Description

Technical Field

[0001] The present application relates to the field of automotive technology, and in particular to image generation equipment, vehicle-mounted systems, and vehicles. Background Art

[0002] An electronic rearview mirror is an indirect vision device that uses a system consisting of a camera and a monitor to obtain a specified field of view. It incorporates electronic equipment such as a high-definition camera, a digital visual processing system, a safety system, and an LCD display, offering a new type of rearview mirror that can replace traditional optical rearview mirrors. A head-up display (HUD) utilizes optical reflection principles to project information onto the windshield in the form of an image.

[0003] With the continuous development of vehicles and the gradual maturity of related technologies, automobile manufacturers have begun to focus on improving user comfort during driving or riding. Based on this, related technologies have proposed combining electronic rearview mirrors with head-up display systems. This eliminates the displays used in electronic rearview mirror technology to display images on both sides of the vehicle's rear, and instead uses the head-up display system to display these images with a certain degree of transparency on the vehicle's front windshield. While saving the cost of the display, it also eliminates the driver's need to tilt their head left and right to view the electronic rearview mirror display, improving the driver's driving experience.

[0004] However, when the relevant technology realizes the combination of the two, the image signal processor used in the process is still used in conjunction with the left and right electronic rearview mirrors respectively, even though the image signal processor itself has the ability to simultaneously process the images collected by the left and right electronic rearview mirrors. This results in redundant use of the image signal processor and a low degree of integration, resulting in poor portability and compatibility of related components. Utility Model Content

[0005] This application provides an image generation device, a vehicle system, and a vehicle to at least address the component redundancy issue in the integration of an electronic rearview mirror and a head-up display (HUD). The technical solution of this application is as follows:

[0006] According to a first aspect of the present application, an image generation device is provided, comprising an image sensor, a controller, and an image display device. The image sensor is mounted on the exterior of a vehicle to capture an original image of the exterior of the vehicle; the controller comprises a first housing, an image signal processor, and a digital signal processor, both of which are disposed within the first housing; the image sensor is connected to an image signal processor circuit for transmitting an original image to the image signal processor, so that the image signal processor processes the original image to obtain an intermediate image; the image signal processor is connected to a digital signal processor circuit for transmitting an intermediate image to the digital signal processor, so that the digital signal processor further processes the intermediate image to obtain an output image, and transmits the output image to an image display device, so that the image display device displays the output image; and the image display device is connected to the digital signal processor circuit for displaying the output image.

[0007] According to the above technical means, by arranging both the image signal processor and the digital signal processor in the first shell, the image signal processor and the digital signal processor can be integrated into one device, that is, integrated into the controller, so that the controller can uniformly receive the image data transmitted by the image sensor, process it and finally output it as data that can be used by the image display device; compared with the structure in which the image signal processor and the image collector are integrated into one, the redundant use of the image signal processor is avoided and the cost is saved; at the same time, the image signal processor and the digital signal processor are integrated into the controller, and the controller can also process the input data as the original image collected by the image sensor, and can output the output image corresponding to the original image for image display on the image display device, with good mobility and compatibility.

[0008] In one possible embodiment, the image sensor includes a first image sensor and a second image sensor. The first image sensor is connected to an image signal processor circuit and is mounted on the left side of the vehicle to capture a raw image of the left rear of the vehicle. The second image sensor is connected to the image signal processor circuit and is mounted on the right side of the vehicle to capture a raw image of the right rear of the vehicle.

[0009] With this technical approach, compared to a structure where the image signal processor and image acquisition device are integrated, the raw images captured by the first image sensor and the second image sensor are both transmitted to the controller and processed by the image signal processor within the controller. This allows only a single image signal processor to process the raw images captured by multiple image sensors, reducing image signal processor redundancy and significantly saving costs.

[0010] In one possible embodiment, an image display device includes a projection device and a holographic transparent film. The projection device is connected to a digital signal processor circuit and is used to project an output image. The holographic transparent film is located on the light-emitting side of the projection device and is used to optically process the output image projected by the projection device so that the processed output image is projected onto the front windshield of the vehicle.

