In response to a requirement of transferring a file from a personal computer PC to a projector 10 that is output by dragging and dropping a corresponding file icon onto a projector icon, a CPU 50 requires setting of a password. The CPU 50 maps the preset password to a file and transfers the file with the password to an external storage device of the projector 10. The projector 10 requires input of a password, which is expected to be assigned to the file, and allows reproduction of the file when the input password is coincident with the preset password.

The invention claimed is: 1. A method implemented by a projector that projects images, the method comprising: (a) in response to a request to provide a working status of the projector, the request received from a client over a network, sending working status information representing the working status to the client over the network; and (b) in response to control information received from the client over the network in response to the sent working status information, controlling the working status of the projector based on the control information, wherein the working status information is sent to the client with screen information from which the client can display a user interface that includes the working status information. 2. The method according to claim 1, wherein the screen information allows for the working status information displayed in the user interface to be changed. 3. The method according to claim 1, wherein the working status information includes information about at least one display characteristic of the image projected by the projector. 4. The method according to claim 3, wherein the display characteristic includes a brightness level of the projected image. 5. The method according to claim 4, wherein the display characteristic includes a contrast level of the projected image. 6. The method according to claim 3, wherein the display characteristic includes a contrast level of the projected image. 7. The method according to claim 1, further comprising: (c) after step (b), sending new working status information representing a new working status of the projector so as to update the working status information sent to the client over the network. 8. A method implemented by a projector that is capable of communicating with a network, the projector including a projection display module, the method comprising: (a) distributing screen information to a client over the network, the screen information including working status information representing a working status of the projection display module, the screen information being distributed to the client in response to a request received from the client over the network; and (b) in response to control information received from the client over the network in response to the distributed screen information, supplying a control signal that controls the working status of the projection display module to the projection display module. 9. The method according to claim 8, further comprising: (c) sending new working status information representing a new working status of the projection display module controlled by the control signal so as to update the screen information distributed to the client over the network. 10. The method according to claim 8, wherein a screen displayed by the client based on the screen information includes a selection element operated to change the working status of the projection display module, actuation of the selection element causing the control information to be transmitted to the projector over the network. 11. The method according to claim 8, wherein the screen information enables the client to display a user interface that includes the working status information. 12. The method according to claim 11, wherein the screen information allows for the working status information displayed in the user interface to be changed. 13. The method according to claim 8, wherein the working status information includes information about at least one display characteristic of the image projected by the projection display module. 14. The method according to claim 13, wherein the display characteristic includes a brightness level of the projected image. 15. The method according to claim 14, wherein the display characteristic includes a contrast level of the projected image. 16. The method according to claim 13, wherein the display characteristic includes a contrast level of the projected image. 17. A method implemented by a projector that is capable of communication with a network, the projector including a projection display module, the method comprising: (a) distributing screen information to a client over the network, the screen information including working status information representing a working status of the projection display module, the screen information being distributed to the client in response to a request received from the client over the network, the screen information enabling the client to generate a user interface that includes the working status information; (b) receiving control information from the client over the network, the control information having been input by the client with the user interface; and (c) supplying a control signal that controls the working status of the projection display module to the projection display module, the control signal being generated based on the received control information. 18. The method according to claim 17, further comprising: (d) sending new working status information representing a new working status of the projection display module controlled by the control signal so as to update the screen information distributed to the client over the network. 19. The method according to claim 17, wherein the user interface includes a selection element operated by the client to change the working status of the projection display module, actuation of the selection element causing the control information to be transmitted to the projector over the network. 20. The method according to claim 17, wherein the screen information allows for the working status information displayed in the user interface to be changed. 21. The method according to claim 17, wherein the working status information includes information about at least one display characteristic of the image projected by the projection display module. 22. The method according to claim 21, wherein the display characteristic includes a brightness level of the projected image. 23. The method according to claim 22, wherein the display characteristic includes a contrast level of the projected image. 24. The method according to claim 21, wherein the display characteristic includes a contrast level of the projected image. 25. A method implemented by a projector that projects images, the projector including a web server module in the projector, the method comprising: (a) in response to a request to provide a working status of the projector, the request received from a client over a network, sending working status information representing the working status to the client from the web server module over the network; and (b) in response to control information received from the client over the network in response to the sent working status information, controlling the working status of the projector based on the control information. 26. The method according to claim 25, wherein the working status information is sent to the client from the web server module over the network with web page information from which the client can display a user interface that includes the working status information. 27. The method according to claim 26, wherein the screen information allows for the working status information displayed in the user interface to be changed. 28. The method according to claim 25, wherein the working status information includes information about at least one display characteristic of the image projected by the projector. 29. The method according to claim 28, wherein the display characteristic includes a brightness level of the projected image. 30. The method according to claim 29, wherein the display characteristic includes a contrast level of the projected image. 31. The method according to claim 28, wherein the display characteristic includes a contrast level of the projected image. 32. The method according to claim 25, further comprising: (c) after step (b), sending new working status information representing a new working status of the projector to the client from the web server module over the network so as to update the working status information sent to the client from the web server module over the network.
