Embodiments of the present invention will be described below with reference to the drawings.
[Basic configuration]

  Referring to FIG. 1, the content processing apparatus of the present invention is basically configured as follows. The first designation unit 1 designates one of one or more contents stored in the expansion device 6 having a transfer function and a storage function. The internal transfer request unit 2 requests the expansion device 6 to perform internal transfer of the content designated by the first designation unit 1. The first reproduction unit 3 reproduces the content transferred from the expansion device 6 in response to the request process of the internal transfer request unit 2. The first change request unit 4 requests the first designation unit 1 to change the designation destination in response to the first change operation. The first external transfer request unit 5 requests the expansion device 6 to transfer the content designated by the first designation unit 1 in response to the first transfer operation.

The content to be reproduced is changed in response to the change operation, and the reproduced content is transferred to the outside in response to the transfer operation. Accordingly, prior confirmation and selection of content to be transferred to the outside are possible, and operability related to external transfer of content stored in the expansion device 6 is improved.
[Example]

  The digital camera 10 shown in FIG. 2 is an example of a DPS device, and the expansion device 40 shown in FIG. 3 is an example of a DPS host. More specifically, the expansion device 40 is a detachable memory card having a wireless communication function. When the expansion device 40 is attached to the digital camera 10, the USB device 36 and the USB host 42 are connected to each other.

  When the camera mode is selected by the key input device 30 shown in FIG. 2, the following processing is executed under the imaging task. The camera CPU 28 instructs the driver 16 to repeat the exposure operation and the charge readout operation in order to execute the moving image capturing process under the imaging task. In response to a vertical synchronization signal Vsync that is periodically generated, the driver 16 exposes the imaging surface of the imager 14 and reads out the charges generated on the imaging surface in a raster scanning manner. From the imager 14, raw image data representing the object scene captured through the optical lens 12 is periodically output.

  The signal processing circuit 18 performs processing such as white balance adjustment, color separation, and YUV conversion on the raw image data output from the imager 14, and writes the generated YUV format image data to the SDRAM 22 through the memory control circuit 20. . The LCD driver 24 repeatedly reads out the image data stored in the SDRAM 22 through the memory control circuit 20 and drives the LCD monitor 26 based on the read image data. As a result, a through image representing the object scene is displayed on the monitor screen.

  When a recording operation is performed on the key input device 30, the camera CPU 28 creates an image file containing image data representing the object scene at the time of the operation in the SDRAM 22. Subsequently, the camera CPU 28 acquires the remaining capacity of the storage device 34 as “CAPeq1”, and determines whether or not the size of the created image file is smaller than the remaining capacity CAPeq1. If the size of the image file is equal to or larger than the remaining capacity CAPeq1, the camera CPU 28 stores the created image file in the storage device 34.

  On the other hand, if the size of the image file is smaller than the remaining capacity CAPeq1, the expansion device 40 is connected to the USB device 36, and the expansion device 40 can provide a service configuration suitable for the digital camera 10, and the size of the image file is The following processing is executed on condition that the remaining capacity CAPap1 is below.

  The camera CPU 28 first executes an SVC search process to determine whether or not the expansion device 40 can provide a service configuration suitable for the digital camera 10. Since the expansion device 40 can provide a service configuration suitable for the digital camera 10, the camera CPU 28 next performs an SVC capability determination process to acquire the remaining capacity of the storage device 50 provided in the expansion device 40 as “CAPap1”. Execute. Since the size of the image file is less than the remaining capacity CAPap1, the camera CPU 28 sets the job mode to “A” and executes “storage model 1”. As a result, the image file is stored in the storage device 50 of the expansion device 40.

  The SVC search process, the SVC capability determination process, and “storage model 1” will be described later.

  When the playback mode is selected by the key input device 30 with the expansion device 40 connected, the following processing is executed under the playback task. The camera CPU 28 executes SVC capability determination processing so as to obtain the total number of image files stored in the storage device 50 of the expansion device 40 as “Mmax”. The camera CPU 28 also acquires the total number of image files stored in the storage device 34 of the digital camera 10 as “Nmax”. The total number Nmax is set to the variable N, and the total number Mmax is set to the variable M.

