Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present application and are not to be construed as limiting the present application.

Referring to fig. 1, an electronic device 1000 according to an embodiment of the application includes a housing 110, a camera assembly 100, and a battery 120. The camera assembly 100 is disposed at the housing 110 and exposed through the housing 110. The battery 120 is disposed within the housing 110.

By way of example, the electronic apparatus 1000 may be any of various types of computer system devices that are mobile or portable and that perform wireless communications (only one form of which is shown by way of example in FIG. 1).

In particular, the electronic apparatus 1000 may be a mobile phone or a smart phone (e.g., phone based on iPhone system, android system), portable game device (e.g., iPhone (apple phone)), a laptop, a palmtop (personal DIGITAL ASSISTANT, PDA), a portable internet device, a music player, and a data storage device, other handheld devices, and devices such as a wristwatch, an in-ear headset, a pendant, a headset, and the like.

The electronic apparatus 100 may also be other wearable devices (e.g., a head-mounted device (head mount display, HMD) such as electronic glasses, electronic clothing, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices, or smart watches).

The housing 110 is an external component of the electronic device 1000, and serves to protect internal components of the electronic device 1000. The housing 110 may be a rear cover of the electronic device 1000, and the rear cover covers components such as the battery 120 of the electronic device 1000.

In this embodiment, the camera module 100 is disposed at the back of the electronic device 1000, so that the electronic device 1000 can perform the rear-mounted image capturing. As in the example of fig. 1, camera assembly 100 is disposed at an intermediate-high position of housing 110. The battery 120 is disposed at a lower position of the electronic device 1000. Alternatively, the camera module 100 and the battery 120 are disposed at intervals along the longitudinal direction of the electronic device 1000. In this way, the camera module 100 and the battery 120 can be prevented from being stacked in the thickness direction of the electronic device 1000, so that the thickness of the electronic device 1000 can be reduced, and interference between the camera module 100 and the battery 120 can be prevented.

Of course, it is understood that the camera assembly 100 may be disposed in other locations such as an upper left or upper right position of the housing 110. The location where the camera assembly 100 is disposed in the housing 110 is not limited to the examples of the present application.

Referring to fig. 2 and 3, the camera assembly 100 includes a periscope type camera 20, a first wide angle camera 30, a second wide angle camera 40, a bracket 50 and a flash 60.

Periscope type camera 20, first wide-angle camera 30 and second wide-angle camera 40 are all arranged in support 50 and fixedly connected with support 50. The stand 50 can reduce the impact received by the periscope type camera 20, the first wide-angle camera 30 and the second wide-angle camera 40, and improve the life of the periscope type camera 20, the first wide-angle camera 30 and the second wide-angle camera 40.

In the present embodiment, the field angle FOV3 of the second wide-angle camera 40 is larger than the field angle FOV1 of the periscope camera 20 and smaller than the field angle FOV2 of the first wide-angle camera 30, that is, FOV1 < FOV3 < FOV2. Thus, the three cameras with different angles of view enable the camera assembly 100 to meet shooting requirements in different scenes.

The wide-angle camera according to the present embodiment means that the angle of view of the camera is greater than 60 degrees.

In one example, periscope type camera 20 has a field angle FOV1 of 10-30 degrees, first wide angle camera 30 has a field angle FOV2 of 110-130 degrees, and second wide angle camera 40 has a field angle FOV3 of 80-110 degrees.

For example, the periscope type camera 20 has a field angle FOV1 of 10 degrees, 12 degrees, 15 degrees, 20 degrees, 26 degrees, 30 degrees, or the like. The first wide-angle camera 30 has a field angle FOV2 of 110 degrees, 112 degrees, 118 degrees, 120 degrees, 125 degrees, or 130 degrees. The second wide-angle camera 40 has a field angle FOV3 of 80 degrees, 85 degrees, 90 degrees, 100 degrees, 105 degrees, or 110 degrees.

Since the field angle FOV1 of the periscope type camera 20 is small, it can be understood that the focal length of the periscope type camera 20 is large, and therefore the periscope type camera 20 can be used for shooting a long-range view, thereby obtaining a clear image of the long-range view. The field angle FOV2 of the first wide-angle camera 30 is large, and it is understood that the focal length of the first wide-angle camera 30 is short, and thus the first wide-angle camera 30 can be used to capture close-up images, thereby obtaining a partial close-up image of an object. The second wide-angle camera 40 may be used to normally photograph an object.

In this way, by combining the periscope type camera 20, the first wide-angle camera 30, and the second wide-angle camera 40, image effects such as background blurring, local sharpening of pictures, and the like can be obtained.

The first wide angle camera 30 is disposed near the periscope type camera 20. The second wide-angle camera 40 is disposed close to the first wide-angle camera 30. The first wide-angle camera 30 is disposed between the periscope type camera 20 and the second wide-angle camera 40.

Periscope type camera 20, first wide-angle camera 30 and second wide-angle camera 40 are arranged linearly. The flash 60 is disposed on a side of the periscope-type camera 20 facing away from the first wide-angle camera 30. In this embodiment, periscope type camera 20, first wide-angle camera 30, and second wide-angle camera 40 are arranged in an L shape.

Alternatively, referring to fig. 3, the periscope type camera 20 is configured to turn and image light entering from the light entrance axis 101 of the periscope type camera 20 to an imaging optical axis 102 of the periscope type camera 20 substantially perpendicular to the light entrance axis 101 of the periscope type camera 20, where the light entrance axis 101 of the periscope type camera 20 is substantially parallel to the optical axes 301 and 302 of the first and second wide-angle cameras 30 and 40, and the imaging optical axis 102 is substantially perpendicular to the arrangement directions of the periscope type camera 20, the first and second wide-angle cameras 30 and 40.

In this way, the optical axis 101 of the periscope type camera 20 is substantially parallel to the optical axis 301 of the first wide-angle camera 30 and the optical axis 302 of the second wide-angle camera 40, the imaging optical axis 102 of the periscope type camera 20 is substantially perpendicular to the arrangement directions of the periscope type camera 20, the first wide-angle camera 30 and the second wide-angle camera 40, so that the camera assembly 100 can be prevented from being larger in a single direction, and other parts of the electronic device 1000 are prevented from being interfered when the camera assembly 100 is applied to the electronic device 1000 such as a mobile phone, and the layout of other parts of the electronic device 1000 is facilitated.

It should be noted that, the light entering from the light entrance axis 101 of the periscope type camera 20 refers to the light entering the periscope type camera 20 with the light entrance axis 101 as the center, and the light may be parallel to the light entrance axis 101 or may form a certain angle with the light entrance axis 101.

