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.

Claims

1. A goggle type display system comprising:

two display devices;

first video signals being inputted from an external video signal supplying device;

two image capture elements for converting outside images into second video signals;

a sensor for converting vital information of a user into a vital information signal; and

a video signal control circuit for providing the two display devices with video signals,

wherein the video signal control circuit provides the two display devices with the first video signals or the second video signals on the basis of an index being obtained by numerically processing the vital information signal.
