Manual gain
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:
The increment length is ~0.0353 dB/step.
The increment length for the PIKE F-145B/C is ~0.0358 dB/step.
The increment length for the PIKE F-145B/C-15fps is ~0.0358 dB/step.
The increment length for the PIKE F-505B/C is ~0.0359 dB/step.
Brightness (black level or offset)
It is possible to set the black level in the camera within the following ranges:
0 ... +16 gray values (@ 8 bit)
Increments are in 1/16 LSB (@ 8 bit)
Type Range Range in dB
PIKE color cameras 0 ... 565 0 ... 20 dB
PIKE b/w cameras 1 ... 630 0 ... 22 dB
PIKE F-145B 0 ... 900 0 ... 32 dB
PIKE F-145C 0 ... 900 0 ... 32 dB
PIKE F-145B-15fps 0 ... 900 0 ... 32 dB
PIKE F-145C-15fps 0 ... 900 0 ... 32 dB
PIKE F-505B 0 ... 670 0 ... 24 dB
PIKE F-505C 0 ... 670 0 ... 24 dB

Note
L
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.
