IMAQdx Grab and Save image

[JSwann]

Hello:

I'm trying to grab and save an image collected from a USB webcam at a frequency of apprximately 1 Hz. I would like to be able to adjust this up or down slightly, but does not need to adjust significantly. Some indication of time with the image would be great as well. Any suggestions or starting points would be much appreciated.

Thanks, 

Josh

Have you looked at the Examples that ship with LabVIEW?  I believe there is code there that will do most (if not all) of what you describe.

I have looked at them some but haven't come across one that has helped me completely.

Bob was exactly telling you the starting point that you were expecting.

But if you want a specific location then you can go to example finder and search for example 'Grab' there you can find 'Grab and Attribute Setup.vi' which helps you set the parameters

Of course not!  The NI Developers who create the Examples don't think "What would JSwann want us to do for him/her?", they think "How can we illustrate a Snap and Save sequence", depending on users having sufficient initiative and understanding of LabVIEW to figure out (a) how to turn a "Do it Once" example into a "Do it Once per Second", (b) how to incorporate user-specific information (such as Date, Time, Sequence Number, etc.) into a File Name, (c) how to handle timing issues to change from "Once per Second" to "at a frequency of F", etc.

You will either have to do a little work, yourself, or hire someone to do it for you.  Please don't ask us to work for you for free.

To add on to what Bob (tells it like it is) Schor said, I spent 2 minutes on google and found another thread asking how to save pictures at a certain rate. I think one of the humps to getting into LabVIEW is to stop viewing it like an Ikea furniture set. All the parts are not always going to be there for you (and hopefully your software will not break after 2 years). You have to view it like a machine shop, and sometimes get your hands dirty to make a part that fits well for you.
