It sounds like you are trying to analyze the video signal rather than acquire and analyze an image. If this is the case, you might consider re-posting this question under the Measurement Hardware category (perhaps in the High-Speed Digitizer or Multifunction DAQ sub-categories). I would also recommend contacting a Technical Sales Representative, at 1-888-280-7645, for assistance configuring a system specific to your needs.
