  • Patent number: 6072545
    Abstract: An image rotating apparatus presents a projected video image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the apparatus, can view the projected video image simultaneously. The video image rotating apparatus utilizes light valve technology to create red, green and blue images from an analog composite video signal, and a Phillips prism that aligns the images produced by the light valves for projection through an optical system. The image produced by the light valves is rotated, either mechanically or electronically, in synchronization with rotation of the projection screen.
