Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0035] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0036] In the description of this application, it should be understood that the terms "longitudinal", "lateral", "length", "upper", "lower", "front", "rear", "inner", "outer", "clockwise", "counterclockwise", "axial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] First, the terms used in this application will be explained to facilitate understanding by those skilled in the art:

[0039] Image sensor: Also known as a camera sensor, in a digital camera, the image sensor functions similarly to film in a traditional camera. Image sensors are generally divided into two types: charge-coupled device (CCD) and complementary metal-oxide-semiconductor (CMOS) devices.

[0040] The general workflow of a CMOS device is as follows: it senses an optical signal and converts it into an electrical signal; then, it amplifies and converts the electrical signal into an analog signal to form a digital signal matrix (i.e., image data); next, it performs image processing (Image Signal Processor, ISP) on the digital signal matrix to obtain the processed image data; finally, it compresses and stores the processed image data.

[0041] Among them, the CMOS camera module (CCM) is one of the mainstream camera modules used in terminals. It mainly consists of a lens, a voice coil motor, an infrared filter, an image sensor, a digital signal processor (DSP), and a flexible printed circuit board (FPC).

[0042] Polarized light, also known as plane-polarized light or linearly polarized light, is light whose plane of vibration is limited to a fixed direction. Light is an electromagnetic wave, and the plane formed by the direction of vibration of the electromagnetic wave and the direction of propagation of the light wave (i.e., the direction of light propagation) is called the plane of vibration.

[0043] Electromagnetic waves are transverse waves. The vibration direction of the light wave vector of a transverse wave is perpendicular to the direction of light wave propagation. On a plane perpendicular to the direction of light wave propagation, it can vibrate in any direction. Natural light vibrates uniformly in all directions and is unpolarized light. Natural light can be changed into light with a certain vibration direction after passing through a polarizer. This is because there is a certain characteristic direction in the polarizer (called the polarization direction), which allows light rays with vibration directions parallel to the polarization direction to pass through, while filtering out light rays with vibration directions perpendicular to the polarization direction.

[0044] Polarizer and Analyzer: The first polarizer P1 through which natural light passes can be called the polarizer, which converts natural light into polarized light. Since the human eye cannot distinguish between positively polarized light and negatively polarized light, a second polarizer P2 is needed to check for polarization. Rotating P2, when the polarization direction of P2 is parallel to the plane of vibration of the polarized light, the polarized light can pass through smoothly, and brighter light shines behind P2. When the polarization direction of P2 is perpendicular to the plane of vibration of the polarized light, the polarized light cannot pass through, and the area behind P2 becomes darker. This second polarizer P2, used to distinguish polarized light, is called the analyzer.

[0045] Based on the characteristics of the polarizer and analyzer described above, this application provides an information input system, method, and apparatus. In this application, an electronic device, a connecting component, and an input device are connected sequentially. A polarizer and an analyzer are provided between the photosensitive layer of the image sensor in the electronic device and the light-emitting unit of the connecting component. The rotation angle of the polarizer is related to the input signal of the input device. Thus, when the input signal of the input device is different, the rotation angle of the polarizer is different. The light emitted by the light-emitting unit becomes polarized light with different vibration directions (or vibration planes) after passing through polarizers with different rotation angles. The polarized light with different vibration directions passes through the analyzer and enters the photosensitive layer of the electronic device. The electronic device can identify the polarized light through the photosensitive layer and recognize the input information of the input device. Therefore, information input of the electronic device is realized.

[0046] As can be seen, the information input system provided in this application does not require the data interface of the electronic device or the display screen of the electronic device, and can be applied to a variety of electronic devices, especially electronic devices with no data interface or few data interfaces and small display screens.

[0047] The information input system, method, and device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0048] refer to Figures 1-2 , Figure 1 Schematic diagram of the information input system provided in the embodiments of this application Figure 1 , Figure 2 Schematic diagram of the information input system provided in the embodiments of this application Figure 2 .

[0049] like Figure 1 and Figure 2 As shown, the information input system includes:

[0050] Electronic device 10, the electronic device 10 includes an image sensor 11 having a photosensitive layer 111 disposed thereon;

[0051] The connection component 20 is detachably connected to the electronic device 10, and the connection component 20 includes a light-emitting unit 21.

