Description

[Technical Field]

[0001] The present invention relates to a technique for improving the efficiency of settings for an imaging device. [Background technology]

[0002] A photographing device such as a digital camera can capture different images of the same subject by adjusting the settings of the photographing functions used when photographing. Examples of photographing function settings include shutter speed, aperture value, color tint, color tone, ISO sensitivity, white balance, color balance, and sharpness, and two or more possible setting values ​​can be set for each setting. ISO is an abbreviation for International Organization for Standardization. The setting values ​​may be analog continuous values ​​or digital discrete values.

[0003] Generally, an advanced user who is familiar with using an imaging device can capture the image that the user wants to obtain by mastering these various settings. On the other hand, a beginner user who is not familiar with using an imaging device may not be able to master these various settings and may not be able to capture the image that the user wants to obtain. For example, when there are a large number of setting items and configurable setting values ​​that can be used in imaging, the image that is captured changes depending on the combination of these setting items and setting values, and it may be difficult for the user to find an appropriate combination for capturing the image that the user wants to obtain.

[0004] For example, suppose a user sees a photo of a waterfall displayed on a poster at a tourist spot or in a travel brochure and wants to take a similar photo. In this case, the user can take a photo similar to the photo on the poster or brochure by photographing the subject at the actual location with the same angle of view. However, if the settings used to configure the camera are different from those used when the poster or brochure photo was taken, the photo taken by the user may differ from the photo on the poster or brochure. Some camera devices are provided with preset combinations of settings associated with shooting modes. The user can switch the settings of the camera device by selecting one of these preset combinations depending on the subject to be photographed and the shooting situation. However, the number of preset combinations is limited, and they do not necessarily match the combinations of settings used when the poster or brochure photo was taken. Thus, when a camera device has a large number of settings and combinations of configurable settings available to users, it may be difficult to identify the combination that will allow a specific user to capture the image they want. In response to this issue, for example, Patent Document 1 describes a technology that uses a two-dimensional code or the like to provide the combinations of settings used when the poster or brochure photo was taken.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-174043 Summary of the Invention [Problem to be solved by the invention]

[0006] When a combination of settings of a camera used to capture an image on a printed material such as a poster or pamphlet is provided using a two-dimensional code or the like, the two-dimensional code or the like may be printed on the printed material along with the image. For example, information identifying each setting of the camera may be embedded in the two-dimensional code and provided. In this case, a user can set the identified parameters in the camera by reading the two-dimensional code using the camera to be configured. This allows the user to set the settings used to capture the image in the camera without having to search for the settings by trial and error. However, if changes or additions are made to these settings, the printed material must be reprinted in order to change the two-dimensional code or the like printed on the printed material.

[0007] To provide a technique capable of providing a user with setting values ​​of a photographing device associated with an image printed on a printed matter, without the need to reprint the printed matter, even if the setting values ​​are added or changed. [Means for solving the problem]

[0008] According to one aspect of the present invention, a photographing device having an imaging means includes: an identification means for identifying an access destination associated with an information processing device to be accessed in order to obtain predetermined setting information associated with settings used by another photographing device in photographing, based on reading of a predetermined printed matter including at least a predetermined image obtained by photographing with the other photographing device; an acquisition means for acquiring the predetermined setting information by communicating with the information processing device via the access destination; and a setting means for configuring the photographing means using the predetermined setting information. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a user with the setting values ​​of a photographing device associated with an image printed on a printed matter, even if the setting values ​​are added or changed, without the need to reprint the printed matter.

[0011] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention claimed. Although multiple features are described in the embodiments, not all of these multiple features are necessarily essential to the invention, and multiple features may be combined arbitrarily. Furthermore, in the accompanying drawings, the same reference numerals are used to designate the same or similar components, and redundant explanations will be omitted.

[0012] (System Configuration) FIG. 1 shows an example of the configuration of an information processing system according to this embodiment. The information processing system may be configured with an image capturing device 101 and an information processing device 111. The image capturing device 101 and the information processing device 111 are connected via a network 121 and are capable of communicating with each other. The network 121 may be a combination of a general public mobile communication network and the Internet, or may be a wireless LAN (Local Area Network), a wired LAN, a fixed telephone network, or the like. A combination of multiple networks may also be used. Note that FIG. 1 shows an example of a configuration in which there is one image capturing device 101 and one information processing device 111, but there may be multiple image capturing devices 101 and multiple information processing devices 111.

[0013] The photographing device 101 is a device capable of photographing an image. For example, the photographing device 101 may be a digital camera, a digital video camera, or the like. The photographing device 101 is not limited to these, and may be any device having a photographing function, such as a mobile phone with a camera function, a smartphone with a camera function, a tablet with a camera function, or a personal computer (PC) with a camera function.

[0014] The information processing device 111 is a server device that provides various services to the image capturing device 101. For example, the information processing device 111 may provide a service of receiving data of an image captured by the image capturing device 101 from the image capturing device 101 and storing the data. The information processing device 111 may also provide a service of transmitting data stored in the information processing device 111 to the image capturing device 101 or another device in response to a user request. The services provided by the information processing device 111 are not limited to these, and any service that can be used by a user to use the image capturing device 101 may be provided.

[0015] The subject 131 is an object that the user photographs using the imaging device 101. For example, the subject 131 may be a natural landscape, a flower, an insect, an animal, a person, a building, a train, an airplane, etc. The subject 131 is not limited to these, and may be any object that the user photographs using the imaging device 101.

[0016] The printed matter 141 is a printed matter on which an image acquired by photographing the subject 131 is printed. For example, the printed matter 141 may be a poster or a pamphlet. The printed matter 141 is not limited to these, and may be any medium on which an image can be printed or posted, such as paper or a signboard.

