IMAQ USB CAMERA BLINKING

[Alex_Pitta]

I'm trying to do a real time inspection with Vision Assistant 8.6 and when I start capturing with IMAQ USB GRAB inside Labview 8.6 the video starts blinking and I can't see for sure what is happening.

Is there any solution to stop it and make the image smooth without blinking?

There is an image below showing the block diagram.I'd appreciate if someone could help me.

What is there in other cases? A similar grab?

Hi, Alex,

You have clear race conditions between Grabbing/Processing/Visualization.

Try to copy image to other buffer, then "blinking" should goes away.

Something like that:

 

Also remember, that at first grab iteration your image is not valid, because grab occurred after processing.

Thanks for answering, but it is still not working.

The image keeps blinking of the same way. Do you have any other idea?

Sincerely,

Alex
