I have some trouble with the Camera not being quite ready when I grab an Image from it. It sometimes takes 2-3 seconds before it returns a real image. I have a work-around which is to grab an image, test if it's all black, if so, wait 1 second and try again until it's a real image. Is this the best way to go about checking if the camera is really ready, or am I missing something built in?

very strange it usually does not take so long, what is the configuration of your hardware, and what the configuration of the camera?
