Abstract
In movie house or similar installation for projecting still or moving normal visible images on a screen, a laser device is used to project an infrared spoiling image simultaneously with the normal visible image. When a camcorder is used to record the screen to make illegal copies of the normal visible images, the light sensitive elements of the camcorder convert the invisible spoiling image into a corresponding normal visible image thereby spoiling it.
