Color Area Menu - Banner iVu Plus TG Series Instruction Manual

Color Tolerance
Main Menu > Inspection > Sensors > ColorCmp > Color Tolerance
Use Color Tolerance to adjust the maximum acceptable difference (in %) between the taught color and the color detected in
the live image.
The live value drawn inside the slider indicates the color difference for the current image. Move the slider to the right to
increase the maximum acceptable difference.
Intensity Tolerance
Main Menu > Inspection > Sensors > ColorCmp > Intensity Tolerance
Intensity Tolerance defines the grayscale brightness level necessary to constitute a match. This value ranges from 0 to 255.
As the Intensity Tolerance value is changed, the acceptable minimum and maximum limits on either side of the Reference
are calculated. When this tolerance is set to 0, only the taught intensity of each color is acceptable; that is, no change in
intensity is allowed. Or, to say it another way, the intensity of illumination for a given color target cannot change.

9.1.7 Color Area Menu

Available on iVu Color models only.
Main Menu > Inspection > Sensors > ColorArea
Use a Color Area sensor to separate same color blobs, or Binary Large Objects, from the larger scene and to analyze parts
with color variations that cannot accurately be detected by gray scale sensors. Use an Color Area sensor to ensure that a
specific color feature, or multiple features, are present on a part. If there is more than one of the identified features on a
part, the number expected can be set as well. During the inspection, the sensor verifies that each part or package includes
the correct color and specified number of features.
Example applications include:
• Verify a fuse and its color, such as dark blue or light blue
• Check how many red parts are present
• Verify the color and correct number of objects in a case
To configure as a Color Area sensor, set the following parameters:
• ROI and Mask
• Color Select
• Area Range
• Pass Count
• Pass Total Area
• Tolerance
ROI and Mask
Main Menu > Inspection > Sensors > [Sensor Type] > ROI and Mask
Sensor Type in the menu path above refers to the sensor you are configuring or updating.
Note:
The Region of Interest (ROI) is the user-defined area on the screen that the sensor analyzes. The ROI type can be
rectangular, elliptical, or circular. From the drop-down list, select the ROI type to use for the inspection. Adjust the ROI as
appropriate for the inspection. An ROI can be as large as the entire Field of View (FOV).
Select the Enable Mask checkbox to allow mask ROIs to be used with the inspection ROI.
