[0037] 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 should not be understood as limiting the present application.

[0038] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0039] See also Figure 1 and Figure 2The camera 100 of the embodiment of the present application includes an image sensor 10 and a lens 20. The lens 20 is used to form an image on the image sensor 10. The lens 20 includes a plurality of lens groups 21. The plurality of lens groups 21 are arranged along the optical axis of the lens 20.

[0040] At least one lens group 21 is capable of moving relative to the image sensor 10 to switch the lens 20 between a first mode and a second mode, wherein the focus object distance of the lens 20 in the first mode is smaller than the focus object distance in the second mode; in the first mode, the focus object distance of the lens 20 is less than 10 mm.

[0041] The camera 100 of the present embodiment switches the lens 20 between a first mode and a second mode by moving the lens assembly 21 relative to the image sensor 10. The first mode corresponds to shooting in the micro mode of the camera 100, and the second mode corresponds to shooting in the macro mode of the camera 100. Therefore, switching the lens 20 mode allows the same camera 100 to switch between the micro shooting mode and the macro shooting mode, increasing the diversity of the camera 100's usage scenarios.

[0042] Specifically, the image sensor 10 may be a photosensitive element disposed in the camera 100 , and the image sensor 10 may convert an optical signal into an electrical signal. The image sensor 10 may be disposed inside the camera 100 and below the lens 20 .

[0043] The lens 20 may include multiple lens groups 21, which are arranged along the optical axis of the lens 20. The optical axis may be the axis of a light beam passing through the center of the lens 20. The multiple lens groups 21 may be independent of each other, and at least one of the multiple lens groups 21 may be movable relative to the image sensor 10 along the optical axis. This movement of the lens group 21 may change the focus distance of the lens 20, thereby switching the lens 20 between the first mode and the second mode.

[0044] The first mode can be a microscopic distance where the distance D1 between the lens 20 and the object 2000 plane is less than 10 mm. For example, D1 can be a microscopic distance of 5 mm. In this case, the focus object distance achieved by the lens 20 is also less than 10 mm, so that the object 2000 plane at the microscopic distance from the lens 20 is clearly imaged on the image sensor 10 through the lens 20.

[0045] Furthermore, the second mode can be a distance D2 between the lens 20 and the plane of the object 2000 greater than 10 mm. For example, D2 can be a macro distance of 30 mm. In this case, the focus object distance achieved by the lens 20 is also greater than 10 mm, so that the object 2000 at the macro distance from the lens 20 can be clearly imaged on the image sensor 10 through the lens 20.

[0046] See also Figure 1 and Figure 2 In some embodiments, each lens group 21 includes at least one lens 22 .

[0047] In this way, at least one lens 22 is combined in the plurality of lens groups 21 so that the plurality of lens groups 21 can achieve the transformation of the focus object distance of the lens 20 by using the plurality of lenses 22 .

[0048] Specifically, the lens 22 may be a convex lens or a concave lens. One or more lenses 22 may be packaged together in a lens group 21, and the number of lenses 22 in different lens groups 21 may be different.

[0049] In some embodiments, the total number of lenses 22 of the lens 20 is 4 or 5.

[0050] In this way, the total number of lenses 22 of the lens 20 is 4 or 5, which can ensure that there are enough lenses 22 in the multiple lens groups 21 to achieve the focus object distance switching of the lens 20.

[0051] Specifically, the total number of lenses 22 in the lens system 20 may be the sum of the number of lenses 22 in the multiple lens groups 21 in the lens system 20. Each lens group 21 includes at least one lens 22. When the total number of lenses 22 is four or five, the lenses 22 in the multiple lens groups 21 may be combined in different ways to achieve a total of four or five lenses 22 in the multiple lens groups 21.

[0052] For example, if the lens system 20 includes two lens groups 21, one of the lens groups 21 may include two lenses 22, and the other lens group 21 may also include two lenses 22. Therefore, the total number of lenses 22 in the lens system 20 may be four. Similarly, the two lens groups 21 may be combined in a "1+3" or "3+1" pattern.

