3.16 Setting and Reading PRNU Coefficients
You can set or read an individual pixel’s PRNU coefficient.
To set the PRNU coefficient, use the command:
Sy n t ax :
spc i i
Sy ntax Elements:

3.17 Test Patterns and End of Line Sequence
End-of-line Sequence
To alleviate post-pr ocessi ng, Sp y d er 2 offers an end-of-li ne sequence that prov i des basic
calculations including "line counter", "line average", "pixel s above threshold", "pixel s
below thr eshold", and "derivati v e li ne sum". These basic cal cu l ations are the center of
most automatic gain control (AGC) algorithms.
To activate the end-of-line sequence, use the command
els 1. To di sabl e the end-of-line
sequence, use the command
els 0.
