Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and more particularly to a rearview mirror, a motor vehicle, and a method for adjusting the rearview mirror. Background Technology

[0002] Rearview mirrors typically use a fixed camera to adjust the field of view, adjusting the view by moving the image cropping area, rather than using mechanical transmission to control the camera angle.

Detailed Implementation

[0017] In this disclosure, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c alone can mean: a alone, b alone, c alone, a combination of a and b, a combination of a and c, a combination of b and c, or a, b, and c, where a, b, and c can be single or multiple. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] The terms “center,” “longitudinal,” “lateral,” “up,” “down,” “left,” “right,” “front,” “back,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and are not intended to 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 limiting this disclosure.

[0019] The terms "connected" and "connected" should be interpreted broadly. For example, in circuit structures, "connected" or "connected" can refer not only to physical connections but also to electrical or signal connections. This could be a direct connection (physical connection) or an indirect connection via at least one intermediate component, as long as the circuit is connected. It could also refer to the internal connection between two components. Similarly, a signal connection can refer to a connection via a circuit or a medium, such as radio waves. Those skilled in the art will understand the specific meaning of these terms in this disclosure based on the specific circumstances.

[0020] The term "motor vehicle" as used in this disclosure refers to a wheeled motor vehicle that is driven or towed by a power unit, travels on roads, and is used for carrying passengers, transporting goods, or performing specialized engineering operations. Motor vehicles can include automobiles, new energy vehicles, and motorcycles, among others.

[0021] The rearview mirror disclosed herein can be applied to motor vehicles. Users can view the situation behind and to the sides of the vehicle through the rearview mirror. The rearview mirror in this disclosure can be a streaming media rearview mirror, which is a type of peripheral electronic product, typically connected to a camera to transmit the image from behind the vehicle to the rearview mirror. The camera can be fixed, for example, it can be fixed to the rearview mirror, or it can be separate from the rearview mirror and fixed next to the high-mounted brake light at the rear of the vehicle, etc. The camera's field of view is larger than the required field of view of the rearview mirror; the field of view in this disclosure can also be referred to as the field of view range or field of view angle.

[0022] Figure 1a This is one of the schematic diagrams illustrating the principle of field of view acquisition in a rearview mirror according to an embodiment of this disclosure. Figure 1b For the second schematic diagram illustrating the principle of field of view acquisition in a rearview mirror according to an embodiment of this disclosure, please refer to [link / reference]. Figure 1a and Figure 1b The field of view of a rearview mirror refers to the spatial range corresponding to the image displayed in the rearview mirror. The rearview mirror displays a portion of the camera's view, cropped through the viewfinder, thus simulating the rearview mirror's field of view. Figure 1 on the left exemplarily illustrates the camera's field of view, that is, image frame 101 is the image captured by the camera. The image in viewfinder 102 is the rearview mirror's field of view. Viewfinder 102 can be moved within image frame 101 to crop the image frame 101 and obtain the rearview mirror's field of view.

[0023] Specifically, when adjusting the rearview mirror's field of view, it is usually not necessary to adjust the camera itself. Instead, the position of the viewfinder within the camera's view is adjusted to achieve the same effect. As illustrated on the left side of Figure 1, the viewfinder 102 can move in any direction within the image frame 101, such as up, down, left, right, upper left, lower left, upper right, or lower right, thereby cropping the image to different positions. This process is equivalent to adjusting the rearview mirror's field of view.

[0024] The rearview mirror includes a support, a connecting part, and a body. The support is movably connected to the body through the connecting part. The rearview mirror also includes a display module and a controller. The display module is mounted on the body.

[0025] If a rearview mirror has buttons for adjusting the field of vision, it typically includes at least up, down, left, and right buttons. However, while driving, too many buttons can easily distract the driver, making it difficult for them to operate the rearview mirror to adjust the field of vision, resulting in low adjustment efficiency and a poor user experience.

[0026] If the rearview mirror is adjusted via a touchscreen display, it typically displays buttons for up, down, left, and right. However, while driving, too many buttons can easily distract the driver, making it difficult to adjust the mirror's visibility and resulting in low efficiency. Furthermore, in motorcycle driving scenarios, rain or accidental touches by the driver could reduce product reliability. The user experience is poor.

[0027] Furthermore, the rearview mirror may also include adjustment buttons or adjustment sensors; the controller is connected to the display module, adjustment buttons, and adjustment sensors respectively.

[0028] When adjusting the field of view of the rearview mirror, it can usually be done by pressing buttons or using a touch screen.

