  The imaging apparatus according to the first embodiment will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a digital camera 2 according to the embodiment. The digital camera 2 includes a CPU 4 that comprehensively controls each unit of the digital camera 2. The CPU 4 includes an operation unit 6 including a power switch and a shutter button (not shown), a communication unit 8 that communicates with a server (not shown) via a network, and short-range wireless communication such as Wi-Fi (registered trademark). A short-range communication unit 10 that communicates with an external device, an LCD display unit 12 that displays an image, a touch panel 14 that detects a position where a finger or the like touches on the LCD display unit 12, an image of subject light is generated and an imaging signal is generated. Image sensor 16, image storage unit 18 that temporarily stores image data generated by the imaging signal output from image sensor 16, information storage unit 20 that stores external device identification information such as a MAC address, and image data Is connected to a memory card slot 24 into which a memory card 22 is stored.

  Next, a registration process for registering identification information of an external device in the digital camera 2 according to the first embodiment will be described. Hereinafter, a case where the user A who owns the digital camera 2 and the smartphone 26 a illustrated in FIG. 2 registers the identification information of the smartphone 26 a in the digital camera 2 will be described as an example. First, when an operation for linking the digital camera 2 to the smartphone 26a is performed by the user A, a predetermined signal is transmitted and received between the digital camera 2 and the smartphone 26a via the short-range communication unit 10, and the digital camera 2 and the short-range wireless communication are established between the smartphone 26a.

  When the short-range wireless communication is established, the CPU 4 acquires the MAC address “SF-A” that is identification information of the smartphone 26 a from the smartphone 26 a and stores the MAC address “SF-A” in the information storage unit 20. Thereby, the registration process of the MAC address “SF-A” to the digital camera 2 is completed.

  Next, with reference to a flowchart shown in FIG. 3, a transfer process when image data captured using the digital camera 2 according to the first embodiment is transferred to an external device will be described. First, when a subject is photographed by the image sensor 16 (step S1), the CPU 4 temporarily stores image data of the photographed image in the image storage unit 18.

  Next, the CPU 4 reads out the image data from the image storage unit 18, reads out the MAC address “SF-A” from the information storage unit 20, adds the MAC address “SF-A” to the image data, and stores it in the memory card 22. Store (step S2).

  After shooting, when the digital camera 2 is linked to the external device and short-distance wireless communication is established between the digital camera 2 and the external device (step S3), the CPU 4 passes through the short-range communication unit 10. The identification information of the external device is acquired (step S4). For example, as illustrated in FIG. 4, when the digital camera 2 is linked to the smartphone 26a, the CPU 4 acquires the MAC address “SF-A” from the smartphone 26a. On the other hand, when the digital camera 2 is linked to the smartphone 26b owned by the user B, the CPU 4 acquires the MAC address “SF-B” that is identification information of the smartphone 26b from the smartphone 26b.

  Next, when an operation for transferring the image data to the external device (for example, an operation for copying the image data to the external device by drag and drop, etc.) is performed, the CPU 4 determines the MAC address added to the image data and the transfer destination. It is determined whether or not the MAC address of the external device matches (step S5). When the MAC address added to the image data matches the MAC address of the transfer destination external device (step S5: Yes), the CPU 4 permits the output of the image data from the digital camera 2 (step S6). For example, when the user A performs an operation of transferring image data of an image captured by the digital camera 2 to the smartphone 26a, the MAC address “SF-A” added to the image data is the MAC address “of the smartphone 26a” Since it matches “SF-A”, transfer of image data is permitted (see FIG. 4). In this case, the CPU 4 transfers the image data to the smartphone 26a (Step S7).

  On the other hand, when the MAC address added to the image data does not match the MAC address of the transfer destination smartphone 26a (step S5: No), the CPU 4 prohibits the output of the image data from the digital camera 2 (step S8). ). For example, it is assumed that the user B illegally obtains the digital camera 2 and takes an image, and performs an operation of transferring image data of the taken image to the smartphone 26b. In this case, since the MAC address “SF-A” added to the image data is different from the MAC address “SF-B” of the smartphone 26b, transfer of the image data is prohibited (see FIG. 4). The CPU 4 displays a message such as “This image cannot be copied” on the LCD display unit 12 (step S9).