[0011] According to the above technical means, the holographic transparent film can perform optical processing of interference and diffraction on the output image. In this way, the output image projected by the projection device is processed by the holographic transparent film, so that the final imaging result on the front windshield of the vehicle can ensure both image clarity and sufficient transparency to avoid obstructing the line of sight.

[0012] In one possible embodiment, a projection device includes a second housing, an optical engine, a first polarizer, and a second polarizer. The second housing defines a housing cavity, a first wall of the housing cavity defining a light-transmitting hole communicating with the exterior of the second housing. The optical engine is connected to a digital signal processor circuit, disposed within the housing cavity and connected to the second housing, with the first wall located on a light-emitting side of the optical engine. The first polarizer is connected to the second housing, tilted relative to the first wall, and positioned between the optical engine and the first wall. The second polarizer is connected to the second housing, tilted relative to the first wall, and positioned between the optical engine and the first wall, directly facing the light-transmitting hole. Light emitted by the optical engine can strike the first polarizer, be reflected by the first polarizer to the second polarizer, and then be reflected by the second polarizer to the light-transmitting hole.

[0013] According to the above technical means, through the arrangement of the first polarizer and the second polarizer, the optical path of the light projected by the optical machine can be adjusted so that it can bypass the obstruction of the light projected by the optical machine caused by other components inside the vehicle, thereby improving the flexibility of setting the projection equipment on the vehicle.

[0014] In a possible implementation, the reflection surface of the first polarizer is parallel to the reflection surface of the second polarizer.

[0015] According to the above technical means, the reflection surfaces of the first polarizer and the second polarizer are parallel, so that when the light is reflected by the two polarizers to adjust the light path, the direction of the light reflected by the second polarizer does not change.

[0016] In one possible embodiment, the controller further includes a first serializer and a first deserializer. The first serializer is disposed within the first housing and is connected to the image signal processor circuit; the first deserializer is disposed within the first housing and is connected to the first serializer circuit and to the digital signal processor circuit; wherein: the image signal processor is configured to transmit the intermediate image to the first serializer; the first serializer is configured to convert multiple channels of data representing the intermediate image into first single channels of data and transmit the first single channel of data to the first deserializer; the first deserializer is configured to convert the first single channel of data into first multiple channels of data representing the intermediate image and transmit the first multiple channels of data to the digital signal processor; and the digital signal processor is configured to process the first multiple channels of data to obtain an output image.

[0017] According to the above technical means, compared with the existing technology, the serializer and deserializer are integrated into a single controller, which avoids the difficulty of migrating the controller due to the matching requirements of the serializer and deserializer, and improves the compatibility of the controller.

[0018] In one possible embodiment, the controller further includes a second serializer and a second deserializer. The second serializer is disposed within the first housing and is connected to the digital signal processor circuit; the second deserializer is disposed within the first housing and is connected to the second serializer circuit and to the image display device circuit; wherein: the digital signal processor is configured to transmit the output image to the second serializer; the second serializer is configured to convert multiple channels of data representing the output image into second single channels of data and transmit the second single channels of data to the second deserializer; and the second deserializer is configured to convert the second single channels of data into second multiple channels of data representing the output image and transmit the second multiple channels of data to the image display device.

[0019] According to the above technical means, compared with the existing technology, the serializer and deserializer are integrated into a single controller, which avoids the difficulty of migrating the controller due to the matching requirements of the serializer and deserializer, and improves the compatibility of the controller.

[0020] In a possible implementation, the image generating device further includes a superimposer disposed in the first housing, and the superimposer is connected to the second serializer circuit.

[0021] According to the above technical means, other driving-related information is superimposed on the output image through an overlay device, so that the driver can simultaneously obtain information behind both sides of the vehicle and driving-related information, such as the vehicle's driving speed, navigation information and traffic instructions, through the image display device.

[0022] According to the second aspect provided by the present application, a vehicle system is provided, comprising the above-mentioned image generating device.

