TRIG CCD START
Select a triggering method for the CCD camera
used to capture images. The choices are: "BIN,"
"AVG-GRAYS," "GRAY-SRC," and "EDGE
DTECT."
For details, see page 17-18.
Then the " CCD TRIG COND" line will appear.
CCD TRIG COND
Select the trigger conditions from the sub menu on
this line.
The items in the sub menu will depend on the

Adjust this value the same way you adjusted the
X-axis value.

Description
MAJORITY
Based on the number of pixels in an area, the controller will decide that the whole
area is white if the specified percentage of pixels in that area is white. If the
percentage of white pixels is less than this amount, the area will be treated as
black.
Specify the percentage (%), from 0 to 100% (in units of one percent) in the
"3EVAL-SPEC (RATIO%)" item.
AND Treat as white only when all of the pixels in an area are white.
OR Treat as white if one or more of the pixels in an area is white.
