First Claim
Patent Images
1. An observer tracking autostereoscopic display comprising;
- at least three image display devices arranged to direct respective images along respective different directions,an observer tracker for determining a position of at least one observer, andan image controller for dividing the images displayed by each of the image display devices,wherein the image controller is responsive to the observer tracker such that first regions of each of the image display devices which emit light towards a left eye of the at least one observer display left eye view data and second regions of each of the image display devices which emit light towards a right eye of the observer display right eye view data.

Abstract
An observer tracking display is provided in which the image data displayed by at least three display devices along respective different directions is divided depending on the position of an observer. Each eye of the observer can see only some regions of the display devices. The positions and sizes of those regions are calculated for the position of the observer and the display devices are then controlled such that the observer'"'"'s left eye only receives left view data and the observer'"'"'s right eye only receives right eye view data.

16. A method of tracking an observer with an autostereoscopic display of the type comprising at least three image display devices which direct respective images along respective different directions, comprising steps of
tracking a position of at least one of observers, and dividing the image displayed by each of the at least three image display devices such that first regions of the image display devices which emit light towards a left eye of the at least one of the observers display left eye view data and second regions of the image display devices which emit light towards a right eye of the at least one of observers display right eye view data.

17. An observer tracking autostereoscopic display comprising:
-
at least a first image display device, a second image display device, and a third image display device, wherein the first, second and third image display devices are operatively configured such that the first image display device displays a first image to a first range of directions, the second image display device displays a second image to a second range of directions, and the third image display device displays a third image to a third range of directions; an observer tracker for determining a position of an observer relative to the autostereoscopic display; and an image controller which divides each of the first, second and third images into at least one left eye image data region containing left eye view data and at least one right eye image data region containing right eye view data, the image controller varying a composite content of the at least one left eye image data region and the at least one right eye image data region in at least one of the first, second and third images as a function of observer position information provided by the observer tracker, such that as the position of the observer varies the respective left eye image data regions and the right eye image data regions of the first, second, and third images as distributed and displayed among the first, second and third image display devices combine to direct the left eye view data included among the first, second and third images towards the left eye of the observer and the right eye view data included among the first, second and third images towards the right eye of the observer. - View Dependent Claims (18, 19)
