DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the configurations shown in the following embodiments are merely examples, and the scope of the problem-solving means of the present disclosure is not limited to the configurations.

[0010] [Embodiment 1] 1 is a block diagram showing an example of the hardware configuration of each device included in the imaging system 1 according to the first embodiment.

For example, the communication unit 106 may communicate with the external device via another type of computer network such as a Wide Area Network (WAN).

[0013] The photographing unit 107 is an image sensor composed of at least one photographing element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide-Semiconductor) element, and converts an optical image into an electric signal. The display unit 108 is composed of an LED (Light Emitting Diode) or a liquid crystal panel, and displays a photographed image or the state of the photographing device 100. The information input unit 109 is composed of a touch panel or a button switch, and receives an operation input from a user. The power supply unit 110 is composed of a built-in battery such as a lithium ion battery or a removable portable battery, and supplies power to the photographing device 100. The power supply unit 110 may be configured to supply power to the photographing device 100 using power supplied from an external source such as an AC power source. The CPU 102 also operates as a control unit that controls each of the photographing unit 107, the display unit 108, and the information input unit 109.

[0014] The information processing device 150 is configured by a smartphone, a tablet terminal device, a notebook personal computer, or the like. The information processing device 150 has a CPU 152, a ROM 153, a RAM 154, a storage medium 155, a communication unit 156, a display unit 158, an information input unit 159, and a power supply unit 160, each of which is connected to each other via a bus so as to be able to communicate with each other. The hardware of the information processing device 150 has the same characteristics as the hardware of the same name of the photographing device 100, but may not be the same type of hardware as the photographing device 100.

[0015] Fig. 2 is a block diagram showing an example of the functional configuration of the photographing device 100 and the information processing device 150 in the photographing system 1 according to the first embodiment. The photographing device 100 has, as its functional configuration, a photographing unit 107, a server unit 201, a storage unit 202, and an output unit 205. The output unit 205 has a display control unit 206, a selection unit 207, and a transfer unit 208. The normal storage area 105a and the temporary storage area 105b in the storage medium 105 shown in Fig. 2 will be described later. The information processing device 150 has an application unit 250. The application unit 250 has a client unit 251 and a file receiving unit 252.

[0016] The server unit 201 operates as a web server such as an HTTP server or an HTTPS server, and provides web services to external devices such as the information processing device 150. The server unit 201 may provide a connection using another connection method such as Bluetooth (registered trademark) instead of the HTTP or HTTPS connection method. The client unit 251 of the information processing device 150 connects to the server unit 201 that provides web services as a web server, and performs data communication with the server unit 201.

[0017] The storage unit 202 acquires a captured image based on an electrical signal corresponding to an optical image output by the image capture unit 107, and encodes the captured image into a format such as JPEG or RAW if it is a still image, or into a format such as MP4 or MOV if it is a moving image to acquire a captured file. The storage unit 202 also stores the acquired captured file in the storage medium 105. The storage medium 105 has a normal storage area 105a and a temporary storage area 105b as storage areas for captured files. The normal storage area 105a is a storage destination for captured files captured by the image capture unit 107 and acquired by the storage unit 202 during a period when the client unit 251 is not connected to the server unit 201 (hereinafter referred to as a "disconnected period"). The temporary storage area 105b is a storage destination for captured files captured by the image capture unit 107 and acquired by the storage unit 202 during a period when the client unit 251 is connected to the server unit 201 (hereinafter referred to as a "connected period"). The details of the connected period and the disconnected period will be described later. The display control unit 206 displays the photographed files and the like stored in the storage medium 105 on the display unit 108. The selection unit 207 selects a photographed file to be transferred to the information processing device 150 from one or more photographed files stored in the temporary storage area 105b. Specifically, for example, the user of the photographing device 100 performs an operation to select a photographed file desired to be transferred to the information processing device 150 from one or more photographed files displayed on the display unit 108 using the information input unit 159. The selection unit 207 selects the photographed file based on the operation. The transfer unit 208 transfers (transmits) data of the photographed file selected by the selection unit 207 to the information processing device 150. The file receiving unit 252 of the information processing device 150 receives the data of the photographed file transferred by the transfer unit 208.

