Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

Referring to fig. 1, an electronic device 100 according to an embodiment of the present disclosure includes a camera assembly 10 and a housing 20.

Specifically, the electronic apparatus 100 may be any of various types of computer system devices that are mobile or portable and perform wireless communication. For example, the electronic apparatus 100 may be a mobile phone, a portable game device, a laptop computer, a PDA (personal digital assistant), a PAD (PAD), a portable internet device, a wearable device, a vehicle-mounted terminal, a navigator, a music player, a data storage device, and the like. The specific form of the electronic device 100 is not limited herein. Next, the electronic device 100 will be described as a mobile phone.

The housing 20 is an external component of the electronic device 100, and functions to protect internal components of the electronic device 100. The housing 20 may be a rear cover of the electronic device 100, which covers components of the electronic device 100 such as a battery. In the present embodiment, the camera assembly 10 is disposed at the rear, or the camera assembly 10 is disposed at the rear of the electronic device 100 so that the electronic device 100 can perform rear-view imaging. In the example of fig. 1, the camera assembly 10 is disposed at an upper-middle position of the housing 20. Of course, it is understood that the camera assembly 10 may be disposed at other positions such as an upper left or upper right position of the housing 20. The position where the camera head assembly 10 is provided in the housing 20 is not limited to the example of the present application.

Referring to fig. 2 and 3, the camera assembly 10 includes a bracket 11, a camera 12, and a polarization element 13.

The bracket 11 includes a top wall 111, a side wall 112, an accommodating space 113 and a bottom wall 114. The top wall 111 is provided with an opening 1111, and the polarization member 13 is disposed at the opening 1111. The top wall 111, the side wall 112 and the bottom wall 114 are connected to form an accommodating space 113. The camera 12 is connected to the bracket 11 and disposed in the accommodating space 113.

So, make camera 12 and polarization component 13 keep relative position relation through support 11, avoided polarization component 13 and camera 12 dislocation and lead to not penetrating into camera 12 through the light that polarization component 13 filters, and make the formation of image effect relatively poor, be favorable to improving camera 12's formation of image effect. Moreover, the bracket 11 can directly integrate the camera 12 and the polarization element 13, and does not need to separately set or debug the installation position, thereby facilitating the assembly of the electronic device 100.

In particular, in some embodiments, polarizing element 13 may be disposed in opening 1111, i.e., polarizing element 13 occupies some or all of the space of opening 1111 in the direction of the plane of top wall 111. For example, referring to fig. 4, the polarizing element 13 occupies the entire space of the opening 1111 in the direction of the plane of the top wall 111.

In other embodiments, the polarization element 13 may be disposed outside the opening 1111 and cover the opening 1111 in a direction perpendicular to the plane of the top wall 111.

For example, referring to fig. 5, the polarization element 13 is disposed on the top wall 111 of the opening 1111 and covers the opening 1111 in a direction perpendicular to the plane of the top wall 111. In the example of fig. 5, a limiting ring 1110 may be further formed on the top wall 111, the polarizing element 13 occupies the entire space of the limiting ring 1110 in the direction of the plane of the limiting ring 1110, and the polarizing element 13 may rotate in the limiting ring 1110. Therefore, the position of the polarization element 13 is limited by the limiting ring 1110, and the polarization element 13 is prevented from moving to a position where the opening 1111 cannot be covered, so that light rays which are not filtered by the polarization element 13 enter the camera 12, and the image quality is guaranteed.

The specific manner in which the polarizing element 13 is disposed in the opening 1111 is not limited herein. For convenience of explanation, the following description will be given taking an example in which the polarizing element 13 is disposed outside the opening 1111 and covers the opening 1111 in a direction perpendicular to the plane of the top wall 111.

In the present embodiment, the opening 1111 has a circular shape. It is understood that in other embodiments, the opening 1111 may be rectangular, square, oval, triangular, or other irregular shape. The specific shape of the opening 1111 is not limited herein.

Alternatively, the holder 11 may be made of plastic. For example, the holder 11 is made of Acrylonitrile Butadiene Styrene (ABS) plastic. Therefore, the support 11 can resist fatigue and stress cracking, and the reliability of the support 11 is improved. Moreover, the bracket 11 can be easily processed and formed, which is beneficial to improving the production efficiency of the bracket 11.

In the example of fig. 2 and 3, the number of sidewalls 112 is four. It is understood that in other embodiments, the number of sidewalls 112 may be 1, 2, 3, 5, or other numbers. The specific number of sidewalls 112 is not limited herein.

In the example of fig. 2 and 3, the sidewall 112 is not formed with an aperture. Thus, external moisture and dust are difficult to enter the interior of the camera head assembly 10 through the side walls 112, which may improve the reliability of the camera head assembly 10.

It is understood that in other examples, at least one of the four sidewalls 112 may be formed with an aperture 1121. For example, one sidewall 112 of the four sidewalls 112 is formed with an opening 1121; two side walls 112 of the four side walls 112 are formed with openings 1121; three side walls 112 of the four side walls 112 are formed with openings 1121; openings 1121 are formed in each of the four side walls 112, as shown in fig. 6 and 7.

In the example of fig. 6 and 7, four sidewalls 112 each form an aperture 1121. Thus, the camera 12 can be inserted into and fixed in the accommodating space 113 through the opening 1121, which is also convenient for adjusting the position of the camera 12 when the camera 12 is inserted. It is understood that the number of the openings 1121 formed in each sidewall 112 may also be 2, 3, 4 or other numbers, and is not limited herein.

