Detailed Implementation

[0016] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] To improve the convenience and user experience of drawing side views in vehicles, this application provides a display method in one embodiment, such as... Figure 1 As shown, the method includes: Step 101: Determine a first target image of the target seating area of ​​the vehicle. The first target image is an image determined by the acquisition device along a first direction, which is a direction that satisfies the parallel condition with the surface of the vehicle's side window.

[0018] like Figure 2 As shown, the acquisition device is positioned at the front of the vehicle. The device acquires a first target image of the target seating area within the vehicle along a first direction, which is the direction parallel to the surface of the vehicle's side window, i.e., from the front of the vehicle towards the rear. It should be noted that the first direction is not strictly parallel to the surface of the vehicle's side window; it can be approximately parallel, and can be fine-tuned according to the location of the target seating area.

[0019] In this embodiment, the acquisition device can be a standalone camera or a camera integrated into a display device such as a tablet computer installed in the vehicle. The target seating area can be any location in the vehicle where passengers can sit. In other embodiments, the acquisition device can be any device capable of acquiring images.

[0020] Step 102: The first target image is transmitted to the display control unit, which controls the vehicle side window to display the image corresponding to the first target image based on the first target image.

[0021] The acquisition device can transmit the first target image to the display control unit via wired transmission methods such as bus or USB interface, or via wireless transmission methods such as vehicle Ethernet or wireless communication module.

[0022] After receiving the first target image, the display control unit controls the vehicle's side windows to display the image corresponding to the first target image, thus meeting the passenger's need to observe the makeup area. The vehicle side windows can be either the front or rear side windows, primarily determined by the user's target seating area.

[0023] For example, if the target seating area is the left rear seat, and the passenger on the left rear seat needs to apply makeup to the left side of their face, the passenger can face the right side window of the vehicle. At this time, the acquisition device captures an image along a first direction, precisely capturing a first target image including the passenger's left side face, and transmits this first target image to the display control unit via a bus. Upon receiving the first target image, the display control unit controls the right rear side window of the vehicle to display the image corresponding to the first target image. The passenger can directly observe the image of their left side face through the right rear side window, thus allowing for a more natural and comfortable makeup application.

[0024] It should be noted that after receiving the first target image, the display control unit can also control the vehicle's windshield or the vehicle's HUD (head-up display) to display the image corresponding to the first target image.

[0025] For example, if a passenger in the target seating area needs to have their face painted, the passenger can face the front of the vehicle. At this time, the image acquisition device captures an image along a first direction, capturing a first target image including the passenger's front view, and transmits this image to the display control unit via a bus. Upon receiving the first target image, the display control unit controls the vehicle's HUD to display the image corresponding to the first target image. The passenger can directly observe their front view on the vehicle's HUD, allowing for a more natural and comfortable makeup application.

[0026] In the above solution, a first target image of the target seating area is acquired by a data acquisition device along a first direction parallel to the surface of the vehicle's side window. This allows for accurate acquisition of image information of the passenger's left and right sides or other scenes, solving the problem of difficulty in clearly observing the left and right sides when using a small mirror. The data acquisition device transmits the first target image to the display control unit via wired transmission methods such as bus or USB interface, or wireless transmission methods such as in-vehicle Ethernet or wireless communication modules, ensuring the stability and flexibility of image transmission. The display control unit controls the vehicle's side windows, windshield, or HUD to display the corresponding image, allowing passengers to observe their left and right sides or frontal makeup areas in a natural and comfortable posture without having to hold a mirror in one hand and operate cosmetics in the other, or tilt their heads to observe. This effectively improves the convenience of applying or touching up makeup in the vehicle and significantly enhances the user experience.

[0027] This application also provides a display method in one example, such as Figure 3 As shown, the first target image for determining the target vehicle seating area includes: Step 201: Determine if a user exists in the target seating area of ​​the vehicle.

[0028] The presence of a user in the target riding area can be determined by the data collection device or other detection devices in the vehicle.

[0029] In this embodiment, the detection device can be a seat pressure sensor or an infrared sensor. In other embodiments, any other detection device capable of detecting the presence of a user in the target seating area can be used.

