Webcam configuration

[mreuveni]

I am using an auto focus webcam with my vision system.  I am having an issue that each time i take a picture it opens up a new camera session with random configurations.  I need a specific set up in order to see all the components i am looking for.

The algorithmi have for taking an image is:

        CurrentSession = New NationalInstruments.Vision.Acquisition.Imaqdx.ImaqdxSession(CurrentCamera)
        'get image
        CurrentSession.Acquisition.Configure(Acquisition.Imaqdx.ImaqdxAcquisitionType.SingleShot, 1)
        CurrentSession.Acquisition.Start()
        CurrentImage = CurrentSession.Snap(CurrentImage)

        'Stop, unconfigure, and close camera
        CurrentSession.Acquisition.Stop()
        CurrentSession.Acquisition.Unconfigure()
        CurrentSession.Close()

        CurrentImage.WriteJpegFile(Image_name)

Is there a function that sets up the camera? it is a logitec camera.

Thanks

Is the camera configured correctly the first time you take an image? From the code you provided, it seems like you should be able to take multiple images during the same session and write them to file. Once you are done you can end the session and unconfigure the camera at that point.

What configuration are you trying to get with the camera?

I am actually getting a timed out error quite frequently

Where do you get the time out error? Is there an error code along with it?

During the Snap Function

Have you tried to use the camera from Measurement & Automation Explorer? This would help you know if it is an issue with the camera/driver or the code (because it eliminates the code aspect). Try to access the camera in Measurement & Automation Explorer and use the Snap function from there.

I occasionallyget a timed out error from there too

What is the error code that you get?

Can you provide the entire error text that comes up? A screen shot would be helpful if possible.
