Viewing zones in autostereoscopic imaging systems based on lenticular, parallax barrier and IP plates

In autostereoscopic imaging systems using lenticular, parallax barrier and integral photography plates as the viewing zone forming optics, the quality of the perceived image is different for different part of the viewing zone because of different view image mixing. The image quality is quantified by the number of different view images viewed simultaneously along the viewing axis. The image quality decreases as the viewing distance increases.