[0053] It can be understood that the number of numbers within the quotation marks in the combination "1+3" represents the number of lens groups, and the sum of these numbers represents the total number of lenses. Therefore, two numbers within the quotation marks "1+3" can indicate two lens groups, and a sum of 4 can indicate a total number of lenses of four. The number "1" can indicate that one of the two lens groups 21 has one lens 22, while the number "3" can indicate that the other of the two lens groups 21 has three lenses 22. Other combinations can be deduced in the same way.

[0054] Furthermore, if the total number of lenses 22 in the lens system 20 is five, the two lens groups 21 can be combined in a "2+3" or "3+2" pattern. It should be understood that the number of lens groups 21 and the total number of lenses 22 can also be combined in various ways, and can be combined with the different numbers of lenses 22 in a single lens group 21. For example, if the total number of lenses 22 in three lens groups 21 is four, the combination pattern is "1+1+2," or if the total number of lenses 22 in four lens groups 21 is five, the combination pattern is "2+1+1+1," and so on. This is not a specific limitation.

[0055] See also Figure 1 、 Figure 2 and Figure 5 In some embodiments, the lens group 21 includes a first lens group 211 and a second lens group 212 . The first lens group 211 is located between the image sensor 10 and the second lens group 212 . The first lens group 211 can move relative to the image sensor 10 .

[0056] In this way, the focus object distance of the lens group 21 can be changed by moving the first lens group 211 of the two lens groups 21 , so that the lens 20 is switched to the first mode or the second mode.

[0057] Specifically, the second lens group 212 and the first lens group 211 can be arranged in an upper and lower sequence along the optical axis of the lens group 21, with the second lens group 212 positioned at the top. Relative to the first lens group 211, the second lens group 212 can be positioned closer to the plane of the object 2000 and further away from the image sensor 10. A distance is provided between the second lens group 212 and the image sensor 10, and the first lens group 211 can be positioned between the second lens group 212 and the image sensor 10. The relative distance between the second lens group 212 and the image sensor 10 can remain constant, and the first lens group 211 can be driven by a drive device 50, such as a motor, to move between the second lens group 212 and the image sensor 10. The first lens group 211 can move toward or away from the image sensor 10, thereby switching the lens 20 between the first mode and the second mode.

[0058] See also Figure 3 、 Figure 4 and Figure 6 In some embodiments, the lens group 21 includes a first lens group 211, a second lens group 212 and a third lens group 213, the first lens group 211 is located between the second lens group 212 and the third lens group 213, and the third lens group 213 is arranged relative to the second lens group 212 and close to the image sensor 10.

[0059] In this way, the focus object distance of the lens group 21 can be changed by moving the first lens group 211 among the three lens groups 21 , so that the lens 20 is switched to the first mode or the second mode.

[0060] Specifically, the second lens group 212, the first lens group 211, and the third lens group 213 can be arranged in a vertical order along the optical axis of the lens group 21. The second lens group 212 can be arranged at the top, closer to the plane of the object 2000 and farther from the image sensor 10 relative to the first lens group 211. The third lens group 213 can be closer to the image sensor 10 and farther from the plane of the object 2000 relative to the first lens group 211. A distance is spaced between the second lens group 212 and the third lens group 213. The first lens group 211 can be arranged between the second lens group 212 and the third lens group 213. The relative distance between the second lens group 212 and the third lens group 213 can remain unchanged, and the relative distance between the third lens group 213 and the image sensor 10 can remain unchanged.

[0061] The first lens group 211 can be driven by a motor or other driving device 50 to move between the second lens group 212 and the third lens group 213. The movement direction can be toward or away from the image sensor 10, thereby switching the lens 20 to the first mode or the second mode.