[0018] The processing of the image capturing device 100 and the information processing device 150 during the connection period will be described with reference to Figs. 3 to 6. Fig. 3 is a sequence diagram showing an example of the processing flow of the image capturing system 1 according to the first embodiment. Fig. 4 is a diagram showing an example of screen transitions on the display unit 108 of the image capturing device 100 and the display unit 158 ​​of the information processing device 150 according to the first embodiment. In the following description, the symbol "S" means a step (process).

[0019] When the user of the photographing device 100 selects a photographing request acceptance mode using the information input unit 109, the photographing device 100 displays a screen for confirming whether or not to start accepting a temporary photographing request (hereinafter referred to as a "photography request") on the display unit 108. Hereinafter, this screen will be referred to as a start confirmation screen 401. The start confirmation screen 401 includes a "Yes" button indicating consent to start accepting photographing requests and a "No" button indicating refusal to start accepting photographing requests. When the user of the photographing device 100 presses the "Yes" button on the start confirmation screen 401 using the information input unit 109, the process of the sequence diagram shown in FIG. 3 is started. First, in S301, the server unit 201 of the photographing device 100 starts providing a WEB service and starts accepting photographing requests.

[0020] On the other hand, when the user of the information processing device 150 selects the photographing request mode using the information input unit 159, the information processing device 150 displays a screen (hereinafter referred to as a "request confirmation screen 402") on the display unit 158 ​​to confirm whether or not to make a photographing request. The request confirmation screen 402 includes a "Yes" button indicating that a photographing request is to be made and a "No" button indicating that a photographing request is not to be made. When the user of the information processing device 150 presses the "Yes" button on the request confirmation screen 402 using the information input unit 159, in S302, the client unit 251 of the information processing device 150 transmits a connection request to the server unit 201 of the photographing device 100, and then a connection is established. In order to enable the user to confirm that the connection destination of the information processing device 150 is correct, the request confirmation screen 402 may include information capable of uniquely identifying the photographing device 100, such as the machine ID or network ID of the photographing device 100 to be connected.

[0021] After the connection with the photographing apparatus 100 is established, in S303, the client unit 251 of the information processing device 150 transmits (POSTs) a request for a photographing request (hereinafter referred to as a "photographing request request") to the server unit 201 of the photographing apparatus 100. The photographing request request transmitted from the information processing device 150 is received by the server unit 201 of the photographing apparatus 100. When the photographing apparatus 100 receives the photographing request request, the photographing apparatus 100 displays a screen (hereinafter referred to as an "acceptance confirmation screen 403") for confirming whether or not to accept the photographing request on the display unit 108. The acceptance confirmation screen 403 includes a "Yes" button indicating that the photographing request is accepted and a "No" button indicating that the photographing request is rejected. When the user of the photographing apparatus 100 presses the "Yes" button on the acceptance confirmation screen 403 using the information input unit 109, in S304, the photographing apparatus 100 transmits an acceptance notification indicating that the photographing request has been accepted to the information processing device 150.

[0022] After S304, in S305, the storage unit 202 of the photographing device 100 creates a new temporary storage area 105b in the storage medium 105. Next, in S306, the storage unit 202 of the photographing device 100 sets the storage destination of the photographed file to the temporary storage area 105b created in S305. Furthermore, when the information processing device 150 receives the acceptance notification, it displays a screen (hereinafter referred to as a "transfer request screen 404") for confirming whether or not to make a transfer request for the photographed file on the display unit 158. The transfer request screen 404 will be described later. After S306, the user of the photographing device 100 takes a photograph using the photographing device 100 in response to a request from the user of the information processing device 150. Specifically, when the user of the photographing device 100 presses the shutter button of the photographing device 100, in S307, the photographing device 100 executes the following process. Specifically, the photographing device 100 executes a photographing process, acquires a photographed file corresponding to a photographed image obtained by photographing, and stores the acquired photographed file in the storage medium 105.

[0023] The details of the process of S307 by the image capturing apparatus 100 will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of a series of process flows in image capturing by the image capturing apparatus 100 according to the first embodiment, and is a flowchart showing an example of the process flow in S307 shown in Fig. 3. When the user of the image capturing apparatus 100 presses the shutter button of the image capturing apparatus 100, first, in S501, the image capturing apparatus 100 executes image capturing process. Specifically, when the shutter button of the image capturing apparatus 100 is pressed, the image capturing unit 107 is exposed, and the image capturing unit 107 outputs an electrical signal corresponding to an optical image. Next, in S502, the storage unit 202 acquires an image file based on the electrical signal output by the image capturing unit 107.

