Abstract

To provide a goggle type display device system that can prevent harm to user'"'"'s health. If anomaly is recognized in mind and body of a user, first video signals provided from an external device stop being displayed on LCD panels and, instead, outside scenery taken by CCD image capture elements is displayed. The user may be alarmed by this about anomaly of his or her body and, further, relaxed by looking at the outside scenery presented.
