DISPLAY DEVICE AND DISPLAY METHOD

摘要

Display control that extends a user's visual ability is accomplished. By wearing an eyeglass-type or headgear-type mounting unit, he or she is allowed to see display means disposed in front of his or her eyes. By causing a part of a screen area of the display means to be in a through-state and a display with a display image signal to be executed, the user can see an image of a scene different from a scene that he or she ordinarily sees with a display of the display image signal while he or she can see the ordinary visual scene with the through-state area.