[0029] The rearview mirror adjustment method disclosed herein, as exemplarily shown on the right side of Figure 1, involves the rearview mirror responding to a user's first operation by adjusting the display screen according to the direction indicated by the first operation. The first operation includes adjusting the angle of the rearview mirror. The displayed screen is a portion of a camera image, acquired through the rearview mirror and / or a camera on the vehicle. The user can manually adjust the rearview mirror, and the rearview mirror adjusts the display screen accordingly based on the user's angle adjustment, thereby adjusting the field of vision. This reduces the number of buttons on the rearview mirror, improves product stability, and allows for intuitive user operation by manually adjusting the rearview mirror, reducing distraction during driving and enhancing the user experience.

[0030] The technical solutions and beneficial effects of this disclosure will be described in detail below with specific embodiments.

[0031] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a rearview mirror adjustment method provided in an embodiment of this disclosure. Figure 2 As shown, the method provided in this embodiment includes the following steps.

[0032] Step 201: In response to the user's first operation, adjust the display screen of the rearview mirror according to the direction indicated by the first operation.

[0033] The first operation includes adjusting the angle of the rearview mirror; that is, the first operation is a manual adjustment of the position of the rearview mirror. The direction indicated by the first operation is the direction in which the angle of the rearview mirror changes through the first operation.

[0034] The displayed image is the view from the rearview mirror, and the displayed image is a portion of the video feed. The video feed is obtained through the rearview mirror and / or the vehicle's camera.

[0035] For example, the first operation is to tilt the rearview mirror downwards, which will cause the display screen of the corresponding rearview mirror to move downwards in the camera view.

[0036] Furthermore, rearview mirrors typically incorporate an attitude detection module. This module measures the mirror's own attitude to obtain attitude data. The rearview mirror uses this module to detect changes in its own attitude. The attitude detection module can be located within the ball joint of the rearview mirror, and it can detect the user's first adjustment of the ball joint.

[0037] Furthermore, the attitude detection module can be a gyroscope.

[0038] Attitude data is used to describe the attitude of an object; the attitude data in this disclosure describes the attitude of a rearview mirror. Attitude data can take many forms. For example, attitude data can be quaternions or Euler angles. Quaternions are commonly used to represent rotational attitude. Euler angles can include pitch angle, roll angle, and yaw angle.

[0039] The attitude detection module detects the attitude of the rearview mirror and obtains attitude data, for example, by sampling. This detection can be performed in real-time or asynchronously, such as with a delay of 0.1-2 seconds.

[0040] In this embodiment, the rearview mirror responds to a user's first operation and adjusts its display according to the direction indicated by the first operation. The first operation includes adjusting the angle of the rearview mirror. The displayed image is a portion of a camera view, which is acquired through the rearview mirror and / or a camera on the vehicle. The user can manually adjust the rearview mirror, and the mirror adjusts its display accordingly based on the user's angle adjustment, thus adjusting the field of vision. This reduces the number of buttons in the rearview mirror, improves product stability, and allows for intuitive user operation by manually adjusting the mirror, reducing distraction during driving and enhancing the user experience. Utilizing the existing posture detection module in the rearview mirror requires minimal modification, thus reducing costs.

[0041] In some embodiments, step 200 is included before step 201.

[0042] Step 200: In response to the user's second operation, enter the field of view adjustment mode.

[0043] The second operation includes triggering the adjustment button of the rearview mirror or the adjustment sensor of the rearview mirror.

[0044] Adjustment buttons or sensors can be installed on the rearview mirror. The second operation is performed on the adjustment button or sensor. The adjustment button can be a physical button, and the second operation corresponding to the adjustment button can be a press operation received at the adjustment button. The adjustment sensor can be a touch sensor, infrared sensor, pressure sensor, etc., and the second operation corresponding to the adjustment sensor can be generated when the signal triggered by the sensor reaches a preset range.

[0045] The field of view adjustment mode refers to the mode in which the display screen of the rearview mirror is adjusted accordingly by changing the angle of the rearview mirror.

[0046] In practical applications, adjustment buttons or adjustment sensors are set on the rearview mirror. After the rearview mirror is activated, if the user wants to adjust the field of view of the rearview mirror, they can press the adjustment button or adjustment sensor. The rearview mirror receives the second operation of the user through the adjustment button or adjustment sensor and puts itself into the field of view adjustment mode.

[0047] In this embodiment, adjustment buttons or sensors are installed on the rearview mirror. Upon receiving a second operation corresponding to the adjustment button or sensor, the rearview mirror enters a field-of-view adjustment mode. In this mode, the user manually adjusts the rearview mirror, and the mirror adjusts the displayed image accordingly based on the direction indicated by the user's first operation, thereby adjusting the rearview mirror's field of view. This reduces the number of buttons on the rearview mirror, improves product stability, and allows for intuitive user operation by triggering the adjustment buttons or sensors and manually adjusting the rearview mirror. This reduces distraction during driving and improves the user experience. Utilizing the existing posture detection module in the rearview mirror requires minimal modification to the mirror itself, thus reducing costs.

