Embodiment
[0095] 1. In a first embodiment, a tracking system is used in combination with a camera and a fixed parallax barrier 3D display. This system is in Figure 5 shown in a. A parallax system (NP6-3stag1) with a repeating staggered pattern of 6 sub-pixels, a slanted barrier with a slope of 1 pixel per row and a slit of 3 pixels wide gives very good tracking performance. Part of this good performance is due to "redundant" sub-pixels that are initially hidden from the user and can be preloaded with view information. As the user moves and these hidden sub-pixels are revealed, the correct view information can be maintained for each eye. The image processing hardware is configured to implement method 1 and / or method 2 as described above.
[0096] 2. In a second embodiment, a tracking system is used in combination with a camera and a switchable parallax barrier. The barrier can be switched in a discrete manner, such as Figure 5 As shown in c, the electrodes are used to control the ...