[0024] Next, the photographing device 100 stores the photographed file in the storage medium 105. Specifically, in S503, the storage unit 202 judges whether the photographing process in S501 is based on a photographing request, that is, whether the photographing process in S501 is for a connection period. If it is judged in S503 that the photographing is not based on a photographing request, that is, that the photographing process in S501 is not for a connection period, in S504, the storage unit 202 stores the photographed file acquired in S502 in the normal storage area 105a in the storage medium 105. If it is judged in S503 that the photographing is based on a photographing request, that is, that the photographing process in S501 is for a connection period, in S505, the storage unit 202 stores the photographed file acquired in S502 in the temporary storage area 105b in the storage medium 105. In this embodiment, the storage destination of the photographed file is set to the temporary storage area 105b in S306, so the photographed file is stored in the temporary storage area 105b. After the process of S504 or S505, the image capturing apparatus 100 ends the process of the flowchart shown in FIG. 5, that is, the process of S307 shown in FIG.

[0025] After S307, in S308, the client unit 251 of the information processing device 150 transmits a file transfer request to the image capturing device 100 to request transmission (transfer) of the captured file. Specifically, for example, the user of the information processing device 150 causes the information processing device 150 to transmit the file transfer request using a transfer request screen 404 displayed on the display unit 158 ​​of the information processing device 150. More specifically, for example, the user of the information processing device 150 presses a "Yes" button included in the transfer request screen 404 for causing the information processing device 150 to transmit the file transfer request. When the "Yes" button on the transfer request screen 404 is pressed, the information processing device 150 transmits the file transfer request to the image capturing device 100. The process of S308 may be executed at any timing after the process of S304 and before the process of S310 described later.

[0026] Next, in S309, the selection unit 207 of the photographing device 100 selects a photographed file to be transferred to the information processing device 150. For example, the user of the photographing device 100 performs an operation to select a photographed file using a screen (not shown) for selecting a photographed file displayed on the display unit 108 and the information input unit 109, and the selection unit 207 selects the photographed file based on the input of the operation. Next, in S310, the transfer unit 208 of the photographing device 100 transfers (transmits) data of the photographed file selected in S309 to the information processing device 150. The data of the photographed file transmitted from the photographing device 100 is received by the file receiving unit 252 of the information processing device 150. After S310, the photographing device 100 and the information processing device 150 perform end processing in a series of processing based on the photographing request.

[0027] 6 is a diagram showing an example of screen transition on the display unit 108 of the image capturing apparatus 100 according to the first embodiment and the display unit 158 ​​of the information processing apparatus 150, and is a diagram showing an example of screen transition during end processing in a series of processes based on an image capturing request. After S310, the image capturing apparatus 100 displays a screen (hereinafter referred to as "end confirmation screen 601") on the display unit 108 to confirm with the user of the image capturing apparatus 100 whether or not to temporarily end the image capturing requested. The end confirmation screen 601 includes, for example, a "Yes" button indicating consent to temporarily end the image capturing requested, and a "No" button indicating refusal to temporarily end the image capturing requested.

[0028] When the user of the photographing device 100 presses the "No" button on the end confirmation screen 601, for example, the processes from S307 to S310 may be repeatedly executed until the "Yes" button on the end confirmation screen 601 is pressed. When the user of the photographing device 100 presses the "Yes" button on the end confirmation screen 601, in S311, the storage unit 202 of the photographing device 100 deletes all photographed files stored in the temporary storage area 105b of the storage medium 105. When the deletion of the photographed files is completed in S311, the photographing device 100 displays on the display unit 108 a deletion completion screen 602 indicating that all photographed files acquired based on a photographing request and stored in the storage medium 105 have been deleted.

[0029] After S311, in S312, the server unit 201 of the photographing device 100 transmits a disconnection notification to the information processing device 150, indicating that the connection between the photographing device 100 and the information processing device 150 will be disconnected. When the client unit 251 of the information processing device 150 receives the disconnection notification, the information processing device 150 displays on the display unit 158 ​​a request completion screen 603 indicating that the photographed files stored in the photographing device 100 have been deleted and that the connection with the photographing device 100 has been disconnected. By displaying the request completion screen 603, the user of the information processing device 150 can recognize that the photographed files based on the photographing request will not be deleted and diverted, and can feel at ease.

