<p>PROBLEM TO BE SOLVED: To provide a projection system for automatically adjusting a focus of an optical projector by an evaluation function applied to projection image analysis. SOLUTION: The projection system includes total reflection element, an image reader, an analysis system, and a server. The image reader reads the projection image drawn by the optical projector and the total reflection element, and outputs a read signal. The analysis system analyzes the read image by the evaluation function, determines the clearest image on the projection plane, and outputs a control signal. The server automatically performs the focusing to the optical projector on the basis of the control signal.</p> |
