The present invention relates to an information processing system for registering an image processing apparatus to a server apparatus, the image processing apparatus, an information processing apparatus, the server apparatus, an information processing method, and a storage medium.
An image processing apparatus, such as a digital camera (hereinafter referred to as a camera), has the function of transmitting an image captured by the image processing apparatus to an external web service through wireless communication, such as a communication based on Wi-Fi (registered trademark). Examples of external web services include Facebook (registered trademark) and Google Photos (registered trademark). There is a system that include a camera and a web server (server apparatus) mediating between the camera and an external web service. With the registration of the camera to the web server, the camera is enabled to transmit an image to the web server, and the web server is enabled to transmit an image to the external web service.
To register the camera to the web server, it is necessary to associate the camera with account information for a service provided by the web server. It is known that, to make this association, the user inputs information necessary to register the camera to the web server via the user interface of the camera, and communicates with an information processing apparatus, such as the web server, a smart phone, and a personal computer.
A system discussed in Japanese Patent Application Laid-Open No. 2015-114724 receives an input of a mail address from the user via the user interface of a camera, and registers the camera to a web server by using the input mail address.
In the system discussed in Japanese Patent Application Laid-Open No. 2015-114724, the user needs to operate the camera to input the mail address as described. above. However, a character input operation through the user interface of the camera is generally inferior in operability and therefore consumes much time and effort in comparison with a character input operation with a personal computer or a smart phone.
Furthermore, owners of cameras do not always have a mail account. Thus, the users who do not have a mail account need to create a mail account for the purpose of registering a camera, which degrades the user's convenience.

Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached. drawings.
Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. Configurations described in the following exemplary embodiments are to be considered illustrative, and the present invention is not limited to illustrated configurations.
A first exemplary embodiment of the present invention will be described below.
A control unit 101 controls each unit of the camera 100 according to an input signal and a program (descried below). Instead of the control unit 101 controlling the entire apparatus, a plurality of hardware components may share processing to control the entire apparatus.
An imaging unit 102 includes, for example, an optical lens unit, an optical system for controlling diaphragm, zoom, and focus, and an image sensor for converting light (image) introduced via the optical lens unit into an electrical image signal. As the image sensor, a complementary metal oxide semiconductor (CMOS) sensor or a charge coupled device (CCD) sensor is generally used. Under the control of the control unit 101, the imaging unit 102 converts subject light the image of which is funned by a lens included in the imaging unit 102 into an electrical signal via the image sensor, subjects the signal to noise reduction processing, and outputs digital data as image data. The camera 100 according to the present exemplary embodiment records image data in a recording medium 110 according to the Design Rule for Camera File system (DCF) standard.
A nonvolatile memory 103 which is an electrically erasable rewritable nonvolatile memory stores therein programs (described below) to be executed by the control unit 101 and the like. A work memory 104 is used as a buffer memory for temporarily storing image data captured by the imaging unit 102, as an image display memory for a display unit 106, and as a work area for the control unit 101.
An operation unit 105 functions as a user interface for receiving instructions to the camera 100 from the user. The operation unit 105 includes, for example, a power button for issuing an instruction to turn power of the camera 100 ON and OFF, a release button for issuing an instruction to capture an image, and a playback button for issuing an instruction to reproduce image data. The operation unit 105 further includes operation members, such as a dedicated connection button for starting communication with an external apparatus via a wireless communication unit 111 (described below). The operation unit 105 also includes a touch panel formed on the display unit 106 (described below). The release button includes switches 1 and 2. The switch 1 turns ON when the release button is half-pressed. Thus, the operation unit 105 receives an instruction to perform a shooting preparation operation, such as automatic focus (AF) processing, automatic exposure (AE) processing, automatic white balance (AWB) processing, and flash preliminary emission (EP) processing. The switch 2 turns ON when the release button is fully pressed. Thus, the operation unit 105 receives an instruction to perform image capturing.
The display unit 106 displays a view finder image during image capturing, captured image data, and texts for interactive operations. The display unit 106 also includes indicators that go ON, blink, and go OFF to indicate, for example, the access state of the recording medium 110 (described below) and the communication state of the wireless communication unit 111. The camera 100 does not necessarily need to include the display unit 106. The camera 100 is at least to be connectable to the internal or external display unit 106 and to have a display control function for controlling the display of the display unit 106.
