However, the mainstream mobile phone camera and mobile phone flash light control scheme at present is single, and the main form is as follows: the mobile phone camera lens and the flash lamp secrecy sticker are registered before a user enters a specific area, the secrecy sticker is pasted on equipment, when the user leaves the specific area, the integrity of the secrecy sticker is checked, the scheme is complicated in flow and operation, specific manpower input is needed, the mobile phone camera lens and the flash lamp are stained due to the fact that glue is pasted, the secrecy sticker can be torn midway by the user, and the mobile phone camera and the flash lamp cannot be completely eradicated, and the user can take pictures maliciously and randomly by using the mobile phone camera and the mobile phone flash lamp.

Therefore, in order to overcome the above-mentioned drawbacks, embodiments of the present application provide an electrochromic controller, method, apparatus, and electronic device. The electrochromic controller and the method are applied to electronic equipment which can be the intelligent terminal, and particularly, the electrochromic controller can replace the materials of a camera lens glass cover plate and a flash lamp module cover plate in the intelligent terminal with electrochromic glass materials, so that the electrochromic controller can control the colors of the camera lens glass cover plate and the flash lamp module cover plate to be darkened through electric signals, and normal use of a camera and a flash lamp is influenced.

Referring to fig. 1, fig. 1 shows an electronic device provided in an embodiment of the present application, which includes a camera module including a camera lens 20 and an image sensor (not shown), and a flash module including a flash 30.

The camera lens 20 is composed of a plurality of optical lenses for forming an object image, and may be a single focus lens or a zoom lens. The camera lens 20 is movable in the optical axis direction under the control of a lens driver, which controls the focal position of the camera lens 20 based on a control signal from a lens driving control circuit, and in the case of a zoom lens, the focal distance may be controlled.

An image sensor located under the camera lens 20 collects an original image signal through the camera lens 20, and specifically, the image sensor collects a current environment image through the camera lens 20, and sends the collected current environment image to an image processing unit, and the image processing unit obtains the brightness of the current environment light according to the brightness of the current environment image. The image sensor may be a CMOS (Complementary Metal Oxide Semiconductor) sensor, a CCD (Charge-coupled Device) sensor, or the like.

Wherein, the flash light provides certain exposure compensation when being used for gathering the image for the camera module, for example, improves ambient brightness, also can provide the illumination in some application scenes simultaneously.

As an embodiment, the electronic device further includes an electrochromic controller 10. Specifically, the electrochromic controller 10 includes a first electrochromic cover 110, a second electrochromic cover 120, and a signal generator 130.

The first electrochromic cover 110 covers the camera lens 20, that is, when the camera module shoots a target object, light reflected or emitted by the target object needs to be transmitted through the first electrochromic cover 110, and then is collected to an image plane, that is, a photosensitive plane of the image sensor, through the camera lens 20, so as to form an image. In addition, the first electrochromic cover 110 may also function to protect the camera lens 20.

In some embodiments, the first electrochromic cover 110 covers the camera lens cover, and the camera lens cover covers the camera lens 20, that is, the first electrochromic cover 110 covers the camera lens cover of the electronic device. That is, the first electrochromic cover 110 indirectly covers the camera lens 20. In other embodiments, the first electrochromic cover 110 replaces the above-mentioned camera lens glass cover, i.e., the camera lens 20 is directly covered by the first electrochromic cover 110.

Specifically, the first electrochromic cover 110 is made of an electrochromic material, wherein the electrochromic material refers to a phenomenon that optical properties (reflectivity, transmittance, absorptivity, and the like) of the material undergo a stable and reversible color change under the action of an applied electric field, and the material is visually represented as a reversible change in color and transparency. Materials with electrochromic properties are referred to as electrochromic materials. The electrochromic material has bistable performance, and the electrochromic display made of the electrochromic material does not need a backlight lamp, and does not consume power as long as the display content is not changed after a static image is displayed, so that the aim of saving energy is fulfilled. Compared with other displays, the electrochromic display has the advantages of no visual blind angle, high contrast and the like. The automatic anti-dazzling rearview mirror prepared from the electrochromic material can adjust the intensity of reflected light according to the intensity of external light through an electronic induction system, so that the anti-dazzling effect is achieved, and driving is safer.

