Abstract

A network-connectable projector having a first CPU that executes a web application program stored in a first memory, and a second CPU that controls a working state of the projector, based on working state information stored in a second memory. The second CPU obtains the working state information from the second memory, and transfers the information to the first CPU. The first CPU distributes the web page information including the working state information received from the second CPU to the web client upon receipt of the request from the web client. The first CPU makes the second CPU control the working state of the projector, based on control information that is sent back from the web client and is related to performance control of the projector.

Claims

1. A network-connectable projector, comprising:

a first memory that stores a web application program for distributing web page information to a web client;

a first CPU that executes the web application program stored in the first memory;

a second CPU that controls a working state of the projector; and

a second memory that stores working state information representing the working state, wherein

the second CPU obtains the working state information from the second memory, and transfers the information to the first CPU.

the first CPU distributes the web page information including the working state information received from the second CPU to the web client upon receipt of the request from the web client, and

the first CPU makes the second CPU to control the working state of the projector, based on control information that is sent back from the web client and is related to performance control of the projector.

2. A projector in accordance with claim 1, wherein

the second CPU transfers the controlled working state information to the first CPU after controlling the working state of the projector, and

the first CPU distributes the web information including the controlled working state information received from the second CPU to the web client.

3. A projector in accordance with claim 1, wherein

the second CPU stores the controlled working state information in the second memory after controlling the working state of the projector.

4. A projector in accordance with claim 1, wherein

the working state includes an audio-related working state, the projector further comprising:

an audio control circuit that controls the audio-related working state.

5. A projector in accordance with claim 1, wherein

the working state includes an image-related working state, the projector further comprising:

an image control circuit that controls the image-related working state.

6. A projector in accordance with claim 5, wherein

the image-related working state includes at least one of brightness, contrast, sharpness and gamma correction.

7. A projector in accordance with claim 1, wherein

the working state includes a working state related to a projector installation environment, and

the second CPU controls the working state of the projector in accordance with the working state related to the projector installation environment.

8. A projector in accordance with claim 1, wherein

the first CPU and the first memory constitute a web server module, and

the first CPU executes controlling a working state of the web server module, or the working state of the projector via the second CPU, in accordance with the control information that is sent back from the web client.

9. A method of controlling a network-connectable projector comprising:

a first memory that stores a web application program for distributing web page information to a web client;

a second memory that stores working state information representing a working state of the projector;

a first CPU; and

a second CPU that controls the working state of the projector, wherein

the second CPU obtains the working state information from the second memory, and transfers the information to the first CPU,

the first CPU

executes the web application program stored in the first memory,

distributes the web page information including the working state information received from the second CPU to the web client upon receipt of the request from the web client, and

makes the second CPU to control the working state of the projector, based on control information that is sent back from the web client and is related to performance control of the projector.

10. A network-connectable projector, comprising:

a first memory that stores a web application program for distributing web page information to a web client;

a processing module that executes the web application program stored in the first memory, and controls a working state of the projector; and

a second memory that stores working state information representing the working state, wherein

the processing module obtains the working state information from the second memory, distributes the web page information including the working state information to the web client upon receipt of the request from the web client, and controls the working state of the projector, based on control information that is sent back from the web client and is related to performance control of the projector.

11. A projector in accordance with claim 10, wherein

the processing module distributes the web page information including the controlled working state information to the web client after controlling the working state of the projector.

12. A projector in accordance with claim 10, wherein

the processing module stores the controlled working state information in the second memory after controlling the working state of the projector.

13. A projector in accordance with claim 10, wherein

the working state includes an audio-related working state, the projector further comprising:

an audio control circuit that controls the audio-related working state.

14. A projector in accordance with claim 10, wherein

the working state includes an image-related working state, the projector further comprising:

an image control circuit that controls the image-related working state.

15. A projector in accordance with claim 14, wherein

the image-related working state includes at least one of brightness, contrast, sharpness and gamma correction.

16. A projector in accordance with claim 10, wherein

the working state includes a working state related to a projector installation environment, and

the processing module controls the working state related to the projector installation environment.

17. A method of controlling a network-connectable projector comprising:

a first memory that stores a web application program for distributing web page information to a web client;

a second memory that stores working state information representing a working state of the projector; and

a processing module, wherein

the processing module

obtains the working state information from the second memory,

executes the web application program stored in the first memory,

distributes the web page information including the working state information to the web client upon receipt of the request from the web client, and

controls the working state of the projector, based on control information that is sent back from the web client and is related to performance control of the projector.
