摘要:
A projector system of the present invention includes a projector 10 and a personal computer PC as an information terminal, which communicate with each other via a network connection. The projector 10 generates a password required for establishment of the network connection and projects the password on a screen SC. A user of the personal computer PC inputs the password projected on the screen SC. The password is used for authentication of the network connection between the projector 10 and the personal computer PC and cipher communication therebetween. This arrangement of the present invention enhances the convenience of the projector that is capable of establishing a network connection with the information terminal, while ensuring secrecy of communicating data.

With a conventional image-display system, a presenter sometimes has difficulty in providing every viewer with an easy-to-see picture. When projecting an image transmitted from a computer operated by the presenter and enabling the viewer to watch the image projected by the projector, the projector receives image data transmitted through two-way communication from the computer operated by the presenter, projects an image represented by the received image data and transmits the received image data to a client computer operated by the viewer through the two-way communication, and the client computer receives the image data transmitted through the two-way communication and displays the image represented by the received image data on its display.

There has been a problem of necessitating a complicated work for establishing a connection capable of intercommunication between a computer as server and a projector as client.When a connection is established between a server 20 and projectors 301 through 30n, a communication command is issued according to UDP-based broadcasting to retrieve connectable projectors 301 through 303. Thereafter, the projector 301 to be connected is selected and is assigned an IP address to establish the connection. In this manner, a user can easily obtain a connection environment capable of intercommunication between the server 20 and the projector 301. A TCP/IP communication command is used to input or output image data, ensuring reliable transmission. Since the authentication can be provided using a keyword projected during the connection establishment, it is possible to prevent an unauthorized access to the projector 301 by an outsider.
