<p>PROBLEM TO BE SOLVED: To provide a presentation system having established safety, suppressed hand-shake, a variety of complicated point configurations and applicability to a multi-screen. SOLUTION: When imaging means 30 images the elements of a random number pattern projected on a screen 10, a computing part 24 specifies elements to be stored in the field of view of the imaging means 30 and reads the coordinates of these elements out of a memory. Then, the computing part 24 calculates the gravity center of the coordinates of the elements and a processing part 2 composes a predetermined point image at the coordinate of the gravity center on the image. Generated image data is output to a liquid crystal projector 1 and the liquid crystal projector 1 projects on the screen 10 an image formed with the point image composed on an image displayed on a CRT of a personal computer 4.</p> |
