There are a few comparators available, some manual, some automatic. Some
switch between images quickly making any differences stand out, others
actually display a 'difference image' which highlights differences between
the boards.
The golden image is usually stored electronically - one of the better ones I
have seen in manufactured by Diagnosys and I think was called Viewpoint. It
actually used a scanner to take an image of the board!!
They have a Web Site at www.diagnosys.com
