In the above steps, the current driving type of the target vehicle includes, but is not limited to, automatic driving, manual driving, and the like.

In an alternative embodiment, the determining the target scene based on the current driving type includes determining that the target scene is a first type scene in which content displayed by the head-up display device needs to be fused with a real environment in which the target vehicle is located in a case where the driving type is manual driving, and determining that the target scene is a second type scene in which content displayed by the head-up display device does not need to be fused with the real environment in which the target vehicle is located in a case where the driving type is automatic driving.

In an alternative embodiment, before determining the target angle range corresponding to the target scene, the method further comprises determining content displayed by the head-up display device, determining that the target scene where the target vehicle is located is a first type scene when target type information is included in the content displayed by the head-up display device, wherein the content displayed by the head-up display device needs to be fused with a real environment where the target vehicle is located in the first type scene, and determining that the target scene where the target vehicle is located is a second type scene when the target type information is not included in the content displayed by the head-up display device, wherein the content displayed by the head-up display device does not need to be fused with the real environment where the target vehicle is located in the second type scene, and the target type information is fused with a driving scene.

In an alternative embodiment, determining the target angle range corresponding to the target scene includes determining that the target angle range is a first angle range when the target scene is a first type scene, wherein content displayed by the head-up display device needs to be fused with a real environment where the target vehicle is located in the first type scene, and determining that the target angle range is a second angle range when the target scene is a second type scene, wherein content displayed by the head-up display device does not need to be fused with the real environment where the target vehicle is located in the second type scene, and the first angle range is smaller than the second angle range.

In the above steps, in the first type of scene, the first angle range is smaller, so that the picture displayed by the sun shield can be fused with the current scene, and in the second type of scene, the second angle range is larger, so that the personalized requirements of users (such as playing movies, video conferences and the like) can be met, and the comfort level is improved.

Wherein the first angular range is smaller than the second angular range, i.e. the maximum value in the first angular range is smaller than the maximum value in the second angular range.

In an optional embodiment, the target object may also manually adjust the display panel angle and the height of the virtual image through interaction modes such as a control interface or voice in the vehicle, and the target object may perform user-defined setting of the HUD virtual image height (or the display panel angle) according to personal preference, and the system may perform automatic adjustment according to the memory function in combination with the last setting through ID binding, face recognition, iris recognition, and other technologies. Optionally, a HUD virtual image height, display panel angle setting options or shortcuts may be added to the vehicle's central control system. The settings may be absolute height values (e.g., vertical distance from the ground to the virtual image) or relative height values (e.g., vertical distance from the eye position of the target object to the virtual image) and display panel roll-over angles.

In an alternative embodiment, controlling the sun shield to open and close within the target angle range comprises obtaining position information of eyes of a target object, determining a target opening and closing angle of the sun shield within the target angle range based on the position information of the eyes of the target object, and controlling the sun shield to open to the target opening and closing angle so that the eyes of the target object are located within an eye box range.

In an alternative embodiment, acquiring the position information of the eyes of the target object comprises acquiring the position information of the eyes of the target object under a first condition, wherein the first condition comprises at least one of detecting that the position of the eyes of the target object deviates by more than a first threshold value, detecting that the time period of detecting that the position of the eyes of the target object deviates by more than a second threshold value, detecting that the position of a target seat changes, detecting that the position of a rearview mirror of the target vehicle changes, and detecting that the position of a steering wheel of the target vehicle changes.

In the above steps, the first threshold includes, but is not limited to, a first threshold in which the target object is shifted in the front-rear direction, a first threshold in which the target object is shifted in the up-down direction, a first threshold in which the target object is shifted in the left-right direction, the first threshold being set respectively according to actual scenes and target vehicle models, the first threshold including, but not limited to, 3 seconds, 5 seconds, etc., and the second threshold being set respectively according to actual scenes. The target seats include, but are not limited to, seats in a primary drive position. In the case where the angle of the sun visor cannot be adjusted so that the eyes are positioned within the range of the eye box based on the current eye position (for example, a person intentionally lies down or the head is lowered or lifted up to a large extent), the opening/closing angle of the sun visor may be adjusted to a limit value within the current angle range so as to minimize the distance between the eyes of the target subject and the range of the eye box.

