Abstract

PURPOSE: To hold an efficient and correct conference by superimposing handwritten characters on a still picture or a moving image, and displaying the picture on a self-station and the other station on a real time basis.
CONSTITUTION: A picture signal from a camera 4 is inputted to a picture signal input terminal 12. It is transmitted from a line connecting terminal 13 to the other station and simultaneously it is inputted from a picture signal output terminal 15 to a picture signal input terminal 16 of a superimposing circuit part 3. The signal from a handwritten character input part 6 is inputted from a handwritten character signal output terminal 22 to an input terminal 21, and transmitted from a line connecting terminal 14 to the other station. Simultaneously it is inputted from a handwritten character signal output terminal 18 to an input terminal 17 of the superimposing circuit part 3. Further, the signal video-clamped and addition-amplified by the superimposing circuit part 3 is displayed on a monitor 5. It is displayed on the other station as well in the same way.
