Spyder 3 GigE User Manual
Description
Monitor these values (either above or
below threshold) and adjust camera
digital gain and background subtract to
maximize scene contrast. This provides a
basis for automatic gain control (AGC)
Use these values to focus the camera.
Generally, the greater the sum the greater
the image contrast and better the focus.
