・Average hue
・Average saturation
・Binary area
・Color degree of match
Purpose
Example
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).
Application
● Inspection of whole of color LCD monitor screen
Detect flaws or dirt on a workpiece that are the same color as was emphasized
using a color filter function.

Measured result
[Inspection procedures]
Binary conversion of the reference image → Register → Measurement
[Measurement results]
・Coordinate of the reference image
・Positional deviation of a workpiece from the reference image.
・Color degree of match
・Edge detection
・Angular deviation
Purpose
Example
Measure the position coordinates of a workpiece with the same extracted color as
the reference color.
Application
Positioning workpieces or parts. Positional deviation inspection.
* Even if the workpiece which has
had the color extracted moves its
position, the controller can
measure the positional coordinate
of this workpiece.