[0048] Furthermore, step 201 may include step 2011.

[0049] Step 2011: In response to the user's first operation, adjust the position of the viewfinder in the camera frame according to the direction indicated by the first operation and in a first manner, and display the display screen determined by the viewfinder.

[0050] The viewfinder is used to crop the camera image.

[0051] The field-of-view adjustment mode refers to adjusting the position of the viewfinder frame within the camera's view by changing the angle of the rearview mirror, thereby adjusting the rearview mirror's field of view. The viewfinder frame refers to the area of ​​the camera's view that is cropped. In this mode, the rearview mirror's field of view can be adjusted according to the user's input. It can be understood that the camera's field of view is larger than the rearview mirror's field of view; the rearview mirror's field of view is a portion of the camera's field of view, and thus displays that portion of the image. If, during manual adjustment of the rearview mirror, the viewfinder frame has already moved to the edge of the camera's view, further manual adjustment of the rearview mirror will not move the viewfinder. Additionally, the system will simultaneously prompt the user that the rearview mirror's field of view cannot be adjusted further, and that manual adjustment of the camera is now possible.

[0052] The first method refers to adjusting the position of the viewfinder so that the field of view of the rearview mirror changes with the attitude of the rearview mirror.

[0053] The viewfinder is used to crop the camera footage to obtain the displayed image. The viewfinder is a cropped section of the camera footage, containing the image within it. The camera footage is obtained through the rearview mirror and / or the vehicle's camera.

[0054] In practical applications, adjustment buttons or sensors are installed on the rearview mirror. After the rearview mirror is activated, if the user wants to adjust the field of view, they can press the adjustment button or sensor. The rearview mirror receives this second operation from the user and enters the field of view adjustment mode. In this mode, the attitude detection module in the rearview mirror acquires the attitude data of the mirror's ball joint. The user can then manually adjust the ball joint. The mirror's controller responds to this first operation, adjusting the viewfinder's position in the camera's view according to the first method. The user can continuously adjust the ball joint based on the displayed image until the field of view is adjusted to the desired angle, thus achieving the purpose of adjusting the rearview mirror's field of view.

[0055] The method of this embodiment is illustrated below with an example. Please refer to [link / reference]. Figure 3A and Figure 3B , Figure 3A This is a schematic diagram of the viewfinder position before the field of view is raised, provided in an embodiment of the present disclosure. Figure 3B This is a schematic diagram illustrating the viewfinder position after the field of view has been raised, as provided in an embodiment of this disclosure. The current field of view of the rearview mirror is as follows: Figure 3A As shown, Figure 3AThe image shown is a camera view, currently containing vehicle 31. The clearly visible area 301 in the center of the image is the viewfinder area. The masked area 302, excluding the clearly visible area 301, represents the portion of the image not captured by the viewfinder. When the user presses and holds the adjustment button and rotates the rearview mirror upwards along the ball joint to raise the field of view, the controller in the rearview mirror uses a gyroscope to detect the angle of the mirror's elevation and accordingly moves the viewfinder to the appropriate position. Figure 3B As shown, this allows the user to raise the rearview mirror's field of vision.

[0056] In this embodiment, adjustment buttons or sensors are provided on the rearview mirror. Upon receiving a second operation corresponding to the adjustment button or sensor, the rearview mirror enters a field-of-view adjustment mode. In this mode, the user manually adjusts the rearview mirror. Based on the user's first operation, the rearview mirror adjusts the position of the viewfinder in the camera's view and displays the adjusted image. The user can continuously adjust the rearview mirror manually according to the displayed image until the desired angle of view is achieved, thus achieving the purpose of adjusting the rearview mirror's field of view. This reduces the number of buttons on the rearview mirror, improves product stability, and allows for field-of-view adjustment by the user triggering the adjustment button or sensor, aligning with user intuition and reducing distraction during driving, thereby improving the user experience.

[0057] In some embodiments, the method of this embodiment may further include step 203.

[0058] Step 203: In modes other than the field of view adjustment mode, adjust the posture of the rearview mirror and adjust the display screen of the rearview mirror according to the second method so that the field of view of the rearview mirror remains unchanged.

[0059] The second method refers to adjusting the viewfinder to maintain a constant field of view in the rearview mirror. The first and second methods differ.

[0060] In modes other than the field of view adjustment mode, when a change in the posture of the rearview mirror is detected, the display screen of the rearview mirror is adjusted according to the second method to keep the field of view of the rearview mirror unchanged. The first method and the second method are different.

[0061] Furthermore, adjusting the rearview mirror display in the second manner can be achieved by adjusting the position of the viewfinder in the camera frame in the second manner so that the field of view of the rearview mirror remains unchanged.

