1. A predictive head-tracking multiview display, comprising:
a multibeam backlight configured to provide a plurality of light beams having different principal angular directions corresponding to different view directions of a multiview image;
a processor configured to:
receive a plurality of provisional views of the multiview image, the plurality of provisional views corresponding to the different view directions;
receive information about a predicted position of a user, the information about the predicted position based on a plurality of measured positions of the user; and
shift the provisional views with respect to the view directions to form a plurality of shifted views that correspond to the different view directions, the shifted views being shifted by a shift value that varies as a function of the predicted position of the user and varies over a field of view of the multiview image; and
a light valve array configured to modulate light beams of the plurality of light beams to provide the plurality of shifted views of the multiview image to the view directions as the multiview image, the light valve array including a raster scan, the light valve array having a latency that varies across the light valve array as a function of the raster scan, the predicted position comprising a predicted position at a location-dependent future time, the location-dependent future time differing from a reference time by the latency of the light valve array.
