Detailed ways

The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

1 , the electronic device 1000 of the embodiment of the present application includes a housing 110 , a camera assembly 100 , and a battery 120 . The camera assembly 100 is disposed in the housing 110 and exposed through the housing 110 . The battery 120 is disposed in the housing 110 .

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

Specifically, the electronic device 1000 can be a mobile phone or a smart phone (for example, a phone based on the iPhone system or the Android system), a portable gaming device (for example, an iPhone), a laptop computer, a personal digital assistant (PDA), a portable Internet device, a music player, and a data storage device, other handheld devices, and devices such as watches, in-ear headphones, pendants, headphones, etc.

The electronic device 100 may also be other wearable devices (for example, a head mount display (HMD) such as electronic glasses, electronic clothes, electronic bracelets, electronic necklaces, electronic tattoos, electronic devices, or smart watches).

The housing 110 is an external component of the electronic device 1000, which plays a role in protecting the internal components of the electronic device 1000. The housing 110 may be a back cover of the electronic device 1000, which covers components of the electronic device 1000 such as the battery 120.

In this embodiment, the camera assembly 100 is rear-mounted, or in other words, the camera assembly 100 is disposed on the back of the electronic device 1000 so that the electronic device 1000 can perform rear-facing camera shooting. As shown in the example of FIG1 , the camera assembly 100 is disposed in the upper middle position of the housing 110. The battery 120 is disposed at the lower part of the electronic device 1000. In other words, the camera assembly 100 and the battery 120 are disposed at intervals along the longitudinal direction of the electronic device 1000. In this way, the camera assembly 100 and the battery 120 can avoid being stacked in the thickness direction of the electronic device 1000, which can reduce the thickness of the electronic device 1000 and prevent the camera assembly 100 and the battery 120 from interfering.

Of course, it is understood that the camera assembly 100 can be disposed at other positions such as the upper left position or the upper right position of the housing 110. The position where the camera assembly 100 is disposed at the housing 110 is not limited to the example of the present application.

Please refer to FIG. 2 and FIG. 3 , the camera assembly 100 includes a periscope camera 20 , a first wide-angle camera 30 , a second wide-angle camera 40 , a bracket 50 and a flash 60 .

The periscope camera 20, the first wide-angle camera 30, and the second wide-angle camera 40 are all disposed in the bracket 50 and fixedly connected to the bracket 50. The bracket 50 can reduce the impact on the periscope camera 20, the first wide-angle camera 30, and the second wide-angle camera 40, and improve the life of the periscope camera 20, the first wide-angle camera 30, and the second wide-angle camera 40.

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

It should be noted that the wide-angle camera mentioned in this embodiment means that the field of view of the camera is greater than 60 degrees.

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

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

Since the field of view FOV1 of the periscope camera 20 is small, it can be understood that the focal length of the periscope camera 20 is large, so the periscope camera 20 can be used to shoot a distant view, thereby obtaining a clear distant image. The field of view FOV2 of the first wide-angle camera 30 is large, and it can be understood that the focal length of the first wide-angle camera 30 is short, so the first wide-angle camera 30 can be used to shoot a close view, thereby obtaining a partial close-up image of an object. The second wide-angle camera 40 can be used to shoot an object normally.

In this way, through the combination of the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40, image effects such as background blur and local sharpening of the picture can be obtained.

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

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

In other words, please refer to Figure 3, the periscope camera 20 is used to deflect the light entering from the light input axis 101 of the periscope camera 20 to the imaging optical axis 102 of the periscope camera 20 which is basically perpendicular to the light input axis 101 of the periscope camera 20 and form an image, the light input axis 101 of the periscope camera 20 is basically 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, and the imaging optical axis 102 is basically perpendicular to the arrangement direction of the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40.

In this way, the light input axis 101 of the periscope camera 20 is basically 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, and the imaging optical axis 102 of the periscope camera 20 is basically perpendicular to the arrangement direction of the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40. This can avoid the camera assembly 100 from being larger in a single direction, and avoid interference with other components of the electronic device 1000 when the camera assembly 100 is applied to an electronic device 1000 such as a mobile phone, which is beneficial to the layout of other components of the electronic device 1000.

It should be noted that the light entering from the light input axis 101 of the periscope camera 20 refers to the light entering the periscope camera 20 with the light input axis 101 as the center. The light can be parallel to the light input axis 101 or form a certain angle with the light input axis 101.

In addition, the light rays turning toward the imaging optical axis 102 refer to the light rays propagating with the imaging optical axis 102 as the center. The light rays may be parallel to the imaging optical axis 102 or may form a certain angle with the imaging optical axis 102 .

It can be understood that if the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 are arranged in a "one" shape, then the size of the camera assembly 100 in the direction where the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 are arranged is relatively large, which is not conducive to the installation of the camera assembly 100 into the electronic device.

In addition, please refer to Figure 1. In this embodiment, the light inlet 211 of the periscope 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 used for the longitudinal arrangement along the electronic device 1000, and the length direction of the periscope camera 20 is used for the lateral arrangement along the electronic device 1000.

In other words, when the camera assembly 100 is applied to the electronic device 1000, the light inlet 211 of the periscope 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 camera 20 is arranged along the transverse direction of the electronic device 1000.

Furthermore, the optical axis 101 of the periscope camera 20 is arranged coplanar with the optical axes of the first wide-angle camera 30 and the second wide-angle camera 40. This is conducive to simplifying the image algorithm, thereby making it easier to obtain images of better quality.