[0062] In this embodiment, if the viewfinder is not in the field-of-view adjustment mode, for example, after activating the rearview mirror or after exiting the field-of-view adjustment mode, the image stabilization mode can be entered. Image stabilization mode maintains a constant field of view under bumpy conditions. The viewfinder movement strategy in image stabilization mode aims to keep the field of view as unchanged as possible, similar to gimbal adjustment; even if the handheld angle changes, the orientation remains the same. This is achieved through a wide field of view and cropping of the camera. When a change in the rearview mirror's posture data is detected, the position of the viewfinder in the camera's viewfinder is adjusted according to this change to ensure the rearview mirror's field of view remains constant.

[0063] For example, if a user feels that the rearview mirror screen angle is not good after adjusting the field of view, such as being too tilted or having glare, the user can directly adjust the angle of the rearview mirror without pressing the adjustment button or triggering the adjustment sensor. At this time, as the angle of the rearview mirror screen changes, the field of view of the rearview mirror should remain as constant as possible.

[0064] In some embodiments, the method of this embodiment may further include step 204 after step 200.

[0065] Step 204: After entering the field of view adjustment mode, display the field of view adjustment instruction information; and / or, turn on the field of view adjustment indicator light.

[0066] The field of view adjustment indicator is displayed to indicate that the view adjustment mode is currently active. This indicator can be text-based, such as "Currently in field of view adjustment mode" or "Please adjust your view." Alternatively, it can be an icon-based indicator, such as a highlighted icon for the field of view adjustment mode.

[0067] The field-of-view adjustment indicator light is used to indicate whether the field-of-view adjustment mode is currently in effect. The indicator light can be red, yellow, etc., and this disclosure does not limit the color of the indicator light. After the field-of-view adjustment indicator light is turned on, it can remain constantly lit or flash; this disclosure does not limit the flashing of the indicator light either.

[0068] In practical applications, after the rearview mirror enters the field of view adjustment mode, field of view adjustment instruction information can be displayed on it, and / or the field of view adjustment indicator light can be turned on.

[0069] If the current field of view adjustment mode is indicated by displaying a field of view adjustment indicator, then the field of view adjustment indicator can be displayed in all field of view adjustment modes; alternatively, the field of view adjustment indicator can be displayed when entering field of view adjustment mode.

[0070] If the field of view adjustment indicator light indicates that you are currently in field of view adjustment mode, you can keep the indicator light on or flash continuously in field of view adjustment mode; or you can turn on the field of view adjustment indicator light when entering field of view adjustment mode.

[0071] In this embodiment, by displaying field of view adjustment instruction information and / or turning on the field of view adjustment indicator light in the field of view adjustment mode, the user is prompted that they are currently in the field of view adjustment mode, thereby improving the user experience.

[0072] In some embodiments, step 2011 may include step 20111.

[0073] Step 20111: According to the direction of the first operation instruction and the adjustment ratio, adjust the position of the viewfinder on the camera screen in the first way, and display the screen determined by the viewfinder.

[0074] The adjustment ratio refers to the ratio of the change in the rearview mirror's posture data to the movement of the viewfinder on the screen.

[0075] Furthermore, the adjustment ratio value is a preset value; or, the adjustment ratio value is a value determined based on the adjustment speed of the rearview mirror and / or changes in the camera's field of view. The adjustment speed value can be either the adjustment speed or the adjustment acceleration. The following is an example of how to obtain the adjustment ratio value.

[0076] In one possible implementation, the adjustment ratio value can be a preset value, for example, an adjustment ratio value that corresponds to the angle information can be preset.

[0077] In another possible implementation, since users may adjust the rearview mirror too quickly or accelerate excessively when manually adjusting it, but do not actually want to adjust the field of vision too much, the adjustment ratio can be determined based on the speed or acceleration of adjusting the rearview mirror during the field of vision adjustment process. For example, when the adjustment speed reaches a preset value, the adjustment ratio can be reduced by a certain percentage from the preset value.

[0078] In another possible implementation, the camera can be mounted on the rearview mirror, for example, on a motorcycle. In the field-of-view adjustment mode, when the user manually adjusts the rearview mirror, the camera moves with the mirror's rotation, changing its field of view. In this scenario, the rearview mirror may have rotated a small angle, but the displayed image will show a much larger movement. Please see [link to relevant documentation]. Figures 4A-4C , Figure 4A This is a schematic diagram of a scene before camera adjustment provided in an embodiment of this disclosure. Figure 4B This is a schematic diagram of a scene after camera adjustment, provided in an embodiment of this disclosure. Figure 4CThis is a schematic diagram of a scene after image stabilization processing, provided in an embodiment of this disclosure. For example... Figure 4A As shown, the image area refers to the field of view of the camera device, the framing area refers to the field of view of the rearview mirror, and the scene includes the sun A and a tree, where the tree includes the treetop point B, the middle point C, and the base point D. Figure 4A The camera's field of view, as shown, captures an image of the tree but not of the sun (A). When the camera is rotated slightly upwards, as... Figure 4B As shown, with the viewfinder position unchanged, the tree is not visible in the display, or only the treetop point B is visible, while most of the image shows the sky, in which case the sun A is visible. Therefore, the viewfinder needs to be adjusted accordingly, such as... Figure 4C As shown, while the camera rotates, the viewfinder is moved to slightly raise the image, so that the treetop point B and the middle point C are visible in the display screen, but the bottom point D is not visible.

