[0023] Please refer to the attached Figure 1 The embodiment of the utility model proposes an electronic mirror mainboard suitable for a variety of camera devices, the electronic mirror mainboard includes a video encoding module, a VPSS preprocessing module, a central processing unit module, a display driver module and a video storage module, the electronic mirror mainboard is provided with a plurality of camera device interfaces, the plurality of camera device interfaces are used for connecting corresponding external camera devices, each of the camera device interfaces is respectively connected to a signal adapter board, the video encoding module is connected to each of the signal adapter boards through a connector, the video encoding module is connected to the VPSS preprocessing module, the VPSS preprocessing module is connected to the display driver module, the display driver module is connected to a plurality of video output interfaces, and the central processing unit module is respectively connected to the video encoding module, the VPSS preprocessing module, the display driver module and the video storage module.

[0024] It can be understood that the working principle of the utility model is: a signal adapter board is connected to each camera device interface, and these signal adapter boards play the role of signal conversion and transmission, and transmit the signal of the external camera device to the video encoding module on the electronic mirror main board, so that the electronic mirror main board can be applied to a variety of different external camera devices, reduce costs, and be easy to use. The video encoding module is responsible for receiving the video signal transmitted from the camera device interface through the signal adapter board, and performing compression encoding processing. The VPSS preprocessing module receives the video signal from the video encoding module and performs preprocessing work, such as noise reduction, deblurring, color correction, etc., to improve the video quality. The display driver module is connected with multiple video output interfaces and is responsible for transmitting the preprocessed video signal to the external display device for display. The video storage module is used to store and backup the video data in this process.

[0025] The number of camera device interfaces and signal adapter boards can be set according to actual needs, and is set to three in this embodiment.

[0026] In one embodiment of the present utility model, the electronic mirror mainboard further includes a wireless transmission management module, and the wireless transmission management module is connected to the video encoding module.

[0027] It is understandable that the wireless transmission management module can connect to the video encoding module to transmit the encoded video signal to other devices through the wireless network to achieve remote functions.

[0028] In this embodiment, the VPSS preprocessing module includes an image denoising unit, an image sharpening unit and a color correction unit.

[0029] It can be understood that the image denoising unit is used to process the image signal collected by the camera, remove noise in the image, and improve the image quality; the image sharpening unit can enhance the edges and details of the image to make the image clearer and vivid; the color correction unit is used to adjust the color and tone of the image to ensure the accuracy and authenticity of the image display.

[0030] In this embodiment, the external camera device includes one or more of OV6946, OV2740, OV9734, OV5640, and OV8865. Of course, other types of camera devices may also be included, and this embodiment does not make specific limitations.

[0032] It can be understood that the main function of the encryption module is to encrypt the data processed by the video encoding module to ensure the security and confidentiality of the video data during wireless transmission.

[0033] Specifically, the encryption module encrypts the video data to prevent the data from being stolen or tampered with by unauthorized users during wireless transmission. By placing the encryption module between the wireless transmission management module and the video encoding module, the data can be encrypted immediately after the video data encoding is completed, ensuring that the encrypted data is transmitted to the wireless network, thereby improving the security of data transmission.

[0034] In an embodiment of the present invention, a connection indicator light is provided at each camera device interface position.

As a liquid crystal display driver chip, HT1621B has the advantages of low power consumption, high integration, strong programmability, multiple display modes, strong anti-interference ability, stable and reliable operation, etc.

[0038] Furthermore, the plurality of video output interfaces include at least any two interface formats among HDMI interface, DVI interface, VGA interface, and SDI interface formats.

[0039] HDMI (High Definition Multimedia Interface) is a digital video / audio interface technology. VGA (Video Graphics Array) is a video transmission standard introduced by IBM in 1987 along with the PS / 2 machine. SDI (Serial Digital Interface) is a professional digital video interface.

[0040] It is understandable that by including any two of the four different types of video output interfaces, the requirements for connecting various types of display devices can be met, providing wider compatibility and flexibility. Users can select the appropriate video output interface according to specific needs to achieve the best video output effect.

[0041] In this embodiment, the electronic mirror mainboard further includes a power management module, and the power management module is used to supply power to the electronic mirror mainboard.

[0042] It is understandable that the power management module generally includes components such as a power input interface, a voltage stabilizing circuit, and a power output interface. Through these components, the power management module can filter, stabilize, and protect the input power to ensure that the power supplied to the electronic mirror mainboard is stable and reliable, and avoid voltage fluctuations or power interference from affecting the system.
