The digital camera 101 and the tablet 102 can communicate via Wi-Fi (registered trademark), Bluetooth (registered trademark) LE, USB, or the like. The digital camera 101 and the PC 103 can communicate similarly.

  The digital camera 101 is an example of an imaging device. The tablet 102 and the PC 103 are both examples of an information processing apparatus, and are examples of an external apparatus for the imaging apparatus. In the present embodiment, the tablet 102 is an example of a transmission destination of a captured image. The tablet 102 is an example of an apparatus for notifying the user that transmission of a captured image from the digital camera 101 to the PC 103 has become possible. A smartphone may be used instead of the tablet 102.

  The digital camera 101 of the present embodiment generates a sub-image from a captured image when generating the captured image. The sub-image is an image in which the amount of data is reduced by reducing the compression rate, the number of pixels, the bit depth and the like with respect to the captured image, and is an image that can be displayed as proxy data of the captured image. Further, the image identifier of the photographed image is associated with the sub image. That is, the photographed image and the sub-image are associated with each other by this image identifier. Further, in the present embodiment, the photographed image is a RAW file including RAW image data in a state in which the development processing has not been completed. The sub image is an image obtained by performing image processing on the RAW image so that the data amount (number of pixels) is smaller than that of the captured image. That is, the sub-image is an image having a smaller amount of data (number of pixels) compared to the photographed image. The sub image may be a developed image file including developed data subjected to development processing or compression processing into a predetermined format such as JPEG. That is, the sub image may be a JPEG image.

  Further, it is assumed that the PC 103 has a larger processing capacity and data storage capacity than the tablet 102, and can execute development processing of a captured image to display a development result. In response to such a configuration, the digital camera 101 transmits a sub image with a small amount of data to the tablet 102, and transmits a captured image to the PC 103. As a result, the user can display and view the sub-image on the tablet 102 promptly after shooting. Furthermore, the user performs editing of metadata such as ratings, comments, tags, etc., and images such as brightness, white balance, color gradation, color density, sharpness, noise reduction, color space, etc. on the tablet 102.

The communication unit 208 is an interface for connecting to a network line such as the Internet or an interface for communicating with an external device such as the tablet 102 or the PC 103.

  The imaging unit 209 captures an image. The image processing unit 210 performs image processing on the image obtained by the imaging unit 209. The image processing unit 210 generates, for example, a sub image from a captured image. The control unit 201 assigns an image identifier to the photographed image obtained by the photographing unit 209, associates the photographed image with the image identifier, and stores the image in the recording medium 204. Furthermore, when the sub-image is generated by the image processing unit 210, the control unit 201 stores the sub-image in the recording medium 204 in association with the image identifier of the captured image of the generation source of the sub-image. Note that as another example, the control unit 201 may perform image processing such as generation of a sub image. In this case, the digital camera 101 may not have the image processing unit 210.

  FIG. 3 is a hardware configuration diagram of the tablet 102. As shown in FIG. The tablet 102 includes a control unit 301, a ROM 302, a RAM 303, a recording medium 304, a device IF 305, an input unit 306, a display unit 307, and a communication unit 308. The control unit 301, the ROM 302, the RAM 303, the recording medium 304, the device IF 305, the input unit 306, the display unit 307, and the communication unit 308 are the same as the corresponding units 201 to 208 of the digital camera 101 described with reference to FIG. is there. Also, the hardware configuration of the PC 103 is the same as the hardware configuration of the tablet 102.

  FIG. 4 is a view showing an example of the data configuration of the digital camera 101. As shown in FIG. The digital camera 101 stores the photographed image table 400 shown in FIG. 4A and the transfer destination list 410 shown in FIG. 4B in, for example, a storage unit such as the recording medium 204. The photographed image table 400 stores the photographed image, the image identifier for identifying the photographed image, and the editing information in association with each other. The editing information is information indicating the content of the editing process performed on the sub image generated from the captured image. The editing information includes, for example, setting values in the editing process.

  In the example of FIG. 4A, five captured images 1 to 5 are stored, and image identifiers A to E are stored in association with the respective captured images. Note that the recording medium 204 may store the photographed image, the image identifier, and the editing information in association with one another, and a specific data configuration therefor is not limited to the embodiment. As another example, the recording medium 204 may store the image identifier and the editing information as separate files from the photographed image. As another example, the recording medium 204 may store the image identifier and the editing information in the captured image file. The digital camera 101 stores the photographed image and the image identifier in the photographed image table 400 when the photographed image is obtained. Furthermore, when the digital camera 101 receives editing information from the tablet 102, the digital camera 101 stores the editing information in the photographed image table 400.

  The transfer destination list 410 shown in FIG. 4B stores the address of the transfer destination to which the photographed image has been transferred. When the digital camera 101 is connected to the PC 103 and transmits a photographed image to the PC 103, the digital camera 101 receives a terminal identifier such as an address of the PC 103 from the PC 103, and stores this in the transfer destination list 410.

