Description

Photographing device and system, lens parameter adjustment device, control method and device of light adjustment assembly, and medium TECHNICAL FIELD

[0001] The present specification relates to the field of optical technology, and in particular to a photographing device and system, a lens parameter adjustment device, a control method and device of a light adjustment assembly, and a medium. BACKGROUND

[0002] A photographing device can be used to take a still photo or a dynamic video. The photographing effect of the photographing device is affected by a light signal. When photographing, a light adjustment assembly can be arranged at the front end of the lens of the photographing device, so as to achieve adjustment of the light signal, thereby obtaining a specific photographing effect. As an important function of the photographing device, the adjustment function of the light signal needs to be further improved and promoted.

[0003] SUMMARY

[0004] In a first aspect, the present disclosure provides a photographing device, comprising: a body; a lens arranged on the body; a light adjustment assembly located at the front end of the lens, the light adjustment assembly having adjustable light adjustment parameters; and a cooperating piece, which is a component element of a physical control, the cooperating piece being electrically connected with the light adjustment assembly and arranged on the body or the light adjustment assembly, wherein the cooperating piece is used to cooperate with an adjustment piece of the physical control, so that the physical control is operated to generate a trigger signal, and the trigger signal is used to adjust the light adjustment parameters of the light adjustment assembly.

[0005] In the present disclosure, the light adjustment assembly with adjustable light adjustment parameters is arranged in the photographing device 10, and the cooperating piece arranged on the body of the photographing device or the light adjustment assembly is matched. By means of the trigger signal generated by the cooperating piece and the adjustment piece of the physical control, different light adjustment parameters can be obtained by using a single light adjustment assembly, without relying on the screen to input the control information of the light adjustment assembly. This is more friendly to the photographing device with a small display unit, and different light adjustment parameters can be obtained without replacing different light adjustment assemblies. At the same time, since the cooperating piece is electrically connected with the light adjustment assembly and arranged on the body or the light adjustment assembly, it is convenient for users to operate, and the convenience of the light adjustment process can be greatly improved. Furthermore, since the adjustment piece is only operated to change the light adjustment parameters, different light adjustment assemblies do not need to be disassembled or replaced, and the lens is not polluted when different light adjustment assemblies are replaced.

[0006] Secondly, this disclosure provides a shooting device, the shooting device comprising: a camera body; a lens disposed on the camera body; an electronic light adjustment component located at the front end of the lens, the dimming parameters of the electronic light adjustment component being adjustable; and a physical control disposed around the electronic light adjustment component and electrically connected to the electronic light adjustment component, wherein the physical control includes an adjustment element and a plurality of contacts, the contacts being disposed on the electronic light adjustment component, the adjustment element being sleeved around the contacts, and used to cooperate with the plurality of contacts to perform voltage selection to adjust the dimming parameters of the electronic light adjustment component.

[0007] This embodiment of the disclosure, by employing an adjustable electronic light adjustment component, achieves stepless or near-stepless adjustment. By placing physical controls on the periphery of the electronic light adjustment component, and through the cooperation of the adjustment element and contacts, users can conveniently adjust the dimming parameters of the electronic light adjustment component by operating the adjustment element, without relying on a screen to input control information for the light adjustment component. This is particularly beneficial for shooting devices with small display units. Furthermore, it eliminates the need to replace light adjustment components with different parameters or specifications to obtain different dimming parameters, and avoids lens contamination when replacing different light adjustment components.

[0009] This embodiment of the disclosure provides an electronic light adjustment component at the front of the lens. This component not only adjusts the light signal but also protects the lens. This allows for the reuse of a single component to achieve multiple functions, eliminating the need for an additional protective cap and reducing hardware costs. Furthermore, since the dimming parameters of the electronic light adjustment component are adjustable, a single component can be used to obtain various dimming parameters without requiring the replacement of components with different parameters or specifications. This avoids the problem of the lens not being protected when replacing components with different parameters or specifications.

Furthermore, physical controls are provided to adjust the dimming parameters of the electronic light adjustment component. This eliminates the need for inputting control information via a screen, making it more user-friendly for shooting devices with smaller display units. It allows for convenient and quick adjustment of the dimming parameters, enabling the use of a single electronic light adjustment component to obtain multiple different dimming parameters. This achieves stepless or near-stepless adjustment without requiring the replacement of light adjustment components with different parameters or specifications. This avoids the problem of lens unprotection when changing light adjustment components with different parameters or specifications, and improves the convenience of the dimming process.

After the light adjustment component is installed on the front of the lens, the light adjustment parameters can be adjusted simply by operating the physical control, eliminating the need for inputting control information for the light adjustment component via a screen. This is particularly beneficial for shooting devices with small display units. Furthermore, it allows for obtaining multiple different light adjustment parameters using a single light adjustment component, eliminating the need to replace light adjustment components with different parameters or specifications.

[0015] This embodiment of the disclosure generates a trigger signal by operating physical controls, and adjusts the dimming parameters of the light adjustment component through the trigger signal. This allows users to conveniently and quickly adjust the dimming parameters of the light adjustment component by operating physical controls, without relying on the screen to input control information for the light adjustment component. This is particularly user-friendly for shooting devices with small display units.

[0017] This embodiment of the disclosure generates a trigger signal by operating physical controls. In response to the trigger signal, the electrical control parameters of the electronic light adjustment component are adjusted. The current dimming parameters are determined based on the correlation between the electrical control parameters and the dimming parameters. This allows users to conveniently and quickly adjust the dimming parameters of the light adjustment component by operating the physical controls, eliminating the need for inputting control information through a screen. This is particularly beneficial for shooting devices with small display units. Furthermore, the current dimming parameters are sent to the display unit of the shooting device for display, allowing users to intuitively observe the currently used dimming parameters on the display unit, avoiding blind adjustment and improving the convenience of the dimming process. In addition, the light signal can achieve stepless or quasi-stepless adjustment with high adjustment precision.

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0042] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0043] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0044] The shooting device may include a lens that can receive light signals, and the shooting device can capture still photos or videos based on these light signals. During shooting, a light adjustment component can be installed at the front of the lens of the shooting device to adjust the light signal and obtain specific shooting effects. In related technologies, the dimming parameters of the light adjustment component are usually fixed. When different dimming parameters are needed to achieve different shooting effects, the light adjustment component needs to be replaced. This replacement operation is time-consuming and laborious. Furthermore, during the replacement of the light adjustment component, the lens may be touched, or dust may enter the space where the lens is located due to gaps, causing lens contamination and affecting the shooting effect. Based on this, this disclosure provides a shooting device 10. Referring to Figures 1 and 2, the shooting device 10 includes:

[0045] fuselage 101;

[0046] Lens 102 is mounted on camera body 101;

[0047] Light adjustment component 103 is located at the front end of lens 102, and the dimming parameters of light adjustment component 103 are adjustable; and

[0048] The mating component 104 is a component of the physical control 20. The mating component 20 is electrically connected to the light adjustment assembly 103 and is disposed on the body 101 or on the light adjustment assembly 103.

[0049] The mating part 104 is used to cooperate with the adjustment part 201 of the physical control 20 so that the physical control 20 is operated to generate a trigger signal, which is used to adjust the dimming parameters of the light adjustment component 103.