  According to the invention according to the first embodiment, image data cannot be output to an external device other than the smartphone 26a in which the MAC address is registered in advance, so that the image data cannot be used illegally. A highly-capable imaging device and system can be provided.

  In the first embodiment described above, the imaging device is not necessarily the digital camera 2, and may be a smartphone, a mobile phone, a tablet terminal, or the like. The external device is not necessarily a smartphone, and may be a digital camera, a mobile phone, a tablet terminal, a personal computer, or the like.

  In the first embodiment described above, communication with an external device is performed via the short-range communication unit 10, but wired communication means may be used. For example, the digital camera 2 may have a USB terminal and communicate with an external device via a USB cable.

  Next, a server according to the second embodiment will be described. The invention according to the second embodiment is such that, in the first embodiment, whether or not output of image data is permitted is determined on the server side. Here, as shown in FIG. 1, the digital camera 202 according to the second embodiment has the same configuration as the digital camera 2 according to the first embodiment. Therefore, in the second embodiment, portions different from the first embodiment will be described in detail, and descriptions of overlapping portions will be omitted as appropriate.

  FIG. 5 is a block diagram illustrating a configuration of the server 32 according to the embodiment. The server 32 is a server that provides a predetermined social networking service site (hereinafter referred to as an SNS site), and includes a CPU 34 that controls each part of the server 32 in an integrated manner. Connected to the CPU 34 are a communication unit 38 that communicates with the digital camera 202 via a network, and an image storage unit 40 that stores image data of images uploaded from the digital camera 202.

  Next, registration processing for registering identification information in the digital camera 202 according to the second embodiment will be described by taking as an example a case where the user C registers the ID and password of his / her page on the SNS site. First, as shown in FIG. 6, the user C accesses the SNS site from the digital camera 202. Next, when the user C inputs the ID “CCCC” and the password “ssss” by operating the touch panel 14 and logs in to the page “SNS-C” that is the page of the user C, the CPU 4 inputs the input ID “CCCC”. And the password “ssss” are stored in the information storage unit 20. Thereby, the registration process of the ID “CCCC” and the password “ssss” to the digital camera 2 is completed.

  Next, with reference to a flowchart shown in FIG. 7, a transfer process in the case of transferring image data captured using the digital camera 202 according to the second embodiment will be described. First, when a subject is photographed by the image sensor 16, the CPU 4 temporarily stores image data of the photographed image in the image storage unit 18.

  Next, the CPU 4 reads the image data from the image storage unit 18, reads the ID “CCCC” and the password “ssss” from the information storage unit 20, adds the ID and password to the image data, and stores them in the memory card 22. To do.

  After the image is taken, the SNS site is accessed from the digital camera 202, and when an ID and password are input when logging in to a predetermined page, the CPU 34 of the server 32 recognizes the input ID and password. (Step S21). For example, as illustrated in FIG. 8, when the user C logs in to the page “SNS-C” from the digital camera 202, the CPU 34 recognizes the ID “CCCC” and the password “ssss” input at the time of login. On the other hand, when the user D logs in to the “SNS-D” that is the page of the user D from the digital camera 202, the CPU 34 recognizes the ID “DDDD” and the password “tttt” of the page of the user D input at the time of login. To do.

  Next, when an operation of uploading an image to a page on the SNS site is performed, the CPU 4 determines whether or not the ID and password recognized at the time of login match the ID and password added to the image data ( Step S22). When the ID and password recognized at the time of login match the ID and password added to the image data (step S22: Yes), the CPU 34 permits the reception of the image data from the digital camera 202 (step S23). For example, when the user C performs an operation of uploading an image captured by the digital camera 202 to the page “SNS-C”, the ID “CCCC” and the password “ssss” recognized at the time of login are added to the image data. Since the ID “CCCC” and the password “ssss” match, the image upload is permitted (see FIG. 8). In this case, the CPU 34 performs a process of uploading an image based on the image data to the page “SNS-C” (step 24).