[0030] For example, the pressure value is detected in real time by the seat pressure sensor in the target seating area. When the pressure value exceeds the preset pressure value, it is determined that there is a user in the target seating area.

[0031] For example, the acquisition device captures images of the target seating area, and the image recognition module performs human contour recognition on the captured images. If a contour that matches human characteristics is identified, it is determined that a user exists in the target seating area.

[0032] Preferably, the determination can also be made by combining the above methods.

[0033] For example, the pressure value is detected in real time by the seat pressure sensor in the target seating area. When the pressure value exceeds the preset pressure value, the target seating area is captured by the acquisition device. The image recognition module performs human contour recognition on the captured image. If the contour that matches human characteristics is identified, it is determined that there is a user in the target seating area.

[0034] Step 202: Obtain the user's facial image as the first target image.

[0035] Once a user is identified as being in the target seating area, the acquisition device can adjust its acquisition direction using angle adjustment components to focus on the user's facial area and acquire their facial image. Alternatively, it can acquire a full image of the user and then select the user's facial area from that image to obtain their facial image. This facial image is then used as the primary target image.

[0036] In the aforementioned solution, the presence of a user in the target seating area is comprehensively determined by using a data acquisition device, or by using multiple detection devices such as seat pressure sensors and infrared sensors, or by combining data acquisition and detection devices. This improves the accuracy of user detection and reduces misjudgments caused by factors such as the placement of objects. Once a user is identified, the data acquisition device adjusts its orientation to focus on the face or selects a facial area from the overall image to obtain a facial image as the first target image. This allows for more accurate acquisition of the user's facial information, providing a reliable basis for the subsequent display control unit to control the display of the corresponding image on the vehicle's side windows and other devices. This better meets the user's need to observe their own face while applying or touching up makeup in the vehicle, enhancing convenience and user experience.

[0037] This application also provides a display method in one example, such as Figure 4 As shown, the method further includes: Step 301: Obtain the target instruction.

[0038] The system can receive user-issued commands through in-vehicle interactive devices such as in-vehicle voice interaction systems, central control touchscreens, rear armrest buttons, or gesture recognition sensors.

[0039] Step 302: Determine the target user among the multiple users of the vehicle according to the target instruction.

[0040] Upon receiving the target instruction, the system parses it to extract user requirement information, such as the user's location and identity information, thereby identifying the target user among multiple users of the vehicle. Location information can be a description carried in the target instruction or determined by detecting the location where the instruction was issued. Identity information can be pre-stored voiceprint information in the vehicle, or pre-defined mapping data between nicknames and liveness detection; liveness detection can include facial information, etc.

[0041] Step 303: Obtain the facial image of the target user as the first target image.

[0042] For example, there are four users in the vehicle: the driver's seat, the front passenger seat, and two rear seating areas (left and right). The target user's command is "Activate facial display for the user on the right rear seat." After parsing the command, the system extracts "right rear seat" as the target user's location information, identifying the user in that rear right seating area as the target user. The control acquisition device then captures the facial image of the user in the rear right seating area as the first target image.

[0043] For example, there are three users in the vehicle, and the system has pre-stored the mapping relationship between each user's preset nickname and facial information. The target user issues the command "Activate facial display for Xiao Li". After parsing the target command, the system extracts the identity identifier "Xiao Li", compares it with the pre-stored mapping relationship data, and then confirms "Xiao Li" as the target user by detecting the facial information of the three users. The control acquisition device collects the facial image of the user in the rear right-side seating area as the first target image.

[0044] In the aforementioned solution, the target commands issued by the user are acquired through in-vehicle interactive devices such as the in-vehicle voice interaction system, central control touchscreen, rear armrest buttons, or gesture recognition sensors, allowing the user to conveniently initiate requests based on their usage habits. Upon receiving the target command, the system parses it and extracts the target user's location or identity information, thereby identifying the target user from among multiple users in the vehicle. This precise location of the user requiring service avoids mismatches in multi-user scenarios. The system then controls the acquisition device to obtain the target user's facial image as the primary target image, providing an accurate facial display for subsequent steps. This better meets the user's need for a facial image when applying or touching up makeup in the vehicle, further enhancing convenience and user experience.

[0045] This application also provides a display method in one example, such as Figure 5 As shown, the method further includes: Step 401: Acquire the first facial image of the user's face using the acquisition device.

