Hi,
I am getting images from a camera with 90 fps. I need to evaluate all of them, but only want to display every 10th picture.
I posted an Image with my attempt.
The trouble I have is, that the Overlay on the picture is not beeing shown on the Frontpanel. However according to the "Sonde" (sorry, german version) the Overlay should be there.
If I have every picture shown, the Overlay is flickering.
Thanks for your help!

You have kind of race condition in your VI (images transferred by reference, not by value).
Add IMAQ Copy before display. In some cases calling Refresh Image method may be also useful.

Hi,
Thanks for your help!
That did the trick!
Still I wonder, as my application will be time-critical, howmuch slower that change makes my program?
But I reckon that those racing-conditions would ruin my evaluation anyway, so I will have to accept it anyways...
Thanks a lot!