[0023] According to the third aspect of the present application, a vehicle is provided, comprising the above-mentioned vehicle-mounted system. Therefore, the above-mentioned technical features of the present application have the following beneficial effects:

[0024] (1) By arranging both the image signal processor and the digital signal processor in the first housing, the image signal processor and the digital signal processor can be integrated into one device, that is, integrated into the controller, so that the controller can uniformly receive the image data transmitted by the image sensor, process it and finally output it as data that can be used by the image display device; compared with the structure in which the image signal processor and the image collector are integrated into one, the redundant use of the image signal processor is avoided and the cost is saved; at the same time, the image signal processor and the digital signal processor are integrated into the controller, and the controller can process the input data as the original image collected by the image sensor, and can output the output image corresponding to the original image for the image display device to display the image, which has good mobility and compatibility.

[0025] (2) Compared to a structure where the image signal processor and image acquisition device are integrated, the raw images captured by the first image sensor and the raw images captured by the second image sensor are transmitted to the controller and processed by the image signal processor within the controller. In this way, only one image signal processor is needed to process the raw images captured by multiple image sensors, reducing the redundancy of the image signal processor and effectively saving costs.

[0026] (3) The holographic transparent film can perform optical processing of interference and diffraction on the output image. In this way, the output image projected by the projection device can be processed by the holographic transparent film so that the final imaging result on the front windshield of the vehicle can ensure both image clarity and sufficient transparency to avoid obstruction of vision.

[0027] (4) By arranging the first polarizer and the second polarizer, the optical path of the light projected by the optical machine can be adjusted so that the light projected by the optical machine is obstructed by other components inside the vehicle, thereby improving the flexibility of the projection equipment in the vehicle.

[0028] (5) The reflecting surfaces of the first polarizer and the second polarizer are parallel, so that when the light is adjusted by the reflection of the two polarizers, the direction of the light reflected by the second polarizer does not change.

[0048] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0049] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0050] Before giving a detailed introduction to the image generating device provided by the present application, a brief introduction to the existing technologies related to the present application is first given.

[0051] Image Signal Processor (ISP): It is the core part of image processing and is mainly responsible for obtaining raw data from the image sensor and performing a series of processing and optimization on this data to produce high-quality image output.

[0052] A digital signal processor (DSP) is a microprocessor dedicated to digital signal processing. It features high speed, high flexibility, and programmability, enabling efficient execution of various digital signal processing algorithms. DSPs play a crucial role in image processing. First, DSPs convert analog image signals into digital signals through sampling and quantization, obtaining a discrete representation of the signal. This step is the foundation of image processing and enables subsequent digital signal processing. Second, DSPs can perform various processing operations on digital image signals, such as filtering, transforms, and encoding / decoding. In image processing, these processes can be used to enhance image quality, improve visual quality, or compress images to conserve storage space. For example, by applying various types of filters, such as mean filtering and Gaussian filtering, effects such as image smoothing, sharpening, and edge enhancement can be achieved. DSPs can also perform image recognition tasks, identifying features such as objects or faces in images through feature extraction and pattern recognition. Finally, DSPs can convert the processed digital image signals back into analog output for subsequent display or storage.

[0053] An on-screen display (OSD), also known as a video display metafile (VDM), overlays information onto the image transmitter. This information includes text, graphics, date, and time. OSD technology allows users to easily view and record scenes and understand relevant image information. Its core function is to overlay text, cursors, and simple images onto images, allowing the display screen to provide users with additional information and offering significant convenience.

[0054] Front-projected Holographic Display: A new type of 3D imaging technology, holographic projection uses interference recording and diffraction reconstruction to restore the 3D image of an object. Holographic projection can project high-fidelity images onto a holographic transparent film, unaffected by ambient light from other directions. Even under strong sunlight, clear images can be formed on the holographic transparent film. The properties of the holographic transparent film can be highly coordinated with the surrounding environment without affecting the existing environment layout. This new interactive display technology combines decorative and practical features and is completely transparent when there is no image.

[0055] An electronic rearview mirror is an indirect vision device that uses a system consisting of a camera and monitor to obtain a specified field of view. It incorporates a high-definition camera, digital visual processing system, safety system, LCD display, and other electronic devices, and is a new type of rearview mirror that can replace traditional optical rearview mirrors.

