A video image rotating apparatus includes a rear projection screen rotatably
disposed
in a generally horizontal plane, thus allowing only a single mirror to be angularly
positioned over the screen to project video images to viewers. An optical system
is positioned below the screen and vertically aligned therewith for projecting
video images onto the screen. Preferably, the video images are mechanically rotated
by rotating a portion of the optical system at a rate of rotation that is one-half
that of the screen so that all viewers surrounding the video image rotating apparatus
will see the same picture substantially simultaneously and continuously. Alternatively,
the video images produced by the optical system may be rotated by an electronic
image rotation system that electronically rotates the images produced in synchronization
with rotation of the screen.