An authentication information generation unit 107 generates authentication information to be used to register the camera 100 to the web server 400. The authentication information includes a random number (described below) and a Quick Response (QR) code (registered trademark). The authentication information generation unit 107 may be provided not as a hardware module but as a software module implemented by the control unit 101.
The recording medium 110 can record the image data output from the imaging unit 102.
The recording medium 110 may be attachable to and detachable from the camera 100 or built in the camera 100. More specifically, the camera 100 is at least to have a method for accessing the recording medium 110.
The wireless communication unit 111 is an interface for connecting to an external apparatus. The camera 100 according to the present exemplary embodiment is able to exchange data with the external apparatus via the wireless communication unit 111. For example, image data generated by the imaging unit 102 can be transmitted to the external apparatus via the wireless communication unit 111. According to the present exemplary embodiment, the wireless communication unit 111 includes an interface for performing communication with an external apparatus based on Wi-Fi (registered trademark) conforming to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard. The control unit 101 controls the wireless communication unit 111 to implement wireless communication with the external apparatus. The communication method is not limited to Wi-Fi (registered trademark) but includes, for example, an infrared communication method. The wireless communication unit 111 is an example of a first wireless communication unit. A smart phone 500 (described below) has a similar hardware configuration to that of the camera 100 described above with reference to
The outer appearance of the camera 100 will be described below.
A nonvolatile memory 403 which is an electrically erasable re writable nonvolatile memory stores therein programs (described below) to be executed by the control unit 401 and information about the camera 100 to be registered.
An authentication information processing unit 410 performs login authentication of the user using the web server 400 from an information processing apparatus, such as the smart phone 500 (described below). In a case where the login authentication is successful, the authentication information processing unit 410 generates an authentication key that uniquely defines an information processing apparatus. The authentication information processing unit 410 performs authentication when a random number is notified from the camera 100. The authentication information processing unit 410 may be provided not as a hardware module but as a software module implemented by the control unit 401.
A communication unit 411 is an interface for connecting to an external apparatus via a public network 300. The web server 400 according to the present exemplary embodiment can exchange data with the camera 100 and the smart phone 500 via the public network 300. According to the present exemplary embodiment, the communication unit 411 is not limited to either wireless or wire lined communication.
Initially, in step M401, the smart phone 500 notifies the web server 400 of the account identifier (ID) and a password to log into the web server 400. The account ID and the password may be stored in the smart phone 500 or input by the user at each login time. In a case where the authentication information processing unit 410 performs the login authentication and the login authentication succeeds, in step M402, the web server 400 generates an authentication key for uniquely identifying the user and then distributes the authentication key to the smart phone 500.
Meanwhile, in response to the camera 100 receiving an instruction to register the camera 100 to the web server 400 from the user via the operation unit 105, then in step M403, the control unit 101 instructs the authentication information generation unit 107 to generate a random number. In step M404, the control unit 101 generates a QR code based on the random number generated in step M403 and a Uniform Resource Locator (URL) to be accessed by the smart phone 500 to perform the authentication processing with the web server 400. After generating a QR code, then in step M405, the control unit 101 instructs the display unit 106 to display the QR code and the random number. In this case, a random number has been described above as an example of identification information, and a QR code has been described as an example of an image representing the identification information, the present invention is not limited thereto. For example, a combination of numbers other than random numbers may be used as identification information, and an image in other than the QR code format may be used as an image representing the identification information.
When the QR code is displayed in step M405, then in step M406, the smart phone 500 captures an image of the QR code. In step M407, the smart phone 500 analyzes the captured QR code to acquire the random number and the URL for authentication. In step M408, the smart phone 500 subsequently accesses the URL for authentication and notifies the web server 400 of the random number and the authentication key distributed from the web server 400 in step M402.
In response to receiving the random number and the authentication key from the smart phone 500, then in step M409, the web server 400 checks whether the same random number has redundantly been received, via the authentication information processing unit 410. Redundant reception in this case includes the reception from the smart phone 500 and the reception from an information processing apparatus other than the smart phone 500. If it is confirmed that the same random number has not redundantly been received, then in step M410, the web server 400 temporarily stores the authentication key and the random number as temporary registration information. In step M411, the web server 400 notifies the smart phone 500 that the temporary registration is completed.
