DISPLAY SYSTEM, CONTROL DEVICE, DISPLAY METHOD, AND PROGRAM

摘要

A display system includes: display terminals (1-1 to 1-4) which display an image; a display control device (3) which controls display of the image on the display terminals (1-1 to 1-4); and optical shutters (2-1 to 2-4) which are arranged to correspond to the respective display terminals (1-1 to 1-4) and switched between the state for transmitting the incident light while a secret image is displayed on the corresponding terminal and the state for cutting off the incident light while no secret image is displayed.  The display control device (3) controls the display terminals (1-1 to 1-4) so that a secret image is not displayed simultaneously on the display terminals (1-1 to 1-4).
