The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The following describes a liquid camera detection apparatus 100 provided in an embodiment of the present application with reference to fig. 1 to 6.

As shown in fig. 1, a liquid camera detection apparatus 100 according to an embodiment of the present application includes: a jig 500, an infrared transmitter 510, and an infrared receiver 520; the clamp 500 is used for clamping the liquid camera 410; and an infrared transmitter 510 and an infrared receiver 520 disposed on a sidewall of the jig 500.

The liquid camera comprises a liquid lens, when the liquid camera is clamped in the clamp 500, the infrared emitter 510 emits a first infrared signal, the first infrared signal is received by the infrared receiver 520 after being reflected or transmitted by the liquid lens, the infrared receiver 520 receives a second infrared signal, and liquid lens leakage is determined under the condition that a first ratio of the first infrared signal to the second infrared signal meets a first preset relation.

In this embodiment, the clamp 500 may be tubular, and the shape of the cross section of the clamp 500 is matched with the shape of the liquid camera.

Illustratively, the liquid camera may include a housing 400, and the housing 400 may be tubular and include two oppositely disposed open ends. The liquid lens is located in the housing 400, and may be located in the middle of the housing 400, or at the end of the housing 400, or near the end of the housing 400.

Illustratively, as shown in fig. 4, the liquid lens 410 includes a liquid lens film 411, in which a liquid lens liquid is wrapped.

Illustratively, the liquid camera may be disposed in the middle of the fixture 500, or at an end of the fixture 500, or near an end of the fixture 500. For example, the housing 400 of the liquid camera may be provided at the middle of the jig 500.

In this embodiment, when the infrared emitter 510 and the infrared receiver 520 are disposed on the sidewall of the fixture 500, the first infrared signal emitted by the infrared emitter 510 can be received by the infrared receiver 520 through the reflection of the liquid lens 411 or the second infrared signal after transmission.

A first possible implementation:

in this embodiment, the first ratio of the first infrared signal to the second infrared signal is an infrared parameter of the liquid lens.

It can be understood that the infrared parameters of the liquid lens during deformation and the infrared parameters during deformation both meet an interval under the condition of no liquid leakage, that is to say, both meet a preset relationship. That is, the first preset relationship of the numerical value corresponding to the infrared parameter when the infrared parameter is not deformed may be the same as or different from the first preset relationship of the numerical value corresponding to the infrared parameter when the infrared parameter is deformed.

In the embodiment of the application, the first proportion of the liquid lens when the liquid lens is not deformed and the first proportion of the liquid lens when the liquid lens is deformed can be detected and stored in advance under the condition that liquid does not leak. Therefore, whether the infrared parameters meet the corresponding first preset relation or not can be determined according to the infrared parameters (namely the first proportion of the first infrared signal and the second infrared signal) detected by the liquid camera detection device, and whether the liquid lens leaks or not can be accurately determined.

In this application embodiment, the numerical value that infrared parameter when liquid camera lens is out of shape corresponds, the numerical value that infrared parameter when including the different deformation of liquid camera lens corresponds. The focal length of the liquid lens can be adjusted by controlling the deformation of the liquid lens. Therefore, the numerical values corresponding to the infrared parameters when the liquid lens deforms include: and the liquid lens has numerical values corresponding to the infrared parameters under different focal lengths.

A second possible implementation:

in this embodiment, the infrared parameter of the liquid lens may also be the intensity of the second infrared signal.

Similarly, it can be understood that the liquid lens meets an interval in the non-deformation infrared parameter and the deformation infrared parameter under the non-leakage condition, that is, the strength of the second infrared signal under the non-deformation condition and the strength of the second infrared signal under the deformation condition of the liquid lens both meet a preset relationship.

The first preset relationship of the numerical value corresponding to the infrared parameter when the infrared parameter is not deformed may be the same as or different from the first preset relationship of the numerical value corresponding to the infrared parameter when the infrared parameter is deformed.

In the embodiment of the application, the strength of the second infrared signal when the liquid lens is not deformed and the strength of the second infrared signal when the liquid lens is deformed can be detected and stored in advance under the condition of no liquid leakage. Therefore, whether the infrared parameters meet the corresponding first preset relation or not can be determined according to the infrared parameters (namely the intensity of the second infrared signals) detected by the liquid camera detection device, and whether the liquid lens leaks or not can be accurately determined.