In step M412, the smart phone 500 displays a message indicating that the temporary registration is completed, and prompts the user to continue the registration processing. This guidance to the user includes a message for promoting the user to operate the camera 100. In a case where a duplicated random number is notified from the smart phone 500 in step M408, the web server 400 notifies the smart phone 5000 of a duplication error without performing the temporary registration. Furthermore, the web server 400 erases the temporarily registered information.
After the temporary registration, in step M413, the camera 100 activates the wireless communication unit 111 based on a user operation on the operation unit 105 to start a wireless connection to the web server 400 via the access point 200 and the public network 300. In step M414, the camera 100 notifies the camera 100 of the random number generated in step M403 and information specific (referred to as camera information or “apparatus information”) to the web server 400. Examples of pieces of the information specific to the camera 100 include the serial number of the camera 100, the Media Access Control (MAC) address, and the model ID.
The activation of the wireless communication unit 111 may be performed before step M403. According to the present exemplary embodiment, the camera 100 activates the wireless communication unit 111 in step M413 so that the power consumption of the wireless communication unit 111 is controlled in the period from step M403 to step M412.
In response to receiving the random number, then in step M415, the web server 400 compares the received random number with the random number included in the temporarily stored temporary registration information to determine whether an identical random number is present. If an identical random number is present, then in step M416, the authentication information processing unit 410 generates camera identification information (apparatus identification information) for uniquely identifying the camera 100. In a case where the camera 100 communicates with (uploads image data to) the web server 400 after the registration to the web server 400, the camera 100 transmits image data including the camera identification information. The web server 400 identifies the camera 100 based on the camera identification information. In step M417, the web server 400 subsequently stores the account information and the camera information associated with the authentication key, and the camera identification information in association with one another. The associated information is stored in the nonvolatile memory 403. As a result of this processing, the camera 100 is registered to the web server 400.
After the camera 100 is registered to the web server 400 in step M417, then in step M418, the web server 400 notifies the smart phone 500 that the registration is completed and transmits the camera information. In step M419, the smart phone 500 displays the camera information together with the information that the registration is completed. Here, the smart phone 500 displays the camera information to enable the user to make sure that the camera 100 has been properly registered.
In step M420, the web server 400 notifies the camera 100 that the registration is successful and transmits the camera identification information. In response to receiving a result indicating the successful registration and the camera identification information, then in step M421, the control unit 101 of the camera 100 deactivates the wireless communication unit 111. In step M422, the control unit 101 displays a message indicating that the registration to the web server 400 is successful, a message for prompting the user to confirm whether to store the camera identification information, and the camera information, on the display unit 106. In a case where the user confirms that the camera information displayed on the smart phone 500 in step M419 coincides with the camera information displayed on the camera 100 in step M422, then in step M423, the user selects OK. Thus, in step M424, the control unit 101 stores the camera identification information in the nonvolatile memory 103. After storing the information, then in step M425, the display unit 106 displays a message indicating that the registration is completed.
In a case where the camera information is provided in step M414 before the smart phone 500 captures an image of the QR code in step M406, in other words, before the random number is transmitted from the smart phone 500 to the web server 400 in step M408, the web server 400 notifies the camera 100 that the registration has failed.
In a case where the web server 400 does not receive the random number and the camera information from the camera 100 even after a predetermined time period has elapsed since the web server 400 notified the smart phone 500 that the temporary registration is successful in step 1411, the web server 400 erases the temporary registration information.
In response to receiving an instruction for the registration to the web server 400 from the user via the operation unit 105 of the camera 100, then in step S501, the control unit 101 generates a random number and displays a QR code into which data containing the random number has been coded and the numerical value of the random number itself on the display unit 106.
In response to the operation button 1203 being operated, then in step S502, the control unit 101 activates the wireless communication unit 111 to start a wireless connection with the access point 200. In step S503, the control unit 101 checks whether the wireless connection between the wireless communication unit 111 and the access point 200 is successful. If the connection is successful (YES in step S503), the processing proceeds to step S504. In step S504, the control unit 101 transmits the random number and the camera information to the web server 400 via the wireless communication unit 111 and the public network 300.
