PROBLEM TO BE SOLVED: To obtain the image transmitter, the image display device and the image transmission system used for a conference at plural points apart from each other using a high definition image by transferring plural image data externally and a command signal to display at least one of plural image data is outputted externally. SOLUTION: An image transmitter 1109 sends/receives NTSC and High Vision(HV) image data with other image transmitter via a network line 2 and transmission control units 111, 112. A CPU 12 stores an HV image received by an HDTV camera 17 and an HV image received by a transmission control unit 112 to a storage device 15 before a conference, the HV image received by the HDTV camera 17 is sent to the other image transmitter for conference and stored and a command signal to display the stored HV image is outputted. Thus, the image transmitter, the image display device and the image transmission system used for a conference at plural points apart from each other using a high definition image are obtained. |