[0017] When a user photographs a subject 131 using the photographing device 101, the user can capture a variety of different images of the same subject 131 by changing the settings of various photographing settings of the photographing device 101. The settings may also be referred to as parameters. For example, the photographing device 101 may be configured with settings such as aperture value, shutter speed, and ISO sensitivity to adjust the brightness of the image. The aperture value may adjust the amount of light passing through the lens. The shutter speed may adjust the amount of time light is exposed to the sensor or film. The ISO sensitivity may adjust the sensitivity of the sensor to light. ISO is an abbreviation for International Organization for Standardization. For example, a faster shutter speed may be set when photographing a fast-moving subject, and a slower shutter speed may be set when photographing in a dark location. For example, a lower aperture value may be set when photographing at night or indoors in poor lighting conditions, and a higher aperture value may be set when photographing a landscape or other photography where the entire image needs to be in focus. These settings affect each other, so if the combination of the respective setting values ​​is not set appropriately, the image the user wants to capture may not be captured. For example, if the aperture value is set large, the shutter speed is set fast, and the ISO sensitivity is set low, the image may be dark, and the subject may not be captured properly. Furthermore, for example, the image capture device 101 may adjust the white balance and color balance to adjust the color tone and hue of the image. Furthermore, for example, the image capture device 101 may adjust the sharpness to emphasize or blur the contours of the subject. The image capture setting items possessed by the image capture device 101 are not limited to these, and any setting items for image capture may be provided, and each setting item may be set to an appropriate setting value depending on the image the user wants to capture.

[0018] For example, if a user wants to capture an image similar to the image printed on the printed material 141, the same circumstances as when the image was captured must be reproduced. For example, if the image is a landscape, the user adjusts the distance and angle between the image capturing device 101 and the subject 131 so that the angle of view is the same as when the image printed on the printed material 141 was captured at the location where the image printed on the printed material 141 was captured, and sets the image capturing device 101 to the same settings used for the capture. As described above, there are a variety of settings available for use in the image capturing settings of the image capturing device 101, and the settings affect each other. For this reason, it is difficult for a user who is unfamiliar with using the image capturing device 101 to identify, by trial and error, the combination of settings used when the image printed on the printed material 141 was captured. In response to this, for example, if the settings used when the image was captured are provided on the printed material 141, the user can use these settings to configure the image capturing device 101. For example, information indicating the settings used when the image was captured may be provided as a two-dimensional code. In this case, the user can read the two-dimensional code using the image capture device 101 and analyze the read two-dimensional code to obtain the setting values ​​used when the image was captured. These setting values ​​can then be set in the image capture device 101. For example, the two-dimensional code can be a QR code (registered trademark). In this case, if the image capture device 101 has a QR code reader function, the QR code read on the printed material 141 can be analyzed to obtain the setting values ​​used when the image was captured, and the setting values ​​can be used to configure the image capture device 101. Alternatively, different setting values ​​can be generated based on the setting values ​​used when the image printed on the printed material 141 was captured, and these setting values ​​can be provided as a two-dimensional code. For example, if there are multiple models of image capture devices 101, setting values ​​corresponding to each of these models can be generated and provided as two-dimensional codes. In this way, by providing the setting values ​​used for capturing the image and the setting values ​​generated based on these setting values ​​along with the image, the user can easily capture an image by recreating the same conditions as when the image was captured.However, with the above-described method, if it becomes necessary to change the two-dimensional code after printing the printed matter 141, it is necessary to reprint the printed matter 141. For example, if a new model is manufactured and sold after the printed matter 141 is printed, it is necessary to reprint the printed matter 141 in order to provide a combination of setting values ​​corresponding to this model. On the other hand, if the printed matter 141 does not provide a combination of setting values ​​for the new model, the user of the new model must find the parameter combination by trial and error.

[0019] In consideration of these circumstances, the photographing device 101 in this embodiment identifies an access destination for acquiring predetermined setting information based on the reading of a predetermined printed material including a predetermined image, and acquires the predetermined setting information by communicating with an information processing device via the access destination. The photographing device 101 then configures its own device using the acquired setting information. The predetermined setting information is setting information associated with settings used in photographing performed using another photographing device to acquire the predetermined image. For example, the predetermined setting information may be setting values ​​used in the photographing or setting values ​​for another model generated based on the setting values. The access destination is also an access destination associated with the information processing device. For example, the access destination may be indicated by a uniform resource identifier (URI). With this configuration, even if the setting information is added or changed, the updated setting information can be provided to the photographing device 101 by adding or changing the setting information stored in the information processing device without reprinting the printed material.

[0020] For example, first information may be provided that is printed separately from a predetermined image on a predetermined printed material. In this case, the photographing device 101 may read the first information and identify the access destination using the read first information. The first information may be, for example, a QR code. With this configuration, the photographing device 101 can access the information processing device based on the access destination information included in the QR code and acquire setting information.

[0021] For example, second information for specifying an access destination may be embedded in a predetermined image printed on a predetermined printed material. In this case, the image capturing device 101 reads the second information embedded in the predetermined image, and can access the information processing device based on the access destination information indicated by the second information, thereby acquiring the setting information. Note that the reading of the second information may be performed by another terminal device. In this case, the image capturing device 101 can acquire the access destination specified by the second information read by the terminal device, and can access the information processing device based on the access destination information, thereby acquiring the setting information.

[0022] The device configuration, functional configuration, and processing flow of the image capturing device 101 and information processing device 111 of this embodiment will be described below.

[0023] (Device configuration) FIG. 2 shows an example of the hardware configuration of the image capturing device 101 of this embodiment. The image capturing device 101 includes a control unit 201, an input unit 202, an output unit 203, a storage unit 204, an image sensor 205, a communication control unit 206, a GPS 207, and an LCD 208.