[0062] See also Figures 1-4 In some embodiments, the first lens group 211 has a first position and a second position, and the first lens group 211 is closer to the second lens group 212 when in the first position;

[0063] When the first lens group 211 is in the first position, the lens 20 is in the first mode, and when the first lens group 211 is in the second position, the lens 20 is in the second mode; or

[0064] When the first lens group 211 is located at the first position, the lens 20 is in the second mode; when the first lens group 211 is located at the second position, the lens 20 is in the first mode.

[0065] In this way, the first lens group 211 in the first position or the second position can correspond to the first mode or the second mode of the lens 20 , so that the first lens group 211 can have a clear corresponding mode of the lens 20 when it moves to the corresponding position.

[0066] Specifically, the first lens group 211 is in the first position (eg Figure 1 or Figure 3 ) compared to the second position (as shown Figure 2 or Figure 4211 ). During the switching process between the first mode and the second mode of the lens 20, the mode of the lens 20 can be switched by placing the first lens group 211 in different positions. The first position of the first lens group 211 can be a position within the range of movement where the first lens group 211 is closer to the second lens group 212. In this case, the focus object distance of the entire lens group 211 can be a macro distance of less than 10 mm, and the lens 20 can be in the first mode. The second position of the first lens group 211 can be a position within the range of movement where the first lens group 211 is closer to the image sensor 10. In this case, the focus object distance of the entire lens group 211 can be a macro distance of greater than 10 mm, and the lens 20 can be in the second mode.

[0067] Because the focus-object distances of lens group 21 vary in different positions depending on the focal length distribution design of lens group 21, when first lens group 211 is in the first position, the focus-object distance of the entire lens group 21 can be a macro distance greater than 10 mm, and lens 20 can be in the second mode. When first lens group 211 is in the second position, the focus-object distance of the entire lens group 21 can be a micro distance less than 10 mm, and lens 20 can be in the first mode.

[0068] It should be understood that when the first lens group 211 switches between the first position and the second position, the focus-object distance of the entire lens group 21 may change in stages or continuously. For example, when the first lens group 211 switches between the first position and the second position, the focus-object distance of the lens 20 may switch only from 30 mm to 5 mm, representing an intermittent change. Alternatively, when the first lens group 211 switches between the first position and the second position, the focus-object distance of the lens 20 may switch gradually from 30 mm to 5 mm, representing a continuous change.

[0069] See also Figure 5 and Figure 6 In some embodiments, the camera 100 includes a detection element 40 disposed on the first lens group 211 , and the detection element 40 is used to detect the position of the first lens group 211 .

[0070] In this way, the detection element 40 disposed on the first lens group 211 can detect the position of the first lens group 211, so that the camera 100 can determine whether the lens 20 is in the first mode or the second mode according to the detected position.

[0071] Specifically, the modular components of the camera 100, such as the first lens group 211, the second lens group 212, and the image sensor 10, are interconnected and fixed, and the connection method can be bonding with glue. The components of the camera 100 can be interconnected from top to bottom. The upper layer can be the second lens group 212. Connected to the second lens group 212 and located below the second lens group 212 can be the first lens group 211 and a driving device 50, such as a motor, that drives the first lens group 211 to move toward or away from the second lens group 212. The driving device 50 can also drive the first lens group 211 to move horizontally to achieve the anti-shake function of the lens 20. At the bottom can be the circuit board 70 and the image sensor 10. The image sensor 10 can be arranged on the side of the circuit board 70 facing the first lens group 211. An infrared filter 60 can also be arranged between the image sensor 10 and the first lens group 211.

[0072] The detection element 40 can be disposed on the first lens assembly 211 and can be a Hall effect device, a magnet, or a coil. The detection element 40 can be disposed in pairs on the first lens assembly 211 and the drive device 50. For example, a Hall effect device can be disposed on one side of the first lens assembly 211, while a magnet or coil can be disposed on the corresponding drive device 50. The detection element 40 can then detect the position of the first lens assembly 211 by performing magnetic or photoelectric detection with the detection element 40 paired with the drive device 50 that drives the first lens assembly 211.

