DISPLAY - IMAGE PICKUP DEVICE

摘要

PURPOSE:To simplify the configuration of the display image pickup device compatible with a large screen and to realize low cost by making visual lines of talking parties coincident with each other. CONSTITUTION:A screen comprising very small prism arrays 3 compatible with a large screen and manufactured inexpensively is arranged in front of a display device 1 and made inexpensively. The optical axis center of display and the optical axis center of image pickup are made coincident in front of the screen through the refraction of the very small prisms of the very small prism arrays 3 and then the coincidence of visual lines of talking parties is simply realized without changeover of display/image pickup by means of transmission division. Display or image pickup of a double image is prevented by providing a light interruption slit 4 corresponding to the very small prisms.