As an embodiment, the first electrochromic cover 110 may be an electrochromic glass having a light absorption transmission adjustability under an electric field, and selectively absorbing or reflecting external heat radiation and internal heat diffusion, thereby reducing a large amount of energy that must be consumed in office buildings and residential houses to keep cool in summer and warm in winter. Meanwhile, the purposes of improving the natural illumination degree and preventing peeping are achieved.

The electrochromic glass may include: glass or transparent substrate material, transparent conductive layer, electrochromic layer, electrolyte layer, ion storage layer, transparent conductive layer, glass or transparent substrate material. A certain voltage is applied between the two transparent conductive layers, the electrochromic layer material generates oxidation reduction reaction under the action of the voltage, the color is changed, and the electrolyte layer is made of special conductive materials. For example, a solution or a solid electrolyte material containing lithium perchlorate, sodium perchlorate, or the like. The ion storage layer can store corresponding counter ions when the electrochromic material undergoes an oxidation-reduction reaction, and the charge balance of the whole system is kept. For example, if the electrochromic layer material is an anodic oxidation color-changing material, the ion storage layer may be a cathodic reduction color-changing material.

Therefore, the transmittance of the first electrochromic cover 110 is related to its color depth, i.e., the deeper the color, the lower the transmittance, and the lighter the color, the higher the transmittance.

The second electrochromic cover 120 covers the flash 30, and specifically, the second electrochromic cover 120 covers a light exit surface or a light exit port of the flash 30, that is, light emitted by the flash 30 needs to be transmitted through the second electrochromic cover 120 and then emitted. The second electrochromic cover 120 may also be made of an electrochromic material, and specifically, refer to the foregoing embodiment of the first electrochromic cover 110.

Similarly, in some embodiments, the second electrochromic cover 120 covers the flash module cover, and the flash module cover covers the flash 30, that is, the second electrochromic cover 120 covers the flash module cover of the electronic device. I.e., the second electrochromic cover 120 indirectly covers the flash 30. In other embodiments, the second electrochromic cover 120 replaces the above-mentioned cover of the flash module, that is, the second electrochromic cover 120 directly covers the flash 30.

In the embodiment of the present application, the first electrochromic cover 110 may completely cover the camera lens 20, that is, when the first electrochromic cover 110 covers the camera lens 20, a first surface of the first electrochromic cover 110 is opposite to a second surface of the camera lens 20, and a surface area of the first surface is greater than or equal to a surface area of the second surface, where the second surface is a surface closest to the object side among optical elements of the camera lens 20. Similarly, the second electrochromic cover 120 may also completely cover the flash 30.

The signal generator 130 is electrically connected to the first electrochromic cover 110 and the second electrochromic cover 120, respectively, and as an embodiment, the signal generator 130 is electrically connected to the conductive layer of the first electrochromic cover 110 and the conductive layer of the second electrochromic cover 120 through a wire.

As an embodiment, the signal generator 130 may be electrically connected to the first electrochromic cover 110 and the second electrochromic cover 120 through a conductive frame. Specifically, referring to fig. 2 and 3, the electrochromic controller 10 further includes: a first conductive frame body 111 and a second conductive frame body 121.

The first electrochromic cover 110 covers the camera lens 20 through the first conductive frame 111. Specifically, the first conductive frame 111 serves as a mounting frame for the first electrochromic cover 110, for mounting the first electrochromic cover 110 on the camera lens 20. In one embodiment, the first conductive frame 111 may be a frame that matches the contour of the second surface of the camera lens 20, for example, if the second surface of the camera lens 20 is a circular surface, the contour of the second surface is a circle, and the first conductive frame 111 may be a circular ring frame.

As an embodiment, the contour of the first surface of the first electrochromic cover 110 may also match the contour of the first conductive frame 111, for example, the contour of the first surface of the first electrochromic cover 110 may also be circular. In addition, the size of the contour of the first surface of the first electrochromic cover 110, the contour of the first conductive frame 111, and the contour of the second surface of the camera lens 20 may be matched, i.e., the size of the contour of the first surface of the first electrochromic cover 110, the contour of the first conductive frame 111, and the contour of the second surface of the camera lens 20 may be the same.

The first conductive frame 111 is electrically connected to the signal generator 130, and the first conductive frame 111 is used for transmitting the electrical signal to the first electrochromic cover 110. In some embodiments, the first conductive frame 111 is connected to the signal generator 130 through a signal line, specifically, one end of the signal line is connected to an output end of the signal generator 130, the other end of the signal line is welded to the first conductive frame 111, and the first conductive frame 111 is in contact with the first electrochromic cover 110 and can transmit an electrical signal to the first electrochromic cover 110. In one embodiment, the first conductive frame 111 is in contact with the conductive layer of the first electrochromic cover 110, so that the signal generator 130 is electrically connected to the first electrochromic cover 110 through the first conductive frame 111.