In FIG. 2, the control unit 201 includes a CPU, ROM, RAM, a timer, peripheral devices, and the like, and controls the entire image capturing device 101. CPU stands for Central Processing Unit. ROM stands for Read Only Memory. RAM stands for Random Access Memory. The input unit 202 includes a user interface such as a touch panel, buttons, and dials, and accepts various inputs, including user instructions and setting values ​​input to the image capturing device 101. The output unit 203 includes an interface for output using the LCD 208, and provides the user with output such as captured images, the status of the image capturing device 101, and processing results. The output unit 203 may provide the user with output, such as setting items that can be set in the image capturing device 101, setting values ​​currently being set, and setting values ​​that can be set, when setting the image capturing device 101. The storage unit 204 may be configured with an interface that controls access to a flash memory and the flash memory. The image sensor 205 receives light that has passed through a lens and converts it into an electrical signal, which is then converted into image data. The communication control unit 206 includes a communication interface that enables the image capturing device 101 to communicate with the network 121 and controls communication when the image capturing device 101 communicates with other devices, such as the information processing device 111, via the network 121. Examples of the communication interface may include, but are not limited to, a wireless LAN, a fifth-generation mobile communication system (5G), etc. For example, the communication interface may include Bluetooth (registered trademark), Near Field Communication (NFC), etc. The GPS 207 uses a satellite positioning system to measure the current location of the image capturing device 101 on Earth and record the location as attribute information of the captured image data. The LCD 208 displays the information output from the output unit 203 to the user.A system bus 209 connects the above-mentioned components so that they can communicate with each other.

[0024] FIG. 3 shows an example of the hardware configuration of the information processing device 111 of this embodiment. The information processing device 111 includes a control unit 301, an input unit 302, an output unit 303, a communication control unit 304, and a storage unit 305. The control unit 301 includes a CPU, a ROM, a RAM, peripheral devices, etc., and controls the entire information processing device 111. The input unit 302 includes an interface for connecting a keyboard, a mouse, etc., and receives instructions and various inputs from a user to the information processing device 111. The output unit 303 includes an interface for connecting a display, etc., and controls output of the status of the information processing device 111, processing results, etc. The communication control unit 304 includes an interface for communicating with the network 121, and controls communication with other devices via the network 121. The storage unit 305 includes an interface for controlling access to a mass storage device. A system bus 306 connects the above-mentioned components to each other so that they can communicate with each other.

[0025] FIG. 4 shows an example of the functional configuration of the image capturing device 101 of this embodiment. The image capturing device 101 may include an image capturing unit 401, an access destination identification unit 402, a setting information acquisition unit 403, and a setting control unit 404. The image capturing unit 401 captures an image using the image sensor 205. The image capturing unit 401 has various setting items, and setting values ​​for each setting item are set by the setting control unit 404. The image capturing unit 401 captures an image based on the set setting values ​​and acquires an image. The access destination identification unit 402 identifies an access destination to be accessed in order to acquire setting information for configuring the image capturing unit 401. For example, the access destination identification unit 402 may identify the access destination by analyzing an image read by the image capturing unit 401. The setting information acquisition unit 403 acquires the setting information. For example, the setting information acquisition unit 403 acquires the setting information by communicating with the information processing device 111 using the communication control unit 204 via the access destination identified by the access destination identification unit 402. The setting control unit 404 sets the image capturing unit 401. For example, the setting control unit 404 sets the image capturing unit 401 using the setting information acquired by the setting information acquisition unit 403.

[0026] FIG. 5 shows an example of the functional configuration of the information processing device 111 of this embodiment. The information processing device 111 may include a setting information storage unit 501, a request receiving unit 502, and a setting information providing unit 503. The setting information storage unit 501 stores setting information of an image capture device. For example, the setting information storage unit 501 may store information associated with the setting information of an image capture device used to capture a specific image. As an example, the setting information storage unit 501 may store setting information corresponding to a combination of each specific image and each model of an image capture device. The request receiving unit 502 receives a request for providing setting information. The request receiving unit 502 may receive a request from, for example, the image capture device 101 or another device. The setting information providing unit 503 provides setting information. For example, the setting information providing unit 503 may provide setting information in response to a request for providing setting information received by the request receiving unit 502. When the setting information providing unit 503 acquires information identifying a combination of a specific image and a model in the request, it may provide setting information corresponding to that combination.

[0027] FIG. 6 shows an example of the configuration of a printed matter 141 according to this embodiment. The printed matter 141 may include an image 601 acquired by photographing a subject 131 and a two-dimensional code 602. The printed matter 141 may also include other components, such as an explanation related to the subject 131. The printed matter 141 may also include multiple images 601, in which case a two-dimensional code 602 corresponding to each of the multiple images 601 may be included. For example, the printed matter 141 may include multiple images 601 acquired by photographing each of multiple different subjects 131. Two or more two-dimensional codes 602 may also correspond to one image 601. For example, the printed matter 141 may include two or more two-dimensional codes 602 corresponding to one or more models of the image capture device 101 for one image 601. The two-dimensional code 602 may include information indicating an access destination to be accessed in order to obtain predetermined setting information associated with the setting values ​​used to capture the subject 131 in the image 601. The information indicating the access destination may be, for example, a URI. A URI may be an identifier for uniquely identifying each file on the network 121. A URI may include, for example, a uniform resource locator (URL) or a uniform resource name (URN). The predetermined setting information may be setting values ​​used to capture the subject 131 of the image 601, or other setting values ​​generated based on these setting values. For example, the setting information may be setting values ​​for a different model of camera used to capture an image similar to the image 601. The two-dimensional code 602 may be, for example, a QR code. The two-dimensional code 602 is not limited to this and may be replaced with any information that may include information indicating a destination to be accessed to acquire the predetermined setting information for the image 601. For example, a one-dimensional code or text information indicating a URI may be used instead of the two-dimensional code. The two-dimensional code 602 may be integrated with the image 601 and placed on the image 601. Furthermore, instead of the two-dimensional code 602, information indicating an access destination to be accessed in order to obtain predetermined setting information may be embedded in the image 601.For example, information indicating the access destination to be accessed in order to obtain predetermined setting information can be embedded in the image 601 as a digital watermark.