  Subsequently, the camera CPU 28 reads out the image data stored in the Nth image file from the storage device 34 and develops the read out image data in the SDRAM 22. The developed image data is read by the LCD driver 24, and as a result, a corresponding reproduced image is displayed on the LCD monitor 26.

  When a feed operation is performed by the key input device 30, the camera CPU 28 decrements the variable N, and performs the same processing as described above, paying attention to the image file corresponding to the decremented variable N. As a result, another reproduced image is displayed on the LCD monitor 26. When a selection operation is performed by the key input device 30, the camera CPU 28 sets the job mode to “B” and executes “storage model 1”. As a result, the image file corresponding to the current reproduced image is transferred to the expansion device 40 and then transmitted to the external server 60 by the wireless LAN device 52.

  When the variable N is decreased to “0” by the sending operation, the camera CPU 28 executes “storage model 2_UP” in order to acquire the image data of the Mth image file stored in the storage device 50 of the expansion device 40. The acquired image data is developed in the SDRAM 22 and read out by the LCD driver 24 as described above. As a result, a corresponding reproduced image is displayed on the LCD monitor 26.

  When a feed operation is performed by the key input device 30, the camera CPU 28 decrements the variable M, and pays attention to the image file corresponding to the decremented variable M, and executes the same processing as described above. As a result, another reproduced image is displayed on the LCD monitor 26. When a selection operation is performed by the key input device 30, the camera CPU 28 sets the job mode to “C” and executes “storage model 2_LW”. As a result, image data corresponding to the current reproduced image is transmitted to the external server 60 by the wireless LAN device 52.

  Thus, the image file transmitted to the external server 60 corresponds to the image file stored in the SDRAM 22 of the digital camera 10 in the camera mode, and the storage device 34 of the digital camera 10 and the storage device of the expansion device 40 in the playback mode. This corresponds to the image files selected in order from 50. The difference from the prior art is that an image file can be selected from the storage device 50 of the expansion device 40.

  “Storage model 2_UP” and “storage model 2_LW” will be described later.

  Referring to FIG. 4, the camera CPU 28 of the digital camera 10 includes a communication client, a storage server, and a storage client in addition to the control module. The media CPU 44 of the expansion device 40 includes a communication server, a storage client, and a storage server in addition to the control module.

  More specifically, regarding the communication function, the media CPU 44 has a fixed role as a communication server, and the camera CPU 28 has a fixed role as a communication client. On the other hand, with regard to the storage function, the camera CPU 28 and the media CPU 44 have a role to play when “storage model 1” is executed and when “storage model 2_UP” and “storage model 2_LW” are executed. It is changed adaptively.

  That is, when “storage model 1” is executed, the camera CPU 28 serves as a storage server, while the media CPU 44 serves as a storage client. On the other hand, when “storage model 2_UP” and “storage model 2_LW” are executed, the media CPU 44 plays a role as a storage server, while the camera CPU 28 takes a role as a storage client.

Based on such division of roles, processing operations in each of the SVC search process, the SVC capability determination process, “storage model 1”, “storage model 2_UP”, and “storage model 2_LW” will be described below.
[SVC search processing]

  Referring to FIG. 5, the camera CPU 28 transmits a device search message. The transmitted device search message is given to the media CPU 44 via the USB device 36 and the USB host 42. In response to the device search message, the media CPU 44 returns a DPS host search message. The returned DPS host message is given to the camera CPU 28 via the USB host 42 and the USB device 36.

  The camera CPU 28 that has received the DPS host search message transmits a DPS_ConfigureCommService request describing the service configuration (specifically, service name and service version) of the digital camera 10 to the media CPU 44. The media CPU 44 acquires a service configuration (specifically, service name and service version) from the received DPS_ConfigureCommService request, and determines whether or not the acquired service configuration matches the service configuration of the expansion device 40.

  If the service configurations match, the media CPU 44 transmits a response (= ACK / Reply) to the DPS_ConfigureCommService request to the camera CPU 28. In ACK / Reply, the service configuration (specifically, the service name and service version) of the expansion device 40 is described. If the service configuration does not match, the ACK / Reply in which an error is described is sent to the camera CPU 28. Sent to.

