A comparative calculation between images, gray level changes, and space filter are available for image
pre-processing.
How to get to the "IMG PRE-PROC" screen
Select "OBJECT TYPE COND" and then "TYPE00"
or "TYPE(NEW)" on the "MAIN COND" screen.
Then select "MEA-CND(CAMERA1)" and "MEAS"

SELECTION" item, press the SET key and choose
a measurement program from the popup menu.
Note: If the " MEAS SELECTION" is set to "NO,"
the image pre-processing cannot be speci-
fied.
Press the ESC key to return to the OBJECT TYPE