[0028] (Processing flow) The following describes the flow of processing executed by the image capturing device 101 and the information processing device 111 for the image capturing device 101 to acquire setting information. FIG. 7 shows an example of a sequence of messages exchanged between the image capturing device 101 and the information processing device 111 of this embodiment for the image capturing device 101 to acquire setting information. This sequence may start, for example, when the image capturing device 101 is turned on and pointed toward the printed material 141. When the image capturing device 101 detects that a two-dimensional code 602 is printed on the printed material 141, it reads the two-dimensional code (F701). For example, if the two-dimensional code 602 is a QR code, the image capturing device 101 may detect the two-dimensional code 602 based on the presence of a predetermined finder pattern on the printed material 141. For example, the image capturing device 101 may display on the LCD 208 that the two-dimensional code has been detected and receive a user input regarding whether or not to access the information processing device 111. In this way, the image capturing device 101 can access the information processing device 111 based on the reading of the detected two-dimensional code 602 .

[0029] The camera apparatus 101 accesses the information processing device 111 via an access destination identified based on the two-dimensional code 602. For example, the camera apparatus 101 can access the information processing device 111 by accessing the URI indicated by the two-dimensional code 602. When accessing the information processing device 111, the camera apparatus 101 can request the provision of setting information (F702). Upon receiving the request for provision of setting information from the camera apparatus 101, the information processing device 111 can provide the setting information to the camera apparatus 101 (F703).

[0030] When the image capturing apparatus 101 receives the setting information from the information processing device 111, it can use the setting information to configure its own device (F704). When the image capturing apparatus 101 has completed configuring its own device, it can notify the user. For example, the image capturing apparatus 101 can display on the LCD 208 that the configuration of its own device has been completed.

[0031] The access destination may differ for each model of the image capturing device 101. For example, the information processing device 111 may store setting information corresponding to each model of the image capturing device 101. Furthermore, if multiple different access destinations are provided corresponding to different models of image capturing devices, the information processing device 111 may accept a request for provision of setting information via the access destination corresponding to each model. In this case, the two-dimensional code 602 may include information indicating the access destination corresponding to each model. The image capturing device 101 may select information indicating the access destination corresponding to its own device model from the information indicating multiple access destinations included in the read two-dimensional code 602, and request provision of setting information from the information processing device 111 via that access destination. If a different two-dimensional code 602 is provided for each model, the image capturing device 101 may select the access destination corresponding to that model by reading the two-dimensional code 602 corresponding to its own device model. The information processing device 111 may identify the access destination from which the request was accepted, thereby determining which model of the image capturing device to provide setting information for. On the other hand, if a common access destination is provided for multiple models of image capturing devices, the image capturing device 101 may request the information processing device 111 to provide setting information via that access destination regardless of the model of the image capturing device itself. In this case, the image capturing device 101 may notify the information processing device 111 of information identifying the model of the image capturing device itself. For example, the image capturing device 101 may notify the information processing device 111 by including information identifying the model of the image capturing device itself in a message requesting setting information. The information processing device 111 may provide the image capturing device 101 with setting information corresponding to the notified model.

[0032] The access destination may be different for each image 601 printed on the printed material 141. For example, the information processing device 111 may store setting information corresponding to each image 601. Furthermore, if different access destinations are provided corresponding to each of the multiple images 601, the information processing device 111 may accept a request for provision of setting information via each access destination. In this case, the two-dimensional code 602 may include information indicating the access destination corresponding to each image 601. The image capturing device 101 may request provision of setting information from the information processing device 111 via the access destination indicated by the read two-dimensional code 602. The information processing device 111 may determine which image 601 is being requested to provide setting information for by identifying the access destination that accepted the request. On the other hand, if a common access destination is provided for the multiple images 601, the image capturing device 101 may request provision of setting information from the information processing device 111 via that access destination. In this case, the image capturing device 101 may notify the information processing device 111 of identification information identifying the image 601. The information processing device 111 may provide the image capturing device 101 with setting information corresponding to the image 601 identified by the notified identification information. The identification information identifying the image 601 may be, for example, identification information that uniquely identifies the image 601. The identification information identifying the image 601 may be included in the two-dimensional code 602. For example, the image capturing device 101 may notify the image capturing device 101 by including the identification information identifying the image 601 in a message requesting setting information. Note that the setting information for each model may be generated based on the setting information of the model used for capturing. For example, if a specific setting item of a specific model is also present in the model used for capturing, the same setting value as that of the model used for capturing may be used for that specific setting item. If a specific setting item of a specific model is not present in the model used for capturing, a default value set for that specific model may be used for that specific setting item.

