Description

Technical Field

[0001] This application relates to the field of display control technology, specifically to a camera module and camera device. Background Technology

[0002] As automobiles become increasingly intelligent, the requirements for safety performance are becoming more stringent. Monitoring the operation of internal vehicle functions and the driver's driving status through built-in cameras provides a reference for safe driving.

[0003] Currently, a serializer, deserializer, and coaxial cable are typically used to connect the motherboard controller and the image sensor module. By configuring and initializing the serializer, deserializer, and image sensor, the image data signal acquired by the image sensor module is transmitted to the serializer. The serializer then connects to the coaxial cable, processes the received image data signal through the deserializer, and transmits the information to the motherboard controller for further processing. The motherboard controller then sends the processed data to the next higher-level controller for use in intelligent driving systems, or controls an external display to show the acquired image data as required. Because the distance between the serializer / image sensor and the deserializer is relatively long, long-distance image data transmission is easily affected by external signal interference. Furthermore, the long transmission distance also increases the initialization time of the serializer and image sensor module, negatively impacting both data transmission and initialization efficiency.
