Edge Pitch
When performing measurement using color difference value
Edge level is set using color difference absolute value.
8
Noise Level
This level judges whether an edge is present or not.
The maximum value and minimum value for color difference in the edge detection area are determined
and if the difference is less than the noise level, it is judged that there is no edge. When detection is
affected by noise, increase this value.
(within area)
Maximum value - minimum value of color difference < noise level - edge does not exist - measurement
result is fail
Maximum value - minimum value of color difference > = Noise level - edge exists - targeted for
measurement
Example: When noise level is set to 30
