Capture properties


resuS

Recommended Posts

Hi, everyone!

I have a camera in my notebook and I want to grab pictures using this. I tryed to use IMAQdx Grab.vi but I was confronted with difficultis: I did'n find how I can change capture properties such as contrast, brightness and so on.

However I've found the suggestion: when I'm changing capture properties in Skype(!!!yeah!!!) this settings are available after in labVIEW. But this is too complex :throwpc:

Anyone knows does labVIEW have a special VI for this case? I can't believe that Skype has and LabView has't!

Thank you for you reply

I've seen this articles, but this seems useless. I read this again, but I'm thinking the same. Where can I get the completed list of attributes? I put into ActiveAttr string identical to string from this manual and got error: -1074360305 attribute not supported by the camera. This is impossible, every camera support brightness. Is Skype more powerfull than LabVIEW?:)

Don't worry about it. It was the provocative joke! :shifty:

Would be better if you answer the question in 4th post in this topic.

I notice a strange thing: Error -107...305 appears then the program is run for the first time since last diagram's changes. Whereas after second or third time everything is good. Could you explain me why is that?

I'm still interested in this problem.
:frusty:
I've solved this with using a trick: create a session twice (see pic.), But it seems too ridiculously.
