Distorted Camera Output

[Butterworth]

Hello there. I will work on a project  about Real-Time Vision via Labview. When I've tried to test my cam at NI MAX(nimaxscreenshot.jpg) everything is okay. But when I try to test my cam via simple test vi(blockdiagram.jpg) my cam output(frontpanel.jpg) is distorted. My camera is Basler Pylon acA2500-14gc. What is the problem?

have you tried without vision express by using imaqdx functions only?

Actually I am new to image processing at Labview so I don't have knowledge about this toolkit. The blockdiagram that I used is from a Youtube video. Now I used this blockdiagram(block2) and result is same distorted output.

I have seen something like this when the image size is maxed out on the camera.  Try reducing the acquisition area by a few pixels in each dimension.  If this fixes it, you can slowly add pixels until you figure out the exact problem.  Make sure your starting pixel is even, or your bayer correction will be wrong.

How can I do this in Labview?

The easiest way is to do it in MAX, then check it in LabVIEW.  You can set camera properties from LabVIEW, but it is more work.

Hello Mr. Ammons, in MAX, which option do I need to reduce the acquisiton area you've talked about? I could not find an option about change acquisition area.

In your MAX screenshot it is the region of interest.

But when I try to change it, it turns into its original value(Resolution values).