In the present embodiment, the bottom wall 114 is opposed to the top wall 111. The bottom wall 114 includes a first portion 1141 and a second portion 1142, the first portion 1141, the top wall 111 and the side wall 112 are connected to form the accommodating space 113, the second portion 1142 is formed by extending the first portion 1141 in a direction opposite to the direction of the accommodating space 113, the first portion 1141 and the second portion 1142 may be integrally formed, and may also be formed by splicing in a bonding manner, a fastening manner, etc., and are not limited herein.

Referring to fig. 3 and 7, the camera 12 is disposed in the accommodating space 113. In the present embodiment, the camera 12 is provided in the first portion 1141 of the bottom wall 114. Thus, the bottom area of the camera 12 is large, and the contact area with the bottom wall 114 is large, so that the camera 12 is more stably arranged in the accommodating space 113, which is beneficial to improving the shooting effect of the camera 12. Further, the bottom of the camera head 12 meets the top of the first portion 1141 of the bottom wall 114. Further, the camera head 12 and the first portion 1141 may be connected by an adhesive layer, such as a double-sided adhesive layer.

Further, the first portion 1141 may be formed with a groove corresponding to the opening 1111, and the camera 12 may be disposed in the groove. Thus, the camera 12 can be positioned by the groove, thereby improving the installation efficiency. The bottom wall may also be formed with a positioning member such as a projection, and the specific form of the positioning member is not limited herein. The camera head 12 and the bottom wall may also be connected by means of snaps, screws, etc. The particular manner of connection of the camera head 12 to the bottom wall is not limited herein.

It is understood that in other embodiments, the camera head 12 may be connected to the side wall 112 or the top wall 111 of the stand 11. In this manner, camera head assembly 10 may not include bottom wall 114, which may reduce the weight of camera head assembly 10 while ensuring proper operation of camera head 12. The specific connection manner of the camera 12 and the bracket 11 is not limited herein.

In this embodiment mode, the polarizing element 13 is provided in the opening 1111. Thus, the polarizing element 13 is not blocked by the top wall 111, and the incident light of the camera module 10 can be ensured to be incident on the polarizing element 13.

The polarization element 13 can rotate relative to the bracket 11 to filter out predetermined polarized light in the incident light of the camera assembly 10, so that the camera 12 can image with the filtered incident light. Therefore, the adverse effect of the preset polarized light on the image in the shooting process can be reduced or even eliminated, and the image transparency degree and the dynamic range are favorably improved, so that the image quality is improved.

It is understood that the electronic device of the related art generally takes an image through an imaging module. In order to obtain a higher Dynamic Range and improve the details of the dark portion, an image obtained by the imaging module is usually optimized by an algorithm using a High-Dynamic Range (HDR) mode. In other words, in the shooting process, three types of photos of an underexposed image, a normal image and an overexposed image are combined into one photo, a dark area of the normal image is combined by taking a corresponding area of the overexposed image, and a bright area of the normal image is combined by taking a corresponding area of the underexposed image. However, the HDR mode has a limited improvement in the photographing effect, resulting in poor image quality.

For example, in the case of a reflected light scene such as water ripples and glass reflected light, it is difficult in the related art to clearly image a subject through a large reflection light surface.

For another example, for high-contrast scenes such as sky, mountains, and rivers, the synthesis range of the HDR algorithm of the related art is limited, and normal exposure of a partial region, overexposure of a partial region, or underexposure of a partial region still occur.

For another example, when the related art uses the optical drawing function in the daytime, a large-area white overexposure image is easily formed, an accurate scene cannot be shot, and the impression is poor.

Because the angles of the polarized light caused by different objects are different, in the present embodiment, the polarization element 13 rotates relative to the bracket 11, so that the predetermined polarized light in the incident light of the camera assembly 10 can be filtered, thereby reducing or even eliminating the adverse effect of the predetermined polarized light on the image in the shooting process, and being beneficial to improving the transparency and dynamic range of the image, thereby improving the image quality.

For example, the camera module 10 of the present embodiment can clearly and transparently photograph a subject without being affected by reflected light when photographing a strong reflection scene such as a water surface, a glass, or the like.

For another example, when the camera assembly 10 of the present embodiment is used to shoot high-contrast scenes such as blue sky, white clouds, mountains, and vegetation, the effect of reflecting air such as haze and dust can be reduced, and meanwhile, the contrast is reduced by reducing the amount of light passing through, so that the real color is restored, the object to be shot is more transparent, and the definition and color saturation of the scene are increased.

For example, in the camera module 10 of the present embodiment, since the amount of light transmitted per unit time can be reduced by the polarizer 13, it is possible to achieve a long exposure effect during the day by using a slow shutter, and to photograph a stream of people, a stream of silk threads, clouds, and the like.

The polarizing element 13 is capable of rotating clockwise or counterclockwise about the central axis 130 of the polarizing element 13. The specific rotation direction of the polarizing element 13 is not limited herein.

In the present embodiment, the polarization element 13 may be controlled to rotate from the initial position. Therefore, through the setting of the initial position, the reference position is arranged in each rotation, the determination of the rotation angle is facilitated, and the accuracy of the target position can be ensured.