The second electrochromic cover 120 covers the flash 30 through the second conductive frame 121, and the second conductive frame 121 is electrically connected to the signal generator 130, and is configured to transmit the electrical signal to the second electrochromic cover 120. Similar to the first conductive frame 111, the outline of the second conductive frame 121 is the same as the outline of the light-emitting surface of the flash lamp 30, for example, if the light-emitting surface of the flash lamp 30 is circular, the outline of the second conductive frame 121 is also circular, and the size of the outline of the surface of the second electrochromic cover 120, the outline of the second conductive frame 121 and the outline of the light-emitting surface of the flash lamp 30 can be matched.

The signal generator 130 is configured to receive an electrochromic control signal, and input an electrical signal to a target electrochromic cover plate according to the electrochromic control signal, where the electrical signal is used to control the color of the target electrochromic cover plate to deepen, and the target electrochromic cover plate is at least one of the first electrochromic cover plate and the second electrochromic cover plate.

As an implementation manner, the specific implementation manner that the signal generator controls the color deepening of the target electrochromic cover plate according to the electrochromic control signal may refer to the subsequent method embodiments.

Referring to fig. 4, fig. 4 shows an electrochromic control method provided in an embodiment of the present application, where the method is applied to the electrochromic controller, and an execution subject of the method may be the signal generator, and specifically, the method may include: s401 to S402.

S401: an electrochromic control signal is received.

The electrochromic control signal is used as a starting instruction for starting an electrochromic function, and the electrochromic function can be an operation of controlling at least one of the first electrochromic cover plate and the second electrochromic cover plate to change color through electrochromic change, and specifically, the color can be deepened.

As an embodiment, the electronic color-changing control signal may be a clock signal, a parameter, a message, or the like. In some embodiments, the electrochromic control signal may be input by a user operating the electronic device, the user inputting the electrochromic control signal through an input device of the electronic device. In other embodiments, the electronic device or signal generator may obtain electrochromic control signals transmitted by other terminals received within the current area. In still other embodiments, it may also be determined that an electrochromic control signal is received when the electronic device enters a certain area or scene. For example, the electronic device detects whether the currently located area is a designated area, and if so, determines that the electrochromic control signal is received, wherein the designated area may be an area in which at least one of the camera and the flash needs to be disabled.

As one embodiment, the electronic device comprises a processor, and the signal generator receives an electrochromic control signal sent by the processor. Specifically, the signal generator is connected to the processor and configured to receive the electrochromic control signal sent by the processor. For example, an electrochromic request input by a user through the electronic device is collected by the processor, and an electrochromic control signal is generated according to the electrochromic request. For another example, the processor may receive an electrochromic request sent by another terminal, and generate an electrochromic control signal according to the electrochromic request.

S402: and inputting an electric signal to the target electrochromic cover plate according to the electrochromic control signal.

The electric signal is used for controlling the color deepening of the target electrochromic cover plate so as to reduce the light transmittance of the target electrochromic cover plate, wherein the target electrochromic cover plate is at least one of a first electrochromic cover plate and a second electrochromic cover plate.

As an embodiment, an electrical parameter for generating an electrical signal is preset, where the electrical parameter may include parameters such as amplitude, duty ratio, frequency, or phase, and the electrochromic control signal may serve as a trigger request, that is, when the signal generator detects that the electrochromic control signal is obtained, the signal generator generates an electrical signal according to the preset electrical parameter, and inputs the electrical signal to the target electrochromic cover. The electric signal can control the color change of the target electrochromic cover plate, namely, the light transmittance of the target electrochromic cover plate can be reduced. Specifically, the color of the first electrochromic cover plate is deepened, for example, the first electrochromic cover plate is changed into a dark black color, so that the light of the external light entering the camera lens through the first electrochromic cover plate is very little, the camera cannot smoothly collect the image of the external object, and the collected image is the image of the first electrochromic cover plate with the deepened color. In a similar way, the color of the second electrochromic cover plate is deepened, and light rays emitted by the flash lamp cannot penetrate through the second electrochromic cover plate, so that the user cannot normally use the flash lamp. For specific principles, reference may be made to the above description, which is not repeated herein.