The camera CPU 28 refers to the ACK / Reply description received from the media CPU 44 to determine whether the service configuration matches between the digital camera 10 and the expansion device 40. If the service configurations match, the camera CPU 28 considers that the expansion device 40 can provide a service configuration suitable for the digital camera 10.
[SVC capability judgment processing]

  Referring to FIGS. 6 and 7, the communication client of camera CPU 28 transmits a DPS_GetCommSvcCapability request in which “capacity” or “number of files” is described as a parameter to media CPU 44.

  When the parameter described in the DPS_GetCommSvcCapability request is “capacity”, the communication server of the media CPU 44 accesses the storage device 50 via the control module, acquires the total capacity and remaining capacity of the storage device 50 as storage information, Then, ACK / Reply in which the acquired storage information is described is returned to the communication client.

On the other hand, when the parameter described in the DPS_GetCommCapability request is “number of files”, the communication server of the media CPU 44 accesses the storage device 50 via the control module and stores the image file stored in the storage device 50. The total number is acquired as storage information, and ACK / Reply in which the acquired storage information is described is returned to the communication client. The storage information described in ACK / Reply is extracted by the communication client of the camera CPU 28.
[Storage model 1]

  Referring to FIGS. 8 and 9, the communication client of camera CPU 28 transmits a DPS_CommStartJob request describing the job mode “A” or “B” to the communication server of media CPU 44.

  The communication server of the media CPU 44 transmits a response (= ACK) to the DPS_CommStartJob request to the communication client. In addition, the control module of the media CPU 44 transmits a DPS_GetFileInfo request to the storage server of the camera CPU 28.

  The storage server of the camera CPU 28 acquires file information in response to the DPS_GetFileInfo request. The acquired file information is file information of an image file newly created in response to a recording operation when the job mode is “A”. The acquired file information is also file information of the Nth image file stored in the storage device 34 when the job mode is “B”. The storage server of the camera CPU 28 transmits ACK / Reply in which the acquired file information is described to the storage client of the media CPU 44.

  The storage client of the media CPU 44 transmits a DPS_GetFile request to the storage server of the camera CPU 28 in response to ACK / Reply.

  The storage server of the camera CPU 28 acquires an image file in response to the DPS_GetFile request, and transmits the acquired image file to the storage client of the media CPU 44. The transmitted image file is a newly created image file when the job mode is “A”, and the Nth image file saved in the storage device 34 when the job mode is “B”.

  The received image file is stored in the SDRAM 48 by the memory control circuit 46. The media CPU 44 executes different processes according to the job mode as follows.

  If the job mode is “A”, the storage client stores the image file stored in the SDRAM 48 in the storage device 50 via the control module. When the storage process is completed, a DPS_NotifyCommStatus request is transmitted from the communication server of the media CPU 44 to the communication client of the camera CPU 28.

If the job mode is “B”, the control module issues a data transfer request to the storage client of the media CPU 44 and acquires the image data of the image file stored in the SDRAM 48. The acquired image data is transmitted to the external server 60 by the wireless LAN device 52. When the image data transfer process (image data acquisition process) is completed, the communication server transmits a DPS_NotifyCommStatus request to the communication client of the camera CPU 28.
[Storage model 2_UP]

  Referring to FIG. 10, the storage client of camera CPU 28 transmits a DPS_GetMediaInfo request to media CPU 44 when a sending operation is executed. The storage server of the media CPU 44 acquires image information from the storage device 50 in response to the DPS_GetMediaInfo request, and transmits ACK / Reply in which the acquired image information is described to the camera CPU 28.

The storage client of the camera CPU 28 extracts image information from the received ACK / Reply and transmits a DPS_GetMediaData request to the media CPU 44. The storage server of the media CPU 44 expands the image data of the image file stored in the storage device 50 in response to the DPS_GetMediaData request to the SDRAM 48 through the memory control circuit 46, and transmits ACK / Reply including the expanded image data to the camera CPU 28. Send to.
[Storage model 2_LW]

  Referring to FIG. 11, the communication client of camera CPU 28 transmits a DPS_CommStartJob request to media CPU 44 when the selection operation is executed. The communication server of the media CPU 44 returns an ACK in response to the DPS_CommStartJob request, and issues a data transfer request to the storage server of the media CPU 44 in order to acquire image data from the SDRAM 48. The acquired image data is transmitted to the external server 60 by the wireless LAN device 52. When the data transfer process (image data acquisition process) is completed, the storage server of the media CPU 44 transmits a DPS_NotifyCommStatus request to the camera CPU 40.