  On the other hand, when the ID and password recognized at the time of login do not match the ID and password added to the image data (step S22: No), the CPU 34 prohibits reception of image data from the digital camera 202 (step S25). . For example, it is assumed that the user D illegally obtains the digital camera 202 and captures an image and uploads the captured image to the page “SNS-D” of the user D. In this case, since the ID “DDDD” and the password “tttt” recognized at the time of login are different from the ID “CCCC” and the password “ssss” added to the image data, image upload is prohibited (see FIG. 8). The CPU 34 displays a message such as “This image cannot be uploaded” on the LCD display unit 12 (step S26).

  According to the invention according to the second embodiment, if the ID and password added to the image data do not match the login ID and password, the image cannot be uploaded. It is possible to provide a highly secure server and system that will not be disclosed.

  In the second embodiment described above, the imaging device is not necessarily the digital camera 202, and may be a smartphone, a mobile phone, a tablet terminal, or the like.

  Further, in the second embodiment described above, as in the first embodiment, the digital camera 202 may determine whether image data output is permitted or not. For example, when shooting with the digital camera 202 is performed, the CPU 4 adds a previously registered ID and password to the image data. After shooting, when the digital camera 2 is used to log in to a page on the SNS site and an operation for uploading an image based on the image data to the page on the SNS site is performed, the CPU 4 is added to the image data. It is determined whether or not the existing ID and password match the ID and password input at the time of login. When the ID and password added to the image data match the ID and password input at the time of login, that is, when an image taken by the user C is uploaded to the page “SNS-C”, the CPU 4 2 is permitted to output the image data from the image data, and an image based on the image data is uploaded to the user's page.

  On the other hand, when the ID and password added to the image data do not match the ID and password input at the time of login, for example, when the user D uploads an image taken by the user C to the page “SNS-C” The CPU 4 prohibits the output of image data from the digital camera 2.

  Next, a system according to a third embodiment will be described. The invention according to the third embodiment is such that, in the second embodiment, the server receives image data from a digital camera via a smartphone. In addition, information necessary for determining whether to receive image data on the server side is added to the image data by the smartphone. Here, as shown in FIG. 1, a digital camera 204 according to the third embodiment has the same configuration as the digital camera 202 according to the second embodiment, and a server according to the third embodiment. 232 has the same configuration as the server 232 according to the second embodiment. Therefore, in the third embodiment, portions different from those of the second embodiment will be described in detail, and descriptions of overlapping portions will be omitted as appropriate.

  FIG. 9 is a block diagram illustrating a configuration of the smartphone 56a according to the embodiment. The smartphone 56a includes a CPU 60 that comprehensively controls each unit of the smartphone 56a. The CPU 60 includes an operation unit 66 including a power switch (not shown) and the like, a communication unit 68 that communicates with a server (not shown) via a network (not shown), and short-range wireless communication. , A short-range communication unit 70 that communicates with the digital camera 204, an LCD display unit 72 that displays an image, a touch panel 74 that detects a position where a finger or the like touches on the LCD display unit 72, an image of a subject light, and an imaging signal An image sensor 76 to be generated, an image storage unit 78 for temporarily storing image data, an information storage unit 80 for storing identification information of the smartphone 56a, and a memory card slot 84 for mounting a memory card 82 for storing image data are connected. Has been.

  Next, regarding the registration process for registering the identification information of the external device in the digital camera 204 according to the third embodiment, the user E who owns the digital camera 204 and the smartphone 56a shown in FIG. A case where “SF-E” is registered in the digital camera 204 will be described as an example. First, when near field communication is established between the digital camera 2 and the smartphone 56 a, the CPU 4 acquires the MAC address “SF-E” from the smartphone 56 a and stores it in the information storage unit 20. Thereby, the registration process of the MAC address “SF-E” to the digital camera 204 is completed.

  Next, with reference to a flowchart shown in FIG. 11, a transfer process when image data shot using the digital camera 204 according to the third embodiment is transferred to an external device will be described. First, when the subject is photographed by the image sensor 16 (step S41), the CPU 4 temporarily stores the image data of the photographed image in the image storage unit 18.

  Next, the CPU 4 reads out the image data from the image storage unit 18, reads out the MAC address “SF-E” from the information storage unit 20, adds the MAC address “SF-E” to the image data, and stores it in the memory card 22. (Step S42).

