This appendix provides a quick reference to the 3G-SDI camera configuration
workspace registers.

**To calculate exposure in units of microseconds,
use the calculated line times and minimum
exposures listed in the table below to calculate
the exposure increment or exposure time in the
equations below:
1)
Exposure time = [(1124 – Exposure
increment (Decimal)) *Line Time] + 4 Min
Exposure
To calculate Exposure increment from Exposure
Time:
2)
Exposure Increment = 1124 - (Exposure time
(us) Min Exposure) / Line Time). Convert
Decimal to Hex.
