[0043] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0044] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] The lens assembly, anti-shake shooting method and device, electronic device and storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0046] Combination Figure 1 and Figure 2 As shown, in some embodiments of the present application, a lens assembly is provided, and the lens assembly includes: a housing 110, a lens 120, an image sensor 130, a liquid crystal assembly 140, and a voltage assembly. The lens 120, the image sensor 130, and the liquid crystal assembly 140 are connected to the housing 110, the image sensor 130 is arranged corresponding to the lens 120, and the liquid crystal assembly 140 is located between the lens 120 and the image sensor 130; the voltage assembly is electrically connected to the image sensor and the liquid crystal assembly, and the voltage assembly changes the refractive index of the liquid crystal assembly according to the image received by the image sensor.

[0047] The lens 120, the image sensor 130 and the liquid crystal assembly 140 are all connected to the housing 110, so the relative positions of the lens 120, the image sensor 130 and the liquid crystal assembly 140 are not easily changed. The liquid crystal assembly 140 is located between the lens 120 and the image sensor 130. After the light passes through the lens 120 and the liquid crystal assembly 140 in sequence, the light is irradiated onto the image sensor 130, and the image sensor 130 can collect an image.

[0048] When external light shines on the image sensor 130, the external light forms a light spot on the image sensor 130. The image sensor 130 can intercept the part within the light spot for imaging. When the user's hand shakes when holding the electronic device, the position of the light spot and the photosensitive chip remains unchanged, while the picture inside the light spot changes, so the imaging picture of the image sensor 130 also changes. Therefore, by moving the light spot so that the picture inside the light spot does not change, the anti-shake function can be achieved.

[0049] When no voltage is applied to the liquid crystal component 140, the refractive index of the liquid crystal component 140 for the light is fixed when the light passes through the liquid crystal component 140. When a voltage is applied to the liquid crystal component 140, the liquid crystal component 140 can change the refractive index of the light. Since the liquid crystal component 140 is located between the lens 120 and the image sensor 130, the refractive angle of the light passing through the liquid crystal component 140 is changed by changing the refractive index of the liquid crystal component 140, and the light spot moves on the image sensor 130. When the image in the light spot is consistent with the image before the shake, the anti-shake function is achieved.

[0050] When the voltage applied to the liquid crystal component 140 is different, the refractive index of the liquid crystal component 140 is also different. Therefore, when the amplitude of camera shake is different, the voltage applied to the liquid crystal component 140 is changed accordingly, so that a precise anti-shake function can be achieved under different shake amplitudes.

[0051] The anti-shake function is achieved by changing the refractive index of the liquid crystal component 140, and there is no need to set up moving parts in the camera component. Therefore, the camera component will not be broken due to collision of moving parts, thereby reducing the damage rate of the lens 120 and the image sensor 130, which is beneficial to improving the service life of the camera component.

[0052] The voltage component is electrically connected to the image sensor 130 , and the voltage component is electrically connected to the liquid crystal component 140 , so the voltage component can determine the input voltage to the liquid crystal component 140 according to the degree of image jitter.

[0053] In a possible application, the voltage component is a voltage input circuit, and the voltage input circuit can change the input voltage of the liquid crystal component 140 .

[0054] Moreover, this anti-shake solution does not require moving parts, avoiding the resonance problems, magnetic interference problems, and low anti-shake frequency problems of traditional cameras.

[0055] In a possible application, the image sensor 130 is a photosensitive chip.

[0056] Combination Figure 1 and Figure 2 As shown, in a possible embodiment, the liquid crystal assembly 140 includes: a light-transmitting member 141 and a liquid crystal film 142, the light-transmitting member 141 is connected to the housing 110, the liquid crystal film 142 is arranged on the light-transmitting member 141, and the refractive index of the light-transmitting member 141 is associated with the input voltage of the light-transmitting member 141.

[0057] The light-transmitting member 141 is mounted on the housing 110 , so the relative positions of the light-transmitting member 141 and the housing 110 are not easily changed. The liquid crystal film 142 is disposed on the light-transmitting member 141 , and the light-transmitting member 141 supports the liquid crystal film 142 .