[0052] Input device 30, which is detachably connected to connection assembly 20;

[0053] Polarizer 40 and analyzer 50;

[0054] In this configuration, with the electronic device 10, the connection component 20, and the input device 30 connected in sequence, the polarizer 40 and the analyzer 50 are located between the light-emitting unit 21 and the photosensitive layer 111, and the light emitted by the light-emitting unit 21 passes through the polarizer 40 and the analyzer 50 and enters the photosensitive layer 111; the rotation angle of the polarizer 40 is related to the input signal of the input device 30, so that the polarized light entering the photosensitive layer is different when the input signal of the input device 30 is different.

[0055] The rotation angle of the polarizer 40 is related to the input signal of the input device 30. The rotation angle of the polarizer 40 corresponds one-to-one with the input signal of the input device 30. When the input signal of the input device 30 is different, the rotation angle of the polarizer 40 is different. Thus, the electronic device 10 can accurately identify the input signal of the input device 30 based on the polarized light sensed by the photosensitive layer 111.

[0056] In this embodiment, when the electronic device 10, the connection component 20, and the input device 30 are connected in sequence, during the information input process: the input device 30 generates an input signal, and the polarizer 40 rotates by a rotation angle associated with the input signal, that is, the rotation angle corresponding to the input signal; the light emitted by the light-emitting unit 21 in the connection component 20 becomes polarized light after passing through the rotated polarizer 40, and the polarized light is identified by the analyzer 50 and then enters the photosensitive layer 111, where it is sensed by the photosensitive layer 111.

[0057] The angle of the analyzer 50 can be fixed, that is, the polarization direction of the analyzer 50 can be fixed. Therefore, when the polarizer 40 is rotated at different angles, the amount of light emitted by the light-emitting unit 21 that reaches the photosensitive layer 111 after passing through the rotated polarizer 40 and the fixed-angle analyzer 50 is different. When the polarization direction of the polarizer 40 after rotation is parallel to the polarization direction of the analyzer 50, the polarized light emitted by the light-emitting unit 21, after passing through the rotated polarizer 40, can completely pass through the analyzer 50 and reach the photosensitive layer 111. When the polarization direction of the polarizer 40 after rotation is perpendicular to the polarization direction of the analyzer 50, the polarized light emitted by the light-emitting unit 21, after passing through the rotated polarizer 40, cannot pass through the analyzer 50 and reach the photosensitive layer 111. When the polarization direction of the polarizer 40 after rotation is between parallel and perpendicular to the polarization direction of the analyzer 50, the polarized light emitted by the light-emitting unit 21, after passing through the rotated polarizer 40, can partially pass through the analyzer 50 and reach the photosensitive layer 111. Therefore, the electronic device can identify the rotation angle of the polarizer 40 based on the polarized light sensed by the photosensitive layer 111, and then determine the input signal of the input device 30 based on the correlation between the rotation angle of the polarizer 40 and the input signal of the input device 30. Thus, by utilizing the principle of polarized light, the input device 30 can input information to the electronic device 10 through the connection component 20 with the light-emitting unit 21.

[0058] from Figure 1 It can be seen that the information input system provided in this application has the following advantages: 1. Simple structure and low cost; 2. Compared with connecting input devices via wireless signals such as Bluetooth and wireless networks, the information input system uses a connecting component to connect the input device and inputs light signals to the electronic device through a stable light source, which improves the stability of information input; 3. Compared with connecting input devices via a data interface, the information input system does not need to occupy the data interface of the electronic device, and is especially suitable for electronic devices with few or no data interfaces; 4. Compared with a virtual keyboard, the information input system does not need to occupy the display screen of the electronic device and has no impact on the display effect of the electronic device, and is especially suitable for electronic devices with small screens.

[0059] In one example, electronic device 10 is, for example, a mobile phone, tablet computer, or other device with an image sensor.

[0060] In one example, input device 30 is, for example, a keyboard, mouse, gamepad, etc.

[0061] In one example, the light-emitting unit 21 may be a light-emitting component such as a light bulb, a light-emitting diode (LED), a liquid crystal display (LCD), or a digital tube built into the connection component 20.

[0062] In one example, the connecting component 20 can be a flexible printed circuit (FPC), and the light-emitting unit 21 can be disposed on the flexible printed circuit, making the connecting component 20 easy to store and fold, thus improving the user experience. Similarly, the input device 30 can also be made of flexible materials. Flexible printed circuit boards, also known as flexible circuit boards or flexible circuit boards, possess characteristics such as light weight, thinness, and the ability to be freely bent and folded.