  FIG. 5 is a view showing an example of the data configuration of the sub image table stored in the tablet 102. As shown in FIG. The tablet 102 stores the sub image table 500 in a storage unit such as a recording medium 304, for example. The sub image table 500 stores the sub image, the image identifier corresponding to the sub image, and the editing information in association with each other. Here, the image identifier is an image identifier of a captured image which is a generation source of the sub image. When the tablet 102 receives the sub image and the image identifier from the digital camera 101, the tablet 102 stores these in the sub image table 500. Further, the editing information is stored in the sub image table 500 when the editing process is performed in the tablet 102. Therefore, the editing information is not stored before the editing process is performed.

  FIG. 6 is a view showing an example of the data configuration of a photographed image table stored in the PC 103. The PC 103 stores the photographed image table 600 in, for example, a storage medium. The photographed image table 600 stores the photographed image, the image identifier of the photographed image, and the editing information in association with each other. When the PC 103 receives a captured image and an image identifier from the digital camera 101, the PC 103 stores these in the captured image table 600. Furthermore, when the editing information and the image identifier are received from the digital camera 101, the PC 103 stores the editing information in the photographed image table 600 in association with the corresponding image identifier.

  FIG. 7 is a flowchart showing information processing by the digital camera 101. In step S <b> 701, the control unit 201 of the digital camera 101 acquires a photographed image obtained by the photographing process by the photographing unit 209. The control unit 201 further associates the captured image with the image identifier and stores the captured image in the captured image table 400. Next, in step S702, the control unit 201 instructs the image processing unit 210 to generate a sub image based on the captured image acquired in step S701, and acquires the sub image from the image processing unit 210. Note that the processes of S701 and S702 are an example of an acquisition process for acquiring a captured image and a sub image.

  Next, in step S703, the control unit 201 determines whether the tablet 102 is connected to the digital camera 101. If the tablet 102 is connected (YES in S703), the control unit 201 advances the process to S704. If the tablet 102 is not connected (NO in S703), the control unit 201 advances the process to S707. In step S704, the control unit 201 associates the sub image acquired in step S702 with the image identifier of the captured image of the generation source of the sub image, and transmits it to the tablet 102 of the connection destination via the communication unit 208.

  When the tablet 102 receives the sub-image and the image identifier, the tablet 102 associates the received sub-image and the image identifier and stores them in the sub-image table 500. Thereby, the tablet 102 can display the sub image on the display unit 307 of the own device immediately after photographing with the digital camera 101. Thus, the user can view the sub-image using the tablet 102. Furthermore, the tablet 102 can perform the editing process on the sub image in accordance with the user operation. Here, the editing process is a process of image adjustment such as rating, color label, brightness, white balance, color gradation, color density, sharpness, noise reduction, color space and the like.

  When the tablet 102 performs the editing process, the tablet 102 generates editing information indicating the content of the editing process, stores the editing information in the sub-image table 500 in association with the image identifier of the sub-image. Here, the editing information includes the adjustment value and the change date and time set in the editing process. When the tablet 102 performs the editing process, the tablet 102 further associates the editing information with the image identifier, and transmits it to the digital camera 101 which is the transmission source of the sub image.

  On the other hand, after the process of S704, the control unit 201 receives the editing information and the image identifier from the tablet 102 via the communication unit 208 in S705. Next, in S706, the control unit 201 searches the captured image table 400 for the received image identifier, and stores the received editing information in association with the matching image identifier. In addition, when the editing information is already stored in the captured image table 400 in association with the received image identifier, the control unit 201 confirms the change date and time. Then, the control unit 201 updates the received editing information when the modification date of the received editing information is new, and does not perform updating when the editing information already stored is stored. When the tablet 102 transmits the editing information and the image identifier to the digital camera 101, the tablet 102 resets the editing information for which transmission has been completed.

  Next, in step S 707, the control unit 201 determines whether the PC 103 is connected to the digital camera 101. If the PC 103 is connected (YES in S707), the control unit 201 advances the process to S708. If the PC 103 is not connected (NO in S707), the control unit 201 advances the process to S712. In step S 708, the control unit 201 transmits the photographed image stored in the photographed image table 400 and the image identifier to the PC 103 of the connection destination via the communication unit 208. When receiving the photographed image and the image identifier, the PC 103 associates the received photographed image with the image identifier and stores the received photographed image and the image identifier in the photographed image table 600. When transmitting the photographed image, the control unit 201 further controls the display unit 207 to display information indicating the external device of the transmission destination of the photographed image. This process is an example of the display control process.

  Next, in step S709, the control unit 201 deletes the photographed image transmitted in step S708 from the photographed image table 400. At this time, the control unit 201 controls so as not to delete the image identifier associated with the captured image. Note that the control unit 201 may not delete the captured image. In addition, after the process of S 708, the control unit 201 may delete the photographed image when the deletion instruction is received by the user operation. Next, in step S710, the control unit 201 receives the terminal identifier of the PC 103 from the PC 103, and stores the received terminal identifier in the transfer destination list 410.