[0073] For example, when a Hall element is used as the detection element 40 on the first lens group 211 and a motor is used as the driving device 50 to drive the first lens group 211, another detection element 40 can be correspondingly provided on the motor, for example, a magnet paired with the Hall element, and then the position of the first lens group 211 can be determined by the magnetic field induced by the Hall element.

[0074] See also Figure 5 and Figure 6 In some embodiments, the moving distance S of the first lens group 211 ranges from 300 μm to 1500 μm.

[0075] In this way, the moving distance S of the first lens group 211 ranges from 300 μm to 1500 μm, which can better meet the change of the focus object distance of the lens 20 between the first mode and the second mode.

[0076] Specifically, the movement distance S range of the first lens group 211 may be the distance between the upper surface of the first lens group 211 when the first lens group 211 is in the first position and the upper surface of the first lens group 211 when the first lens group 211 is in the second position. The value of the movement distance S range may depend on the focal length of the lens group 21, and the value of S may be approximately 300 μm-1500 μm.

[0077] See also Figure 2 and Figure 4 In some embodiments, in the second mode, the focus object distance of the lens 20 is less than or equal to 30 mm.

[0078] In this way, the lens 20 in the second mode can achieve the microscopic shooting distance of the camera 100.

[0079] Specifically, in the second mode, the focus distance of the lens 20 is greater than 10 mm in the first mode and less than or equal to 30 mm, corresponding to the shooting state of the camera 100 at a macro distance from the object 2000. Therefore, the lens 20 can achieve focus at a macro distance, and a clear image can be obtained on the image sensor 10 when the camera 100 is at a macro distance from the object 2000.

[0080] See also Figure 7 and Figure 8 In some embodiments, the image sensor 10 includes a pixel array 11, a light-transmitting flexible film layer 12, and a driving device 13. The flexible film layer 12 is stacked with the pixel array 11; the driving device 13 is disposed on the flexible film layer 12, and the driving device 13 can change the curvature of the flexible film layer 12 to correct the field curvature of the lens 20.

[0081] In this way, the image sensor 10 has a flexible membrane layer 12 with variable curvature. The image sensor 10 can use the driving device 13 to change the curvature of the flexible membrane layer 12, thereby changing the curvature of the image sensor 10; the change in the curvature of the image sensor 10 can correct the field curvature generated by the lens 20 during microscopic photography, so that the image is clear.

[0082] Specifically, the image sensor 10 may be a photosensitive element used in electronic devices with camera functions, such as mobile phones and digital cameras. The image sensor 10 converts light signals into electrical signals. The pixel array 11 may be the region of the image sensor 10 that senses light and performs photoelectric conversion. The pixel array 11 may be stacked on top of a flexible film layer 12, with the pixel array 11 located below the flexible film layer 12. The flexible film layer 12 may be a flexible thin film layer made of a material such as glass, and may be approximately 5 microns thick.

[0083] The driving device 13 may be a device that drives the flexible film layer 12 to bend by deforming itself, thereby changing the curvature of the flexible film layer 12. The driving device 13 may be disposed on the flexible film layer 12, for example, on a surface of the flexible film layer 12 facing away from the pixel array 11.

[0084] Available through Figure 9To further illustrate, when the distance between lens 20 and the plane of object 2000 is a microscopic distance (for example, at an object distance of 5 mm), light 30 emitted by object 2000 is focused by lens 20 onto image sensor 10. Due to the field curvature produced by lens 20, some light 30 passes through lens 20 and is focused on the rear side of image sensor 10, where flexible membrane 12 is unbent, resulting in a blurred image. In this case, driver 13 can bend flexible membrane 12, thereby changing the curvature of image sensor 10. This change in curvature allows all light 30 emitted by object 2000 to be focused on image sensor 10, resolving the image blur issue and providing a clearer image.

[0085] See also Figure 7 and Figure 8 In some embodiments, the driving device 13 includes a piezoelectric device 131. When a voltage is applied to the piezoelectric device 131, the piezoelectric device 131 deforms to drive the flexible membrane layer 12 to deform.