[0063] In some embodiments, such as Figure 2 As shown, the polarizer 40 is disposed in the connecting assembly 20.

[0064] In this embodiment, in the connection assembly 20, the light emitted by the light-emitting unit 21 is converted into polarized light after passing through the polarizer 40. When the connection assembly 20 is detachably connected to the input device 30, the connection between the connection assembly 20 and the input device 30 can be electrical. The polarizer 40 is disposed in the connection assembly 20 so that the driving component (not shown in the figure) in the connection assembly 20 can control the polarizer 40 to rotate by a rotation angle associated with the input signal when it receives the input signal from the input device 30.

[0065] Optionally, the polarizer 40 can also be disposed in the image sensor 11. When the polarizer 40 is disposed in the image sensor 11, the analyzer 50, used to identify the polarized light emitted by the polarizer 40, is also disposed in the image sensor 11. To control the rotation of the polarizer 40, the electronic device 10, the connecting assembly 20, and the input device 30 can be electrically connected, so that the electronic device 10 controls the rotation of the polarizer 40 by a rotation angle corresponding to the input signal.

[0066] In some embodiments, such as Figure 2 As shown, the analyzer 50 is disposed in the image sensor 11.

[0067] In this embodiment, since the angle of the polarizer 50 can be controlled to remain constant, the polarizer 50 can be disposed in the image sensor 11. The polarizer 50 disposed in the image sensor 11 can block all or part of the photosensitive layer 111. When the polarizer 50 blocks all of the photosensitive layer 111, the electronic device 10 can identify the input signal of the input device 30 based on the polarized light sensed by the entire area of ​​the photosensitive layer 111; when the polarizer 50 blocks part of the photosensitive layer 111, the electronic device can identify the input signal of the input device 30 based on the polarized light sensed by the part of the photosensitive layer 111. Thus, by disposing of the polarizer 50 in the image sensor 11, the polarizer 50 can accurately block the photosensitive layer 111, improving the accuracy of the electronic device 10 in identifying the input signal of the input device 30.

[0068] Optionally, the analyzer 50 can also be disposed in the connection assembly 20. When the analyzer 50 is disposed in the connection assembly 20, since the analyzer 50 is used to identify the polarized light emitted from the polarizer 40, the polarizer 40 also needs to be disposed in the connection assembly 20. By disposing of the analyzer 50 in the connection assembly 20, when the connection assembly 20 is not connected to the electronic device 10, the analyzer 50 will not affect the imaging quality of the electronic device 10; when the electronic device 10, the connection assembly 20, and the input device 30 are connected in sequence, the analyzer 50 can be used to assist in the information input of the electronic device 10.

[0069] In some embodiments, Figure 3 A schematic diagram of the structure of the image sensor provided in the embodiments of this application. Figure 1 ,like Figure 3 As shown, the number of analyzers 50 is at least one, wherein, Figure 3 Taking multiple polarizers 50 as an example, each polarizer 50 is correspondingly provided with at least one photosensitive unit 1111 in the photosensitive layer 111. Thus, by providing a polarizer 50 corresponding to at least one photosensitive unit 1111 in the photosensitive layer 111, the accuracy of the photosensitive layer 111 in sensing polarized light is improved.

[0070] In this embodiment, in the image sensor 11, multiple photosensitive units 1111 in the photosensitive layer 111 sense light signals and convert them into electrical signals, which are then converted into pixel values ​​of pixels in the image. A polarizer 50 can be provided for at least one photosensitive unit 1111 in the image sensor 11, so that the polarized light sensed by at least one photosensitive unit 1111 is different when the rotation angle of the polarizer 40 is different, thereby improving the accuracy and reliability of the photosensitive layer 111 in sensing polarized light.

[0071] As an example, such as Figure 3 As shown, Figure 3Taking an array of multiple photosensitive units 1111 as an example, the photosensitive layer 111 is represented by a shaded pattern, and the analyzer 50 is shown as a shaded pattern. An analyzer 50 can be provided for each photosensitive unit 1111. R, B, Gr, and Gb represent photosensitive units that sense red, blue, and green light respectively (where Gr and Gb represent different shades of green).

