Bus interior high-definition infrared night video USB in car camera

The product is used for

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 .
