PROBLEM TO BE SOLVED: To attain improvements in convenience, mobility, expandability and operability by having a camera control means for controlling the camera of a video telephone set of a communicated party, transmitting a camera control signal to the video telephone set of the communicated party by using the camera control means, receiving an image signal, according to the camera control signal from the video telephone set of the communicated party and displaying it on a display. SOLUTION: A camera control digital signal which a camera control device controller 54 generates is inputted to a camera control interface circuit 53b by with a parallel signal, is converted into serial data, inputted to a data port of a multiple separation control part 52b, multiplexed together with voice and a video signals, and outputted to an ISDN network 57 via a digital communication line control circuit 51. An integrated type video telephone 50a of the other party receives multiplexed signals, separates them into the voice image, and data signals by a multiple separation control part 52a via a control circuit 51a, reproduces the data signals into four parallel signals and performs a condition setting of an external camera 56. |