[0030] After S312, in S313, the server unit 201 of the photographing device 100 ends the Web service. Next, in S314, the storage unit 202 of the photographing device 100 sets the storage destination of the photographed file to the normal storage area 105a. Next, in S315, the storage unit 202 of the photographing device 100 deletes the temporary storage area 105b generated in S305 from the storage medium 105. By deleting the temporary storage area 105b, it is possible to prevent the user of the photographing device 100 from accessing the photographed file based on the photographing request thereafter. After S315, the photographing system 1 ends the process of the sequence diagram shown in FIG. 3, that is, the series of processes in photographing by the photographing device 100.

[0031] In the above description, the deletion completion screen 602 is described as being displayed when the deletion of the captured file is completed in S311, but may be configured to be displayed when the deletion of the temporary storage area 105b is completed. In addition, the process of S313 is described as being executed before the process of S314, but the process of S313 may be executed at any timing after the process of S312. In addition, the process of S314 is described as being executed after the process of S313, but the process of S313 may be executed at any timing after the "Yes" button on the end confirmation screen 601 is pressed. In addition, the process of S315 is described as being executed after the process of S314, but the process of S315 may be executed at any timing after the "Yes" button on the end confirmation screen 601 is pressed.

[0032] Although the connection between the photographing device 100 and the information processing device 150 has been described as continuing from when the connection is established until when it is disconnected, the photographing device 100 and the information processing device 150 may be connected only when communication between the devices is necessary. In this case, the above-mentioned connection period corresponds to the period from when the photographing request is accepted by the photographing device 100 until photographing based on the photographing request is completed, and the non-connection period corresponds to the period other than the connection period.

[0033] Furthermore, in the case of shooting during the connection period, the storage unit 202 of the photographing device 100 may acquire a photographed file including information indicating that the photographed file is based on a photographing request in the attribute information of the photographed file. In this case, in S310, the storage unit 202 of the photographing device 100 may delete the photographed file including the information in the attribute information. Here, the attribute information of the photographed file is, for example, information of Exif (Exchangeable Image File Format) in the photographed file. In this way, by including information indicating that the photographed file is based on a photographing request in the attribute of the photographed file, the user of the information processing device 150 can confirm whether the photographed file is based on a photographing request.

[0034] As described above, when the photographing device 100 disconnects the connection established with the information processing device 150, that is, when the photographing based on the photographing request is terminated, the photographing file acquired based on the photographing request is deleted. According to such a photographing device 100, the photographing file acquired based on the photographing request can be reliably deleted from the photographing device 100, and when a photographing request is received, it is possible to suppress the diversion of the photographing file without the permission of the person who requested the photographing while suppressing cumbersome work. In addition, when the photographing device 100 accepts a request for a photographing request, it generates the temporary storage area 105b, and when the photographing based on the photographing request is terminated, it deletes the temporary storage area 105b. According to such a photographing device 100, since it is not necessary to secure the unnecessary temporary storage area 105b during the non-connection period, it is possible to increase the capacity of the normal storage area 105a. In addition, the photographing device 100 stores the photographing file based on the photographing request in the temporary storage area 105b different from the normal storage area 105a. According to the photographing device 100, the user of the photographing device 100 can manage the photographing files based on normal photographing and the photographing files based on the photographing request by separating them into storage areas. Therefore, it is possible to prevent the user of the photographing device 100 from accidentally deleting the photographing files stored in the normal storage area 105a.

[0035] In the present embodiment, the photographed files are stored in the storage medium 105 of the photographing device 100. However, the storage destination of the photographed files may be a storage device disposed outside the photographing device 100, such as a cloud storage service. In this case, the photographing device 100 may delete the photographed files stored in the external storage device or delete the storage area of ​​the photographed files in the storage device when completing the photographing based on the photographing request. By configuring in this way, the photographed files stored in the external storage device can be deleted in the same way as the photographed files stored in the temporary storage area 105b of the storage medium 105 of the photographing device 100.