As an embodiment, the electrochromic control signal not only acts as a trigger request, but can also instruct the signal generator to generate an electrical signal with specified parameters for characterizing the length and depth of the desired color deepening, as will be described in the examples that follow.

As an embodiment, the electrical signal may be a current signal or a voltage signal.

The target electrochromic cover plate is at least one of the first electrochromic cover plate and the second electrochromic cover plate, namely, the device which needs to be forbidden at this time in the camera and the flash lamp is used as a device to be forbidden, and the electrochromic cover plate corresponding to the forbidden device is used as the target electrochromic cover plate.

For example, if the device to be disabled is a camera, the target electrochromic cover is a first electrochromic cover, if the device to be disabled is a flash, the target electrochromic cover is a second electrochromic cover, and if the device to be disabled is a camera and a flash, the target electrochromic cover is a first electrochromic cover and a second electrochromic cover.

As an embodiment, the device to be disabled may be determined by a user through an input of the electronic device, for example, a selection interface may be displayed on a screen of the electronic device, at which at least one of the disabled camera and the flash is selected, so that the electronic device determines the target electrochromic cover according to the device to be disabled input by the user based on the interface.

As another implementation, the device to be disabled may be determined by a current scene where the electronic device is located, so as to be able to determine the target electrochromic cover, specifically, please refer to the following examples.

Referring to fig. 5, fig. 5 illustrates an electrochromic control method provided in an embodiment of the present application, where the method is applied to the electrochromic controller, and an execution subject of the method may be the signal generator, and specifically, the method may include: s501 to S504.

S501: an electrochromic control signal is received.

In this embodiment, the signal generator is connected to the processor and configured to receive the electrochromic control signal sent by the processor, and the signal generator includes a voltage output device and a signal processing device. Specifically, as shown in fig. 6, the signal generator includes: the processor is connected with the input end of the signal processing device 132, the output end of the signal processing device 132 is connected with the input end of the voltage output device 131, and the output end of the voltage output device 131 is electrically connected with at least one of the first electrochromic cover plate 110 and the second electrochromic cover plate 120.

As an embodiment, the output terminal of the voltage output device 131 may include two, namely a first output terminal and a second output terminal, the first output terminal is connected to the first electrochromic cover 110, and the second output terminal is connected to the second electrochromic cover 120. The voltage output device 131 is capable of outputting an electrical signal independently of at least one of the first output terminal and the second output terminal.

In another embodiment, one output terminal of the voltage output device 131 is electrically connected to at least one of the first electrochromic cover 110 and the second electrochromic cover 120 through a switch module. Specifically, the switch module at least includes four connection ends, the four connection ends include a first connection end, a second connection end, a third connection end and a fourth connection end, the output end of the voltage output device 131 is connected with the first connection end, the second connection end is electrically connected with the first electrochromic cover plate 110, the third connection end is electrically connected with the second electrochromic cover plate 120, the fourth connection end is simultaneously electrically connected with the first electrochromic cover plate 110 and the second electrochromic cover plate 120, and the switch module can control the first connection end to be respectively connected with or disconnected from the second connection end, the third connection end and the fourth connection end according to a control signal.

The signal processing device 131 is configured to receive the electrochromic control signal sent by the processor, generate an electrochromic logic signal according to the electrochromic control signal, and transmit the electrochromic logic signal to the voltage output device. The voltage output device 132 is configured to output a voltage signal corresponding to the electrochromic logic signal according to the electrochromic logic signal, where the electrochromic logic signal includes a voltage parameter corresponding to a voltage signal to be generated.

The electrochromic logic signal may be a clock signal, and the signal processing device may be a clock generating device, for example, a clock generator, which is capable of generating a clock signal with a certain logic level variation. For example, the signal processing device may be a clock chip, for example, a DS1302 chip, and the processor is connected to an I/O port of the clock chip, and the SCLK of the clock chip is used as an output terminal of the signal processing device for outputting the electrochromic logic signal.

As an embodiment, the electrochromic control signal includes a duration parameter for determining a duration of the electrical signal and a depth parameter for determining a magnitude of the electrical signal, wherein the duration of the electrical signal corresponds to a duration length of the electrochromic process and the magnitude of the electrical signal corresponds to a color depth value of the electrochromic process.