[0050] This embodiment of the present disclosure provides an adjustable light adjustment component 103 in the shooting device 10, which, together with a mating component 104 mounted on the camera body or the light adjustment component, can achieve multiple different light adjustment parameters using a single light adjustment component 103 by means of a trigger signal generated jointly by the mating component 104 and the adjustment component 201 of the physical control 20. This eliminates the need for inputting control information for the light adjustment component via a screen, making it more user-friendly for shooting devices with smaller display units, as it eliminates the need to replace different light adjustment components to obtain different light adjustment parameters. Furthermore, since the mating component 104 is electrically connected to the light adjustment component 103, it can convert the input information from the physical control into control information for the light adjustment component. The mating component 104 can be mounted on the camera body or the light adjustment component 103, facilitating user operation and greatly improving the convenience of the light adjustment process. Moreover, since the light adjustment parameters can be changed simply by manipulating the adjustment component 201, there is no need to disassemble or replace light adjustment components with different parameters or specifications, avoiding lens contamination when replacing different light adjustment components.

[0051] In this embodiment of the disclosure, the shooting device 10 can use an optical lens to frame the image, thereby achieving image or video capture. The shooting device 10 can be a camera, smartphone, tablet computer, camera pen, endoscope, or other similar device. When the shooting device 10 is a camera, the camera can be, but is not limited to, action cameras, panoramic cameras, SLR cameras, gimbal cameras, and other similar types.

[0052] The shooting device 10 may include a body 101 for accommodating the various components of the shooting device 10. The shooting device 10 also includes a lens 102, which may be mounted on the body 101. For example, the lens 102 may be fixedly connected to the body 101 via a lens mount, or detachably connected to the body 101. The lens 102 may be, but is not limited to, a telephoto lens, a zoom lens, a wide-angle lens, a fisheye lens, a macro lens, etc. In some embodiments, the shooting device 10 may also include an image sensor and an image processor (not shown). The lens 102 can sense and focus light signals onto the sensor surface. The image sensor can convert the light signals into electrical signals and send them to the image processor. The image processor can perform image processing (e.g., white balance processing, noise reduction processing, sharpening processing, etc.) based on the received electrical signals to obtain an output image.

[0053] The imaging device 10 also includes a light adjustment assembly 103, which is located at the front end of the lens 102. For example, the light adjustment assembly 103 may be fixedly connected to the front end of the lens 102 or detachably connected to the front end of the lens 102. In some embodiments, the light adjustment assembly 103 is located at the outermost edge of the lens 102. The shape of the light adjustment assembly 103 may match the shape of the lens 102 or the shape of the sensor. For example, when matching the shape of the lens, the light adjustment assembly 103 may be circular. Since the field of view (FOV) of the lens is conical, a circular light adjustment assembly 103 can better match the lens shape, thereby maximizing the transmission of light into the lens. In other embodiments, the light adjustment component 103 may be non-circular, for example, a rectangular light adjustment component. Preferably, when the sensor is a rectangular sensor, the shape of the light adjustment component is an inscribed rectangle of a circular lens. In this case, the diagonal of the rectangle is equal to the diameter of the lens's field of view (FOV), which allows the light adjustment component to be presented to the user in a smaller size while maximizing the use of the lens's FOV. Most preferably, when the sensor is square, the shape of the light adjustment component 103 is an inscribed square of a circular lens, which maximizes the use of the sensor's size while simultaneously matching the lens and the sensor, thus accommodating larger sensors. However, this disclosure is not limited to this. For example, the light adjustment component 103 and the lens 102 can be connected by a connector, where the shape of one end of the connector connecting to the light adjustment component 103 matches the shape of the light adjustment component 103, and the shape of one end of the connector connecting to the lens 102 matches the shape of the lens 102.

[0054] The light adjustment component 103 is used to adjust the light signal entering the lens 102. For example, the light adjustment component 103 can realize the light reduction value adjustment function, which can extend the exposure time. In the case of an overly bright scene, the neutral density filter can reduce the amount of light, helping the user to extend the exposure time to achieve the desired result. This is very useful for shooting flowing water, blurred motion effects, or long exposure photos taken at sunset or sunrise, allowing photographers to use a larger aperture in these situations without overexposure. Furthermore, by adjusting the light reduction value, the ISO can also be controlled to achieve specific visual effects. For example, when shooting video, by reducing the amount of light, a larger shutter speed can be used, thereby achieving the aforementioned blurred or smooth motion effects in the video. In some embodiments, in video shooting, using a neutral density filter with an adjustable light reduction value can adjust the light reduction level while keeping the shutter speed and aperture constant to obtain the desired degree of bokeh, achieving a realistic motion blur effect. In landscape photography, by reducing the shutter speed with a neutral density filter with an adjustable light reduction value, silky water surfaces and dynamic clouds can be obtained, freezing the changes over a period of time into a single image. In time-lapse photography, adjustable neutral density (ND) filters are used to reduce shutter speed, sometimes even to less than half the frame rate, to achieve more dynamic visuals and a stronger visual impact. In summary, because ND filters significantly reduce the amount of light entering the lens, using them allows users greater creative freedom and more diverse visual effects under various lighting conditions. For example, the light adjustment component 103 can achieve soft light adjustment, softening the image by blurring light, resulting in a softer, more natural picture. It can also achieve UV (ultraviolet absorption) value adjustment, reducing ultraviolet light transmittance without affecting visible light. Furthermore, it can achieve gradient color adjustment, creating specific color gradient effects in the image. Finally, it can achieve color filter adjustment, altering the color temperature of light or enhancing color effects, such as strengthening warm or cool tones, and achieving specific color effects. The light adjustment component 103 can also perform other light signal adjustment functions, or perform multiple functions at the same time, which will not be listed here.

[0055] In some embodiments, the light adjustment component 103 may be an electronic light adjustment component, such as an electronic ND (Neutral, Density) filter. Further, the electronic light adjustment component may be an electronic filter. An electronic filter is a filter implemented using liquid crystal display technology. Electronic filters change their optical properties through internal circuitry and a control system, offering high flexibility and functionality. Compared to traditional filters, electronic filters typically provide a wider adjustment range and greater precision. In some embodiments, the electronic filter may be a monolithic filter. A monolithic filter is a single optical element that integrates filter functions. Compared to filters using two polarizers in related solutions, the monolithic filter of this embodiment avoids the vignetting problem associated with multi-lens combinations. Furthermore, in some embodiments, a monolithic electronic filter can integrate multiple filter effects or characteristics onto a single optical glass or plastic sheet, instead of using multiple independent filter components. By employing a monolithic filter, the thickness of the electronic filter can be effectively reduced, thereby reducing the size of the imaging device 10, and also reducing the risk of introducing additional optical distortion or reducing image sharpness due to the use of multiple filters. Furthermore, because the adjustment of dimming parameters is done using a single-piece electronic filter, it is very inconvenient to input parameters via software adjustment for small-screen action cameras. Therefore, hardware adjustment is used to input the degree of adjustment. However, with hardware adjustment, users may not be able to intuitively feel the degree of adjustment of the electronic filter or the specific value of the dimming parameter. Thus, it is necessary to consider displaying the dimming parameter on the small screen simultaneously. The setting of using a mating component electrically connected to the light adjustment assembly can synchronize the dimming parameter to be displayed on the small screen, thus avoiding blind adjustment.

