Abstract
The image transmission device for high resolution color still images, GT-1000 (Image Talk) has been developed. It uses the ITU-T recommendat ion T.81 (JPEG) as a image coding method and the TTC standard JJ-41.10 as communications protocol. A high resolution color still image (768 x 480 pixels) can be transmitted over an ISDN line in 6 seconds by usi ng newly developed LSIs: one single chip CODEC and three gate arrays. The system realizes a low price desktop teleconference system by utili zing a twin lens camera that can capture an image up to the size of A3 paper and both a FDD and a HDD for image filing.
