Screen Display When the Edge Level and Noise Level Are Changing
A bar showing the threshold level moves up and down on the graphic as the edge level/noise level value changes.
A cross-key cursor will also appear at the detected edge position.

Description
Noise level
Sensors with Color Cam-
eras Only
Range: 0 to 422
Default: 5
(Sensors with Mono-
chrome Cameras only)
Range: 0 to 255
Default:128
Sets the density level to be considered as noise.
If the difference between the maximum and minimum color changes in the
region is below the noise level, it will be assumed that there is no edge.
Increase this value if noise is incorrectly detected as an edge.
If you change the noise level, perform teaching again.
Noise threshold
The maximum and minimum color deviations and densities within the edge detection region are determined.
If the difference is less than the noise threshold, it is assumed that there are no edges. Normally there is no
problem with the default value of 10, but if noise is mistakenly detected as an edge, make this value higher.