In an alternative embodiment, acquiring the position information of the eyes of the target object comprises acquiring first position information of the eyes of the target object in a coordinate system of a target dimension, and determining the target opening and closing angle of the sun shield in the target angle range based on the position information of the eyes of the target object comprises determining the target opening and closing angle of the sun shield in the target angle range based on the first position information, wherein the coordinate system of the target dimension comprises one of a one-dimensional coordinate system, a two-dimensional coordinate system and a three-dimensional coordinate system.

In some embodiments, the visor has two shafts about which the visor rotates, i.e., the visor rotates back and forth, e.g., the visor rotates to angle α about a first shaft as shown in fig. 2, and the visor rotates about a second shaft, i.e., the visor rotates side-to-side.

For example, when the eye height is changed, the obtained eye position of the target object is the eye height (X-axis coordinate), the determined target opening/closing angle is the angle of forward/backward rotation, and the sun visor is controlled to automatically rotate around the first rotation axis to the target opening/closing angle. Fig. 3 is a second schematic diagram illustrating an open/close state change of a sun visor according to an embodiment of the present disclosure.

Under the condition that the left and right positions of eyes are changed, the obtained eye position of the target object is the position (Z-axis coordinate) of the eyes in the left and right direction, the determined target opening and closing angle is a left and right rotation angle, and the sun shield is controlled to automatically rotate around the second rotation shaft to the target opening and closing angle.

Under the condition that the height of eyes and the left and right directions are changed, the obtained eye positions of the target objects are the positions (X-axis coordinates and Z-axis coordinates) of the eyes in the height direction and the left and right directions, and the determined target opening and closing angles comprise a first target opening and closing angle (front and back rotating angle) and a second opening and closing angle (left and right rotating angle), and the sunshading board is controlled to automatically rotate to the first target opening and closing angle around the first rotating shaft and the sunshading board is controlled to automatically rotate to the second target opening and closing angle around the second rotating shaft.

Under the condition that the height of eyes, the left and right directions and the front and back directions are changed, the obtained eye positions of the target object are X-axis coordinates, Y-axis coordinates (the positions of eyes in the front and back directions) and Z-axis coordinates, and the determined target opening and closing angles comprise a first target opening and closing angle (front and back rotating angle) and a second opening and closing angle (left and right rotating angle), the sunshading board is controlled to automatically rotate around a first rotating shaft to the first target opening and closing angle, and the sunshading board is controlled to automatically rotate around a second rotating shaft to the second target opening and closing angle.

The following describes, in detail, how the sun visor is controlled to be opened to a target opening/closing angle according to the present disclosure:

Step one, starting or closing a vehicle according to a driver, and automatically opening and closing a HUD display panel (namely the target sun shield);

And step two, the opening and closing angle of the display panel, the height of the virtual image display picture and other relevant hardware are adjusted in linkage and real time.

In an alternative embodiment, when the target object is a driver of the target vehicle, and the detected position of the eyes of the target object exceeds a first threshold, or the detected position of the eyes of the target object exceeds a second threshold, or the detected position of the eyes of the target object exceeds the first threshold, and the detected position of the eyes of the target object exceeds the second threshold, the positions of the rearview mirror and the steering wheel of the target vehicle are adjusted together according to the position information of the eyes of the target object, for example, the rotation angles of the left rearview mirror and the right rearview mirror are adjusted, the distance between the steering wheel and the user is adjusted, and the like.

In the above steps, the system CAN acquire the start or close state of the vehicle in real time through the CAN bus of the vehicle or other applicable communication modes, and when the vehicle starts, the system receives a start signal, and when the vehicle closes, the system receives a close signal. When the system receives a vehicle starting signal, namely, the driver is judged to get on the vehicle, the system automatically opens the sun shield in the cab through the control device, so that the sun shield enters a working state. When the system receives a vehicle shut-off signal, i.e., determines that the driver has been getting off the vehicle, the system automatically retracts the sun visor to protect the device and provide more space. During the running of the vehicle, the system continuously monitors the vehicle state to prevent misoperation. If the system misjudges the vehicle status, for example, the vehicle is started but the driver is not getting on, the system will not trigger the operation of automatically opening and closing the sun visor in the cockpit. Alternatively, the driver can be identified to get on or off the vehicle by a sensor or a camera, and the sun shield can be automatically opened or closed. For example, a proximity sensor or a front-mounted camera is installed near the driver's seat for detecting the getting-on/off action of the driver or recognizing the driver's state. The HUD equipment is internally integrated with an opening and closing mechanism, so that the opening and closing state of the sun shield can be controlled. Alternatively, the driver's get-on and get-off actions can be predicted, determined, and monitored in real time by the distance between the driver and the vehicle using the driver status sensor. When the driver is close to the vehicle, the sensor can trigger a signal, and the automobile system triggers an opening and closing structure in the HUD according to the sensor signal. When a driver gets on and starts the vehicle, the sun shield can be automatically unfolded so that the driver can see the virtual image, and when the driver gets off, the sun shield can be automatically closed so as to avoid obstructing the sight of the driver. Optionally, the opening or closing operation of the sun visor is realized by other modes such as a key, voice and the like.

