KEY FEATURES
    View-DR.
View-DR technology from Sony offers an extremely wide 
dynamic range. 
View-DR is a combination of Sony’s  
full-capture Wide-D technology, the  
high-speed ‘Exmor’ CMOS sensor and 
Visibility Enhancer (VE). The full-capture 
Wide-D technology captures images  
using a 'standard' exposure time and  
takes either one or three images using  
very short exposure times depending on 
the camera type. The newly developed 
View-DR algorithm nearly doubles the 
camera's sensitivity when compared to 
conventional Wide-D technologies.  
To capture multiple HD resolution images 
at a very high speed, the ‘Exmor’ CMOS 
sensor utilises its high-speed readout 
characteristics. When combining multiple 
images, VE is employed to provide a high 
level of chrominance and luminance. With 
View-DR, monitored images become very 
visible; even more so than when viewed 
with the naked eye.
One image is taken using a standard 
exposure time and either one or three 
images are taken using very short
exposure times, depending on the 
camera type.
(This illustration shows one standard 
exposure time and three very short 
exposure times.)
