1) Improves signal output swing after a background subtract.
When subtracting a digital value from the digital video signal,
using the command, the output can no longer reach its
ssb
maximum. Use this command to correct for this where:
max output value
ssg value =
max output value - ssb value
2) Increases/decreases the camera's responsivity by
increasing/decreasing the digital gain.
digital gain below 1 will result in the camera not reaching 1023
DN.
ssg t i
t
Sensor tap selection. Allowable range is 1 to 2, or 0 for all
taps.
i
Gain setting. The gain ranges are 0 to 65535. The digital
video values are multiplied by this value where:
i
D igital G ain=
4096
For example, to set a digital gain of 1.0, i equals 4096.
•
Entering a large value gain will cause the camera to digitally
saturate the output image
•
Entering a zero value gain will cause the camera to force the
pixels in the designated tap to be 0 DN
•
Entering a value less than 4096 will cause the camera to not
be able to digitally saturate