  When an operation for transferring image data to the smartphone 56a (for example, an operation for copying image data to the smartphone 56a by drag and drop, etc.) is performed after shooting (step S43), the CPU 60 of the smartphone 56a Data is received (step S51). Next, the CPU 60 determines whether or not the MAC address added to the image data matches the MAC address of the smartphone 56a (step S52). When the MAC address added to the image data matches the MAC address of the smartphone 56a (step S52: Yes), the CPU 60 adds permission information for permitting image upload to the SNS site to the image data (step S52). S53), and stored in the image storage unit 78. For example, when the user E performs an operation of transferring image data of an image captured using the digital camera 204 to the smartphone 56a, the MAC address “SF-E” added to the image data is the MAC of the smartphone 26a. Since it matches the address “SF-E”, permission information is added to the image data (see FIG. 12).

  On the other hand, when the MAC address added to the image data does not match the MAC address of the smartphone 56a (step S52: No), the CPU 60 adds the image data to the image storage unit 78 without adding the permission information to the image data. To remember. For example, it is assumed that the user F illegally obtains the digital camera 204 and captures an image, and transfers the image data of the captured image to the smartphone 56b owned by the user F. In this case, since the MAC address “SF-E” added to the image data is different from the MAC address of the smartphone 56b, permission information is not added to the image data (see FIG. 12). Further, when the user F captures an image with a digital camera owned by the user F and transfers the image data of the captured image to the smartphone 56a, the MAC address added to the image data is the MAC address “SF−” of the smartphone 26a. Since it is different from “E”, permission information is not added to the image data.

  Next, when an operation for uploading an image based on the image data to the SNS site is performed, the image data is transferred from the smartphone to the SNS site (step S54). When receiving the image data (step S61), the CPU 34 of the server 232 determines whether permission information is added to the image data (step S62). When the permission information is added to the image data (step S62: Yes), the CPU 34 permits the reception of the image data from the digital camera 204 (step S63). In this case, the CPU 34 performs a process of uploading the image to the SNS site (step S64).

  On the other hand, when the permission information is not added to the image data (step S62: No), the CPU 34 prohibits the reception of the image data from the digital camera 204 (step S65). In this case, the CPU 34 displays a message such as “This image cannot be copied” on the LCD display unit 72 (step S66).

  According to the invention according to the third embodiment, since the user cannot upload an image taken with the digital camera through the SNS site without using a smartphone that is paired with the digital camera, the image is illegal. It is possible to provide a highly secure system that is not disclosed.

  In the third embodiment described above, the imaging device is not necessarily the digital camera 204, and may be a smartphone, a mobile phone, a tablet terminal, or the like. The device that communicates with the imaging device is not necessarily the smartphone 56a, but may be a digital camera, a mobile phone, a tablet terminal, a personal computer, or the like.

  In the above-described third embodiment, wired communication means may be used for communication between the smartphone 204 and the smartphone 56a. For example, the digital camera 204 may have a USB terminal and communicate with the smartphone 56a via a USB cable.

  Next, an imaging device according to a fourth embodiment will be described. The invention according to the fourth embodiment is such that, in the first embodiment, image data cannot be output unless it is further connected to an external device via a specific communication line. Here, as shown in FIG. 1, a digital camera 206 according to the fourth embodiment has the same configuration as the digital camera 2 according to the first embodiment. Therefore, in the fourth embodiment, portions different from the first embodiment will be described in detail, and descriptions of overlapping portions will be omitted as appropriate.

  FIG. 13 is a diagram showing a digital camera 206 and a personal computer 92 according to the fourth embodiment. Here, the digital camera 206 can perform short-range communication with the personal computer 92 via either the communication line “SSIDα” or the communication line “SSIDβ”.

  Of the two, the communication line “SSIDα” is a secret communication line that is not open to third parties. For this reason, when communicating with the personal computer 92 via the communication line “SSIDα”, a special operation such as inputting the password of the communication line “SSIDα” via a predetermined input screen is required. On the other hand, the communication line “SSIDβ” is a communication line that is disclosed to a third party. When an operation for linking the digital camera 206 to the personal computer 92 is performed, the digital camera is not limited unless the above-described special operation is performed. 206 is connected to the personal computer 92 via the communication line “SSIDβ”.