[0036] In addition, in the present embodiment, an example has been shown in which the captured file is deleted to disable access to the captured file thereafter, but the captured file does not necessarily have to be deleted. For example, if the captured file is deleted from the storage medium 105 of the photographing device 100, the captured file cannot be accessed again. However, when the connection between the photographing device 100 and the information processing device 150 is suddenly cut off, the captured file may be unintentionally deleted from the storage medium 105 of the photographing device 100. Alternatively, after executing the deletion process of the captured file, the user may want to cancel the deletion process, or the user of the information processing device 150 may want to resend the deleted captured file.

[0037] Therefore, for example, the photographing device 100 may be configured to conceal the photographed file based on the photographing request based on an encryption key that can only be known by the information processing device 150 or the user of the information processing device 150. By concealing the photographed file in this way, it is possible to disable the user of the photographing device 100 from accessing the photographed file thereafter. Also, by concealing the photographed file in this way, it is possible to enable the user of the photographing device 100 to access the photographed file stored in the photographing device 100 only while the information processing device 150 is connected to the photographing device 100, thereby enabling the user of the photographing device 100 to resend the photographed file.

[0038] [Embodiment 2] The photographing device 100 according to the first embodiment deletes a photographed file acquired based on a photographing request when disconnecting the connection between the photographing device 100 based on the photographing request and the information processing device 150. In the second embodiment, a form will be described in which the information processing device 150 requests the photographing device 100 to delete a photographed file, and the photographing device 100 deletes the photographed file when the photographing device 100 receives the deletion request. The hardware configuration and functional configuration of the photographing device 100 and the information processing device 150 in the photographing system 1 according to the second embodiment are similar to those of the photographing device 100 and the information processing device 150 in the photographing system 1 according to the first embodiment, and therefore description thereof will be omitted.

[0039] With reference to Figs. 7 and 8, the processing of the image capturing device 100 and the information processing device 150 (hereinafter simply referred to as "image capturing device 100 and information processing device 150") according to the second embodiment during a connection period will be described. Fig. 7 is a sequence diagram showing an example of a processing flow of the image capturing system 1 (hereinafter simply referred to as "image capturing system 1") according to the second embodiment. Fig. 8 is a diagram showing an example of a screen transition in the display unit 108 of the image capturing device 100 and the display unit 158 ​​of the information processing device 150 according to the second embodiment. Note that in Fig. 7, processing similar to the processing in the sequence diagram shown in Fig. 3 is denoted by the same reference numerals and description thereof will be omitted.

[0040] First, the photographing device 100 or the information processing device 150 executes the processes from S301 to S310. After the information processing device 150 receives the photographed file data transmitted in S310, in S701, the client unit 251 of the information processing device 150 transmits a request to delete the photographed file (hereinafter referred to as a "file deletion request") to the photographing device 100. Specifically, when the information processing device 150 receives the photographed file data, it displays a deletion request screen 801 on the display unit 158 ​​for confirming whether or not to delete the photographed file based on the photographing request stored in the temporary storage area 105b of the storage medium 105. The deletion request screen 801 includes, for example, a "Yes" button indicating that the photographed file is requested to be deleted from the photographing device 100, and a "No" button indicating that the photographed file is not requested to be deleted.

[0041] When the user of the information processing device 150 uses the information input unit 159 to press the "Yes" button on the deletion request screen 801, a file deletion request is transmitted from the information processing device 150 to the photographing device 100. The file deletion request transmitted from the information processing device 150 is received by the server unit 201 of the photographing device 100. Upon receiving the file deletion request, the photographing device 100 executes the process of S311 to delete the photographed file stored in the temporary storage area 105b of the storage medium 105. Upon completion of the deletion of the photographed file, the photographing device 100 displays on the display unit 108 a deletion completion screen 802 indicating that the deletion of the photographed file stored in the temporary storage area 105b of the storage medium 105 has been completed.

[0042] After S311, in S702, the server unit 201 of the photographing device 100 transmits a notification (hereinafter referred to as a "deletion completion notification") indicating that the photographed file based on the photographing request has been deleted to the information processing device 150. The deletion completion notification transmitted from the photographing device 100 is received by the client unit 251 of the information processing device 150. Upon receiving the deletion completion notification, the information processing device 150 displays on the display unit 158 ​​a deletion completion screen 803 indicating that the photographed file stored in the photographing device 100 has been deleted.

