Detect flaws or dirt on a workpiece that color was emphasized using a color filter
function.(Using a gray search function after filtering a color, the controller detects
cells having the maximum density and minimum density in the search area. It can
measure the maximum density difference with all of the area (total difference), a
position that has maximum density difference with an adjacent cell (adjacent
difference).
Detect flaws or dirt on a workpiece that are the same color as was emphasized
using a color filter function.