[0033] The flow of processing executed by the image capturing apparatus 101 to acquire setting information will be described. FIG. 8 shows an example of a processing flow executed by the image capturing apparatus 101 of this embodiment. This flow can start when the image capturing apparatus 101 is turned on (S801). When the image capturing apparatus 101 is turned on, it determines its operation mode and performs an operation corresponding to the operation mode (S802). For example, the image capturing apparatus 101 can be switched to one of a plurality of operation modes in response to a user input. The plurality of operation modes can include a setting mode, a still image capturing mode, a video capturing mode, etc. The setting mode can be an operation state in which the image capturing apparatus 101 is configured. The still image capturing mode can be an operation state in which still images are captured. The video capturing mode can be an operation state in which video is captured. The operation modes (operating states) that the image capturing apparatus 101 can take are not limited to these, and other operation modes can also be included. For example, the still image capture mode and the video capture mode may each be further subdivided into multiple capture modes. The image capture device 101 may have preset setting values ​​corresponding to each capture mode. If the image capture device 101 is not in the setting mode (NO in S802), it executes an operation according to the operation mode of the image capture device 101. For example, if the image capture device 101 is in the still image capture mode or the video capture mode, it executes a capture process (S810). In this case, the image capture device 101 enters a standby state until a user operation is input, and may capture an image of a subject in response to the user operation.

[0034] When the photographing device 101 is in a setting mode (YES in S802), it can read an image or the like on a printed material (S803). For example, the photographing device 101 can have multiple setting modes, such as a setting mode that accepts manual setting by a user and a setting mode that performs setting based on a read image. Here, the setting mode that performs setting based on a read image will be described. For example, the photographing device 101 reads an image input via the image sensor 205. The photographing device 101 determines whether the read image includes, for example, a two-dimensional code 602 (S804). If the read image includes the two-dimensional code 602 (YES in S804), the photographing device 101 analyzes the two-dimensional code 602 (S805). For example, if the two-dimensional code 602 is a QR code and the photographing device 101 has a QR code reader function, the photographing device 101 can extract information included in the QR code detected by reading the image by analyzing it using the QR code reader function. On the other hand, if the two-dimensional code 602 is not included in the read image (NO in S804), the photographing device 101 may display an error (S811). For example, the photographing device 101 may display on the LCD 208 that the two-dimensional code 602 was not detected.

[0035] The image capturing apparatus 101 determines whether the analysis result of the two-dimensional code 602 includes a URI indicating an access destination for acquiring the setting information (S806). For example, if the image capturing apparatus 101 detects a QR code by reading an image, it may extract information such as a URI included in the QR code, output the acquired information such as a URI to the LCD 208, provide it to the user, and request user input. Upon receiving user input indicating that the URI should be accessed, the image capturing apparatus 101 may continue processing, assuming that the URI is an access destination for acquiring the setting information. Note that if the image capturing apparatus 101 detects a QR code by reading an image and extracts information included in the QR code, it may access the acquired URI without waiting for user input. This eliminates the need for user operation. On the other hand, if the two-dimensional code 602 does not include information such as a URI (NO in S806), the image capturing apparatus 101 may display an error message (S811). For example, the image capturing device 101 may display on the LCD 208 that a valid URI was not extracted from the two-dimensional code 602. Note that the image capturing device 101 may continue to detect and analyze the two-dimensional code 602 and provide the extracted information to the user until the operating mode is switched. In this case, an error message may not be displayed.

[0036] The image capturing device 101 may request the information processing device 111 to provide the setting information via the identified URI (S807). At this time, the image capturing device 101 may provide the information processing device 111 with information that identifies the model of the image capturing device 101 and information that identifies the image 601. For example, the image capturing device 101 may provide the information processing device 111 with information that can identify the model of the image capturing device 101, such as the serial number or model number of the image capturing device 101. Information that can identify the model of the image capturing device 101 may be stored in the storage unit 204 of the image capturing device 101. Furthermore, if the read two-dimensional code 602 contains information that can identify the image 601, the image capturing device 101 may provide that information to the information processing device 111. Note that if a different URI for acquiring setting information is assigned to each image 601, when the image capturing device 101 accesses the URI, the information processing device 111 may identify the image 601 based on the request received from the access destination. For example, the information processing device 111 has a correspondence table between images 601 and URIs in advance, and can identify the URI used for access from the image capturing device 101 to identify the image 601 associated with that URI.

[0037] When the image capturing apparatus 101 receives setting information from the information processing device 111 with which it communicates via the accessed URI (YES in S808), it configures its own device using the setting information (S809). Before configuring the settings, the image capturing apparatus 101 may confirm with the user whether or not to configure the settings. In this case, the image capturing apparatus 101 may configure its own device based on receiving input from the user to configure the settings using the setting information. On the other hand, if the image capturing apparatus 101 does not receive input from the user to configure the settings using the setting information, it may terminate the processing without configuring the settings using the setting information. Furthermore, when the image capturing apparatus 101 does not receive setting information from the information processing device 111 with which it communicates via the accessed URI (NO in S808), it may display an error on the LCD 208.

[0038] Note that, in the above description, an example has been given in which the photographing device 101 identifies a predetermined URI for acquiring setting information by reading the two-dimensional code 602; however, the method by which the photographing device 101 identifies a predetermined URI is not limited to this. For example, the photographing device 101 may identify a predetermined URI by reading a one-dimensional code or by character recognition. Alternatively, the photographing device 101 may identify a URI by a user directly inputting the URI via the input unit 202. Furthermore, the photographing device 101 may acquire a URI using close proximity wireless communication. For example, URI information may be communicated between the photographing device 101 and the printed matter 141 by bringing the photographing device 101 close enough to the printed matter 141 to communicate via close proximity wireless communication. The close proximity wireless communication may be Near Field Communication (NFC). Alternatively, the close proximity wireless communication may be a technology other than NFC, such as, but not limited to, Bluetooth (registered trademark), Zigbee, a wireless tag, or the like. As a method for the image capturing device 101 to identify an access destination for acquiring setting information, any method that allows reading from a printed material using a means possessed by the image capturing device 101 can be used.