[0072] In some embodiments, such as Figure 4 As shown, Figure 4 A schematic diagram of the structure of the image sensor 11 provided in the embodiments of this application. Figure 2 When the analyzer 50 is disposed in the image sensor 11, the image sensor includes: a microlens layer 112, and the analyzer 50 is located between the microlens layer 112 and the photosensitive layer 111.

[0073] In this embodiment, the polarized light emitted by the polarizer 40 enters the microlens layer 112, is converged by the microlens layer 112, enters the analyzer 50, and after being detected by the analyzer 50, reaches the photosensitive layer 111. Thus, the photosensitive layer 111 can distinguish the intensity of the polarized light.

[0074] In some embodiments, such as Figure 4 As shown, the image sensor 11 further includes a filter layer 113, which is located between the microlens layer 112 and the photosensitive layer 111. A polarizer 50 is located between the microlens layer 112 and the filter layer 113, or, alternatively, between the filter layer 113 and the photosensitive layer 111. Figure 4 Taking the polarizer 50 located between the microlens layer 112 and the filter layer 113 as an example, in the case where the image sensor 11 includes the filter layer 113, various configuration schemes for the polarizer 50 are provided, so that the polarized light identified by the polarizer 50 reaches the photosensitive layer 111.

[0075] In some embodiments, the image sensor 11 is disposed in the camera module of the electronic device 10. When the connecting component 20 is connected to the electronic device 10, one side of the connecting component 20 covers the outside of the camera module and is fixed relative to the camera module.

[0076] In the electronic device 10, the camera module may include a camera lens assembly and an image sensor 11. One side of the connecting component 20 is covered outside the camera module and fixed relative to the camera module. The connecting component 20 may also be covered outside the camera lens assembly and fixed relative to the camera lens assembly.

[0077] In this embodiment, one side of the connecting component 20 is covered outside the camera module and fixed relative to the camera module, which can improve the stability of the connection between the connecting component 20 and the electronic device 10. It can also ensure that the light emitted by the connecting component 20 can enter the camera module of the electronic device 10 and be sensed by the photosensitive layer 111 in the image sensor 11, thereby improving the stability and reliability of the information input of the electronic device 10.

[0078] As an example, Figure 5 An example diagram of an information input system provided in an embodiment of this application. Figure 5 In the middle, input device 30 ( Figure 5 (Taking the keyboard as an example) it is connected to the electronic device 10 via the connecting component 20. Figure 5 (Taking a mobile phone as an example) The connection component 20 is attached to the camera lens assembly 12 of the electronic device 10, covering the camera lens assembly 12. When the user inputs information via the keyboard, the polarizer rotates by a corresponding angle. The light emitted by the light-emitting unit passes through the polarizer and becomes polarized light. After being identified by the analyzer, it reaches the photosensitive layer. In this way, the input information from the keyboard can be determined based on the polarized light sensed by the photosensitive layer.

[0079] like Figures 1-2 As shown, this application embodiment also provides a connection component 20, which is used for detachable connection with electronic device 10 and input device 30. The connection component 20 includes: a light-emitting unit 21; wherein, when electronic device 10, connection component 20 and input device 30 are connected in sequence, the light emitted by light-emitting unit 21 passes through polarizer 40 and analyzer 50 and enters the photosensitive layer 111 of image sensor 11 of electronic device 10. The rotation angle of polarizer 40 is associated with the input signal of input device 30 so that the polarized light entering photosensitive layer 111 is different when the input signal of input device 30 is different.

[0080] In some embodiments, such as Figure 2 As shown, a polarizer 40 is provided inside the connecting component 20.

[0081] In some embodiments, the connection component includes a polarizer and a polarizer.

[0082] The implementation principle and technical effects of the connection component provided in this application embodiment can be referred to the connection component in the information input system provided in the foregoing embodiment, and will not be repeated here.

[0083] like Figure 4 As shown, this application embodiment also provides an image sensor 11, including: a photosensitive layer 111, a microlens layer 112, and at least one polarizer 50. For example... Figures 1-2As shown, when the electronic device 10 where the image sensor 11 is located, the connection component 20 provided in the above embodiment, and the input device 30 are connected in sequence, the light emitted by the light-emitting unit 21 in the connection component 20 passes through the polarizer 40 and the analyzer 50 and enters the photosensitive layer 111.

[0084] In some embodiments, such as Figure 3 As shown, each analyzer 50 is configured corresponding to at least one photosensitive unit 1111 in the photosensitive layer 111.