Due to the field of view of the periscope camera 20 and the second wide-angle camera 40, in order to enable the periscope camera 20 and the second wide-angle camera 40 to obtain images of better quality, the periscope camera 20 and the second wide-angle camera 40 can be configured with an optical image stabilization device, and the optical image stabilization device is generally configured with more magnetic elements. Therefore, the periscope camera 20 and the second wide-angle camera 40 can generate a magnetic field.

In the present embodiment, the first wide-angle camera 30 is located between the periscope camera 20 and the second wide-angle camera 40, so that the periscope camera 20 and the second wide-angle camera 40 can be kept away from each other, thereby preventing the magnetic field formed by the periscope camera 20 and the magnetic field formed by the second wide-angle camera 40 from interfering with each other and affecting the normal use of the periscope camera 20 and the second wide-angle camera 40.

The periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 can be arranged at intervals, and two adjacent cameras can also be close to each other.

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

It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

Please refer to Figures 4-6. In this embodiment, the periscope camera 20 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 and the loading element 25 are both disposed in the housing 21. The first lens assembly 24 is fixed on the loading element 25. The loading element 25 is disposed on one side of the first image sensor 26. Further, the loading element 25 is located between the periscope lens 10 and the first image sensor 26.

The driving mechanism 27 connects the loading element 25 and the housing 21. After the incident light enters the periscope camera 20, it is deflected by 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 driving mechanism 27 is used to drive the loading element 25 to move along the optical axis of the first lens assembly 24 so that the first lens assembly 24 focuses on the first image sensor 26 to form an image.

Referring to FIG. 7 and FIG. 8 , in this embodiment, the periscope lens 10 includes a lens barrel 11, a light-transmitting element 12, and a two-axis hinge 13. The light-transmitting element 12 is disposed in the lens barrel 11. The light-transmitting element 12 is used to transfer light from the light-incoming axis 101 to the imaging light axis 102, and the imaging light axis 102 is perpendicular to the light-incoming axis 101. In other words, the light-transmitting element 12 is used to transfer light from the light-incoming axis 101 to the first image sensor 26.

The two-axis hinge 13 rotatably connects the lens barrel 11 and the light deflection element 12. The two-axis hinge 13 includes a first rotation axis 103 and a second rotation axis 104, wherein the first rotation axis 103 is perpendicular to the light input axis 101 and the imaging optical axis 102, and the second rotation axis 104 is parallel to the light input axis 101.

In this way, the first rotating shaft 103 and the second rotating shaft 104 of the two-axis hinge 13 can enable the light-deflecting element 12 to rotate in two directions, and the rotation accuracy of the light-deflecting element 12 is high, so that the camera with the periscope lens 10 can achieve a better optical image stabilization effect in two directions. In addition, the structure of the two-axis hinge 13 is compact, which can reduce the volume of the periscope lens 10.

It can be understood that the periscope camera 20 is a periscope lens module. Compared with the vertical lens module, the height of the periscope lens module is smaller, so that the overall thickness of the electronic device 1000 can be reduced. The vertical lens module refers to the imaging optical axis and the light input axis of the lens module being a straight line. In other words, the incident light is transmitted to the photosensitive device of the lens module along the direction of the straight optical axis.

Specifically, the lens barrel 11 is roughly in a square shape. The lens barrel 11 can be made of materials such as plastic and metal. The lens barrel 11 has a light inlet 211, and the incident light enters the periscope lens 10 from the light inlet 211. In other words, the light deflection element 12 is used to deflect the incident light incident from the light inlet 211 and transmit it to the first image sensor 26 after passing through the first lens assembly 24 so that the first image sensor 26 senses the incident light outside the periscope camera 20.

5 and 7, the lens barrel 11 includes a top wall 213, a side wall 214 and a bottom wall 216. The side wall 214 is formed by extending from the side edge 2131 of the top wall 213. The bottom wall 216 is opposite to the top wall 213. The top wall 213 is formed with a light inlet 211, or in other words, the light inlet 211 is formed in the top wall 213. The top wall 213 includes two side edges 2131 facing each other. There are two side walls 214, and each side wall 214 extends from a corresponding side edge 2131. In other words, the side walls 214 are respectively connected to the two sides of the top wall 213 facing each other.

The light deflecting element 12 includes a light deflecting portion 22 and a mounting portion 23. The light deflecting portion 22 is disposed on the mounting portion 23. The light deflecting portion 22 can be fixed to the mounting portion 23 by adhesive bonding to achieve fixed connection with the mounting portion 23.

The light deflection part 22 is a prism or a plane mirror. In one example, when the light deflection part 22 is a prism, the prism can be a triangular prism, and the cross section of the prism is a right triangle, wherein the light is incident from one of the right-angled faces of the right triangle, and then emerges from the other right-angled face after reflection.

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

It can be understood that when the light deflecting portion 22 is a plane mirror, the plane mirror reflects the incident light to achieve deflection of the incident light.

For more information, please refer to FIG. 7 and FIG. 9 . The light deflection portion 22 has a light incident surface 222, a backlight surface 224, a light deflection surface 226, and a light emitting surface 228. The light incident surface 222 is close to and faces the light inlet 211. The backlight surface 224 is away from the light inlet 211 and faces away from the light incident surface 222. The light deflection surface 226 connects the light incident surface 222 and the backlight surface 224. The light emitting surface 228 connects the light incident surface 222 and the backlight surface 224. The light emitting surface 228 faces the first image sensor 26. The light deflection surface 226 is tilted relative to the light incident surface 222. The light emitting surface 228 faces away from the light deflection surface 226.

