Abstract

A communication device acquires information relating to a first access point from a captured first image, and acquires information relating to a second access point from a captured second image. The communication device then starts communication parameter share processing of sharing a communication parameter, required for establishing a wireless network, with respect to the first access point or the second access point. The communication device starts the communication parameter share processing with respect to the second access point in response to reception of a completion notification indicative of completion of the communication parameter share processing with respect to the first access point, from the first access point.

Claims

1. A communication device comprising:

a first acquisition unit configured to acquire information relating to a first access point from a captured first image;

a second acquisition unit configured to acquire information relating to a second access point from a captured second image;

a first execution unit configured to execute communication parameter share processing for sharing a communication parameter, required for establishing a wireless network, with the first access point by using the information acquired by the first acquisition unit;

a second execution unit configured to execute the communication parameter share processing, required for establishing a wireless network, with the second access point by using the information acquired by the second acquisition unit; and

a control unit configured to limit acquisition of the information by the second acquisition unit until completion of the communication parameter share processing executed by the first execution unit.

2. The communication device according to claim 1, further comprising:

an image capturing unit configured to capture an image,

wherein the first acquisition unit acquires the information relating to the first access point by analyzing the image captured by the image capturing unit, and

wherein the second acquisition unit acquires the information relating to the second access point by analyzing the image captured by the image capturing unit.

3. The communication device according to claim 1, wherein the information relating to the first access point is information on a public key held by the first access point and identification information on the first access point, and the communication parameter share processing is executed by using the public key and the identification information.

4. The communication device according to claim 1, wherein the communication parameter is a communication parameter of a wireless network established by the first access point and a wireless network established by the second access point.

5. The communication device according to claim 1, wherein the communication parameter includes at least one of a network identifier of the wireless network, an encryption scheme, an encryption key, an authentication scheme, and an authentication key.

6. The communication device according to claim 1, wherein the wireless network is a network of a wireless local area network in conformity with IEEE 802.11 series.

7. The communication device according to claim 2, wherein the image includes a barcode or a two-dimensional code.

10. The communication device according to claim 1, wherein

the control unit performs control such that a mode of capturing an image is not activated until the completion of the communication parameter share processing executed by the first execution unit.

8. A communication method comprising:

firstly acquiring information relating to a first access point from a captured first image;

secondly acquiring information relating to a second access point from a captured second image;

executing communication parameter share processing, required for establishing a wireless network, with the first access point by using the information acquired in the first acquisition;

executing the communication parameter share processing, required for establishing a wireless network, with the second access point by using the information acquired in the second acquisition; and

limiting acquisition of the information acquired in the second acquisition until completion of the executing of the communication parameter share processing, required for establishing a wireless network, with the first access point.

9. A non-transitory computer-readable storage medium storing a program for causing a communication device to execute processes, the processes comprising:

firstly acquiring information relating to a first access point from a captured first image;

secondly acquiring information relating to a second access point from a captured second image;

executing communication parameter share processing, required for establishing a wireless network, with the first access point by using the information acquired in the first acquisition;

executing the communication parameter share processing, required for establishing a wireless network, with the second access point by using the information acquired in the second acquisition; and

limiting acquisition of the information acquired in the second acquisition until completion of the executing of the communication parameter share processing, required for establishing a wireless network, with the first access point.
