[0027] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0028] Before explaining in detail the control method of the IR-CUT switch provided in the embodiment of the present application, the shooting device involved in the embodiment of the present application is first introduced.

[0029] Please refer to Figure 1 , Figure 1 1 is a structural block diagram of a shooting device provided in an embodiment of the present application. The shooting device includes an IR-CUT switch 10, and the IR-CUT switch 10 includes a filter component 101 and a power component 102, wherein the power component is mechanically connected to the filter component, and the power component is used to drive the filter component 101 to move.

[0030] In some embodiments, please refer to Figure 2 The shooting device further includes an imaging element 20, and the filter assembly 101 is used to filter the light incident on the imaging element 20. For example, the filter assembly 101 includes two filters, namely, an infrared cutoff filter and a full-spectrum filter, and the infrared cutoff filter is located above the full-spectrum filter.

[0031] When there is sufficient light during the day, the power component 102 drives the filter component 101 to move to position 1, so that the infrared cutoff filter filters the light incident on the imaging element 20, thereby preventing infrared light from entering the imaging element 20 to ensure the true restoration of the image color; at night or when there is insufficient light, please refer to Figure 3 The power component 102 drives the filter component 101 to move to position 2, so that the infrared cutoff filter is removed, and the full-spectrum filter filters the light incident on the imaging element 20. In this case, the full-spectrum filter allows all light to enter the imaging element of the shooting device, thereby improving the sensitivity and clarity of the image.

[0032] For the sake of ease of description, when the infrared cutoff filter is used to filter the light incident to the imaging element, the position of the filter component is called the visible light shooting position; when the full spectrum filter is used to filter the light incident to the imaging element, the position of the filter component is called the infrared shooting position.

[0033] It should be noted that the above Figure 2 and Figure 3 The location of the mid-infrared cut-off filter above the fully transparent spectrum filter is merely an example. In some embodiments, the fully transparent spectrum filter may also be located above the infrared cut-off filter. Thus, under different lighting conditions, the position of the filter assembly driven by the power assembly also needs to be adaptively adjusted according to the positional relationship between the fully transparent spectrum filter and the infrared cut-off filter. For example, during the day when there is sufficient light, the power assembly drives the filter assembly to move to position 2, and at night or when there is insufficient light, the power assembly 102 drives the filter assembly 101 to move to position 1. This embodiment of the present application does not limit this. The imaging element may be a CCD (Charge-Coupled Device), a CMOS (Complementary Metal-Oxide-Semiconductor), etc. This embodiment of the present application does not limit this.

[0034] However, if the photographing device is accidentally dropped, the violent physical impact may cause the filter assembly to vibrate up and down or back and forth in the photographing device, thereby hitting other structures in the photographing device, affecting the normal operation of the IR-CUT switcher (for example, causing the filter in the filter assembly to be damaged, etc.). In addition, the collision between the filter assembly and other structures may also damage other key components in the photographing device (for example, the filter assembly hits the imaging element, causing damage to the imaging element, etc.), ultimately causing problems such as color distortion, reduced clarity or functional abnormalities in the captured image, thereby reducing the service life of the photographing device.

[0035] Based on this, the embodiment of the present application provides a control method for an IR-CUT switch, which can detect whether the shooting device is in a free fall state, and then control the filter component to be fixed in the first position through the power component when the shooting device is in a free fall state. In other words, the embodiment of the present application can fix the position of the filter component when the shooting device falls, thereby ensuring that the filter component will not vibrate in the shooting device due to the fall. In this way, it can effectively avoid the situation where the filter component hits other structures in the shooting device, causing damage to the IR-CUT switch and other components, thereby effectively improving the service life of the shooting device.

[0036] Those skilled in the art should understand that the functions of the above-mentioned shooting equipment are only examples, and other existing or future functions that may appear, if applicable to the embodiments of the present application, should also be included in the protection scope of the embodiments of the present application and are included here by reference.

[0037] It should be noted that the shooting equipment described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can know that with the evolution of technology, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0038] Next, the control method of the IR-CUT switch provided in the embodiment of the present application is explained in detail.

[0039] Figure 4 This is a flow chart of a control method of an IR-CUT switch provided in an embodiment of the present application. The method is applied to a shooting device, the shooting device includes an IR-CUT switch, the IR-CUT switch includes a filter component and a power component, the power component is mechanically connected to the filter component, and the power component is used to drive the filter component to move. Please refer to Figure 4 , the method comprises the following steps.

