A television conference system having at least one of the functions of automatically directing a camera toward a speaker, of transmitting video signals of picture images from a plurality of television cameras, and of displaying a document image. The television conference system includes a microphone input judgement unit for judging the existence of any input into microphones provided for the speakers of a television conference; a judgement result holding unit for holding the results of the judgement of existence of the microphone inputs over a first predetermined period, the first predetermined period being longer than the shortest period of continuous speaking; a time totaling unit for obtaining the total time of the microphone inputs during the first predetermined period from the results of judgement held in the judgement result holding unit; a speaker specifying unit for specifying as the current speaker the speaker using a microphone having a total time obtained by the time totaling unit which is over a second predetermined period, the second predetermined period being the standard continuing period of noise; and a camera drive unit for driving a camera within a shooting range of the speaker specified as the current speaker by the speaker specifying unit.

Television conference system

An electronic conference system for a remote conference among a plurality of stations, each of the stations comprising an absolute number providing element, for assigning absolute number to an input picture data, an absolute number transmission element for transmitting the absolute number to another station, and a picture data transmitting element for transmitting the picture data only when the other station does not store the number equal to the absolute number, whereby, the same picture data are supervised or coordinated by the same absolute number.

Electronic conference system

A color information input system in which handwritten information, such as letters or figures, etc., is input on an entry area by being converted into electrical signals. In order to display the handwritten information in color, different colored pens are stocked in pen stockers, each pen stocker having a detector which outputs a detection signal when the pen is removed from the corresponding pen stocker. The pen being used on the entry area is detected when it is removed from its pen stocker and color information is generated from the detection signal and passed on to a display unit.