[0056] When the light adjustment component 103 is used to implement the light reduction value adjustment function, the light adjustment component 103 can be a light reduction filter; when the light adjustment component 103 is used to implement the soft light adjustment function, the light adjustment component 103 can be a soft light filter; when the light adjustment component 103 is used to implement the UV value adjustment function, the light adjustment component 103 can be a UV filter; when the light adjustment component 103 is used to implement the gradient color adjustment function, the light adjustment component 103 can be a gradient color filter; when the light adjustment component 103 is used to implement the color filter adjustment function, the light adjustment component 103 can be a color filter.

[0057] The dimming parameters of the light adjustment component 103 are adjustable. Specifically, the user can manually adjust the dimming parameters of the light adjustment component 103, or the dimming parameters can be automatically adjusted by recognizing factors such as environmental information, shooting scene information, or subject information. By using a light adjustment component 103 with adjustable dimming parameters, multiple different dimming parameters can be obtained using a single light adjustment component 103. When the dimming parameters need to be adjusted, there is no need to replace the light adjustment component 103, improving the convenience of the dimming process. In addition, the light adjustment component 103 is located at the front of the lens 102, which can provide a certain degree of isolation and protection for the lens 102. Furthermore, it can reduce the light before it is imaged by the lens, avoiding the problem that the closer the light adjustment component is to the sensor, the more easily the sensor will amplify abnormalities. Moreover, in some solutions, when the light adjustment component needs to be replaced, for example, a fixed-magnification ND filter is used to achieve different dimming parameters, the ND filter is removed, and the lens 102 loses its isolation and protection, making it susceptible to contamination by dust, water, and other pollutants. The use of an adjustable light adjustment component 103 eliminates the need to replace the light adjustment component 103, thereby reducing the risk of the lens 102 losing its protective isolation and becoming contaminated when replacing the ND filter.

[0058] In some embodiments, the lens 102 is hermetically connected to the light adjustment component 103. This provides a better waterproof and dustproof effect. In related technologies, the dimming parameters of ND filters are usually fixed. Therefore, different ND filters need to be replaced in different application scenarios, making a hermetically connected connection between the lens 102 and the ND filter unsuitable. However, in this embodiment, the dimming parameters of the light adjustment component 103 are adjustable. Therefore, it is not necessary to replace the light adjustment component 103 in different application scenarios, allowing the lens 102 and the light adjustment component 103 to be designed as a hermetically connected unit. This allows a single light adjustment component 103 to be suitable for various application scenarios while also achieving a waterproof and dustproof effect.

[0059] The dimming parameters of the light adjustment component 103 can be adjusted via a physical control 20. The physical control 20 includes a mating component 104 and an adjusting component 201, with the mating component 20 electrically connected to the light adjustment component 103. The mating component 104 can be mounted on the light adjustment component 103 (as shown in Figure 1), or it can be a component of the shooting device 10 and mounted on the body 101 of the shooting device 10 (as shown in Figure 2). The adjusting component 201 can be another component of the shooting device 10, or it can be a component outside the shooting device 10. This embodiment uses a physical control 20 to adjust the dimming parameters of the light adjustment component 103 (referred to as hardware adjustment or structural switching method). In contrast, a software method is used to adjust the dimming parameters of the light adjustment component 103 (referred to as software adjustment method). In the software adjustment method, the user needs to first access the parameter adjustment interface through the screen of the shooting device 10, and then trigger the parameter adjustment function within the parameter adjustment interface. This process is cumbersome, cannot achieve real-time parameter adjustment, and does not conform to the operating habits of handheld products. Furthermore, some shooting devices 10 (such as action cameras) have relatively small screens, making them inconvenient to observe and operate. The hardware adjustment method of this disclosure embodiment only requires the user to operate the physical control 20 to adjust the dimming parameters, which is simple and efficient. Moreover, because it enables real-time parameter adjustment and is not limited by the screen size of the shooting device 10, it improves the convenience of operation.

[0060] In some embodiments, the number of physical controls 20 may be greater than or equal to one. In embodiments where the number of physical controls 20 is one, different adjustment functions for the dimming parameters can be triggered by the same physical control 20. For example, at least two functions, such as increasing the dimming parameter, decreasing the dimming parameter, or changing the type of the currently adjusted dimming parameter, can be implemented by using different triggering methods on the same physical control 20. In this way, the additional physical control settings on the shooting device can be reduced, and the simplicity of the shooting device can be improved.

[0061] In embodiments where the number of physical controls 20 is greater than one, different physical controls can be used to trigger different adjustment functions for the dimming parameters. For example, one physical control 20 can be used to increase the dimming parameter, and another physical control can be used to decrease the dimming parameter; or, different physical controls 20 can be used to adjust different types of dimming parameters; or, different physical controls 20 can be used to adjust the dimming parameter to different parameter values. In this way, the operational difficulty of the shooting device can be reduced, and the user's learning cost can be lowered.

[0062] In some embodiments, the physical control 20 can not only adjust the dimming parameters, but also perform other shooting control functions, such as image capture or video recording. In other words, the same physical control 20 can be reused to implement multiple different functions, thereby reducing the number of hardware components and the size of the shooting device 10, and lowering hardware costs.

[0063] The physical control 20 can be operated by the mating component 104 in conjunction with the adjusting component 201 to generate a trigger signal for adjusting the dimming parameters of the light adjustment component 103. The trigger signal can be a continuous signal or a discrete signal. When the trigger signal is continuous, it can trigger continuous changes in the dimming parameters, resulting in a more precise and smooth adjustment. When the trigger signal is discrete, it can trigger abrupt changes in the dimming parameters, thereby simplifying the parameter adjustment system and saving resource consumption during the parameter adjustment process. The trigger signal includes, but is not limited to, at least one of the following: current signal, voltage signal, magnetic field signal, capacitance signal, resistance signal, force signal, and light signal.

[0064] In some embodiments, the adjusting member 201 can move relative to the mating member 104 to generate a trigger signal. For example, the mating member 104 can be fixed and the adjusting member 201 can be controlled to move; or, the adjusting member 201 can be fixed and the mating member 104 can be controlled to move; or, the adjusting member 201 and the mating member 104 can be controlled to move simultaneously. The above-mentioned movement can be linear or arcuate. The adjusting member 201 can be moved relative to the mating member 104 by means of rotation, pressing, sliding, or flicking. In the above-mentioned manner, relative movement can be generated between the adjusting member 201 and the mating member 104 to generate a trigger signal. Different trigger signals can adjust the dimming parameters in different ways, including but not limited to at least one of the following: adjusting the amount of dimming parameter adjustment to different degrees, adjusting the type of dimming parameter, or adjusting the method of dimming parameter adjustment (i.e., increasing or decreasing the dimming parameter), etc. Examples are given below.

[0065] In some embodiments, there are multiple mating members 104, and the adjusting member 201 can selectively engage with one of the mating members 104 to generate different trigger signals. For example, the adjusting member 201 can be selectively engaged with one of the mating members 104 by means of rotation, pressing, sliding, or flicking.

