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. -- John Robinson Only criminals, tyrants, and cowards have robinson@ac.dal.ca reason to fear the armed, honest citizen. DOD #0069