[0056] A head-up display (HUD) uses optical reflection to project information onto the windshield in the form of images. It uses light and shadow to project driving information, such as speed, navigation information, and traffic signs, onto the windshield directly in front of the driver. This information is readily available to the driver without having to look down at the instrument cluster, providing a safer and more comfortable driving experience.

[0057] With the continuous development of vehicles and the gradual maturity of related technologies, automobile manufacturers have begun to focus on improving user comfort during driving or riding. Based on this, related technologies have proposed combining electronic rearview mirrors with head-up display systems. This eliminates the displays used in electronic rearview mirror technology to display images on both sides of the vehicle's rear, and instead uses the head-up display system to display these images with a certain degree of transparency on the vehicle's front windshield. While saving the cost of the display, it also eliminates the driver's need to tilt their head left and right to view the electronic rearview mirror display, improving the driver's driving experience.

[0058] However, when the relevant technology realizes the combination of the two, the image signal processor used in the process is still used in conjunction with the left and right electronic rearview mirrors respectively, even though the image signal processor itself has the ability to simultaneously process the images collected by the left and right electronic rearview mirrors. This results in redundant use of the image signal processor and a low degree of integration, resulting in poor portability and compatibility of related components.

[0059] Figure 1 The figure shows a structural diagram of the combination of electronic rearview mirror and head-up display system in related technology. Figure 1 ,exist Figure 1 The structure shown includes a left camera, a right camera, a controller, and a head-up display system. The left camera and the right camera each include their own image sensor, image signal processor, and serializer. In one camera, the image sensor collects image data outside the vehicle, transmits it to the image signal processor for processing, and outputs it to the serializer, so that the serializer serializes the image data into a single-channel data and transmits it to the controller through a single-channel circuit connection. The image signal processor itself supports multiple interfaces to connect multiple image sensors and process images input from multiple sources; therefore, in Figure 1 Under the structure shown, there is redundant use of the image signal processor. Figure 1 In the structure shown, the serializers of the cameras on both sides and the deserializer in the controller are placed in different unit devices, which makes the migration and use of the controller difficult or even impossible.

[0060] Figure 2FIG. 1 shows one of the structural diagrams of an image generating device provided by an embodiment of the present application, see FIG. Figure 2 According to the first aspect of the present application, an image generating device is provided, which may include an image sensor 10, a controller 20 and an image display device 300, and the controller 20 may include a first shell 21, an image signal processor 22 and a digital signal processor 23.

[0061] The image sensor 10 is mounted on the exterior of the vehicle, and the image signal processor 22 and the digital signal processor 23 are both disposed within the first housing 21. The image sensor 10 is electrically connected to the image signal processor 22, which is electrically connected to the digital signal processor 23. The image display device 300 is electrically connected to the digital signal processor 23. For example, the image sensor 10 may be an exterior camera including a CMS (Camera Monitor System) camera lens; the image display device 300 may be a device with image display capabilities, such as a display screen or a central control panel.

[0062] In this way, the image sensor 10 can capture the original image outside the vehicle and transmit the original image to the image signal processor 22 for preliminary processing to obtain an intermediate image; the image signal processor 22 then transmits the intermediate image to the digital signal processor 23 for processing to obtain an output image; the digital signal processor 23 transmits the output image to the image display device 300, and finally displays the output image through the image display device 300.

[0063] By arranging both the image signal processor 22 and the digital signal processor 23 in the first shell 21, the image signal processor 22 and the digital signal processor 23 can be integrated into one device, that is, integrated into the controller 20, so that the controller 20 can uniformly receive the image data transmitted by the image sensor 10, process it and finally output it as data that can be used by the image display device; compared with the structure in which the image signal processor and the image collector are integrated into one, the redundant use of the image signal processor is avoided and the cost is saved; at the same time, the image signal processor 22 and the digital signal processor 23 are integrated into the controller 20, and the controller 20 can also process the input data as the original image collected by the image sensor, and can output the output image corresponding to the original image for image display device 30 to display, which has good mobility and compatibility.

