The in car camera is the core sensing device of ADAS (Advanced Driver Assistance System) .  Currently   global intelligent driving has ushered in a window of transition from L2 to L3/L4    and the number of cameras installed will increase from 3 - 8 to 8 - 12. According to CINNO Research   the number of cameras installed in passenger cars in the Chinese market will exceed 100 million in 2025   and the compound annual growth rate from 2021 to 2025 will reach CAGR 21% .
At present   in car cameras are mainly divided into front view   surround view   rear view   side view   and built - in cameras .
