Teleconference system with image display and input means
First Claim
1. A conference system comprising a plurality of individual terminals which are provided with individual image input means and individual image display means respectively and connected to each other via communication lines, whereinsaid image input means of said individual terminals is provided with a transparent image input surface composed of a pressure sensitive transparent tablet for inputting an image drawn thereon;
- said image display means of each of said individual terminals, whereupon said image input surface of said image input means is superimposed, is provided with an image display screen whose image display position corresponds to the input position of said image input surface by equivalent scale;
said system further comprising a central processing unit which is connected with said individual terminals via a data transmission line and receives image data inputted by said image input means of said individual terminals and transmits said image data to said image display means of other individual terminals; and
a large display unit which is connected with said central processing unit and which displays said image data transmitted from said individual terminals to show said image data to all attendants of said conference.

Abstract
The invention provides a novel teleconference system which saves space being occupied by individual terminal equipment by superimposing a transparent image input surface of an image input device over a display screen of an image display device, and is provided with a central processing unit which causes the images being received by image input device of an individual terminal equipment to be displayed by image display devices of other individual terminal equipment, furthermore, allows operators to easily correct and add images shown on a display screen by making an input position of an image input surface coincide to a display position of an image display screen.