[0086] In this way, applying voltage can quickly control the deformation of the piezoelectric device 131, increase the deformation speed of the flexible membrane layer 12, and further increase the correction speed of the field curvature generated by the image sensor 10 on the lens 20.

[0087] Specifically, the piezoelectric device 131 may be a piezoelectric actuator, for example, the piezoelectric device 131 may be a piezoelectric film, and realizes its own deformation through thin film piezoelectric technology. For example, when a voltage of 0V is applied to the piezoelectric device 131, the piezoelectric device 131 itself does not change, and the flexible membrane layer 12 does not deform (e.g., Figure 7 When a voltage of 40V is applied to the piezoelectric device 131, the piezoelectric device 131 itself is deformed. When the piezoelectric device 131 is deformed, the flexible film layer 12 is deformed, and the flexible film layer 12 is deformed. The deformation of the flexible film layer 12 can be such that the middle area of ​​the flexible film layer 12 is convex compared to the undeformed state (as shown in FIG. Figure 8 shown).

[0088] See also Figure 7 and Figure 8 In some embodiments, the piezoelectric device 131 is disposed at an edge of the flexible membrane layer 12 .

[0089] In this way, the piezoelectric device 131 disposed at the edge of the flexible film layer 12 will not block the light transmittance in the middle of the flexible film layer 12 , so that the amount of light passing through the flexible film layer 12 and contacting the pixel array 11 is normal.

[0090] Specifically, the piezoelectric device 131 may be disposed on an outer edge side of the flexible membrane layer 12 , and the piezoelectric device 131 may be connected to the flexible membrane layer 12 around an outer edge position of the flexible membrane layer 12 .

[0091] See also Figure 10 In some embodiments, a microlens array 121 is formed on the flexible film layer 12 , and the microlens array 121 is used to focus light onto the pixel array 11 .

[0092] In this way, the microlens array 121 is disposed on the flexible film layer 12 to focus light toward the pixel array 11 , thereby increasing the fill factor of the pixel array 11 and improving the imaging effect of the image sensor 10 .

[0093] Specifically, the microlens array 121 includes a plurality of sub-lenses, which may be arranged in an array, and the diameters of the sub-lenses may be in the nanometer or millimeter order. The microlens array 121 may achieve parallel refractive focusing through the sub-lenses.

[0094] See also Figure 10 In some embodiments, the microlens array 121 is formed on the surface of the flexible film layer 12 facing away from the pixel array 11. In this way, the arrangement of the microlens array 121 can direct the focused light path toward the pixel array 11.

[0095] Specifically, the microlens array 121 may be disposed on a side of the flexible film layer 12 away from the pixel array 11 , and the convex surfaces of the sub-lenses on the microlens array 121 may protrude upward away from the flexible film layer 12 , so that the microlens array 121 has a light-collecting effect.

[0096] See also Figure 7 and Figure 8 In some embodiments, the image sensor 10 further includes a support layer 14 and a flexible connector 15 . The support layer 14 is disposed on the pixel array 11 . The flexible connector 15 connects the flexible film layer 12 and the support layer 14 . The flexible connector 15 deforms as the flexible film layer 12 deforms.

[0097] In this way, the support layer 14 can support the flexible connector 15 , and the flexible connector 15 can deform accordingly with the deformation of the flexible film layer 12 to achieve a corresponding change in the focus position of the light, thereby enabling the image sensor 10 to have an automatic focusing capability.

[0098] Specifically, support layer 14 can be disposed above pixel array 11. Support layer 14 can be a supporting structural layer made of glass. Flexible connector 15 can have one end connected to support layer 14, and its end, facing away from support layer 14, can be connected to flexible film layer 12. Flexible connector 15 can be a polymer formed from a high molecular structure and can deform in response to the deformation of flexible film layer 12.

[0099] See also Figure 11 and Figure 12In some embodiments, the support layer 14 is formed with a filter array 141 , and the filter array 141 includes a red filter 1411 , a green filter 1412 , and a blue filter 1413 .

