Analog vs. Digital

An analog camera delivers the signal representing the observed image in the form of an analog signal, named the video signal. The analog signal incorporates several features aimed at providing timing information for the frame grabber to synchronize on it.

Domino frame grabbers are able to interface to industrial analog cameras, while Picolo frame grabbers are able to interface to standard analog cameras.

A digital camera delivers the signal representing the observed image in the form of a digital signal. The luminance signal can be coded on 8 to 12 bits, and transmitted to the frame grabber through a digital data link.

Grablink frame grabbers are able to interface to industrial digital cameras based on the Camera Link standard.
