of a video display 104 preferably straddling the centerline of the display as shown fig5 shows that the limits of viewer position with respect to the display 104 for calculation purposes may be limited to a left position 106 and a right position 108 defining respective maximum viewing angles u00b1 u03b8 as shown when the viewer is located at left limit position 106 the image from the left camera 102 exclusively may be presented on the receiving display not shown whereas when the viewer is located at right limit position 108 the image from the right camera 100 exclusively may be presented on the receiving display thus when the viewer is at either limit position 106 108 no combining of images from the cameras 100 102 is implemented on the other hand when the viewer is located shown by the line 110 between the limit positions 106 108 the below described interpolation is undertaken to alter the disparity map discussed further below with more specificity and now turning to fig6 and 7 as shown in fig6 when the viewer is at position 112 the distance between the limit positions 106 108 is u201c t u201d and the distance between the viewer position 112 and the limit position closest to the viewer in the example shown the left limit position 106 is u201c t u201d 39 with a defining the angle between the perpendicular to the center of the display 104 and the limit position closest to the viewer and a defining the angle between the perpendicular to the center of the display 104 and a line from the viewer position 112 to the center of the display 104 then now with the above relationship.
