I am using an Overlay Frame Grabber from Image Technology to grab images
from a composite color camera.  The OFG can digitize frame with resolution 
768x512 256 gray levels.  But the images grabbed haves many dim dark lines.
e.g.
	|||||		/////		/\/\/
	|||||		\\\\\		\/\/\
	|||||		/////		/\/\/

Is it the reason of the resolution of the color camera lower than that of 
the frame grabber?

Is it the reason of grabbing color composite signals using a gray level
frame grabber?

Any comments please? Urgent!
