[0033] Example 1

[0034] As shown in the figure, a method for adjusting the image effect of a vehicle-mounted camera includes the following steps:

[0035] Obtaining a communication protocol between an image sensor, an image signal processor, and a serializer, and setting a deserializer according to the communication protocol;

[0036] Set the image style type of the vehicle camera and store the image style type;

[0037] Get the image style type that needs to be adjusted and call the corresponding image style type;

[0038] The deserializer transmits the data to the serializer through the reverse channel, and configures the called image style type into the image sensor and the image signal processor.

[0039] The working principle of this embodiment:

[0040] First, obtain the communication protocol between the image sensor, image signal processor and serializer. The current mainstream international serial deserializers are ADI's MAXIN and Texas Instruments TI, and the protocols used are GMSL (Gigabit Multimedia Serial Links) and FPD-LINK. Set the deserializer according to the corresponding protocol to ensure that the channel for reverse data transmission can be established.

[0041] Then set the image style type of the vehicle camera and store it to provide a basis for subsequent calls.

[0042] When the image style needs to be adjusted, the image style type that needs to be adjusted is obtained, and the corresponding image style type is called.

[0043] Finally, the deserializer transmits the data to the serializer through the reverse channel, and configures the called image style type into the image sensor and image signal processor, thereby realizing the adjustment of the image style.

[0044] Example 2

[0045] The difference between this embodiment and the first embodiment is that when the image style type is stored, the image style type is stored in the FLASH by means of a register.

[0046] When storing the image style type, the image style type data is stored in the FLASH in the form of a register, which ensures that the image style type data can be saved in the event of a power outage, etc., thereby improving the stability and reliability of the data.

[0047] The working principle of this embodiment is the same as that of Embodiment 1.

[0048] Example 3

[0049] The difference between this embodiment and Embodiment 2 is that when the deserializer transmits the signal to the serializer through the reverse channel, the deserializer transmits the signal to the serializer through the low-frequency reverse channel.

[0050] When transmitting through the reverse channel, a low-frequency reverse channel is used to transmit the signal from the deserializer to the serializer. The low-frequency reverse channel can stably transmit data within a specific frequency range, reducing the possibility of interference and signal attenuation. This method can ensure the quality of the reverse transmission signal, thereby ensuring that the image style type can be accurately configured into the image sensor and image signal processor.

[0051] The working principle of this embodiment is the same as that of Embodiment 1.

[0052] Example 4

[0053] The difference between this embodiment and Embodiment 3 is that the transmission from the deserializer to the serializer is performed by POC single-ended transmission.

[0054] Improve the data transmission method, use POC single-ended transmission to transmit data, and integrate power and data signals on the same line for transmission. This method can reduce the use of cables, simplify the wiring structure, and improve the integration and reliability of the system. At the same time, POC single-ended transmission can reduce costs and improve transmission efficiency.

[0055] The working principle of this embodiment is the same as that of Embodiment 1.

[0056] Example 5

[0057] The difference between this embodiment and embodiment 4 is that the obtaining of the image style type to be adjusted further includes the following steps:

[0058] Get the image style type called by the user, and get the image information taken by the vehicle camera before adjusting the image style;

[0059] Generate an automatic image style type adjustment instruction according to the image style type called by the user and the image information captured by the vehicle camera before adjusting the image style;

[0060] According to the automatic image style type adjustment instruction, the corresponding image style is called.

[0061] When obtaining image information captured by the vehicle-mounted camera before adjusting the image style, image features of the image information, such as color features, texture features, and brightness features, are obtained.

[0062] When generating automatic image style type adjustment instructions, the extracted image features are combined with user requirements to determine specific adjustment parameters. For example, if the color histogram of the image shows that the color saturation is low and the user selects a vivid style, then the adjustment parameters required to increase the color saturation can be determined.

[0063] The working principle of this embodiment is the same as that of Embodiment 1.

[0064] Example 6

[0065] This embodiment is different from Embodiment 5 in that the setting of the image style type of the vehicle-mounted camera includes adjusting the exposure, white balance, brightness, color balance and gamma parameters of the vehicle-mounted camera.

[0066] Adjustment of multiple key parameters enables users to have more precise control over the image style of the vehicle camera. The most suitable image effect can be customized according to different driving environments and personal preferences to improve driving safety and comfort. By adjusting parameters such as exposure and white balance, the vehicle camera can better adapt to different lighting conditions and scene requirements. Whether in daytime, night, sunny, rainy days or special environments such as tunnels, it can provide clear and accurate images to provide better visual reference for drivers. Adjustment of color balance and gamma parameters can make the color of the image more vivid and natural, and the contrast more appropriate. This can not only improve the readability and aesthetics of the image, but also reduce the driver's visual fatigue and enhance the driving pleasure and experience.

[0067] The working principle of this embodiment is the same as that of Embodiment 1.

[0070] The second processing unit is used to set the image style type of the vehicle-mounted camera and store the image style type;

[0071] The third processing unit is used to obtain the image style type that needs to be adjusted and call the corresponding image style type;

[0072] The fourth processing unit is used to transmit the called image style type from the deserializer to the serializer through a reverse channel, and configure the called image style type into the image sensor and the image signal processor.

[0073] Example 8

[0074] A vehicle-mounted camera image effect adjustment device includes a processor and a memory; the memory is used to store program codes and transmit the program codes to the processor;

[0075] The processor is used to execute the steps of the vehicle camera image effect adjustment method described in Examples 1-6 according to the instructions in the program code.
