However, the traditional way of outputting images is to transmit the data output by the camera module to the system-level chip (SOC) through SerDes. The data will be processed only after the system-level chip (SOC) is initialized. After that, the system-level chip (SOC) transmits the processed data to the display screen through SerDes. However, since it takes a long time for the system-level chip (SOC) to complete the initialization, the final image output is slow.

[0003] If the image is output in the above-mentioned image output method, it will take at least 4 to 5 seconds from the start of the vehicle-mounted camera to the display on the display screen. This output method takes a long time, which will affect the user experience.

[0041] Combine the following Figure 1 and Figure 2The working process and principle of the fast image output system of the vehicle-mounted camera of the present invention are introduced as follows. The system is provided with two data transmission paths, wherein the first data transmission path is from the camera 101 → the second serializer 102 → the first bridge 8 → the video processing chip 7 → the second bridge 9 → the third serializer 202 → the display screen 201; the second data transmission path is from the camera 101 → the second serializer 102 → the first bridge 8 → the first serializer 3 → the system-level chip (SOC) 5 → the second bridge 9 → the third serializer 202 → the display screen 201. After the system starts working, the corresponding video data is collected through the camera 101 and the video data is transmitted to the second serializer 102; before the system-on-chip (SOC) 5 starts working, it needs to be initialized first, and before the system-on-chip (SOC) 5 is initialized, the power management integrated circuit (PMIC) 4 needs to power the system-on-chip (SOC) 5, and because the power management integrated circuit (PMIC) 4 that powers the system-on-chip (SOC) 5 is controlled by the microcontroller (MCU) 6, before the power management integrated circuit (PMIC) 4 powers the system-on-chip (SOC) 5, the microcontroller (MCU) 6 needs to drive and control the power management integrated circuit (PMIC) 4. It can be seen that the time required for the system-on-chip (SOC) 5 to complete the initialization is relatively long; during the initialization of the system-on-chip (SOC) 5, the microcontroller (MCU) 6 configures the registers of the video processing chip 7, the first bridge 8 and the second bridge 9 through the IIC communication protocol; after the second serializer 102 receives the video data transmitted by the camera 101, the first bridge 8 and the second bridge 9 are connected to the second serializer 102. The second serializer 102 will transmit the received video data to the first bridge 8 through GMSL; after the first bridge 8 receives the video data transmitted by the second serializer 102, the first bridge 8 will transmit the received video data to the video processing chip 7 and the first serializer 3 respectively, wherein, after the first serializer 3 receives the video data transmitted by the first bridge 8, the first serializer 3 will transmit the received video data to the system-on-chip (SOC) 5; after the video processing chip 7 receives the video data transmitted by the first bridge 8, the video processing chip 7 will perform video image processing on the received video data, and after the processing is completed, the video processing chip 7 will transmit the processed video data to the second bridge 9; after the second bridge 9 receives the processed video data transmitted by the video processing chip 7, the second bridge 9 will transmit the received processed video data to the third serializer 202; after the third serializer 202 receives the processed video data transmitted by the second bridge 9, the third serializer 202 will transmit the received processed video data to the display screen 201, thereby completing the rapid image output.After the initialization process of the system-on-chip (SOC) 5 is completed, the system-on-chip (SOC) 5 will perform video image processing on the video data it receives. After the processing is completed, the system-on-chip (SOC) 5 will transmit the processed video data to the second bridge 9; after the second bridge 9 receives the processed video data transmitted by the system-on-chip (SOC) 5, when the second bridge 9 determines that the frequency of the processed video data reaches the preset frequency, the second bridge 9 will switch the data transmission path, that is, switch the data transmission path from the first data transmission path to the second data transmission path, specifically, switch the first data transmission path used by the system-on-chip (SOC) 5 for transmitting video data before the initialization is completed. The system-on-chip (SOC) 5 forms a second data transmission path for transmitting video data after initialization. In addition, in this specific embodiment, the preset frequency is 87 megahertz (MHz), but the preset frequency is not limited to 87 megahertz (MHz), but can be set according to specific circumstances. After the second bridge 9 switches the first data transmission path to the second data transmission path, the second bridge 9 will transmit the processed video data received by the system-on-chip (SOC) 5 to the third serializer 202. After the third serializer 202 receives the processed video data transmitted by the second bridge 9, the third serializer 202 will transmit the received processed video data to the display screen 201, thereby completing the image output.