[0079] Building upon the three possible implementations described above, a further step is to set a maximum manual adjustment angle for the rearview mirror. Beyond this maximum angle, manual adjustment of the rearview mirror becomes impossible. When the maximum manual adjustment angle is set, the viewfinder moves to the edge of the corresponding camera frame. For example, if the rearview mirror is manually adjusted to its maximum position to the right, the viewfinder will be at the far right of the camera frame.

[0080] The rearview mirror does not have a maximum manual adjustment angle, and can be manually adjusted at any angle. In this case, the position of the viewfinder in the camera frame can be moved accordingly during the manual adjustment of the rearview mirror. Using relative position, as long as the rearview mirror rotates relative to the viewfinder, the field of view of the rearview mirror will shift relative to the viewfinder. This provides a greater degree of freedom.

[0081] In this embodiment, the attitude detection module detects the attitude of the rearview mirror, comparing the current attitude data with the attitude data obtained at the previous sampling time or a previous moment to determine the direction and angle information for adjusting the rearview mirror. By using the direction and angle information of the rearview mirror, along with the adjustment ratio, the movement of the viewfinder within the camera frame can be determined, thereby adjusting the position of the viewfinder within the camera frame. This allows for quick and accurate adjustment of the viewfinder position, resulting in a smooth and clear adjustment process in display scenarios, thus improving the user experience.

[0082] Please see Figure 5 , Figure 5 This is a flowchart illustrating a rearview mirror adjustment method provided in an embodiment of the present disclosure, as shown below. Figure 5 As shown, the method provided in this embodiment is executed by a rearview mirror, which can be the rearview mirror in the above embodiments or a processor of the rearview mirror. The method in this embodiment includes: Step 501: Upon receiving a second operation corresponding to the adjustment button or the adjustment sensor of the rearview mirror, enter the field of view adjustment mode.

[0083] The system includes an adjustment button or sensor on the rearview mirror. The second operation is performed on the adjustment button or sensor. The adjustment button can be a physical button, and the second operation can be a press operation received at the adjustment button. The adjustment sensor can be a touch sensor, infrared sensor, pressure sensor, etc., and the second operation can be generated when the sensor's signal reaches a preset range.

[0084] The field-of-view adjustment mode refers to adjusting the position of the viewfinder within the camera's view based on changes in the rearview mirror's orientation, thereby adjusting the rearview mirror's field of view. The viewfinder refers to the area cropped from the camera's view. In this mode, the rearview mirror's field of view can be adjusted based on user input. It can be understood that the camera's field of view is larger than the rearview mirror's; the rearview mirror's field of view is a portion of the camera's field of view, and thus displays that portion of the image. If, during manual adjustment of the rearview mirror, the viewfinder has already moved to the edge of the camera's view, further manual adjustment will not move the viewfinder. Additionally, the system will simultaneously prompt the user that further adjustment of the rearview mirror's field of view is currently impossible, and that manual adjustment of the camera is now permitted.

[0085] In the field of view adjustment mode, perform the following steps 502-504.

[0086] Step 502: Obtain the attitude data of the rearview mirror through the attitude detection module of the rearview mirror.

[0087] Rearview mirrors typically incorporate an attitude detection module, which acquires the mirror's attitude data. This module measures its own attitude to obtain attitude data, which is then used to determine the mirror's attitude. The attitude detection module can be integrated into the rearview mirror's ball joint, allowing the user to manually adjust the view by adjusting the ball joint, and the module can detect changes in the ball joint's attitude.

[0088] Furthermore, the attitude detection module can be a gyroscope.

[0089] Attitude data is used to describe the attitude of an object; the attitude data in this disclosure describes the attitude of a rearview mirror. Attitude data can take many forms. For example, attitude data can be quaternions or Euler angles. Quaternions are commonly used to represent rotational attitude. Euler angles can include pitch angle, roll angle, and yaw angle.

[0090] In this embodiment, the attitude detection module detects the attitude of the rearview mirror and obtains attitude data. For example, the attitude data can be obtained in the form of sampling.

[0091] Step 503: When a change in the posture data of the rearview mirror is detected, adjust the position of the viewfinder in the camera frame according to the change in the posture data of the rearview mirror, so that the field of view of the rearview mirror is adjusted according to the change in the posture of the rearview mirror.