It can be understood, among two kinds of above-mentioned possible implementation, when liquid camera detection device detected the infrared parameter of liquid camera lens, compare when liquid camera lens is not damaged, when liquid camera lens takes place the damage, the camber change of liquid camera lens, the first infrared signal of infra-red transmitter transmission changes through the transmission angle transmission of liquid camera lens, and, the signal intensity through liquid camera lens transmission also can change, and then, the intensity of the second infrared signal that infrared receiver received will change, through received second infrared signal, can confirm infrared parameter, compare with the first predetermined relation that corresponds through this infrared parameter, can confirm whether liquid camera lens leaks.

The liquid camera detection device that this application embodiment provided can detect the infrared parameter of liquid camera lens (promptly first infrared signal with the first proportion of second infrared signal) through infra-red transmitter and infrared receiver, owing to when liquid camera lens weeping or not weeping, the infrared parameter that corresponds is different. Therefore, whether the liquid lens leaks or not can be quickly and accurately determined according to the detected infrared parameters. Therefore, in the application of the embodiment, the liquid lens leakage can be prevented from damaging the liquid camera and the corresponding circuit board in the use process of the liquid camera.

Optionally, in this embodiment of the application, with reference to fig. 1, as shown in fig. 2, the liquid camera includes a housing 400 and a driving unit 420, and the liquid lens is disposed in the housing 400; the jig 500 includes: a clamping portion for clamping the housing 400; a fixing part 530, wherein the fixing part 530 is arranged in the clamping part, and the infrared emitter 510 and the infrared receiver 520 are both arranged on the fixing part 530; and the power supply port is used for connecting the first interface of the liquid camera.

Under the condition that the power supply port is connected with the first interface, the liquid camera detection device can supply power to the first interface through the power supply port, so as to drive the liquid lens to deform through the driving unit 420.

It can be understood that the first interface of the liquid camera is electrically connected to the driving unit 420.

In one possible example, the clamping portion may include a boss provided on an inner sidewall of the clamp 500, and the boss is used for clamping and fixing the housing 400, so that the clamp 500 clamps the liquid camera.

In one possible example, the clamping portion may include a groove formed on an inner sidewall of the clamp 500, and the groove is used for clamping the housing 400, so that the clamp 500 clamps the liquid camera.

In one possible example, the clamping portion may include a bolt, the outer side wall of the housing is provided with a blind hole, a through hole is formed in the clamp corresponding to the blind hole, and the bolt may penetrate the blind hole through the through hole to fix the housing in the clamp, so that the clamp clamps the liquid camera.

Illustratively, the clamp includes a first sub-clamp and a second sub-clamp, and the outer case is provided at the outer circumference thereof with a connecting piece, and when the liquid-state camera is clamped in the clamp, the connecting piece is located between the first sub-clamp and the second sub-clamp 500, so that the first sub-clamp and the second sub-clamp the connecting piece, thereby clamping the liquid-state camera.

Illustratively, the power supply port may be provided on a sidewall of the jig 500.

Illustratively, the fixing portion 530 may be provided at a sidewall of the jig 500, and the infrared transmitter 510 and the infrared receiver 520 are provided at the fixing portion 530. That is, the infrared transmitter 510 and the infrared receiver 520 may be provided to the sidewall of the jig 500 through the fixing part 530.

Illustratively, the positions of the infrared emitter 510 and the infrared receiver 520 on the fixing part 530 correspond to the liquid lens edge. It can be understood that the deformation degree of the liquid lens edge is larger than the deformation degree of the inner side wall (namely, the center of the liquid lens) far away from the clamp 500, so that when liquid leakage occurs, the liquid lens leakage can be quickly and accurately determined.

Illustratively, the driving unit 420 may be an electric driving unit, a mechanical driving unit, a manual driving unit, or the like.

For example, as shown in fig. 2, the driving unit 420 of the liquid state camera includes: the driving rod 423 is connected with the pressing member 421, and the support member 422 is disposed opposite to the pressing member 421. The supporting member 422, the liquid lens, and the pressing member 421 are sequentially disposed along the optical axis direction of the liquid lens. A drive rod 423 is provided on a side of the pressing member 421 remote from the liquid lens.

Illustratively, referring to fig. 2, there may be two drive rods 423 on each expression member 421.

Illustratively, as shown in fig. 3, the number of the pressing members 421 is two, and the two pressing members 421 are oppositely disposed, i.e., uniformly distributed along a circumference of the inner sidewall of the housing 400. In this manner, a uniform pressing force may be applied to the liquid lens by the pressing member 421 when the driving unit 420 operates.