  The camera CPU 28 provided in the digital camera 10 executes the imaging task shown in FIGS. 12 to 13 corresponding to the camera mode, and executes the reproduction task shown in FIGS. 14 to 16 corresponding to the reproduction mode. Note that control programs corresponding to these tasks are stored in the flash memory 38.

  Referring to FIG. 12, in step S1, a moving image capturing process is executed. As a result, a through image is displayed on the LCD monitor 26. In step S3, it is determined whether or not a recording operation has been performed. If the determination result is updated from NO to YES, an image file creation process is executed in step S5. As a result, an image file containing image data representing the scene at the time when the recording operation is performed is created in the SDRAM 22.

  In step S7, the remaining capacity of the storage device 34 is acquired as “CAPeq1”. In step S9, it is determined whether or not the size of the image file created in step S5 is smaller than the remaining capacity CAPeq1 acquired in step S7. If the determination result is YES, the process proceeds to step S11, and the image file created in step S5 is recorded in the storage device 34. When the recording process is completed, the process returns to step S3.

  If the determination result in step S9 is NO, it is determined in step S13 whether or not the expansion device 40 is connected to the USB device 36. If the expansion device 40 is not connected to the USB device 36, a storage error is notified in step S27, and then the process returns to step S3. If the expansion device 40 is connected to the USB device 36, an SVC search process is executed in step S15. In step S17, it is determined based on the result of the SVC search process whether or not the expansion device 40 can provide a service configuration suitable for the digital camera 10.

  If a determination result is NO, it will return to step S3 through the alerting | reporting process of step S27. If the determination result is YES, an SVC capability determination process is executed in step S19 in order to acquire the remaining capacity of the storage device 50 provided in the expansion device 40 as “CAPap1”.

  In step S21, it is determined whether or not the size of the image file created in step S5 is smaller than the remaining capacity CAPap1 acquired in step S19. If a determination result is NO, it will return to step S3 through the alerting | reporting process of step S27. If the determination result is YES, the job mode is set to “A” in step S23, and “storage model 1” is executed in step S25. When the process of step S25 is completed, the process returns to step S3.

  Referring to FIG. 14, in steps S31 to S35, the same processes as in steps S13 to S17 described above are executed. If the determination result in step S31 or S35 is NO, a transmission error is notified in step S37, and then the process returns to step S31.

  If “YES” in the step S35, the SVC capability determining process is executed in a step S39 so as to obtain the total number of image files stored in the storage device 50 of the expansion device 40 as “Mmax”. In step S41, the total number of image files stored in the storage device 34 of the digital camera 10 is acquired as “Nmax”.

  In step S43, it is determined whether or not the total number Nmax is “0”. If the determination result is YES, the process proceeds to step S63. If the determination result is NO, the total number Nmax is set to the variable N in step S45. In step S47, it is determined whether or not the variable N exceeds “0”. If the determination result is NO, the process proceeds to step S63, and if the determination result is YES, the process proceeds to step S49.

  In step S49, the image data stored in the Nth image file is read from the storage device 34, and the read image data is developed in the SDRAM 22. The developed image data is read by the LCD driver 24, and as a result, a corresponding reproduced image is displayed on the LCD monitor 26.

  In step S51, it is determined whether or not a feed operation has been performed by the key input device 30, and in step S53, it is determined whether or not a selection operation has been performed by the key input device 30. If the decision result in the step S51 is YES, the variable N is decremented in a step S55, and thereafter, the process returns to the step S47. If the decision result in the step S53 is YES, the job mode is set to “B” in a step S57, “storage model 1” is executed in a step S59, and then the process returns to the step S51.

  In step S63, it is determined whether or not the total number Mmax is “0”. If the determination result is YES, the process returns to step S43. If the determination result is NO, the total number Mmax is set to the variable M in step S65. In step S67, it is determined whether or not the variable M exceeds “0”. If the determination result is NO, the process returns to step S43, whereas if the determination result is YES, the process proceeds to step S69.

  In step S69, “storage model 2_UP” is executed in order to acquire the Mth image file stored in the storage device 50 of the expansion device 40. In step S71, the image data stored in the acquired image file is developed in the SDRAM 22. As a result, a corresponding reproduced image is displayed on the LCD monitor 26.