[0092] The changes in the rearview mirror's attitude data are used to indicate changes in the rearview mirror's attitude. The changes in the rearview mirror's attitude data can be obtained by comparing the current attitude data (obtained by the attitude detection module) with the attitude data obtained at the previous sampling time. These changes in attitude data characterize the rearview mirror's attitude changes.

[0093] The first method refers to adjusting the position of the viewfinder so that the field of view of the rearview mirror changes with the attitude of the rearview mirror.

[0094] The video footage was obtained through rearview mirrors and / or the vehicle's cameras.

[0095] Furthermore, a camera can be a webcam.

[0096] The viewfinder is used to crop the camera footage to obtain the displayed image. The viewfinder is a cropped section of the camera footage, containing the image within it. The camera footage is obtained through the rearview mirror and / or the vehicle's camera.

[0097] In this embodiment, after detecting a change in the posture data of the rearview mirror, the position of the viewfinder in the camera frame is adjusted according to the change in posture data in a first manner, thereby adjusting the field of view of the rearview mirror.

[0098] Step 504: Display the view obtained through the viewfinder via the display module of the rearview mirror.

[0099] In this embodiment, during the adjustment of the field of view, the display needs to be shown on the rearview mirror's display module so that the user can check the field of view of the rearview mirror in a timely manner until the field of view is adjusted to a suitable position.

[0100] In practical applications, adjustment buttons or sensors are installed on the rearview mirror. After the rearview mirror is activated, if the user wants to adjust the field of view, they can press the adjustment button or sensor. The rearview mirror receives this second operation from the user and enters the field of view adjustment mode. In the field of view adjustment mode, the attitude detection module in the rearview mirror obtains the attitude data of the mirror's ball joint. The user can then manually adjust the ball joint. The rearview mirror controller responds to this first operation, adjusting the position of the viewfinder in the camera frame according to the first method, thereby adjusting the field of view of the rearview mirror.

[0101] In this embodiment, adjustment buttons or sensors are installed on the rearview mirror. Upon receiving a second operation corresponding to the adjustment button or sensor, the rearview mirror enters a field-of-view adjustment mode. In this mode, the user manually adjusts the rearview mirror, and the mirror adjusts the position of the viewfinder in the camera frame accordingly based on the user's first operation, thereby adjusting the field of view. This reduces the number of buttons on the rearview mirror, improves product stability, and allows for intuitive user operation by triggering the adjustment buttons or sensors and manually adjusting the rearview mirror. This reduces distraction during driving and improves the user experience. Utilizing the existing attitude detection module in the rearview mirror requires minimal modification to the mirror itself, thus reducing costs.

[0102] In some embodiments, step 503 can be implemented by the following steps 5031 and 5032.

[0103] Step 5031: When a change in the attitude data of the rearview mirror is detected, determine the direction and angle information of the rearview mirror adjustment based on the attitude data of the rearview mirror.

[0104] The rearview mirror adjustment direction information indicates the direction of movement of the rearview mirror. The rearview mirror adjustment angle information indicates the angle of movement of the rearview mirror. For example, if a user manually adjusts the ball joint of the rearview mirror downwards by an angle of 'a' degrees, the direction information is downwards, and the angle information is 'a' degrees.

[0105] Step 5032: Adjust the position of the viewfinder in the camera frame according to the direction information, angle information, and adjustment ratio value so that the field of view of the rearview mirror is adjusted according to the change of the rearview mirror's posture.

[0106] The adjustment ratio refers to the ratio of the change in the rearview mirror's posture data to the movement of the viewfinder on the screen.

[0107] Furthermore, the adjustment ratio value is a preset value; or, the adjustment ratio value is a value determined based on the adjustment speed of the rearview mirror and / or changes in the camera's field of view. The adjustment speed value can be either the adjustment speed or the adjustment acceleration. The following is an example of how to obtain the adjustment ratio value.

[0108] In one possible implementation, the adjustment ratio value can be a preset value, for example, an adjustment ratio value that corresponds to the angle information can be preset.

[0109] In another possible implementation, since users may adjust the rearview mirror too quickly or accelerate excessively when manually adjusting it, but do not actually want to adjust the field of vision too much, the adjustment ratio can be determined based on the speed or acceleration of adjusting the rearview mirror during the field of vision adjustment process. For example, when the adjustment speed reaches a preset value, the adjustment ratio can be reduced by a certain percentage from the preset value.

[0110] In another possible implementation, the camera can be mounted on the rearview mirror. For example, on a motorcycle, the camera is usually mounted on the rearview mirror. In the field of view adjustment mode, when the user manually adjusts the rearview mirror, the camera also moves with the rotation of the rearview mirror, and the camera's field of view changes accordingly. In this scenario, the rearview mirror may have rotated a small angle, but it will appear to have moved a lot on the display screen.