Referring to FIG. 8, the polarizer 13 rotates clockwise about the central axis 130 from the initial position A to the target position B after rotating by a certain rotation angle α, such that the indication line 1301 rotates from the initial position A to the target position B. referring to FIG. 9, in another example, the polarizer 13 rotates counterclockwise about the central axis 130 from the initial position A to the target position B after rotating by a certain rotation angle β, such that the indication line 1301 rotates from the initial position A to the target position B.

Note that the indication lines 1301 are shown in fig. 8 and 9 to more clearly show the rotation of the polarization member 13. The indicator line 1301 may not be present in the polarizing element 13. The indicator line 1301 may be related to the structure of the polarizing element 13. For example, the edge of the polarization element 13 may be formed with a protrusion, and a line connecting the protrusion and the center of the polarization element 13 is used as the indication line 1301.

Further, after each shooting is finished, the polarization element 13 may be reset to the initial position to wait for the next rotation. Therefore, the next rotation can be directly started from the initial position, the initial position does not need to be reset first, and the response time can be shortened.

Referring to fig. 10, the polarizer 13 rotates clockwise around the central axis 130 from the initial position a to the target position B after rotating a certain rotation angle α, and rotates clockwise β degrees from the target position B to the initial position a after finishing shooting, and the sum of α and β is 360 °.

In other embodiments, the polarization element 13 may be reset to the initial position before the polarization element 13 is rotated according to the determined rotation angle.

Referring to fig. 11, the current position C of the polarizer 13 is not the initial position a, and the polarizer 13 may be rotated clockwise from the current position C to the initial position a around the central axis 130, then rotated clockwise from the initial position a around the central axis 130, rotated by a certain rotation angle α, then rotated to the target position B, and then photographed.

In the present embodiment, the polarizing element 13 has a circular shape. In this manner, the shape of the polarization element 13 is adapted to the shape of the opening 1111, so that the rotation of the polarization element 13 in the opening 1111 is smoother.

It is understood that in other embodiments, the polarizing element 13 may be rectangular, square, oval, triangular, or other irregular shape. The specific shape of the polarizing element 13 is not limited herein.

In the present embodiment, the Polarizing element 13 is a Circular-Polarizing filter (CPL). Thus, after the predetermined polarized light is filtered by the circular polarizer, the light incident to the camera 12 is circularly polarized light, so that the image sensor of the camera 12 can recognize the light as natural light without exposure compensation, thereby avoiding overexposure of the image caused by the exposure compensation.

Referring to fig. 12, in particular, the circular polarizer may include a linear polarizer 131(Polarizing Filters, PL) and a quarter-wave plate 132. In this manner, filtering is performed by the linear polarizer 131, and light is converted into circularly polarized light by the quarter wave plate 132, so that the image sensor of the camera 12 recognizes light as natural light without exposure compensation, so as to avoid overexposure of an image caused by exposure compensation.

Referring to fig. 13 and 14, in the present embodiment, the camera assembly 10 further includes a driving device 14. The driving device 14 is provided in the second portion 1142. The driving device 14 is used for driving the polarization element 13 to rotate relative to the bracket 11.

Therefore, the user does not need to manually rotate the polarization element 13, the rotation precision can be ensured, the operation of the user is simpler, and the shooting effect and the user experience are favorably improved.

Specifically, the bottom of the drive device 14 meets the top of the second portion 1142. Further, the driving device 14 and the second portion 1142 may be connected by an adhesive layer, such as a double-sided adhesive layer. The driving device 14 and the second portion 1142 can be connected by means of a snap, a screw, etc. The specific connection between the driving device 14 and the second portion 1142 is not limited herein.

It will be appreciated that in other embodiments, the drive means 14 may be omitted and the user may manually rotate the polarising element 13. Thus, the operation feeling and the taste feeling of the user can be improved. The specific manner of driving the polarization element 13 to rotate is not limited herein.

In the present embodiment, the driving device 14 includes a driving member 141, a transmission member 142, and a connecting member 143.

The bottom of the driving member 141 meets the top of the second portion 1142. For example by means of glue, snaps, screws, etc. In this way, the connection of the driver 141 to the bracket 11 is achieved.

The drive 141 may comprise a synchronous motor. The synchronous motor has high operation stability and large overload capacity, can drive the polarizing element 13 more stably and accurately, and is favorable for ensuring the driving effect. The drive 141 may also comprise an asynchronous motor. The specific form of the driver 141 is not limited herein.

The transmission member 142 connects the driving member 141 and the polarization member 13, and the driving member 141 is used for driving the transmission member 142 to move, so as to rotate the polarization member 13 relative to the bracket 11. Thus, the rotation of the polarization element 13 is simply and conveniently realized by the driving member 141 and the transmission member 142.

Specifically, the driving member 141 and the polarization member 13 may be connected by a transmission member 142 such as a gear, a rack, a link, or the like. The specific form and the specific connection manner of the transmission member 142 are not limited herein.

In this embodiment, the transmission member 142 includes a driving gear 1421 and a driven gear 1422 engaged with the driving gear 1421, the driven gear 1422 is connected to the polarization element 13, and the driving gear 1421 is driven by the driving member 141 to rotate so as to drive the driven gear 1422 to rotate, thereby driving the polarization element 13 to rotate relative to the bracket 11. Further, the driving gear 1421 may be engaged with the driving member 141 through a rotating shaft.