[0040] Step 401: Detect the motion state of the shooting device, where the motion state is used to indicate whether the shooting device is in a free fall state.

[0041] In some embodiments, the photographing device may periodically detect the motion state of the photographing device.

[0042] The detection period is set in advance, for example, the detection period may be 1 millisecond, and may be adjusted according to requirements in different situations.

[0043] In some embodiments, the camera device further includes an acceleration sensor, which is used to detect the acceleration of the camera device. In this case, the camera device can obtain the acceleration of the camera device detected by the acceleration sensor; based on the acceleration of the camera device, the motion state of the camera device is determined. Wherein, when the acceleration is 0, the motion state of the camera device indicates that the camera device is in a free fall state.

[0044] When the acceleration is not 0, the motion state of the photographing device indicates that the photographing device is not in a free fall state.

[0045] In some embodiments, the acceleration sensor can detect acceleration in the three directions of x-axis, y-axis and z-axis respectively. In this case, if the acceleration sensor detects that the acceleration in the three directions of x-axis, y-axis and z-axis are all 0, it is determined that the acceleration is 0, otherwise, it is determined that the acceleration is not 0.

[0046] In some embodiments, the acceleration sensor includes a mass block, and the acceleration sensor measures acceleration based on the displacement or deformation of the mass block inside the acceleration sensor when the mass block is subjected to acceleration. That is, when the acceleration sensor is subjected to external force, the mass block inside the acceleration sensor will also be subjected to the force, thereby generating displacement or deformation. Based on the displacement or deformation of the mass block, the acceleration can be obtained according to relevant algorithms.

[0047] If the camera is in a free fall state, the mass block inside the acceleration sensor will be in a weightless state, and the resultant force on the mass block is 0. In this case, the mass block does not produce displacement or deformation, and the acceleration value detected by the acceleration sensor is 0. Therefore, when the acceleration sensor detects that the acceleration is 0, the embodiment of the present application can determine that the camera is in a free fall state.

[0048] Detecting the motion state of the shooting device by using an acceleration sensor is only one implementation method. Of course, the motion state of the shooting device can also be determined by other methods, and the embodiments of the present application are not limited to this.

[0049] Step 402: If the motion state of the photographing device indicates that the photographing device is in a free fall state, the filter component is controlled to be fixed at the first position by the power component.

[0050] In some embodiments, the first position is any position to which the filter assembly can move. In this case, if the photographing device is in a free-fall state, the filter assembly can be fixed at the first position by a power assembly.

[0051] In the event that the photographing device falls, the position of the filter assembly is fixed to ensure that the filter assembly will not vibrate in the photographing device due to the fall. This can effectively prevent the filter assembly from hitting other structures in the photographing device, thereby causing damage to the IR-CUT switch and other components, thereby effectively extending the service life of the photographing device.

[0052] If the motion state of the photographing device indicates that the photographing device is not in a free fall state, the filter component is not controlled to be fixed at the first position by the power component.

[0053] If the photographing device is not in a free-falling state, it means that the photographing component has no risk of vibration and impact, so there is no need to fix the filter component in the first position.

[0054] In some embodiments, the power assembly includes a positioning structure, and the photographing device outputs a positioning control signal to the positioning structure so as to position the filter assembly at the first position through the positioning structure.

[0055] In some other embodiments, the IR-CUT switch further comprises a housing, and the first position refers to a position where the top or bottom of the filter assembly contacts the housing. In this case, the camera device continuously outputs a holding voltage to the power assembly so that the filter assembly is fixed in the first position.

[0056] In some embodiments, the power assembly includes a motor. In this case, the shooting device can continuously output a holding voltage to the motor so that the filter assembly is fixed in the first position.

[0057] The holding voltage includes a first holding voltage or a second holding voltage.

[0058] If the first position is the position where the top of the filter assembly contacts the housing, a first holding voltage is output to the power assembly so that the power assembly drives the top of the filter assembly to contact the housing; if the first position is the position where the bottom of the filter assembly contacts the housing, a second holding voltage is output to the power assembly so that the power assembly drives the bottom of the filter assembly to contact the housing.

[0059] For example, see Figure 5 , Figure 5 is a schematic diagram of a first position provided by an embodiment of the present application. The first position may refer to the bottom of the filter assembly being in contact with the housing. In this case, the shooting device may continuously output a first holding voltage to the motor so that the motor applies a force downward to the filter assembly. Since the bottom of the filter assembly is already in contact with the housing, the force applied by the motor can drive the bottom of the filter assembly to abut against the housing, thereby fixing the filter assembly in the first position.