[0043] After S702, the processes from S312 to S315 are executed by the photographing device 100 or the information processing device 150. After S315, the photographing system 1 ends the process of the sequence diagram shown in Fig. 7, i.e., a series of processes for photographing by the photographing device 100. Note that, when the information processing device 150 receives the disconnection notification transmitted from the photographing device 100 in S312, the information processing device 150 may display, on the display unit 158, a disconnection completion screen (not shown) indicating that the connection with the photographing device 100 has been disconnected.

[0044] As described above, the photographing device 100 deletes the photographed file acquired and stored based on the photographing request in response to a request to delete the photographed file from the information processing device 150. According to such a photographing system 1, the user of the information processing device 150 can explicitly or voluntarily request the deletion of the photographed file.

[0045] [Embodiment 3] The photographing device 100 according to the first and second embodiments deletes a photographed file based on a photographing request, which is stored in the temporary storage area 105b, after transferring it to the information processing device 150. In the third embodiment, a form will be described in which the photographing device 100 stores a photographed file stored in the temporary storage area 105b in the normal storage area 105a when a request to store the photographed file is received from the information processing device 150. By storing the photographed file in the normal storage area 105a, the user of the photographing device 100 can normally access the photographed file thereafter. The hardware configuration and functional configuration of the photographing device 100 and the information processing device 150 in the photographing system 1 according to the third embodiment are similar to those of the photographing device 100 and the information processing device 150 in the photographing system 1 according to the first or second embodiment, and therefore will not be described.

[0046] With reference to Figs. 9 to 11, the processing of the image capturing device 100 and the information processing device 150 (hereinafter simply referred to as "image capturing device 100 and information processing device 150") according to the third embodiment during a connection period will be described. Fig. 9 is a sequence diagram showing an example of a processing flow of the image capturing system 1 (hereinafter simply referred to as "image capturing system 1") according to the third embodiment. Fig. 10 is a diagram showing an example of a screen transition on the display unit 108 of the image capturing device 100 and the display unit 158 ​​of the information processing device 150 according to the third embodiment. Note that in Fig. 9, processing similar to that in the sequence diagram shown in Fig. 3 or 7 is denoted by the same reference numerals and description thereof will be omitted.

[0047] First, the photographing device 100 or the information processing device 150 executes the processes from S301 to S310. After the information processing device 150 receives the photographed file data transmitted in S310, in S901, the client unit 251 of the information processing device 150 transmits a photographed file operation request (hereinafter referred to as a "file operation request") to the photographing device 100. Specifically, when the information processing device 150 receives the photographed file data, it displays on the display unit 158 ​​a save confirmation screen 1001 for confirming whether or not to save the photographed file acquired by the photographing device 100 based on the photographing request in the storage medium 105 of the photographing device 100. The save confirmation screen 1001 includes, for example, a "Yes" button indicating that the photographed file is requested to be saved to the photographing device 100, and a "No" button indicating that the photographed file is not requested to be saved.

[0048] When the user of the information processing device 150 presses the "Yes" button on the save confirmation screen 1001 using the information input unit 159, a save request for the captured file is transmitted from the information processing device 150 to the photographing device 100 as a file operation request. On the other hand, when the user of the information processing device 150 presses the "No" button on the save confirmation screen 1001, for example, a delete request for the captured file is transmitted from the information processing device 150 to the photographing device 100 as a file operation request. The file operation request transmitted from the information processing device 150 is received by the server unit 201 of the photographing device 100. Upon receiving the file operation request, the photographing device 100 performs a file operation corresponding to the file operation request on the captured file stored in the temporary storage area 105b of the storage medium 105 in S902.

[0049] The details of the process of S902 by the photographing device 100 will be described with reference to Fig. 11. Fig. 11 is a flowchart showing an example of a series of processes in a file operation of a photographed file by the photographing device 100 according to the third embodiment, and is a flowchart showing an example of the process flow of S902 shown in Fig. 9. First, in S1101, the storage unit 202 of the photographing device 100 determines whether or not the file operation request received by the server unit 201 of the photographing device 100 is a request to save a photographed file.

[0050] When it is determined in S1101 that the file operation request is a request to save a captured file, in S1103, the saving unit 202 of the photographing device 100 moves the captured file saved in the temporary saving area 105b of the storage medium 105 to the normal saving area 105a. In this case, the saving unit 202 may copy the captured file saved in the temporary saving area 105b of the storage medium 105 to the normal saving area 105a.