Specifically, during the light redirection process, the light passes through the light inlet 211 and enters the light redirecting portion 22 from the light incident surface 222, then redirects through the light redirecting surface 226, and finally reflects out of the light redirecting portion 22 from the light emitting surface 228, completing the light redirection process. The backlight surface 224 is fixedly arranged with the mounting portion 23 to keep the light redirecting portion 22 stable.

As shown in FIG10 , in the related art, due to the need to reflect incident light, the light deflection surface 226a of the light deflection portion 22a is inclined relative to the horizontal direction, and the light deflection portion 22a is an asymmetric structure in the direction of light reflection. Therefore, the actual optical area below the light deflection portion 22a is smaller than that above the light deflection portion 22a. This can be understood as the part of the light deflection surface 226a away from the light inlet reflects less or no light.

Therefore, referring to FIG. 11 , the light deflecting portion 22 of the embodiment of the present application cuts off the corners away from the light inlet compared to the light deflecting portion 22a in the related art. This not only does not affect the light reflecting effect of the light deflecting portion 22 , but also reduces the overall thickness of the light deflecting portion 22 .

Please refer to Fig. 7 again, the light deflection surface 226 is inclined at an angle α of 45 degrees relative to the light incident surface 222. In this way, the incident light is better reflected and converted, and a better light conversion effect is achieved.

Furthermore, the light deflection portion 22 can be made of a material with good light transmittance, such as glass or plastic. In one embodiment, a reflective material such as silver can be coated on one surface of the light deflection portion 22 to reflect the incident light. Of course, the light deflection portion 22 can realize the deflection of the incident light by using the principle of total reflection of light. In this case, there is no need to coat the light deflection portion 22 with a reflective material.

As shown in the example of FIG7 , the light incident surface 222 is arranged parallel to the backlight surface 224. In this way, when the backlight surface 224 and the mounting portion 23 are fixedly arranged, the light deflection portion 22 can be kept stable, the light incident surface 222 is also presented as a plane, and the incident light also forms a regular light path in the conversion process of the light deflection portion 22, so that the light conversion efficiency is better.

Specifically, along the light incident direction of the light inlet 211, the cross section of the light deflection portion 22 is roughly trapezoidal, or in other words, the light deflection portion 22 is roughly trapezoidal. As shown in the example of FIG7 , the light incident surface 222 and the backlight surface 224 are both perpendicular to the light exit surface 228. In this way, a relatively regular light deflection portion 22 can be formed, so that the optical path of the incident light is relatively straight, thereby improving the light conversion efficiency.

In one example, the distance between the light incident surface 222 and the backlight surface 224 is in the range of 4.8-5.0 mm. For example, the distance between the light incident surface 222 and the backlight surface 224 can be 4.85 mm, 4.9 mm, 4.95 mm, etc. In other words, the distance between the light incident surface 222 and the backlight surface 224 can be understood as the height of the light deflection portion 22 is 4.8-5.0 mm.

The light deflection portion 22 formed by the light incident surface 222 and the backlight surface 224 in the above distance range has a moderate volume and can be well fitted into the periscope camera 20, forming a more compact and miniaturized periscope camera 20, camera assembly 100 and electronic device 1000 to meet more demands of consumers.

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

When the light deflecting portion 22 is made of glass or other materials, the material of the light deflecting portion 22 itself is relatively brittle. In order to improve the strength of the light deflecting portion 22, a hardening treatment may be performed on the light incident surface 222, the backlight surface 224, the light deflecting surface 226, and the light emitting surface 228 of the light deflecting portion 22. Furthermore, all surfaces of the light deflecting element 12 may be hardened to further improve the strength of the light deflecting element 12.

Furthermore, the hardening treatment may be to infiltrate lithium ions, or to apply a film to each of the above surfaces without affecting the light conversion of the light conversion unit 22 .

In one example, the angle at which the incident light incident from the light inlet 211 is redirected by the light redirecting unit 22 is 90 degrees. For example, the incident angle of the incident light on the emitting surface of the light redirecting unit 22 is 45 degrees, and the reflection angle is also 45 degrees. Of course, the angle at which the incident light is redirected by the light redirecting unit 22 can also be other angles, such as 80 degrees, 100 degrees, etc., as long as the incident light can be redirected to reach the first image sensor 26.

In this embodiment, there is one light deflection unit 22, and the incident light is deflected once before being transmitted to the first image sensor 26. In other embodiments, there are multiple light deflection units 22, and the incident light is deflected at least twice before being transmitted to the first image sensor 26.

The mounting portion 23 is used to mount the light deflecting portion 22, or in other words, the mounting portion 23 is a carrier of the light deflecting portion 22. The light deflecting portion 22 is fixed on the mounting portion 23. In this way, the position of the light deflecting portion 22 can be determined, which is beneficial for the light deflecting portion 22 to reflect or refract the incident light.

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

In this way, the limiting structure 232 limits the position of the light deflecting portion 22 on the mounting portion 23, so that the light deflecting portion 22 will not be displaced when it is hit, which is beneficial to the normal use of the periscope camera 20.

It can be understood that in one example, the light deflecting portion 22 is fixed to the mounting portion 23 by bonding. If the limiting structure 232 is omitted, then when the periscope camera 20 is impacted, if the bonding force between the light deflecting portion 2222 and the mounting portion 23 is insufficient, the light deflecting portion 22 may easily fall off from the mounting portion 23.

