Abstract

A method includes sending image related working status information representing image-related working status of a projector that projects images, to a client over a network in response to a request to provide the image-related working status of the projector. The image-related working status is related to display characteristic of the projected image. The method includes controlling the image-related working status of the projector based on the control information received from the client over the network in response to the sent image-related working status information. The image-related working status information is sent to the client with screen information from which the client can display a user interface that includes the image-related working status information.

Claims

1. A network-connectable projector, comprising:

a projection display module by which the projector projects images;

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

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

a second controller portion that controls a working state of the projector; and

a second memory portion that stores working state information representing the working state, wherein the working state information includes information about at least one display characteristic of the image projected by the projection display module, wherein

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

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

the first controller portion makes the second controller portion 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 controller portion transfers the controlled working state information to the first controller portion after controlling the working state of the projector, and

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

3. A projector in accordance with claim 1, wherein

the second controller portion stores the controlled working state information in the second memory portion 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 controller portion 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 controller portion and the first memory portion constitute a web server module, and

the first controller portion executes controlling a working state of the web server module, or the working state of the projector via the second controller portion, 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 projection display module by which the projector projects images;

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

a second memory portion that stores working state information representing a working state of the projector,wherein the working state information includes information about at least one display characteristic of the image projected by the projection display module;

a first controller portion; and

a second controller portion that controls the working state of the projector, wherein the second controller portion obtains the working state information from the second memory portion, and transfers the working state information to the first controller portion,

the first controller portion

executes the web application program stored in the first memory portion,

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

makes the second controller portion 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.
