Apparatus and method to display images from projection device mounted in vertical position
First Claim
1. A video projection system, comprising:
- a projector having a lens for projecting a video image in a first direction for viewing on a projection surface; and
an image deflection device having a reflecting device selectively positioned in front of said lens for deflecting the video image into a second direction for viewing on the projection surface, thereby allowing the projector to be mounted in an orientation in which the lens does not face the projection surface, wherein said image deflection device comprises a first threaded component for mating with a second threaded component which is coaxial with the lens of the projector, thereby providing a removable coupling between the image deflection device and the projector.

Abstract
A video projection system has an image deflection device to provide additional mounting options for a projector. The deflection device selectively positions a mirror in front of the projection lens to deflect the video image away from the optical axis of the lens, thereby allowing the projector to be mounted without the lens facing the projection surface. The projector includes an image processor for selectively flipping the video image to accommodate a first mounting configuration in which the projector rests on a horizontal surface with the lens facing the projection surface, a second mounting configuration in which the projector is upside down and attached to a ceiling with the lens facing the projection surface, and a third mounting configuration in which the projector is attached to a vertical surface with the image deflection device mirror positioned in front of the lens to deflect the optical image toward the projection surface.

12. A video projection device, comprising:
-
an image processing engine for correcting image distortion and orientation in a digitized image signal to accommodate different placement options for the video projection device; a light engine comprising a light source and a display device for creating an optical image from the digitized image signal; a projection lens for projecting said optical image in a first direction for viewing on a projection surface; and an image deflection device having a mirror selectively positioned in front of said projection lens for deflecting the optical image into a second direction for viewing on the projection surface, thereby allowing the video projection device to be mounted in an orientation in which the projection lens does not face the projection surface, wherein said image processing engine comprises a means for selectively flipping the optical image horizontally and vertically, and wherein said means for selectively flipping the optical image has a first setting to accommodate a mounting configuration in which the video projection device rests on a horizontal surface with the lens facing the projection surface, a second setting to accommodate a mounting configuration in which the video projection device is upside down and attached to a ceiling with the lens facing the projection surface, and a third setting to accommodate a mounting configuration in which the video projection device is attached to a vertical surface with an optical axis of the lens substantially parallel with the vertical surface and the image deflection device positioned in front of the lens to deflect the optical image toward the projection surface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
