Stabilizing the Judgment Process
Correcting the distorted images due to
the installation
If the sensor is not installed just in front of the target
due to the sensor installation restrictions and/or to
prevent a shine on the target’s surface, the target
image may become trapezoidally distorted.
The tilt correction corrects these images and
displays them without distortion.

Achieving adequate image brightness
If the image is too dark, the judgment process for
high and low-quality-targets becomes unstable due
to poor contrast. Also, if the image is too bright,
the judgment process may become unstable.
Brightness can be adjusted in Auto Brightness
Adjustment.
“Auto Brightness Adjustment” (Page 4-11)