[0058] The thickness of the liquid crystal film 142 is usually set to be relatively thin, so the liquid crystal film 142 is prone to deformation, resulting in a change in the refraction angle of light even when no voltage is applied to the liquid crystal film 142. The liquid crystal film 142 is supported by the light-transmitting component 141, and the liquid crystal film 142 is attached to the light-transmitting component 141, so the shape of the liquid crystal film 142 is not easy to change. When no voltage is applied to the liquid crystal film 142, the refractive index of the liquid crystal film 142 will not change, thereby improving the stability of the anti-shake function.

[0059] like Figure 3 As shown, in a possible application, the liquid crystal film 142 is composed of a substrate 144, an electrode 145 and a liquid crystal layer 146, all of which are made of light-transmitting materials. By applying voltage to the two electrodes 145, the orientation of the liquid crystal molecules changes, causing the refractive index of the liquid crystal component 140 to change.

[0060] like Figure 2 As shown, in a possible embodiment, the light-transmitting element 141 includes: a lens, the lens is provided with a mounting curved surface, and the liquid crystal film 142 is provided on the mounting curved surface.

[0061] The lens is provided with a mounting curved surface. When the liquid crystal film 142 is attached to the mounting curved surface, the liquid crystal film 142 is also curved.

[0062] If the liquid crystal film 142 is a flat plate structure, the travel of the moving light spot will be very effective. Therefore, the light-transmitting element 141 is set as a lens, and the liquid crystal film 142 can be fixed in a curved shape, thereby improving the moving travel of the liquid crystal film 142 for the light spot.

[0063] In one possible application, the lens may be a convex lens or a concave lens.

[0064] Combination Figure 4 and Figure 5 As shown, in a possible embodiment, the liquid crystal film 142 includes: a plurality of liquid crystals 143, the input voltages of the plurality of liquid crystals 143 form a voltage array, and the voltage component changes the input voltage of the liquid crystal film 142 according to the voltage array.

[0065] The multiple liquid crystals 143 in the liquid crystal film 142 are independent of each other, so each liquid crystal 143 has its own upper electrode 145 and lower electrode 145, so that each liquid crystal 143 can be independently applied with a voltage to change the refractive index.

[0066] The combination of input voltages of multiple liquid crystals 143 is called a voltage array. The input voltages of different liquid crystals 143 may be different, which makes the multiple liquid crystals 143 have a combination of multiple input voltages, which can more flexibly and accurately adjust the position of the light spot, which is conducive to improving the anti-shake effect.

[0067] In an embodiment of the present application, an electronic device is provided, comprising: a lens assembly as in any of the above embodiments. Therefore, the electronic device provided in this embodiment can achieve the technical effects in any of the above embodiments, which will not be described in detail here.

[0068] like Figure 6 As shown, in some embodiments of the present application, a method for anti-shake shooting is provided, which is used in the electronic device in the above embodiment, and the method for anti-shake shooting includes:

[0069] Step 202, in shooting mode, obtaining a preview image received by an image sensor;

[0070] Step 204, determining a jitter offset value corresponding to the preview image;

[0071] Step 206, determining a voltage array of a liquid crystal component according to the jitter offset value, the liquid crystal component including a plurality of liquid crystals, the voltage array including input voltages of the plurality of liquid crystals, and the voltage array being associated with the offset value;

[0072] Step 208, applying a voltage array to the liquid crystal component;

[0073] Step 210: photograph and obtain a target image.

[0074] When no voltage is applied to the liquid crystal component, when light passes through the liquid crystal component, the liquid crystal component will not change the refractive index of the light, or will only change the refractive index of the light at a smaller angle. When voltage is applied to the liquid crystal component, the liquid crystal component can change the refractive index of the light. Since the liquid crystal component is located between the lens and the image sensor, by changing the refractive index of the liquid crystal component, the refractive angle of the light passing through the liquid crystal component is changed, and the light spot will move on the image sensor. When the image in the light spot is consistent with the image before the shake, the anti-shake function is achieved.

[0075] The combination of voltages of multiple liquid crystals is called a voltage array. The input voltages of different liquid crystals may be different, which allows multiple liquid crystals to have multiple input voltage combinations, which can more flexibly and accurately adjust the position of the light spot, which is conducive to improving the anti-shake effect.

