Description

Technical Field

[0001] This application belongs to the field of camera module technology, and in particular relates to an optical image stabilization mechanism and a camera module. Background Technology

[0002] In some telephoto camera modules, a prism is placed between the lens and the image chip as an optical path folding element to extend the optical path through optical path folding, thereby achieving telephoto shooting. At the same time, in order to improve image stabilization performance, the lens, prism, or image chip is usually moved by the image stabilization mechanism to reduce the impact of shooting shake on the image quality.

[0003] However, since the lens and image chip are often located on the same side of the optical path folding prism, the length and width of the prism often need to be increased to ensure the range of image stabilization movement. This increases the overall size of the telephoto camera module, requiring more installation space and limiting its applicability. Furthermore, because light changes direction multiple times within the prism, pushing the lens can create lighting defects on the image chip side, reducing image quality. On the other hand, the prism is relatively heavy, so moving it often requires a more powerful image stabilization motor, which necessitates increasing the motor's size and further increasing the overall size of the telephoto camera module, hindering the application of telephoto lenses. Summary of the Invention

[0004] This application provides an optical image stabilization mechanism and a camera module, aiming to at least partially solve the technical problems of unsatisfactory optical image stabilization quality in telephoto lens modules and the large size and installation space requirements of the image stabilization mechanism. Therefore,

[0005] One aspect of this application provides an optical image stabilization mechanism, comprising:

[0006] Image stabilization bracket;

[0007] A deformable light-transmitting element is disposed within the anti-shake bracket, and the deformable light-transmitting element is configured with an inlet plane for light to enter and an outlet plane for light to exit.

[0008] An image stabilization drive assembly is connected between the image stabilization bracket and the deformable light-transmitting element to push and pull the deformable light-transmitting element to deform it, thereby changing the normal angle of the light-incoming plane and adjusting the light path of the light passing through the deformable light-transmitting element.

[0009] In some embodiments, the anti-shake drive component is connected to the light-receiving plane to push or pull the light-receiving plane up or down on one side, thereby adjusting the normal angle of the light-receiving plane.

[0010] In some embodiments, the deformable light-transmitting element includes:

[0011] The first base lens has one side configured as the light-incoming plane;

[0012] A deformable light-transmitting material component is attached to the other side of the first base lens.

[0013] In some embodiments, the deformable light-transmitting element further includes a second base lens, one side of which is configured as the light-emitting plane, and the other side is attached to the deformable light-transmitting material.

[0014] In some embodiments, the deformable light-transmitting material can be configured as an elastic light-transmitting material or a liquid light-transmitting material.

[0015] In some embodiments, the image stabilization drive component includes:

[0016] A driving magnet is disposed on the deformable light-transmitting element;

[0017] A drive coil is mounted on the image stabilization bracket, and the drive coil is positioned opposite the drive magnet. By adjusting the current signal applied to the drive coil, the magnitude and direction of the force between the energized drive coil and the drive magnet are adjusted, thereby adjusting the normal angle of the light-gathering plane.

[0018] In some embodiments, there are four driving magnets and four driving coils, and the four driving magnets are equally spaced on the outer edge of the deformable light-transmitting element.

[0019] In another aspect of this application, a camera module is provided, including: a lens, an image chip, and the aforementioned optical image stabilization mechanism;

[0020] The optical image stabilization mechanism is disposed between the lens and the image chip, receives light emitted from the lens, adjusts the optical path, and projects it onto the image chip.

[0021] In some embodiments, the camera module further includes a prism, the lens and the image chip are spaced apart on one side of the prism, the optical image stabilization mechanism is disposed between the lens and the prism, and light emitted from the lens enters the prism and is incident on the image chip after being reflected multiple times in the prism.

[0022] In some embodiments, the prism has an incident surface and an exit surface on the same side. The lens and the optical image stabilization mechanism are disposed on the incident surface side, and the image chip is disposed on the exit surface side. Light enters the prism from the incident surface and exits the prism from the exit surface after multiple reflections in the prism.

