Manual gain
PIKE cameras are equipped with a gain setting, allowing the gain to be manu-
ally 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 analog
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. (SmartViewCtrl1

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 camera optics and/
or longer shutter settings.