[0100] Thus, the filter array 141 formed on the support layer 14 can filter the color of the light entering the pixel array 11. Since the pixel array 11 cannot distinguish the color of light, the filter array 141 can help the pixel array 11 distinguish the color of light.

[0101] Specifically, the filter array 141 can be understood as an array that filters the wavelengths of light of different colors. The filter array 141 can filter the light entering the pixel array 11 in different channels. It can be understood that the filter array 141 is equivalent to modulating the incident signal, and the modulation mode usually adopted is the Bayer array. The filter array 141 may include a red filter 1411, a green filter 1412, and a blue filter 1413. Figure 11 As shown, when the filter array 141 adopts a Bayer array, it is composed of three channels: R, G, and B. R can represent a red filter 1411, G can represent a green filter 1412, and B can represent a blue filter 1413. The densities of the three channels R, G, and B can be 1 / 4, 1 / 2, and 1 / 4, respectively. After being modulated by the filter array 141, light can be incident on the pixel array 11 for photoelectric conversion and analog-to-digital conversion.

[0102] See also Figure 13 and Figure 14 The camera 100 of the embodiment of the present application includes the image sensor 10 and the lens 20 of the above embodiment, and the lens 20 is used to form an image on the image sensor 10.

[0103] The camera 100 of the embodiment of the present application can realize clear shooting of the object 2000 at a micro distance by imaging on the image sensor 10 through the lens 20. The image sensor 10 can correct the field curvature generated by the lens 20 when the distance between the lens 20 and the object is at a micro distance, so that the image captured by the camera 100 is clear.

[0104] Specifically, the camera 100 may be a camera 100 with multiple shooting functions such as macro and micro. The lens 20 may be an optical element composed of a glass lens. The lens 20 may be disposed above the image sensor 10 and may capture the image of the scene to be captured by the camera 100 and transmit it to the image sensor 10 for imaging.

[0105] See also Figure 13 and Figure 14 In some embodiments, the lens 20 can be moved relative to the image sensor 10 along the optical axis of the lens 20 to change the shooting mode of the camera 100.

[0106] In this way, the camera 100 can be adjusted to different shooting modes at different object distances by moving the lens 20 relative to the image sensor 10. Therefore, the camera 100 can improve the shooting effects in different modes after adjustment.

[0107] Specifically, the lens 20 is disposed above the image sensor 10 and may be directly opposite the image sensor 10. The lens 20 may be connected to a power device such as a motor, which may be used to drive the lens 20 to move along the optical axis. The optical axis may be the central axis direction of the lens 20 receiving light.

[0108] For example, Figure 13 As shown, the distance between the object 2000 to the upper surface of the lens 20 is L1, and L1 can be a macro distance. For example, when the distance L1 between the lens 20 and the object 2000 is 30 mm, it can be considered a macro distance. Figure 14 As shown, when the camera 100 needs to switch the shooting mode to the micro mode or the distance L2 between the object 2000 and the upper surface of the lens 20 is less than the macro distance L1, for example, when the distance L2 between the lens 20 and the object 2000 is at a macro distance of 5 mm, the lens 20 can be driven by the motor to move relative to the image sensor 10 along the optical axis in a direction away from the image sensor 10. For example, the distance moved by the lens 20 can be 840 microns. At this time, the outer field curvature of the lens 20 is relatively large, and the peripheral field curvature can be close to 30 μm.

[0109] Please combine Figure 9 , the image sensor 10 will change its curvature accordingly so that the image captured by the lens 20 forms a clear image on the image sensor 10 .

[0112] Specifically, electronic device 1000 may be a terminal device with a camera function. For example, electronic device 1000 may include a smartphone, tablet, computer, digital camera, or other terminal device with a camera function. Camera 100 may be provided on electronic device 1000, such as a rear camera of a mobile phone, a camera of a digital camera, etc. Camera 100 is used to simultaneously implement microscopic and macro photography functions of electronic device 1000.