  In step S73, it is determined whether or not a feed operation has been performed by the key input device 30, and in step S75, it is determined whether or not a selection operation has been performed by the key input device 30. If the decision result in the step S73 is YES, the variable M is decremented in a step S77, and thereafter, the process returns to the step S67. If the decision result in the step S75 is YES, the job mode is set to “C” in a step S79, “storage model 2_LW” is executed in a step S81, and then the process returns to the step S73.

  The SVC search process in step S15 shown in FIG. 13 or step S33 shown in FIG. 14 is executed according to a subroutine shown in FIG. First, in step S91, a device search message is transmitted. In step S93, it is determined whether a DPS host search message has been received from the expansion device 40, and in step S95, it is determined whether a timeout has occurred.

  If a timeout occurs without receiving the DPS host search message, YES is determined in step S95, a service error is notified in step S109, and the process returns to the upper layer routine. If a DPS host search message is received before a timeout occurs, YES is determined in step S93, and an initialization operation is executed in step S97. As a result, a DPS_ConfigureCommService request describing the service configuration (specifically, service name and service version) of the digital camera 10 is transmitted to the expansion device 40.

  In step S99, it is determined whether or not an ACK / Reply has been received from the expansion device 40. In step S101, it is determined whether or not a timeout has occurred. If a timeout occurs without receiving ACK / Reply, YES is determined in step S101, and the process returns to the upper-level routine through the notification process in step S109.

  If ACK / Reply is received before the timeout occurs, YES is determined in step S99, and it is determined in step S103 whether or not the service configuration matches between the digital camera 10 and the expansion device 40. The ACK / Reply received from the expansion device 40 describes the service configuration of the expansion device 40 (specifically, the service name and service version). In the determination process in step S103, this service configuration is referred to.

  If the determination result in step S103 is NO, the process returns to the upper hierarchy routine through the notification process in step S109. If the determination result in step S103 is YES, it is determined in step S105 whether a DPS_NotifyCommStatus request has been received from the expansion device 40, and whether a timeout has occurred is determined in step S107.

  If a DPS_NotifyCommStatus request is received before the timeout occurs, YES is determined in step S105, a communication error is notified in step S111, and the process returns to the upper layer routine. On the other hand, if a timeout occurs without receiving the DPS_NotifyCommStatus request, it is assumed that the expansion device 40 can provide a service configuration suitable for the digital camera 10, and the process returns to the upper layer routine without notifying an error. To do.

  The SVC capability determination process in step S19 shown in FIG. 13 or step S39 shown in FIG. 14 is executed according to a subroutine shown in FIGS. In step S121, it is determined whether the capacity to be determined is “capacity” or “number of files”, and the process proceeds to step S123 corresponding to “capacity”, while the process proceeds to step S137 corresponding to “number of files”. move on.

  Note that the processing after step S123 is executed when the routine proceeds from step S19 shown in FIG. 13 to this subroutine. Further, the processing after step S137 is executed when the subroutine proceeds from step S39 shown in FIG.

  In step S123, an initialization operation is executed. As a result, a DPS_GetCommSvcCapability request describing “capacity” as a parameter is transmitted to the expansion device 40. In step S125, it is determined whether or not ACK / Reply has been received from the expansion device 40, and in step S127, it is determined whether or not a timeout has occurred. If a time-out occurs without receiving ACK / Reply, YES is determined in step S127, a communication error is notified in step S135, and the process returns to the upper layer routine.

  If ACK / Reply is received before timeout occurs, the process proceeds from step S125 to step S129, and the storage information described in ACK / Reply (specifically, the total capacity and remaining capacity of the storage device 50) is extracted.

  In step S131, it is determined whether a DPS_NotifyCommStatus request has been received from the expansion device 40, and in step S133, it is determined whether a timeout has occurred. If the DPS_NotifyCommStatus request is received before the timeout occurs, YES is determined in step S131, and the process returns to the upper hierarchy routine through the notification process in step S135. On the other hand, if a timeout occurs without receiving a DPS_NotifyCommStatus request, the process returns to the upper layer routine.

