1. A stereoscopic display system comprising:
a display apparatus configured to display a three-dimensional (3D) stereoscopic image; and
a control system,
wherein the control system is configured to:
obtain information indicating a predetermined position in a stereoscopic viewing zone, wherein the predetermined position is located at an intersection of a first line and a second line, wherein the first line extends between ends of the stereoscopic viewing zone along a direction parallel to a screen of the display apparatus and the second line extends from ends of the stereoscopic viewing zone along a direction normal to the screen of the display apparatus;
acquire an image captured by an imaging device; and
display the 3D stereoscopic image on the display apparatus based on a position of an observer detected in a predetermined tracking area in the acquired image,
wherein the predetermined tracking area is a part of an area in which the observer is trackable and the predetermined tracking area coincides with the stereoscopic viewing zone in which a stereo image can be recognized from the 3D stereoscopic image,
wherein the control system includes an elapsed time determination module configured to count elapsed time while displaying the 3D stereoscopic image based on a position at which the observer is detected last after the detected observer has become untrackable in the predetermined tracking area,
wherein the control system is configured to display the 3D stereoscopic image suitable for the predetermined position in a case where no observer is detected in the predetermined tracking area until the elapsed time exceeds a predetermined value;
wherein the control system is configured to display the 3D stereoscopic image on the display apparatus based on a position of an observer located closest to the predetermined position among a plurality of observers detected in the predetermined tracking area, and
wherein the control system is configured to maintain a latest 3D stereoscopic image in a case where a plurality of observers located closest to the predetermined position are detected.