In the above steps, a high-precision eye tracking sensor is installed between the driver seat and the sun visor to monitor the eye position of the driver in real time. The height and sitting posture state of the driver's seat can be detected by integrating the seat height and sitting posture sensors. Physical characteristics of the driver (e.g., head position, height, etc.) may also be identified by a camera or an infrared sensor, while vehicle travel state information (e.g., speed, acceleration, etc.) may be obtained by a vehicle sensor. The HUD height (or display panel angle) adjusting system integrates an automatic display screen height (or display panel angle) adjusting function, and can automatically adjust according to eye movement tracking data. When a driver gets on or off a vehicle or adjusts the height of a seat or sitting posture, the system obtains the eye position of the driver in real time through an eye tracking sensor. The angle adjustment of the display panel (namely the sun visor) is linked with the adjustment of the equipment such as the seat, the rearview mirror, the steering wheel and the like. When the driver adjusts the seat height or changes the sitting posture, the height of the HUD virtual image (or the display panel angle) is also automatically adjusted, maintaining the optimal line of sight alignment with the eye box. When the angle of the display panel changes, the height of the picture changes, namely the lower viewing angle changes.

For example, the target opening and closing angle may be determined according to the target angle range and the position information of the eyes. For example, the target opening and closing angle may be determined directly from a correspondence between the eye position and the opening and closing angle within a target angular range, and the opening and closing angle may be determined by using a mathematical model, such as a polynomial fit or training a machine learning model from experimental data, and using the trained machine model, wherein the opening and closing angles determined under the first and second angular ranges are different.

In the embodiments of the present disclosure, image light emitted from the head-up display device HUD is reflected by the target sunshade plate and then is incident into the range of the eye box, and when both eyes of a user are located in the range of the eye box, a virtual image (or referred to as a virtual image screen, a HUD display screen, etc.) presented in front of the sunshade plate can be viewed. Fig. 4 is a schematic diagram three illustrating an opening and closing state change of a sun visor according to an embodiment of the present disclosure, as shown in fig. 4, a preset opening angle of the display panel (i.e., the foregoing sun visor) is determined first during automatic opening, where the preset opening angle of the display panel needs to satisfy that a driver's line of sight is aligned to a center position of the display panel, that is, a virtual image picture seen by a human eye is complete, on this basis, a picture height is finely adjusted, and when a line of sight position of the driver changes slightly during driving, the display panel performs angle fine adjustment, thereby adjusting a HUD eye box position, satisfying that a human eye can view a complete virtual image picture through the display panel, and a comprehensive picture display height ensures that a display effect is optimal. The adjustment of the visual angle under the virtual image, namely the adjustment of the height of the virtual image, can be realized by adjusting the opening and closing angle of the sun shield. The lower viewing angle is the included angle BAC between the horizontal line AB passing through the center of the eye box and the connecting line AC of the center of the eye box and the center of the virtual image. Changing the virtual image lower viewing angle can realize the change of the virtual image height. The lower viewing angle is negative when the virtual image center is lower than the center of the eye box, and positive when the virtual image center is higher than the center of the eye box, and can be also called as the upper viewing angle. The opening and closing mechanism adopts a smooth opening and closing mode so as to ensure that the opening and closing process can not influence the experience of a driver. When the HUD virtual image height (or the angle of the display panel) is adjusted, the system adopts a smooth transition mode, so that uncomfortable feeling of a driver caused by abrupt change is avoided. Optionally, in some cases, the driver may manually control the opening and closing state of the sun visor to meet specific requirements.

