Compared with common cameras, WDR (Wide Dynamic
Rang) can revert to filmed image more correctly. If the filmed
region has a large contrast, stronger bright covers a large
area of filmed region, common camera's electronic shutter
will work in a higher speed after lighting, at the same time,
dark region will be darker, even black, on the contrary, If
the dark covers a larger area, common cameras' electronic
shutter will work in a low speed, at this time, bright area will
over-exposure, resulting in a white and can not be resolved.
WDR cameras is using some kind technologies, making dark
in the light of different circumstances can reproduce the
brightest objects, also can reproduce the dark objects.
In some complex environment, common cameras film
some objects, only to give up.