Therefore, the driving member 141 drives the polarization element 13 to rotate relative to the bracket 11 through the driving gear 1421 and the driven gear 1422, which is simple, convenient and easy to implement, and can stabilize and efficiently rotate the polarization element 13, and reduce the cost of the camera assembly 100.

In the example of fig. 13 and 14, the driving gear 1421 may be sleeved on the output shaft 1411 of the driving member 141. Further, a connection port 1423 may be disposed in the middle of the driving gear 1421, and the output shaft 1411 of the driving element 141 is inserted into the connection port 1423. Thus, when the driving member 141 is operated, the driving gear 1421 is driven by the driving member 141 to rotate.

The driven gear 1422 is engaged with the drive gear 1421, the driven gear 1422 is provided on the top wall 111, and the driven gear 1422 rotates relative to the top wall 111 when the drive gear 1421 rotates.

The driven gear 1422 is provided with an accommodating opening 1424, and the accommodating opening 1424 surrounds the opening 111 in a direction perpendicular to the plane of the top wall 111. Thus, the opening 111 is not blocked by the driven gear 1422, thereby preventing the driven gear 1422 from blocking incident light to the opening.

The polarization element 13 is disposed in the receiving opening 1424 and covers the opening 1111 in a direction perpendicular to the plane of the top wall 111. Specifically, the polarizing element 13 occupies a part or all of the space of the accommodating port 1424 in the direction of the plane in which the driven gear 1422 is located. The polarizer 13 may be fixedly connected to the driven gear 1422, i.e., cannot rotate relative to the driven gear 1422, so as to rotate synchronously with the driven gear 1422.

It is understood that in the example of fig. 14 and 14, the driven gear 1422 is disposed on the top wall 111, i.e., the driven gear 1422 is disposed outside the accommodating space 113. The polarizer 13 is disposed in the accommodating opening 1424, and therefore the polarizer 13 is disposed outside the accommodating space 113.

Referring to fig. 15, 16 and 17, in the present embodiment, the driving device 14 may further include a connecting member 143, the connecting member 143 is at least partially disposed in the opening 1111, the connecting member 143 connects the polarization element 13 and the driven gear 1422, and the driving member 141 is configured to drive the driving gear 1421 to rotate so as to drive the driven gear 1422 to rotate, so that the connecting member 143 slides to drive the polarization element 13 to rotate relative to the bracket 11.

So, connect driven gear 1422 and polarization component 13 through connecting piece 143, can avoid driven gear 1422 direct drive polarization component 13 and lead to polarization component 13 to damage, be favorable to improving the reliability of camera module.

Note that the connecting member 143 is disposed at least partially in the opening 1111, meaning that the connecting member 143 surrounds the opening 111 in a direction perpendicular to the plane of the top wall 111.

In the present embodiment, the connection member 143 includes a connection ring 143. Alternatively, the connecting member 143 has a ring shape. In this way, the shape of the connecting member 143 is adapted to the shape of the polarizing element 13, so that the driving device 14 can drive the polarizing element 13 more smoothly.

Specifically, referring to fig. 18, the connecting member 143 is at least partially disposed on the top wall 111, the top wall 111 may be formed with a guide slot 1101, and the connecting member 143 is partially inserted into the guide slot 1101. In this manner, the sliding of the connector 143 on the top wall 111 can be guided by the guide groove 1101, thereby guiding the rotation of the polarization element 13.

In the example of fig. 18, a groove 1431 is formed at one side of the connection member 143, an edge of the polarization member 13 is inserted into the groove 1431, and the driven gear 1422 is disposed at one side of the connection member 143 facing away from the polarization member 13. In other words, the connector 143 is connected to the slot of the polarization element 13.

It can be understood that, since the connecting member 143 is annular, the driven gear 1422 is disposed on a side of the connecting member 143 away from the polarizing element 13, that is, the driven gear 1422 is disposed on an outer side of the connecting member 143. That is, the polarizing element 13, the connector 143, and the driven gear 1422 are arranged in this order from the inside to the outside.

Therefore, the polarizing element 13 is stably connected to the connecting member 143, so that the driving member 141 drives the polarizing element 13 to stably rotate through the gear and the connecting member 143. Specifically, the polarizing element 13 may be clearance-fitted with the groove portion of the connector 143.

In this embodiment, the connecting member 143 may be an injection-molded insert of the driven gear 1422. Thus, the number of parts can be reduced and the mounting efficiency can be improved. It is understood that in other embodiments, the connecting member 143 may be a separate connecting ring, and the connecting member 143 may be connected to the driven gear 1422 first, and then the edge of the polarizer 13 may be inserted into the groove on one side of the connecting member 143.

Referring to fig. 19, 20 and 21, the camera head assembly 10 may further include a cover plate 15. The cover plate 15 covers at least partially the drive means 14. In this way, the cover plate 15 can protect the driving device 14, thereby improving the reliability of the camera assembly 10.

Specifically, the cover plate 15 may be connected to the bracket 11 by an adhesive. Therefore, the connection between the cover plate 15 and the bracket 11 can be simply and conveniently realized, the looseness of the connection between the cover plate 15 and the bracket 11 is avoided, and the connection stability is ensured. Further, the adhesive includes, but is not limited to, double-sided tape, silicone adhesive, photosensitive adhesive, and the like. The specific form of the adhesive is not limited herein.

