How to avoid image flicker when I am using IMAQ Grab functions

[Cheng]

Hi :
I am using a the IMAQ Grab function to continue capturing images. My display window allow scrolling bar because the image size is huge. However the feature of scrolling bar will cause severe image flicker problem. Is there any approach to avoid flicker ?

This is a known problem with previous versions of the vision software. The issue has been fixed in the most recent version. I would strongly recommend upgrading to the most recent version - if not to fix your problem then for the functionality.

Maybe try using the Low Level acquisition.
It seems a lot faster.

I got 22 fps vs 11 fps with grab setup and grab acquire.
Have a look at the example provided.