[0023] The embodiments of this application have at least the following beneficial effects:

[0024] The optical image stabilization mechanism and camera module provided in this application embodiment are equipped with a deformable light-transmitting element, which is used to adjust the light path of light passing through the deformable light-transmitting element by deformation. The deformable light-transmitting element is provided with a light-inlet plane and a light-outlet plane, so it can be configured in the camera module. By adjusting the normal angle of the light-inlet plane, the light path is adjusted to achieve optical image stabilization compensation and improve shooting quality. An image stabilization bracket is also provided as the basis for image stabilization operation, and an image stabilization driving component is connected between the image stabilization bracket and the deformable light-transmitting element, thereby implementing the deformation of the deformable light-transmitting element and changing the normal angle of the light-inlet plane to achieve the purpose of optical image stabilization. On the other hand, optical image stabilization can be achieved only by in-situ deformation of the deformable light-transmitting element, without the need to move the image chip, lens or prism as in existing image stabilization mechanisms, thereby significantly reducing the space occupied by the image stabilization mechanism, thereby reducing the size of the camera module and helping to expand the scope of application. It is worth noting that the deformation of the deformable light-transmitting element does not require relative displacement between the lens and the prism, ensuring the stability of the light path between the prism and the lens, as well as within the prism. This reduces random reflections and refractions caused by changes in the angle of incident light, thereby reducing the risk of poor lighting defects on the image sensor chip and maintaining image quality.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:

[0041] In some telephoto camera modules, a prism is placed between the lens and the image chip as an optical path folding element to extend the optical path and achieve telephoto shooting. Simultaneously, to improve image stabilization performance, the lens, prism, or image chip is typically moved by the stabilization mechanism to reduce the impact of camera shake on image quality. However, this undoubtedly increases the space occupied by the stabilization mechanism, hindering its application in terminal products with limited installation space. Furthermore, moving the lens can easily increase interference light generated by random reflections and refractions in the prism, causing image ghosting, aperture defects, and other lighting defects, thus affecting image quality.

[0042] Therefore, this application provides an optical image stabilization mechanism and a camera module, which aims to reduce the size of the image stabilization mechanism in the telephoto camera module to a certain extent, improve the image stabilization quality, and reduce interference light and shadow defects caused by image stabilization operation, thereby achieving a balance between small space volume and low risk of light and shadow defects.

[0043] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, the optical image stabilization mechanism 1 is connected to various types of camera modules, such as conventional camera modules, telephoto camera modules, etc., to adjust the optical path, realize optical image stabilization compensation, and improve the image stabilization shooting quality.

[0044] Specifically, the optical image stabilization mechanism 1 may include an image stabilization bracket 11, a deformable light-transmitting element 12, and an image stabilization drive assembly 13; wherein, the deformable light-transmitting element 12 is disposed in the image stabilization bracket 11 and is connected to the image stabilization bracket 11 through the image stabilization drive assembly 13.

[0045] The image stabilization bracket 11 can serve as the basis for the image stabilization operation of the optical image stabilization mechanism 1, providing a strong foundation for image stabilization operation and constraining the position of other components. It can also serve as a connection part for the optical image stabilization mechanism 1 to be installed in the camera module.

[0046] The deformable light-transmitting element 12 is an optical path adjustment element. It can change the angle between the incoming and outgoing light rays by deforming itself, thereby changing the optical path and achieving optical compensation to improve the quality of optical imaging. Specifically, a light-entry plane 121 and a light-exit plane 122 can be respectively provided on two opposite sides of the deformable light-transmitting element 12. The light-entry plane 121 serves as the interface for light to enter, and the light-exit plane 122 serves as the interface for light to exit. Therefore, by causing the deformable light-transmitting element 12 to deform, the normal angle of the light-entry plane 121 can be adjusted, thereby adjusting the optical path passing through the deformable light-transmitting element 12.

[0047] The image stabilization drive component 13 is connected to the image stabilization bracket 11 and the deformable light-transmitting element 12, respectively. The image stabilization bracket 11 can be used as the force base to compress or pull the deformable light-transmitting element 12 to change the angle between the light-inlet plane 121 and the light-outlet plane 122. Thus, by controlling the amplitude and direction of the movement of the image stabilization drive component 13, the normal angle of the light-inlet plane 121 can be flexibly adjusted to implement image stabilization.

