The positioning and resizing of the ROI for the Pattern Match control is different compared to
what we have seen for the other inspection tools. During the setup phase, it is in fact necessary
to define the pattern to be searched inside the image and also the section of the area which has
to be searched.
Select the control by pressing
SET
on the corresponding icon to create two rectangular ROI:
One, in the middle of the focus range, that represents the sample to be searched, the other is as
large as the entire image and constitutes the pattern search area.
Press the
SET
button to modify one or the other area. The edge of the currently selected area will
flash and the label of the ROI will be highlighted in red.
To modify the size of the two ROI, move the cursor to the
Size ROI
icon and then press
SET
. It
is now possible to resize the ROI using the
ARROW
buttons. The sizes of two areas (expressed
in pixels) are displayed on the right side of the screen. Press the
SET
button to modify one or the
other area. The edge of the currently selected area will flash. Once you have achieved the
desired resizing, press the
TEACH
button to return to the Setup menu. If you wish to modify the
ROI positions, select the
Move ROI
from the Setup menu (using the
SET
button again). It is now
possible to move the ROI using the
ARROW
buttons on the keyboard. Once again, to change the
current ROI simply press the
SET
button. To conclude, press
TEACH
to save the modifications.