[0076] In shooting mode, it is necessary to determine whether the camera component has shaken. If the camera component has shaken, the position of the image received by the image sensor will change. At this time, it is necessary to determine the jitter offset value of the image before and after the shake. Different jitter offset values ​​correspond to different voltage arrays. Therefore, when the offset value corresponding to the image is determined, the voltage array that needs to be input to the liquid crystal component is determined. After the liquid crystal component is input with this voltage array, the position of the light spot can be adjusted to achieve the anti-shake function, so that the captured target image has a better shooting effect.

[0077] The voltage array corresponding to the jitter offset value means that, under the current jitter offset value, the corresponding voltage array is input into the liquid crystal component, so that the image in the light spot can be adjusted to be consistent with the image before the jitter.

[0078] When the voltage applied to the liquid crystal component is different, the refractive index of the liquid crystal component is also different. Therefore, when the amplitude of camera shake is different, the voltage applied to the liquid crystal component is changed accordingly, so that accurate anti-shake function can be achieved under different shake amplitudes.

[0079] The anti-shake function is achieved by changing the refractive index of the liquid crystal component. There is no need to set up moving parts in the camera component. Therefore, the camera component will not be broken due to collision of moving parts, thereby reducing the damage rate of the lens and image sensor, which is beneficial to increasing the service life of the camera component.

[0080] In a possible embodiment, before obtaining the jitter offset value of the image received by the image sensor within a set time length, the anti-shake shooting method also includes: obtaining a first calibration image received by the image sensor; determining a second calibration image of the first calibration image under the jitter offset value; applying a voltage array to the liquid crystal component to adjust the imaging position of the second calibration image on the image sensor; updating the jitter offset value according to the first calibration image and the second calibration image; and updating the voltage array according to the updated jitter offset value until the offset of the first calibration image and the second calibration image on the image sensor is zero.

[0081] In order to accurately adjust the light spot position, the corresponding relationship between the jitter offset value and the voltage array needs to be calibrated, that is, the voltage array corresponding to different jitter offset values ​​needs to be determined.

[0082] During the calibration process, the first calibration image is first obtained. The first calibration image is the image before the camera component is shaken. A jitter offset value is set for the camera component, and then a voltage array is randomly applied to the liquid crystal component. This voltage array causes the refractive index of the liquid crystal component to change, thereby generating different images on the image sensor. This image can be defined as: the image after the spot displacement, that is, the second calibration image, and then the first calibration image and the second calibration image are subtracted to determine the offset degree of the first calibration image and the second calibration image. At this time, it is necessary to update the jitter offset value of the first calibration image and the second calibration image to determine whether the offset of the first calibration image and the second calibration image increases or decreases, so as to update the voltage array again to continuously reduce the difference between the first calibration image and the second calibration image. By adjusting the voltage array multiple times, when the difference between the first calibration image and the second calibration image is zero, that is, the offset of the first calibration image and the second calibration image is zero, the voltage array corresponding to the jitter offset value set at the beginning is obtained. By setting different jitter offset values, voltage arrays corresponding to different jitter offset values ​​can be obtained. When used on a camera component, if a jitter offset value is detected, the corresponding voltage array is directly called, and the corresponding voltage array is input to the liquid crystal component to achieve the anti-shake function.

[0083] The anti-shake shooting method provided in the embodiment of the present application can be executed by an anti-shake shooting device. In the embodiment of the present application, an anti-shake shooting device executing the anti-shake shooting method is taken as an example to illustrate the anti-shake shooting device provided in the embodiment of the present application.

[0084] like Figure 7 As shown, in an embodiment of the present application, an anti-shake shooting device 300 is proposed, and the anti-shake shooting device includes:

[0085] The acquisition module 310 is used to acquire the preview image received by the image sensor in the shooting mode;

[0086] A determination module 320, configured to determine a jitter offset value corresponding to the preview image;

[0087] The determination module is further used to: determine a voltage array of a liquid crystal component according to the jitter offset value, the liquid crystal component includes a plurality of liquid crystals, the voltage array includes input voltages of the plurality of liquid crystals, and the voltage array is associated with the offset value;

[0088] A voltage module 330, used to apply a voltage array to the liquid crystal component;

[0089] The shooting module 340 is used to shoot and obtain a target image.

[0090] When the voltage applied to the liquid crystal component is different, the refractive index of the liquid crystal component is also different. Therefore, when the amplitude of camera shake is different, the voltage applied to the liquid crystal component is changed accordingly, so that accurate anti-shake function can be achieved under different shake amplitudes.