[0066] In embodiments where trigger signals are used to adjust the dimming parameters to different degrees, different mating parts 104 can correspond to different dimming parameters or different adjustment step sizes. The following description uses an example where the number of mating parts 104 equals 3. For ease of description and distinction, each mating part 104 is referred to as mating part A, mating part B, and mating part C. Optionally, the dimming parameter corresponding to mating part A is parameter 1, the dimming parameter corresponding to mating part B is parameter 2, and the dimming parameter corresponding to mating part C is parameter 3. By mating the adjusting element 201 with mating parts A, B, or C, different trigger signals can be generated to adjust the dimming parameter to parameter 1, 2, or 3. Alternatively, optionally, the adjustment step size corresponding to mating part A is 1, the adjustment step size corresponding to mating part B is 2, and the adjustment step size corresponding to mating part C is 3. By mating the adjusting element 201 with mating parts A, B, or C, different trigger signals can be generated to adjust the dimming parameter according to an adjustment amount of 1, 2, or 3 steps.

[0067] In embodiments where the trigger signal is used to adjust the type of dimming parameters, different mating parts 104 can correspond to different parameter types. Taking an example where the number of mating parts 104 is equal to 3, optionally, mating part A corresponds to parameter type 1, mating part B corresponds to parameter type 2, and mating part C corresponds to parameter type 3. By mating the adjusting element 201 with mating parts A, B, or C, different trigger signals can be generated to adjust the dimming parameters to type 1, type 2, or type 3 dimming parameters.

[0068] In an embodiment where the trigger signal is used to adjust the dimming parameter, different mating parts 104 can correspond to different adjustment methods. For example, mating part A corresponds to increasing the dimming parameter, while mating part B corresponds to decreasing the dimming parameter. By mating the adjusting part 201 with mating part A or mating part B, different trigger signals can be generated to increase or decrease the dimming parameter.

[0069] The trigger signal can also be used to achieve multiple functions simultaneously, such as adjusting the dimming parameter adjustment method and the adjustment step size of the dimming parameter at the same time. For example, the adjustment method corresponding to component A is to increase the dimming parameter by an adjustment amount of 1 step, the adjustment method corresponding to component B is to increase the dimming parameter by an adjustment amount of 2 step, and the adjustment method corresponding to component C is to decrease the dimming parameter by an adjustment amount of 1 step. By cooperating the adjustment component 201 with component A, component B, or component C, different trigger signals can be generated to adjust the dimming parameter according to the corresponding step size and adjustment method.

[0070] In some embodiments, there are multiple adjustment members 201, and one of the adjustment members 201 can be selected to cooperate with the mating member 104 to generate different trigger signals. For example, the mating member 104 can be selectively engaged with one of the adjustment members 201 by means of rotation, pressing, sliding, or flicking. Different adjustment members 201 can correspond to different dimming parameters or different adjustment step sizes. The various types of trigger signals generated in this embodiment are similar to the embodiments in which the adjustment member 201 selectively cooperates with one of the multiple mating members 104 to generate different trigger signals, and will not be described again here.

[0071] In some embodiments, the adjusting member 201 can move to different positions relative to the mating member 104 to generate different trigger signals. For example, the adjusting member 201 can be moved to different positions relative to the mating member 104 by means of rotation, pressing, sliding, or flicking. The adjusting member 201 can move to different positions relative to the mating member 104, which means that the adjusting member 201 is closer to or farther away from the mating member 104, or that the adjusting member 201 moves to different directions relative to the mating member 104, for example, the adjusting member 201 moves to the upper side, lower side, left side, or right side of the mating member 104. Different adjusting members 201 can correspond to different dimming parameters or different adjustment step sizes. The various types of trigger signals generated in this embodiment are similar to the embodiments in which the adjusting member 201 selectively mates with one of the multiple mating members 104 to generate different trigger signals, and will not be described again here.

[0072] In other embodiments, the trigger signal can be related to the amount of motion of the relative motion, with different amounts of motion generating different trigger signals. For example, the trigger signal may include an adjustment amount of the dimming parameter, which may be positively correlated with the amount of motion of the relative motion. Alternatively, the trigger signal may be related to the direction of motion of the relative motion, with different directions of motion generating different trigger signals. Alternatively, the trigger signal may be related to the number of relative motions, with different numbers of relative motions generating different trigger signals. Alternatively, the trigger signal may be related to the duration of motion of the relative motion, with different durations of relative motion generating different trigger signals. Alternatively, the trigger signal may be related to the speed of motion of the relative motion, with different speeds of relative motion generating different trigger signals. Other methods can also be used to generate different trigger signals, which will not be listed here. The types of trigger signals can be found in the foregoing embodiments and will not be repeated here.

[0073] In some embodiments, the physical control 20 can be triggered by mechanical movement. This mechanical movement includes, but is not limited to, at least one of the following: rotation, pressing, sliding, and flicking. The triggering method can be an operation on the adjusting member 201, an operation on the mating member 104, or a combination of operations on both. For example, the adjusting member 201 can be rotated, pressed, slid, or flicked; or, the adjusting member 201 can be rotated while simultaneously pressing the mating member 104; or, the adjusting member 201 and the mating member 104 can be flicked simultaneously; or, the adjusting member 201 can be slid to a specified position first, and then the mating member 104 can be pressed. Other methods can also be used to operate the adjusting member 201 and the mating member 104 to trigger the physical control 20, depending on the actual design of the physical control 20.

[0074] In some embodiments, the adjustment element 201 of the physical control 20 is configured to select and activate different mating elements 104 by rotation to be triggered. In this embodiment, the number of mating elements 104 can be greater than one. When the adjustment element 201 is rotated to different positions, different mating elements 104 can be activated, thereby triggering different trigger signals. Therefore, the user only needs to rotate the adjustment element 201 to adjust the dimming parameters of the light adjustment component 103, which is simple, convenient, and has high real-time performance.

[0075] In other embodiments, the adjustment element 201 of the physical control 20 can also be configured to select and activate different mating elements 104 by sliding or flicking. In these embodiments, the user only needs to operate the adjustment element 201 of the physical control 20 to adjust the dimming parameters of the light adjustment component 103 by simple sliding or flicking, which is simple, convenient and has high real-time performance.

[0076] The physical control 20 can be located on the light adjustment component 103 or elsewhere, such as on the housing 101. Alternatively, some components of the physical control 20 may be located on the light adjustment component 103, while others may be located on or inside the housing 101. In some embodiments, the triggering method of the physical control 20 may be related to the shape of the light adjustment component 103 and the location of the physical control 20, thereby matching the triggering method of the physical control 20 with the shape of the light adjustment component 103 and the location of the physical control 20, further improving the ease of operation of the physical control 20.

[0077] For example, if the light adjustment component 103 is circular in shape and the physical control 20 is located outside the light adjustment component 103, the triggering method of the physical control 20 can include any of the following: the adjustment element 201 of the physical control 20 is pressed, rotated, slid, or flicked to engage with the mating element 104 of the physical control 20 to generate a trigger signal. For example, the physical control 20 can be pressed, rotated, slid, or flicked to move relative to the mating element 104, thereby generating a trigger signal.

