example, in the display below, the image is marinal for both translational content and for rotational content.
Results
Results indicate the following:
• Number of patterns found: The total number of patterns above the minimum acceptance level and below the
maximum number of patterns.
• Location of the first match: The position of the pattern's center. The origin (0,0) is the upper-left corner of the

7.4 Vision Color Tools
Color tools include Average Color, Color Blob, and Color Match, where color is a discriminator between a good and
bad condition.
7.4.1 Average Color Tool
The Average Color Tool can be used to visually inspect a part by analyzing all colors in a Region of Interest (ROI)
and reducing them to a single set of color values, the average of the combined colors in the ROI.
Usage
The Average Color tool is used to analyze parts with subtle color variations that cannot accurately be detected by gray
scale sensors. This is especially true when the parts are of similar colors.
In combination with a Test Tool, Average Color can be used to sort and verify parts by the presence or absence of a
specified color.
With the use of a Communication Tool, Average Color can be used to measure colors and report what is seen.
• Differentiating yellow as opposed to gray caps on bottles of soda.
• Sorting between dark blue and light blue toys on an assembly line.
