Yes, provided that the frame grabber supplier gives you a
photoshop-compatible aquisition plug-in. If you grab 24 bit colour, you
have to process image planes one by one, each for R,G and B. If you have
one of the frame grabbers that is supported by NIH-Image directly, you
don't even need a plug-in.

You program in NIH-Image Pascal macro language and you can access a few
brands of frame grabbers directly, whereas most photoshop-compatible
plugins work as well. It could be as simple as

macro ('grab an image')
begin
  StartCapturing; {The frame grabber starts recording}
  Acquire; {now an image has been recorded}
  SaveAs;{A dialog will come up}
end

and ther you are. Without macro, ofcourse, you can grab images just as well.