[0039] FIG. 9 shows an example of a processing flow executed by the information processing device 111 of this embodiment when a request for provision of setting information is received from the image capturing device 101. First, the information processing device 111 waits for a request for provision of setting information from the image capturing device 101 (NO in S901 and S902). When the information processing device 111 receives a request (YES in S902), it identifies the model of the image capturing device 101 that made the request and the image 601 (S903). For example, the information processing device 111 may identify the model of the image capturing device 101 based on information included in the request that can identify the model of the image capturing device 101. The information processing device 111 may also identify the image 601 based on information included in the request that can identify the image 601. Note that if different access destinations for acquiring setting information are assigned to each of the images 601 and models, or a combination thereof, the information processing device 111 may identify the image 601 and model by identifying the access destination used by the image capturing device 101.

[0040] The information processing device 111 determines whether or not the information processing device 111 has setting information corresponding to the identified combination of image 601 and model (S904). For example, if the information processing device 111 stores, in the storage unit 204, combinations of image 601 and model and setting information in association with each other, the information processing device 111 can identify the corresponding setting information by searching for the setting information based on the combination of image 601 and model. At this time, if setting information corresponding to the identified combination of image 601 and model is not identified, the information processing device 111 can determine that the information processing device 111 does not have setting information corresponding to the combination of image 601 and model.

[0041] If the information processing device 111 has setting information corresponding to the identified combination of image 601 and model (YES in S904), it transmits the setting information to the image capturing device 101 (S905). On the other hand, if the information processing device 111 does not have setting information corresponding to the identified combination of image 601 and model (NO in S904), it can notify the image capturing device 101 of an error (S906).

[0042] FIG. 10(a) shows an example of a URI acquired when the image capturing device 101 reads a two-dimensional code 602. For example, the URI may have a first portion that is common to each image 601 and a second portion that is different for each image 601. For example, the first portion may be "https: / / xxx.xxx / setting" (1001) in FIG. 10(a). The second portion may be "bar_code_id" (1002) in FIG. 10(b). Since the second portion differs depending on the image 601, the setting information corresponding to the image 601 can be uniquely identified in the information processing device 111. The second portion may be called an image capturing setting indicator.

[0043] FIG. 10B shows an example of a message used when the image capturing apparatus 101 requests the information processing device 111 to provide setting information. While FIG. 10B shows an example of using an HTTP request message in Multipart / form-data format, the format of the message used when the image capturing apparatus 101 requests the information processing device 111 to provide setting information is not limited to this. The example of FIG. 10B shows an example in which information identifying the model of the image capturing apparatus 101, "Model 1" (1003), is notified as the value of "model_name." The image capturing apparatus 101 can use this information to notify the information processing device 111 of its own model. By acquiring this information, the information processing device 111 can recognize the model of the image capturing apparatus 101 making the request. Note that this example shows an example in which information capable of identifying the model of the image capturing apparatus 101 is notified using the body portion of the message, but this information may also be notified using the header portion of the message. Furthermore, the information capable of identifying the model may be a model name or identification information that uniquely identifies the model. Identification information that uniquely identifies the model may be called a model identifier. The image capturing device 101 may use any message format or any expression method to notify the information processing device 111 of the model of the image capturing device 101 .

[0044] FIG. 11 shows an example of setting information stored in the information processing device 111. In the example of FIG. 11, a single predetermined image 601 is stored with different setting values ​​associated with each of a plurality of setting items for each model. The setting items of the setting information stored in the information processing device 111 may include shutter speed, aperture, ISO sensitivity, contrast, focal length, etc. The setting values ​​of each setting item may be the same or different for each model. For example, in FIG. 11, the setting values ​​of the shutter speed and focal length are the same for the first to Nth models. On the other hand, the setting values ​​of the ISO sensitivity and contrast are different for the first to Nth models. Furthermore, the setting value of the aperture is the same for the first model and the Nth model, but is different from that for the second model. The setting information stored in the information processing device 111 may include setting items other than those mentioned above, and may not include some or all of these setting items. The configurable setting items and configurable setting values ​​may differ for each model. The setting information stored in the information processing device 111 may include setting values ​​for any setting items that can be set for the imaging device to capture images. The information processing device 111 may accept changes or additions to the setting information. When accepting changes or additions to the setting information, the information processing device 111 updates the setting information stored therein using the accepted setting information. For example, when the information processing device 111 accepts setting information for a new model, it may add an area to the table for storing setting information associated with the model and store setting values ​​corresponding to each setting item. Furthermore, when the information processing device 111 wants to keep the setting values ​​for a specific model or a specific setting item private, it may delete the setting values ​​for the model or setting item that it wants to keep private from the table. Note that the information processing device 111 may retain the setting values ​​for the model or setting item that it wants to keep private in the table, but may not provide those setting values ​​in response to a request. Furthermore, when it accepts a request for setting information for a model not stored in the table, the information processing device 111 may notify the requester of an error or may provide the setting information for the model registered as default.For setting items that exist in the model notified by the request but do not exist in the model registered as the default, the default setting value set in that model may be used. Note that the information processing device 111 may store the above setting information internally, or may obtain and provide setting information stored in an external storage device in response to a request.