  Here, the case where the communication line “SSIDα” is a secret communication line and the communication line “SSIDβ” is a publicly disclosed communication line will be described as an example. The user G who is the owner of the digital camera 206 and the personal computer 92 can arbitrarily set the communication line.

  Next, a registration process for registering identification information of an external device in the digital camera 206 according to the fourth embodiment will be described by taking as an example a case where the user G registers the identification information of the personal computer 92 in the digital camera 206.

  First, as shown in FIG. 13, when the digital camera 206 is connected to the personal computer 92 via the communication line “SSIDα” by the operation of the user G, the CPU 4 acquires the MAC address “1111” of the personal computer 92 from the personal computer 92. To do. Then, the MAC address “1111” and the communication line “SSIDα” are stored in the information storage unit 20. Thereby, the registration process of the MAC address “1111” and the communication line “SSIDα” to the digital camera 206 is completed.

  Next, with reference to a flowchart shown in FIG. 14, a transfer process in the case of transferring image data captured using the digital camera 206 according to the fourth embodiment to an external device will be described. First, when the subject is photographed by the image sensor 16 (step S81), the CPU 4 temporarily stores the image data of the photographed image in the image storage unit 18.

  Next, the CPU 4 reads out the image data from the image storage unit 18, reads out the MAC address “1111” from the information storage unit 20, adds the MAC address “1111” to the image data, and stores the image data in the memory card 22 (step). S82).

  After shooting, when the digital camera 206 is linked to an external device via any communication line and short-range wireless communication is established between the digital camera 206 and the external device (step S83), the CPU 4 The MAC address of the external device is acquired via the short-range communication unit 10 (step S84).

  Next, when an operation of transferring the image data to the external device (for example, an operation of copying the image data to the external device by drag and drop, etc.) is performed, the CPU 4 first determines that the digital camera 206 and the external device are the information storage unit. It is determined whether or not the connection is established via the communication line “SSIDα” stored in 20 (step S85).

  When the digital camera 206 is connected to the external device via the communication line “SSIDα” (step S85: Yes), the CPU 4 determines the MAC address added to the image data and the MAC address of the transfer destination external device. It is determined whether or not they match (step S86).

  When the MAC address added to the image data matches the MAC address of the transfer destination external device (step S86: Yes), the CPU 4 permits the output of the image data from the digital camera 206 (step S87). For example, as shown in FIG. 13, when the user G performs an operation of transferring image data of an image captured by the digital camera 206 to the personal computer 92 via the communication line “SSIDα”, the image is added to the image data. Since the existing MAC address “1111” matches the MAC address “1111” of the personal computer 92, transfer of image data is permitted. In this case, the CPU 4 transfers the image data to the personal computer 92 (step S88).

  On the other hand, when the digital camera 206 is not connected to the external device via the communication line “SSIDα” (step S85: No), the MAC address added to the image data and the MAC address of the transfer destination external device are If at least one of the conditions is not satisfied (step S86: No), the CPU 4 prohibits the output of image data from the digital camera 206 (step S89). For example, as shown in FIG. 15, it is assumed that wife G of user G connects digital camera 206 to personal computer 92 via communication line “SSIDβ” and performs an operation of transferring image data to personal computer 92. In this case, since the digital camera 206 is not connected to the personal computer 92 via the communication line “SSIDα”, transfer of image data is prohibited. Further, as shown in FIG. 15, the wife G of the user G connects the digital camera 206 to the personal computer 93 of the wife H via the communication line “SSIDα”, and the image data of the image captured by the user G with the digital camera 206 is displayed. Assume that an operation of transferring to the personal computer 93 is performed. In this case, since the MAC address “1111” added to the image data is different from the MAC address “2222” of the transfer destination external device, transfer of the image data is prohibited. The CPU 4 displays a message such as “This image cannot be copied” on the LCD display unit 12 (step S90).