In addition, the light beam that is turned to the imaging optical axis 102 refers to a light beam that propagates around the imaging optical axis 102, and the light beam may be parallel to the imaging optical axis 102 or may form a certain angle with the imaging optical axis 102.

It will be appreciated that if the periscope type camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 are arranged in a straight line, the size of the camera assembly 100 in the direction in which the periscope type camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 are arranged is larger, which is disadvantageous for the installation of the camera assembly 100 into an electronic device.

In addition, referring to fig. 1, in the present embodiment, the light inlet 211 of the periscope type camera 20, the light inlet 311 of the first wide-angle camera 30 and the light inlet 411 of the second wide-angle camera 40 are arranged along the longitudinal direction of the electronic device 1000, and the length direction of the periscope type camera 20 is arranged along the transverse direction of the electronic device 1000.

Alternatively, when the camera assembly 100 is applied to the electronic device 1000, the light inlet 211 of the periscope type camera 20, the light inlet 311 of the first wide-angle camera 30 and the light inlet 411 of the second wide-angle camera 40 are arranged along the longitudinal direction of the electronic device 1000, and the length direction of the periscope type camera 20 is arranged along the transverse direction of the electronic device 1000.

Further, the light entrance axis 101 of the periscope type camera 20 is coplanar with the light axes of the first wide-angle camera 30 and the second wide-angle camera 40, which is beneficial to simplifying the image algorithm, so that the image with better quality can be obtained more easily.

Because of the view angle factors of the periscope type camera 20 and the second wide-angle camera 40, in order to enable the periscope type camera 20 and the second wide-angle camera 40 to obtain images with better quality, the periscope type camera 20 and the second wide-angle camera 40 can be provided with an optical anti-shake device, and the optical anti-shake device is generally provided with more magnetic elements, so that the periscope type camera 20 and the second wide-angle camera 40 can generate magnetic fields.

In this embodiment, the first wide-angle camera 30 is located between the periscope type camera 20 and the second wide-angle camera 40, so that the periscope type camera 20 and the second wide-angle camera 40 can be far away, and the magnetic field formed by the periscope type camera 20 and the magnetic field formed by the second wide-angle camera 40 are prevented from interfering with each other to affect the normal use of the periscope type camera 20 and the second wide-angle camera 40.

Periscope type camera 20, first wide-angle camera 30 and second wide-angle camera 40 can be arranged at intervals, and two adjacent cameras can also be abutted against each other.

Any one of the periscope type camera 20, the first wide-angle camera 30 and the second wide-angle camera 30 may be a black-and-white camera, an RGB camera or an infrared camera.

It should be noted that the terms "first," "second," and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Referring to fig. 4-6, the periscope camera 20 of the present embodiment includes a periscope lens 10, a housing 21, a first lens assembly 24, a loading element 25, a first image sensor 26, a driving mechanism 27, and a driving device 28.

The first lens assembly 24, the loading element 25 are both disposed within the housing 21. The first lens assembly 24 is secured to the loading element 25. The loading element 25 is provided on the first image sensor 26 side. Further, the loading element 25 is located between the periscope lens 10 and the first image sensor 26.

The drive mechanism 27 connects the loading element 25 with the housing 21. After entering the periscope camera 20, the incident light is diverted through the periscope lens 10 and then passes through the first lens assembly 24 to reach the first image sensor 26, so that the first image sensor 26 obtains an external image. The drive mechanism 27 is used to drive the loading element 25 along the optical axis of the first lens assembly 24 to focus the first lens assembly 24 on the first image sensor 26.

Referring to fig. 7 and 8, in the present embodiment, the periscope lens 10 includes a barrel 11, a light conversion element 12 and a two-axis hinge 13. The light conversion element 12 is disposed in the lens barrel 11. The light conversion element 12 is used to convert light from the light entrance axis 101 to the imaging optical axis 102, and the imaging optical axis 102 is perpendicular to the light entrance axis 101. Alternatively, the light-converting element 12 is configured to convert light from the light-entering axis 101 to the first image sensor 26.

The biaxial hinge 13 rotatably connects the lens barrel 11 and the light conversion element 12. The biaxial hinge 13 includes a first rotation shaft 103 and a second rotation shaft 104, the first rotation shaft 103 being perpendicular to the optical axis of advance 101 and the imaging optical axis 102, the second rotation shaft 104 being parallel to the optical axis of advance 101.

In this way, the first rotating shaft 103 and the second rotating shaft 104 of the biaxial hinge 13 can enable the light conversion element 12 to rotate in two directions, and the rotation precision of the light conversion element 12 is high, so that the camera with the periscope type lens 10 can achieve a better optical anti-shake effect in two directions. In addition, the biaxial hinge 13 is compact, and the volume of the periscope lens 10 can be reduced.

It will be appreciated that periscope camera 20 is a periscope lens module. Compared with a vertical lens module, the periscope type lens module has smaller height, so that the overall thickness of the electronic device 1000 can be reduced. The vertical lens module refers to that an imaging optical axis and an optical inlet axis of the lens module are in a straight line. Or, the incident light is conducted to the photosensitive device of the lens module along the direction of a linear optical axis.

Specifically, the lens barrel 11 has a substantially square shape. The lens barrel 11 may be made of plastic, metal, or the like. The lens barrel 11 has a light inlet 211, and incident light enters the periscope 10 from the light inlet 211. That is, the light conversion element 12 is configured to convert the incident light entering from the light inlet 211 and transmit the converted incident light to the first image sensor 26 through the first lens assembly 24, so that the first image sensor 26 senses the incident light outside the periscope type camera 20.

Referring to fig. 5 and 7, the lens barrel 11 includes a top wall 213, side walls 214, and a bottom wall 216. Side walls 214 are formed extending from side edges 2131 of top wall 213. The bottom wall 216 is opposite the top wall 213. The top wall 213 is formed with a light inlet 211, or the light inlet 211 is formed in the top wall 213. The top wall 213 includes two opposite sides 2131. The number of side walls 214 is two, each side wall 214 extending from a corresponding one of the side edges 2131. Alternatively, the side walls 214 are respectively connected to opposite sides of the top wall 213.

The light conversion element 12 includes a light conversion portion 22 and a mounting portion 23, and the light conversion portion 22 is provided on the mounting portion 23. The light conversion part 22 can be fixed on the mounting part 23 by adopting adhesive bonding so as to realize fixed connection with the mounting part 23.