In the related art, through settling HUD equipment in integrated HUD system in the car top, image HUD equipment through the sunshading board, but the transmittance of sunshading board can't be adjusted, can't adapt to different driving scenes, has caused serious influence to driving safety even, to above-mentioned problem, does not appear suitable solution in the related art temporarily.

In this embodiment, a method for adjusting the transmittance of a sun visor operating on a terminal or a similar device is provided, which can solve the above-mentioned problems in the related art, and fig. 5 is a flowchart of a method for adjusting the transmittance of a sun visor according to an embodiment of the present disclosure, as shown in fig. 5, where the flowchart includes the following steps:

step S502, obtaining target running information of a target vehicle, target environment information of an environment where the target vehicle is located and target state information of a target object;

Step S504, adjusting the transmittance of the sun visor based on the target traveling information, the target environment information, and the target state information.

In the above steps, the material of the sun shield comprises but not limited to electrochromic glass materials (including but not limited to inorganic oxide electrochromic materials, polymer electrochromic materials and the like), and the electrochromic glass materials can realize reversible color change and transmittance change under the action of an electric field. And applying the electrochromic glass material to a glass panel of the target sunshade board of the HUD system to form the sunshade board made of electrochromic glass material. The target traveling information includes, but is not limited to, speed, acceleration, traveling direction of the vehicle, etc. vehicle state information including, but not limited to, traveling environment (e.g., road, parking lot, tunnel, etc.), light conditions (daytime, night, etc.), ambient light intensity, weather (foggy, rainy, snowy, etc.), etc., and the target object automatically adjusts transmittance of the sun visor according to road conditions, ambient light during use of the HUD, e.g., the target sun visor reduces transmittance when the daytime is sunny, reduces direct sunlight, ensures that information displayed by the HUD is clearly visible and is not disturbed by sunlight, and the target sun visor appropriately improves transmittance at night or in cloudy days, avoids the excessive brightness of content information displayed by the HUD from affecting the vision of the target object, and at the same time, intelligent driving assistance functions (e.g., adaptive cruise, etc.), Lane keeping, etc.), the target mask automatically adjusts the local transmittance, and the target object may also manually control the overall and local brightness of the target mask, control of the HUD image mode, zoom of HUD interface elements, etc. based on voice, gesture, and mobile phone connection; the target light shielding plate can also provide privacy protection when needed by being adjusted to be in a completely opaque state, prevent external personnel from peeping into the vehicle, can locally display a virtual cosmetic mirror, and can display the target object, the image and the image of the object in real time based on a high-definition camera arranged on the cabin or the copilot of the target object through a high-resolution display technology, facial images of other passengers. The target state information of the target object includes, but is not limited to, state information of the target object (i.e., driver or occupant), such as physical state data of the target object (e.g., angle of inclination of the target object's body, opening/closing condition of the target object's eyes, position of the target object's hands, etc., such as when the target object's eyes are open, angle of upper body half to vertical is greater than 20 degrees, hands are not placed on steering wheel, the target object may be resting or viewing needs exist, when the target object's eyes are open, angle of upper body half to vertical is around 5 degrees, and so on, The target object may have a driving requirement when the hand is placed on the steering wheel. In the above-described embodiments, by way of example, various sensors (including but not limited to light sensors, cameras, temperature sensors, weather sensors, vehicle sensors, etc.) may be integrated on the vehicle for collecting data regarding the environment, light conditions, vehicle status, and behavior of the target object. The data obtained from the sensors is collected and processed in real time (including, but not limited to, calculating solar altitude, light intensity, eye position of the target object, vehicle travel direction, vehicle speed, etc.).

Through the steps, as the environmental information can be obtained and the transmittance of the sun shield is adjusted according to the environmental information in combination with the target driving information and the target state information, the problem of safety reduction caused by the loss of the sun shield function when the sun shield in the related art realizes the HUD function can be solved, and the effect of considering the HUD function and the sun shield requirement is achieved.

In an alternative embodiment, the sun visor comprises a first area and a second area, the first area is used for shading light, the second area is used for reflecting and imaging image light rays emitted by the head-up display device, and adjusting the light transmittance of the sun visor based on the target running information, the target environment information and the target state information comprises adjusting the light transmittance of the first area and the second area based on the target running information, the target environment information and the target state information.

