Abstract

A network system of a projector is provided in which a network connection is established between a plurality of information terminal apparatus and the projector, and an image data file owned by an information terminal apparatus can be commonly used. A network system of a projector is arranged by an information terminal apparatus and a projector connectable to the information terminal apparatus via a network. The information terminal apparatus is arranged by a personal computer which supplies image data to the projector, and personal computers which are connected to this personal computer by a wireless manner. When the network connection is established between the personal computer and the projector, and when the network connection between the personal computer and the personal computers is established, the image data is commonly used among these personal computers.

Claims

1. A network system, comprising:

a projector; and

a plurality of information terminal apparatuses that share image data, each information terminal apparatus displays an image based on the shared image data, wherein

at least one of the plurality of information terminal apparatuses allows the projector to display an image based on the shared image data.

2. The network system according to claim 1, wherein

the projector and the plurality of information terminal apparatuses are connected to a wireless network.

3. The network system according to claim 1, wherein the plurality of information terminal apparatuses include:

a first information terminal apparatus which selects an image data to be shared; and

a second information terminal apparatus which shares the image data selected by the first information terminal apparatus.

4. The network system according to claim 3, wherein

the second information terminal apparatus shares the image data after inputting a password.

5. The network system according to claim 1, wherein

each of the plurality of information terminal apparatuses selects an image data to be shared.

6. A method comprising:

sharing image data by a plurality of information terminal apparatuses;

displaying an image based on the shared image data by each of the plurality of information terminal apparatuses; and

allowing a projector to display an image based on the shared image data by at least one of the plurality of information terminal apparatuses.

7. The method according to claim 6, wherein

the projector and the plurality of information terminal apparatuses are connected to a wireless network.

8. The method according to claim 6, the plurality of information terminal apparatuses include:

a first information terminal apparatus which selects an image data to be shared; and

a second information terminal apparatus which shares the image data selected by the first information terminal apparatus.

9. The method according to claim 8, wherein

the second information terminal apparatus shares the image data after inputting a password.

10. The method according to claim 6, wherein

each of the plurality of information terminal apparatuses selects an image data to be shared.

11. A computer-readable storage medium storing a program, the program comprising instructions for:

sharing image data by a plurality of information terminal apparatuses;

displaying an image based on the shared image data by each of the plurality of information terminal apparatuses; and

allowing a projector to display an image based on the shared image data by at least one of the plurality of information terminal apparatuses.

12. The storage medium according to claim 11, wherein

the projector and the plurality of information terminal apparatuses are connected to a wireless network.

13. The storage medium according to claim 11, the plurality of information terminal apparatuses include:

a first information terminal apparatus which selects an image data to be shared; and

a second information terminal apparatus which shares the image data selected by the first information terminal apparatus.

14. The storage medium according to claim 13, wherein

the second information terminal apparatus shares the image data after inputting a password.

15. The storage medium according to claim 11, wherein

each of the plurality of information terminal apparatuses selects an image data to be shared.
