11.1 Gray Scale Edge Checkers
Gray scale edge checkers use gray scale processing for precision detection of changes
in gray scale (outlines, boundaries, etc.). They are capable of detecting edge
coordinates with sub−pixel precision. They can also judge whether or not a product is
OK on the basis of the number of objects detected.
Up to 256 edges can be detected. (However, only up to 99 gray scale edge checkers
can be used for numerical calculation.)
You can set up to 32 checkers per type.
