  • Publication number: 20210120227
    Abstract: A control system is configured to acquire an image captured by an imaging device, and display a stereoscopic image on a display apparatus based on a position of an observer detected in a predetermined tracking area in the acquired image. The tracking area is a part of an area in which an observer is trackable and the tracking area includes a stereoscopic viewing zone in which a stereo image can be recognized from the stereoscopic image. The control system is further configured to display a stereoscopic image for a predetermined time based on a position at which the observer is detected last after the detected observer has become untrackable in the tracking area, and display a stereoscopic image suitable for a predetermined position in the stereoscopic viewing zone in a case where no observer is detected in the tracking area over the predetermined time.