In step S505, the control unit 101 then receives the registration result and the camera identification information for uniquely specifying the camera registered by the web server 400 from the web server 400, via the wireless communication unit 111. In step S506, the control unit 101 deactivates the wireless communication unit 111. After deactivating the wireless communication unit 111, then in step S507, the control unit 101 checks whether the registration result indicates the success or failure. If the registration is successful (YES in step S507), the processing proceeds to step S508. In step S508, the control unit 101 displays a message indicating that the registration to the web server 400 is successful, a message for prompting the user to confirm whether to store the camera identification information, and the camera information. In step S509, the user selects OK or Cancel on the operation t 105. This selection operation is intended to prompt the user to confirm whether to register the target camera to the web server 400. If the user selects OK (YES in step S509), the processing proceeds to step S510. In step S510, the control unit 101 stores the camera identification information in the nonvolatile memory 103. In step S511, the control unit 101 causes the display unit 106 to display a message indicating that the registration to the web server 400 is completed.
If the wireless connection has failed (NO in step S503), the processing proceeds to step S512. In step S512, the control unit 101 deactivates the wireless communication unit 111. In step S513, the control unit 101 causes the display unit 106 to display an error message. Here, the display unit 106 displays an error message indicating that the wireless connection has failed.
If it is determined that the registration has failed (NO in step S507), the processing proceeds to step S513. In step S513, the control unit 101 instructs the display unit 106 to display an error message. In this case as well, the processing may proceed to step S512. In step S512, the control unit 101 may deactivate the wireless communication unit 111. Here, the display unit 106 displays a message indicating that the registration to the web server 400 has failed. Possible causes of the error include a case where the temporary registration has not yet been performed by the smart phone 500, a case where the random number and the camera information are not transmitted to the web server 400 even after a predetermined time period has elapsed since the temporary registration is performed so that the effective period expires, and a case where other users have performed the temporary registration based on the same random number. Possible causes of the error further include a case where an access concentration or a system error occurs on the web server 400. Descriptions of the error may be displayed for each of the above-described cases, or only a failure message may be displayed.
If the user selects Cancel (NO in step S509), the processing proceeds to step S511. In step S514, the control unit 101 cancels the camera identification information received from the web server 400. In this case, the camera 100 behaves as a camera unregistered to the web server 400.
Initially, in step S601, the web server 400 receives an account. ID and a password for login from the smart phone 500. In step S602, the authentication information processing unit 410 of the web server 400 generates an authentication key with which a user is uniquely determined based on the received account ID. In step S603, the web server 400 notifies the smart phone 500 of the authentication key.
In step S604, the web server 400 receives the random number and the authentication key from the smart phone 500 that has captured the image of the QR code displayed on the camera 100. In step S605, the authentication information processing unit 410 checks whether another authentication key is registered with the same random number as the one received in step S604, to check whether the temporary registration is possible with the notified authentication key. If the temporary registration is possible, in other words, if the authentication information processing unit 410 determines that no other authentication keys with the same random number is present (YES in step S605), the processing proceeds to step S606. In step S606, the authentication information processing unit 410 stores the authentication key and the random number in the nonvolatile memory 403 in association with each other. In step S607, the web server 400 notifies the smart phone 500 that the temporary registration is successful. In step S608, the control unit 401 activates a timer for checking the effective period of the temporary registration.
In step S609, the web server 400 receives the random number and the camera information from the camera 100 via the communication unit 411. In step S610, the authentication information processing unit 410 checks whether the same random number as the one received in step S609 is present in the temporarily registered authentication keys. If the same random number is present (YES in step S610), the processing proceeds to step S611. In step S611, the control unit 401 checks whether the effective period does not expire. If the effective period does not expire, it is determined that the registration is successful (YES in step S611), the processing proceeds to step S612. In step S612, the control unit 401 generates camera identification information.
After the camera identification information is generated, then in step S613, the control unit 401 stores the account ID and the specific information about the camera 100 received in step S601, and the camera identification information in the nonvolatile memory 403 in association with each other. After storing the information, then in step S614, the control unit 401 notifies the smart phone 500 that the registration of the camera 100 is completed and transmits the specific information for the camera 100. Subsequently, in step S615, the control unit 401 provides information indicating that the registration of the camera 100 is completed and the camera identification information, to the camera 100.
