Abstract

A communication apparatus sets one authentication ID for connecting to a network based on user input, changes the set authentication ID to authentication IDs different from each other with respect to each of a plurality of states for communicating with at least any one of an imaging device and a light emission device in a network to execute a predetermined photographing processing, and communicates with at least any one of the imaging device and the light emission device using the changed authentication IDs with respect to each of a plurality of states to execute the predetermined photographing processing.

Claims

1. A communication apparatus comprising:

a setting unit configured to set, based on user input, one authentication identification (ID) for connecting to a network;

a changing unit configured to change the one authentication ID set by the setting unit to output different authentication IDs that are different from each other with respect to each of a plurality of states for communicating with at least any one of an imaging device and a light emission device in a network to execute a predetermined photographing processing; and

a communication unit configured to use a different authentication ID, output by the changing unit with respect to each of a plurality of states, to communicate with at least any one of the imaging device and the light emission device to execute the predetermined photographing processing.

2. The communication apparatus according to claim 1, wherein, to execute the predetermined photographing processing, the changing unit calculates a different authentication ID by performing a calculation on the one authentication ID set by the setting unit with respect to each of a plurality of states, wherein each calculation is different from other calculations.

3. The communication apparatus according to claim 1, wherein the plurality of states is combinations of a wireless channel mode and a control mode between the communication apparatus and another communication apparatus.

4. The communication apparatus according to claim 3, wherein the wireless channel mode includes at least any one of a mode for automatically setting a wireless channel and a mode for specifying a wireless channel by a user.

5. The communication apparatus according to claim 3, wherein the control mode includes at least any one mode of a flash control mode for controlling light emission of the light emission device as the another communication apparatus, and a linked release mode for linking an image capturing between the communication apparatus and the imaging device as the another communication apparatus.

6. The communication apparatus according to claim 3, wherein, when the wireless channel mode has been changed, the changing unit calculates a different authentication ID by performing calculation using a value of the one authentication ID set by the setting unit and a first value.

7. The communication apparatus according to claim 3 wherein, when the control mode has been changed, the changing unit calculates a different authentication ID by performing calculation using a value of the one authentication ID set by the setting unit and a second value.

8. The communication apparatus according to claim 1, further comprising a display unit configured to display a value of the one authentication ID set by the setting unit, wherein, even when the one authentication ID is changed to a different authentication ID by the changing unit, the display unit displays a value of the one authentication ID set, based on user input, by the setting unit.

11. The communication apparatus according to claim 1, wherein the communication apparatus is detachable to the imaging device.

12. The communication apparatus according to claim 1, wherein the communication apparatus is included in light emission device detachable to the imaging device.

13. The communication apparatus according to claim 1, wherein the communication apparatus is built into the imaging device.

14. The communication apparatus according to claim 1, wherein the one authentication ID is a number.

15. The communication apparatus according to claim 14, wherein the changing unit obtains the different authentication IDs by adding or subtracting predetermined value to/from the one authentication ID.

16. The communication apparatus according to claim 1, wherein the one authentication ID is a character string.

17. The communication apparatus according to claim 16, wherein the changing unit obtains the different authentication IDs by adding or deleting predetermined character string to/from the one authentication ID.

9. A control method for a communication apparatus, the control method comprising:

setting, based on user input, one authentication identification (ID) for connecting to a network;

changing the set one authentication ID to output different authentication IDs that are different from each other with respect to each of a plurality of states for communicating with at least any one of an imaging device and a light emission device in a network to execute a predetermined photographing processing; and

using a different authentication ID, output with respect to each of a plurality of states, to communicate with at least any one of the imaging device and the light emission device to execute the predetermined photographing processing.

10. A non-transitory computer-readable storage medium storing a program to cause a communication apparatus to perform a control method, the control method comprising:

setting, based on user input, one authentication identification (ID) for connecting to a network;

changing the set one authentication ID to output different authentication IDs that are different from each other with respect to each of a plurality of states for communicating with at least any one of an imaging device and a light emission device in a network to execute a predetermined photographing processing; and

using a different authentication ID, output with respect to each of a plurality of states, to communicate with at least any one of the imaging device and the light emission device to execute the predetermined photographing processing.

18. A communication apparatus comprising:

a setting unit configured to set, based on user input, one authentication identification (ID) for connecting to a network;

a determining unit configured to determine different authentication IDs that are different from each other with respect to each of a plurality of states for communicating with at least any one of an imaging device and a light emission device in a network to execute a predetermined photographing processing, wherein the one authentication ID set by the setting unit is changed to determine at least one of the different authentication IDs; and

a communication unit configured to use at least one of the different authentication IDs determined by the determining unit with respect to each of a plurality of states to communicate with at least any one of the imaging device and the light emission device to execute the predetermined photographing processing.

19. The communication apparatus according to claim 18, wherein the plurality of states is combinations of a wireless channel mode and a control mode between the communication apparatus and another communication apparatus.