  According to the invention according to the fourth embodiment, image data cannot be output from the imaging device except when the imaging device is connected to a specific external device via a specific communication line. It is possible to provide a highly safe imaging apparatus and system in which data is not illegally used.

  Note that in the above-described fourth embodiment, the imaging device is not necessarily the digital camera 206, and may be a smartphone, a mobile phone, a tablet terminal, or the like. The external device is not necessarily a personal computer, and may be a digital camera, a smartphone, a mobile phone, a tablet terminal, or the like.

  Hereinafter, a system according to a fifth embodiment will be described with reference to the drawings. 2.

Here, the personal information stored in the personal information storage unit 394 includes a profile posted on each user's page on the SNS site. In addition, the user can post the email address of the smartphone 306 on the profile.

  Next, processing of the image sharing system 302 according to the fifth embodiment will be described with reference to FIG. In the following, a case where the user J who is the owner of the digital camera 304 and the smartphone 306 uploads the captured image α taken by the digital camera 304 to an SNS site (not shown) will be described as an example.

  First, when the user J captures the captured image α using the digital camera 304, the CPU 330 of the digital camera 304 temporarily stores the image data of the captured image α in the image storage unit 344. Next, the CPU 330 reads out the image data of the captured image α from the image storage unit 344, and the information generation unit 346 generates image information “111010010” based on the image data of the captured image α (step S301).

  Next, the CPU 330 transmits the image information “111010010” to the smartphone 306 by the short-range communication unit 336 (step S302). When the smartphone 306 receives the image information “111010010” by the short-range communication unit 366, the smartphone 306 stores the received image information “111010010” in the information storage unit 376.

  Here, when the user J accesses the SNS site from the digital camera 304 and logs in to the page J1 (not shown) of the user J, the page J1 is displayed on the LCD display unit 338 of the digital camera 304. Note that login to the page J1 is easily performed without entering an ID, password, or the like.

  Next, when the user J performs an operation of uploading the captured image α to the page J1, for example, by operating the touch panel 340, the CPU 330 of the digital camera 304 uses the communication unit 334 to transmit the image data of the captured image α to the web server 308. (Step S303). The CPU 390 of the web server 308 receives the image data of the captured image α and uploads the captured image α to the page J1. Image data of the captured image α is stored in the image storage unit 396. At this point, the captured image α is not yet ready for browsing.

  Next, the CPU 390 reads out the image data of the photographed image α from the image storage unit 396 and generates image information “111010010” based on the image data (step S304). Next, the CPU 390 transmits the image information “111010010” to the smartphone 306 via the network 310 by the communication unit 392 (step S305). Here, the transmission process to the smartphone 306 is performed, for example, addressed to the email address of the smartphone 306 posted on the page J1.

  When the smartphone 306 receives the image information “111010010” from the web server 308 via the communication unit 364, the smartphone 306 searches the information storage unit 376, and image information that matches the received image information “111010010” is stored in the information storage unit 376. It is determined whether or not (step S306).

  When image information that matches the received image information “111010010” is stored in the information storage unit 376, the CPU 360 of the smartphone 306 determines that the captured image α should be disclosed. Then, public instruction information indicating that the photographed image α should be disclosed is generated, and the public instruction information is transmitted to the web server 308 by the communication unit 364 (step S307).

  On the other hand, when image information that matches the received image information “111010010” is not stored in the information storage unit 376, the CPU 360 determines that the captured image α should not be disclosed. Then, non-public instruction information for prohibiting the disclosure of the photographed image α is generated, and the non-public instruction information is transmitted to the web server 308 by the communication unit 364 (step S307).

  When the CPU 390 of the web server 308 receives the instruction information transmitted from the smartphone 306, the CPU 390 performs a disclosure process or a non-disclosure process for the captured image α based on the content of the received instruction information. That is, when the disclosure instruction information is received from the smartphone 306, the CPU 390 publishes the captured image α on the page J1. On the other hand, when the non-disclosure instruction information is received from the smartphone 306, the CPU 390 does not disclose the photographed image α on the page J1.

  According to the fifth embodiment, in order to determine whether the captured image α uploaded to page A by the smartphone 306 possessed by the user J as a pair with the digital camera 304 is public or private, It is possible to accurately prevent the photographed image α from being illegally photographed by the three parties and released on the SNS site.