[0048] The optical image stabilization mechanism and camera module provided in this application embodiment are equipped with a deformable light-transmitting element, which is used to adjust the light path of light passing through the deformable light-transmitting element by deformation. The deformable light-transmitting element is provided with a light-inlet plane and a light-outlet plane, so it can be configured in the camera module. By adjusting the normal angle of the light-inlet plane, the light path is adjusted to achieve optical image stabilization compensation and improve shooting quality. An image stabilization bracket is also provided as the basis for image stabilization operation, and an image stabilization driving component is connected between the image stabilization bracket and the deformable light-transmitting element, thereby implementing the deformation of the deformable light-transmitting element and changing the normal angle of the light-inlet plane to achieve the purpose of optical image stabilization. On the other hand, optical image stabilization can be achieved only by in-situ deformation of the deformable light-transmitting element, without the need to move the image chip, lens or prism as in existing image stabilization mechanisms, thereby significantly reducing the space occupied by the image stabilization mechanism, thereby reducing the size of the camera module and helping to expand the scope of application. It is worth noting that the deformation of the deformable light-transmitting element does not require relative displacement between the lens and the prism, ensuring the stability of the light path between the prism and the lens, as well as within the prism. This reduces random reflections and refractions caused by changes in the angle of incident light, thereby reducing the risk of poor lighting defects on the image sensor chip and maintaining image quality.

[0049] In some embodiments, the anti-shake drive component 13 can be directly connected to the light-inlet plane 121, thereby pushing and pulling the light-inlet plane 121 to tilt up or tilt down on one side, thereby adjusting the spatial orientation of the light-inlet plane 121. The normal T of the light-inlet plane 121 can be adjusted according to the anti-shake requirements, thereby adjusting the light path of the light passing through the variable light-transmitting element 12.

[0050] It is worth noting that the force application basis of the image stabilization drive component 13 is the image stabilization bracket 11, and after the assembly of the optical image stabilization mechanism 1 is completed, the deformable light-transmitting element 12 should also be in a fixed state. Thus, when the image stabilization drive component 13 is activated, the deformable light-transmitting element 12 can be passively deformed, and the deformation amplitude can be quantified in a preset manner. That is, the change in the direction angle of the light-incoming plane 121 is a controllable quantitative adjustment, thereby enabling precise optical image stabilization.

[0051] The light-receiving plane 121 is a plane, and its normal T is a direction perpendicular to the light-receiving plane 121. In the assembled state, in order to facilitate quantitative control of the direction angle of the light-receiving plane 121, the initial normal T of the light-receiving plane 121 can be set along the optical axis of the lens of the camera module. Therefore, the direction angle of the light-receiving plane 121 can be set as the angle between the normal T of the light-receiving plane 121 and the optical axis of the lens.

[0052] Generally, the deformable light-transmitting element 12 can be installed inside the anti-shake bracket 11, and the light-incoming plane 121 is set to be deformable, so that the light-incoming plane 121 can tilt up and down under the drive of the anti-shake drive assembly 13.

[0053] In some embodiments, the optical path direction within the deformable light-transmitting element 12 can be configured to be the thickness direction of the deformable light-transmitting element 12, and the light-entry plane 121 and the light-exit plane 122 can be disposed on opposite sides of the thickness direction of the deformable light-transmitting element 12. When the optical image stabilization mechanism 1 is installed in the camera module, incident light enters the deformable light-transmitting element 12 from the light-entry plane 121 and exits from the light-exit plane 122.

[0054] Accordingly, the upward and downward directions of the light-inlet plane 121 can be configured to be the thickness direction of the deformable light-transmitting element 12; that is, the anti-shake drive assembly 13 pushes or pulls the light-inlet plane 121 away from or closer to the light-outlet plane 122 along the thickness direction of the deformable light-transmitting element 12.