While a description has been provided of an example in which the operations in step S609 and subsequent steps are started after completion of the operations in steps S601 to S608, the operations in steps S601 to S608 may be executed independently of and in parallel with the operations in step S609 and subsequent steps. Thus, the temporary registration may not have been completed at the time of reception of a random number from the camera 100 in step S609. In such a case, a result of the determination in step S610 indicates that the same random number as the one received in step S609 is not present.
If the authentication information processing unit 410 determines that the same random number is registered with another authentication key (NO in step S605), the processing proceeds to step S616. In step S616, the authentication information processing unit 410 erases the temporary registration information for the other authentication key from the nonvolatile memory 403 without storing the authentication key and the random number received in step S604. This prevents the camera 100 from being associated with other unintended users. In step S617, the web server 400 notifies the smart phone 500 and the information processing apparatus that has distributed the other authentication key that the temporary registration has failed because of the duplication of random numbers. On the other hand, in a case where the random number provided by the camera 100 is not found from among the random numbers of the temporarily registered authentication keys (NO in step S610), the processing proceeds to step S618. In step S618, the web server 400 notifies the camera 100 and the smart phone 500 that the temporary registration has failed due to the absence of temporary registration information. If the effective period expires (NO in step S611), the processing proceeds to step S619. In step S619, the control unit 401 notifies the camera 100 and the smart phone 500 that the temporary registration has failed due to the expiration of the effective period. The setting of the effective period reduces the possibility of the duplication of random numbers.
In step S701, the user inputs an account ID and a password on the smart phone 500 and then transmits them to the web server 400. After the transmission, then in step S702, the smart phone 500 receives an authentication key from the web server 400. In step S703, the user subsequently captures an image of the QR code displayed on the camera 100 by using the smart phone 500. In step S704, the smart phone 500 acquires a random number and a URL for authentication based on the read QR code. In step S705, the smart phone 500 transmits the authentication key and the random number to the web server 400. In step S706, the smart phone 500 receives a response from the web server 400 and then checks a result of the temporary registration. If the temporary registration is successful (YES in step S706), the processing proceeds to step S707. In step S707, the smart phone 500 displays a message prompting the user to continue the registration processing with the camera 100.
In step S708, the smart phone 500 subsequently receives the result of the temporary registration of the camera 100 and the specific information for the camera. 100 from the web server 400. In step S709, the smart phone 500 checks whether a definitive registration is successful. When the definitive registration is successful (YES in step S709), the processing proceeds to step S710. In step S710, the smart phone 500 displays a message indicating that the definitive registration is completed and the serial number of the camera 100.
If the temporary registration has failed (NO in step S706), the processing proceeds to step S711. In step S711, the smart phone 500 displays a message indicating that the temporary registration has failed. If the definitive registration has failed (NO in step S709), the processing proceeds to step S712. In step S712, the smart phone 500 checks whether the effective period expires. If the effective period expires (YES in step S712), the processing proceeds to step S713. In step S713, the smart phone 500 displays a message indicating that the effective period expires. If the effective period does not expire (NO in step S712), the processing proceeds to S711. In step S711, the smart phone 500 displays a message indicating that the definitive registration has failed.
As described above, according to the present exemplary embodiment, the smart phone 500 captures an image of the QR code generated and displayed by the camera 100, thus enabling the user to register the camera 100 to the web server 400 without inputting complicated information on the operation unit 105 of the camera 100. More specifically, in an information processing system including the camera 100 (image processing apparatus), the smart phone 500 (information processing apparatus), and the web server 400 (server apparatus), the camera 100 generates a random number (identification information) and displays a QR code (image) representing the generated random number. The camera 100 transmits the generated random number to the web server 400 (first transmission). The smart phone 500 captures an image of the QR code displayed on the camera 100, acquires a random number based on the captured QR code, and transmits the acquired random number to the web server 400 (second transmission). The web server 400 receives the random number transmitted from the camera 100 (first reception), receives the random number transmitted from the smart phone 500 (second reception), and then registers the camera 100 based on the match between the random numbers, thus improving the user's operability.
