INFORMATION DISPLAY DEVICE

摘要

When display of an image that is sent from a portable terminal (101) for a portable screen is divided into screens for two vehicle mounted terminals, an image receiving unit A (21) of a vehicle mounted terminal A (102) receives image data necessary for screen display on both the vehicle mounted terminals from the portable terminal (101) and stores image data necessary for a vehicle mounted terminal B (103) in a buffer memory unit (23). Thereafter, a cut-out processing unit (25) cuts out the image data for the display screen of the vehicle mounted terminal A (102) and stores the same in the buffer memory (23). Furthermore, an image transmission unit A (26) provides image data necessary for screen display by the vehicle mounted terminal B (103) when required by the vehicle mounted terminal B (103).
