Patent ID: 7500758

Claim:
A device for image display, comprising: positionable projection optics that are integral with the device body and movable with respect to the device body for projecting an image in different directions with respect to the device body; a projection display for generating an image to be projected by the projection optics; a light source for directing light through the projection display toward the projection optics; a position sensor for detecting the position of the projection optics with respect to the device body; and an image translator for translating image data supplied to the projection display in accordance with a signal from the position sensor indicating the position of the projection optics so that the image displayed on the projection display produces a projected image that is correctly oriented with respect to the device; wherein the positionable projection optics comprise: lens elements that are movable between a first position that points in a direction along a direct optical path from the projection display and at least a second position that points in a direction that is at a 90 degree angle with respect to the pointing direction of the first position; and an electro-optical reflection device that intersects the optical path at approximately a 45 degree angle and that is electrically switchable between a primarily transmissive state and a primarily reflective state that deflects light in the optical path at approximately a 90 degree angle.
