PURPOSE:To obtain high-quality images on a large screen provided with a sight-line matching function by arranging a sight-line matching unit at one part of a projective screen and making the level of signals to be projected on that screen equal to the video level of the projective screen. CONSTITUTION:A projective screen 1 is mutually connected through a communication path 5 to a device for projecting images on a compound screen 3 arranging a sight-line matching unit 2 provided with a camera at one part by a video projector 4. Then, video projected by the camera of one sight-line unit 2 is inputted to another display circuit 6 and inputted to the display parts of the other video projector 4 and sight-line matching unit 2. At such a time, among the images projected by the video projector 4, the images to be displayed on the sight-line matching unit 2 are set to the video level equal to that of the surrounding projective screen by a display control circuit 6. Thus, communicating parties A and B can be faced to high-quality opposite side images in the state of matching sight-line each other. |
