Abstract

A communication apparatus includes a first execution unit, a second execution unit, and a selecting unit. The first execution unit performs a first process for setting a wireless parameter, based on information obtained from a captured image. The setting of a wireless parameter is performed between the communication apparatus and another communication apparatus that operates as an access point and that is different from the communication apparatus. The second execution unit performs, based on information obtained from a captured image, a second process for setting a wireless parameter to another communication apparatus that operates as a station and that is different from the communication apparatus. The wireless parameter is one for performing wireless communication with an access point. The selecting unit selects whether the first process or the second process is to be performed, in a case where information is obtained from a first captured image.

First claim

The invention claimed is:

1. A communication apparatus comprising:
one or more processors; and
one or more memories including instructions that, when executed by the one or more processors, cause the communication apparatus to:
capture an image displayed on or associated with another communication apparatus;
determine whether the another communication apparatus is an access point or not in a case where the image is captured;
execute, in a case where the another communication apparatus is an access point, first processing for sharing between the communication apparatus and the another communication apparatus a wireless parameter of a wireless network formed by the another communication apparatus, wherein the first processing is executed based on information that is necessary for wireless parameter setting and is included in the captured image; and
execute, in a case where the another communication apparatus is not an access point, second processing of transmitting Identification information to another access point that enables sharing between the another access point and the another communication apparatus a wireless parameter of a wireless network formed by the another access point, wherein the identification information is included in the information obtained from the captured image.

2. The communication apparatus according to claim 1 , wherein the communication apparatus determines whether the another communication apparatus is an access point or not based on information acquired by analyzing the captured image.

3. The communication apparatus according to claim 1 ,
wherein the communication apparatus displays an error in a case where information acquired by analyzing the captured image does not contain apparatus identification information or a public key as the information that is necessary for the wireless parameter setting.

4. The communication apparatus according to claim 1 , wherein the communication apparatus performs the first processing, the first processing being a process in which the wireless parameter is transmitted through communication with the another communication apparatus indicated by identification information, the identification information being information necessary to set the wireless parameter and being included in the information obtained from the captured image.

5. The communication apparatus according to claim 1 , wherein the image is a bar code or a two-dimensional code.

6. The communication apparatus according to claim 1 , wherein the wireless parameter includes at least one of a service set identifier, an encryption key, an encryption method, an authentication key, and an authentication method.

7. The communication apparatus according to claim 1 , wherein the wireless parameter is information for performing communication in conformity with an IEEE 802.11 series standard.

8. The communication apparatus according to claim 1 , wherein the access point is an access point in an infrastructure mode set forth in an IEEE802.11 standard or a Group Owner set forth in a Wi-Fi Direct standard.

9. A control method for a communication apparatus, the control method comprising:
capturing an image displayed on or associated with another communication apparatus;
determining whether the another communication apparatus is an access point or not in a case where the image is captured;
executing, in a case where the another communication apparatus is an access point, first processing for sharing between the communication apparatus and the another communication apparatus a wireless parameter of a wireless network formed by the another communication apparatus, wherein the first processing is executed based on information that is necessary for wireless parameter setting and is included in information acquired from the captured image; and
executing, in a case where the another communication apparatus is not an access point, second processing of transmitting identification information to another access point that enables sharing between the another access point and the another communication apparatus a wireless parameter of a wireless network formed by the another access point, wherein the identification information is included in the information obtained from the captured image.

10. A non-transitory storage medium storing a program for causing a computer to perform a process comprising:
capturing an image displayed on or associated with another communication apparatus;
determining whether the another communication apparatus is an access point or not in a case where the image is captured;
executing, in a case where the another communication apparatus is an access point, first processing for sharing between the communication apparatus and the another communication apparatus a wireless parameter of a wireless network formed by the another communication apparatus, wherein the first processing is executed based on information that is necessary for wireless parameter setting and is included in information acquired from the captured image; and
executing, in a case where the another communication apparatus is not an access point, second processing of transmitting identification information to another access point that enables sharing between the another access point and the another communication apparatus a wireless parameter of a wireless network formed by the another access point, wherein the identification information is included in the information obtained from the captured image.
