CCD universal bus mirror car mounted monitoring truck harvester reverse waterproof rear view car mounted camera

industrial structure
Car mounted cameras are mainly divided into three markets :  upstream  midstream   and downstream
The optical lenses and lens module packaging in the midstream play an important role in the automotive camera industry chain  The optical lens is composed of upstream optical lenses   filters, and protective films  CMOS image sensors are composed of upstream chip design factories   wafer manufacturing factories   and packaging and testing factories
Optical lenses   adhesive materials   and joint lens module packaging   combined with integrated downstream car mounted camera products  
At present   the main manufacturers of car mounted camera integration include   Lens module packaging factory

For mobile phone cameras   the main purpose is to achieve high imaging quality   But for car mounted cameras   stability   frame rate   reliability   and other factors are particularly important    Therefore  compared to traditional industrial cameras and mobile phone cameras   the working environment of in car cameras poses strict requirements for products   requiring cameras to ensure working conditions in high and low temperatures   strong and low light   humid and hot weather   extreme weather and other environments   In addition   pixel upgrades   high dynamics   etc  are also the focus of attention

Specifically    in car cameras require a temperature range of  - 40 ~ 80 ℃   extremely high anti magnetic  seismic    and waterproof properties  with a service life of 8 - 10 years or more  The camera pixels are moving from 300000 to 1 million pixels  and high dynamic requirements require the camera to ensure effective use when light changes frequently   In addition    the certification cycle for in car cameras is long and industry barriers are high