[0078] For example, if the light adjustment component 103 is circular and the physical control 20 is disposed on the light adjustment component 103, the mating part 104 can be selectively contacted and turned on by the adjustment member 201 through rotation to generate a trigger signal. Some shooting devices using circular lenses often use lens rotation to achieve functions such as focusing and aperture selection. In this embodiment, by using a circular light adjustment component 103, and disposing of the physical control 20 on the light adjustment component 103, and similarly using the rotation of the adjustment member 201 to select the mating part 104 to generate a trigger signal, the process of generating the trigger signal is similar to traditional focusing and aperture selection operations. Users do not need to spend extra time familiarizing themselves with and adapting to the new operating method, further improving the ease of operation.

[0079] For example, if the shape of the light adjustment component 103 is not circular, the triggering method of the physical control 20 may include any of the following: the adjustment element of the physical control 20 is pressed, rotated, slid or tossed to cooperate with the mating element 104 of the physical control 20 to generate a trigger signal.

[0080] In other embodiments, the triggering method of the physical control 20 may also be related to other factors, such as the size of the shooting device 10. For example, when the shooting device 10 is small, the physical control 20 may be triggered by pressing or rotating; when the shooting device 10 is large, the physical control 20 may be triggered by sliding or flicking.

[0081] In some embodiments, the mating member 104 includes a plurality of contacts, and the adjusting member 201 is sleeved around the plurality of contacts for cooperating with the plurality of contacts to perform voltage gating in order to adjust the dimming parameters of the light adjustment component 103.

[0082] Referring to Figures 3A and 3B, the contacts on the mating component 104 include multiple first contacts 1041 corresponding to multiple dimming parameters. When a target contact among the multiple first contacts 1041 is selected, the dimming parameter of the light adjustment component 103 is adjusted to the target dimming parameter corresponding to the target contact. As shown in Figure 3B, the multiple first contacts 1041 are distributed on the side of the light adjustment component 103. The adjusting component 201 is provided with a second contact 2011. The adjusting component 201 can rotate relative to the light adjustment component 103 so that the second contact 2011 contacts and selects any one of the multiple first contacts 1041. Furthermore, an anti-slip part 2012 can be provided on the outer side of the adjusting component 201 to provide an anti-slip function when the user rotates the adjusting component 201, facilitating user operation. In this embodiment, multiple mating parts 104 are arranged in a ring on the light adjustment assembly 103. The adjustment parts 201 can all be matching ring-shaped components and can be arranged on the light adjustment assembly 103. In this case, the physical control 20 adjustment parts 201 can also be called lens rings.

[0083] In some embodiments, the distance between adjacent first contact points 1041 is greater than a preset distance threshold, such that the second contact point 2011 can only select a single first contact point 1041 at a time. In this way, inaccurate adjustment caused by selecting multiple contact points at once can be avoided, thus improving the adjustment stability of the dimming parameters of the imaging device 10.

[0084] In some embodiments, the number of first contacts 1041 is greater than a preset threshold to enable near-stepless adjustment of the dimming parameters. Near-stepless adjustment refers to a near-stepless adjustment method, where adjustment can be performed without fixed levels, meaning the dimming parameters can be continuously and smoothly adjusted to the desired state or value without being limited by fixed levels. This embodiment achieves near-stepless parameter adjustment by setting the number of first contacts 1041 greater than a preset threshold. This adjustment method allows users to adjust the dimming parameters very precisely and smoothly. In other examples, the number of first contacts 1041 can be less than or equal to the preset threshold to adjust the dimming parameters to any one of a preset set of parameter levels.

[0085] In other embodiments, as shown in Figures 4A, 4B, and 4C, the adjustment member 201 can be moved to different peripheral positions of the imaging device 10. For example, the adjustment member 201 can move closer to or further away from the body 101, thereby moving to different peripheral positions of the imaging device 10. As shown in Figure 4A, when the adjustment member 201 is moved to an alignment with the peripheral position of the plurality of first contacts 1041, the second contact 2011 contacts and selects any one of the plurality of first contacts 1041. As shown in Figures 4B and 4C, when the adjustment member 201 is moved to a position not aligned with the peripheral position of the plurality of first contacts 1041, the second contact 2011 cannot contact any of the first contacts 1041. When it is necessary to adjust the dimming parameters, the adjustment member 201 can be moved to an alignment with the peripheral position of the plurality of first contacts 1041 so that the second contact 2011 contacts and selects the target contact among the plurality of first contacts 1041. When it is not necessary to adjust the dimming parameters, the adjustment component 201 can be moved to a position that is not aligned with the outer periphery of the multiple first contacts 1041, thereby preventing the user from accidentally changing the dimming parameters.

[0086] In some embodiments, the physical control 20 includes a physical button. In this embodiment, the physical button has low cost, and the user only needs to operate the physical button to adjust the dimming parameters, making the operation simple and efficient. The physical button can be a capacitive button or a mechanical button. When the physical button is a capacitive button, it may include a metal sheet, the mating part 104 includes the aforementioned metal sheet, and the adjusting part 201 includes an insulating sheet disposed above the metal sheet. The physical button 2013 is disposed on the body 101, as shown in FIG. 5, located on the top of the body 101. In other examples, the physical button may also be located at the front or side of the body 101; preferably, the physical button is located on the right side of the body 101 for easy user operation.

[0087] Optionally, there can be only one physical button. This physical button can include multiple triggering methods. These methods include, but are not limited to, multiple trigger counts, multiple trigger durations, and multiple trigger speeds. The triggering methods for increasing and decreasing dimming parameters are different. For example, a single click can be used to increase the dimming parameter, and a double click to decrease it; or a long press can be used to increase the dimming parameter, and a short press to decrease it; or a rapid click can be used to increase the dimming parameter, and a slow click to decrease it. These methods reuse the same physical button to achieve both increasing and decreasing dimming parameters, reducing the number of hardware components and lowering hardware costs.

[0088] Alternatively, the number of physical buttons can be greater than one, including buttons for increasing the dimming parameter and buttons for decreasing the dimming parameter. The button for increasing the dimming parameter is the first physical button, and the button for decreasing the dimming parameter is the second physical button. The number of both the first and second physical buttons can be greater than or equal to one. For example, if both the first and second physical buttons are one, pressing either the first or second physical button increases or decreases the dimming parameter by a fixed or varying step size. As another example, if both the first and second physical buttons are greater than one, pressing different first physical buttons increases the dimming parameter to different values ​​or increases it by different step sizes; pressing different second physical buttons decreases the dimming parameter to different values ​​or decreases it by different step sizes. This embodiment uses different physical buttons to achieve different parameter adjustment functions, reducing user errors and improving operational convenience.

[0089] In some embodiments, the physical button is also used to implement other shooting control functions besides adjusting dimming parameters (e.g., image capture or video recording), and the triggering method for adjusting dimming parameters is different from the triggering method for implementing other shooting control functions. For example, an image capture function can be implemented by clicking the physical button, and dimming parameter adjustment can be triggered by double-clicking the physical button; or, an image capture function can be implemented by long-pressing the physical button, and dimming parameter adjustment can be triggered by short-pressing the physical button; or, an image capture function can be implemented by slowly clicking the physical button, and dimming parameter adjustment can be triggered by quickly clicking the physical button.