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

In this way, the receiving groove 233 can make it easy for the light deflecting part 22 to be installed on the mounting part 23. The limiting structure 232 is arranged at the edge of the receiving groove 233 and abuts against the edge of the light deflecting part 22, which can not only limit the position of the light deflecting part 22, but also will not hinder the light deflecting part 22 from emitting the incident light to the first image sensor 26.

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

Since the light deflecting portion 22 is mounted on the mounting portion 23 via the light deflecting surface 226, and the light emitting surface 228 is disposed opposite to the light deflecting surface 226, the light deflecting portion 22 is more likely to move toward the side of the light emitting surface 228 when impacted. In this embodiment, the limiting structure 232 abuts against the edge of the light emitting surface 228, which can not only prevent the light deflecting portion 22 from moving toward the side of the light emitting surface 228, but also ensure that light can be normally emitted from the light emitting surface 228.

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

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

Of course, in other embodiments, the protrusion 234 may also be in a block shape or other structures.

It can be understood that the mounting portion 23 can drive the light deflection portion 22 to rotate in the opposite direction of the shaking of the periscope camera 20, thereby compensating for the incident deviation of the incident light of the light inlet 211 and achieving the effect of optical image stabilization.

Referring to FIGS. 6 to 8 , in this 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 limiting structure 15 is used to limit the degree of freedom of the light-deflecting element 12 and the connecting member 14 in the direction of the imaging optical axis 102. The first rotating member 16 rotatably connects the lens barrel 11 and the connecting member 14. The first rotating member 16 forms a first rotating shaft 103. The second rotating member 17 rotatably connects the light-deflecting element 12 and the connecting 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 the rotation of the light conversion element 12 in two directions. Specifically, the first rotating member 16 is formed with a first rotating shaft 103, so that the light conversion element 12 can rotate around the first rotating shaft 103 through the connecting member 14. The second rotating member 17 is formed with a second rotating shaft 104, so that the light conversion element 12 can rotate around the second rotating shaft 104.

5 to 7 , for the convenience of description, the width direction of the periscope 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 light input axis 101 extends along the Y direction, the imaging optical axis 102 extends along the Z direction, the first rotation axis 103 extends along the X direction, and the second rotation axis 104 extends along the Y direction.

That is to say, the light deflection element 12 can be rotated around the X direction by the first rotating member 16, so that the periscope camera 20 can achieve optical image stabilization in the Y direction. In addition, the light deflection element 12 can be rotated around the Y direction by the second rotating member 17, so that the periscope camera 20 can achieve optical image stabilization in the X direction.

Of course, in other embodiments, the first rotating member 16 can form the second rotating shaft 104, and the second rotating member 17 can form the first rotating shaft 103. In other words, the periscope camera 20 can achieve optical image stabilization in the X direction through the first rotating member 16, and the periscope camera 20 can achieve optical image stabilization in the Y direction through the second rotating member 17.

In this embodiment, the connector 14 can be in a square shape, an irregular shape, etc. In addition, the connector 14 can be made of materials such as plastic and metal. In order to reduce the weight of the periscope lens 10, the connector 14 can be made of a material with a lower density. Therefore, in the embodiment of the present application, the shape and material of the connector 14 are not limited.

The limiting structure 15 can limit the degree of freedom of the connecting member 14 and the light deflecting element 12 in the Z direction, thereby preventing the connecting member 14 and the light deflecting element 12 from falling apart.

Please refer to FIG. 7 . In one 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 , and the second magnetic element 152 is disposed on the light deflecting element 12 . The first magnetic element 151 and the second magnetic element 152 attract each other.

In this way, the magnetic elements attract each other, thereby limiting the degree of freedom of the connecting member 14 and the light-converting element 12 in the Z direction. Specifically, the lens barrel 11 is formed with a first mounting groove 112. The first magnetic element 151 is disposed in the first mounting groove 112. The light-converting element 12 is formed with a second mounting groove 122, and the second magnetic element 152 is disposed in the second mounting groove 122. In this way, the structure among the limiting structure 15, the lens barrel 11 and the light-converting element 12 is more compact, thereby reducing the volume of the periscope lens.

In this embodiment, the first mounting groove 112 is formed on the side wall 214 of the lens barrel 11 , and the second mounting groove 122 is formed on the mounting portion 23 .

8 , in another example, the limiting structure 15 includes a first flexible element 153 and a second flexible element 154, wherein 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-deflecting element 12. The first flexible element 153 and the second flexible element 154 are, for example, elastic elements such as metal wires and plastic parts.

As shown in FIGS. 7 and 8 , in this embodiment, the connecting member 14 and the lens barrel 11 jointly define a first receiving space 141, and the first rotating member 16 is disposed in the first receiving space 141. In addition, the light-converting element 12 and the connecting member 14 jointly define a second receiving space 142, and the second rotating member 17 is disposed in the second receiving space 142. The first receiving space 141 and the second receiving space 142 can make the structure of the two-axis hinge 13 more compact, thereby reducing the volume of the periscope lens 10.

Specifically, the connecting member 14 and the side wall 214 jointly define a first receiving space 141. The connecting member 14 and the mounting portion 2323 jointly define a second receiving space 142. The first receiving space 141 and the second receiving space 142 may be cylindrical or spherical.