[0091] The anti-shake function is achieved by changing the refractive index of the liquid crystal component. There is no need to set up moving parts in the camera component. Therefore, the camera component will not be broken due to collision of moving parts, thereby reducing the damage rate of the lens and image sensor, which is beneficial to increasing the service life of the camera component.

[0092] In a possible embodiment, the anti-shake shooting device also includes: an updating module; before obtaining the jitter offset value of the image received by the image sensor within a set time length: the obtaining module is also used to: obtain the first calibration image received by the image sensor; the determining module is also used to: determine the second calibration image of the first calibration image under the jitter offset value; the voltage module is also used to: apply a voltage array to the liquid crystal component to adjust the imaging position of the second calibration image on the image sensor; the updating module is used to: update the jitter offset value according to the first calibration image and the second calibration image; the updating module is also used to: update the voltage array according to the updated jitter offset value until the offset of the first calibration image and the second calibration image on the image sensor is zero.

[0093] The anti-shake shooting device in the embodiment of the present application can be an electronic device, or a component in the electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal, or other devices other than a terminal. Exemplarily, the electronic device can be a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a mobile Internet device (Mobile Internet Device, MID), an augmented reality (augmented reality, AR) / virtual reality (virtual reality, VR) device, a robot, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook or a personal digital assistant (personal digital assistant, PDA), etc. It can also be a server, a network attached storage (Network Attached Storage, NAS), a personal computer (personal computer, PC), a television (television, TV), a teller machine or a self-service machine, etc., and the embodiment of the present application does not specifically limit it.

[0094] The anti-shake shooting device in the embodiment of the present application may be a device having an operating system. The operating system may be an Android operating system, an iOS operating system, or other possible operating systems, which are not specifically limited in the embodiment of the present application.

[0095] The anti-shake shooting device provided in the embodiment of the present application can implement each process implemented in the above method embodiment, and will not be described again here to avoid repetition.

[0096] Alternatively, if Figure 8 As shown, an embodiment of the present application further provides an electronic device 400, including a processor 401 and a memory 402, wherein the memory 402 stores programs or instructions that can be executed on the processor 401, and when the program or instructions are executed by the processor 401, the various steps of the above-mentioned lens assembly embodiment are implemented, and the same technical effect can be achieved. To avoid repetition, they are not described here.

[0097] It should be noted that the electronic devices in the embodiments of the present application include the above-mentioned mobile electronic devices and non-mobile electronic devices.

[0098] Fig. 9 A schematic diagram of the hardware structure of an electronic device implementing an embodiment of the present application.

[0099] The electronic device 500 includes but is not limited to: a radio frequency unit 501, a network module 502, an audio output unit 503, an input unit 504, a sensor 505, a display unit 506, a user input unit 507, an interface unit 508, a memory 509, and a processor 510.

[0102] When the voltage applied to the liquid crystal component is different, the refractive index of the liquid crystal component is also different. Therefore, when the amplitude of camera shake is different, the voltage applied to the liquid crystal component is changed accordingly, so that accurate anti-shake function can be achieved under different shake amplitudes.

[0103] The anti-shake function is achieved by changing the refractive index of the liquid crystal component. There is no need to set up moving parts in the camera component. Therefore, the camera component will not be broken due to collision of moving parts, thereby reducing the damage rate of the lens and image sensor, which is beneficial to increasing the service life of the camera component.

[0105] By setting different jitter offset values, voltage arrays corresponding to different jitter offset values ​​can be obtained. When used on a camera component, if a jitter offset value is detected, the corresponding voltage array is directly called, and the corresponding voltage array is input to the liquid crystal component to achieve the anti-shake function.

[0106] It should be understood that in the embodiment of the present application, the input unit 504 may include a graphics processor (GPU) 5041 and a microphone 5042, and the graphics processor 5041 processes the image data of a static picture or video obtained by an image capture device (such as a camera) in a video capture mode or an image capture mode. The display unit 506 may include a display panel 5061, and the display panel 5061 may be configured in the form of a liquid crystal display, an organic light emitting diode, etc. The user input unit 507 includes a touch panel 5071 and at least one of other input devices 5072.