In the above steps, the method for partitioning the sun visor includes, but is not limited to, up-down partition, left-right partition, and the like, and optionally, the partition of the sun visor is not limited to two, and may be flexibly configured according to the position of the HUD system and the requirements in the vehicle, so as to achieve more accurate partitioning. Optionally, the HUD system further includes a user interface, and the HUD system allows the target object to manually adjust the transmittance of the whole or partial region of the target sun visor according to the requirement, so as to achieve the best sun-shading and HUD display effects.

In an alternative embodiment, adjusting the transmittance of the sun visor based on the target driving information, the target environment information and the target state information includes inputting the target driving information, the target environment information and the target state information into a target neural network model to obtain a target transmittance control instruction output by the target neural network model, wherein the target neural network model is a model with a transmittance control instruction prediction capability trained in advance, and adjusting the transmittance of the sun visor based on the illumination intensity of the environment where the target vehicle is currently located under the condition that the target transmittance control instruction is used for indicating to start a transmittance adjustment function.

In the above embodiments, the behavior of the target object may be predicted by correlating the behavior of the target object with sensor data using a machine learning model, including but not limited to a deep learning neural network, for example, the target object may consider opening a visor when sunlight is glare, the HUD system may bi-directionally communicate with the target object to ensure that the target object has ultimate control over automatic decisions, wherein the machine learning model is established based on pre-training the behavior of the target object and then imported into the HUD system.

In an alternative embodiment, adjusting the transmittance of the sun visor based on the intensity of the illumination currently applied to the target vehicle includes adjusting the transmittance of the first region to a preset value, and adjusting the transmittance of the second region to a target transmittance corresponding to the intensity of the illumination currently applied to the target vehicle according to a correspondence between the preset intensity of the illumination and the transmittance.

In an alternative embodiment, after adjusting the transmittance of the sun visor based on the illumination intensity of the environment where the target vehicle is currently located, the method further includes at least one of adjusting the brightness of the image source output in the head-up display device based on the adjusted transmittance, so that the contrast ratio between the virtual image of the sun visor after reflecting and imaging the image light emitted by the head-up display device and the real environment where the target vehicle is located and transmitted by the sun visor is smaller than a third threshold value, and calibrating and compensating the color value of the image source output in the head-up display device based on the adjusted transmittance, so that the display color of the virtual image of the sun visor after reflecting and imaging the image light emitted by the head-up display device meets a certain condition.

In the above steps, in order to ensure the display effect of the target sunshade screen, some screen corrections are performed, where the corrections include, but are not limited to, adjusting the brightness of the image source output in the HUD device, adjusting the color value of the image source output, or adjusting the brightness of the image source output in the HUD device and adjusting the color value of the image source output.

For example, when the transmittance of the sun visor decreases (i.e. the color gets deeper), the background brightness of the HUD virtual image gradually decreases, but the contrast of the HUD virtual image with respect to the background increases, which may lead to a potential high brightness glare risk, and in order to ensure the readability and safety of the HUD, the HUD system needs to correspondingly decrease the brightness of the HUD image source. When the transmittance of the target sunshade plate is reduced, the system automatically reduces the brightness of the HUD image source so as to ensure that the virtual image-environment contrast ratio under various backgrounds is consistent. This kind of linkage is adjusted and can be ensured that HUD picture display effect is stable under different transparencies to provide better user experience. In some embodiments, a plurality of brightness sensors (e.g., photoresistors, photodiodes, CCD cameras, CMOS cameras, photometers, etc.) are arranged on the target object side of the target sun visor, and the background brightness through electrochromic glass (i.e., the target sun visor) is calculated from the values of the plurality of sensors. Wherein the output luminance of the image source can be adjusted by a luminance change rate = pre-change electrochromic transmission luminance/post-change electrochromic transmission luminance, and a luminance change value = pre-change backlight luminance x luminance change rate of the image source. The image source includes a display panel (e.g., a liquid crystal display panel) and a backlight source, and the backlight source provides backlight to the display panel.

In some embodiments, the color output of the HUD display is automatically adjusted based on the change in transmittance of the electrochromic glazing, i.e., by monitoring the transmittance of the electrochromic glazing and the ambient light conditions in real time, the system can dynamically calibrate the output of the RGB image sources to maintain color accuracy and consistency. The gain of each color channel of the image source can be specifically adjusted to change the color (wherein, color distortion may occur after changing the backlight brightness, and correction by an algorithm is needed). The example is a new red channel value=original red channel value×r gain, a new green channel value=original green channel value×g gain, a new blue channel value=original blue channel value×b gain, where R gain, G gain, and B gain are gain factors determined by correcting for changes in transmittance, and the gain factors may be values greater than 1 (i.e., brightening) or greater than 0 and less than 1 (i.e., darkening), and the gain factors are determined based on actual product testing, calibration, laboratory experiment results, and red, green, blue (etc.) are adjusted to the same level by measuring different transmittances, for example:

Set up two HUD systems, left side places the HUD under 100% transmittance, and the right side sets up the HUD of x% transmittance.