  For example, it is assumed that a third party illegally obtains the digital camera 304, captures the captured image α, and uploads it to the page J1. Here, if the third party does not have the smartphone 306 at the time of shooting and the smartphone 306 and the digital camera 304 are not located within a range where short-range wireless communication is possible, as shown in FIG. 306 cannot receive the image information “111010010” from the digital camera 304. In this case, the CPU 360 of the smartphone 306 cannot detect image information that matches the image information “111010010” transmitted from the web server 308, and the captured image α is not disclosed on the page J1.

  Also, assume that the captured image α is illegally altered to the captured image α ′ by some means in the process of uploading to the page J1. In this case, as illustrated in FIG. 22, the image information “111010111” generated from the image data of the captured image α ′ in the web server 308 is the image information “111010010” generated from the image data of the captured image α in the digital camera 304. Does not match. Therefore, the CPU 360 of the smartphone 306 cannot detect image information that matches the image information “111010111” transmitted from the web server 308, and the captured image α is not disclosed on the page J1.

  In addition, according to the invention according to the fifth embodiment, since no input of an ID, a password, or the like is requested at the time of login, anyone can easily access the page J1, while collating image information with the smartphone 306. This makes it possible to strictly manage whether or not a photographed image can be disclosed.

  In the fifth embodiment described above, as shown in FIG. 23, when uploading the photographed image α to the page J1, the image information “111010010” may be transmitted to the web server 308 together. (Step S304 '). In this case, the web server 308 transfers the image information “111010010” received from the digital camera 304 to the smartphone 306.

  Upon receiving the image information “111010010” from the web server 308, the smartphone 306 determines whether image information that matches the received image information “111010010” is stored in the information storage unit 376. Then, based on the determination result, public instruction information or non-public instruction information is generated and transmitted to the web server 308. The web server 308 performs public processing or non-public processing of the captured image α according to the content of the instruction information received from the smartphone 306.

  As a result, even when the web server 308 does not have a function of generating image information from image data, the smartphone 306 can determine whether the photographed image α is disclosed or not based on the image information. It is possible to accurately prevent the captured image α from being illegally captured and disclosed on the SNS site.

  For example, when a third party takes a photographed image α and uploads it to the page J1, if the third party does not have the smartphone 306 at the time of photographing, the smartphone 306 is removed from the digital camera 304 as shown in FIG. The image information “111010010” cannot be received. Further, even if the smartphone 306 receives the image information “111010010” transferred from the digital camera 304 via the web server 308, the smartphone 306 cannot detect image information that matches the image information “111010010”. For this reason, the photographed image α is not disclosed on the page J1.

  In the fifth embodiment, the web server 308 can transmit the image information “111010010” to the smartphone 306 even when the e-mail address of the smartphone 306 is not posted on the page J1. Good. For example, the user J registers the email address of the smartphone 306 in the digital camera 304 in advance. When the captured image α is captured, the CPU 330 of the digital camera 304 associates the email address of the smartphone 306 with the image data of the captured image α.

  Next, when the captured image α is uploaded to the page J1 and the image information “111010010” is generated in the web server 308, the CPU 390 of the web server 308 sends an email of the smartphone 306 associated with the image data of the captured image α. Image information “111010010” is transmitted to the address.

  As shown in FIG. 23, when image information “111010010” is transmitted to the web server 308 together with the image data of the captured image α, the CPU 390 of the web server 308 is associated with the image data of the captured image α. The image information “111010010” is transferred to the e-mail address.

  In the fifth embodiment described above, the case where short-range wireless communication is performed between the digital camera 304 and the smartphone 306 has been described as an example. However, the digital camera 304 and the smartphone 306 are respectively connected to the USB. It may have a terminal and be connected via a USB cable.

  In the fifth embodiment described above, the imaging apparatus is not necessarily the digital camera 304, and may be a smartphone, a mobile phone, a tablet terminal, or the like. The communication device is not necessarily the smartphone 306, and may be a digital camera, a mobile phone, a personal computer, a tablet terminal, or the like.
