When I opened your image in Vision Assistant the image looked pretty clear with a bit of noise in it. If that is the noise that your talking about, this may be caused by low light levels and the camera's auto gain control.
If the problem is you can't see the picture clearly when opening it in Photoshop or some other Photo utility, then the problem has to do with the way we store 16 bit PNG images. To get around this you could set the 1409 to 8-bit mode if you don't need more than that. The following KB will give you more information on this known issue.
Why Does My 16-bit PNG Image Saved Using IMAQ Vision Appear Black in Photoshop or Photo Editor?
