Description of the data path
Manual gain
Pike cameras are equipped with a gain setting, allowing the gain to be
manually
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. (

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.
