of the largest object.) Any red appearing in the objects at this time indicates
isolated regions of the background color, which the system will attempt to
eliminate.
When the background color has been learned, the following message appears
in the message box:
If the background region is acceptable,
select Continue. Otherwise, select Adjust
Color. Select Stop to abort auto–setup.
When the background is “acceptable,” the objects will all be outlined in
green. If the background is not acceptable at this time, pick the
Adjust Color
menu item, then use the Adjust Color menu to adjust the color as required.
Refer to the “ Color menu” in Chapter 3 of the Color CVIM User’s Reference
Manual for information about the color adjustments that you can perform
using the
Adjust Color menu (the two menus provide identical color
adjustment functions).
NOTE: If the background color cannot be adjusted so that the tablets are
outlined in green, pick
Stop to abort the auto setup process at this point and
adjust the lighting to more uniformly illuminate the background. Filtering
(binary morphology) may improve image quality. Refer to the Advanced
Adjustments section, on page 6–12 of Chapter 6, for details about
background color filtering.
When the background color has been properly adjusted, pick Continue to go
to the next step.
Learning Pocket Color (Aluminum Blisters Only)
This section applies only if you selected Enabled in the Aluminum: menu
item. When you pick Continue at this point, the following message appears
in the message box:
Learning pocket color. Areas marked with an X
are sampling positions. De–select any X’s that
are not within a pocket. Select Continue, or
select Stop to abort auto–setup.
The system places an X at two places within each pocket to denote the color
sampling areas. Since the pockets are empty at this time, the two color
samples provide a more accurate calculation of the pocket color than would a
single sample.
When you pick Continue , the system automatically begins the process of
“learning” the pocket color as Color 2 . The term “pocket color” applies to
the color within the pocket, not including the objects (tablets or capsules) or
the background.