[0085] In some embodiments, such as Figure 4 As shown, the analyzer 50 is disposed between the microlens layer 112 and the photosensitive layer 111.

[0086] In some embodiments, such as Figure 4 As shown, the image sensor 11 also includes a filter layer 113 located between the microlens layer 112 and the photosensitive layer 111; the polarizer 50 is located between the microlens layer 112 and the filter layer 113, or the polarizer 50 is located between the filter layer 113 and the photosensitive layer 111. Figure 4 Taking the polarizer 50 located between the microlens layer 112 and the filter layer 113 as an example.

[0088] This application also provides an electronic device, which includes an image sensor as provided in any of the foregoing embodiments. For example, the electronic device may be a camera, a mobile phone, a computer, etc. Thus, the electronic device can achieve information input through the image sensor, connection components, polarizer, and analyzer, improving the stability and reliability of information input and enhancing the user experience.

[0089] This application also provides an information input method. This method can be applied to the information input system provided in any of the foregoing embodiments.

[0090] refer to Figure 6 , Figure 6 Flowchart of the information input method provided in the embodiments of this application Figure 1 .like Figure 6 As shown, the information input method provided in this application embodiment may include:

[0091] S601 generates input signals through input devices.

[0092] In this embodiment, an input signal can be generated in response to a user's input operation on the input device. For example, if the input device is a keyboard, an input signal can be generated in response to a user clicking a key on the keyboard. Or, if the input device is a mouse, corresponding input signals can be generated in response to a user's left-click, right-click, double-click, scroll, or other operations on the mouse.

[0093] S602 controls the polarizer to rotate to the target angle corresponding to the input signal.

[0094] The rotation angle of the polarizer is related to the input signal of the input device. This relationship can be described as a one-to-one correspondence between the polarizer's rotation angle and the input signal; different input signals result in different rotation angles for the polarizer.

[0095] In this embodiment, in the information input system, an input signal from an input device can be received via a drive unit connected to the polarizer, and the polarizer can be controlled to rotate to a target angle corresponding to the input signal in response to the input signal. Specifically, when the polarizer is located in a connecting assembly, the drive unit connected to the polarizer in the connecting assembly can control the polarizer to rotate to the target angle; when the polarizer is located in an electronic device, the drive unit connected to the polarizer in the electronic device can control the polarizer to rotate to the target angle; furthermore, when the polarizer is located in an image sensor of an electronic device, the drive unit connected to the polarizer in the image sensor can control the polarizer to rotate to the target angle. The drive unit can be a drive motor or other structure capable of performing a driving function.

[0096] S603 controls the light-emitting unit in the connection assembly to emit light. The light emitted by the light-emitting unit passes through the polarizer and analyzer rotated to the target angle and then reaches the photosensitive layer of the image sensor.

[0097] In this embodiment, the light-emitting unit can be controlled to emit light by a driving component in the connecting assembly. The detachable connection between the connecting assembly and the input device can be an electrical connection. The connecting assembly can control the light-emitting unit to emit light upon receiving an input signal from the input device, or it can control the light-emitting unit to emit light while detachably connected to the input device. After the polarizer rotates to the target angle, the light emitted by the light-emitting unit passes through the polarizer, forming polarized light. After being identified by the analyzer, the polarized light enters the photosensitive layer of the image sensor of the electronic device.

[0098] S604 acquires image data through the photosensitive layer.

[0099] When the polarizer is rotated at different angles, the vibration direction of the polarized light emitted from the polarizer varies. Since the polarization direction of the analyzer remains unchanged, polarized light with different vibration directions undergoes different degrees of filtering (i.e., identification) at the analyzer, resulting in different amounts of light passing through the analyzer. When the vibration direction of the polarized light is consistent with the polarization direction of the analyzer, all the polarized light can pass through the analyzer; when the vibration direction of the polarized light is perpendicular to the polarization direction of the analyzer, the polarized light cannot pass through the analyzer; when the vibration direction of the polarized light is between the polarization direction of the analyzer and the direction perpendicular to that polarization direction, some of the polarized light can pass through the analyzer, while some cannot.

[0100] Therefore, when the input signal of the input device is different, the polarizer rotates to a different target angle, the polarization direction of the polarized light emitted by the polarizer is different, the number of rays of polarized light with different vibration directions passing through the analyzer is different, and thus the number of rays of polarized light sensed by the sensing layer is different.