[0060] For another example, please refer to Figure 6 , Figure 6 is a schematic diagram of the position of a filter component provided in an embodiment of the present application. The first position may be as follows Figure 6 In this case, the top of the filter assembly is in contact with the housing. At this time, the photographing device can continuously output the second holding voltage to the motor so that the motor applies an upward force to the filter assembly. Since the top of the filter assembly is already in contact with the housing, the force applied by the motor can drive the bottom of the filter assembly to abut against the housing, thereby fixing the filter assembly in the first position.

[0061] In some other embodiments, the IR-CUT switch further includes a housing, and the power assembly includes a positioning structure; if the first position is a position where the filter assembly contacts the housing, a holding voltage is continuously output to the power assembly so that the filter assembly is fixed at the first position. If the first position is not a position where the filter assembly contacts the housing, a positioning control signal is output to the positioning structure so that the filter assembly is positioned at the first position through the positioning structure.

[0062] Among them, the first holding voltage and the second holding voltage are pre-set and can be adjusted according to needs in different situations, and the embodiments of the present application do not limit this.

[0063] In some embodiments, the filter assembly further includes a housing and at least one filter, and the housing is used to mount the at least one filter. In this case, the first position is a position where the housing does not block the light incident on the imaging element, so that the housing can avoid blocking the light entering the imaging element, thereby causing a black shadow to appear on the captured image, affecting the user experience.

[0064] Optionally, at least one filter comprises an infrared cut-off filter and / or a full spectrum filter.

[0065] For example, the at least one filter includes an infrared cut-off filter and a full-spectrum transmittance filter, and the first position may be a visible light shooting position or an infrared shooting position.

[0066] In some embodiments, the photographing device further includes an imaging element, and the filter assembly is used to filter the light incident on the imaging element. When the filter assembly is in the first position, the deformation amount generated by each point in the filter assembly when subjected to force is less than the deformation threshold, and the deformation threshold is the distance between the plane where the imaging element is located and the plane where the filter assembly is located.

[0067] When the shooting device is in a free fall state, even if the position of the filter assembly is fixed, it can only ensure that the filter assembly will not hit other structures due to the up and down vibration caused by the free fall, but the filter assembly will still vibrate back and forth due to the severe physical impact (that is, it will deform when subjected to force). If the deformation of the filter assembly is greater than the distance between the plane where the imaging element is located and the plane where the filter assembly is located, the deformed filter assembly will hit the imaging element, thereby damaging the imaging element. Based on this, the embodiment of the present application can fix the filter assembly in the first position when the shooting device is in a free fall state. Because when the filter assembly is in the first position, the deformation generated by each point in the filter assembly when subjected to force is less than the distance between the plane where the imaging element is located and the plane where the filter assembly is located, so that it can effectively ensure that the deformed filter assembly will not hit the imaging element, thereby effectively extending the service life of the imaging element.

[0068] For example, taking the above Figure 5 For example, Figure 5 As shown, the IR-CUT switch also includes a housing, and the power assembly includes a spiral column and a support column. The filter assembly includes a shell, a first connecting part, and two second connecting parts, and the first connecting part and the two second connecting parts are both in a circular ring structure. The two corners on the left side of the shell are respectively connected to the second connecting parts, and the second connecting part is sleeved on the support column to support the two angles; the corner on the upper right side of the shell is connected to the first connecting part, and the first connecting part is sleeved on the spiral column to support the corner; the corner on the lower right side of the shell is not connected to the spiral column or the support column through any connecting part. The filter assembly is located at Figure 5 In the first position shown, the shell of the IR-CUT switch can support the corner of the lower right side of the shell, so that the four corners of the filter assembly are all supported, thereby ensuring that the deformation amount generated by each point in the filter assembly when subjected to force is smaller than the distance between the plane where the imaging element is located and the plane where the filter assembly is located.

[0069] Of course, the above Figure 5 It is only an illustration of the first position. In practical applications, if the four corners of the filter assembly are connected to the spiral column or the support column through the connecting portion, in this case, even if the filter assembly does not support the corner of the lower right side of the shell through the outer shell, it can ensure that the deformation amount generated by each point in the filter assembly when subjected to force is smaller than the distance between the plane where the imaging element is located and the plane where the filter assembly is located. At this time, the first position can be any position where the filter assembly can move.