The light conversion portion 22 is a prism or a plane mirror. In one example, when the light conversion portion 22 is a prism, the prism may be a triangular prism, and the cross section of the prism is a right triangle, where light enters from one right angle surface in the right triangle, and then exits from the other right angle surface after being reflected.

Of course, the incident light may exit after being refracted by the prism, without being reflected. The prism can be made of materials with good light transmittance such as glass, plastic and the like. In one embodiment, a reflective material such as silver may be coated on one of the surfaces of the prism to reflect incident light.

It will be appreciated that when the light converting portion 22 is a flat mirror, the flat mirror reflects the incident light to thereby effect the turning of the incident light.

Further, referring to fig. 7 and 9, the light conversion portion 22 has a light incident surface 222, a backlight surface 224, a light conversion surface 226 and a light emergent surface 228. The light incident surface 222 is close to and faces the light inlet 211. The backlight surface 224 is far away from the light inlet 211 and is opposite to the light inlet surface 222. The light-turning surface 226 is connected to the light-incident surface 222 and the backlight surface 224. The light-emitting surface 228 is connected to the light-entering surface 222 and the backlight surface 224. The light-emitting surface 228 faces the first image sensor 26. The light-turning surface 226 is disposed obliquely with respect to the light-incident surface 222. The light emitting surface 228 is disposed opposite to the light converting surface 226.

Specifically, during the light turning process, the light passes through the light inlet 211 and enters the light turning portion 22 from the light inlet 222, then turns through the light turning surface 226, and finally reflects out of the light turning portion 22 from the light outlet 228, thereby completing the light turning process. The backlight surface 224 is fixedly disposed with the mounting portion 23 so that the light conversion portion 22 is kept stable.

As shown in fig. 10, in the related art, the light-turning surface 226a of the light-turning portion 22a is inclined with respect to the horizontal direction due to the need to reflect the incident light, and the light-turning portion 22a is of an asymmetric structure in the reflection direction of the light. Thus, the actual optical area below the light conversion portion 22a is smaller than the actual optical area above the light conversion portion 22 a. It will be appreciated that the portion of the light turning surface 226a away from the light inlet may reflect less or no light.

Therefore, referring to fig. 11, the light-converting portion 22 according to the embodiment of the present application has the edges and corners away from the light-entering opening cut away from the light-converting portion 22a in the related art, so that the effect of the reflected light of the light-converting portion 22 is not affected, and the overall thickness of the light-converting portion 22 is reduced.

Referring to fig. 7 again, the light-turning surface 226 is inclined at an angle α of 45 ° with respect to the light-entering surface 222. Therefore, the incident light rays are reflected and converted better, and the light ray conversion effect is better.

Further, the light conversion portion 22 may be made of a material having relatively good light transmittance such as glass or plastic. In one embodiment, a reflective material such as silver may be coated on one of the surfaces of the light conversion part 22 to reflect incident light. Of course, the light conversion portion 22 can utilize the principle of total reflection of light to realize the incident light conversion. At this time, the light-reflecting material does not need to be coated on the light-converting portion 22.

As in the example of fig. 7, the light incident surface 222 is disposed parallel to the backlight surface 224. In this way, when the backlight surface 224 and the mounting portion 23 are fixedly arranged, the light-converting portion 22 can be kept stable, the light-entering surface 222 is also in a plane, and the incident light forms a regular light path during the conversion process of the light-converting portion 22, so that the conversion efficiency of the light is better.

Specifically, the light conversion portion 22 has a substantially trapezoidal cross section along the light incident direction of the light inlet 211, or the light conversion portion 22 has a substantially trapezoidal shape. As in the example of fig. 7, the light-in surface 222 and the backlight surface 224 are both perpendicular to the light-out surface 228. Therefore, the regular light conversion part 22 can be formed, so that the light path of the incident light is straight, and the light conversion efficiency is improved.

In one example, the distance between the light incident surface 222 and the backlight surface 224 is in the range of 4.8-5.0mm. For example, the distance between the light incident surface 222 and the backlight surface 224 may be 4.85mm, 4.9mm, 4.95mm, or the like. Alternatively, the distance between the light incident surface 222 and the backlight surface 224 can be understood as the height of the light converting portion 22 is 4.8-5.0mm.

The light-converting portion 22 formed by the light-incident surface 222 and the backlight surface 224 in the above distance range has moderate volume, and can be better fit into the periscope type camera 20, so that the periscope type camera 20, the camera assembly 100 and the electronic device 1000 which are more compact and miniaturized are formed, and more requirements of consumers are met.

Optionally, the light incident surface 222, the backlight surface 224, the light turning surface 226 and the light exiting surface 228 are all hardened to form a hardened layer.

When the light conversion portion 22 is made of glass or other material, the light conversion portion 22 itself is brittle, and in order to increase the strength of the light conversion portion 22, hardening treatment may be performed on the light incident surface 222, the backlight surface 224, the light conversion surface 226, and the light emitting surface 228 of the light conversion portion 22. Further, hardening treatment may be performed on all surfaces of the light conversion element 12 to further increase the strength of the light conversion element 12.

Further, the hardening treatment may be to infiltrate lithium ions, or to apply films to the respective surfaces described above without affecting the light conversion of the light conversion portion 22.

In one example, the light conversion unit 22 converts the incident light from the light inlet 211 to 90 degrees. For example, the incident angle of the incident light on the emission surface of the light conversion section 22 is 45 degrees, and the reflection angle is also 45 degrees. Of course, the angle at which the light conversion unit 22 converts the incident light may be other angles, for example, 80 degrees, 100 degrees, or the like, as long as the incident light can be converted and then reach the first image sensor 26.

In the present embodiment, the number of light conversion units 22 is one, and at this time, the incident light is once converted and then transmitted to the first image sensor 26. In other embodiments, the number of light conversion units 22 is plural, and at this time, the incident light is diverted at least twice and then transmitted to the first image sensor 26.

The mounting portion 23 is used for mounting the light conversion portion 22, or the mounting portion 23 is a carrier of the light conversion portion 22. The light conversion section 22 is fixed to the mounting section 23. This allows the position of the light converting portion 22 to be determined, which is advantageous for the light converting portion 22 to reflect or refract incident light.

Specifically, referring to fig. 5, in the present embodiment, the mounting portion 23 is provided with a limiting structure 232, and the limiting structure 232 is connected to the light conversion portion 22 to limit the position of the light conversion portion 22 on the mounting portion 23.