The first rotating member 16 is rotatably connected to the side wall 214 and the connecting member 14. The first rotating member 16 includes a roller and/or a ball. In other words, the first rotating member 16 can be a roller, or a ball, or the first rotating member 16 includes a roller and a ball. It can be understood that the roller is in the shape of an elongated strip. The ball is in the shape of a sphere. The first rotating member 16 can be made of metal or plastic. In order to reduce the friction of the first rotating member 16, the surface of the first rotating member 16 can be provided with a film layer made of a low friction coefficient such as polytetrafluoroethylene.

There are multiple first rotating members 16, and the multiple first rotating members 16 are arranged at intervals along the first rotating shaft 103. For example, the number of the first rotating members 16 is 2, 3, or 4. As mentioned above, it can be understood that some of the first rotating members 16 can be rollers, and another part of the first rotating members 16 can be balls.

The second rotating member 17 is rotatably connected to the mounting portion 23 and the connecting member 14. The second rotating member 17 includes a roller and/or a ball. In other words, the second rotating member 17 can be a roller, or a ball, or the second rotating member 17 includes a roller and a ball. It can be understood that the roller is in the shape of an elongated strip. The ball is in the shape of a sphere. The second rotating member 17 can 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 can be provided with a film layer made of a low friction coefficient such as polytetrafluoroethylene.

There are multiple second rotating members 17, and the multiple second rotating members 17 are arranged at intervals along the second rotating shaft 104. For example, the number of the second rotating members 17 is 2, 3, or 4. As mentioned above, it can be understood that some of the second rotating members 17 can be rollers, and another part of the second rotating members 17 can be balls.

Please refer to FIG. 7 and FIG. 9 again. Further, the periscope lens further includes a driving device 28 , and the driving device 28 is used to drive the mounting portion 23 with the light deflecting portion 22 to rotate around the first rotating shaft 103 and the second rotating shaft 104 .

In this way, the driving device 28 drives the mounting portion 23 to move in two directions, which can not only achieve the optical image stabilization effect of the periscope camera 20 in two directions, but also make the volume of the periscope camera 20 smaller.

The driving device 28 drives the mounting portion 23 to rotate, so that the light deflection portion 22 rotates around the X direction, so that the periscope camera 20 achieves the effect of optical image stabilization in the Y direction. In addition, the driving device 28 drives the mounting portion 23 to move axially along the rotation axis 29, so that the periscope camera 20 achieves the effect of optical image stabilization in the X direction. In addition, the first lens assembly 24 can be along the Z direction to achieve the focus of the first lens assembly 24 on the first image sensor 26.

Specifically, when the light deflecting portion 22 rotates about the X direction, the light reflected by the light deflecting portion 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 deflecting portion 22 moves along the X direction, the light deflected by the light deflecting portion 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.

Please refer to FIGS. 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 to detect the rotation angle of the light deflecting part 22. The first electromagnetic element 282 is arranged on one side of the light deflecting part 22. The first electromagnetic element 282 is used to drive the light deflecting part 22 to rotate according to the data detected by the sensing element 281 so that the periscope camera 20 can achieve optical image stabilization.

Furthermore, the first electromagnetic element 282 is used to drive the mounting portion 23 to rotate according to the data detected by the sensing element 281 so as to drive the light deflecting portion 22 to rotate.

Optionally, 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.

In this way, the sensing element 281 is arranged on the outside of the first electromagnetic element 282. When the position of the sensing element 281 is shifted during the assembly process, a large deviation of the detected sensing data can be avoided. While ensuring that the sensing element 281 participates normally in the optical image stabilization, the accuracy of the data collected by the sensing element 281 can be improved, which is beneficial to improving the accuracy of the optical image stabilization.

The related technology generally sets the Hall sensor in the center of the coil so that the initial value of the Hall sensor is 0, thereby maximizing the range of the Hall sensor. However, during the assembly process of each component, the position of the component will shift, resulting in errors in the data measured by the Hall sensor. For example, the Hall sensor is set in the center of the coil, and the initial value of the Hall sensor is 0mv. After assembly, the position shift causes the Hall sensor to actually have a deviation of 10mv. At this time, the impact caused by the deviation is 100%.

If the Hall sensor is placed outside the coil, the Hall sensor will have a non-zero initial value, which can reduce the impact of the deviation. For example, after the Hall sensor is placed outside the coil, the initial value of the Hall sensor is 140mv. After assembly, the position offset causes the Hall sensor to actually have a 10mv deviation. At this time, the impact of the deviation is 7%.

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

Please refer to FIG. 13 and FIG. 14 , in which the U direction is defined as the direction in which the light deflecting portion 22 moves along the X direction, and the V direction is the direction in which the light deflecting portion 22 rotates around the X direction.

Figure 13 is a simulation result of the deviation rate of the Hall sensor in the U direction and the V direction in the related art. Figure 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. Among them, the horizontal axis is the deviation rate, and the vertical axis is the number of samples falling into the corresponding deviation rate. Deviation rate (%) = ((actual value - center value) / range of Hall sensor) × 100%. The range of the Hall sensor is within the range of ±1.5°.

As can be seen from Figures 13 and 14, compared with the prior art, the present application has more concentrated data in the V direction, that is, the deviation rate is smaller. Furthermore, the present 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.

12 , the first electromagnetic element 282 is disposed on the bottom wall 216. The first electromagnetic element 282 is annular and has a first center line 2821. The sensing element 281 is disposed offset from the first center line 2821. 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 0.5 mm to 1.0 mm.