Note that the cover 15 at least partially covers the driving device 14, and may refer to the cover 15 partially covering the driving device 14, or may refer to the cover 15 completely covering the driving device 14. In the example of fig. 19-21, the cover plate 15 covers the driving member 141, the driving gear 1421, the driven gear 1422, and the connecting member 143 of the driving device 14. In this way, the driving gear 1421, the driven gear 1422, and the connecting member 143 can be protected from deformation.

It is understood that in other examples, the cover plate 15 may cover only the driving member 141 of the driving device 14; or, cover only the drive gear 1421; or, cover only the driven gear 1422. The specific manner in which the cover plate 15 covers the drive device 14 is not limited herein.

The cover plate 15 may also at least partially cover the top wall 111. "the cover plate 15 at least partially covers the top wall 111" may mean that the cover plate 15 partially covers the top wall 111, and may also mean that the cover plate 15 completely covers the top wall 111. In the example of fig. 19-21, the cover 15 covers the top wall 111 entirely. In this way, the strength of the top wall 111 can be increased to protect the rack 11.

In the present embodiment, the cover plate 15 is formed with a through hole 151, and the through hole 151 is disposed corresponding to the opening 1111, so that the polarizing element 13 filters predetermined polarized light passing through the through hole 151. Therefore, the incident light of the camera assembly 10 is prevented from being shielded by the cover plate 15, and the normal operation of the camera 12 can be ensured.

Note that the through hole 151 is disposed corresponding to the opening 1111, which means that the through hole 151 is disposed corresponding to the opening 1111 in a direction perpendicular to a plane of the top wall 111. Further, the projection of the through hole 151 on the top wall 111 is within the opening 1111 or coincides with the opening 1111. Therefore, incident light passing through the through hole 151 can be guaranteed to enter the opening 1111 and enter the camera 12 after being processed by the polarizing element 13, and the light utilization rate is improved.

In addition, the projection of the through hole 151 on the top wall 111 may be within the projection of the polarizing element 13 on the top wall 111 or coincide with the projection of the polarizing element 13 on the top wall 111. Therefore, the incident light passing through the through hole 151 can be guaranteed to be processed by the polarizing element 13, the shooting effect of the camera 12 is guaranteed, and the light which is not processed by the polarizing element 13 is prevented from participating in imaging.

In addition, as mentioned above, the driven gear 1422 is provided with the receiving opening 1424, and the receiving opening 1424 surrounds the opening 111 in a direction perpendicular to the plane of the top wall 111. Based on this, the projection of the through hole 151 on the top wall 111 may be within the projection of the accommodating port 1424 on the top wall 111 or coincide with the projection of the accommodating port 1424 on the top wall 111. Thus, the cover plate 15 can be ensured to completely cover the driven gear 1422, so that the cover plate 15 has a better protection effect on the driven gear 1422.

It is understood that in other embodiments, the cover plate 15 may include a light-transmitting portion and a light-blocking portion, and the light-transmitting portion is provided corresponding to the opening 1111. Therefore, the cover plate 15 is not required to be provided with holes, and the water vapor dust can be prevented from entering the through holes to influence the normal work of the camera 12. Moreover, the light shielding portion can shield the internal elements of the camera assembly 10, and the appearance effect of the camera assembly 10 can be improved.

In addition, the cover plate 15 may be transparent. Thus, inspection and maintenance of the camera assembly 10 is facilitated. It will be appreciated that the cover 15 may also be non-transparent.

In summary, the present embodiment provides a camera assembly 10. The camera assembly 10 comprises a bracket 11, a camera 12 and a polarization element 13, wherein the bracket 11 comprises a top wall 111 and a side wall 112, the top wall 111 is provided with an opening 1111, and the top wall 111 and the side wall 112 are connected to form an accommodating space 113; the camera 12 is arranged in the accommodating space 113; the polarization element 13 is disposed in the opening 1111, and the polarization element 13 can rotate relative to the bracket 11 to filter out predetermined polarized light in the incident light of the camera 12 assembly, so that the camera 12 can image with the filtered incident light.

In the camera assembly 10 of the embodiment of the present application, predetermined polarized light in the incident light of the polarized element 13 filtering camera 12 assembly that can rotate for the support 11 makes the camera 12 utilize the incident light after filtering to form images, can reduce or even eliminate adverse effect of predetermined polarized light to images in the shooting process, is favorable to improving the transparency and the dynamic range of images, thereby improving the image quality.

Referring to fig. 22, a control method is provided in an embodiment of the present application. The control method is for the camera assembly 10. The camera assembly 10 comprises a bracket 11, a camera 12 and a polarization element 13, wherein the bracket 11 comprises a top wall 111 and a side wall 112, the top wall 111 is provided with an opening 1111, and the top wall 111 and the side wall 112 are connected to form an accommodating space 113; the camera 12 is disposed in the accommodating space 113, and the polarization element 13 is disposed in the opening 1111 and can rotate relative to the bracket 11.

The control method comprises the following steps:

step S13: determining the rotation angle of the polarizing element 13;

step S15: the polarization element 13 is controlled to rotate according to the rotation angle to filter out predetermined polarized light in the incident light of the camera assembly 10, so that the camera 12 images by using the filtered incident light.