[0064] Figure 3 The second structural diagram of the image generating device provided by an embodiment of the present application is shown. Figure 3 In some embodiments, the image sensor 10 may include a first image sensor 11 and a second image sensor 12 .

[0065] The first image sensor 11 is mounted on the left side of the vehicle and is circuit-connected to the image signal processor 22. For example, the first image sensor 11 can be mounted on the left rearview mirror of the vehicle, or on the left A-pillar of the vehicle, or at other locations on the vehicle.

[0066] The second image sensor 12 is mounted on the right side of the vehicle and is electrically connected to the image signal processor 22. For example, the second image sensor 12 can be mounted on the right rearview mirror of the vehicle, or on the right A-pillar of the vehicle, or at other locations on the vehicle.

[0067] In this way, the first image sensor 11 can capture the original image of the left rear of the vehicle, and the second image sensor 12 can capture the original image of the right rear of the vehicle, and they are processed by the controller 20, and finally the images of the left rear and right rear of the vehicle are displayed through the image display device 300.

[0068] With this arrangement, compared to a structure in which the image signal processor and image acquisition device are integrated, the raw images captured by the first image sensor 11 and the raw images captured by the second image sensor 12 are transmitted to the controller 20 and processed by the image signal processor 22 within the controller 20. This allows only one image signal processor to process the raw images captured by multiple image sensors, reducing image signal processor redundancy and effectively saving costs.

[0069] Figure 4 The third structural diagram of the image generating device provided by an embodiment of the present application is shown. Figure 4 In some embodiments, the image display device 300 may include: a projection device 310 and a holographic transparent film 320 .

[0070] The projection device 310 is connected to the digital signal processor 23 circuit, and the holographic transparent film 320 is located on the light-emitting side of the projection device 310 .

[0071] In this way, the digital signal processor 23 can transmit the processed output image to the projection device 310, and the projection device 310 can project the output image onto the holographic transparent film 320. The holographic transparent film 320 can optically process the output image projected by the projection device 310, and finally project the processed output image onto the front windshield of the vehicle.

[0072] It can be understood that the holographic transparent film 320 can perform optical processing of interference and diffraction on the output image. In this way, the output image projected by the projection device 310 can be processed by the holographic transparent film 320 so that the final imaging result on the front windshield of the vehicle can ensure both imaging clarity and sufficient transparency to avoid obstructing the line of sight.

[0073] Figure 5 FIG4 shows a fourth structural diagram of an image generating device provided by an embodiment of the present application, referring to FIG4. Figure 5 In some embodiments, the projection device 310 may include a second housing 311 , an optical engine 312 , a first polarizer 313 , and a second polarizer 314 .

[0074] Among them, the second shell 311 forms a accommodating cavity, and a light-transmitting hole 315 connecting to the outside of the second shell 311 is formed on the first wall of the accommodating cavity; the optical engine 312 is connected to the digital signal processor 23 circuit, the optical engine 312 is arranged in the accommodating cavity, and is connected to the second shell 311, and the first wall is located on the light-emitting side of the optical engine 312; the first polarizer 313 is connected to the second shell 311, and the first polarizer 313 is tilted relative to the first wall, and is located between the optical engine 312 and the first wall; the second polarizer 314 is connected to the second shell 311, and is tilted relative to the first wall, and is located between the optical engine 312 and the first wall, and is opposite to the light-transmitting hole 315; the light emitted by the optical engine 312 can irradiate the first polarizer 313, and is reflected by the first polarizer 313 to the second polarizer 314, and then reflected by the second polarizer 314 to the light-transmitting hole 315.

[0075] In this way, the light emitted by the optical machine 312 can be irradiated to the first polarizer 313, and then reflected by the second polarizer 314 set after the first polarizer 313, and then reflected by the second polarizer 314 to the light transmission hole 315, and finally pass through the light transmission hole 315 to be projected onto the holographic transparent film.

[0076] It can be understood that by arranging the first polarizer 313 and the second polarizer 314, the optical path of the light projected by the optical machine 312 can be adjusted so that it can bypass the obstruction of the light projected by the optical machine due to other components inside the vehicle, thereby improving the flexibility of setting the projection device 310 on the vehicle.