When 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 0.5 mm to 1.0 mm, the initial value after the offset is more appropriate. It can be understood that the initial value after the offset cannot be too small, otherwise the deviation rate cannot be further reduced; the initial value after the offset cannot be too large, otherwise the range of the Hall sensor will be insufficient.

Preferably, the distance between the center of the sensing element 281 and the first center line 2821 of the first electromagnetic element 282 is 0.75 mm.

In another example, the distance A between the center of the sensing element 281 and the first center line 2821 of the first electromagnetic element 282 is 0.5 mm; in another example, the distance A between the center of the sensing element 281 and the first center line 2821 of the first electromagnetic element 282 is 0.8 mm; in yet another example, the distance A between the center of the sensing element 281 and the first center line 2821 of the first electromagnetic element 282 is 1 mm. The specific value of the distance A between the center of the sensing element 281 and the first center line 2821 of the first electromagnetic element 282 is not limited herein.

It can be understood that the first electromagnetic element 282 can also be circular, square or any other shape, and the specific shape of the first electromagnetic element 282 is not limited here.

In addition, in the example of FIG12 , the sensing element 281 is located on one side of the first electromagnetic element 282. It can be understood that in other examples, the sensing element 281 can 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 camera 20, the specific position of the sensing element 281 is not limited herein.

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

In this way, the data measured by the first electromagnetic element 282 can be made more accurate. Specifically, the data output by the two first electromagnetic elements 282 can be calculated, such as averaging, to obtain more accurate data. In addition, when one of the first electromagnetic elements 282 is abnormal, the other first electromagnetic element 282 can also be used to ensure the normal operation of the optical image stabilization, which is beneficial to improve the reliability of the driving device 28.

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

The third magnetic element 283 is disposed on the light deflecting 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 deflecting element 12 to rotate around the first rotating shaft 103 .

In this way, the light deflection part 22 can be rotated by driving the mounting part 23 to rotate, thereby achieving optical image stabilization. Specifically, after the sensing element 281 detects the rotation angle, the processor can determine the voltage to be applied to the first electromagnetic element 282 according to the data. The first electromagnetic element 282 generates a magnetic field after the voltage is applied, and the third magnetic element 283 is affected by the magnetic field, thereby driving the mounting part 23 to rotate to compensate for the shaking of the periscope camera 10. In this way, optical image stabilization can be achieved.

A gap 284 is formed between the sensing element 281 and the third magnetic element 283. The size B of the gap 284 ranges from 0.20 mm to 0.25 mm, as shown in FIG6 .

In this way, a space for the third magnetic element 283 and the mounting portion 23 to rotate can be avoided, ensuring that the third magnetic element 283 and the mounting portion 23 will not interfere with the sensing element 281 during the rotation process. Specifically, the gap 284 is an air gap.

Preferably, the dimension B of the gap 284 is 0.22 mm. In another example, the dimension B of the gap 284 is 0.20 mm; in another example, the dimension B of the gap 284 is 0.21 mm; in another example, the dimension B of the gap 284 is 0.25 mm. The specific value of the dimension B of the gap 284 is not limited here.

The driving circuit board 285 is disposed in the lens barrel. Further, the driving circuit board 285 is disposed on the bottom wall 216. The first electromagnetic element 282 and the sensing element 281 are both disposed on the driving circuit board 285. That is, the first electromagnetic element 282 and the sensing element 281 are disposed on the bottom wall 216 through the driving circuit board 285.

In this way, while ensuring that the driving circuit board 285 supplies power to the first electromagnetic element 282, the structure of the periscope camera 20 can be made more compact, which is conducive to the miniaturization of the periscope camera 20. Specifically, the driving circuit board 285 can be a flexible circuit board, a printed circuit board or other types of circuit boards.

The driving circuit board 285 can be attached to the bottom wall 216 by welding, bonding, etc. In one example, the driving circuit board 285 can be attached to the bottom wall 216 by adhesive tape.

During the assembly process, the first electromagnetic element 282 and the inductive element 281 can be first fixed to the driving circuit board 285, and 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. This is simple and convenient, and can improve the efficiency of assembly.

It should be noted that the driving circuit board 285 is disposed on the bottom wall 216 of the lens barrel, which may refer to the driving circuit board 285 being in contact with and fixed to the bottom wall 216 of the housing 21, or the driving circuit board 285 being fixedly connected to the bottom wall 216 of the housing 21 through other components.

The second electromagnetic element 286 is disposed on the side wall 214. As shown in the orientation in FIG8 , the second electromagnetic element 286 is disposed on the side wall 214 of the lens barrel in the X direction. The fourth magnetic element 287 is disposed on the mounting portion 23. As shown in the orientation in FIG8 , the second electromagnetic element 286 is disposed on the mounting portion 23 in the X direction. The fourth magnetic element 287 cooperates with the second electromagnetic element 286 to drive the light-deflecting element 12 to rotate around the second rotating shaft 104.

In this way, the fourth magnetic element 287 cooperates with the second electromagnetic element 286 so that the periscope camera can achieve an optical image stabilization 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 this embodiment, the number of the second electromagnetic elements 286 is two, which are respectively arranged on the two side walls 214 of the lens barrel in the X direction. Correspondingly, the number of the fourth magnetic elements 287 is two, which are respectively arranged on both sides of the mounting portion 23 in the X direction. The two second electromagnetic elements 286 cooperate to drive the light deflection portion to rotate around the second rotating shaft 104. The electromagnetic quantity formed by the two second electromagnetic elements 286 can be calculated by difference, so as to accurately control the rotation angle of the light deflection portion.