[0070] In some embodiments, if the motion state of the shooting device indicates that the shooting device is in a free fall state, and the filter component is currently located at the second position, the filter component is controlled by the power component to move from the second position to the first position, and the filter component is controlled to be fixed at the first position; when the filter component is located at the second position, there is at least one point in the filter component that generates a deformation amount greater than a deformation threshold when subjected to force.

[0071] Since when the filter assembly is located at the second position, there is at least one point in the filter assembly whose deformation amount generated when subjected to force is greater than the deformation threshold, similarly to the above, when the shooting device is in a free fall state, the deformed filter assembly will hit the imaging element, thereby damaging the imaging element. Therefore, when the shooting device is in a free fall state and the filter assembly is currently located at the second position, the power assembly can control the filter assembly to move from the second position to the first position, thereby ensuring that the deformed filter assembly will not hit the imaging element, thereby effectively extending the service life of the imaging element.

[0072] For example, if the filter assembly includes an infrared cutoff filter and a fully transparent spectral filter, and above the fully transparent spectral filter, the first position is the above-mentioned visible light shooting position, and the second position can be the above-mentioned infrared shooting position.

[0073] For example, please refer to Figure 6 , the second position can be as follows Figure 6 The position shown, in this case, as Figure 6 As shown, the IR-CUT switch also includes a housing, a power assembly includes a spiral column and a support column, and a filter assembly includes a housing, a first connection portion, and two second connection portions, and the first connection portion and the two second connection portions are both in a circular ring structure. The two corners on the left side of the housing are respectively connected to the second connection portions, and the second connection portions are sleeved on the support column to support the two angles; the corner on the upper right side of the housing is connected to the first connection portion, and the first connection portion is sleeved on the spiral column to support the corner; the corner on the lower right side of the housing is not connected to the spiral column or the support column through any connection portion to support the corner, which results in that when the filter assembly is located as shown in FIG. Figure 6 In the second position shown, there is at least one point in the housing (i.e., the corner on the lower right side of the filter assembly) whose deformation amount generated when subjected to force is greater than the deformation threshold. In this case, if the photographing device is in a free fall state, the filter assembly can be moved from the second position to the first position, and the filter assembly can be controlled to be fixed in the first position, so that the housing can support the corner on the lower right side of the housing, thereby ensuring that the deformation amount generated when subjected to force at each point in the filter assembly is less than the distance between the plane where the imaging element is located and the plane where the filter assembly is located.

[0074] If the motion state of the photographing device indicates that the photographing device is in a free-fall state, and the filter component is currently located at the first position, the filter component can be directly controlled to be fixed at the first position.

[0075] In some embodiments, after the filter assembly is fixed at the first position by the power assembly, the photographing device can also control the filter assembly to reset from the first position to the position before free fall by the power assembly when the photographing device meets the position reset condition.

[0076] Since the embodiment of the present application protects the photographing device by adjusting the filter component from the second position to the first position when the photographing device is in a free fall state, the movement of the filter component will change the light incident on the imaging element, thus changing the imaging quality and causing the user to perceive the change in the position of the filter component. Therefore, in the embodiment of the present application, when the photographing device meets the position reset condition, the power component controls the filter component to reset from the first position to the position before the free fall, so as to prevent the user from perceiving the change in the position of the filter component.

[0077] In some embodiments, the position reset condition includes at least one of the following: the motion state of the shooting device indicates that the shooting device is not in a free fall state; the time difference between the moment when the filter component is fixed in the first position and the current moment is equal to the time difference threshold.

[0078] If the position reset condition includes that the motion state of the shooting device indicates that the shooting device is not in a free fall state, then after the shooting device controls the filter component to be fixed in the first position through the power component, it can also periodically detect the motion state of the shooting device to determine whether the shooting device is not in a free fall state.

[0079] The time difference threshold is positively correlated with the upper limit of the free fall height. The higher the upper limit of the height, the larger the time difference threshold. For example, the time difference threshold may be 800 milliseconds. In this case, the embodiment of the present application can ensure the safety of the shooting device falling within a height of 3 meters. It can also be adjusted according to different height requirements in different situations.

[0080] Next, it will be passed Figure 7 The control method of the IR-CUT switch provided in the embodiment of the present application is introduced again.

