4.2.2 Overview of Color Judgement
The Color Judgement application performs inspection to select the color of the object from maximum seven
registered colors. With this application, you can set the area range that the obect within the inspection area is
judged as OK for each product type 1 - 7. In the captured object, the color areas saved as each product type
are sequencitally measured, then the number of the product type which was judged as OK is output.

Operation of AE20
As the figure above, if the object having an unregistered color or an registered color less than the area
value you have set, inspection result “0” is output. This is because the unit judges that the object does not
fulfill the area value saved as each product type no. 1 - 7.
•
If the object having the color saved as multiple product types is judged as OK, the lowest product
type number is output as an inspection result.
•
For Color Judgement, seven product types are executed every time inspection is performed, but
if the number of colors (product types) actually used is less than six, you must also save the
colors (not used for inspection or not captured) and color area (seven colors have been defaultly
saved as a product type for which inspection is not performed. Do not use the preset colors;
otherwise, the product type of the colors may be judged as OK.