In this embodiment, the housing 21 is a protective element of the periscope camera 20, which can reduce the impact on the first lens assembly 24. In this embodiment, the housing 21 is roughly in the shape of a rectangular parallelepiped. The housing 21 is connected to the lens barrel 11. Further, the housing 21 and the lens barrel 11 are an integrated structure. In other words, the periscope lens 10 is integrated into the periscope camera 20. Of course, in other embodiments, the housing 21 and the lens barrel 11 are split structures.

6 , the first lens assembly 24 is received in the loading element 25. Furthermore, the first lens assembly 24 is disposed between the light deflection unit 22 and the first image sensor 26. The first lens assembly 24 is used to image the incident light onto the first image sensor 26. In this way, the first image sensor 26 can obtain an image with better quality.

When the first lens assembly 24 moves as a whole along its optical axis, an image can be formed on the first image sensor 26, thereby realizing the focusing of the periscope camera 20. The first lens assembly 24 includes a plurality of lenses 241. When at least one lens 241 moves, the overall focal length of the first lens assembly 24 changes, thereby realizing the zoom function of the periscope camera 20. Furthermore, the driving mechanism 27 drives the loading element 25 to move in the housing 21 to achieve the zoom purpose.

In the example of Fig. 6, the loading element 25 is cylindrical, and the plurality of lenses 241 in the first lens assembly 24 are fixed in the loading element 25 at intervals along the axial direction of the loading element 25. As in the example of Fig. 15, the loading element 25 includes two clips 252, and the two clips 252 clamp the lenses 241 between the two clips 252.

It can be understood that since the loading element 25 is used to fix and set a plurality of lenses 241, the required length of the loading element 25 is relatively large, and the loading element 25 can be a cylindrical, square cylindrical, or other structure with a cavity. In this way, the loading element 25 is cylindrical, and the loading element 25 can better set 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 Figure 15, the loading component 25 clamps multiple lenses 241 between two clips 252, which not only has a certain stability, but also can reduce the weight of the loading component 25, and can reduce the power required for the driving mechanism 27 to drive the loading component 25. The design difficulty of the loading component 25 is also relatively low, and the lenses 241 are also easier to set on the loading component 25.

Of course, the loading element 25 is not limited to the above-mentioned cylindrical shape and two clips 252. In other embodiments, the loading element 25 may include three, four or more clips 252 to form a more stable structure, or a simpler structure such as one clip 252; or various regular or irregular shapes such as a rectangular body, a circular body, etc. with a cavity to accommodate the lens 241. The specific selection can be made under the premise of ensuring the normal imaging and operation of the camera 10.

The first image sensor 26 may be a complementary metal oxide semiconductor (CMOS) 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, when the driving mechanism 27 is an electromagnetic driving mechanism, the driving mechanism 27 includes a magnet and a conductor, wherein the magnet is used to generate a magnetic field, and the conductor is used to drive 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 the Ampere force, thereby driving the loading element 25 to move.

When the driving mechanism 27 is a piezoelectric driving mechanism, based on the inverse piezoelectric effect of the piezoelectric ceramic material, a voltage can be applied to the driving mechanism 27 to generate mechanical stress in the driving mechanism 27. In other words, through the conversion between electrical energy and mechanical energy, the driving mechanism 27 is controlled to mechanically deform, thereby driving the loading element 25 to move.

When the drive mechanism 27 is a memory alloy drive mechanism, the drive mechanism 27 can be pre-memorized in a preset shape. When the loading element 25 needs to be driven to move, the drive mechanism 27 can be heated to a temperature corresponding to the preset shape to restore the drive mechanism 27 to the preset shape, thereby driving the loading element 25 to move.

Please refer to FIG. 16 . In the present embodiment, the first wide-angle camera 30 is a vertical camera. Of course, in other embodiments, the first wide-angle camera 30 may also be a periscope 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 to image light on the second image sensor 32 . The incident optical axis of the first wide-angle camera 30 coincides with the optical axis of the second lens assembly 31 .

In this embodiment, the first wide-angle camera 30 may be a fixed-focus lens module. Therefore, the second lens assembly 31 has fewer lenses 241 , so that the height of the first wide-angle camera 30 is lower, which is beneficial for 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 in detail herein.

The structure of the second wide-angle camera 40 is similar to that of the first wide-angle camera 30. For example, the second wide-angle camera 40 is also a vertical camera. Therefore, the features of the second wide-angle camera 40 refer to the features of the first wide-angle camera 40, which will not be repeated here.

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

f2＜f3＜f1;

1＜f3/f2≤5;

5＜f1/f2≤10;

Among them, f1 is the equivalent focal length of the periscope 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.

In this way, the periscope camera 20 adopts a periscope imaging module, so that the periscope camera 20 and the first wide-angle camera 30 can cooperate to obtain an optical zoom effect greater than 5 times. In addition, the first wide-angle camera 30 and the second wide-angle camera 40 can cooperate to obtain an optical zoom effect greater than 1 times and less than or equal to 5 times. In this way, the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 cooperate to enable the camera assembly 100 to achieve an optical zoom between 1-10 times, thereby improving the shooting effect of the camera assembly 100.

