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:
Note
•
Values can only be changed within the limits of gain
CSR.
•
Changes in auto exposure register only have an effect
when auto gain is active.
•
Auto exposure limits are 50..205. (

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.
