IMAQ usb camera->black screen

[hlod]

No, I try to change "name of the image in the "IMAQ Create" vi" also try all "image type in imaq", but still "black screen", also try to add 5-10ms delay; Strange is this that is working in "inbuilt" camera which I have on notebook, but not working on my quickcam logitech, but "grab" is working fine . Any other suggestion?

Thanks again to all who helped me...

If so, why can't you use grab itself.

Because I need picture(snapshot),not streaming "video"!

It's actually working ; Now trying to play with delay, it's working on low 0,3s; this is minimum for normal "snap" 🙂

thanks again

Why I cannot create "case" strocture; I need while loop, and try to implement like button, when I like to take "snapshot"; But it's nothing happend, no matter what I try(try several option)..

Try WebCam Monitor.   It should let your preview and grab images from your Imaq camera - http://www.deskshare.com/wcm.aspx

I dont need additional software, for these reason I have Vision module. I just want to implement wit press button.

You should put the button inside the while loop. Otherwise you read it only once.

Best regards 🙂

Well, yes,yes; but after that(which I already try); it's "snaping" picture while switch is on; I want this just once a after pressed button... i try with shift registor on while loop and "and" but it's not working 😞