Generally, the industry is accustomed to converting the imaging angle of different-sized photosensitive elements into the lens focal length corresponding to the same imaging angle on a 135 film camera (the photosensitive surface of a 135 film camera is fixed and unchanged, with 35mm film specifications). This converted focal length is the equivalent focal length of the 135 film camera, i.e. the equivalent focal length. Since the size of the photosensitive element (CCD or CMOS) of a digital camera varies from camera to camera (such as 1/2.5 inch, 1/1.8 inch, etc.), the imaging angle of the lens of the same focal length on a digital camera with a photosensitive element of different sizes is also different. But for users, what really matters is the camera's shooting range (angle of view), that is, people are more concerned about the equivalent focal length rather than the actual focal length.

In one example, f3/f2 is 1.5, 2, 2.5, 3, 4 or 5. In other words, the first wide-angle camera 30 and the second wide-angle camera 40 can cooperate to achieve 1.5 times, 2 times, 2.5 times, 3 times, 4 times or 5 times optical zoom. Preferably, in one example, 1＜f3/f2≤3. f1/f2 can be a specific value of 6, 7, 8, 9 or 10. In other words, the periscope camera 20 and the first wide-angle camera 30 can cooperate to achieve 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 camera 20 is large, which also makes the size of the first image sensor larger, resulting in a larger size of the periscope camera 20, which is not conducive to the thin and light design of the electronic device 1000. Therefore, controlling the optical zoom ratio of the camera assembly 100 within 10 times can not only meet the user's photography needs, but also ensure the thin and light design of the electronic device 1000.

In one embodiment, the first wide-angle camera 30 is the main camera. In other words, in general, the first wide-angle camera 30 is turned on to take pictures. The periscope camera 20 and the second wide-angle camera 40 can be used as auxiliary cameras. When the user needs to zoom in on the image for shooting, the periscope camera 20 or the second wide-angle camera 40 is turned on.

In one example, f3/f2=2, f1/f2=10. At this time, the camera assembly 100 can achieve 1x, 2x or 10x optical zoom effects. When the user turns on the shooting function of the electronic device 1000, the first wide-angle camera 30 is turned on to obtain the pre-shot scene; when the user selects a 2x magnification effect in the pre-shot 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 shooting scene magnified 2x; when the user selects a 10x magnification effect in the pre-shot scene, the first wide-angle camera 30 is turned off, and the periscope camera 20 is turned on, so that the periscope camera 20 can obtain the shooting scene magnified 10x. In this way, it can be understood that since the image magnification of the pre-shot scene is obtained through optical zoom, the camera assembly 100 can obtain an image of the pre-shot scene with better quality.

In one embodiment, the combination of the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 of the camera assembly 100 is shown in Table 1 below:

Table I:

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

In another embodiment, the combination of the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 of the camera assembly 100 is shown in Table 2 below:

Table II:

In yet another embodiment, the combination of the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 of the camera assembly 100 is shown in Table 3 below:

Table 3:

It should be pointed out that the number of the second wide-angle cameras 40 can be multiple, as shown in Table 1, Table 2 and Table 3 above. Multiple second wide-angle cameras 40 enable the first wide-angle camera 30 and the second wide-angle camera 40 to cooperate to achieve more zoom multiples, which is beneficial to improving the shooting effect of the electronic device 1000.

In some embodiments, there are multiple periscope cameras 20, and the equivalent focal lengths of the multiple periscope cameras 20 are different. In other words, the number of imaging modules of the camera assembly 100 can be greater than 3. In this way, the camera assembly 100 can achieve multiple optical zoom multiples between 5-10 times.

In one example, the number of periscope cameras 20 is 3, namely periscope camera I, periscope camera II and periscope camera III, wherein the ratio of the equivalent focal length of periscope camera I to the equivalent focal length of the 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 the 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 the first wide-angle camera 30 is about 10. In other words, periscope camera I cooperates with the first wide-angle camera 30 to enable the camera assembly 100 to achieve 7 times optical zoom. Periscope camera II cooperates with the first wide-angle camera 30 to enable the camera assembly 100 to achieve 9 times optical zoom. Periscope camera III cooperates with the first wide-angle camera 30 to enable the camera assembly 100 to achieve 10 times optical zoom.

In one embodiment, the combination of the periscope camera 20, the first wide-angle camera 30 and the second wide-angle camera 40 of the camera assembly 100 is shown in Table 4 below:

Table 4:

In some embodiments, the resolution of the periscope camera 20 is the same as the resolution of the first wide-angle camera 30. Thus, at the same resolution, the periscope camera 20 and the first wide-angle camera 30 cooperate to achieve an optical zoom greater than 5 times, so that the image quality of the enlarged pre-shot scene is better.

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

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

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

Please refer to Figure 17, which shows a structural schematic diagram of an electronic device 1000 according to another embodiment of the present application. The example in Figure 17 is different from the example in Figure 1 in that in the example in Figure 17, the electronic device 1000 includes an extension module 130, and the extension module 130 is used to move between a first position housed in the housing 110 and a second position extended from the housing 110. The extension module 130 is provided with a flash 60. When the extension module 130 is in the second position, the flash 60 is located outside the housing 110.

That is to say, the flash 60 is separately arranged from the camera assembly 100. The extending module 130 can slide out of the housing 110 or rotate out of the housing 110. In the present application, the extending module 130 rotates out of the housing 110. The extending module 130 can also be provided with a front camera. When the extending module 130 is extended out of the housing 110, the electronic device 1000 can perform front-facing shooting.

It should be noted that the light emitting direction of the flash 60 is consistent with the framing direction of the periscope camera 60. In other words, the flash 60 is used to fill in the back environment of the electronic device 1000.