[0055] In some embodiments, in order to improve the accuracy of the optical path adjustment of the deformable light-transmitting element 12, the deformation of the deformable light-transmitting element 12 can be configured as the deformation of the light-incident plane 121 in the upward and downward directions; thereby, the normal angle of the light-incident plane 121 can be adjusted by the anti-shake driving component 13 pulling up or pressing down on the light-incident plane 121.

[0056] Furthermore, the amplitude of the anti-shake drive component 13 pulling up or pressing down on the light-incoming plane 121 can be further quantified to achieve the purpose of quantifying and adjusting the normal angle of the light-incoming plane 121.

[0057] Generally, the magnitude of the upward or downward movement of the image stabilization drive component 13 on the light-receiving plane 121 can be correlated with the directional angle of the light-receiving plane 121, serving as the basis for implementing image stabilization operations. A series of tests can be conducted by adjusting the upward or downward movement of the light-receiving plane 121 to determine the quantitative correspondence between the magnitude of the upward or downward movement of the image stabilization drive component 13 on the light-receiving plane 121 and the normal angle of the light-receiving plane 121.

[0058] In some embodiments, the area where the light-emitting plane 122 of the deformable light-transmitting element 12 is located can be fixed away from the area where the light-entry plane 121 is located, which simplifies the stress state of the main structure of the deformable light-transmitting element 12, improves the uniformity of the deformation of the deformable light-transmitting element 12, and thereby improves the optical path adjustment accuracy of the deformable light-transmitting element 12.

[0059] In some embodiments, the light-emitting plane 122 can be directly or indirectly attached to a mounting plane, which can limit the deformation range of the area where the light-emitting plane 122 is located, so that the entire light-emitting plane 122 of the deformable light-transmitting element 12 is subjected to uniform force, maintaining its flat shape and thus ensuring its light emission quality. At the same time, it can also be fixed by attaching the light-emitting plane 122 to maintain the stability of the fixed state.

[0060] In some embodiments, the deformable light-transmitting element 12 may include a deformable light-transmitting material 123 and a first base lens 124, wherein one side of the first base lens 124 is configured as the light-inlet plane 121, and the other side is attached to the deformable light-transmitting material 123.

[0061] Generally, the stacking direction of the deformable light-transmitting material 123 and the first base lens 124 is the normal T of the light-incident plane 121. Furthermore, the deformable light-transmitting material 123 can be compressed or stretched along its thickness direction, i.e., the normal T of the light-incident plane 121.

[0062] Accordingly, the image stabilization drive component 13 can be directly connected to the edge of the first base lens 124 and apply an upward or downward force along the thickness direction of the deformable light-transmitting element 123.

[0063] It is worth noting that the first base lens 124 is difficult to deform in its width direction and has good shape stability. Therefore, when the first base lens 124 is attached to the surface of the deformable light-transmitting material 123, it can constrain and limit the deformation of the deformable light-transmitting material 123 in its width direction, thereby maintaining the shape stability of the side where the light-incoming plane 121 is located and maintaining the optical path adjustment accuracy.

[0064] Typically, the first base lens 124 can be bonded to the deformable light-transmitting material 123 using a high-transmittance adhesive material.

[0065] In some embodiments, the material of the deformable light-transmitting material component 123 can be configured as an elastic light-transmitting material, such as light-transmitting rubber. The material of the deformable light-transmitting material component 123 can also be a liquid light-transmitting material with a certain viscosity and fluidity to meet the requirements of deformation and light transmission. Alternatively, a deformable light-transmitting bladder can be used to load the light-transmitting liquid material, thereby achieving both deformation and light transmission functions.

[0066] Generally, the material of the deformable light-transmitting material 123 is usually a polymer material, such as polyolefins or aromatic polyimides. These polymer materials have good heat resistance and high-temperature stability, and can maintain their mechanical properties and optical properties at different temperatures.

[0067] In some embodiments, to further improve the optical path adjustment and control accuracy of the deformable light-transmitting element 12, the deformable light-transmitting element 12 may further include a second base lens 125. One side of the second base lens 125 is configured as the light-emitting plane 122, and the other side can be attached to the other side of the deformable light-transmitting material 123 in the thickness direction. That is, the second base lens 125 and the first base lens 124 are respectively attached to the two sides of the deformable light-transmitting material 123 in the thickness direction along the normal T of the light-incident plane 121, thereby enabling them to synergistically limit the deformation uniformity and amplitude of the deformable light-transmitting material 123 in the width direction.

