CCD and CMOS can be divided into two categories based on the imaging process : fast scan and slow scan It can be divided into specialized level and civilian level according to different application scenarios The common video chat cameras and various digital cameras use civilian grade dynamic and static CCD/CMOS respectively

Various car mounted reverse cameras include : night vision reverse camera license plate frame reverse camera half license plate frame reverse camera perforated camera, external camera etc

There are two types of reverse cameras : wired and wireless The wired method is simple and reliable but it requires wiring inside the vehicle body The wireless method does not require wiring inside the vehicle body and is easy to install, but requires the addition of a wireless receiving module Due to the unsatisfactory reception performance of wireless receiving modules nowadays they are more or less susceptible to interference from the usage environment Generally reverse cameras still use wired methods

The following question is : How can a portable navigation system know that the user is reversing and immediately switch to the rearview function ?

There are three ways :

The first method is a clumsy but also simple and reliable one which is to use the buttons on portable navigation

A certain button can be defined as a reverse rearview switch button Before reversing the user presses this button and the system immediately switches to reverse rearview mode After reversing, press the button again and the system will switch back to its original interface This method is simple and reliable and there is no need to add anything to the extension part of the bracket But it requires manual operation and is not intelligent enough

The second method is to detect the reverse signal (a simple method is to take the control signal from the reverse light) When the user engages the reverse gear the reverse light will light up and provide a switch signal which is used to control the switch of the reverse image system This

method is quite intelligent, with good accuracy and stability

The third method is to continuously check whether the CVBS signal is valid within the written navigation system to determine whether it is reversing When reversing, turn on the reversing camera and the camera will send a CVBS composite video signal to the interior of PND through the bracket interface If PND detects a valid video signal it is considered to be in reverse mode This method can be considered as the most intelligent and accurate method
