Projector probing method, control device, and storage medium

1. A method of probing a projector performed on a projector system, the method comprising the steps of:

probing a plurality of projectors to obtain information indicative of time when each of the plurality of the projectors is powered on;

receiving the information indicative of the time when each of the plurality of projectors is powered on; and

identifying a projector with latest time when the projector powered on among the plurality of projectors based on the information indicative of the time when each of the plurality of projectors is powered on, and

displaying identification information of the projector identified.

2. The method according to claim 1 , further comprising the steps of:

generating a list of identification information of the plurality of projectors tabulated in a descending order of the time when each of the plurality of projectors is powered on, and

displaying the list thus generated.

3. The method according to claim 1 , further comprising the step of:

displaying the time when the identified projector is powered on in correspondence with the identification information of the identified projector.

4. The method according to claim 1 ,

further comprising the step of:

displaying an installation location in correspondence with the identification information of the identified projector.

5. The method according to claim 1 , further comprising the step of:

transmitting an information request requesting the information to two or more of the projectors.

6. The method according to claim 1 , further comprising the step of:

broadcasting a probe request for probing connectable ones of the projectors.

7. A control device having a configuration capable of communicating with a plurality of projectors, comprising:

a communication section adapted to probe the plurality of projectors to obtain information indicative of time when each of the plurality of projectors is powered on;

an identification section adapted to identify a projector with latest time when the projector powered on among the plurality of projectors based on the information indicative of the time when each of the projectors is powered on; and

a display section adapted to display identification information of the projector identified.

8. The control device according to claim 7 , further comprising:

a list generation section adapted to generate a list of the identification information of the plurality of projectors tabulated in a descending order of the time when each of the projectors is powered on,

wherein the display section displays the list thus generated.

9. The control device according to claim 7 , wherein

the display section displays the time when the identified projector is powered on in correspondence with the identification information of the identified projector.

10. The control device according to claim 7 , wherein

the information further includes content regarding an installation location of each of the plurality of projectors, and

the display section displays the installation location in correspondence with the identification information of the identified projector.

11. The control device according to claim 7 , wherein

the communication section further includes an information request transmitting section adapted to transmit an information request requesting the information to two or more of the projectors.

12. The control device according to claim 7 , wherein

the communication section further includes a probe request transmission section adapted to broadcast a probe request for probing connectable ones of the projectors.

13. A non-transitory computer readable storage medium storing a program executed by a control device having a display section and configured to be capable of communicating with a plurality of projectors, the program making the control device perform the steps of:

(a) probing the plurality of projectors to obtain information indicative of time when each of the plurality of projectors is powered on;

(b) identifying a projector with latest time when the projector powered on among the plurality of projectors based on the information indicative of time when each of the plurality of projectors is powered on; and

(c) making the display section display identification information of the projector identified.

14. The non-transitory computer readable storage medium according to claim 13 , the program further making the control device perform the step of:

(d) generating a list of identification information of the plurality of projectors tabulated in a descending order of the time when each of the plurality of projectors is powered on,

wherein in step (c), the display section is made to display the list generated in step (d).

15. The non-transitory computer readable storage medium according to claim 13 , wherein

the information further includes content regarding an installation location of each of the plurality of projectors, and

in step (c) the display section is made to display the installation location in correspondence with the identification information of the identified projector.

16. The non-transitory computer readable storage medium according to claim 13 , wherein

in step (a), an information request requesting the information is transmitted to two or more of the projectors.

17. The non-transitory computer readable storage medium according to claim 13 , wherein

in step (a), a probe request for probing connectable ones of the projectors is broadcasted.