[0090] In some embodiments, the physical control 20 includes a slider sensor. The user can perform a sliding operation on the slider sensor to adjust the dimming parameters. The slider sensor may include a control layer, the mating component 104 includes the control layer, and the adjustment component 201 includes a touch layer disposed above the control layer. The slider sensor can be a capacitive slider sensor, a resistive slider sensor, or other types of slider sensors. The slider sensor is thin, has a small thickness, and is variable in shape. Using a slider sensor allows for dimming parameter adjustment without changing the shape of the camera body 101, which is particularly suitable for situations where the camera body 101 is small and the shape of the lens 102 is not suitable for setting other types of physical controls 20 (such as physical buttons or contacts).

[0091] Users can perform sliding operations in different directions on the slider sensor. The slider sensor detects these sliding operations to increase or decrease the dimming parameters. Specifically, the dimming parameters can be increased in response to a sliding operation detected in a first sliding direction, and decreased in response to a sliding operation detected in a second sliding direction. The first and second sliding directions are opposite to each other. For example, the first sliding direction may be from left to right, and the second sliding direction from right to left. Or, the first sliding direction may be from top to bottom, and the second sliding direction from bottom to top. Or, the first sliding direction may be clockwise, and the second sliding direction may be counterclockwise.

[0092] In some embodiments, the slider sensor is disposed on the side of the light adjustment assembly 103, for example, on at least one of the upper, lower, left, or right sides of the light adjustment assembly 103. Figures 6A and 6B show a front view and a perspective view of the shooting device 10 with the slider sensor 2014 disposed on the upper side of the light adjustment assembly 103, respectively. It is understood that the figures are merely illustrative examples. In other examples, the slider sensor may be disposed at other locations on the light adjustment assembly 103, or at locations other than the light adjustment assembly 103. For example, the slider sensor may be disposed below the microphone of the shooting device, so that the user can directly slide the slider sensor left and right to adjust the dimming parameters. Furthermore, there may be multiple slider sensors. For example, different slider sensors may be used to adjust different types of dimming parameters. The specific implementation is similar to the implementation of multiple physical buttons, and will not be described in detail here.

[0093] In some embodiments, the physical control 20 may include a knob. The knob may include a retaining plate and a contact plate. The retaining plate provides support and stability to the knob, allowing it to rotate in a fixed position without moving with the knob's rotation. The contact plate is a moving part of the knob, typically moving relative to the retaining plate as the knob rotates. The contact plate is usually made of a resistive or conductive material and is used to contact the retaining plate or internal circuitry of the knob during rotation, thereby achieving changes in resistance or transmitting control signals. The mating member 104 may include the retaining plate of the knob, and the adjusting member 201 includes the contact plate of the knob.

[0094] Users can rotate the knob in different directions to increase or decrease the dimming parameters by detecting rotation in different directions. Specifically, the dimming parameters can be increased in response to the knob detecting rotation in a first direction, and decreased in response to the knob detecting rotation in a second direction. The first and second rotation directions are opposite. For example, the first rotation direction is clockwise, and the second rotation direction is counterclockwise. The knob can be located on the body 101. Figure 7 shows a schematic diagram of a knob 2015 located on the top of the body 101. It should be understood that this is only an illustrative example; in actual applications, the number and position of the knobs can be set according to actual needs.

[0095] In some embodiments, the physical control 20 includes a toggle component. The toggle component may include a guide groove and a slider. The guide groove restricts and guides the movement direction of the slider, ensuring that the slider moves along a designed trajectory during operation; the slider cooperates with the guide groove and can move along a specified path of the guide groove by manual or automatic drive. The mating component 104 may include the guide groove of the toggle component, and the adjusting component 201 may include the slider of the toggle component. As shown in FIG8, a toggle component 2016 may be provided on the top of the body 101. This toggle component 2016 includes a guide groove 2016a and a slider 2016b. The guide groove 2016a is elongated. It is understood that this is merely an illustrative example. In other examples, the position and number of toggle components, as well as the shape of the guide grooves in the toggle components, can be set according to actual needs.

[0096] Users can move the slider to different sliding positions within the guide groove to increase or decrease the dimming parameter. Specifically, the dimming parameter can be increased in response to the slider being pushed from a first sliding position to a second sliding position, and decreased in response to the slider being pushed from a second sliding position to a first sliding position. The first and second sliding positions are opposite to each other. When the guide groove is a strip-shaped guide groove, the first sliding position can be one side of the guide groove, and the second sliding position can be the other side of the guide groove. Alternatively, one of the first and second sliding positions can be the middle of the guide groove, and the other can be one of the two sides of the guide groove.

[0097] In some embodiments, as shown in FIG9, the physical control 20 is a combination control 2017, which includes a pressing part 2017a and a rotating part 2017b, with the rotating part 2017b located outside the pressing part 2017a. The pressing part 2017a and the rotating part 2017b can perform different functions. For example, the pressing part 2017a is used to select the type of dimming parameter, and the rotating part 2017b is used to adjust the size of the dimming parameter and / or switch the adjustment mode of the dimming parameter (increase or decrease). The combination control 2017 can be located on the body 101, as shown in FIG9, on the top of the body 101, or in other locations. The number of combination controls 2017 can be one or more.

[0098] In some embodiments, the physical control 20 is located at the edge of the body 101. The edge of the body 101 may include the top or side of the body 101. Referring to Figures 5, 7, and 9, the physical control 20 is located at the top of the body 101, and the physical control 20 and the light adjustment component 103 are on the same side of the body 101. This allows the user to operate the physical control 20 and the light adjustment component 103 with one hand. In other examples, the physical control 20 may also be located at other positions on the body 101, and the relative positions of the physical control 20 and the light adjustment component 103 are not limited to those described in the above embodiments.

[0099] In some embodiments, the physical control 20 is used to perform stepless or near-stepless adjustment of the dimming parameters. Stepless adjustment means that the adjustment process can achieve adjustment without any fixed levels, that is, the dimming parameters can be continuously and smoothly adjusted to the desired state or value without being limited by fixed levels. Near-stepless adjustment refers to a method that is close to stepless adjustment. Through stepless or near-stepless adjustment, users can adjust the dimming parameters very finely and smoothly. In other embodiments, the physical control 20 is used to adjust the dimming parameters to any one of a plurality of preset parameter levels. For example, 3 to 5 parameter levels can be set, each parameter level corresponding to a parameter value of the dimming parameter. The level adjustment has a clear fixed position or an optional preset value, and the user can easily select one of the parameter levels without special skills or fine operation, thus having low complexity.

[0100] In some embodiments, the electrical control parameters are related to the dimming parameters, and the dimming parameters can be adjusted by adjusting the electrical control parameters of the light adjustment component 103. These electrical control parameters include, but are not limited to, at least one of the following: voltage, current, and magnetic field.

[0101] In some embodiments, the capturing device 10 further includes an image processing unit for performing image processing on images captured by the capturing device 10 based on adjusted dimming parameters and / or adjusted electrical control parameters. Image processing includes, but is not limited to, at least one of the following: color correction processing, brightness processing, sharpening processing, contrast adjustment, and noise reduction processing. For example, when the light adjustment component 103 is a neutral density filter, the dimming parameter can correspondingly be a light reduction value. Different light reduction values ​​affect the intensity of the light signal entering the lens 102. When the light reduction value is large, the intensity of the light signal entering the lens 102 is low, typically requiring a slower shutter speed or a larger aperture to compensate during shooting. A longer exposure time may be needed to achieve proper exposure. Due to the longer exposure time, the image may capture more light information, but there is also a risk of overexposure. When processing these images, it may be necessary to balance the overall exposure by reducing the brightness of highlight areas or enhancing shadow details. Additionally, long exposures typically introduce more noise, thus requiring more noise reduction processing to maintain image sharpness and detail. In this embodiment, image processing is performed based on the adjusted dimming parameters and / or the adjusted electrical control parameters, which makes the image processing method more compatible with the actual application scenario, thereby improving image quality.