  In steps S137 to S149, processing similar to that in steps S123 to S135 described above is executed. The difference is that the parameter described in the DPS_GetCommSvcCapability request transmitted in step S137 is “number of files” and the storage information extracted from ACK / Reply in step S143 is the image file stored in the storage device 50. It is a point that is the total number.

  “Storage model 1” in step S25 shown in FIG. 13 or step S59 shown in FIG. 15 is executed according to the subroutine shown in FIGS. First, in step S151, a DPS_CommStartJob request is transmitted to the expansion device 40. In this request, the job mode set in step S23 or S57 is described.

  In step S153, it is determined whether or not an ACK has been received. In step S155, it is determined whether or not a timeout has occurred. If a timeout occurs without receiving an ACK, YES is determined in step S155, a communication error is notified in step S191, and the process returns to the upper layer routine. If ACK is received before the timeout occurs, the process proceeds from step S153 to step S157.

  In step S157, it is determined whether a DPS_NotifyCommStatus request has been received from the expansion device 40, and in step S159, it is determined whether a timeout has occurred. If a DPS_NotifyCommStatus request is received before the timeout occurs, YES is determined in step S157, and the process returns to the upper layer routine through the notification process in step S191. If a timeout occurs without receiving a DPS_NotifyCommStatus request, the process advances from step S159 to step S161.

  In step S161, it is determined whether a DPS_GetFileInfo request has been received from the expansion device 40, and in step S163, it is determined whether a timeout has occurred. If a timeout occurs before receiving the DPS_GetFileInfo request, YES is determined in step S163, and the process returns to the upper hierarchy routine through the notification process in step S191. If the DPS_GetFileInfo request is received before the timeout occurs, the process proceeds from step S161 to step S165.

  In step S165, file information is acquired. When the process proceeds from step S25 shown in FIG. 13 to this subroutine, the file information of the image file created in step S5 shown in FIG. 12 is acquired. When the process proceeds from step S59 shown in FIG. 15 to this subroutine, file information of the Nth image file stored in the storage device 34 is acquired. In step S167, a response to the received DPS_GetFileInfo request is transmitted to the expansion device 40. The file information acquired in step S165 is described in the response to be transmitted.

  In steps S169 to S171, processing similar to that in steps S157 to S159 described above is executed. If “YES” in the step S169, the process returns to the upper hierarchy routine through the notification process of the step S191, and if “YES” in the step S171, the process proceeds to the step S173.

  In step S173, it is determined whether a DPS_GetFile request has been received from the expansion device 40, and in step S175, it is determined whether a timeout has occurred. If a timeout occurs before receiving the DPS_GetFile request, YES is determined in step S175, and the process returns to the upper-level routine through the notification process in step S191. If the DPS_GetFile request is received before the timeout occurs, the process proceeds from step S173 to step S177.

  In step S177, an image file is acquired. When the process proceeds from step S25 shown in FIG. 13 to this subroutine, the image file created in step S5 shown in FIG. 12 is acquired. Further, when the process proceeds from step S59 shown in FIG. 15 to this subroutine, the Nth image file saved in the storage device 34 is acquired. In step S179, the acquired image file is transmitted to the expansion device 40.

  In step S181, it is repeatedly determined whether or not the transmission of the image file is completed. When the determination result is updated from NO to YES, ACK is transmitted to the expansion device 40 in step S183.

  In step S185, it is determined whether a DPS_NotifyCommStatus request has been received from the expansion device 40, and in step S187, it is determined whether a timeout has occurred. If a DPS_NotifyCommStatus request is received before the timeout occurs, YES is determined in step S185, communication completion is notified in step S189, and the process returns to the upper layer routine. If a timeout occurs without receiving a DPS_NotifyCommStatus request, the process returns to the upper layer routine through the notification process in step S191.

  “Storage model 2_UP” in step S69 shown in FIG. 16 is executed according to a subroutine shown in FIG. First, an initialization operation is executed in step S201. As a result, the DPS_GetMediaInfo request is transmitted toward the expansion device 40. In step S203, it is determined whether or not ACK / Reply has been received from the expansion device 40. In step S205, it is determined whether or not a timeout has occurred.

  If a timeout occurs without receiving ACK / Reply, YES is determined in step S205, a communication error is notified in step S219, and the process returns to the upper-level routine. If ACK / Reply is received before timeout occurs, the process proceeds from step S203 to step S207, and image information is extracted from the received ACK / Reply.

