CSR.

PIKE cameras are equipped with a gain setting, allowing the gain to be man-
ually adjusted on the fly by means of a simple command register write.
The following ranges can be used when manually setting the gain for the ana-
log video signal:
Range
0 ... 565
1 ... 630
0 ... 900
0 ... 900
0 ... 900
0 ... 900
0 ... 670
0 ... 670

Note
• Setting the gain does not change the offset (black
value)
• A higher gain produces greater image noise. This
reduces image quality. For this reason, try first to
increase the brightness, using the aperture of the cam-
era optics and/or longer shutter settings.
