Patent ID: 7489331

Claim:
An autostereoscopic imaging apparatus for an observer comprising: an eye tracking mechanism for determining a position of each eye of the observer; a computer for constructing a right image and a left image of a scene, the left image being seen by the observer's left eye and the right image being seen by the observer's right eye when looking at the scene from the observer's location; an image display on which the left image and the right image is displayed, the display in communication with the computer; and a lenticular lenslet array sheet through which a first portion of the scene displayed on the display passes and forms a first seamless image of the left image which is visible only to the observer's left eye, and through which a second portion of the scene displayed on the display passes through and forms a second seamless image of the right image which is visible only to the observer's right eye, each lenslet having a pitch which is wide enough so that many pixels of the image on the display are seen magnified through the lenslet by the observer, wherein the observer whose eyes are actively tracked by the tracking mechanism can move around freely in a horizontal direction and a perpendicular direction relative to the display and see a seamless continuous image which is responsive to the movement of the observer relative to the display.