The camera assembly 10 of the embodiment of the present application further includes a processor 101, and the processor 101 is configured to determine the rotation angle of the polarization element 13; and is used for controlling the rotation of the polarization element 13 according to the rotation angle to filter out the predetermined polarized light in the incident light of the camera assembly 10, so that the camera 12 forms an image by using the filtered incident light.

According to the control method, the preset polarized light in the incident light of the camera 12 component is filtered by the polarizing element 13 capable of rotating relative to the support 11, so that the camera 12 images by using the filtered incident light, the adverse effect of the preset polarized light on the image in the shooting process can be reduced or even eliminated, the image transparency and the dynamic range can be improved, and the image quality can be improved.

Note that the "rotation angle" herein refers to an angle by which the polarizing element 13 needs to be rotated with respect to the initial position.

In step S15, the polarization element 13 may be controlled to rotate from the initial position to the target position after rotating by a certain rotation angle. Therefore, the reference position can be arranged in each rotation, so that the rotation angle can be conveniently determined, and the accuracy of the target position can be ensured.

Further, after each shooting is finished, the polarization element 13 may be controlled to be reset to the initial position for the next rotation. Alternatively, the polarization element 13 is controlled to be reset to the initial position before the polarization element 13 is controlled to rotate according to the rotation angle. In this way, the polarizing element 13 is rotated by a certain rotation angle, and the accuracy of the rotation is ensured.

It is understood that, in step S15, the polarizer 13 may be controlled to rotate from the current position, and after rotating by the deviation angle, the polarizer is controlled to rotate to the target position, so that the angle of the target position relative to the initial position is the rotation angle. In other words, step S15 includes: determining a deviation angle according to the rotation angle and the current position of the polarization element 13; the polarization element 13 is controlled to rotate from the current position to the target position by the deviation angle such that the angle of the target position with respect to the initial position is the rotation angle.

For further explanation and explanation of this part, reference is made to the explanation and explanation of the polarizer 13, and further explanation is omitted here to avoid redundancy.

Referring to fig. 23, in some embodiments, step S13 includes:

step S132: acquiring exposure data of a current scene through the camera 12;

step S134: the rotation angle of the polarizing element 13 is determined from the exposure data.

In some embodiments, the processor 101 is configured to acquire exposure data of a current scene through the camera 12; and for determining the rotation angle of the polarizing element 13 from the exposure data.

In this way, the rotation angle of the polarization element 13 is determined according to the exposure data of the current scene, so that the rotation of the polarization element 13 is adapted to the current scene, thereby improving the imaging quality of the camera assembly 10.

Specifically, in the present embodiment, the exposure data of the current scene includes an exposure histogram. Step S132 may include: acquiring a scene image of a current scene through the camera 12; an exposure histogram is determined from the scene image. Therefore, the exposure data of the current scene can be simply and quickly acquired, and the accuracy is high, so that the subsequent determination of the rotation angle is accurate, and the improvement of the image quality shot by the camera 12 is facilitated.

The abscissa of the exposure histogram represents the lightness of the frame, from left to right representing pure black to pure white: the closer to the left, the darker the picture brightness; the brighter the picture is toward the right. The exposure histogram ordinate represents the number of pixels of different luminance values. Therefore, the exposure condition of the image can be determined by analyzing the brightness distribution of the exposure histogram.

It will be appreciated that in other embodiments, exposure data for the current scene may be acquired by other imaging devices. For example, the camera assembly 10 may further include an imaging module through which exposure data for the current scene is acquired. In this way, the acquisition of exposure data can also be achieved to determine the rotation angle. The specific manner in which the exposure data is acquired is not limited herein.

Referring to fig. 24, in some embodiments, step S134 includes:

step S1342: determining the current light entering amount of the camera 12 according to the exposure data;

step S1344: when the current light incoming amount is larger than a preset threshold value, determining a difference value between the current light incoming amount and the preset threshold value;

step S1346: and determining the rotation angle according to the difference.

In some embodiments, the processor 101 is configured to determine a current light entering amount of the camera 12 according to the exposure data; the method comprises the steps of determining the difference value between the current light incoming amount and a preset threshold value when the current light incoming amount is larger than the preset threshold value; and for determining the angle of rotation from the difference.

In this way, the rotation angle of the polarization element 13 is determined by the difference between the current light-entering amount determined by the exposure data and the preset threshold, so that the rotation angle is adapted to the difference to correct the difference, and thus the light-entering amount after rotation is less than or equal to the preset threshold, which is beneficial to avoiding overexposure to improve the image quality.

It can be understood that when the current light amount is greater than the preset threshold, it may be determined that the image is overexposed, and the image quality is poor, and the predetermined polarized light emitted to the camera 12 needs to be filtered by the rotating polarizing element 13 to reduce the light amount, so as to avoid the image overexposure, and it is beneficial to improve the transparency and dynamic range of the image, thereby improving the image quality.

Specifically, in step S1342, the exposure data may be processed according to a preset processing model to determine the current amount of incoming light. Thus, the current light-entering amount can be determined simply and quickly from the exposure data, and the processing speed can be increased.

In step S1344, the preset threshold may be a default light-entering amount threshold. The preset threshold may also be modified and updated by the user. The specific source of the predetermined threshold is not limited herein.

Referring to fig. 25, in some embodiments, step S1346 includes:

step S1347: determining the type of the preset polarized light to be filtered according to the difference value;

step S1348: the rotation angle is determined according to the type of the predetermined polarized light.

