Abstract
A projector slide has eight possible orientations, only one of which is the correct one to project a properly oriented image. For an automatic orientator to work there must be a simple way to recognize any one of the eight orientations and decide how to place the slide in the correct orientation. A method and device is described here which accomplishes this task.
