PROBLEM TO BE SOLVED: To perform projections as if a speaker speaks to a party on a projection display device for video conference and to prevent an incorporated camera from disturbing image display. SOLUTION: A camera 5 photographs the speaker in the front through a small hole 4a on a screen. Therefore, in the case of video telephone or video conference, the speaker is projected on the display device on the side of the party as if he speaks to the party. Besides, since such a camera 5 is located in an area (the part of slanting lines in a figure) where video light does not pass, image display is not disturbed either. |