[0102] In some embodiments, referring to Figures 10A and 10B, the imaging device 10 further includes a power management chip 108 for adjusting electrical control parameters in response to a trigger signal input via the physical control 20. The trigger signal may include the type, adjustment method (increase or decrease), and adjustment amount of the electrical control parameters. The power management chip 108 can adjust the corresponding type of electrical control parameter according to the indication of the trigger signal, using the appropriate adjustment method and adjustment amount, thereby achieving adjustment of the dimming parameters.

[0103] In some embodiments, referring to Figures 10A and 10B, the imaging device 10 further includes a SOC chip 107, used to send the adjusted dimming parameters and / or adjusted electrical control parameters to the display unit (e.g., screen) 50 of the imaging device 10, and / or to the image processing unit 106 of the imaging device 10. By sending the adjusted dimming parameters and / or adjusted electrical control parameters to the display unit 105, the display unit 105 can display the adjusted dimming parameters and / or adjusted electrical control parameters, allowing the user to intuitively observe the adjusted dimming parameters and / or adjusted electrical control parameters on the display unit 105. In this way, the user only needs to monitor the screen when adjusting the dimming parameters, avoiding blind adjustment of the dimming parameters. By sending the adjusted dimming parameters to the image processing unit 106, the image processing unit 106 can perform image processing based on the adjusted dimming parameters, thereby improving image quality.

[0104] As shown in Figure 10A, the SOC chip 107 can be electrically connected between the physical control 20 and the power management chip 108. That is, the structure switching method is designed to be connected to the SOC via hardware. After receiving the signal, the SOC outputs a power control signal to the power management chip to output voltage, thereby controlling the electronic filter to adjust dimming parameters, such as transmittance. Alternatively, as shown in Figure 10B, the structure switching method is designed as a hardware circuit scheme, where the SOC chip 107 can be electrically connected to the physical control 20 via the power management chip 108. In this embodiment, using the physical control 20 to directly connect to the power management chip 108 or directly to the SOC avoids the inconvenience to user operation caused by software triggering.

[0105] In some embodiments, the light adjustment component 103 includes at least one dimming mode. The at least one dimming mode may include a first dimming mode for adjusting dimming parameters independent of the wavelength of light. The first dimming mode includes a light reduction adjustment mode or a soft light adjustment mode. In this embodiment, since the wavelength of light is not changed, all types of light can be collected into the imaging device. The at least one dimming mode may also include a second dimming mode for adjusting wavelength-related dimming parameters of light. The second dimming mode includes at least one of the following: a UV value adjustment mode, a gradient color adjustment mode, and a color filter adjustment mode. In this embodiment, wavelengths of light that are not desired can be filtered out, improving the user experience.

[0106] When the light adjustment component 103 includes multiple dimming modes, physical controls can also be used to adjust the dimming modes of the light adjustment component 103. This embodiment achieves multiple dimming modes with a single light adjustment component 103, which can effectively reduce the number of light adjustment components 103, thereby reducing hardware costs.

[0107] For example, the physical control 20 may include multiple triggering methods, each used to trigger multiple dimming modes. When the physical control 20 is a physical button, the multiple triggering methods include, but are not limited to, long press, short press, single click, double click, triple click, etc., of the physical button. As one implementation, the light adjustment component 103 can be set to a light reduction mode, UV value adjustment mode, soft light adjustment mode, or gradient color adjustment mode by long press, single short press, double short press, and triple short press of the physical button, respectively. When the mating part 104 of the physical control 20 includes multiple first contacts, and the adjustment part 201 of the physical control 20 includes second contacts, different first contacts can correspond to different dimming modes. Different first contacts can be selected by the second contacts, thereby setting the light adjustment component 103 to different dimming modes. When the physical control 20 is a slider sensor, the light adjustment component 103 can be set to different dimming modes when the slider sensor detects sliding operations in different sliding directions. When the physical control 20 is a knob, the light adjustment component 103 can be set to different dimming modes when the knob detects rotation in different directions. When the physical control 20 is a toggle component, the light adjustment component 103 can be set to different dimming modes when the slider of the toggle component moves to different sliding positions of the guide groove of the toggle component. The above embodiments use different triggering methods to set the light adjustment component 103 to different dimming modes, which can realize the setting and switching of multiple dimming modes through a single physical control 20, thereby reducing the number of physical controls 20 and reducing hardware costs.

[0108] In some embodiments, the number of physical controls 20 may be greater than one. Multiple physical controls 20 are used to trigger multiple dimming modes. In this embodiment, the number of physical controls 20 can be matched with the number of dimming modes, so that different dimming modes can be set through different physical controls 20, reducing operational complexity.

[0109] The physical control 20 used to adjust dimming parameters and the physical control 20 used to adjust dimming modes can be the same physical control 20 or different physical controls 20. When the physical control 20 used to adjust dimming parameters and the physical control 20 used to adjust dimming modes are the same physical control 20, the function of the physical control 20 can switch between adjusting dimming parameters and adjusting dimming modes.

[0110] For example, the shooting device 10 may include a switching control for switching the function of the physical control 20 to adjust dimming parameters or adjust dimming mode. Optionally, the switching control can be an existing control on the shooting device 10, that is, adding the function of switching dimming parameters and adjusting dimming mode to an existing control, thereby achieving reuse of the same control and reducing the number of hardware components and costs. Different triggering methods can be used on existing controls to achieve the original function or the switching function of dimming parameters and adjusting dimming mode. Alternatively, a new switching control can be added to the shooting device 10 to achieve the function of switching dimming parameters and adjusting dimming mode.

[0111] For example, different triggering methods can be used for the physical control 20, allowing its function to switch between adjusting dimming parameters and adjusting dimming modes. For instance, a long press on the physical control 20 switches to the function of adjusting dimming parameters, while a short press switches to the function of adjusting dimming modes.

[0112] In other embodiments, the function of the physical control 20 can be switched to adjust dimming parameters or adjust dimming mode by voice input or gesture operation, or other methods can be used to switch between adjusting dimming parameters and adjusting dimming mode, which will not be listed here.

[0113] In some embodiments, multiple dimming modes correspond to multiple parameter types. For example, the parameter type corresponding to the light reduction mode is light reduction, the parameter type corresponding to the UV value adjustment mode is UV value, the parameter type corresponding to the soft light adjustment mode is soft light parameter, the parameter type corresponding to the gradient color adjustment mode is gradient color parameter, and the parameter type corresponding to the color filter adjustment mode is color filter parameter.

[0114] After the dimming mode of the light adjustment component 103 is adjusted to the target dimming mode among multiple dimming modes, the parameter type of the dimming parameters of the light adjustment component 103 can be adjusted to the target parameter type corresponding to the target dimming mode. For example, after the dimming mode of the light adjustment component 103 is adjusted to the light reduction mode, the parameter type of the dimming parameters of the light adjustment component 103 is adjusted to the light reduction value; after the dimming mode of the light adjustment component 103 is adjusted to the UV value adjustment mode, the parameter type of the dimming parameters of the light adjustment component 103 is adjusted to the UV value. This embodiment can adjust different dimming parameters by setting different dimming modes, thereby obtaining different shooting effects.

