arranged sequentially along the second optical axis. The deformable lens group 110 can be located between the reflecting mirror 10 and the correction lens group 112, or it can be located between the reflecting mirror 10 and the object surface. In another optional embodiment, such as Figure 24 As shown, the correction lens group 112 is located between at least one imaging lens 120 and the image plane. In other words, the reflector 10, at least one imaging lens 120, the correction lens group 112, and the image sensor 2 are arranged sequentially along the second optical axis.

[0069] This application does not specify the number of imaging lenses 120; the accompanying drawings illustrate four imaging lenses 120. At least one imaging lens 120 includes at least one aspherical lens. Aspherical lenses are superior to spherical lenses in improving chromatic aberration and reducing aberrations, and are also thinner and lighter.

[0070] In another alternative embodiment, such as Figure 26 As shown, the optical lens 1 also includes an imaging lens group 12. The imaging lens group 12 includes at least one first imaging lens 121 and at least one second imaging lens 122. The at least one first imaging lens 121 is used to overcome the imaging defects of the functional lens assembly 11, improving chromatic aberration, aberrations, etc. The at least one second imaging lens 122 is used to overcome the imaging defects of the functional lens assembly 11, improving chromatic aberration, aberrations, etc. The at least one first imaging lens 121 is located between the reflecting mirror 10 and the image plane, the at least one second imaging lens 122 is located between the reflecting mirror 10 and the image plane, and the correction lens group 112 is located between the at least one first imaging lens 121 and the at least one second imaging lens 122.

[0073] In one alternative embodiment, such as Figure 29 As shown, the deformable lens group 110 is located between the reflector 10 and the object surface, and is integrated with the protective lens 13. Specifically, the deformable lens group 110 and the protective lens 13 are integrated to form a multifunctional lens 15. The surface of the multifunctional lens 15 facing away from the reflector 10 can be flat, while the surface of the multifunctional lens 15 facing the reflector 10 is curved, in order to achieve functions such as protection, light convergence, or light divergence. In this embodiment, integrating the deformable lens group 110 and the protective lens 13 into one unit can improve the structural compactness of the camera module 100 and reduce the size of the camera module 100.
