NG label
Compare a good criterion image to an objective image by inspecting matching levels
using the garay scale seach function. (Determine whether the port is acceptable or NG by
checking similarities between the criterion image and the workpiece image.)
A matching level comparison using binary images is also possible.

Detect positional deviation of labels , detect contamination of different parts, inspect the mounting
of electronic parts on PC boards, detect mis-print, inspect for missing electric parts such as
terminals, and simple letter inspection.
[Detecting label deviations on packages]
・Inspection procedure
1Conduct a gray scale search of the criterion image position
2Correct the position of the object being measured from the coordinates for the
criterion image obtained in item 1 above.
3If the matching level of the object image is low, the IV-S20 can determine that the
label position is NG.

・Measurement procedure
1Find the center points of criterion images a and b using a two point gray scale search.
2Determine the distance between the two center points.
Register criterion image a and b by matching edges of the IC package.