[0068] At the same time, the second base lens 125 can also form a relatively stable light emission interface to ensure the quality of light emission.

[0069] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 In some embodiments, the anti-shake drive component 13 can be implemented using the principle of a current-carrying coil being subjected to force in a magnetic field. By adjusting the magnitude and direction of the current loaded on the current-carrying coil, the magnitude and direction of the force output by the anti-shake drive component 13 can be adjusted.

[0070] The image stabilization drive assembly 13 may include a drive magnet 131 and a drive coil 132. The drive magnet 131 may be disposed on the deformable light-transmitting element 12, and the drive coil 132 may be disposed on the image stabilization bracket 11. The drive magnet 131 and the drive coil 132 are disposed opposite to each other, and the direction of the force between the drive magnet 131 and the energized drive coil 132 is configured to be along the direction of the deformable light-transmitting element 12.

[0071] It is worth noting that the driving magnet 131 is a passive device, and its installation on the deformable light-transmitting element 12 does not require the configuration of auxiliary components such as power supply lines, thereby reducing the risk of interference with the deformable light-transmitting element 12.

[0072] In some embodiments, in order to facilitate the adjustment of the deformation uniformity and driving capability of the deformable light-transmitting element 12, the number of the driving magnet 131 and the driving coil 132 can be set to four. The four driving magnets 131 can be equally spaced on the outer side of the deformable light-transmitting element 12, and the four driving coils 132 can also be equally spaced on the anti-shake bracket 11, located around the deformable light-transmitting element 12, thereby enabling four-point force application and improving the deformation accuracy of the deformable light-transmitting element 12.

[0073] In some embodiments, the current signals applied to the four drive coils 132 can be differentiated, so that the direction and magnitude of the force applied to each drive magnet 131 may be different, and can be adjusted as needed.

[0074] When adjusting the normal angle of the first base lens 124, this can be achieved by driving one side of the first base lens 124 to tilt up and the other side to tilt down. Specifically, the two driving coils 132 located on opposite sides of the deformable light-transmitting element 12 can be driven with currents in different directions, so that the light-gathering plane 121 is subjected to two forces in opposite directions, i.e., one side is subjected to an upward pulling force and the other side is subjected to a downward pressing force, causing the spatial orientation of the first base lens 124 to change. Of course, the magnitude and direction of the current applied to the driving coils 132 located on the other two outer sides can be flexibly selected, i.e., no current signal can be applied or a current signal can be applied, so that the first base lens 124 is subjected to an upward or downward pulling force, which is used to maintain the smoothness of the orientation change of the first base lens 124 during the operation process and avoid large jumps that affect the image quality; for example, it can limit the reflection and refraction of stray light and shadows caused by large changes in the optical path.

[0075] In some embodiments, to facilitate the installation of the driving magnet 131, a magnet bracket 133 may be bonded to the edge of the first base lens 124, and the driving magnet 131 may be bonded to the magnet bracket 133.

[0076] Generally, the area on the magnet holder 133 where the driving magnet 131 is mounted can be extended beyond the range of the first base lens 124 to reduce the risk of interference and light blocking.

[0077] See Figure 2 In some embodiments, a camera module is also provided, including a lens 2, an image chip 3, and the aforementioned optical image stabilization mechanism 1. The optical image stabilization mechanism 1 is disposed between the lens 2 and the image chip 3, receives light emitted from the lens 2, adjusts the optical path, and projects it onto the image chip 3.

[0078] See Figure 3 , Figure 4 and Figure 6 In some embodiments, a camera module is also provided, including a lens 2, an image chip 3, a prism 4, and the aforementioned optical image stabilization mechanism 1. The lens and the image chip 3 are disposed on the same side of the prism 4, and the optical image stabilization mechanism 1 is disposed between the lens 2 and the prism 4, so that the light passing through the lens 2, after being adjusted by the optical image stabilization mechanism 1, enters the prism 4, and is then projected onto the image chip 3 after multiple reflections by the prism 4.

