Camera Properties Window
On the Camera tab, Click Lens to open the Camera Properties window. This window provides settings for adjusting
the camera image quality to achieve the sharpest and most useful image.
These parameter values increment or
decrement as you move a slider.
Camera Properties Window Section Function

Exposure Controls the amount of light per unit area that reaches the camera.
Gain
Changes the apparent brightness and light-sensitivity of the camera image at a given
exposure.

Defines the relationship between a pixel’s numeric value and its actual luminance.
Pan Moves the visible image horizontally and vertically.
Shutter Adjusts the level of light entering the camera.

the current Lens settings.
Load Setting
Allows you to load the Lens settings from a saved *.ccd file. When the settings are
loaded, click SAVE to make them the current settings.
Auto
Attempts to generate the most optimal settings depending on the amount of light
present. Clicking the checkbox next to the property indicated (Exposure, Gain, or
Shutter) locks that property so that it cannot be edited using the slider. However, these
settings can be adjusted by the system when you click the AUTO button regardless of
whether they are locked.

Template Match and Area Windows
Once a mark is stored in the Mark Library, you can right-click on the mark image cell and select PROPERTY to open
the Template Match window. The Template Match window provides access to the Area window, which is used to
fine-tune how the camera evaluates a mark.
Template Match Area Window Section Function
Origin
Displays the open mark image.
Gray Displays the gray rating for the selected point in the original image. When a point is
selected, the value changes to reflect the gray level at that point. Knowing this value
makes it easier to determine the best Gray Low and Gray High values to set.
Gray Low
Adjusts the gray low-tolerance value. The lower the value, the more white is
tolerated in the image. The higher the value, the less white is tolerated in the image.
NOTE: Gray Low values are typically lower than Gray High values.
Range: 0–255
Gray High
Adjusts the gray high-tolerance value. The lower the value, the less white is tolerated
in the image. The higher the value, the more white is tolerated in the image.
NOTE: Gray High values are typically higher than Gray Low values.
Range: 0–255
Dilation
Displays how the image appears after the Dilation calculation.
Dilation First
counter
When Dilation First is checked, the counter above the Dilation First checkbox
controls the zoom of the image. When Dilation First is unchecked, the counter
controls how much of the non-gray areas in the image are ignored.
Range: 0–20
Dilation First
checkbox
Sets the order in which the dilation and erosion calculations are performed. If the
Dilation First checkbox is checked, the system performs the dilation calculation first.
If the checkbox is unchecked, the system performs the erosion calculation first.
When Dilation First is unchecked, the Dilation and Erosion labels switch places.
Erosion
The image above Erosion shows how much white is filtered from the image.
Tolerance Sets the tolerance for how similar other mark images can be to the selected image,
allowing the system to eliminate similar marks.
