  The present invention relates to an image display system for displaying an image using a projector, an image display method, and a screen device for use in the image display system.

  A projector that is a projection-type image display device requires a screen for reproducing a projected image. Classification of screens for displaying projected images of projectors includes hard-type screens that are hard and hard to break, soft-type screens that are convenient for storage and movement, and front projection types based on the projection direction of the projector There is a classification method such as a screen of the rear projection type.

Regardless of which screen is used, the movement of a person or the like is hindered or the viewing direction is limited due to the presence of the screen. For this reason, an image display system combining a projector and a screen is mainly used in a limited place such as a conference room or a movie theater.
On the other hand, recently, there are screens such as “fog screen” and “white smoke screen” (see, for example, Patent Document 1 and Patent Document 2).

  The technique (referred to as the first conventional technique) disclosed in Patent Document 1 forms a screen (fog screen) by generating fog uniformly and planarly, and an image projection apparatus such as a projector is formed on the formed fog screen. The projected image is displayed. According to such a fog screen, movement of a person or the like is not hindered, and a person can enter the screen, place an object, or a person can pass through the screen.

  Therefore, by forming such fog screens in passages such as airports, stations, hospitals, shopping malls, etc., it is possible to function as a guidance display board for displaying directions to the destination and displaying various information. Also, by using it for various events and shows, it can function as a device for obtaining an unprecedented presentation effect, and a new image display system combining a fog screen and a projector can be constructed. .

  The technology disclosed in Patent Document 2 (referred to as the second conventional technology) forms a screen (white smoke screen) by generating white smoke, and an image projection apparatus such as a projector is formed on the formed white smoke screen. The projected image is displayed. Similar to the fog screen, such a white smoke screen can be used in the same way as a fog screen because a person can enter the screen, place an object, and a person can pass through the screen.
