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 projector connecting with an external input apparatus having an input unit via a network, said projector comprising:

a network interface module that connects with the network;

a video data generation module that executes a predetermined series of processing with regard to contents of an image to be projected and displayed and generates video data representing the image to be projected and displayed, based on operation information generated through an operation of said input unit of said eternal input device and supplied to said network interface module via the network;

an electro-optic device that generates an image ray according to the video data; and

a projection optical system that projects the image ray generated by said electro-optic device.

2. A projector in accordance with claim 1, wherein the image to be projected and displayed includes an original image and an ornamental image superimposed on the original image,

ornamental video data representing the ornamental image is not supplied from said external input apparatus but is prepared by said video data generation module, and

said video data generation module combines original video data representing the original image with the ornamental video data to generate the video data, based on the operation information supplied from said external storage device, thereby superimposing the ornamental image at a predetermined position on the original image.

3. A projector in accordance with claim 2, wherein the operation information includes at least positional information, which is generated through an operation of a pointing device used as said input unit of said external input apparatus, and

said video data generation module superimposes a pointer image as the ornamental image at the predetermined position on the original image, based on the positional information.

4. A projector in accordance with claim 3, wherein the positional information includes coordinate value information specified by said pointing device.

5. A projector in accordance with claim 3, wherein the operation information further includes switch information generated through an operation of a switch mounted on said pointing device, and

said video data generation module superimposes an ornamental image, which is different from the pointer image, in a specified area on the original image, based on the positional information and the switch information included in the operation information.

6. A projector in accordance with claim 5, wherein the operation information further includes key information generated through an operation of a keyboard as said input device of said external input apparatus, and

said video data generation module superimposes a symbol image as the ornamental image on the original image, based on the key information.

7. A projection display system comprising an external input apparatus and a projector connecting with each other via a network,

said external input apparatus comprising:

an input unit;

an operation information generation module that detects a user'"'"'s operation of said input unit and generates operation information based on a result of the detection; and

a first network interface module that connects with the network and supplies the operation information to said projector via the network,

said projector comprising;

a second network interface module that connects with the network;

a video data generation module that executes a predetermined series of processing with regard to contents of an image to be projected and displayed and generates video data representing the image to be projected and displayed, based on the operation information supplied to said second network interface module via the network;

an electro-optic device that generates an image ray according to the video data; and

a projection optical system that projects the image ray generated by said electro-optic device.

8. A projection display system in accordance with claim 7, the image to be projected and displayed includes an original image and an ornamental image superimposed on the original image,

ornamental video data representing the ornamental image is not supplied from said external input apparatus but is prepared by said video data generation module, and

said video data generation module combines original video data representing the original image with the ornamental video data to generate the video data, based on the operation information supplied from said external storage device, thereby superimposing the ornamental image at a predetermined position on the original image.

9. A projection display system in accordance with claim 8, wherein said input unit comprises a pointing device,

the operation information includes at least positional information generated through an operation of said pointing device, and

said video data generation module superimposes a pointer image as the ornamental image at a predetermined position on the original image, based on the positional information.

10. A projection display system in accordance with claim 9, wherein said external input apparatus further comprises a display unit, and

said operation information generation module causes an operation information generation area, in which the operation information is generated in response to the operation of said pointing device, to be displayed on said display unit, and detects the operation of said pointing device only when a pointer image corresponding to said pointing device is present in the operation information generation area.

11. A projection display system in accordance with claim 10, wherein the operation information generation area is mapped to an image area to be projected and displayed.

12. In an external input apparatus having an input unit, a method of generating operation information that is generated through an operation of said input unit and is supplied to a projector, which is connected to said external input apparatus via a network, said method comprising the steps of:

(a) detecting a user'"'"'s operation of said input unit; and

(b) generating the operation information, based on a result of the detection.

13. A method in accordance with claim 12, wherein said step (a) comprises the steps of:

(a-1) causing an operation information generation area, in which the operation information is generated in response to an operation of a pointing device as said input unit, to be displayed on a display unit incorporated in said external input apparatus; and

(a-2) detecting the operation of said pointing device only when a pointer image corresponding to said pointing device is present in the operation information generation area.

14. In an external input apparatus having an input unit, a computer readable recording medium in which a computer program is recorded, said computer program generating operation information that is generated through an operation of said input unit and is supplied to a projector, which is connected to said external input apparatus via a network,

said computer program causing a computer to attain the functions of:

detecting a user'"'"'s operation of said input unit; and

generating the operation information, based on a result of the detection.

15. A computer readable recording medium in accordance with claim 14, wherein said function of detecting the user'"'"'s operation of said input unit comprises the functions of:

causing an operation information generation area, in which the operation information is generated in response to an operation of a pointing device as said input unit, to be displayed on a display unit incorporated in said external input apparatus; and

detecting the operation of said pointing device only when a pointer image corresponding to said pointing device is present in the operation information generation area.