It is understood that a drive rod 423 is connected to each pressing member 421, and each pressing member 421 corresponds to one support 422. The first distance is set between the extruding part 421 and the support part 422, the extruding part 421 can move under the condition that the driving rod 423 receives driving force, the support part 422 is kept fixed, and the distance of the first distance can be reduced or increased along with the movement of the extruding part 421 so as to adjust the focal length of the liquid lens.

Because when extrusion piece 421 extrudees liquid lens, be close to the deformation of the liquid lens membrane of extrusion piece 421, be less than the deformation of the liquid lens membrane of keeping away from extrusion piece 421, in order to detect real objective infrared parameter, in this application embodiment, infrared emitter 510 and infrared receiver 520 keep away from extrusion piece 421 and set up.

Illustratively, in the case where the liquid-state camera is clamped in the clamp 500, that is, in the case where the housing 400 of the liquid-state camera is clamped in the clamp 500 by the clamping portion, in the orthographic projection of the clamp 500 and the liquid-state camera, the infrared emitter 510 and the infrared receiver 520 are arranged offset from the pressing members 421, and the infrared emitter 510 and the infrared receiver 520 are arranged away from the pressing members 421, for example, in the orthographic projection, the infrared emitter 510 and the infrared receiver 520 are positioned at the center between two adjacent pressing members 421 and near the edge of the liquid-state lens.

Optionally, in this embodiment of the application, as shown in fig. 4, when the liquid-state camera is clamped in the clamp 500, the infrared emitter 510 and the infrared receiver 520 are respectively located at two sides of the liquid-state camera;

the second infrared signal is: and the first infrared signal is transmitted through the liquid lens.

For example, the liquid camera may be set at a preset position of the fixture 500, and the preset position may be a fixed position.

It is understood that the infrared transmitter 510 and the infrared receiver 520 are respectively fixed on the inner sidewall of the jig 500, that is, the positions of the infrared transmitter 510 and the infrared receiver 520 on the inner sidewall of the jig 500 are fixed. When the liquid camera is arranged in the clamp 500, under the condition that liquid does not leak, the distance a between the liquid camera and the infrared emitter 510 and the distance b between the liquid camera and the infrared receiver 520 are respectively the same; under the condition of liquid leakage, the thickness of the liquid lens changes, so that the distance a between the liquid lens and the infrared emitter 510 changes, and the distance b between the liquid lens and the infrared receiver 520 also changes, therefore, the first infrared signal emitted by the infrared emitter 510 and the second infrared signal transmitted by the liquid lens also correspondingly change, and further, the infrared parameter changes.

Therefore, whether the liquid lens leaks or not can be determined according to the infrared parameters detected by the liquid camera detection device.

Illustratively, referring to FIG. 4, an infrared transmitter 510 is positioned below the liquid lens and an infrared receiver 520 is positioned above the liquid lens.

Illustratively, the infrared emitter may also be located above the liquid lens, and the infrared receiver may also be located below the liquid lens.

Optionally, in this embodiment of the application, as shown in fig. 1, when the liquid camera is clamped in the clamp 500, the infrared transmitter 510 and the infrared receiver 520 are both disposed on the same side of the liquid lens;

the second infrared signal is: and the first infrared signal is a signal after being reflected by the liquid lens.

It is understood that the infrared transmitter 510 and the infrared receiver 520 are fixed to the inner sidewall of the jig 500, that is, the positions of the infrared transmitter 510 and the infrared receiver 520 on the inner sidewall of the jig 500 are fixed.

When the liquid camera is arranged in the clamp 500, under the condition that liquid does not leak, the distance a between the liquid camera and the infrared emitter 510 and the distance b between the liquid camera and the infrared receiver 520 are respectively the same; in the case of liquid leakage, the thickness of the liquid lens changes, so that the distance a between the liquid lens and the ir emitter 510 changes, and the distance b between the liquid lens and the ir receiver 520 also changes, and therefore, the first infrared signal emitted by the ir emitter 510 and the second infrared signal reflected by the liquid lens also change correspondingly, that is, the infrared parameter changes. Therefore, whether the liquid lens leaks or not can be determined according to the infrared parameters detected by the liquid camera detection device.