In some embodiments, the processor 101 is configured to determine the type of predetermined polarized light to be filtered out according to the difference value; and for determining the rotation angle in dependence on the type of the predetermined polarized light.

Therefore, the type of the preset polarized light is determined according to the difference value, and the rotation angle is determined according to the type of the preset polarized light, so that the determination of the rotation angle is more accurate, and the filtering effect of the preset polarized light is favorably ensured.

It can be understood that the overexposure conditions are different, i.e. the difference is different, for different objects being photographed. Therefore, the type of predetermined polarized light to be filtered out can be determined from the difference. And the type of polarized light corresponds to the angle that the polarizing element 13 needs to rotate to filter out the type of polarized light, and thus the rotation angle can be determined according to the type of predetermined polarized light.

Moreover, because the angles of the polarized light reflected by the partial objects are similar, and the rotation angles required by the corresponding polarization elements 13 are also similar, the type of the predetermined polarized light to be filtered is determined according to the difference value, and then the rotation angle is determined according to the type of the predetermined polarized light, so that the accuracy of determining the rotation angle can be improved, the predetermined polarized light is more accurately filtered, and the effect is better.

In step S1347, a first preset relationship may be obtained, and the type of the predetermined polarized light to be filtered out is determined according to the first preset relationship and the difference, where the first preset relationship is a corresponding relationship between a preset difference and the type of the predetermined polarized light. In this manner, the type of predetermined polarized light can be quickly and accurately determined from the difference.

In step S1347, the type of the predetermined polarized light may also be determined according to a scene image of the current scene of the camera 12. For example, when the water surface is identified in the scene image, the predetermined polarized light is determined to be water surface reflection polarized light; and determining the predetermined polarized light to be air reflection polarized light when the sky time is identified to be included in the scene image. In this way, the type of predetermined polarized light can be determined more accurately.

Similarly, in step S1348, a second preset relationship may be obtained, and the rotation angle is determined according to the second preset relationship and the type of the predetermined polarized light, where the second preset relationship is a corresponding relationship between the type of the predetermined polarized light and the rotation angle. In this manner, the rotation angle can be quickly and accurately determined according to the type of the predetermined polarized light.

It is understood that in other embodiments, the rotation angle may also be determined according to the difference and a third preset relationship, where the third preset relationship is a preset corresponding relationship between the difference and the rotation angle. In this way, the speed at which the rotation angle is determined from the difference can be increased.

Referring to fig. 26, in some embodiments, step S134 includes:

step S1349: determining the rotation angle and the exposure parameters of the camera 12 according to the exposure data;

the control method comprises the following steps:

step S14: the camera 12 is set according to the exposure parameters.

In some embodiments, the processor 101 is configured to determine the rotation angle and the exposure parameters of the camera 12 according to the exposure data; and for setting the camera 12 according to the exposure parameters.

In this way, the exposure parameters of the camera 12 are set and the polarization rotating element 13 is used to adjust the light entering amount of the camera 12, so that the image quality is further improved. It can be understood that in the case of high contrast, for example, the current scene includes multiple types of reflective objects, the rotating polarization element 13 can only filter out the polarized light caused by one type of reflective object, and the polarized light caused by other types of reflective objects may also cause the image to be overexposed and have poor quality. Therefore, the image quality can be further improved by adjusting the exposure parameters of the camera 12 and the rotating polarization element 13.

In step S1349, a rotation angle may be determined according to the exposure data; controlling the polarization element 13 to rotate according to the rotation angle; and updating the exposure data and determining the exposure parameters according to the updated exposure data. In this way, after the polarization element 13 is rotated, the exposure parameters of the camera 12 are determined based on the updated exposure data, and the accuracy of the rotation angle and the exposure parameters can be improved.

It will be appreciated that the exposure parameters of the camera 12 may also be determined from the exposure data; setting the camera 12 according to the exposure parameters; and updating the exposure data and determining the rotation angle according to the updated exposure data. Therefore, after the exposure parameters are set, the rotation angle is determined according to the updated exposure data, and the accuracy of the rotation angle and the exposure parameters can be improved.

Of course, the rotation angle and the exposure parameters may also be determined simultaneously from the exposure data. Thus, the determination speed is fast, which is beneficial to improving the response speed of the camera assembly 10.

Referring to fig. 27, in some embodiments, step S13 includes:

step S135: acquiring input information;

step S136: the rotation angle of the polarizing element 13 is determined in response to the input information.

In some embodiments, the processor 101 is configured to obtain input information; and for determining the rotation angle of the polarizing element 13 in response to the input information.

Therefore, the user can control the rotation of the polarization element 13 through inputting information, so that the rotation of the polarization element 13 better meets the requirements of the user, the operation feeling of the user can be improved, and the improvement of the user experience is facilitated. It is to be understood that the input information may refer to information input by a user.

In step S135, the input information includes, but is not limited to, voice information, gesture information, touch screen information, knob information, and key information. In other words, the user may input information by voice, gesture, touch screen, knob, key, etc. The specific form and the specific input manner of the input information are not limited herein.

Note that the camera assembly 10 may be used in the electronic device 100. A user may input information through the electronic device 100 by voice, gesture, touch screen, knob, key, etc., so that the camera assembly 10 acquires the input information.