[0101] In this embodiment, image data can be formed based on the sensing layer's perception of polarized light. This involves converting the optical signal into an electrical signal, amplifying the electrical signal, performing digital-to-analog conversion, and forming a digital signal matrix, which in turn generates the image data. Different input signals result in different image data generated based on the sensing layer's perception of polarized light, allowing the input signal of the input device to be determined subsequently based on this image data.

[0102] S605 controls electronic devices to respond based on image data.

[0103] In this embodiment, since the image data differs depending on the input signal, the electronic device can be controlled to respond based on the image data. This includes controlling the electronic device to respond to input signals from the input device, such as displaying text corresponding to the input signal or executing device operations indicated by the input signal, such as switching, closing, or page scrolling.

[0104] In one possible implementation, since the image data is affected by the target angle of the polarizer's rotation, and this target angle is correlated with the input signal, the target angle can be determined based on the image data. Based on the correlation between the target angle and the input signal, the input signal of the input device can be determined, and the electronic device can be controlled to respond to this input signal. This improves the accuracy of the electronic device's response.

[0105] In addition, a correspondence between image data and the response operation of electronic devices can be established in advance. Based on this correspondence, the response operation corresponding to the image data can be determined, and the electronic device can be controlled to execute the response operation.

[0106] In this embodiment, by utilizing a connection component, a polarizer, and an analyzer, the image sensor of the electronic device perceives different polarized light when different input signals are input, resulting in different image data. Based on this image data, the electronic device can be controlled to respond. This achieves information input for the electronic device, improves the stability and accuracy of information input, and eliminates the need to occupy the electronic device's display screen and data interface, effectively enhancing the user experience.

[0107] refer to Figure 7 , Figure 7 Flowchart of the information input method provided in the embodiments of this application Figure 2 .like Figure 7 As shown, the information input method provided in this application embodiment may include:

[0108] S701 generates input signals through input devices.

[0109] S702 controls the polarizer to rotate to the target angle corresponding to the input signal.

[0110] S703 controls the light-emitting unit in the connection assembly to emit light. The light emitted by the light-emitting unit passes through the polarizer and analyzer, which are rotated to the target angle, and then reaches the photosensitive layer of the image sensor.

[0111] S704 acquires image data through the photosensitive layer.

[0112] The implementation principles and technical effects of S701-S704 can be referred to in the aforementioned embodiments, and will not be repeated here.

[0113] S705 determines light intensity information based on image data.

[0114] In this embodiment, because the input signals from the input devices differ, the rotation angle of the polarizer varies. This difference in rotation angle results in different amounts of polarized light passing through the analyzer, leading to varying intensity of polarized light perceived by the photosensitive layer. The intensity of polarized light perceived by the photosensitive layer can be determined based on the image data generated from the perception of polarized light by the photosensitive layer.

[0115] The image data is a digital signal matrix; therefore, it includes signal values ​​corresponding one-to-one with multiple photosensitive units. The larger the signal value, the stronger the intensity of the polarized light sensed by the photosensitive unit. Based on this, determining light intensity information from image data can be achieved in several possible ways:

[0116] In one possible implementation, there is one polarizer, which is associated with a photosensitive unit in the photosensitive layer. This photosensitive unit is referred to as the target photosensitive unit. The signal value corresponding to the target photosensitive unit can be obtained from the image data; this signal value corresponds to light intensity information. Furthermore, by using only one polarizer, the electronic device can be controlled to respond based on the intensity of the polarized light sensed by the photosensitive unit corresponding to that polarizer, thus improving the accuracy of information input to the electronic device.

[0117] In another possible implementation, there are multiple analyzers, each corresponding to a different target photosensitive unit in the photosensitive layer. Considering that the analyzers may have errors, the signal values ​​corresponding to the multiple target photosensitive units can be obtained from the image data, and the signal values ​​corresponding to the multiple target photosensitive units can be fused to obtain light intensity information, thereby improving the accuracy of the light intensity information.

[0118] Optionally, fusing the signal values ​​corresponding to multiple target photosensitive units to obtain light intensity information may include: averaging the signal values ​​corresponding to multiple target photosensitive units to obtain an average value, and determining the light intensity information as the information corresponding to the average value; or, performing a weighted operation on the signal values ​​corresponding to multiple target photosensitive units to obtain a weighted result, and determining the light intensity information as the information corresponding to the weighted result.

