  • Method of calibrating an observer tracking display and observer tracking display
    Patent number: 5777720
    Abstract: A calibration method is provided for an observer tracking display, for instance of the autostereoscopic 3D type, which forms steerable viewing zones and which comprises a tracking system for tracking an observer and a controller for controlling the viewing zones in response to the tracking system. The viewing zones are steered to direct light in a plurality of directions in turn. The observer then moves to the optimum position for viewing the display. The tracking system determines the optimum position for each viewing zone direction and the positions and directions are stored in association with each other so as to form a mapping in the controller for controlling the viewing zones in response to the tracking system during normal use of the display.
