The solution of reversing image delay is: 1, and it is replaced by a higher-grade reversing image that supports higher bandwidth; 2. Format the inverted image and reuse it; 3. Upgrade the system. The reversing image is also called parking assistance system, or reversing visual system and vehicle monitoring system. The system is widely used in the field of reversing or driving safety of various large, medium and small vehicles. The reversing image makes the situation behind the car more intuitive and clear when reversing, and it is one of the very practical configurations for reversing safety. When the reverse gear is engaged, the system will automatically turn on the high-definition reversing camera at the rear of the car, and clearly display the situation behind the car on the reversing LCD screen, so as to accurately grasp the road conditions at the rear, and reverse the car as freely and confidently as forward.
