Hello all,

Among other things, I'm currently trying to get a Video Scope CCD camera to 
work properly with a Frame Grabber board.  I'm driving the whole thing with 
a PC and A-D board.  

When I take a single snap shot, everything works fine.  I get a wonderful 
image.  When I trigger the integration feature on the CCD camera, I get 
flicker.  The flicker comes in two basic flavors, and I understand (or 
think I understand) why it is flickering (the CCD Camera is integrating 
over an odd number of fields in the interlaced image).  What I don't know 
is how to get rid of it.  All attempts to eradicate it to date have been 
unsuccessful.

If anyone out there is using a Video Scope CCD Camera with a Frame Grabber 
board and thinks they can shed some light on how to minimize or ideally 
eradicate the flicker, I would be extreemly grateful.  Thanks.