  Next, in step S711, the control unit 201 confirms whether or not the transfer destination list 410 stores a terminal identifier that matches the terminal identifier of the connected PC 103. Then, when a matching terminal identifier is stored, the control unit 201 transmits editing information associated with the image identifier transmitted in S708 in the photographed image table 400 to the PC 103 together with the image identifier. . When receiving the editing information and the image identifier, the PC 103 searches the captured image table 600 for the received image identifier, and stores the editing information in association with the matching image identifier. When the editing information is already stored in association with the received image identifier, the editing information having the newer change date and time is stored in the photographed image table 600. Thus, the PC 103 can execute the image processing performed on the sub image corresponding to the captured image on the captured image by using the editing information.

  Even when the control unit 201 transmits the editing information to the PC 103 in S711, the control unit 201 transmits notification information for notifying the user that the editing information has been transmitted to the tablet 102 that is the transmission source of the editing information. Good. Furthermore, in this case, the tablet 102 displays the notification information on the display unit 307. This allows the user to confirm that the editing information has been sent.

  Next, in step S712, the control unit 201 determines whether end processing such as power off has been performed. When the end processing has been performed (YES in S712), the control unit 201 ends the information processing by the digital camera 101. If the termination process has not been performed (NO in S712), the control unit 201 advances the process to S703.

  Note that the digital camera 101 may receive editing information from the tablet 102 together with an image identifier identical to the image identifier transmitted to the PC 103 after transmitting the photographed image and the image identifier to the PC 103. Also in this case, the digital camera 101 transmits the editing information and the image identifier to the PC 103. Thereby, when the editing process is performed on the sub image in the tablet 102, the digital camera 101 appropriately transmits the editing information to the device (PC 103) of the transmission destination of the corresponding captured image as appropriate. be able to.

  As described above, in the photographing system 100 according to the present embodiment, when the digital camera 101 transmits the sub image to the tablet 102, the editing process is performed on the sub image in the tablet 102, the editing is performed. Receive editing information corresponding to the process. Then, when transmitting the captured image to the PC 103, the digital camera 101 transmits, to the PC 103, editing information related to the corresponding sub image. Thus, the editing information for the sub-image can be synchronized with the photographed image without requiring processing such as registration in the network for synchronization of the editing information. Further, by using the editing information, the PC 103 can reflect the image processing performed on the corresponding sub-image on the captured image. Further, the digital camera 101 stores the image identifier and the editing information even after deletion of the photographed image, and can transmit the editing information to the transmission destination of the photographed image. As described above, when the digital camera 101 transmits the corresponding first image and second image to different devices, and the destination device performs editing processing on the second image, it is troublesome. It is possible to reflect the editing process on the first image without requiring any process. That is, when transmitting a plurality of mutually related images to different devices, the digital camera 101 can appropriately manage the plurality of images without requiring complicated processing.

Second Embodiment
In the imaging system 100 according to the second embodiment, in the digital camera 101, the editing information and the image identifier are stored in the removable recording medium 204 in association with each other. Then, when the recording medium 204 is attached to the PC 103, the PC 103 reads the editing information and the image identifier from the recording medium 204. Thus, the PC 103 can acquire editing information corresponding to the already acquired photographed image. The differences between the imaging system 100 according to the second embodiment and the imaging system 100 according to the first embodiment will be mainly described below.

  FIG. 8 is a flowchart showing information processing by the digital camera 101 according to the second embodiment. Among the processes of the information processing illustrated in FIG. 8, the same processes as the processes of the information processing according to the first embodiment described with reference to FIG. 7 are denoted by the same reference numerals. After the process of S706, in S801, the control unit 201 receives from the tablet 102 the editing information associated with the image identifier in the captured image table 400 in S705, receives the editing information associated with the image identifier, and stores it in the recording medium 204. Do. Thereafter, the user disconnects the recording medium 204 from the digital camera 101 and connects it to the device IF of the PC 103. At this time, the PC 103 reads the editing information and the image identifier from the mounted recording medium 204. Then, the PC 103 searches the captured image table 600 for an image identifier that matches the read image identifier, and stores editing information in the captured image table 600 in association with the matched image identifier. Also in this case, the PC 103 stores editing information whose change date and time is new. The PC 103 further stores its own terminal identifier in the recording medium 204.

  Thereafter, when the recording medium 204 is attached to the digital camera 101 again, the control unit 201 of the digital camera 101 reads the terminal identifier stored in the recording medium 204 and stores the same in the transfer destination list 410 in S802. Then, the process proceeds to step S712. The remaining configuration and processing of the imaging system 100 according to the second embodiment are similar to the configuration and processing of the imaging system 100 according to the first embodiment.

  As described above, the imaging system 100 according to the second embodiment uses the removable recording medium, and without communicating with the PC 103, the imaging information of the editing result by the tablet 102 can be captured by the PC 103. It can be synchronized with the image.