Or, when the liquid camera is disposed in the fixture 500, compared with when the liquid lens is not damaged, when the liquid lens is damaged, the curvature of the liquid lens film changes, the reflection and/or refraction angle of the first infrared signal emitted by the infrared emitter 510 on the liquid lens changes, and then the light intensity of the second infrared signal reflected by the infrared receiver 520 is received changes, that is, the infrared parameter changes. Therefore, whether the liquid lens leaks or not can be determined according to the infrared parameters detected by the liquid camera detection device.

Illustratively, as shown in fig. 5 and 6, since the liquid image pick-up head in fig. 6 leaks, it can be seen from fig. 5 and 6 that the curvature of the liquid lens film 411 in fig. 5 is different from that of the liquid lens film 411 in fig. 6. Therefore, the second infrared signal received by the infrared receiver 520 corresponding to fig. 5 is different from the second infrared signal received by the infrared receiver 520 corresponding to fig. 6, and the infrared parameter detected by the liquid camera detection device is different. It can be understood that the infrared parameters detected by the liquid camera detection device corresponding to fig. 5 may satisfy the corresponding first preset relationship; the infrared parameters detected by the liquid camera detection device corresponding to fig. 6 do not satisfy the corresponding preset relationship. Therefore, whether the liquid lens leaks or not can be quickly and accurately determined according to the infrared parameters detected by the liquid camera detection device.

Illustratively, as shown in fig. 1, infrared emitter 510 and infrared receiver 520 may both be disposed below the liquid lens.

Illustratively, the infrared emitter 510 and the infrared receiver 520 may be both disposed above the liquid lens.

An electronic device 200 is further provided in the embodiment of the present application, as shown in fig. 7, where the electronic device 200 includes the liquid camera detection apparatus 100 provided in any one of the embodiments.

The embodiment of the present application further provides an electronic device 300, as shown in fig. 8, the electronic device 300 includes a processing unit 302 and a power supply unit 301 connected to the processing unit.

In the scene of producing above-mentioned liquid camera, can be connected power supply unit and liquid camera detection device's power supply port electricity, can be to the drive unit of liquid camera, infrared emitter, the infrared receiver power supply, thereby, can detect the infrared parameter of liquid camera's liquid camera lens when non-deformation and deformation, and send the infrared parameter that detects to the processing unit, through the processing unit, compare received infrared parameter and the first relation of predetermineeing that corresponds, can accurately confirm whether weeping of liquid camera lens, thereby improve the quality control quality of liquid camera in the production stage, avoid regarding the liquid camera of damaged weeping as normal product, be used for other electronic equipment.

Specifically, the electronic device 300 may detect an infrared parameter when the liquid lens is not deformed through the infrared transmitter and the infrared receiver, and send the detected infrared parameter to the processing unit, the processing unit compares the received infrared parameter with the corresponding first preset relationship, and if the received infrared parameter meets the corresponding first preset relationship, it is determined that the liquid lens has not leaked; otherwise, leakage occurs.

The electronic device 300 may further detect an infrared parameter when the liquid lens deforms through the infrared transmitter and the infrared receiver, and send the detected infrared parameter to the processing unit, the processing unit compares the received infrared parameter with the corresponding first preset relationship, and if the received infrared parameter meets the corresponding first preset relationship, it is determined that the liquid lens does not leak; otherwise, leakage occurs.

Optionally, in this embodiment of the application, the electronic device 300 further includes a display unit 303; the display unit is used for displaying first prompt information or second prompt information, the first prompt information is used for prompting liquid lens liquid leakage, and the second prompt information is used for prompting that the liquid lens does not leak liquid.

Illustratively, the display unit may be electrically connected with the power supply unit through the processing unit, and the display unit is used for displaying a processing result of the processing unit.

As shown in fig. 9, an embodiment of the present application further provides a liquid camera leakage detection method, which can be applied to the liquid camera detection device provided in any of the above embodiments, and the method provided in the embodiment of the present application is described below with the liquid camera detection device as an execution main body. The method comprises step 101 and step 102.

Step 101, when the liquid camera is arranged in a fixture of the liquid camera detection device, and under the condition that a starting instruction of the liquid camera is detected, detecting a liquid lens of the liquid camera through an infrared emitter and an infrared receiver of the liquid camera detection device to obtain a first infrared parameter.

In this embodiment of the application, the start instruction may be: a shooting instruction, such as a photographing instruction or a video recording instruction.

102, displaying first prompt information under the condition that the first infrared parameter meets a first preset relation;

the step 101 of detecting the liquid lens of the liquid camera by the infrared emitter and the infrared receiver of the liquid camera detection device includes,

step 101a, the infrared emitter emits a first infrared signal.

