Patent ID: 7658498

Claim:
A projector for presenting an output image on a display surface, the projector having a projector orientation, the projector comprising: a graphics system operable to format the output image for presentation at a display surface, the output image having an image orientation; a projector orientation sensor operable to detect the projector orientation as an upright orientation or an inverted orientation relative to a vertical axis; and a projector orientation module interfaced with the graphics system and the projector orientation sensor, the projector orientation module operable to automatically adjust the image orientation according to the projector orientation sensed by the projector orientation sensor to present the image upright relative to the vertical axis; and a projector support operable to couple to the projector at one or more attachment points, each attachment point associated with a projector orientation and wherein the projector orientation sensor comprises a sensor operable to detect coupling of projector support at the one or more attachment points, the projector orientation sensor determining the projector orientation from the projector orientation associated with an attachment point coupled to the projector.
