When we buy a car, some vehicles do not have a standard reversing image. To choose an option, this option is not cheap. Thousands of them are definitely needed. I would like to dress a reversing camera, reversing will be able to see high-definition screen, and more convenient for novices, but it is true that we will mention the car that will find that the quality of these reversing cameras is just like the product of the last century, color distortion does not say, The sharpness is still very low, and some may not even reach the clarity of DVD quality.
So did we really pay for it? These picture quality is worse than the front camera of the mobile phone, and there is no manufacturer to solve it.
Work environment We all know that these cameras are really electronic products? Electronic products have characteristics and are very fragile. It is hard to see that many people have broken their mobile phones and broken their computers every year for various reasons. Electronic products are afraid of harsh environments. The environment is so bad that they can go wrong at any time and even hang up.
But everybody thinks about where to install the reversing camera? Underneath the rear license plate, the car ran on the road. It was basically a wind and rain, splashing mud from time to time. Under this working condition, the first task for the reversing camera is not the image quality but stability.
In order to ensure stable operation of the camera in any environment, all components of the camera will be very large, and the entire camera is densely covered with heat sinks and sealing devices in order to ensure maximum stability.
The quality of the picture is really not important to ensure that after the stable operation, there is not much space left for the picture quality. We all know that if a camera is to achieve higher quality, it will inevitably have a more complex structure and will have more heat. The complexity of the structure and the amount of heat generated in the reversing camera are strictly limited. Therefore, for the sake of stability, the image quality and clarity can only be compromised. As a result of the final compromise, the quality of the reversing camera is only visible. Clearly.