[0077] In some embodiments, a reflective surface of the first polarizer 313 is parallel to a reflective surface of the second polarizer 314 .

[0078] It can be understood that the reflection surfaces of the first polarizer 313 and the second polarizer 314 are parallel, so that when the light is reflected by the two polarizers to adjust the light path, the direction of the light reflected by the second polarizer does not change.

[0079] It should be noted that the reflective surface of the first polarizer is arranged opposite to the reflective surface of the second polarizer, and the reflective surface of the first polarizer faces the light outlet of the optical machine, so that the light projected by the optical machine can be reflected between the first polarizer and the second polarizer.

[0080] In some embodiments, the reflection surface of the first polarizer 313 is not parallel to the reflection surface of the second polarizer 314 .

[0081] In some embodiments, the angle between the reflective surface of the first polarizer 313 and the first wall surface is greater than 0° and less than 90°. For example, the angle between the reflective surface of the first polarizer 313 and the first wall surface can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc.

[0082] In some embodiments, the angle between the reflective surface of the second polarizer 314 and the first wall surface is greater than 0° and less than 90°. For example, the angle between the reflective surface of the second polarizer 314 and the first wall surface can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, etc.

[0083] In some embodiments, the projection device may further include a first motor, the output shaft of the first motor being connected to the first polarizer 313, and the first motor being able to drive the first polarizer 313 to rotate to adjust the angle between the reflecting surface of the first polarizer 313 and the first wall surface, thereby adjusting the light path of the light projected by the optical machine 312 when reflected by the first polarizer 313 and the second polarizer 314, and further adjusting the projection position of the light on the front windshield.

[0084] It should be noted that the rotation axis of the first polarizer 313 is perpendicular to the thickness of the first polarizer 313 and perpendicular to the arrangement direction of the first polarizer 313 and the second polarizer 314. The rotation angle range of the first polarizer 313 must be sufficient to ensure that light incident on it can be reflected by the second polarizer 314 and pass through the light transmission hole 315 after being reflected by the second polarizer 314.

[0086] It should be noted that the rotation axis of the second polarizer 314 is perpendicular to the thickness direction of the second polarizer 314 and perpendicular to the arrangement direction of the first polarizer 313 and the second polarizer 314. The rotation angle range of the second polarizer 314 must meet the requirements of ensuring that light reflected by the first polarizer 313 can be irradiated by the second polarizer 314, and light irradiated by the second polarizer 314 can pass through the light transmission hole 315 after being reflected by the second polarizer 314.

[0087] Figure 6 FIG5 shows a fifth structural diagram of an image generating device provided by an embodiment of the present application, referring to FIG5. Figure 6 In some embodiments, the controller 20 may further include a first serializer 24 and a first deserializer 25 .

[0088] Among them, the first serializer 24 is arranged in the first shell 21, and the first serializer 24 is circuit-connected to the image signal processor 22; the first deserializer 25 is arranged in the first shell 21, and the first deserializer 25 is circuit-connected to the first serializer 24 and the digital signal processor 23.

[0089] In this way, the image signal processor 22 can transmit the intermediate image to the first serializer 24. After the first serializer 24 performs serialization processing on it (serializing the disordered parallel multi-channel data into single-channel data), it is transmitted to the first deserializer 25 for processing (dividing the single-channel data into multi-channel data according to preset rules) to obtain an intermediate image that conforms to the input data format of the digital signal processor 23, so that the digital signal processor 23 can process the intermediate image to obtain an output image.

[0090] It can be understood that, compared with the existing technology, integrating the serializer and deserializer into a single controller avoids the difficulty of migrating the controller due to the matching requirements of the serializer and deserializer, thereby improving the compatibility of the controller.

[0091] Figure 7 FIG6 shows a sixth structural diagram of an image generating device provided by an embodiment of the present application, referring to FIG6. Figure 7 In some embodiments, the controller 20 may further include a second serializer 26 and a second deserializer 27 .

