We have recently purchased a Sun VideoPix frame grabber for use on-board a mobile robot. Unfortunately, I am having some trouble with the board... My problem is this: I have two cameras connected to VideoPix, and I'd like to alternately grab images from each as fast as possible. However, there seems to be no good (that is, obvious) way of determining when the board is in sync with the video signal. So, if I switch to a camera and grab an image, more than likely it is garbled. The best solution that I have found thus far is to just delay for an arbitrary amount of time between switching inputs and grabbing the image. I talked with Sun's technical support, and the gentleman that I spoke with seemed to know no more about the board than I did. If anyone has any experience with this aspect of the VideoPix board, I'd appreciate your input. Please email, if possible. Thanks, Jon Courtney
