Abstract
(EN)
One embodiment of the present invention is a display system comprising: a main display unit (1) which displays an image; a plurality of secondary display units (2-n) which respectively display a plurality of images; a detection unit (17) which detects a number of viewers of the main display unit and a number of viewers of each of the plurality of secondary display units; and, a control unit (16) which, if the number of viewers of the main display unit detected by the detection unit is at least a prescribed value and the numbers of viewers of the secondary display units are less than the prescribed value, switches the images displayed on the secondary display units to the same image as the image displayed on the main display unit, and causes the same to be displayed.