[0079] Generally, the initial state of the optical image stabilization mechanism 1 is such that the light-inlet plane 121 and the light-outlet plane 122 are perpendicular to the optical axis of the lens 2. When the optical image stabilization mechanism 1 is not activated, the incident light F passes through the lens 2, then enters the deformable light-transmitting element 12 perpendicularly, and then enters the prism 4 perpendicularly. After multiple reflections, it exits the prism 4 perpendicularly and is then projected onto the image chip 3.

[0080] When the optical image stabilization mechanism 1 is activated, the incident light F enters the deformable light-transmitting element 12 from the light-inlet plane 121 in a non-perpendicular state, thereby changing the light path through the deformable light-transmitting element 12 to form a compensated light F1, and then being projected onto the image chip 3 after the light path is extended by the prism 4.

[0081] Generally, the light-emitting plane 122 can be directly bonded to the light-incoming side of the prism 4 using an adhesive material. The prism 4 is fixed to the inside of the camera module by a prism bracket 41, and the image stabilization bracket 11 can be connected to the prism bracket 41, thereby fixing the optical image stabilization mechanism 1 inside the camera module.

[0082] In some embodiments, an incident surface 45 and an exit surface 46 may be provided on one side of the prism 4. Light rays are transmitted into the prism 4 through the incident surface 45, and after multiple reflections in the prism 4, the light rays exit the prism 4 through the exit surface 46.

[0083] In the assembled state, the optical image stabilization mechanism 1 can be correspondingly bonded to the incident surface 45, and the image chip 3 is correspondingly disposed on one side of the exit surface 46. That is to say, the lens 2, the image chip 3, and the optical image stabilization mechanism 1 are located on the same side of the prism 4.

[0084] Generally, the prism 4 is also provided with multiple reflective surfaces for reflecting imaging light. Specifically, the prism 4 may be provided with a first reflective surface 42, a second reflective surface 43, and a third reflective surface 44. Light rays transmitted into the prism 4 from the incident surface 45 are reflected sequentially by the first reflective surface 42, the second reflective surface 43, and the third reflective surface 44, and then exit the prism 4 from the exit surface 46.

[0085] In some embodiments, the second reflective surface 43 may be disposed between the first reflective surface 42 and the third reflective surface 44, and the second reflective surface 43 may be disposed between the incident surface 45 and the exit surface 46.

[0086] In some embodiments, the shape of the prism 4 and the number of reflecting surfaces can be flexibly set according to actual assembly requirements; for example, light is reflected twice in the prism 4, so only a first reflecting surface 42 and a third reflecting surface 44 can be provided in the prism 4. Light rays entering from the incident surface 45 are reflected sequentially on the first reflecting surface 42 and the third reflecting surface 44, and then exit from the exit surface 46.

[0087] In other embodiments, four reflecting surfaces may be provided in the prism 4, namely, the first reflecting surface 42, the second reflecting surface 43, the third reflecting surface 44, and the fourth reflecting surface 47 are provided in the prism 4. The second reflecting surface 43 and the fourth reflecting surface 47 may be arranged opposite to each other and located between the first reflecting surface 42 and the third reflecting surface 44. Light rays incident from the incident surface 45 are reflected sequentially by the first reflecting surface 42, the second reflecting surface 43, the fourth reflecting surface 47, and the third reflecting surface 44, and then exit from the exit surface 46.

[0088] Of course, the number of reflective surfaces can be five or even more, but we will not list them all here.

[0089] In some embodiments, the image stabilization bracket 11 may be configured as a cylindrical component, which fixes the lens 2 and the drive coil 132 together inside the image stabilization bracket 11.

[0090] Correspondingly, the deformable light-transmitting element 12 can also be disposed inside the anti-shake bracket 11 to block interfering stray light.

[0091] In some embodiments, a filter 5 may be provided on the light-incoming side of the image chip 3 to filter out interfering light.

[0092] In some embodiments, the mounting position of the optical image stabilization mechanism 1 can be changed to obtain another implementation scheme of the camera module.