A second exemplary embodiment of the present invention l be described below. The hardware configurations of the camera 100 and the smart phone 500 are similar to those illustrated in
The operations in steps M901 to M905 are similar to those in steps M401 M405, respectively, in the sequence according to the first exemplary embodiment (
In step M906, the user manually inputs the URL for authentication of the web server 400 by using the personal computer 600 to access the URL. The URL for authentication is assumed to be described in a web page or an instruction manual, or may be displayed on the camera 100. In step M907, the user accesses the URL for authentication by using the personal computer 600 and then inputs the random number displayed on the camera 100.
The operations in steps M908 to M925 are similar to those in steps M408 to M425, respectively, in the sequence according to the first exemplary embodiment (FIG. 5), and redundant descriptions thereof will be omitted.
The operations in steps S1001 and S1002 are similar to those in steps S701 and S702, respectively, in the flowchart according to the first exemplary embodiment (
In step S1003, the user manually inputs the URL for authentication of the web server 400 by using the personal computer 600 to access the URL. After accessing the URL for authentication, then in step S1004, the user inputs the random number displayed on the camera 100 by using the personal computer 600.
The operations in steps S1005 to S1013 are similar to those in steps S705 to S713, respectively, in the flowchart according to the first exemplary embodiment (
According to the present exemplary embodiment, even in a case where the personal computer 600 that cannot read a QR code is used, the camera 100 can be registered to the web server 400 without input of setting information for the registration to the web server 400 through the operation unit 105 of the camera 100, as described above. More specifically, in an information processing system including the camera 100 (image processing apparatus), the smart phone 500 (information processing apparatus), and the web server 400 (server apparatus), the camera 100 generates a random number (identification information) and displays the generated random number. The camera 100 transmits the generated random number to the web server 400 (first transmission). The smart phone 500 receives an input of the random number displayed on the camera 100 from the user, and then transmits the received random number to the web server 400 (second transmission). The web server 400 receives the random number transmitted from the camera 100 (first reception), receives the random number transmitted from the smart phone 500 (second reception), and then registers the camera 100 based on the match between the random numbers, thus improving the user's operability.
Displaying the QR code and the random number in the same screen of the camera 100 eliminates the need of prompting the user to select the use of the smart phone 500 or the personal computer 600, on the camera 100. This simplifies operations of the camera 100, improving the user's operability.
A third exemplary embodiment of the present invention will be described below. The hardware configurations of the camera 100 and the smart phone 500 are similar to those illustrated in
In step S515, the control unit 101 checks whether the cause of error is a busy condition due to an access concentration to the web server 400 (server congestion). If the cause of error is other than the busy condition (NO in step S515), the camera 100 terminates the processing of the registration) the web server 400. If the error is the busy condition (YES in step S515), the processing proceeds to step S516. In step S516, the camera 100 displays a message for prompting the user to select whether to terminate the processing for the registration to the web server 400 on the display unit 106, and receives an instruction from the user. If the user instructs not to terminate the registration processing (NO in step S516), the processing returns to step S502. In this case, the camera 100 maintains the random number generated in step S501. This enables resuming the registration processing without reading the QR code again by using the smart phone 500.
In a case where the registration has failed (NO in step S507), the control unit 101 may determine whether to deactivate the wireless communication unit 111 depending on the cause of error. More specifically, in a case where the cause of error is a busy condition due to an access concentration to the web server 400, the control unit 101 may resume the processing from step S504 without deactivating the wireless communication unit 111. This enables resuming the processing from a state in which the wireless connection between the wireless communication unit 111 and the access point 200 is maintained, making it possible to omit the time period required for the wireless connection.
In step S620, the control unit 401 checks whether an access concentration to the web server 400 occurs. If no access concentration occurs (NO in step S620), the processing proceeds to step S610. If a congestion due to an access concentration to the web server 400 occurs (YES in step S620), the processing proceeds to step S621. In step S621, the control unit 101 transmits an error notification indicating that the congestion in the web server 400 occurs to the camera 100.
As described above, the present exemplary embodiment makes it possible to perform a retry (retransmission) without generating an authentication key again if an error is caused by the server congestion, thus reducing the processing load and operating procedures.