As an embodiment, the time length parameter and the depth parameter may also be set by a user on a specified interface of the electronic device, for example, the specified interface may be the above-mentioned selection interface. As shown in fig. 7, the selection interface includes a first control button corresponding to the camera and a second control button corresponding to the flash, the first control button can be operated to set the target electrochromic cover to include a first electrochromic cover, i.e., disable the camera, and the second control button can be operated to set the target electrochromic cover to include a second electrochromic cover, i.e., disable the flash.

When at least one of the first electrochromic cover plate and the second electrochromic cover plate is selected, the displayed duration setting component and the depth setting component become operable states, and then a user can input a duration parameter through the duration setting component and input a depth parameter through the depth setting component. As an embodiment, in order to avoid that the user of the electronic device re-enables the camera or flash that has been disabled through the selection interface, i.e. by operating the first control button and/or the second control button, cancels the process of darkening the color of the first electrochromic cover and/or the second electrochromic cover, an administrator key may be set, i.e. only entering the correct administrator key can enter the selection interface, and the administrator key has time-validity, i.e. valid within a specified time period and invalid outside the specified time period, and in case the administrator key is invalid, the user may enter the selection interface without entering the administrator key and operate the selection interface. The end time of the specified time period may be an end corresponding to the set duration, that is, the administrator key may be automatically invalidated after the current disabling of the camera and/or the flash is cancelled.

The voltage output device can output a voltage signal corresponding to the electrochromic logic signal according to the electrochromic logic signal.

S502: and determining the duration of the electric signal according to the duration parameter.

In the embodiment of the present application, the electrical signal output by the voltage output device for controlling the target electrochromic cover plate is a voltage signal.

As an implementation manner, the electrochromic control signal includes a duration parameter and a depth parameter, and the signal processing device receives the electrochromic control signal, obtains the duration parameter and the depth parameter, and generates the electrochromic logic signal according to the duration parameter and the depth parameter, so that the electrochromic logic signal can include a voltage parameter corresponding to the voltage signal to be generated, and then the voltage parameter can include a duration and an amplitude.

Specifically, the signal processing device determines the duration of the working level in the electrochromic logic signal to be generated according to the duration parameter in the electrochromic control signal and the working level of the voltage output device.

The voltage output device can output an electrical signal or stop outputting the electrical signal according to a change in logic level of the electrochromic logic signal, and the working level is a level for controlling the voltage output device to output the electrical signal. For example, the active level of the enable terminal is high level, that is, when the electrochromic logic signal is high level, the voltage output device outputs the electrical signal, and when the electrochromic logic signal is low level, the voltage output device does not output the electrical signal. Therefore, the duty ratio is used to measure the duration of the active level in the electrochromic logic signal, and the duration of the active level is consistent with the duration parameter, for example, the duration parameter is 30 minutes, which means that the voltage output device outputs the voltage signal for 30 minutes. Then the duration of the active level in the electrochromic logic signal is also 30 minutes, as an embodiment. Thus, the voltage output device continues to output an electrical signal triggered by an active level that lasts for 30 minutes.

Thus, the duration of the generated electrical signal is the same as the duration of the desired electrochromic operation (e.g., x hours), and the voltage (amplitude, e.g., y volts) of the generated electrical signal produces a depth of latitude greater than the depth of the desired darkened color, thereby enabling the timed coloring and fading effects.

As an embodiment, the electrochromic controller further comprises a signal receiving device for receiving an electric wave signal and sending the electric wave signal to the processor, and instructing the processor to generate the electrochromic control signal.

The signal processing means is adapted to receive an electrochromic control signal (e.g., short-time coloring, long-time coloring, light coloring, deep coloring, etc.) generated by the processor based on the electrical wave signal. Meanwhile, the signals are converted into electrochromic logic control signals according to different scenes, and are converted into x time and +/-y voltage control information through signal analysis processing.

Referring to fig. 10, fig. 10 shows an electrochromic control method provided in an embodiment of the present application, where the method is applied to the electrochromic controller, and an execution subject of the method may be the signal generator, and specifically, the method may include: s1001 to S1004.

S1001: an electrochromic control signal is received.

S1002: and determining scene information of the scene where the electronic equipment is located currently.

The scene information may be a scene type of a scene in which the scene is currently located, for example, the scene type may include an exhibition hall type, a conference type, and the like.