[0081] Please refer to Figure 7, the IR-CUT switch 10 includes a filter assembly 101 and a power assembly 102, the power assembly is used to drive the filter assembly to move, and the shooting device also includes an imaging element 20, and the filter assembly is used to filter the light incident on the imaging element. The filter assembly 101 includes two filters, namely an infrared cut-off filter and a full-spectrum filter, the infrared cut-off filter is located above the full-spectrum filter, and the first position is the visible light shooting position. In this case, the acceleration of the shooting device detected by the acceleration sensor is obtained. If the acceleration sensor detects that the accelerations in the three directions of the x-axis, the y-axis and the z-axis are all 0, it is determined that the motion state of the shooting device indicates that the shooting device is in a free fall state. At this time, if the filter assembly is located at the infrared shooting position, the filter assembly is controlled by the power assembly to move from the infrared shooting position to the visible light shooting position, and the filter assembly is controlled to be fixed at the visible light shooting position. If the time difference between the moment when the filter assembly is fixed at the first position and the current moment is equal to 800 milliseconds, the filter assembly is controlled by the power assembly to reset from the first position to the position before the free fall. If the filter assembly is located at the visible light shooting position, the power assembly controls the filter assembly to be fixed at the visible light shooting position. If the time difference between the moment when the filter assembly is fixed at the first position and the current moment is equal to 800 milliseconds, the position of the filter assembly is canceled.

[0082] In the embodiment of the present application, the position of the filter assembly is fixed when the shooting device falls, thereby ensuring that the filter assembly will not vibrate in the shooting device due to the fall. In this way, it is possible to effectively avoid the filter assembly colliding with other structures in the shooting device, thereby causing damage to the IR-CUT switch and other components, thereby effectively improving the service life of the shooting device. In the case where the filter assembly also includes a housing and at least one filter, and the housing is used to install the at least one filter, the first position is a position where the housing does not block the light incident on the imaging element. In this way, it is possible to avoid the housing blocking the light entering the imaging element, thereby causing a black shadow to appear on the captured image, affecting the user experience.

[0083] The embodiment of the present application can also fix the filter assembly at the first position when the shooting device is in a free fall state. Since when the filter assembly is in the first position, the deformation amount generated by each point in the filter assembly when subjected to force is smaller than the distance between the plane where the imaging element is located and the plane where the filter assembly is located, it can effectively ensure that the deformed filter assembly will not hit the imaging element, thereby effectively extending the service life of the imaging element. Since when the filter assembly is in the second position, there is at least one point in the filter assembly whose deformation amount generated when subjected to force is greater than the deformation threshold, when the shooting device is in a free fall state, the deformed filter assembly will hit the imaging element, thereby damaging the imaging element. Therefore, when the shooting device is in a free fall state and the filter assembly is currently in the second position, the power assembly can control the filter assembly to move from the second position to the first position, thereby ensuring that the deformed filter assembly will not hit the imaging element, thereby effectively extending the service life of the imaging element.

[0084] Since the embodiment of the present application protects the photographing device by adjusting the filter component from the second position to the first position when the photographing device is in a free fall state, the movement of the filter component will change the light incident on the imaging element, thus changing the imaging quality and causing the user to perceive the change in the position of the filter component. Therefore, in the embodiment of the present application, when the photographing device meets the position reset condition, the power component controls the filter component to reset from the first position to the position before the free fall, so as to prevent the user from perceiving the change in the position of the filter component.

[0085] The embodiment of the present application also provides a shooting device, which includes an IR-CUT switch and a control device, the IR-CUT switch includes a filter assembly and a power assembly, the power assembly is mechanically connected to the filter assembly, the power assembly is used to drive the filter assembly to move, the control device is communicatively connected to the power assembly, and the control device is configured to: detect the motion state of the shooting device, the motion state is used to indicate whether the shooting device is in a free fall state. If the motion state indicates that the shooting device is in a free fall state, the filter assembly is controlled by the power assembly to be fixed in the first position.

[0086] It should be noted that the actions performed by the control device provided in the above embodiment belong to the same concept as the control method embodiment of the above IR-CUT switch. The specific implementation process is detailed in the method embodiment and will not be repeated here.

[0087] The embodiment of the present application also provides a control device for an IR-CUT switcher, which is applied to a photographing device. The device includes: a detection module and a control module.

[0088] The detection module is used to detect the motion state of the shooting device, and the motion state is used to indicate whether the shooting device is in a free fall state. The detailed implementation process refers to the corresponding content in the above embodiments, which will not be repeated here.

[0089] The control module is used to control the filter component to be fixed at the first position through the power component if the motion state indicates that the shooting device is in a free fall state. The detailed implementation process refers to the corresponding content in the above embodiments, which will not be repeated here.