[0046] The first facial image of a user includes images of the user's forehead, eyes, nose, mouth, left and right cheeks, etc. The first facial image fully preserves the original features and details of each part of the user's face, ensuring the integrity of facial information.

[0047] Step 402: Determine the second facial image based on the first facial image.

[0048] When determining the second facial image based on the first facial image, facial feature recognition is first performed on the first facial image. A preset key point detection algorithm can be used to locate the user's target area in the first facial image. Subsequently, the located target area is processed by local magnification and cropping to obtain the second facial image that highlights the user's target area.

[0049] The target area can be obtained from the target command issued by the user, or by sensing the user's motion and facial attention points. End-to-end algorithms are used to identify the part of the user who is applying makeup as the target area, and screen following and automatic scaling are achieved.

[0050] For example, when a user issues the command "I want to draw eyebrows" through the in-vehicle voice interaction system, the system parses the command, extracts the information of "eyebrows", and identifies the user's eyebrow area as the target area.

[0051] For example, when a user is applying eyeliner, motion sensing and facial attention point sensing are used to identify the area the user is applying makeup to as the eyeliner area using an end-to-end algorithm, thus defining the eyeliner area as the target area. The eyeliner area in the second facial image is automatically magnified to achieve detailed visualization. After the user finishes applying eyeliner and starts applying lipstick, the area the user is applying makeup to is identified as the mouth area, and the magnified area in the second facial image is transferred to the user's mouth area to achieve screen tracking.

[0052] For example, when a user is applying eyeliner, the algorithm uses motion sensing and facial attention point sensing, employing an end-to-end algorithm to identify the area the user is applying makeup to as the eyeliner area, thus defining the eyeliner area as the target area. The second facial image is automatically zoomed in on the eyeliner area to achieve detailed visualization. After the user finishes applying eyeliner and begins applying foundation, the algorithm identifies the area the user is applying makeup to as the face, defining the face as the target area. The second facial image is automatically zoomed out to display the user's entire face, achieving overall visualization.

[0053] Step 403: Use the second facial image as the first target image, and display the target area of ​​the user in the content of the second facial image.

[0054] Since the second facial image has been processed to highlight the user's target area, it is used as the first target image and displayed on a display device such as the vehicle's side window, windshield, or HUD, allowing the user to quickly focus on the target area that needs makeup, making it convenient for the user to observe and apply makeup.

[0055] Preferably, a data acquisition device can be used to collect passenger movement and facial information in real time. Based on the movement and facial information, it is determined that the passenger is applying makeup. Then, a first facial image of the user's face is acquired through the data acquisition device, and a second facial image is determined based on the first facial image to highlight the facial areas where the user is applying makeup. The display device is automatically turned on, and the brightness is adjusted to the required level for makeup application by taking into account the passenger's line of sight, ambient light, and the brightness of the second facial image. The adjusted second facial image is then displayed on the display device.

[0056] In the above solution, a first facial image containing the user's forehead, eyes, nose, mouth, and left and right cheeks, retaining their original features and details, is acquired through a data acquisition device, providing a complete facial information foundation for subsequent processing. Then, the user's target area is determined through target commands or recognition algorithms. Facial feature recognition is then performed on the first facial image to identify the target area, which is then locally magnified and cropped to obtain a second facial image highlighting the target area, making the areas requiring makeup clearer and more prominent. Through motion perception and facial attention point perception, an end-to-end algorithm enables the screen to follow the user's makeup application position and automatically scale the displayed image based on the user's makeup application position, further improving the user experience during makeup application. The second facial image is presented as the first target image on display devices such as vehicle side windows, windshields, or HUDs, allowing users to quickly focus on the target area requiring makeup, facilitating observation and operation, thus better meeting the user's needs for makeup application or touch-ups in the vehicle and improving convenience and user experience.

[0057] This application also provides a display method in one example, the method further comprising: The display control unit controls the vehicle side windows on both sides of the target seating area to display the image corresponding to the first target image based on the first target image.

[0058] After receiving the first target image, the display control unit controls the vehicle side windows located on both sides of the target seating area to display the image corresponding to the first target image, so that users in the target seating area can flexibly choose to observe either side window according to their own needs, thus improving the convenience of use.