[0045] (Variation) In the above example, the image capturing device 101 reads a two-dimensional code 602 included in the printed matter 141 to obtain a URI for accessing the information processing device 111. Information for obtaining the setting information included in the printed matter 141 is not limited to a two-dimensional code and may be indicated by other methods. For example, information for obtaining the setting information may be embedded in the image 601 as a digital watermark. In this case, the image capturing device 101 may be unable to read this information. If the image capturing device 101 is unable to obtain the information indicated by the digital watermark from the image 601, the image capturing device 101 may be unable to identify the access destination for obtaining the setting information. Therefore, in this modification, instead of the image capturing device 101, a terminal device 1201 reads information embedded in the image 601 included in the printed matter 141 to provide the image capturing device 101 with information for obtaining the setting information. FIG. 12 shows an example of an information processing system used in the description of this modification. In FIG. 12, the same components as those in FIG. 1 are designated by the same reference numerals, and their description will be omitted. 12 can be configured by adding a terminal device 1201 to the configuration of the information processing system in Fig. 1. The terminal device 1201 is connected to the network 121 and is capable of communicating with the information processing device 111.

[0046] The terminal device 1201 provides information related to setting information to the image capturing device 101. For example, the terminal device 1201 may be a smartphone with a camera function. The terminal device 1201 is not limited to this and may be any device with a camera function, such as a mobile phone with a camera function, a tablet with a camera function, or a personal computer (PC) with a camera function. The hardware configuration of the terminal device 1201 may be the same as that of the image capturing device 101 shown in FIG. 2. That is, the terminal device 1201 may have a control unit 201, an input unit 202, an output unit 203, a storage unit 204, an image sensor 205, a communication control unit 206, a GPS 207, and an LCD 208.

[0047] FIG. 13 shows the functional configuration of the terminal device 1201. The terminal device 1201 may be configured with an information identification unit 1301, an information acquisition unit 1302, and an information provision unit 1303. The information identification unit 1301 identifies first information by reading a predetermined printed matter 141. For example, the first information may be information indicating an access destination for acquiring setting information. The first information may also be information capable of identifying the image 601. The information acquisition unit 1302 acquires second information based on the first information identified by the information identification unit 1302. The second information may be information that enables the image capture device 101 to acquire setting information. For example, the second information may be information indicating an access destination for acquiring setting information. The second information may also be the setting information itself. The information provision unit 1303 provides the second information to the image capture device 101. For example, the information providing unit 1303 can provide the second information by displaying the second information on the LCD 208 of the terminal device 1201. Furthermore, the information providing unit 1303 can provide the second information to the image capturing device 101 by communicating with the image capturing device 101 via the communication control unit 206.

[0048] The operation of the terminal device 1201 will be described. FIGS. 14(a) and 14(b) show an example of the operation of the terminal device 1201. FIG. 14(a) shows an example of a display on the terminal device 1201 when the terminal device 1201 reads specific information (first information) from the image 601. FIG. 14(b) shows an example of a display of second information displayed on the screen of the terminal device 1201 based on the first information read by the terminal device 1201 from the image 601. The first information may be, for example, information indicated by a digital watermark embedded in the image 601. The second information may be, for example, a two-dimensional code that can be read by the image capturing device 101. This operation may be initiated, for example, by the launch of a specific application installed in the terminal device 1201. The specific application may be, for example, an application having a function for assisting in the setting of the image capturing device 101. When the terminal device 1201 starts its operation, it reads an image input via its own image sensor 205. The input image may be displayed in area 1401 on the screen. The terminal device 1201 analyzes the input image to determine whether specific first information is embedded therein. The first information may be, for example, information indicating information on an access destination for acquiring setting information. The first information is not limited to this, and may be, for example, information for identifying the image 601. For example, the terminal device 1201 may acquire the first information embedded in the image 601 by performing image processing or image analysis, such as a predetermined filtering process or a predetermined pattern matching process, on the scanned image. The image processing method or image analysis method used by the terminal device 1201 to acquire the first information from the image is not limited to these, and any image processing method or image analysis method may be used.

[0049] When the terminal device 1201 detects that first information is embedded in the image 601, it acquires second information based on the first information. For example, when the first information is information indicating an access destination for acquiring setting information, the terminal device 1201 may convert the first information into second information that can be read by the imaging device 101 and display the converted information on the screen. For example, the second information may be a two-dimensional code. For example, when the terminal device 1201 detects the first information, it may display, using the area 1402 on the screen, that the first information has been detected. For example, the terminal device 1201 may notify the user that the first information has been detected by displaying text such as "Display two-dimensional code" in the area 1402. Note that the method of notifying the user that the terminal device 1201 has detected the first information is not limited to this; for example, the terminal device 1201 may display, in the area 1401, that the first information has been detected. In these cases, the area 1402 may be used as an area for accepting input from the user. For example, the terminal device 1201 may acquire second information based on a user input in response to a display indicating that the first information has been detected, and display the acquired second information on the screen. For example, the second information may be displayed in an area 1403 in FIG. 14(b). The second information displayed in the area 1403 is read by the image capturing device 101, which enables the image capturing device 101 to acquire setting information from the information processing device 111.

[0050] The terminal device 1201 may acquire the second information from another device. For example, if the first information is information indicating an access destination for acquiring the setting information, the terminal device 1201 may access the access destination indicated by the first information and acquire the second information from the information processing device 111. In this case, for example, information indicating the model of the image capturing device 101 to be configured may be set in advance in the terminal device 1201. Then, the terminal device 1201 may notify the information processing device 111 of the scanned image 601 and information indicating the model of the image capturing device 101, and acquire the second information from the information processing device 111. When the information processing device 111 is requested by the terminal device 1201 to provide the second information, the information processing device 111 generates second information corresponding to the combination of the model of the image capturing device 101 to be configured and the image 601, and notifies the terminal device 1201 of the second information. The second information may be information indicating an access destination to be accessed by the image capturing device 101 to acquire the setting information. With this configuration, even if the terminal device 1201 does not have a function for generating second information, it can provide the image capturing device 101 with information indicating an access destination for acquiring setting information. Note that the information processing device 111 may generate and store in advance second information indicating an access destination for each combination of model and image 601. With this configuration, the information processing device 111 does not need to generate second information every time it receives a request. The device that the terminal device 1201 accesses to acquire the second information does not have to be the information processing device 111. For example, the terminal device 1201 may acquire the second information from another information processing device.