[0111] Building upon the three possible implementations described above, a further step is to set a maximum manual adjustment angle for the rearview mirror. Beyond this maximum angle, manual adjustment of the rearview mirror becomes impossible. When the maximum manual adjustment angle is set, the viewfinder moves to the edge of the corresponding camera frame. For example, if the rearview mirror is manually adjusted to its maximum position to the right, the viewfinder will be at the far right of the camera frame.

[0112] The rearview mirror does not have a maximum manual adjustment angle, and can be manually adjusted at any angle. In this case, the position of the viewfinder in the camera frame can be moved accordingly during the manual adjustment of the rearview mirror. Using relative position, as long as the rearview mirror rotates relative to the viewfinder, the field of view of the rearview mirror will shift relative to the viewfinder. This provides a greater degree of freedom.

[0113] In this embodiment, the attitude detection module detects the attitude of the rearview mirror, comparing the current attitude data with the attitude data obtained at the previous sampling time or a previous moment to determine the direction and angle information for adjusting the rearview mirror. By using the direction and angle information of the rearview mirror, along with the adjustment ratio, the movement of the viewfinder within the camera frame can be determined, thereby adjusting the position of the viewfinder within the camera frame. This allows for quick and accurate adjustment of the viewfinder position, resulting in a smooth and clear adjustment process in display scenarios, thus improving the user experience.

[0114] Furthermore, step 5032 can be implemented through the following steps 50321 and 50322.

[0115] Step 50321: Determine the distance the viewfinder should move based on the angle information and the adjustment scale value.

[0116] There can be a linear or non-linear relationship between angle information and the distance the viewfinder moves. The distance the viewfinder moves can be obtained by combining the angle information with the adjustment scale value.

[0117] For example, the distance the viewfinder moves can be obtained according to the following formula (1): Angle information × adjustment ratio = distance the viewfinder moves (1) Step 50322: In the camera frame, adjust the position of the viewfinder in the camera frame according to the direction indicated by the direction information and the distance the viewfinder has moved.

[0118] The direction indicated by the directional information refers to the direction in which the viewfinder moves according to the direction the rearview mirror rotates. For example, if the rearview mirror rotates to the right, the viewfinder will move to the right.

[0119] For example, if a user manually adjusts the rearview mirror's ball joint to the left by an angle of 'a' degrees, with the direction information being left and the angle information being 'a' degrees, and the adjustment ratio is set to 'b', then the viewfinder in the camera's view will be moved to the left by a distance of 'ab' degrees.

[0120] In this embodiment, the distance the viewfinder moves is obtained based on the angle information and the adjustment ratio. In the camera view, the viewfinder is moved in the direction indicated by the direction information, and this distance is recorded. This allows for quick and accurate adjustment of the viewfinder position, resulting in a smooth and clear adjustment process in display processing scenarios, thus improving the user experience.

[0121] In some embodiments, during the field of view adjustment mode, the user needs to be prompted with the current mode. Specific embodiments are described in detail below.

[0122] The method provided in this embodiment may further include the following steps after step 501: Display field of view adjustment instructions via the display module; and / or turn on the field of view adjustment indicator light.

[0123] The field of view adjustment indicator is displayed through the display module to indicate that the view adjustment mode is currently active. This indicator can be text-based, such as "Currently in view adjustment mode" or "Please adjust your view." Alternatively, it can be an icon-based indicator, such as a highlighted icon for view adjustment mode.

[0124] The field-of-view adjustment indicator light is used to indicate whether the field-of-view adjustment mode is currently in effect. The indicator light can be red, yellow, etc., and this disclosure does not limit the color of the indicator light. After the field-of-view adjustment indicator light is turned on, it can remain constantly lit or flash; this disclosure does not limit the flashing of the indicator light either.

[0125] In practical applications, after the rearview mirror enters the field of view adjustment mode, the field of view adjustment instruction information can be displayed on the display module, and / or the field of view adjustment indicator light can be turned on.

[0126] If the display module shows the field of view adjustment indicator to indicate that the user is in field of view adjustment mode, then the field of view adjustment indicator can be displayed in all field of view adjustment modes; alternatively, the field of view adjustment indicator can be displayed when entering field of view adjustment mode.

[0127] If the field of view adjustment indicator light indicates that you are currently in field of view adjustment mode, you can keep the indicator light on or flash continuously in field of view adjustment mode; or you can turn on the field of view adjustment indicator light when entering field of view adjustment mode.

[0128] In this embodiment, by displaying field of view adjustment instruction information and / or turning on the field of view adjustment indicator light in the field of view adjustment mode, the user is prompted that they are currently in the field of view adjustment mode, thereby improving the user experience.

