ABSTRACT:
An interphone with television includes a terminal device having a wide-angle image input camera, an image output circuit, and a master device for receiving an image signal from the image output circuit. The master device converts the image to a digital format and stores the image signal in an image memory. The image may be panned, magnified, and corrected using digital processing techniques. The contents of the image memory are converted to an analogue signal for reproduction on a monitor.