As an embodiment, the scene information determination may be location information, current time, and event information collected by the electronic device, where the event information includes subject content, start time, participation place, and the like of a user planning to participate in an event, and a scene type corresponding to the event can be obtained by analyzing the event information, for example, a topic of "third group meeting" may determine that the scene type corresponding to the event is a meeting. The event information may be a received notification message or log information, etc. For example, the notification message includes a start time and a participation place of an event that a user needs to participate in, the processor analyzes the notification message, determines the start time and the participation place, and obtains a current time and a current position of the electronic device, and if the position is within a specified range of the reference place and the start time is within a specified time range, it is determined that a scene type of a current scene is a scene type corresponding to the event. For example, if the event is a meeting, the determined scene type is a meeting type. The specified time range includes a start time and an end time, the time difference between the start time and the start time of the event is a first difference, the first difference may be ± M, the M may be a relatively small value, for example, 5 minutes, the end time is located after the start time of the event, and the time difference between the end time and the start time of the event is a second difference, the second difference may be N, for example, the N may be less than or equal to the holding duration corresponding to the event.

In addition, the duration parameter may also be set according to the holding duration corresponding to the analyzed event, for example, the duration parameter is set as the holding duration.

In one embodiment, if there are a plurality of determined scenes, the priority of each scene is determined, and the scene with the highest priority is used as the current scene. For example, a small group meeting is held at an exhibition hall, and two scenes, namely the exhibition hall and the meeting, may be determined.

Specifically, the plurality of scenes are sorted according to the priority of each scene to obtain the priority order of the plurality of scenes.

After the priority of each scene is obtained, the execution sequence of the scenes is sequenced according to the priority of the scenes. As an embodiment, the higher the priority, the higher the execution order of the scenes. As another embodiment, the execution order of the scenes with higher priority may be set to be later. It is also possible that some scenes are sorted according to priority and some other scenes are randomly sorted.

For example, suppose that the scenes corresponding to the scene trigger conditions are respectively scene a, scene B, scene C, scene D and scene E, and the priorities of the four scenes are that the priority of scene a is J1, the priority of scene B is J3, the priority of scene C is J4, the priority of scene D is J2, and the priority of scene E is J5. The priority is, in order from high to low: j1 J2, J3, J4, J5. That is, scene a has the highest priority, followed by scene D, then scene B, scene C, and scene E in that order. Then, the 5 scenes may be sorted according to a policy that the execution order of the scenes with higher priority is earlier, and the obtained priority order is: scene a > scene D > scene B > scene C > scene E. Thus, the current scene is determined to be scene a.

S1003: and determining the target electrochromic cover plate from the first electrochromic cover plate and the second electrochromic cover plate according to the scene information.

After the scene information is acquired, a coloring policy corresponding to the scene information may be determined, where the coloring policy is used to indicate devices in the camera and the flash that need to be colored. For example, as shown in table 1:

TABLE 1

Type of scene	Coloring strategy	Remarks to note
			Type 1 and type 2	Strategy 1	Disabled camera
Type 3 and type 4	Strategy 2	Disable flash lamp
			Type 5	Strategy 3	Disabling a camera and flash

Therefore, according to the corresponding relation, the coloring strategy corresponding to the current scene information can be found, and the target electrochromic cover plate can be determined from the first electrochromic cover plate and the second electrochromic cover plate according to the coloring strategy. For example, if the current scene information is type 1, the determined target electrochromic cover is the first electrochromic cover.

In one embodiment, the target electrochromic cover may be determined according to the electric wave signal. Specifically, the electrical wave signal includes an indicator parameter, and the processor determines the target electrochromic cover plate according to the indicator parameter. In some embodiments, the indication parameters include a first parameter, a second parameter, and a third parameter, and if the processor receives the first parameter, the processor determines that the target electrochromic overlay is a first electrochromic overlay, if the processor receives the second parameter, the processor determines that the target electrochromic overlay is a second electrochromic overlay, and if the processor receives the third parameter, the processor determines that the target electrochromic overlay is the first electrochromic overlay and the second electrochromic overlay.

For example, the parameters carried in the electrical wave signal received by the electronic device include three formats: the camera and flash are prohibited in this area (e.g., 0xf 1); the flash lamp is prohibited in the area (such as 0xf 2); the camera (e.g. 0xf 3) is forbidden to be used in this area, i.e. 0xf1 is the third parameter, 0xf2 is the second parameter, and 0xf3 is the first parameter.
