PROBLEM TO BE SOLVED: To eliminate a trouble caused by a hard-to-watch image such as a double image in view, displaying a three-dimensional (3D) video when the wearing of spectacles is judged by a communication means and displaying a 2D video when no wearing of spectacles is judged. SOLUTION: The ON/OFF state of a switch 34 attached to spectacles 33 is supplied from the switch 34 to a monitor 31 by a cable 32. Namely, it is supplied from the ON/OFF state of the switch 34 through the cable 32 to the monitor 31 whether a viewer wears the spectacles 33 or not. According to this ON/OFF state of the switch 34, the 2D video/3D video to be displayed on the monitor 31 is switched. Therefore, only when the viewer wears the spectacles 33, the 3D video is displayed on the monitor 31 and when the viewer does not wear the spectacles 33, the 2D video can be displayed so that a hard-to- watch image can be prevented from being displayed on the monitor 31. |
