Abstract
An interactive display system that includes an interactive display screen. An illuminator is positioned to illuminate one of the inner or outer surfaces of the display screen. At least two cameras are placed so as to view the illuminated surface of the display screen. Each of at least one of the cameras are positioned such that specular reflections from the illuminator are received by the camera. The images from the different cameras are merged to form a merged image in which specular reflections are reduced or even cancelled.