[0115] In some embodiments, the dimming parameters include a plurality of preset parameter levels. A preset triggering method can be used to trigger the physical control 20, causing the dimming parameters to be adjusted from a first parameter level to a second parameter level. Optionally, at least one parameter level may be included between the first and second parameter levels. For example, suppose the plurality of parameter levels include level 1, level 2, level 3, level 4, and level 5, wherein the dimming parameters corresponding to level 1, level 2, level 3, level 4, and level 5 increase sequentially; that is, level 2 is the next level after level 1, level 3 is the next level after level 2, and so on. In the above embodiments, in response to triggering the physical control 20 using a preset triggering method, the dimming parameters can be adjusted from the dimming parameters corresponding to level 1 to the dimming parameters corresponding to level 3, level 4, or level 5. Alternatively, in response to triggering the physical control 20 using a preset trigger method, the dimming parameter can be adjusted from the dimming parameter corresponding to level 4 to the dimming parameter corresponding to level 2 or level 1. This adjustment method is called the skip-level adjustment method. In some cases, there may be a large number of possible dimming parameter levels. If the dimming parameter is adjusted sequentially between multiple levels, the time spent is considerable. By using the skip-level adjustment method, the time spent in adjusting the dimming parameter can be effectively reduced, improving the efficiency of parameter adjustment.

[0116] It is understood that the above-described method of adjusting the dimming level is merely illustrative. In other examples, other methods can also be used to adjust the dimming parameters. For instance, when triggering the physical control 20 using a preset trigger method, the dimming parameter can be adjusted from the first parameter level to the third parameter level, where the first and third parameter levels are adjacent. For example, when the first parameter level is level 2, the second parameter level can be level 1 or level 3. Alternatively, when triggering the physical control 20 using a preset trigger method, the dimming parameter can first be adjusted from the first parameter level to the third parameter level, and then the third parameter level can be adjusted to the fourth parameter level, where the first and third parameter levels are adjacent, and at least one parameter level can be included between the third and fourth parameter levels. For example, the first parameter level is level 2, the second parameter level is level 3, and the third parameter level is level 5.

[0117] In some embodiments, the light adjustment component 103 is located on the outermost side of the lens 102. The light adjustment component 103 may include a protective lens for protecting the lens 102. This protective lens may be, for example, a lens from an electronic filter; that is, a lens from an electronic filter is reused as a protective lens. In related technologies, a protective cover is required at the front end of the lens 102. This protective cover is typically made of ordinary glass and only serves to protect the optical lens, without regulating the light signal. In this embodiment, the light adjustment component 103 can be used to both protect the lens 102 and regulate the light signal, achieving reuse of the light adjustment component 103. This eliminates the need for an additional lens protective cover to protect the lens 102, reducing the number and size of hardware components and lowering hardware costs.

[0118] One or more of the solutions in this disclosure have at least the following advantages:

[0119] (1) Replace the protective glass of the lens cap of the action camera in the relevant scheme with a light adjustment component (such as an electronic filter, or better yet, an electronic ND filter), which can protect the optical lens while also functioning as an electronic filter, and can achieve new functions without adding structural components.

[0120] (2) Adding a circular adjustment component to the outside of the circular light adjustment component allows for the selection of different contact points by rotation, thereby enabling the selection of different electrical control parameters (such as voltage) and thus adjusting the dimming parameters. For non-circular light adjustment components (e.g., rectangular or square light adjustment components), other physical controls (such as physical buttons) can be added to switch the dimming mode or the magnitude of electrical control parameters (such as voltage). Alternatively, different voltages can be selected to adjust the dimming parameters by reusing the same physical control (such as the number of times a physical button is pressed / the duration of the button press). This method is suitable for adjusting the dimming parameters of light adjustment components of various shapes.

[0121] (3) A slider sensor can be used to add a slider sensor to the lens frame or body. Sliding it in different directions can determine the increase or decrease of the signal, so as to achieve stepless adjustment and adjust the dimming parameters without changing the shape of the body.

[0122] (4) The above structure can not only adjust the light reduction filter effect through voltage control, but also select the dimming mode through different triggering methods to achieve filter effects such as UV filter, gradient filter, soft light filter and color filter.

[0123] (5) The mode or voltage value switched by the above mode can be sent to the screen for display in real time, and the user can obtain the parameter information in real time when adjusting the dimming parameters.

[0124] (6) The mode or voltage level switched by the above mode can be sent to the SOC chip in real time as input parameters for the image processing algorithm of the shooting device. The light adjustment component provides parameters for real-time adaptive adjustment, avoiding hardware triggering of dimming parameter adjustment. If the image processing module does not detect the change in dimming parameter, the image processing algorithm will not make adaptive adjustment, which will affect the user experience.

[0125] (7) Using physical controls such as buttons or contact-based adjustment components (e.g., contact-based lens rings) or slider sensors allows users to operate the light adjustment components mechanically, increasing ease of use and improving user experience.

[0126] (8) The solution disclosed herein can be used in products such as action cameras. Since action camera screens are usually small, it is not suitable to adjust the light dimming parameters by operating the screen. The method of the embodiments disclosed herein can adjust the dimming method based on physical controls. The adjustment method is convenient and efficient, and is more friendly to shooting devices with small screen sizes.

[0127] (9) In this embodiment, a traditional filter is replaced with an electronic filter, and the electronic filter replaces the protective glass on the original lens cap. Contacts are provided within the lens ring, and the lens cap supports rotation (hardware-controlled adjustment of dimming parameters, such as transmittance selection) to select the contacts. Contact selection changes the voltage of the electronic filter, achieving functional adjustment. This allows the lens and light adjustment assembly to be completely sealed, eliminating the need for manual removal and replacement of the light adjustment assembly.

[0142] The electro-optical adjustment component 403 of this embodiment can both adjust the light signal and protect the lens 402, achieving multiple functions with a single component. This eliminates the need for an additional lens cover, reducing hardware costs. Furthermore, since the dimming parameters of the electro-optical adjustment component 403 are adjustable, a single component can be used to obtain various dimming parameters without requiring different adjustment components. This avoids the problem of the lens 402 being unprotected when replacing adjustment components.

[0143] In this embodiment, the body 401, lens 402, and electronic light adjustment component 403 correspond to the body 101, lens 102, and light adjustment component 103 in the foregoing embodiments, respectively.

[0150] The electro-optical light adjustment component 503 of this embodiment can simultaneously perform two functions: adjusting the light signal and protecting the lens 502. This achieves multiple functions using a single component, eliminating the need for an additional lens cover and reducing hardware costs. Furthermore, by using a physical control 504 to adjust the dimming parameters of the electro-optical light adjustment component 503, the dimming parameters can be adjusted conveniently and quickly without needing to replace the component with one of different specifications or parameters.

[0151] In this embodiment, the body 501, lens 502, electronic light adjustment component 503, and physical control 504 correspond to the body 101, lens 102, light adjustment component 103, and physical control 20 in the aforementioned embodiments, respectively.
