Head-tracking multiview display and method

A method of operation for a head-tracking multiview display, the method comprising:

• providing, with a multibeam backlight, a plurality of light beams having different principal angular directions corresponding to different view directions of a multiview image;
• receiving, with a processor, a plurality of provisional views of the multiview image, the plurality of provisional views corresponding to the different view directions;
• receiving, with the processor, information about a tracked position of a user;
• shifting, with the processor, 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 tracked position of the user and varies over a field of view of the multiview image;
• and
• modulating, with a light valve array, 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.

A head-tracking multiview display, comprising:

• a head tracker configured to provide a tracked position of a user with respect to the head-tracking multiview display, the head tracker comprising a camera configured to capture an image of the user, the head tracker further comprising an image processor configured to determine a position of the user within the captured image to provide the tracked position;
• 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;
• 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 tracked 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.
