resuS Posted August 17, 2011 Report Share Posted August 17, 2011 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 Anyone knows does labVIEW have a special VI for this case? I can't believe that Skype has and LabView has't! Quote Link to comment
asbo Posted August 17, 2011 Report Share Posted August 17, 2011 This article on getting and setting IMAQdx attributes may get you going in the right direction. Quote Link to comment
resuS Posted August 18, 2011 Author Report Share Posted August 18, 2011 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? Quote Link to comment
resuS Posted August 18, 2011 Author Report Share Posted August 18, 2011 I notice 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? Camera attributes.vi Quote Link to comment
resuS Posted August 18, 2011 Author Report Share Posted August 18, 2011 I'm thinking I solve the problem. Vi is attached. This VI is scaled-down version of CameraSetting in Skype:) P.S. Strange thing is described upper is still unexplained... In my Vi start and end acquisition twice becouse this is. Camera settings.vi Quote Link to comment
crelf Posted August 18, 2011 Report Share Posted August 18, 2011 Is Skype more powerfull than LabVIEW? No, skype is not more powerful than LabVIEW - skype is a video calling application, LabVIEW is a programming language. There can be no comparison. Quote Link to comment
resuS Posted August 19, 2011 Author Report Share Posted August 19, 2011 Don't worry about it. It was the provocative joke! 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. I've solved this with using a trick: create a session twice (see pic.), But it seems too ridiculously. Quote Link to comment