And 101b, receiving a second infrared signal by the infrared receiver, wherein the second infrared signal is the first infrared signal after the first infrared signal is reflected or transmitted by the liquid lens.

Wherein the first infrared parameter is a first ratio of the first infrared signal to the second infrared signal;

the first prompt information is used for prompting liquid lens liquid leakage.

In the embodiment of the present application, the first predetermined relationship is: and presetting a numerical value corresponding to the infrared parameter when the liquid lens is not deformed.

In this embodiment of the application, under the condition that the above-mentioned start instruction is detected, the liquid camera may be in a state of not deforming. As shown in fig. 6, fig. 6 is a schematic diagram illustrating a state that the liquid camera is not deformed, in this case, power may be supplied to the infrared transmitter and the infrared receiver unit through a power supply unit of the external device, the infrared transmitter may supply a first infrared signal to the liquid lens, and the infrared receiver may receive a second infrared signal, so as to detect a first infrared parameter (for example, a first ratio between the first infrared signal and the second infrared signal, or an intensity value of the second infrared signal), and further, compare the first infrared parameter with a corresponding first preset relationship, and determine whether the first infrared parameter satisfies the first preset relationship.

In the embodiment of the application, the first prompt message can be displayed in a highlighted mode, so that the user can conveniently check the first prompt message.

Illustratively, the first prompt message includes at least one of: and identifying the prompt information by using the character prompt information. Taking the text prompt information as an example, the first prompt information may be: and (4) liquid leakage of the liquid camera.

Optionally, in this embodiment of the application, when the liquid-state camera is clamped in the fixture, the infrared emitter and the infrared receiver are respectively located at two sides of the liquid-state lens;

the second infrared signal is the first infrared signal after being transmitted by the liquid lens.

Optionally, in this embodiment of the application, when the liquid-state camera is clamped in the fixture, the infrared emitter and the infrared receiver are both disposed on the same side of the liquid-state lens;

the second infrared signal is the first infrared signal after being reflected by the liquid lens.

Optionally, in this embodiment of the present application, the method further includes steps 103 to 105.

103, controlling a driving unit of the liquid camera to drive the liquid lens to deform under the condition that the first infrared parameter does not meet a first preset relation;

104, detecting a liquid lens of the liquid camera through an infrared transmitter and an infrared receiver of the liquid camera detection device to obtain a second infrared parameter;

105, displaying second prompt information under the condition that the second infrared parameter meets the first preset relation;

wherein the second infrared parameter is: after the liquid camera is deformed, a first infrared signal transmitted by the infrared transmitter and a second infrared signal received by the infrared receiver are in a second proportion;

the second prompt information is used for prompting liquid lens liquid leakage.

It can be understood that after the driving unit controlling the liquid camera drives the liquid lens to deform, the above steps 101a and 101b may be repeated to obtain the second infrared parameter.

It can be understood that the liquid lens does not leak when not deformed, however, when deformed, the liquid lens film may be damaged by pressure during use, thereby leaking liquid. In order to ensure that the liquid lens is in a non-leakage state no matter the liquid lens is deformed or not deformed, whether the liquid lens leaks or not needs to be detected when the liquid lens is in the deformed state.

It should be noted that, the first predetermined relationship in the embodiment of the present application is: and presetting a numerical value corresponding to the infrared parameter when the liquid lens deforms.

In this embodiment, if the first infrared parameter satisfies the corresponding first predetermined relationship (i.e. the predetermined relationship of the numerical value corresponding to the infrared parameter when the liquid lens is not deformed), it indicates that the liquid lens does not leak when the liquid lens is in the non-deformed state. In this case, the liquid lens may be driven to deform by the driving unit.

After the liquid lens is deformed, the liquid lens can be continuously detected through the infrared emitter and the infrared receiver to obtain a second infrared parameter. If the second infrared parameter satisfies the corresponding first preset relationship (i.e. the preset relationship of the numerical value corresponding to the infrared parameter when the liquid lens is deformed), it is indicated that the liquid lens has no liquid leakage, and the liquid lens belongs to a good product (i.e. a normal product). And if the second infrared parameter does not meet the corresponding first preset relation, indicating that the liquid lens leaks, displaying second prompt information. The specific scheme of the second prompt message may refer to the first prompt message, and is not described herein again.