1. The defined color red, yellow, green, blue, color patches were observed for 100% transmittance.

2. The color patch of the same color in the HUD screen at the right x% transmittance (e.g., 10-90%) is adjusted to be the same as the subjective and left HUD color and the color value is recorded.

3. Deriving a corresponding combination of input colors (colors defined in the first step) and output colors (colors recorded in the third step) (the input colors should include bright colors, dark colors, saturated colors and unsaturated colors.)

4. Calculating gain, gain = output color value/input color value

In some embodiments, the color values of the image source output may also be adjusted according to a color correction matrix, generally expressed as output color = correction matrix x input color, for example:

[R_out]=[M11 M12 M13]×[R_in],

[G_out]=[M21 M22 M23]×[G_in],

[B_out]=[M31 M32 M33]×[B_in],

Wherein each element M11, M12, M13, M21..m 33 in the correction matrix is determined according to a change in light transmittance. Each element of the correction matrix is used to adjust each color channel. And obtaining the output color corresponding to the input color under different light transmittance according to the experiment. The correction matrix parameters for the most appropriate data are found by least squares to minimize the difference between the model predicted color and the target color, and for each data point, the difference between the model predicted color and the target color is calculated and then the squares of these differences are summed to construct a loss function, and the correction matrix parameters are adjusted using a numerical optimization algorithm, such as gradient descent or quasi-newton method, to minimize the loss function. The algorithms will iterate continuously to converge the loss function to a minimum, and thus find the best correction matrix parameters, which will be updated continuously during the iteration until the loss function converges to a value close to zero, indicating that the model has fitted well to the known data points. After the correction matrix parameters are determined, verification and testing is required, the accuracy of the correction model can be verified by using data points not included in the training data, and the effect of the model can be determined by verification to see if it can effectively correct color shift or distortion. Finally, the correction matrix may be applied to the actual color data for color correction. The input color is corrected by matrix multiplication. In the HUD system, if the backlight does not adopt a TFT-LCD liquid crystal display scheme, a multi-channel LED light source can also be adopted, and each channel corresponds to one basic color (red, green and blue) and a brightness adjusting channel. When the transmittance of the electrochromic glass is reduced, the system can reduce the brightness of the corresponding LED channel to compensate for the color distortion, so that the brightness and the contrast of the picture are maintained.

In the above steps, the visibility of the head-up display device can be improved and the perceptibility of the head-up display information by the driver can be improved by ensuring that the contrast ratio of the virtual image and the real environment meets a certain condition and the display color of the virtual image meets a certain condition, thereby improving the driving safety.

For example, before adjusting the transmittance of the sun visor based on the target traveling information, the target environment information, and the target state information, the transmittance of the sun visor may be adjusted to a preset 50% transmittance if it is determined that the illumination intensity of the environment in which the target vehicle is currently located exceeds a preset intensity threshold. When a white vehicle appears in a preset range (for example, within 30 meters) right ahead of the vehicle based on laser radar or/and camera information in sunny days, the illumination intensity of the environment exceeds a preset intensity threshold value, and the transmittance of the target sun visor is rapidly reduced to a preset value (for example, 50% of original transmittance), so that the display effect is not lost when the picture of the target sun visor is overlapped on a front white vehicle scene, and the user experience is ensured.

The HUD system detects the brightness level of the external environment based on a light sensor and/or a camera mounted on the vehicle, and the system can automatically and finely adjust the transmittance (for example, in 1% adjustment) of the sun visor according to the illumination intensity. For example, the minimum illumination intensity is 1000Lux, the maximum illumination intensity is 10000Lux, and the transmittance adjustment range is 30%, then the transmittance will be 13% (intermediate value) when the illumination intensity is 5000Lux, 0% (complete opacity) when the illumination intensity is 1000Lux, and 30% when the illumination intensity is 10000 Lux.