[0092] The second serializer 26 is disposed in the first housing 21 and is connected to the digital signal processor 23 . The second deserializer 27 is disposed in the first housing 21 and is connected to the second serializer 26 and the image display device 300 .

[0093] In this way, the digital signal processor 23 can transmit the intermediate image to the second serializer 26. After the second serializer 26 performs serialization processing on it (serializing the disordered parallel multi-channel data into single-channel data), it is transmitted to the second deserializer 27 for processing (dividing the single-channel data into multi-channel data according to preset rules) to obtain output data that conforms to the input data format of the image display device 300, so that the image display device 300 can display the output image.

[0094] It can be understood that, compared with the existing technology, integrating the serializer and deserializer into a single controller avoids the difficulty of migrating the controller due to the matching requirements of the serializer and deserializer, thereby improving the compatibility of the controller.

[0095] Figure 8 FIG7 shows a structural diagram of an image generating device provided by an embodiment of the present application, see FIG7. Figure 8 In some embodiments, the image generating device may further include a superimposer 40 .

[0096] The adder 40 is disposed in the first housing 21 , and the adder 40 is circuit-connected to the second serializer 26 .

[0097] In this way, other information to be displayed can be input into the second serializer 26 via the superimposer 40. The second serializer 26 then serializes the intermediate image and this information together, and transmits it to the second deserializer 27 and other devices. Ultimately, the output image displayed by the image display device 300 includes the image captured by the image sensor 10 and the information superimposed by the superimposer. This information may include vehicle speed, navigation information, and traffic signs.

[0098] In this way, other driving-related information is superimposed on the output image through the superimposer 40, so that the driver can simultaneously obtain information behind both sides of the vehicle and driving-related information, such as the vehicle's driving speed, navigation information and traffic instructions, through the image display device.

[0099] According to the second aspect of the present application, a vehicle-mounted system is provided, which includes the above-mentioned image generating device. The advantages possessed by the above-mentioned image generating device are also possessed by the vehicle-mounted system provided by the present application, and will not be repeated here.

[0100] According to the third aspect of the present application, a vehicle is provided, which includes the above-mentioned vehicle-machine system. The advantages possessed by the image generating device mentioned above are also possessed by the vehicle provided in the present application, which will not be repeated here.

[0101] Figure 9 A schematic diagram of a partial structure of an image generating device and a vehicle provided by the present application is shown. Figure 9The vehicle includes: a windshield 901 , a dashboard 902 , a steering wheel 903 , a steering motor 904 , a steering mechanism 905 and an image display device 300 .

[0102] The image display device includes a projection device 310 and a holographic transparent film 320. The projection device 310 includes a second housing 311, an optical engine 312, a first polarizer 313, a second polarizer 314, and a light-transmitting hole 315.

[0103] It should be noted that in Figure 9 In the figure, the arrowed lines represent the optical paths of the light projected by the optical engine 312 for displaying the image. Point M in the figure represents the position of the driver's eyes when the driver or passenger is seated in a normal position in the vehicle. This is shown in the figure for ease of explanation and to facilitate understanding of the operating principles of the image generation device provided herein.

[0104] according to Figure 9 As can be seen, the projection device 310 is disposed in the instrument panel of the vehicle. In addition, a mounting hole is provided on the instrument panel, and the holographic transparent film 320 is connected to the mounting hole.

[0105] The projection device is electrically connected to a controller 20 installed in the vehicle. The controller 20 is electrically connected to a first image sensor 11 located on the left side of the vehicle and a second image sensor 12 located on the right side of the vehicle. Thus, the image sensor 10 can capture a raw image from behind the vehicle. The raw image is then processed by the controller 20 to produce an output image, which is then transmitted to the optical engine 312 of the projection device. The optical engine 312 processes the data representing the output image and ultimately projects the output image externally in the form of light. After reflection and adjustment by the first polarizer 313 and the second polarizer 314, the light's optical path is adjusted, and the light is ultimately emitted through the light-transmitting hole 315 onto the holographic transparent film 320. After optical processing by the holographic transparent film 320, the light is ultimately projected onto the windshield 901.