In this way, the limiting structure 232 limits the position of the light conversion portion 22 on the mounting portion 23, so that the light conversion portion 22 will not shift when being impacted, which is beneficial to the normal use of the periscope type camera 20.

It will be appreciated that, in one example, the light conversion portion 22 is fixed to the mounting portion 23 by adhesion, and if the limit structure 232 is omitted, the periscope camera 20 is impacted, and if the adhesion between the light conversion portion 2222 and the mounting portion 23 is insufficient, the light conversion portion 22 is easily detached from the mounting portion 23.

In the present embodiment, the mounting portion 23 is formed with a receiving groove 233, the light conversion portion 22 is disposed in the receiving groove 233, and the limiting structure 232 is disposed at an edge of the receiving groove 233 and abuts against the light conversion portion 22.

In this way, the accommodation groove 233 can make it easy to mount the light conversion portion 22 on the mounting portion 23. The limiting structure 232 is disposed at the edge of the accommodating groove 233 and abuts against the edge of the light conversion portion 22, so that not only the position of the light conversion portion 22 can be limited, but also the light conversion portion 22 is not prevented from emitting incident light to the first image sensor 26.

Further, the limiting structure 232 includes a protrusion 234 protruding from an edge of the accommodating groove 233, and the protrusion 234 abuts against an edge of the light-emitting surface 228.

Since the light conversion portion 22 is mounted on the mounting portion 23 through the light conversion surface 226, the light exit surface 228 is disposed opposite to the light conversion surface 226. Therefore, the light conversion portion 22 is more likely to be located toward the light exit surface 228 when an impact is applied. In the present embodiment, the limiting structure 232 abuts against the edge of the light emitting surface 228, so that not only the light conversion portion 22 is prevented from being displaced toward the light emitting surface 228, but also the light can be ensured to be emitted normally from the light emitting surface 228.

Of course, in other embodiments, the limiting structure 232 may include other structures as long as the position of the light conversion portion 22 can be limited. For example, the limiting structure 232 is formed with a slot, and the light conversion portion 22 is formed with a limiting post, and the limiting post is engaged in the slot to limit the position of the light conversion portion 22.

In this embodiment, the protrusion 234 is strip-shaped and extends along the edge of the light-emitting surface 228. In this way, the contact area between the protrusion 234 and the edge of the light emitting surface 228 is large, so that the light conversion portion 22 can be more firmly located in the mounting portion 23.

Of course, in other embodiments, the protrusion 234 may have other structures such as a block shape.

It can be appreciated that the mounting portion 23 can drive the light conversion portion 22 to rotate together in a direction opposite to the shake of the periscope type camera 20, so as to compensate the incident deviation of the incident light of the light inlet 211, and achieve the optical shake preventing effect.

Referring to fig. 6-8, in the present embodiment, the two-axis hinge 13 includes a connecting member 14, a limiting structure 15, a first rotating member 16 and a second rotating member 17. The restriction structure 15 serves to restrict the degrees of freedom of the light conversion element 12 and the connection member 14 in the imaging optical axis 102 direction. The first rotation member 16 rotates the connection barrel 11 and the connection member 14. The first rotating member 16 forms a first rotating shaft 103. The second rotating member 17 rotates the connection light conversion member 12 and the connection member 14. The second rotating member 17 forms a second rotating shaft 104.

In this way, the first rotating member 16 and the second rotating member 17 can realize rotation of the light turning element 12 in both directions. Specifically, the first rotation member 16 is formed with a first rotation shaft 103 such that the light conversion member 12 can be rotated about the first rotation shaft 103 by the connection member 14. The second rotating member 17 is formed with a second rotating shaft 104 such that the light-converting element 12 can rotate around the second rotating shaft 104.

Referring to fig. 5 to 7, for convenience of description, the width direction of the periscope type camera 20 is defined as the X direction, the height direction is defined as the Y direction, and the length direction is defined as the Z direction. Thus, the optical axis 101 extends in the Y direction, the imaging optical axis 102 extends in the Z direction, the first rotation axis 103 extends in the X direction, and the second rotation axis 104 extends in the Y direction.

That is, the light conversion element 12 may be rotated around the X direction by the first rotating member 16, so that the periscopic camera 20 realizes optical anti-shake in the Y direction. In addition, the light conversion element 12 may be rotated around the Y direction by the second rotation member 17, so that the periscopic camera 20 realizes optical anti-shake in the X direction.

Of course, in other embodiments, the first rotating member 16 may form the second rotating shaft 104 and the second rotating member 17 may form the first rotating shaft 103. That is, the periscope type camera 20 can be made to realize optical anti-shake in the X direction by the first rotating member 16, and the periscope type camera 20 can be made to realize optical anti-shake in the Y direction by the second rotating member 17.

In the present embodiment, the connector 14 may have a square shape, an irregular shape, or the like. In addition, the connecting member 14 may be made of plastic, metal, or the like. To reduce the weight of periscope lens 10, connector 14 may be made of a relatively low density material. Accordingly, in the present embodiment, the shape and material of the connection member 14 are not limited.

The restriction structure 15 can restrict the degree of freedom of the connection member 14 and the light conversion element 12 in the Z direction, so that the connection member 14 and the light conversion element 12 can be prevented from being scattered.

Referring to fig. 7, in an example, the limiting structure 15 includes a first magnetic element 151 and a second magnetic element 152, the first magnetic element 151 is disposed on the lens barrel 11, the second magnetic element 152 is disposed on the light conversion element 12, and the first magnetic element 151 and the second magnetic element 152 are attracted.

In this way, the magnetic elements attract, so that the degree of freedom of the connector 14 and the light conversion element 12 in the Z direction can be limited. Specifically, the lens barrel 11 is formed with a first mounting groove 112. The first magnetic element 151 is disposed in the first mounting slot 112. The light conversion element 12 is formed with a second mounting groove 122, and a second magnetic element 152 is disposed in the second mounting groove 122. Thus, the structure among the limiting structure 15, the lens barrel 11 and the light conversion element 12 is more compact, and the volume of the periscope type lens can be reduced.

In the present embodiment, the first mounting groove 112 is formed in the side wall 214 of the lens barrel 11. The second mounting groove 122 is formed in the mounting portion 23.

Referring to fig. 8, in another example, the limiting structure 15 includes a first flexible element 153 and a second flexible element 154, the first flexible element 153 connects the lens barrel 11 and the connecting member 14, and the second flexible element 154 connects the connecting member 14 and the light conversion member 12. The first flexible member 153 and the second flexible member 154 are elastic members such as wires, plastic members, and the like.