[0059] For example, if the target seating area is the middle rear seat, the display control unit continuously receives the first target image of the user in the middle rear seat from the acquisition device, and controls the left and right rear side windows to simultaneously display the images corresponding to the first target image. When the user in the middle rear seat is facing the left rear side window, the first target image acquired by the acquisition device is an image of the user's right side face, at which point the user can observe their right side face and apply makeup to it. When the user turns to the right rear side window, the first target image acquired by the acquisition device is an image of the user's left side face, at which point the user can observe their left side face and apply makeup to it.

[0060] In the above solution, the display control unit controls the side windows on both sides of the target seating area of ​​the vehicle to display the image corresponding to the first target image, so that the user in the target seating area no longer needs to interact with the vehicle and can flexibly choose to observe either side of the side window according to their needs. Whether they need to observe the left or right side of their face to apply makeup, they can easily find a suitable viewing angle, making it more convenient for users to apply or touch up their makeup in the vehicle, and improving the comfort and overall experience of use.

[0061] This application also provides a display method in one example, the method further comprising: The vehicle side window displays an image corresponding to the first target image based on the distance between the user in the target seating area and the vehicle side window. The vehicle side window closer to the user has a first display image corresponding to the target object, and the vehicle side window farther from the user has a second display image corresponding to the target object. The size of the target object in the second display image is larger than the size of the target object in the first display image.

[0062] The distance data between the user and the side windows of the vehicle on both sides of the target seating area can be collected in real time using distance sensors or depth detection functions built into the acquisition device. After receiving the distance data, the display control unit adjusts the collected facial image of the user based on the distance data between the user and the side windows of the vehicle on both sides of the area, so that the user can see a facial image of an appropriate size whether viewing a vehicle side window that is closer or a vehicle side window that is farther away due to light difference.

[0063] For example, the target seating area is the middle rear seat. After acquiring distance data, the display control unit determines that the user in the middle rear seat is 0.4 meters away from the left rear side window and 0.9 meters away from the right rear side window. The size of the first target image is adjusted to 1440×1080 pixels to serve as the display image for the left rear side window, which is closer to the user. The size of the second target image is adjusted to 1920×1440 pixels to serve as the display image for the left rear side window, which is farther away from the user.

[0064] In the above solution, the distance sensors or depth detection function built into the acquisition devices around the target seating area of ​​the vehicle can acquire real-time distance data between the user and the side windows of the vehicle. After receiving the distance data, the display control unit adjusts the size of the first target image according to the distance data, so that the side window closer to the user displays a first display image of a suitable size, and the side window farther away from the user displays a second display image of a larger size. This allows the user to see a properly sized facial image regardless of whether they are looking at a nearby or distant side window. For example, when a passenger tilts their head to look at their face, their gaze falls on the window, and a properly sized image is displayed on the window. The passenger will see the makeup area in the image on the window more naturally and comfortably, making it more convenient to apply or touch up makeup in the vehicle, thus improving the convenience and comfort of use.

[0065] This application also provides a display method in one example, such as Figure 6 As shown, the method further includes: Step 501: Determine a second target image of the vehicle's target seating area. The second target image is an image determined by the acquisition unit of the vehicle's side window along a second direction, and the second direction has an angle with the first direction.

[0066] like Figure 7 As shown, the acquisition unit is positioned at the side window of the vehicle. The acquisition unit acquires a second target image of the target seating area within the vehicle along a second direction. This second direction has a certain angle with the first direction to obtain a different perspective than the first direction. It should be noted that the angle between the second and first directions is not strictly a single angle and can be fine-tuned according to the location of the target seating area.

[0067] Step 502: The second target image is transmitted to a display device, and the display device displays an image corresponding to the second target image based on the second target image.

[0068] The acquisition unit can transmit the second target image to the display device via wired transmission methods such as bus or USB interface, or via wireless transmission methods such as vehicle Ethernet or wireless communication module.

[0069] After receiving the second target image, the display device displays the image corresponding to the second target image to meet the passenger's need to observe the makeup area. The display device can be a tablet computer or similar device installed in the vehicle.