For example, referring to fig. 5 and 6, since the liquid image pick-up head of fig. 6 leaks, it can be seen from fig. 5 and 6 that the curvature of the liquid lens film 411 of fig. 5 is different from that of the liquid lens film 411 of fig. 6. Therefore, the second infrared parameter detected by the liquid camera detection device corresponding to fig. 5 is different from the second infrared parameter detected by the liquid camera detection device corresponding to fig. 6. It can be understood that the second infrared parameter detected by the liquid camera detection device corresponding to fig. 5 may satisfy the corresponding first preset relationship; the second infrared parameter detected by the liquid camera detection device corresponding to fig. 6 does not satisfy the corresponding first preset relationship.

Optionally, in an embodiment of the present application, the method further includes: and step 106.

106, displaying third prompt information under the condition that the second infrared parameter does not meet the first preset relation;

wherein the third prompt information is used for prompting the liquid camera

It can be understood that the first predetermined relationship in the embodiment of the present application is: and presetting a numerical value corresponding to the infrared parameter when the liquid lens deforms.

It should be noted that, if the first infrared parameter satisfies the corresponding first preset relationship, the third prompt information may also be displayed.

The specific scheme of the third prompt message may refer to the first prompt message, and is not described herein again.

It can be understood that if the second infrared parameter satisfies the corresponding first preset relationship, it indicates that the liquid lens has no liquid leakage, and the liquid camera belongs to a good product (i.e. a normal product), so that the third prompt information can be displayed to prompt a detector, and the detected liquid camera is a normal product.

Optionally, in this embodiment of the application, the liquid camera detection device includes an infrared detection unit, and the infrared detection unit includes the above-mentioned infrared emitter and infrared receiver. If the number of the infrared detection units is multiple, the first infrared parameter and the second infrared parameter are both: and detecting the average value of the infrared parameters obtained by the liquid camera through a plurality of infrared detection units.

Therefore, the influence on the detection result of the infrared detection unit caused by different damage positions is avoided. The accuracy of the detection result is improved.

Optionally, in this embodiment of the application, the step 103 of "controlling the driving unit of the liquid camera to drive the liquid lens to deform" includes a step 103 a.

And 103a, controlling a driving unit of the liquid camera to drive the liquid lens to generate a first deformation quantity.

The first deformation is greater than or equal to a first preset deformation and less than or equal to a second preset deformation. For example, the first deformation amount is a deformation amount corresponding to a focal length of the liquid lens reaching 2 times (or other focal lengths).

It should be noted that the second preset deformation amount is a deformation amount corresponding to the maximum deformation of the liquid lens, and the first preset deformation amount is a deformation amount corresponding to the minimum deformation of the liquid lens.

It is understood that the first predetermined amount of deformation is less than the second predetermined amount of deformation.

Illustratively, the first amount of deformation may be slightly less than the second predetermined amount of deformation. Therefore, the liquid lens leakage detection device can prevent the first deformation from being overlarge and causing loss to the liquid lens, and can detect whether the liquid lens leaks when working normally.

Optionally, in this embodiment of the application, before "detecting a liquid lens of the liquid camera by using an infrared emitter and an infrared receiver of the liquid camera detection device" in step 101, the method further includes:

and step A, determining whether the liquid lens deforms or not.

And B, if the deformation occurs, controlling the liquid lens to be in a non-deformation state.

And C, if the deformation does not occur, executing the step 101.

In the embodiment of the application, whether the liquid lens deforms or not is determined, and the determination can be performed through the focal length of the liquid lens.

In the embodiment of the application, the liquid lens is controlled to be in an undeformed state, that is, the liquid lens is controlled to be in an initial state.

For example, if the liquid lens is deformed, the liquid lens may be controlled to be in an undeformed state by a driving unit of the liquid camera.

According to the liquid camera leakage detection method provided by the embodiment of the application, when the liquid camera is arranged in a clamp of a liquid camera detection device, and a starting instruction of the liquid camera is detected, a liquid lens of the liquid camera is detected through an infrared emitter and an infrared receiver of the liquid camera detection device, and first prompt information is displayed when a first infrared parameter meets a first preset relation; the first prompt information is used for prompting the liquid lens to leak liquid. Therefore, whether the liquid lens of the liquid camera leaks or not can be conveniently confirmed by a user (namely, a detector) through the first prompt message, the accuracy of quality inspection of the liquid lens without leakage in the process of producing the liquid camera is improved, and the liquid camera is prevented from being used under the condition of liquid lens leakage and causing damage to the liquid camera and a corresponding circuit board.