As shown in fig. 7 and 8, in the present embodiment, the connector 14 and the lens barrel 11 together define a first accommodating space 141, and the first rotator 16 is disposed in the first accommodating space 141. In addition, the light conversion element 12 and the connecting member 14 together define a second accommodating space 142, and the second rotating member 17 is disposed in the second accommodating space 142. The first and second receiving spaces 141 and 142 may make the structure of the biaxial hinge 13 more compact, thereby reducing the volume of the periscope lens 10.

Specifically, the connector 14 and the sidewall 214 together define a first receiving space 141. The connection member 14 and the mounting portion 2323 together define a second receiving space 142. The first and second receiving spaces 141 and 142 may have a cylindrical shape or a spherical shape.

The first rotational member 16 rotationally connects the side wall 214 and the connecting member 14. The first rotary member 16 includes rollers and/or balls. That is, the first rotating member 16 may be a roller, a ball, or the first rotating member 16 may include a roller and a ball. It will be appreciated that the roller is elongate. The balls are spherical. The first rotary member 16 may be made of metal or plastic. In order to reduce the friction of the first rotary member 16, the surface of the first rotary member 16 may be provided with a film layer made of low friction coefficient such as polytetrafluoroethylene.

The number of the first rotating members 16 is plural, and the plural first rotating members 16 are disposed at intervals along the first rotating shaft 103. For example, the number of first rotating members 16 is 2, 3, or 4, etc. As described above, it is understood that part of the first rotating member 16 may be a roller, and the other part of the first rotating member 16 may be a ball.

The second rotating member 17 rotatably connects the mounting portion 23 and the connecting member 14. The second rotating member 17 comprises rollers and/or balls. That is, the second rotating member 17 may be a roller, a ball, or the second rotating member 17 may include a roller and a ball. It will be appreciated that the roller is elongate. The balls are spherical. The second rotating member 17 may be made of metal or plastic. In order to reduce the friction of the second rotating member 17, the surface of the second rotating member 17 may be provided with a film layer made of low friction coefficient such as polytetrafluoroethylene.

The number of the second rotating members 17 is plural, and the plural second rotating members 17 are disposed at intervals along the second rotating shaft 104. For example, the number of the second rotating members 17 is 2, 3, or 4 or the like. As described above, it is understood that part of the second rotating member 17 may be a roller, and the other part of the second rotating member 17 may be a ball.

Referring to fig. 7 and 9 again, further, the periscope lens further includes a driving device 28, and the driving device 28 is used for driving the mounting portion 23 with the light conversion portion 22 to rotate around the first rotation axis 103 and the second rotation axis 104.

In this way, the driving device 28 drives the mounting portion 23 to move in two directions, so that not only the optical anti-shake effect of the periscope type camera 20 in two directions can be achieved, but also the volume of the periscope type camera 20 can be made smaller.

The driving device 28 drives the mounting portion 23 to rotate, so that the light conversion portion 22 rotates around the X direction, and the periscope type camera 20 achieves the Y-direction optical anti-shake effect. In addition, the driving device 28 drives the mounting portion 23 to move along the axial direction of the rotation axis 29, so that the periscopic camera 20 achieves the X-direction optical anti-shake effect. Additionally, the first lens assembly 24 may be along the Z-direction to achieve focusing of the first lens assembly 24 on the first image sensor 26.

Specifically, when the light conversion part 22 rotates around the X direction, the light reflected by the light conversion part 22 moves in the Y direction, so that the first image sensor 26 forms different images in the Y direction to achieve the anti-shake effect in the Y direction. When the light conversion unit 22 moves along the X direction, the light turned by the light conversion unit 22 moves in the X direction, so that the first image sensor 26 forms different images in the X direction to achieve the anti-shake effect in the X direction.

Referring to fig. 7-8 and 12 again, the driving device 28 includes a sensing element 281, a first electromagnetic element 282, a third magnetic element 283, a driving circuit board 285, a second electromagnetic element 286 and a fourth magnetic element 287.

The sensing element 281 is arranged outside the first electromagnetic element 282. The sensing element 281 is used for detecting the rotation angle of the light conversion portion 22. The first electromagnetic element 282 is disposed on the light conversion portion 22 side. The first electromagnetic element 282 is configured to drive the light conversion unit 22 to rotate according to the data detected by the sensing element 281, so as to implement optical anti-shake for the periscope type camera 20.

Further, the first electromagnetic element 282 is configured to drive the mounting portion 23 to rotate according to the data detected by the sensing element 281 to drive the light conversion portion 22 to rotate.

Alternatively, the sensing element 281 is a hall sensor, the first electromagnetic element 282 is a coil, and the third magnetic element 283 is a permanent magnet.

So, the sensing element 281 is disposed outside the first electromagnetic element 282, when the position of the sensing element 281 is shifted in the assembly process, the detected sensing data deviation can be avoided to be larger, the sensing element 281 is ensured to normally participate in optical anti-shake, and meanwhile, the accuracy of the data collected by the sensing element 281 can be improved, which is beneficial to improving the accuracy of optical anti-shake.

The related art generally sets a hall sensor at the center of a coil such that an initial value of the hall sensor is 0, thereby maximizing a range of the hall sensor. However, during the assembly of the components, the positions of the components may shift, resulting in errors in the data measured by the hall sensor. For example, the hall sensor is arranged in the center of the coil, the initial value of the hall sensor is 0mv, and after assembly, the offset of the position causes the hall sensor to deviate by 10mv in practice, and the influence caused by the deviation is 100%.

If the hall sensor is arranged outside the coil, the hall sensor forms a non-zero initial value, so that the influence caused by the deviation can be reduced. For example, when the hall sensor is disposed outside the coil, the initial value of the hall sensor is 140mv, and when the hall sensor is assembled, the hall sensor is actually biased by 10mv due to the positional deviation, and the influence of the bias is 7%.

The U direction is defined as a direction in which the light conversion unit 22 moves in the X direction, and the V direction is a direction in which the light conversion unit 22 rotates around the X direction.

Referring to fig. 13 and 14, the U direction is defined as the direction in which the light conversion portion 22 moves in the X direction, and the V direction is defined as the direction in which the light conversion portion 22 rotates around the X direction.

Fig. 13 is a simulation result of the deviation rate of the U-direction and V-direction hall sensors in the related art. Fig. 14 is a simulation result of the deviation rate of the hall sensor in the U direction and the V direction in the present application. Wherein the horizontal axis is the deviation rate and the vertical axis is the number of samples falling within the corresponding deviation rate. Deviation ratio (%) = ((actual value-central value)/range of hall sensor) ×100%. The measuring range of the Hall sensor is within the range of +/-1.5 degrees.