[0070] For example, if the target seating area is the middle rear seat, the display device continuously receives a second target image of the user in the middle rear seat from the acquisition unit and displays the image corresponding to the second target image. When the user in the middle rear seat is facing the display device, the second target image acquired by the acquisition unit on the right side of the vehicle is an image of the user's right side of their face. At this time, the user can observe their right side of their face and apply makeup to it. The second target image acquired by the acquisition unit on the left side of the vehicle is an image of the user's left side of their face. At this time, the user can observe their left side of their face and apply makeup to it.

[0071] It should be noted that users can control the display device to show the image of the second target captured by either acquisition unit via the interactive device. Users can also control the display device to simultaneously show the images of the second target captured by both acquisition units via the interactive device.

[0072] In the above solution, by setting up a collection unit on the vehicle side window to collect a second target image of the target seating area along a second direction at an angle to the first direction, an image from a different perspective than the first direction can be obtained, providing users with a more comprehensive facial observation angle. After receiving the second target image, the display device displays the corresponding image. Furthermore, the user can control the display device to display the images corresponding to the second target images collected by the collection units on either side or simultaneously via an interactive device. This allows users to flexibly choose their observation angle according to their needs, better meeting the needs of passengers observing makeup areas in the vehicle, and further improving the convenience and flexibility of use.

[0073] This application also provides a display method in one example, such as Figure 8 As shown, the method further includes: Step 601: Determine the first target image and the second target image of the vehicle target riding area.

[0074] The acquisition device acquires a first target image of the target riding area in the vehicle along a first direction, and the acquisition unit acquires a second target image of the target riding area in the vehicle along a second direction.

[0075] Step 602: The vehicle side window displays the image corresponding to the first target image and the image corresponding to the second target image based on the first target image and the second target image.

[0076] The display control unit can control one side of the vehicle's side window to simultaneously display the image corresponding to the first target image and the image corresponding to the second target image, or control both sides of the vehicle's side windows to respectively display the image corresponding to the first target image and the image corresponding to the second target image.

[0077] Step 603: The display device displays the image corresponding to the first target image and the image corresponding to the second target image based on the first target image and the second target image.

[0078] After receiving the first target image and the second target image, the display device can simultaneously display the image corresponding to the first target image and the image corresponding to the second target image.

[0079] In the above solution, a first target image of the target seating area is acquired along a first direction by the acquisition device, and a second target image of the target seating area is acquired along a second direction by the acquisition unit, providing the user with facial images from different perspectives. The display control unit can control a single vehicle side window to simultaneously display the image corresponding to the first target image and the image corresponding to the second target image, or to allow the two vehicle side windows to display different images respectively, depending on the actual scene. The display device can also simultaneously display the image corresponding to the first target image and the image corresponding to the second target image, allowing the user to observe facial images from multiple angles at the same time through flexible display methods. Whether through the vehicle side window or the display device, the user can conveniently obtain facial image information from multiple perspectives, thereby more comprehensively viewing the details of the makeup area, better meeting the needs of different observation angles when applying or touching up makeup in the vehicle, and improving the convenience and flexibility of use.

[0080] This application also provides a display method in one example, such as Figure 9 As shown, the method further includes: Step 701: Determine the height information of the users in the target seating area of ​​the vehicle.

[0081] The system can acquire user images in real time using a data acquisition device and then perform image recognition to obtain the user's height information. Alternatively, it can record the vertical height parameters of the user's seat in real time using a seat height adjustment sensor, or emit infrared signals towards the user and receive the reflected signals using an infrared ranging sensor, calculating the vertical distance between the user's head and the roof based on the signal transmission time, thus providing the user's height information.

[0082] Step 702: Adjust the position of the image corresponding to the first target image displayed on the vehicle side window according to the height information.

[0083] After the display control unit obtains the user's height information, it calculates the display offset to match the user's eye level based on the display area coordinates of the vehicle side window and the user's height information, thereby adjusting the position of the image corresponding to the first target image displayed on the vehicle side window.

