10.5.2      High dynamic range mode       

In this mode, high dynamic range can be achieved by setting a different exposure time for each 
sensor. To use this mode, set the sync mode 

to ―High dynamic range

 1, 2, or 3

‖.

 

The combining of the two signals uses the ratio of the shutter value for each sensor as the 
coefficient. As the composition process can be done regardless of signal levels, the composed 
signal is visibly smooth.   
There are three built-in High Dynamic Range modes: 
 

 

High dynamic range 1

 

 

In this mode, the ratio of camera 0 video signal is larger than that of camera 1.

High dynamic range 2 

In this mode, 50% of each video level is added to make an output.
