If it's an CALayer (which I'm pretty sure it is, but I'll verify it now), you can do this:

UIGraphicsBeginImageContext();
[yourCameraPreviewLayer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGrahpicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Edit: I presume you're using AVCaptureVideoPreviewLayer, then it is a CALayer, so above should work.