[0051] Note that the information that the terminal device 1201 acquires from another device may be the setting information itself. For example, when the terminal device 1201 acquires the first information, it may notify the information processing device 111 of information capable of identifying the combination of the model of the image capturing device 101 and the image 601, as described above, and acquire setting information corresponding to that combination from the information processing device 111. In this case, the terminal device 1201 may use the acquired setting information to generate information that can be read by the image capturing device 101 as second information and display it on the screen. The image capturing device 101 may acquire the setting information by reading the second information displayed on the screen of the terminal device 1201. The terminal device 1201 may also provide the setting information to the image capturing device 101 using another method. For example, if the terminal device 1201 can communicate with the image capturing device 101 using a communication method such as NFC or Bluetooth, the terminal device 1201 may provide the setting information to the image capturing device 101 using that communication method.

[0052] If the access destination of the information processing device 111 for acquiring the setting information is known in the terminal device 1201, the terminal device 1201 can acquire the second information or the setting information itself using the access destination. For example, if an access destination for acquiring the setting information is set in advance in an application running on the terminal device 1201 and identification information for identifying the image 601 is acquired as the first information, the terminal device 1201 can notify the access destination of the identification information. In this way, if a common access destination for acquiring the setting information is provided and the corresponding second information or setting information can be acquired by notifying the identification information of the image 601 and information that can identify the model, the amount of information to be embedded in the image 601 can be reduced.

[0053] On the other hand, the terminal device 1201 may locally generate second information based on the first information. For example, if the first information includes information indicating an access destination for obtaining the setting information, the terminal device 1201 may use this first information to generate second information readable by the image capturing device 101 and display it on the screen. In this case, the second information may be information indicating an access destination for obtaining the setting information. With this configuration, the terminal device 1201 can provide the second information to the image capturing device 101 without communicating with another device such as the information processing device 111.

[0054] In the above description, the terminal device 1201 has both the function of reading the first information from the image 601 and the function of providing the second information to the imaging device 101, but a configuration in which multiple different devices have each of the functions may also be used. For example, a reader device may read the first information from the image 601, and a device having a display means, such as a PC, different from the reader device may receive the first information from the reader device, and obtain the second information from the first information and display it on the display means.

[0055] FIG. 15 shows an example of a sequence of messages exchanged between the terminal device 1201, the photographing device 101, and the information processing device 111. In this example, the first information includes information indicating an access destination for acquiring setting information, and the terminal device 1201 accesses the access destination to acquire the second information and displays it on the screen. The second information is information readable by the photographing device 101 indicating an access destination for acquiring setting information. This sequence is started, for example, by starting a specific application installed in the terminal device 1201. When the terminal device 1201 starts operation, it reads an image input via its own image sensor 205. For example, the terminal device 1201 reads the image 601 on the printed matter 141 and determines whether first information is embedded therein. When the terminal device 1201 detects the first information, it reads the first information (F1501). The terminal device 1201 displays on the LCD 208 that the first information has been detected, and may receive a user input as to whether or not to display the second information. For example, the terminal device 1201 may access the information processing device 111 based on receiving a user input indicating that the second information should be displayed.

[0056] The terminal device 1201 accesses the information processing device 111 via the access destination identified based on the first information. For example, the terminal device 1201 can access the information processing device 111 by accessing the URI indicated by the first information. When accessing the information processing device 111, the terminal device 1201 can notify the information processing device of information identifying the model of the image capturing device 101 and the image 601, and request the second information (F1502). Based on receiving a request for providing the second information from the terminal device 1201, the information processing device 111 can provide the terminal device 1201 with the second information corresponding to the notified model and image 601 (F1503). The terminal device 1201 displays the acquired second information on the screen (F1504).

[0057] The photographing device 101 reads the second information displayed on the screen of the terminal device 1201 using its own image sensor 205 (F1505). Reading of the second information by the photographing device 101 can be executed in the same manner as reading of the two-dimensional code 602 in F701 in FIG. 7. The photographing device 101 also accesses the information processing device 111 using the read second information. The setting operation of the photographing device 101 based on messages exchanged between the photographing device 101 and the information processing device 111 is the same as the processing in F702 to F704 in FIG. 7, and therefore description thereof will be omitted.

[0058] As described above, according to this embodiment, the photographing device 101 identifies an access destination for acquiring predetermined setting information based on reading a predetermined printed material containing a predetermined image, and acquires the predetermined setting information by communicating with an information processing device via the access destination. The photographing device 101 then configures its own device using the acquired setting information. With this configuration, even if the setting information provided to the photographing device is added or changed, the setting information set in the photographing device 101 can be updated by adding or changing the setting information stored in the information processing device. This makes it possible to provide setting information corresponding to a new model without having to reprint printed materials, even when a new model is manufactured or sold. Furthermore, the terminal device 1201 can read the predetermined printed material instead of the photographing device 101 and provide information for the photographing device 101 to acquire the setting information. With this configuration, it is possible to provide setting information even if a specific model of the photographing device 101 cannot read information contained in the predetermined printed material. This makes it possible for the information processing device to provide setting information for a wider range of models. Furthermore, by providing the setting information via the terminal device 1201, it is possible to provide the setting information using the communication function or the like that the image capturing device 101 has.

[0059] The present invention can also be realized by supplying a program that realizes one or more functions of the above-described embodiments to a system or device via a network or a storage medium, and having one or more processors in the computer of the system or device read and execute the program. It can also be realized by a circuit (e.g., ASIC) that realizes one or more functions.