[0084] For example, if the target seating area is the front passenger seat, an infrared sensor on the roof detects a distance of 0.4 meters between the user's head and the roof. Given a roof height of 1.8 meters, the user's eye level is calculated to be 1.4 meters, which is the user's height information. The vertical coordinate range of the display area on the right side window of the front seat is from 0.5m to 1.5m. The center of the first target image's face is displayed at a height of 1m. Because the user's eye level of 1.4 meters is higher than the display center, the display control unit calculates an upward offset of 0.2m and adjusts the display center to 1.2m, making the image position compatible with the user's eye level, allowing the user to naturally observe the facial image without looking down.

[0085] In the above solution, the height information of the user in the target seating area can be accurately obtained through various methods, such as image recognition by a data acquisition device, parameter recording by a seat height adjustment sensor, or distance calculation by an infrared ranging sensor. After obtaining the user's height information, the display control unit calculates the display offset that matches the user's line of sight height by combining it with the display area coordinates of the vehicle's side window, and then adjusts the image position corresponding to the first target image on the side window. This allows the user's line of sight to naturally match the image position, enabling easy observation of the facial image without having to deliberately look up, down, or adjust body posture. This better meets the observation needs when applying or touching up makeup in the vehicle, further enhancing the convenience and comfort of use.

[0086] This application also provides a display method in one example, the method further comprising: The vehicle side window has a first display area and a second display area. After receiving a first target image, the display control device controls the first display area of ​​the vehicle side window to display the image corresponding to the first target image. It also controls the second display area of ​​the vehicle side window to display the image corresponding to a third target image, which is the first target image for generating a recommended makeup look based on first display parameters.

[0087] The display area of ​​the vehicle's side window is pre-divided into a first display area and a second display area, which are independent of each other. Upon receiving a first target image, the display control device directly controls the first display area of ​​the vehicle's side window to display the image corresponding to the first target image, allowing the user to observe their actual facial appearance. Simultaneously, the display control device invokes a preset makeup recommendation algorithm to process the first target image according to first display parameters, generating a third target image with recommended makeup. The second display area of ​​the vehicle's side window then displays the image corresponding to the third target image, achieving synchronous display of the original image and the recommended makeup image. The first display parameters may include the user's facial features, current lighting conditions, and preset makeup styles. The makeup recommendation algorithm can be implemented using content-based image recommendation algorithms, collaborative filtering algorithms, etc.

[0088] In the above solution, the display area of ​​the vehicle's side window is pre-divided into an independent first display area and a second display area. When the display control device receives the first target image, it directly presents the user's original facial image in the first display area, allowing the user to easily observe their actual facial condition. Simultaneously, the display control device calls a preset makeup recommendation algorithm, combining the user's facial features, current lighting conditions, preset makeup styles, and other first display parameters to process the first target image, generating a third target image with recommended makeup, which is then simultaneously displayed in the second display area. By presenting the original facial image and the recommended makeup image in a partitioned comparison, users can intuitively see different makeup effects and can refer to the recommended makeup for makeup application or adjustments without additional operation. This better meets the user's needs for previewing and operating makeup effects in the vehicle, improving convenience and practicality.

[0089] This application also provides a display method in one example, the method further comprising: Obtain environmental information, and determine a second display parameter based on the environmental information and the first target image.

[0090] The vehicle side window adjusts the first target image based on the second display parameters and displays the image corresponding to the adjusted first target image.

[0091] Environmental information, including but not limited to in-vehicle light intensity, ambient color temperature, and vehicle vibration, can be acquired through multiple environmental sensors in the vehicle, such as light sensors, color temperature sensors, and vibration sensors. This information is then combined with the display status of the user's face in the first target image, such as facial glare, image motion blur, and color fidelity. A comprehensive analysis of the impact of environmental information on image display is performed, including issues such as loss of detail due to insufficient lighting, distorted skin tones due to color temperature deviation, and image blurring due to vibration. Based on preset adaptation rules, second display parameters, encompassing brightness adjustment, color temperature correction, sharpening parameters, and anti-blur coefficients, are determined.

[0092] After receiving the second display parameters, the vehicle's side window performs comprehensive optimization processing on the first target image based on these parameters. This includes adjusting local brightness to address lighting issues, correcting image color tones to address color temperature deviations, and enhancing image sharpness to mitigate vibration effects, avoiding display imbalances caused by isolated adjustments. The processed image is then transmitted to the vehicle's side window, which is controlled to present the image in a way that adapts to the current environment, ensuring that the user's facial details remain clear and natural even in complex conditions.

