At this point, the menu illustrated in figure 5-17 appears, although certain items on it may not
appear, depending whether or not you choose splice adjustment.
The top half of this menu screen displays a “boundary Indicator and provides a view of the
scanner current status. The bottom half displays the currently available keyboard commands
for adjusting the merge and splice. If you did choose splice adjustment, all of the items that
follow will appear in the top half of the Merge and Splice Adjustment Menu. If you did not
choose Splice Adjustment, those items marked with an asterisk (*) will not appear.
• Boundary Indicator: This item depicts which two cameras the boundary that you are
currently monitoring lies between.
• Threshold: This field shows the dividing points between marks and media. The range of
possible values is shown to the right.
• Merge: This field shows the number of pixel overlap between the two cameras in the
same axis as the row of the cameras. The range of possible values is showed to the right.
• Splice*: This field shows the number of sampling lines the data is advanced or delayed
to match the ad0jacent cameras in the axis perpendicular to the row of cameras. Again,
the range of possible values is show to the right.
• Delay counts*: This field shows the splice values between each camera in the scanner.
Place the standard test document, illustrated in figure 5-18, in the scanner to demonstrate the
camera merge and splice.
Viewing the scanned image on the monitor, you can operate and manipulate the scanner with
keyboard commands to fine-tune the merge and splice. Any changes you made are instantly
reflected on the monitor in real time. The currently available keyboard commands for
adjusting the merge and splice appear in the bottom half of the Merge and Splice adjustment

• < or , press either these keys to increase the merge.
• > or . press either these keys to increase the merge.
• ( or 9* press either these keys to increase the splice.
• ) or 0* press either these keys to increase the splice.
• Space Bar Press <space bar> to pause or restart the scanner.
• S (speed) Press <S> to set the scanning speed. The speed choices are full, 3/4, or 1/2.
Slower speeds worsen the problem of splicing because they make it easier to detect.