[0051] After S1103, the photographing device 100 may display on the display unit 108 a storage completion screen 1002 indicating that the photographed file stored in the temporary storage area 105b has been stored in the normal storage area 105a. Also, after S1103, the server unit 201 of the photographing device 100 may transmit to the information processing device 150 a storage completion notification indicating that the photographed file based on the photographing request has been stored in the storage medium 105 of the photographing device 100. In this case, the storage completion notification transmitted from the photographing device 100 is received by the client unit 251 of the information processing device 150. Furthermore, when the information processing device 150 receives the storage completion notification, the information processing device 150 may display on the display unit 158 ​​a storage completion screen 1002 indicating that the photographed file based on the photographing request has been stored in the storage medium 105 of the photographing device 100.

[0052] When it is determined in S1101 that the file operation request is not a request to save the captured file, for example, when the file operation request is a request to delete the captured file, in S1102, the storage unit 202 deletes the captured file stored in the temporary storage area 105b. After S1102, the photographing device 100 may display on the display unit 108 a screen (for example, a deletion completion screen 802 shown in FIG. 8) indicating that the captured file stored in the temporary storage area 105b has been deleted from the storage medium 105. Also, after S1102, the server unit 201 of the photographing device 100 may transmit a deletion completion notification to the information processing device 150 indicating that the captured file based on the photographing request has been deleted from the storage medium 105. In this case, the deletion completion notification transmitted from the photographing device 100 is received by the client unit 251 of the information processing device 150. Furthermore, when the information processing device 150 receives a deletion completion notification, the information processing device 150 may display on the display unit 158 ​​a screen (e.g., deletion completion screen 803) indicating that the shooting file based on the shooting request has been deleted from the storage medium 105 of the shooting device 100.

[0053] After S1102 or S1103, the photographing device 100 ends the process of the flowchart shown in Fig. 11, i.e., the process of S902 shown in Fig. 9. After S902, the photographing device 100 or the information processing device 150 executes the processes from S312 to S315. After S315, the photographing system 1 ends the process of the sequence diagram shown in Fig. 9, i.e., the series of processes in photographing by the photographing device 100.

[0054] In addition, when the photographing based on the photographing request is continuously performed repeatedly after S902, that is, when the processing from S307 to S902 is performed repeatedly after S902, the processing of S901 may be omitted in the repeated processing. For example, when the file operation request in the first S901 is a request to save the photographed file, the storage unit 202 of the photographing device 100 sets the storage destination of the photographed file to the normal storage area 105a and saves the subsequent photographed files in the normal storage area 105a. In addition, in the above description, the processing of S901 is described as being executed after S310, but it may be executed at any timing between the processing of S304 to S902. For example, when the processing of S901 is executed before the processing of S306, the photographing device 100 may set the storage destination of the photographed file to the normal storage area 105a in S306. That is, in this case, the photographing device 100 saves all the photographed files including the photographed file corresponding to the first photographing based on the photographing request in the normal storage area 105a.

[0055] In addition, in the above description, the file operation request in S901 includes a request to delete and a request to save the captured file, but it may be configured to transmit only a file operation request corresponding to a save request. Specifically, for example, the file operation request is configured not to be transmitted when the user of the information processing device 150 presses the "No" button on the save confirmation screen 1001. In this case, for example, when the image capturing device 100 does not receive a file operation request until a predetermined period of time has elapsed since the processing of S310, it may delete the captured file by assuming that consent to the saving of the captured file has not been obtained from the user of the information processing device 150.

[0056] According to the photographing device 100 configured as above, the photographed file based on the photographing request can be not only deleted but also left as it is stored in the photographing device 100. For example, the user of the information processing device 150 may provide the photographed file acquired by photographing based on the photographing request to the user of the photographing device 100. In such a case, the user of the information processing device 150 can explicitly or voluntarily instruct the photographed file to be stored in the photographing device 100 using the storage confirmation screen 1001 or the like. When the information processing device 150 requests the photographed file to be stored in the photographing device 100, the photographed file can be stored in the normal storage area 105a where the photographed file is not deleted. This prevents the photographed file acquired by photographing based on the photographing request from being deleted from the photographing device 100.