In step S136, the input information may be parsed to determine the rotation angle of the polarizing element 13. For example, in the case where the input information is voice information, voice recognition may be performed on the voice information to determine the rotation angle of the polarization element 13. In the case where the input information is gesture information, the gesture information may be recognized and matched to determine the rotation angle of the polarization element 13.

It will be appreciated that the input information may include angle input information, and may also include parameter input information. Alternatively, the user can adjust the rotation angle of the polarization element 13 by inputting information, and can also adjust the shooting parameters of the camera 12 by inputting information. For example, the exposure time, aperture, and the like of the camera 12 are adjusted. Thus, the shooting parameters of the camera 12 can meet the requirements of the user, and the operation feeling and the user experience of the user are further improved.

Referring to fig. 28, in one example, the user enters the manual mode operation interface by clicking on the "manual mode" icon. In the manual mode, the user can enter a category selection interface for inputting information by clicking an icon of "input parameter". In the category selection interface for inputting information, a user can enter the interface for inputting information by clicking the icon of the rotation angle. In the interface for inputting information at an angle, the user clicks the "ok" icon after inputting the rotation angle of 20 °, so that the driving assembly 14 drives the polarization element 13 to rotate 20 ° from the initial position. After the rotation is completed, the user can enter the shooting interface to shoot.

In another example, referring to fig. 28, a user may enter an automatic mode by clicking on an icon of "automatic mode", camera assembly 10 automatically determines the rotation angle, and controls the polarization element 13 to rotate according to the rotation angle.

The specific manner of determining the rotation angle is not limited herein.

Referring to fig. 29, in some embodiments, the camera assembly 10 is used in an electronic device for prompting a preset shooting mode, which includes an angle parameter of the polarization element 13; step S13 includes:

step S137: acquiring a selection instruction;

step S138: determining the angle parameter of the shooting mode corresponding to the selection instruction;

step S139: and determining the rotation angle according to the angle parameter.

In some embodiments, the processor 101 is configured to fetch a selection instruction; the angle parameter is used for determining the shooting mode corresponding to the selection instruction; and for determining the angle of rotation from the angle parameter.

Therefore, the rotation angle is determined through the shooting mode selected by the user, the situation that the user is difficult to set the rotation angle by himself due to lack of experience can be avoided, the rotation angle can adapt to the requirements of the current scene and the user, and improvement of image quality and user experience are facilitated.

Specifically, in step S137, the user may input a selection instruction through the electronic device 100 by means of voice, gesture, touch screen, knob, key, or the like, so that the camera assembly 10 acquires the selection instruction. The specific form of the selection instruction is not limited herein.

In step S138, the angle parameter may be an angle value or an angle range. In step S139, in the case where the angle parameter is an angle value, the angle parameter may be taken as a rotation angle; in the case of an angle parameter of an angle range, an angle value can be determined from the angle range as the angle of rotation. The specific form of the angle parameter is not limited herein.

In addition, the photographing mode includes, but is not limited to, a mountain mode, a river mode, a stream mode, and a sky mode. The specific type of shooting mode is not limited herein.

It is understood that in the case of selecting the photographing mode, the user may also input photographing parameters of the camera 12, such as shutter time, aperture, and the like, by inputting information. In this way, image quality and user experience may be further improved.

Referring to fig. 30, in one example, the user enters the manual mode operation interface by clicking on the "manual mode" icon. In the manual mode operation interface, the user enters the operation interface for selecting the shooting mode by clicking the icon for "selecting mode". After the user selects the shooting mode as "continuous flowing water", the corresponding angle parameter of the continuous flowing water is acquired to be 20 °, and the driving component 14 drives the polarization element 13 to rotate 20 ° from the initial position. After the rotation is completed, the user can enter the shooting interface to shoot.

Alternatively, the operation mode of the electronic device 100 when shooting may include an automatic mode and a manual mode, and in the case where the operation mode is the automatic mode, the camera assembly 10 automatically determines the rotation angle. In the case that the operation mode is a manual mode, the user may manually input a parameter, such as a rotation angle; or one photographing mode is selected from a plurality of photographing modes to determine the rotation angle according to the angle parameter of the photographing mode.

Referring to fig. 31, in some embodiments, the camera assembly 10 includes an imaging module, and the control method includes:

step S11: acquiring a preview image through the camera 12 and/or the imaging module;

Thus, under the condition that the camera assembly 10 comprises the camera 12 and the imaging module, whether the camera 12 with the rotatable polarization element 13 is started or not is determined according to the preview image, the user does not need to manually select the camera 12, and the improvement of user experience is facilitated. Further, in the case where the current scene determined from the preview image is a preset scene, the camera 12 with the rotatable polarization element 13 is enabled, so that the image quality can be improved. And under the condition that the current scene determined according to the preview image is not the preset scene, starting the imaging module without the rotatable polarizing element 13, so that the power consumption can be reduced.

The specific form of capturing the preview image is not limited herein.

In step S12, determining a current scene from the preview image includes: and identifying a shot object from the preview image, and determining the current scene according to the shot object. For example, when it is recognized from the preview image that the subject is a river, it may be determined that the current scene is a river scene; when it is recognized from the preview image that the subject is a mountain, it may be determined that the current scene is a mountain scene. Therefore, the accuracy of the current scene can be improved.

In this embodiment, the preset scene includes a scene type scene. Such as a mountain scene, a river scene, a stream of people scene, a sky scene. The specific form of the preset scene is not limited herein.