[0090] In some embodiments, the photographing device further includes an imaging element, and the filter component is used to filter the light incident on the imaging element;

[0091] When the filter assembly is located at the first position, the deformation amount generated by each point in the filter assembly when subjected to force is smaller than the deformation threshold; wherein the deformation threshold is the distance between the plane where the imaging element is located and the plane where the filter assembly is located.

[0092] In some embodiments, the IR-CUT switch further includes a housing, the first position refers to a position where the top or bottom of the filter assembly contacts the housing; and the control module is specifically configured to:

[0093] If the first position is a position where the top of the filter assembly contacts the housing, outputting a first holding voltage to the power assembly so that the power assembly drives the top of the filter assembly to contact the housing;

[0094] If the first position is the position where the bottom of the filter assembly contacts the housing, a second holding voltage is output to the power assembly so that the power assembly drives the bottom of the filter assembly to contact the housing.

[0095] In some embodiments, the power assembly further includes a positioning structure; the control module is specifically used for:

[0096] A positioning control signal is output to the positioning structure so as to position the filter assembly at a first position through the positioning structure.

[0097] In some embodiments, the control module is specifically configured to:

[0098] If the motion state indicates that the photographing device is in a free-fall state, and the filter assembly is currently located at the second position, the filter assembly is controlled by the power assembly to move from the second position to the first position, and the filter assembly is controlled to be fixed at the first position;

[0099] When the filter assembly is located at the second position, there is at least one point in the filter assembly whose deformation amount generated when subjected to force is greater than the deformation threshold.

[0100] In some embodiments, the apparatus further comprises:

[0101] The reset module is used to control the filter component to reset from the first position to the position before free fall through the power component when the shooting device meets the position reset condition.

[0102] In some embodiments, the position reset condition includes at least one of the following:

[0103] The motion state of the camera device indicates that the camera device is not in a free fall state;

[0104] The time difference between the moment when the filter component is fixed at the first position and the current moment is equal to the time difference threshold.

[0105] In some embodiments, the photographing device further includes an acceleration sensor, and the acceleration sensor is used to detect the acceleration of the photographing device;

[0106] The detection module is specifically used for:

[0107] Get the acceleration of the camera detected by the acceleration sensor;

[0108] Based on the acceleration of the shooting device, the motion state of the shooting device is determined; wherein, when the acceleration is 0, the motion state indicates that the shooting device is in a free fall state.

[0109] In the embodiment of the present application, the position of the filter assembly is fixed in the case where the shooting device falls, so as to ensure that the filter assembly will not vibrate in the shooting device due to the fall. In this way, it is possible to effectively avoid the situation where the filter assembly hits other structures in the shooting device, causing damage to the IR-CUT switch and other components, thereby effectively improving the service life of the shooting device. In the case where the filter assembly also includes a housing and at least one filter, and the housing is used to install the at least one filter, the first position is a position where the housing does not block the light incident on the imaging element. In this way, it is possible to avoid the housing blocking the light entering the imaging element, so that a black shadow appears in the shooting picture, affecting the user's experience. In the embodiment of the present application, the filter assembly can also be fixed in the first position when the shooting device is in a free fall state. Since when the filter assembly is in the first position, the deformation amount generated by each point in the filter assembly when subjected to force is less than the distance between the plane where the imaging element is located and the plane where the filter assembly is located, it is possible to effectively ensure that the deformed filter assembly will not hit the imaging element, thereby effectively extending the service life of the imaging element. Since when the filter assembly is in the second position, there is at least one point in the filter assembly whose deformation amount generated when subjected to force is greater than the deformation threshold, when the shooting device is in a free fall state, the deformed filter assembly will hit the imaging element, thereby damaging the imaging element. Therefore, when the shooting device is in a free fall state and the filter assembly is currently in the second position, the shooting device can control the filter assembly to move from the second position to the first position through the power assembly, thereby ensuring that the deformed filter assembly will not hit the imaging element, thereby effectively extending the service life of the imaging element. Since the embodiment of the present application protects the shooting device by adjusting the filter assembly from the second position to the first position when the shooting device is in a free fall state, the movement of the filter assembly will change the light incident on the imaging element, thus changing the imaging quality and causing the user to perceive the change in the position of the filter assembly. Therefore, when the shooting device meets the position reset condition, the embodiment of the present application controls the filter assembly to reset from the first position to the position before the free fall through the power assembly, so as to avoid the user from perceiving the change in the position of the filter assembly.