[0119] In another possible implementation, the number of image data sets is multiple. During the process of the input device generating the input signal and the polarizer rotating to the target angle corresponding to the input signal, the photosensitive layer can acquire image data multiple times, resulting in multiple sets of image data. These multiple sets of image data can be fused to obtain light intensity information, thereby improving the accuracy of the light intensity information.

[0120] Optionally, fusing multiple sets of image data to obtain light intensity information may include: for each set of image data, obtaining signal values ​​corresponding to multiple target photosensitive units from the image data, weighting or averaging the signal values ​​corresponding to multiple target photosensitive units to obtain the light intensity value corresponding to the image data, and weighting or averaging the light intensity values ​​corresponding to multiple sets of image data to obtain light intensity information.

[0121] S706 determines the target angle based on light intensity information.

[0122] In this embodiment, based on Malus's law, the intensity of polarized light passing through the polarizer and analyzer is related to the angle between their optical axes. Therefore, the angle between the optical axes of the polarizer and analyzer can be determined based on the intensity of the reference polarized light and the intensity determined from the image data. Since the polarization direction of the polarizer is fixed, this angle can be added to the polarization direction of the polarizer (which reflects the angle of the polarizer's optical axis) to obtain the target angle to which the analyzer has rotated. This improves the accuracy of the target angle.

[0123] In this context, the reference polarized light is the polarized light emitted by the light-emitting unit when the optical axes of the polarizer and analyzer are parallel (i.e., the polarization direction of the polarizer is parallel to the polarization direction of the analyzer), after passing through the polarizer and analyzer. Since the reference polarized light is the polarized light emitted by the light-emitting unit when the optical axes of the polarizer and analyzer are parallel, after passing through the polarizer and analyzer, it is equivalent to the polarized light completely passing through the analyzer, and the intensity of the polarized light sensed by the sensing layer of the image sensor is at its maximum.

[0124] Alternatively, the formula for determining the angle between the optical axes of the polarizer and the analyzer can be expressed as:

[0125] I = I0cos 2 θ

[0126] Where I0 represents the intensity information of the reference polarized light, I represents the intensity information determined based on image data, and θ represents the optical axis angle. After obtaining the optical axis angle, if the optical axis of the polarizer is parallel to the optical axis of the analyzer without rotation, then the target angle to which the analyzer has rotated can be determined as the optical axis angle.

[0127] S707 determines control information based on the target angle and controls the electronic device to respond based on the control information, wherein the target angle and the control information are correlated.

[0128] The input signal from the input device is correlated with the rotation angle of the polarizer, and the input signal from the input device is correlated with the control information. Therefore, the target angle is correlated with the control information. This correlation can be understood as a correspondence; furthermore, to improve the accuracy of the information input, i.e., to improve the accuracy of the control information, the correlation can be understood as a one-to-one correspondence.

[0129] As an example, taking a keyboard with 104 keys as the input device, when each key is pressed, the polarizer rotates so that polarized light at a specific angle corresponding to the pressed key enters the camera lens assembly of the electronic device. The keyboard has 104 keys, and the polarization angle ranges from 0° to 90°, starting from 0°, with each 0.5° interval corresponding to a key. This allows different input signals from the input device to correspond to different angles of polarized light; that is, different input signals correspond to different target angles, and different target angles correspond to different control information.

[0130] In this embodiment, the input signal corresponding to the target angle can be determined based on the correlation between the input signal of the input device and the rotation angle of the polarizer; the control information can be determined based on the correlation between the input signal corresponding to the target angle and the control information; and then, the electronic device can be controlled to respond according to the control information. For example, if the input signal corresponding to the target angle is the signal for inputting the Enter key, then the control information can be determined to be an instruction to instruct the electronic device to perform the Enter operation; or, if the input signal corresponding to the target angle is the signal for inputting the character "Q", then the control information can be determined to be an instruction to instruct the electronic device to display the character "Q".

[0131] In this embodiment, by utilizing a connecting component, a polarizer, and an analyzer, the image sensor's perception layer of the electronic device can detect polarized light of different intensities when different input signals are input to the input device. Based on the intensity information of the polarized light, the target angle to which the polarizer should rotate is determined. According to the target angle, control information is determined, and the electronic device is controlled to respond based on the control information. In this way, information input of the electronic device is realized, the stability of information input is improved, and the accuracy of information input is ensured by utilizing the intensity and optical axis angle of the reference polarized light.
