Abstract

A projector that projects images includes a projection display module by which the projector projects the images, a network interface by which the projector can communicate with a network, and a web server module coupled to the network interface and to the projection display module. The web server module, in response to a request to provide a working status of the projection display module received through the network interface from a client over the network, sends working status information representing the working status through the network interface to the client over the network. The web server module also, in response to control information received through the network interface from the client over the network in response to the sent working status information, controls the working status by sending a control signal to the projection display module based on the control information.

Claims

1. A projector that projects images, the projector comprising:

a projection display module by which the projector projects the images;

a network interface by which the projector can communicate with a network; and

a web server module coupled to the network interface and to the projection display module, the web server module (i) in response to a request to provide a working status of the projection display module received through the network interface from a client over the network, sending working status information representing the working status through the network interface to the client over the network, and (ii) in response to control information received through the network interface from the client over the network in response to the sent working status information, controlling the working status by sending a control signal to the projection display module based on the control information.

2. The projector according to claim 1, wherein the web server module sends the working status information to the client with web page information from which the client can display a user interface that includes the working status information.

3. The projector according to claim 2, wherein the web page information allows for the working status information displayed in the user interface to be changed.

4. The projector according to claim 1, wherein the working status information includes information about at least one display characteristic of the image projected by the projection display module.

5. The projector according to claim 4, wherein the display characteristic includes a brightness level of the projected image.

6. The projector according to claim 5, wherein the display characteristic includes a contrast level of the projected image.

7. The projector according to claim 4, wherein the display characteristic includes a contrast level of the projected image.

8. The projector according to claim 1, wherein the web server module, after sending the control signal, sends new working status information representing a new working status of the projection display module so as to update the working status information sent through the network interface to the client over the network.

9. A projector that projects images, the projector comprising:

a projection display module by which the projector projects the images;

a network interface by which the projector can communicate with a network;

a distribution module that distributes screen information through the network interface 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 through the network interface from the client over the network; and

a control signal supply module that, in response to control information received through the network interface from the client over the network in response to the distributed screen information, supplies a control signal to the projection display module that controls the working status of the projection display module based on the control information.

10. The projector according to claim 9, further comprising:

an update module that sends 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 through the network interface to the client over the network.

11. The projector according to claim 9, 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.

12. The projector according to claim 9, wherein the screen information enables the client to display a user interface that includes the working status information.

13. The projector according to claim 12, wherein the screen information allows for the working status information displayed in the user interface to be changed.

14. The projector according to claim 9, wherein the working status information includes information about at least one display characteristic of the image projected by the projection display module.

15. The projector according to claim 14, wherein the display characteristic includes a brightness level of the projected image.

16. The projector according to claim 15, wherein the display characteristic includes a contrast level of the projected image.

17. The projector according to claim 14, wherein the display characteristic includes a contrast level of the projected image.

18. A projector that projects images, the projector comprising:

a projection display module by which the projector projects the images;

a network interface by which the projector can communicate with a network;

a distribution module that distributes screen information through the network interface 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 through the network interface from the client over the network, the screen information enabling the client to generate a user interface that includes the working status information; and

a control signal supply module that (i) receives control information through the network interface from the client over the network, the control information having been input by the client with the user interface, and (ii) supplies a control signal to the projection display module that controls the working status of the projection display module, the control signal being generated based on the received control information.

19. The projector according to claim 18, further comprising:

an update module that sends 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 through the network interface to the client over the network.

20. The projector according to claim 18, 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.

21. The projector according to claim 18, wherein the screen information allows for the working status information displayed in the user interface to be changed.

22. The projector according to claim 18, wherein the working status information includes information about at least one display characteristic of the image projected by the projection display module.

23. The projector according to claim 22, wherein the display characteristic includes a brightness level of the projected image.

24. The projector according to claim 23, wherein the display characteristic includes a contrast level of the projected image.

25. The projector according to claim 22, wherein the display characteristic includes a contrast level of the projected image.
