Like the question here, I am trying to capture images with Emgu. But even when running the examples I get a black image. I have tried changing the new Capture() to new Capture(1) all the way through 12… With no change.

I am using a Mac-book Pro 15″ (early 2011) running Windows 7 x64 Ultimate.

Note: The Green light next to the camera turns green when the program ‘starts to capture’ – The camera works in other applications so I don’t think that it’s the camera/configuration that’s the problem…

    This is likely an issue with OpenCV not supporting the particular driver that Windows selected for your iSight camera. According to this list OpenCV supports the iSight camera, but only on Linux and Mac OSX.

    You should check out this related SO post. You may have some luck trying to use an external capture library like Touchless. Here is a little tutorial on CodeProject about it.

    Hope that helps!
