First Claim
1. A method of controlling a projector that displays an image based on image data, the method comprising the steps of:
- storing a first password in a memory in the projector;
receiving via a controller of the projector a second password sent from a computer;
determining via the controller of the projector whether the second password sent from the computer matches the first password;
transmitting via the controller of the projector the image data from the projector to the computer when it is determined that the second password sent from the computer matches the first password;
receiving delivery permission data via the controller of the projector;
determining via the controller of the projector whether the delivery permission data indicates that delivery of the image data is permissible; and
when the delivery permission data indicates that delivery of the image data is permissible, the controller of the projector visibly projects a password image of the first password combined with the image of the image data.

Abstract
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.

5. A projector that displays an image based on image data, the projector comprising:
-
a memory that stores a first password; and a controller that is programmed to; receive a second password sent from a computer; determine whether the second password sent from the computer matches the first password; transmit the image data from the projector to the computer when it is determined that the second password sent from the computer matches the first password; receive delivery permission data; determine whether the delivery permission data indicates that delivery of the image data is permissible; and when the delivery permission data indicates that delivery of the image data is permissible, the controller visibly projects a password image of the first password combined with the image of the image data. - View Dependent Claims (6, 7, 8)