As can be seen from fig. 13 and 14, the present application is more concentrated in the V direction, that is, the deviation rate is smaller, than the prior art. Furthermore, the application can reduce the deviation rate of the Hall sensor in the V direction to one thousandth of the deviation rate of the prior art.

Referring to fig. 12, a first electromagnetic element 282 is disposed on the bottom wall 216. The first electromagnetic element 282 is annular, the first electromagnetic element 282 has a first centerline 2821, and the sensing element 281 is disposed offset from the first centerline 2821. The distance a of the center of the sensing element 281 from the first center line 2821 of the first electromagnetic element 282 is in the range of 0.5mm-1.0mm.

In the case where the distance a between the center of the sensing element 281 and the first center line 2821 of the first electromagnetic element 282 is in the range of 0.5mm to 1.0mm, the initial value after the offset is preferable. It can be appreciated that the initial value after the offset cannot be too small, so that the offset rate cannot be reduced more; the initial value after the offset cannot be too large, so that the range of the Hall sensor is insufficient.

Preferably, the center of the sensing element 281 is spaced from the first centerline 2821 of the first electromagnetic element 282 by 0.75mm.

In another example, the distance A from the center of the sensing element 281 to the first centerline 2821 of the first electromagnetic element 282 is 0.5mm; in yet another example, the center of the inductive element 281 is a distance A of 0.8mm from the first centerline 2821 of the first electromagnetic element 282; in yet another example, the center of the inductive element 281 is 1mm from the first centerline 2821 of the first electromagnetic element 282. A specific value of the distance a of the center of the sensing element 281 from the first center line 2821 of the first electromagnetic element 282 is not limited herein.

It will be appreciated that the first electromagnetic component 282 may also be circular, square, or any other shape, and the particular shape of the first electromagnetic component 282 is not limited herein.

In addition, in the example of fig. 12, the sensing element 281 is located on one side of the first electromagnetic element 282, it being understood that in other examples, the sensing element 281 may be located on the other side of the first electromagnetic element 282. As long as the sensing element 281 does not interfere with the existing structure of the periscope type camera 20, the specific position of the sensing element 281 is not limited here.

The first electromagnetic element 282 has a second center line 2822, the second center line 2822 is perpendicular to the first center line 2821, the second center line 2822 intersects the first center line 2821 at the center of the first electromagnetic element 282, the number of the sensing elements 281 is two, and the two sensing elements 281 are symmetrically arranged with respect to the second center line 2822 of the first electromagnetic element 282.

In this way, the data measured by the first electromagnetic component 282 may be made more accurate. Specifically, the data output by the two first electromagnetic elements 282 may be calculated, e.g., averaged, to obtain more accurate data. In addition, when one of the first electromagnetic elements 282 is abnormal, the other first electromagnetic element 282 can ensure the normal operation of the optical anti-shake, which is beneficial to improving the reliability of the driving device 28.

Of course, in other examples, the number of sensing elements 281 may be 3,4, or any other number, and the specific number of sensing elements 281 is not limited herein.

The third magnetic element 283 is disposed on the light conversion element 12. Specifically, the third magnetic element 283 is disposed on the mounting portion 23, and the first electromagnetic element 282 cooperates with the third magnetic element 283 to drive the light conversion element 12 to rotate about the first rotation axis 103.

In this way, the light conversion part 22 can be rotated by driving the mounting part 23 to rotate, thereby realizing optical anti-shake. Specifically, after detecting the rotation angle, the processor may determine, according to the data, the voltage that should be applied to the first electromagnetic element 282, the first electromagnetic element 282 generates a magnetic field after the voltage is applied, and the third magnetic element 283 receives the magnetic field, so that the mounting portion 23 is driven to rotate to compensate for the shake of the periscopic camera 10. Thus, optical anti-shake can be realized.

A gap 284 is formed between the sensing element 281 and the third magnetic element 283. The dimension B of the gap 284 ranges from 0.20mm to 0.25mm as shown in fig. 6.

In this way, the space in which the third magnetic element 283 and the mounting portion 23 rotate can be avoided, and the third magnetic element 283 and the mounting portion 23 are ensured not to interfere with the sensing element 281 in the rotating process. Specifically, the gap 284 is an air gap.

Preferably, the dimension B of the gap 284 is 0.22mm. In another example, the gap 284 has a size of 0.20mm; in yet another example, the dimension B of the gap 284 is 0.21mm; in yet another example, the dimension B of the gap 284 is 0.25mm. Specific values of the dimension B of the gap 284 are not limited herein.

The driving circuit board 285 is disposed in the lens barrel. Further, a drive circuit board 285 is provided at the bottom wall 216. The first electromagnetic element 282 and the inductive element 281 are both arranged on the drive circuit board 285. That is, the first electromagnetic element 282 and the sensing element 281 are disposed at the bottom wall 216 via the driving circuit board 285.

In this way, the driving circuit board 285 supplies power to the first electromagnetic element 282, and the periscope type camera 20 can be more compact in structure, which is beneficial to miniaturization of the periscope type camera 20. In particular, the drive circuit board 285 may be a flexible circuit board, a printed circuit board, or other type of circuit board.

The drive circuit board 285 may be soldered, glued, etc. to the bottom wall 216. In one example, the driver circuit board 285 may be attached to the bottom wall 216 by an adhesive tape.

In the assembly process, the first electromagnetic element 282 and the sensing element 281 may be fixed on the driving circuit board 285, then the driving circuit board 285 is attached to the bottom wall 216, and finally the bottom wall 216 is assembled to the housing 21. Thus, the assembly is simple and convenient, and the assembly efficiency can be improved.

It should be noted that the drive circuit board 285 is provided at the bottom wall 216 of the lens barrel. The driving circuit board 285 may be fixed in contact with the bottom wall 216 of the housing 21, or the driving circuit board 285 may be fixed to the bottom wall 216 of the housing 21 by other members.

The second electromagnetic element 286 is disposed on the sidewall 214. As shown in the orientation in fig. 8, the second electromagnetic element 286 is provided on the side wall 214 in the X direction of the lens barrel. The fourth magnetic element 287 is disposed at the mounting portion 23. As shown in the orientation of fig. 8, the second electromagnetic element 286 is provided at a portion of the mounting portion 23 in the X direction. The fourth magnetic element 287 cooperates with the second electromagnetic element 286 to drive the light conversion element 12 to rotate about the second rotation axis 104.

