  On the other hand, when the file name of the determination file is received, YES is determined in the step S72, and the process proceeds to the step S73.

  On the other hand, if it is determined that the determination file has been received, YES is determined in the step S71, and the process proceeds to a step S73.

In step S73, the file name acquisition unit 102 acquires a file name. Specifically, when the file name acquisition unit 102 acquires a file in step S71, the file name acquisition unit 102 searches for the file name from the file data and acquires a file name for performing the same determination.
In addition, when the file name acquisition unit 102 acquires the file name information in step S72, the file name acquisition unit 102 acquires the file name from the data of the file name information. The file name acquired by the file name acquisition unit 102 is a target for determining the identity.

  In step S 74, the file name search unit 103 accesses the first file in the image file storage unit 62. In this embodiment, a plurality of image files are sequentially determined in the order of addresses. In this step, the file to be determined first is accessed based on the address.

  In step S75, the file name search unit 103 accesses the Exif information. That is, in step S74, the file name search unit 103 accesses the Exif area of the accessed file and acquires Exif information. In the Exif information, information related to the file name such as the file name before the change is stored.

In step S76, the same file determination unit 104 determines whether there is an identical file name. That is, the same file determination unit 104 compares the file name acquired in step S73 with the information on the file name stored in the Exif information acquired in step S75, and determines whether there is an identical file name. Determine.
If it is determined that the same file name exists, YES is determined in step S76, and the process proceeds to step S77.

  In step S77, the notification control unit 105 performs notification that the corresponding file exists. In other words, the notification control unit 105 controls the output unit 18 so as to output, for example, display output so as to notify that the same file name exists when there is a corresponding file. As a result, the output unit 18 displays “same file exists” or the like. By viewing the display output on the output unit 18, the user performs operations such as overwriting / deleting files and changing file names, for example. Thereafter, the identical file name determination process ends.

  On the other hand, if it is determined that the same file name does not exist, NO is determined in step S76, and the process proceeds to step S78.

  In step S78, the file name search unit 103 determines whether there is a next file. That is, the file name search unit 103 searches the image file storage unit 62 in the order of addresses to determine whether there is an image file that has not been determined yet.

  If it is determined that there is a next file, YES is determined in step S78, the process returns to step S75, and the processes after step S75 are performed. That is, the same file name is determined for the image files stored at the subsequent addresses.

  On the other hand, if it is determined that there is no file, NO is determined in step S78, and the process proceeds to step S79.

  In step S79, the notification control unit 105 performs notification that there is no corresponding file. In other words, the notification control unit 105 controls the output unit 18 so as to output, for example, display output so as to notify that there is no same file name as no corresponding file. As a result, the output unit 18 displays “No identical file”. The user sees the display output on the output unit 18 and performs operations such as file registration, for example. Thereafter, the identical file name determination process ends.

The imaging apparatus 1 configured as described above includes a captured image generation unit 81, a file name generation unit 82, and an image file generation unit 83.
The captured image generation unit 81 generates captured image data and a normal file name of the file.
The file name generation unit 82 generates (specifies) a transfer destination file name corresponding to a predetermined transfer destination to which the file generated by the captured image generation unit 81 is transferred.
The image file generation unit 83 associates the transfer destination with the transfer destination file name generated (specified) by the file name generation unit 82, adds it to the file as additional information, and stores it in the image file storage unit 62.
For this reason, the imaging apparatus 1 associates the transfer destination with the transfer destination file name generated (specified) by the file name generation unit 82, adds it to the file as additional information, and stores it in the image file storage unit 62.
Therefore, the imaging apparatus 1 retains the file name of the transfer destination even when the file name is changed to the transfer destination file name and becomes a file name different from the file name at the time of file generation. In addition, the identity of the file can be determined by confirming the held transfer destination file name.

The imaging apparatus 1 further includes a transfer control unit 93 and a file name change unit 92.
The transfer control unit 93 controls the communication unit 20, the drive 21, and the like so as to transfer the file to the transfer destination stored in the file additional information.
When the transfer control unit 93 performs control to transfer the file to the transfer destination, the file name change unit 92 stores the file name of the file to be transferred in association with the transfer destination stored in the additional information Change the name.
Therefore, in the imaging apparatus 1, it is possible to transfer the file by changing the file name automatically to an appropriate file without taking time and effort according to the transfer destination.
Further, in the imaging apparatus 1, the information on the file name can be changed to the file name corresponding to the transfer destination without having to be managed by the storage means or the like.

