The built - in camera is mainly used to monitor the status of drivers or passengers   realizing functions such as DMS driver monitoring system and OMS member monitoring system extended on the basis of DMS .

The hardware structure of car mounted cameras mainly includes optical lenses   image sensors (CIS)   image signal processors (ISP)  serializers   connectors  etc  .

When the car mounted camera starts working   the light will pass through the lens   convert the light signal into an electrical signal through an image sensor  and then convert it into a digital image signal through an A/D (analog - to - digital converter)   which is then color corrected by an ISP (image signal processor)

After a series of processing such as noise reduction  the processed image data is transmitted to the central processing unit through a serializer   etc . The connector is mainly used to fix the camera .

From a cost perspective   image sensors (CIS) have the highest cost   accounting for approximately 52% of the camera's total cost   Next is optical lenses   accounting for 20%  The cost of module packaging is not significantly different from that of lenses   at 19%   The three account for over 90% of camera costs

Car mounted cameras are mainly divided into three markets :  upstream   midstream   and downstream  .
The optical lenses   CIS   DSP (ISP)   and lens module packaging in the midstream play important roles in the automotive camera industry chain . The optical lens is composed of upstream optical lenses  filters, and protective film   CMOS image sensors (CIS) are composed of upstream chip design factories   wafer manufacturing factories   and packaging and testing factories  .
Optical lenses   adhesive materials   and CIS are combined for lens module packaging    and then integrated with DSP (ISP) to downstream in car camera products  .