[0093] Image processing algorithms can be used to combine the user's facial features in the first target image with the collected in-vehicle lighting intensity to simulate a first target image with suitable lighting for makeup, and then display it on the screen.

[0094] For example, if a passenger needs to apply makeup in a dimly lit environment, the image processing algorithm can automatically adjust the brightness of the displayed image on the screen to facilitate the user's makeup application without the passenger needing to turn on a light.

[0095] This application also provides a display method in one example, the method further comprising: The second display parameters are determined based on the ambient lighting information and the first target image, wherein the ambient lighting information includes the ambient lighting information.

[0096] The vehicle side window adjusts the first target image based on the second display parameters and displays the image corresponding to the adjusted first target image.

[0097] The ambient light intensity data inside the vehicle can be collected in real time by the vehicle's light sensor, or the ambient brightness can be evaluated by using the exposure parameters built into the collection device to obtain ambient light information.

[0098] A local brightness analysis is performed on the user's facial region in the first target image to calculate the average pixel brightness value of that region. Environmental information is then combined with the facial region brightness value, and a second display parameter is determined by comparing it against a preset brightness threshold rule. The second display parameter includes a brightness enhancement coefficient and a contrast adjustment range.

[0099] The vehicle's side window performs targeted processing on the first target image based on the received second display parameters. For example, it uses image enhancement algorithms to boost the brightness and optimize the contrast of facial areas that require additional lighting, as indicated by the second display parameters, to avoid overall overexposure and make the details of makeup areas clearer and easier to discern.

[0100] In the above solution, ambient light information is acquired in real time through the built-in parameters of the vehicle's light sensor or acquisition device. Local brightness analysis is then performed on the user's facial area in the first target image. The ambient light information and facial area brightness are combined with a preset threshold to determine second display parameters, including brightness enhancement coefficients and contrast adjustment ranges. Based on these second display parameters, the vehicle's side window uses an image enhancement algorithm to specifically process the first target image, increasing brightness and optimizing contrast in facial areas requiring supplemental lighting to avoid overall overexposure and make makeup details clearer. By automatically adjusting the image display effect according to ambient light information and facial area brightness, users can clearly observe facial details in different environments, meeting their observation needs during makeup application without manual adjustment, further enhancing ease of use.

[0101] This application also provides a display method in one example, the method further comprising: The second display parameters are determined based on the vehicle vibration information and the first target image, wherein the environmental information includes the vehicle vibration information.

[0102] The vehicle side window adjusts the first target image based on the second display parameters and displays the image corresponding to the adjusted first target image.

[0103] Vibration sensors can be used to collect data such as the amplitude and frequency of vibrations during vehicle operation, or the motion detection module built into the acquisition device can be used to assess the degree of image shake in order to obtain vehicle vibration information.

[0104] The first target image is dynamically analyzed to detect jitter features such as facial region displacement and edge blurring, and the jitter offset and blur coefficient are calculated. The vehicle jitter information is combined with the image jitter features and compared with preset anti-shake threshold rules to determine the second display parameters. The second display parameters include anti-shake correction coefficients, image movement offset, and sharpening enhancement parameters.

[0105] The vehicle's side window performs targeted processing on the first target image based on the received second display parameters. For example, it eliminates image blurring caused by shaking through anti-shake algorithms such as motion compensation and image registration, and adjusts the display position of the facial area in the image in real time based on the following movement offset to keep it synchronized with the user's actual facial position, avoiding image shaking or offset caused by vehicle bumps.

[0106] In the above solution, vehicle vibration information is acquired in real time through the vehicle's vibration sensor or the built-in module of the acquisition device. The shaking characteristics of the facial region in the first target image are analyzed, and the vehicle vibration data and image shaking characteristics are combined with a preset threshold to determine a second display parameter, including an anti-shake correction coefficient and an image movement offset. Based on the second display parameter, the vehicle's side window uses an anti-shake algorithm and image position adjustment to eliminate blur caused by shaking and make the image follow facial movement. This ensures that users can still stably and clearly observe facial details even when the vehicle is moving and bumpy, without needing to frequently adjust their gaze due to image shake, further improving ease of use and viewing experience.