In the imaging apparatus 1, the file name generation unit 82 generates (identifies) a file name corresponding to the transfer destination when the captured image generation unit 81 generates a file. In addition, the image file generation unit 83 adds the file name generated by the transfer destination and the captured image generation unit 81 to the file as additional information and stores it.
Therefore, since the image capturing apparatus 1 stores the file by adding the additional information related to the transfer file name when generating the image file, the file size is not changed later. In other words, when the transfer destination file name is added after the file generation, it will be different from the original file size. However, in the imaging apparatus 1, since the size is not changed from the original file, Advantages such as the ability to perform planned file management occur.

The imaging apparatus 1 further includes a transfer destination setting unit 51 that sets a transfer destination.
The file name generation unit 82 generates (specifies) a file name corresponding to the transfer destination set by the transfer destination setting unit 51.
Therefore, in the imaging apparatus 1, the transfer destination can be arbitrarily set.

Further, the file name generation unit 82 generates a transfer file name so as not to overlap with the transfer file name generated last time.
Therefore, since the imaging device 1 is configured so that the generated transfer file names do not overlap with each other, even when the file name is changed during transfer, duplication of the file name at the transfer destination can be avoided.

The imaging apparatus 1 further includes a file name acquisition unit 102, an identical file determination unit 104, and a notification control unit 105.
The file name acquisition unit 102 acquires a file or a file name of the file from the transfer destination.
The same file determination unit 104 determines whether or not the file name or the file name of the file acquired by the file name acquisition unit 102 is included in the additional information of any file stored in the imaging device 1. To do.
The notification control unit 105 performs control to notify the output unit 18 and the like of the determination result by the same file determination unit 104.
Therefore, in the imaging apparatus 1, when a file that is considered to have a similar transfer destination is acquired from another location, it is possible to determine whether or not the file is a file generated by the imaging apparatus 1. .

Further, the file handled in the present embodiment is an image file, and the additional information of the transfer destination file name is stored in the Exif area in the image file.
Therefore, the image pickup apparatus 1 can easily manage the transfer of image files.

  In addition, this invention is not limited to the above-mentioned embodiment, The deformation | transformation in the range which can achieve the objective of this invention, improvement, etc. are included in this invention.

In the embodiment described above, the transfer destination file name is generated and stored in the image file (Exif area) when generating the image file in consideration of the subsequent increase in the file size of the image file. Not limited.
The storage time of the transfer destination file name in the image file (Exif area) may be configured to be performed when the transfer destination file name is transferred (or until the file transfer). In this case, if a predetermined area is reserved for storing the transfer destination file name when generating the image file, there is no subsequent increase in the file size, and the transfer destination file name is transferred to the image file (Exif area). Can be stored.
Further, the generation time of the transfer destination file name is not limited to the time of generating the image file, but can be configured to be generated at the time of file transfer (or until the file transfer). With such a configuration, a transfer destination file name is not generated when an image file is generated, so that the processing load when generating the image file can be reduced.

  In the above-described embodiment, the external device T to which the file is transferred from the imaging device 1 serving as the transfer source makes a request for identity determination without changing the file name thereafter. For example, when the file name is changed at the transfer destination, the transfer destination external device T notifies the transfer source imaging device 1 of the change of the file name, and the transfer source image pickup device 1 transfers the corresponding file. You may comprise so that the file name newly changed to the file name may be added or updated. With this configuration, even when the file is changed at the transfer destination (external device T), if a request for determining identity is made to the transfer source device (imaging device 1), the file name Since the data including the change is held, the identity can be determined.

  In the above-described embodiment, the identity of the file is determined between the imaging device 1 and another external device T, that is, between the device that generated the image file and the device to which the file is transferred from the device. However, it is not limited to this. The identity of the file is determined by the apparatus (image capturing apparatus 1) that generated the image file, the external apparatus (for example, the first service server apparatus T1) to which the file is transferred, and the external apparatus (for example, PCT3). Alternatively, the file may be transferred between the external devices (between the first service server devices T1 and PCT3) in a state where the file is transferred.

  In the above-described embodiment, the file to be handled is an image file, but the present invention is not limited to this. The file may be, for example, a moving image file, a document file, or the like, and may be any file that is used under the condition that the file name is changed to a file name different from the saved ordinary file name.
