PROBLEM TO BE SOLVED: To provide an intercom system in which zooming display and scroll control of a video image captured by a camera of an entrance slave unit is performed by an automatic operation.SOLUTION: When a visitor presses a call button in the entrance slave unit, a CPU of a habitable room master unit confirms a calling signal, makes a speaker generate ringing tones, then processes a video image of a wide angle camera received from the entrance slave unit, performs the zooming display of a motion picture on a monitor of the habitable room master unit, and automatically scrolls zooming display screens Z1-Z5 in predetermined patterns. When the scroll patterns are circulated once, the CPU of the master unit stops the automatic scroll and switches the display on a monitor 31 from the zooming display screen to a wide display screen W. Otherwise, when a resident touches a touch panel of the monitor, scrolling is stooped and then zooming display of a range including a touched part is continued.SELECTED DRAWING: Figure 4 |