Thus, the fourth magnetic element 287 and the second electromagnetic element 286 cooperate to enable the periscope camera to achieve the optical anti-shake effect in the X direction. The second electromagnetic element 286 is, for example, a coil. The fourth magnetic element 287 is, for example, a permanent magnet.

In the present embodiment, the number of the second electromagnetic elements 286 is two, and the second electromagnetic elements are respectively provided on the two side walls 214 in the X direction of the lens barrel. Accordingly, the number of the fourth magnetic elements 287 is two, and they are disposed on both sides of the mounting portion 23X direction. The two second electromagnetic elements 286 cooperate to drive the light converting portion to rotate about the second rotation axis 104. The amount of electromagnetic force formed by the two second electromagnetic elements 286 can be calculated by difference, thereby accurately controlling the angle at which the light-converting portion rotates.

In this embodiment, the housing 21 is a protective element of the periscope type camera 20, so that the impact applied to the first lens assembly 24 can be reduced. In the present embodiment, the housing 21 has a substantially rectangular parallelepiped shape. The housing 21 is connected to the lens barrel 11. Further, the housing 21 and the lens barrel 11 are of an integral structure. Alternatively, the periscope lens 10 is integrated into the periscope camera 20. Of course, in other embodiments, the housing 21 and the barrel 11 are of a split structure.

Referring to fig. 6, the first lens assembly 24 is accommodated in the loading element 25, and further, the first lens assembly 24 is disposed between the light converting portion 22 and the first image sensor 26. The first lens assembly 24 is used to image incident light onto the first image sensor 26. This allows the first image sensor 26 to obtain a better quality image.

The first lens assembly 24, when moved entirely along its optical axis, can be imaged onto the first image sensor 26 to achieve focusing of the periscope camera 20. The first lens assembly 24 includes a plurality of lenses 241, and when at least one lens 241 is moved, the overall focal length of the first lens assembly 24 is changed, thereby achieving a zoom function of the periscope camera 20, and further, the loading element 25 is driven by the driving mechanism 27 to move in the housing 21 for zooming purposes.

In the example of fig. 6, the loading element 25 is cylindrical in shape and a plurality of lenses 241 in the first lens assembly 24 are secured within the loading element 25 at axial intervals along the loading element 25. As in the example of fig. 15, the loading element 25 comprises two clips 252, the two clips 252 sandwiching the lens 241 between the two clips 252.

It will be appreciated that since the loading element 25 is used to fixedly dispose a plurality of lenses 241, the loading element 25 may have a cylindrical shape, a square cylindrical shape, or the like, and the loading element 25 may have a hollow structure having a large length. The loading element 25 is cylindrical, and the loading element 25 can better arrange a plurality of lenses 241 and can better protect the lenses 241 in the cavity, so that the lenses 241 are not easy to shake.

In addition, in the example of fig. 15, the loading element 25 clamps the plurality of lenses 241 between the two clamping pieces 252, so that the loading element 25 has a certain stability, the weight of the loading element 25 can be reduced, the power required by the driving mechanism 27 to drive the loading element 25 can be reduced, the design difficulty of the loading element 25 is low, and the lenses 241 are easy to be arranged on the loading element 25.

Of course, the loading element 25 is not limited to the above-mentioned barrel shape and two clips 252, and in other embodiments, the loading element 25 may comprise three, four, etc. more clips 252 to form a more stable structure, or a simpler structure such as one clip 252; or a rectangular body, a round body, etc. having a cavity to accommodate various regular or irregular shapes of the lens 241. The specific selection is only needed on the premise of ensuring the normal imaging and operation of the camera 10.

The first image sensor 26 may employ a complementary metal oxide semiconductor (CMOS, complementary Metal Oxide Semiconductor) photosensitive element or a Charge-coupled Device (CCD) photosensitive element.

The driving mechanism 27 is an electromagnetic driving mechanism, a piezoelectric driving mechanism, or a memory alloy driving mechanism.

Specifically, in the case where the driving mechanism 27 is an electromagnetic driving mechanism, the driving mechanism 27 includes a magnet for generating a magnetic field and a conductor for driving the loading element 25 to move. When the magnetic field moves relative to the conductor, an induced current is generated in the conductor, causing the conductor to be acted upon by amperes to drive the loading element 25 in motion.

In the case where the driving mechanism 27 is a piezoelectric driving mechanism, a voltage may be applied to the driving mechanism 27 based on the inverse piezoelectric effect of the piezoelectric ceramic material, so that mechanical stress is generated in the driving mechanism 27. That is, the drive mechanism 27 is controlled to mechanically deform by conversion between electric energy and mechanical energy, thereby driving the loading element 25 to move.

In the case where the driving mechanism 27 is a memory alloy driving mechanism, the driving mechanism 27 may be previously caused to memorize a predetermined shape. When it is desired to drive the loading element 25 in motion, the drive mechanism 27 may be heated to a temperature corresponding to the preset shape to return the drive mechanism 27 to the preset shape to drive the loading element 25 in motion.

Referring to fig. 16, in the present embodiment, the first wide-angle camera 30 is a vertical camera, however, in other embodiments, the first wide-angle camera 30 may be a periscopic lens module.

The first wide-angle camera 30 includes a second lens assembly 31 and a second image sensor 32, the second lens assembly 31 is used for imaging light on the second image sensor 32, and an incident optical axis of the first wide-angle camera 30 coincides with an optical axis of the second lens assembly 31.

In this embodiment, the first wide-angle camera 30 may be a fixed focus lens module, so that the second lens assembly 31 has fewer lenses 241, so that the first wide-angle camera 30 has a lower height, which is beneficial to reducing the thickness of the electronic device 1000.

The type of the second image sensor 32 may be the same as the type of the first image sensor 26, and will not be described here.

The second wide-angle camera 40 is similar in structure to the first wide-angle camera 30, for example, the second wide-angle camera 40 is also a vertical camera. Therefore, reference is made to the features of the first wide-angle camera 40 for the features of the second wide-angle camera 40, and detailed descriptions thereof are omitted herein.

In some embodiments, the camera assembly 100 satisfies the following conditions:

f2＜f3＜f1；

1＜f3/f2≤5；

5＜f1/f2≤10；

wherein f1 is the equivalent focal length of the periscope type camera 20, f2 is the equivalent focal length of the first wide-angle camera 30, and f3 is the equivalent focal length of the second wide-angle camera 40.

