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. (SmartViewCtrl1

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.
