5. Calculate the values RGe and Xe for the even channel using the same method as in steps 1,
2, 3, and 4. Use the decimal values of Byte 8 to Byte 5 to determine the even pixel reference
gain RGe. RGe is 111.40 in this example, the value for Xe is 4.97.
6. Convert the results to decimal using the appropriate formula a) or b):
a)
Odd pixel gain setting
b)
Odd pixel gain setting
Since Xo is 4.9 and thus definitely less than 14.27, we need formula a):
a) Odd pixel gain setting
Odd pixel gain setting = 180.8. Round to 181.
7. Calculate the even gain setting in the same way. It is 183 in this example.
8. Convert the results to hexadecimal:
9. Use the odd pixel gain and even pixel gain binary commands to set the odd and even gain to
the calculated values.
After you use the commands to enter the calculated values, the camera will be operating at 2 dB
with respect to the master camera. The odd and even pixels will be balanced.
You may get a better odd/even match by increasing or decreasing either the odd or the
even gain by one.
Since the black level is very stable, you do not need to adjust the offset when you
change the gain.
