  2. How to tell different colored objects apart in vision center

  3. My camera image is fuzzy and out of focus.
    The camera is probably out of focus.You can refocus the lego camera by turning the white piece on the camera that the lens is attached to, just as you would to focus an SLR or similar manually-focused camera.

  7. When I use the LEGO camera, I have shadows across my images. What can I do to get rid of these?
    If you have a lot of dark spots in your image then it is a good idea to build some sort of enclosed structure for your light.  This is so that it will be isolated from extraneous light.Here is a picture of several Lego bricks with very bad shadows:These are two pictures of the light box I built...

  8. Why is there a blank picture when I click on define sensor in vision center?
