Solution
LabVIEW
The palette settings on the front panel need to be changed from the default greyscale to binary to view the image.
- Right click on the image display on the front panel.
- Select Palette >> Binary.
Vision Assistant
The image palette needs to be changed to the Binary imaging palette to view the image, as shown in the image below.

Paint or Other Third Party Program
There are two options to view the image in a third party program:
- Change the palette in the third party program, similar to the example shown in Vision Assistant.
- Change the actual pixel values to contain more contrasting values in LabVIEW before opening in the third party program.
- IMAQ Threshold.vi and IMAQ AutoB Threshold 2.vi have an input called Replace Value.
- Wire a value of 255 to the Replace Value input so all pixels with a value of 1 will be replaced with 255 to increase contrast.