Thus, the periscope type camera 20 adopts the periscope type imaging module, so that the periscope type camera 20 and the first wide-angle camera 30 can be matched to obtain an optical zooming effect which is more than 5 times. In addition, the first wide-angle camera 30 and the second wide-angle camera 40 can be combined to obtain an optical zoom effect of more than 1 time and less than or equal to 5 times. Thus, the periscope type camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 are matched, so that the camera assembly 100 can realize optical zooming between 1-10 times, and the shooting effect of the camera assembly 100 is improved.

Generally, it is customary in the industry to convert the imaging angle of view of the photosensitive elements with different sizes into a lens focal length corresponding to the same imaging angle of view of a 135 film camera (the photosensitive surface of the 135 film camera is fixed, and the 35mm film specification), and the focal length after conversion is the equivalent focal length of the 135 film camera, that is, the equivalent focal length. Since the size of the photosensitive element (CCD or CMOS) of the digital camera is different from camera to camera (e.g., 1/2.5 inch, 1/1.8 inch, etc.), the imaging angle of view of the lens with the same focal length is different on the digital camera with the photosensitive element of different size. It is the shooting range (view angle size) of the camera that is really significant for the user, i.e. what one is more concerned about is the equivalent focal length rather than the actual focal length.

In one example, f3/f2 is a number of 1.5, 2, 2.5, 3, 4, or 5, etc. That is, the first wide-angle camera 30 and the second wide-angle camera 40 can be combined to achieve 1.5 times, 2 times, 2.5 times, 3 times, 4 times, or 5 times optical zoom. Preferably, in one example, 1 < f 3/f2.ltoreq.3. The f1/f2 can be a specific value of 6, 7,8, 9 or 10. Alternatively, the periscope type camera 20 and the first wide angle camera 30 may be combined by 6 times, 7 times, 8 times, 9 times, or 10 times.

When f1/f2 is greater than 10, the effective focal length f1 of the periscope type camera 20 is larger, which also makes the size of the first image sensor larger, resulting in larger size of the periscope type camera 20, which is not beneficial to the design of the electronic device 1000. Therefore, the optical zoom multiple of the camera assembly 100 is controlled within 10 times, so as to not only meet the photographing requirement of the user, but also ensure the light and thin electronic device 1000.

In one embodiment, the first wide angle camera 30 is a primary camera. In other words, in a general photographing case, the first wide-angle camera 30 is turned on to perform photographing. The periscope type camera 20 and the second wide-angle camera 40 can be used as auxiliary cameras, and when a user needs to enlarge image shooting, the periscope type camera 20 or the second wide-angle camera 40 is started.

In one example, f3/f2=2, f1/f2=10. At this time, the camera assembly 100 may achieve a 1-fold, 2-fold, or 10-fold optical zoom effect. When a user turns on the photographing function of the electronic device 1000, the first wide-angle camera 30 is turned on to acquire a pre-photographed scene; when the user selects 2-time magnification effect in the pre-photographed scene, the first wide-angle camera 30 is turned off and the second wide-angle camera 40 is turned on, so that the second wide-angle camera 40 can obtain the photographed scene with 2-time magnification; when the user selects the 10-time magnification effect in the pre-photographed subject, the first wide-angle camera 30 is turned off and the periscope type camera 20 is turned on, so that the periscope type camera 20 can acquire the photographed subject magnified 10 times. Thus, it can be appreciated that since the image magnification of the pre-shot scene is obtained by optical zooming, the camera assembly 100 can obtain an image of the pre-shot scene with better quality.

In one embodiment, the combination of periscopic camera 20, first wide angle camera 30, and second wide angle camera 40 of camera assembly 100 is shown in table one below:

Table one:

in this embodiment, the optical transformation ratio refers to the ratio of the equivalent focal length of the other imaging modules to the equivalent focal length of the first wide-angle camera 30.

In another embodiment, the combination of periscopic camera 20, first wide angle camera 30, and second wide angle camera 40 of camera assembly 100 is shown in table two below:

and (II) table:

in yet another embodiment, the combination of periscopic camera 20, first wide angle camera 30, and second wide angle camera 40 of camera assembly 100 is shown in table three below:

Table three:

it should be noted that, the number of the second wide-angle cameras 40 may be plural, as shown in the above table one, table two and table three, and the plurality of second wide-angle cameras 40 may enable the first wide-angle camera 30 and the second wide-angle camera 40 to be matched to achieve more zoom multiples, which is beneficial to improving the shooting effect of the electronic device 1000.

In some embodiments, the periscope cameras 20 are multiple in number, and the equivalent focal lengths of the multiple periscope cameras 20 are different. That is, the number of imaging modules of the camera assembly 100 may be greater than 3. In this manner, camera assembly 100 may achieve multiple optical zoom factors between 5-10 times.

In one example, the number of periscope cameras 20 is 3, which are periscope camera I, periscope camera I I, and periscope camera III, respectively, wherein the ratio of the equivalent focal length of periscope camera I to the equivalent focal length of first wide-angle camera 30 is about 7, the ratio of the equivalent focal length of periscope camera II to the equivalent focal length of first wide-angle camera 30 is about 9, and the ratio of the equivalent focal length of periscope camera III to the equivalent focal length of first wide-angle camera 30 is about 10. Alternatively, periscopic camera I cooperates with first wide angle camera 30 to achieve 7 times optical zoom of camera assembly 100. Periscopic camera II cooperates with first wide angle camera 30 to achieve 9 x optical zoom of camera assembly 100. Periscopic camera III cooperates with first wide angle camera 30 to achieve a 10 x optical zoom for camera assembly 100.

In one embodiment, the combination of periscopic camera 20, first wide angle camera 30, and second wide angle camera 40 of camera assembly 100 is shown in table four below:

Table four:

In some embodiments, the resolution of periscopic camera 20 is the same as the resolution of first wide angle camera 30. Thus, under the same resolution, the periscope type camera 20 and the first wide-angle camera 30 cooperate to realize optical zooming of more than 5 times, so that the image quality of the amplified pre-shot scenery is better.

In one example, the resolution of periscope camera 20 and the resolution of first wide angle camera 30 are both 8M.

Of course, in other embodiments, the resolution of periscopic camera 20 and the resolution of first wide angle camera 30 may be different. For example, the resolution of the periscope type camera 20 is 12M, and the resolution of the first wide angle camera 30 is 8M.

In some embodiments, the resolution of second wide angle camera 40 is greater than or equal to 8M.