[0129] In some embodiments, the field of view adjustment mode can be exited under various circumstances. The following are exemplary examples of situations in which the field of view adjustment mode can be exited.

[0130] In one possible implementation, the view adjustment mode is exited when no second operation is received.

[0131] In this embodiment, the user continuously triggers the adjustment button or the adjustment sensor to put the rearview mirror into the field of view adjustment mode. When no second operation is received, that is, when the second operation continuously received by the adjustment button or the adjustment sensor stops, the user confirms that they are exiting the field of view adjustment mode.

[0132] In another possible implementation, the view adjustment mode exits after no second operation is received within the first duration. The first duration is a preset duration that can be set according to user habits.

[0133] In this embodiment, the user continuously triggers the adjustment button or the adjustment sensor to put the rearview mirror into the field of view adjustment mode. When no second operation is received within the first time period, that is, when the second operation continuously received by the adjustment button or the adjustment sensor stops for the first time period, the user confirms that they have exited the field of view adjustment mode.

[0134] In another possible implementation, the view adjustment mode exits after the attitude data obtained by the attitude detection module remains unchanged for a second time period. The second time period is a preset duration that can be set according to user habits.

[0135] In this embodiment, after the user triggers the adjustment button or adjusts the sensor, the rearview mirror enters the field of view adjustment mode. The user can manually adjust the field of view by adjusting the rearview mirror. When the attitude data obtained by the attitude detection module does not change within the second time period, it means that the user has not adjusted the rearview mirror within the second time period, and then the user can exit the field of view adjustment mode.

[0136] In another possible implementation, the field of view adjustment mode is exited upon receiving an exit operation via the adjustment button or the corresponding adjustment sensor.

[0137] In this embodiment, after the user triggers the adjustment button or the adjustment sensor, the rearview mirror enters the field of view adjustment mode. The user can manually adjust the field of view of the rearview mirror. After adjusting to a satisfactory field of view, the user can trigger the adjustment button or the adjustment sensor again, and the rearview mirror will exit the field of view adjustment mode.

[0138] In this embodiment, the field of view adjustment mode can be maintained in different ways, and the field of view adjustment mode can be exited after the user adjusts to a satisfactory field of view, thereby saving processing resources and improving the user experience.

[0139] In some embodiments, bumps and other disturbances may occur during vehicle operation, therefore, the rearview mirror needs to be stabilized. That is, when not in view adjustment mode, the rearview mirror typically needs to enter anti-shake mode. Specific embodiments are described below.

[0140] Please see Figure 6 , Figure 6 This is a flowchart illustrating another rearview mirror adjustment method provided in an embodiment of the present disclosure. Figure 5 Based on the illustrated embodiment, the method of this embodiment may further include the following step 601.

[0141] Step 601: In modes other than the field of view adjustment mode, after detecting a change in the rearview mirror's attitude data, adjust the position of the viewfinder in the camera frame according to the second method based on the change in the rearview mirror's attitude data, so that the field of view of the rearview mirror remains unchanged.

[0142] The second method refers to the viewfinder adjustment method that keeps the rearview mirror's field of view constant. The first method differs from the second method.

[0143] In this embodiment, if the viewfinder is not in the field-of-view adjustment mode, for example, after activating the rearview mirror and exiting the field-of-view adjustment mode, it can enter the image stabilization mode. Image stabilization mode refers to maintaining a constant field of view under conditions such as bumps. The viewfinder movement strategy in image stabilization mode is to maintain the field of view as unchanged as possible, similar to gimbal adjustment; even if the handheld angle changes, the orientation remains the same. This is achieved through the camera's wide field of view and cropping. When a change in the rearview mirror's posture data is detected, the position of the viewfinder in the camera's viewfinder is adjusted according to the change in the rearview mirror's posture data to keep the rearview mirror's field of view constant.

[0144] For example, if a user feels that the rearview mirror screen angle is not good after adjusting the field of view, such as being too tilted or having glare, the user can directly adjust the angle of the rearview mirror without pressing the adjustment button or triggering the adjustment sensor. At this time, as the angle of the rearview mirror screen changes, the field of view of the rearview mirror should remain as constant as possible.

[0145] This disclosure provides a rearview mirror, including: a display module, a controller, and an attitude detection module; the controller is connected to both the display module and the attitude detection module.

[0146] The attitude detection module is used to detect the attitude data of the rearview mirror; The controller is used to: respond to a first operation by the user, and adjust the display screen of the rearview mirror according to the direction indicated by the first operation; the first operation includes adjusting the angle of the rearview mirror; the display screen is a portion of the image captured by a camera; the image captured by the camera is obtained through the rearview mirror and / or a camera of the motor vehicle.

[0147] This disclosure provides a motor vehicle that includes a rearview mirror as shown in the embodiment of FIG1 above, or the rearview mirror is used to perform the functions described above.