  When the extraction of the image information is completed, an initialization operation is executed in step S209. As a result, the DPS_GetMediaData request is transmitted toward the expansion device 40. In steps S211 to S213, processing similar to that in steps S203 to S205 described above is executed. If “YES” in the step S213, the process returns to the upper hierarchy routine through the notification process of the step S219.

  If “YES” in the step S211, the process proceeds to a step S215 to extract image data from the received ACK / Reply. In step S217, it is determined whether or not the extraction of all image data has been completed. If NO, the process returns to step S215. If YES, the process returns to the upper hierarchy routine.

  “Storage model 2_LW” in step S81 shown in FIG. 16 is executed according to the subroutine shown in FIG. First, in step S221, an initialization operation is executed. As a result, a DPS_CommStartJob request is transmitted toward the expansion device 40. In step S223, it is determined whether or not an ACK has been received from the expansion device 40. In step S225, it is determined whether or not a timeout has occurred.

  If a timeout occurs without receiving an ACK, YES is determined in step S225, a communication error is notified in step S233, and the process returns to the upper layer routine. If ACK is received before the timeout occurs, the process proceeds from step S223 to step S227.

  In step S227, it is determined whether a DPS_NotifyCommStatus request is received from the expansion device 40, and in step S229, it is determined whether a timeout has occurred. If a DPS_NotifyCommStatus request is received before the timeout occurs, YES is determined in step S227, communication completion is notified in step S231, and the process returns to the upper layer routine. If a timeout occurs without receiving a DPS_NotifyCommStatus request, the process returns to the upper-level routine through the notification process in step S233.

  The media CPU 44 provided in the expansion device 40 executes processing according to the flowcharts shown in FIGS. A control program corresponding to this flowchart is stored in the flash memory 54.

  Referring to FIG. 25, in step S241, it is determined whether or not a DPS device (digital camera 10 in this embodiment) connected to USB host 42 has been found. If the determination result is YES, the process proceeds to step S253, and if the determination result is NO, the process proceeds to step S243.

  In step S243, it is determined whether a device search message has been received from the DPS device. In step S245, it is determined whether a timeout has occurred. If a timeout occurs before receiving the device search message, YES is determined in step S245, and the process is terminated.

  If the device search message is received before the timeout occurs, the process proceeds from step S243 to step S247, and the DPS host search message is transmitted to the DPS device. In step S249, the communication server recognizes the discovery of the DPS device, and in step S251, the control module recognizes the discovery of the DPS device. When the process of step S251 is completed, the process proceeds to step S253.

  In step S253, it is determined whether a DPS_ConfigureCommService request has been received from the DPS device. In step S255, it is determined whether the service configuration of the DPS device has been acquired. If the determination result of step S253 is YES, it will progress to step S259, and if the determination result of step S255 is YES, it will progress to step S271. If the determination results in steps S253 and S255 are NO, an ACK describing an error is transmitted to the DPS device in step S257, and the process returns to step S253.

  In step S259, the service configuration (specifically, service name and service version) described in the DPS_ConfigureCommService request is acquired. In step S261, it is determined whether or not the acquired service configuration matches the service configuration of the expansion device 40. If the determination result is YES, the process proceeds to step S263, and if the determination result is NO, the process proceeds to step S267.

  In step S263, the control module recognizes the success of the search process, and in step S265, a response to the DPS_ConfigureCommService request is transmitted to the DPS device. In the response, the service configuration (specifically, the service name and service version) of the expansion device 40 is described. When the processing in step S265 is completed, the process proceeds to step S271.

  In step S267, the control module recognizes the failure of the search process, and in step S269, a response process to the DPS_ConfigureCommService request is executed. An error is described in the response. When the process of step S269 is completed, the process proceeds to step S253.

  In step S271, it is determined whether a DPS_GetCommSvcCapability request has been received from the DPS device. If the determination result is NO, the process proceeds to step S285, while if the determination result is YES, the process proceeds to step S273.

  In step S273, the parameter described in the received DPS_GetCommSvcCapability request is acquired. In step S275, it is determined whether the acquired parameter is “capacity” or “number of files”. If the parameter is “capacity”, the process proceeds to steps S285 through steps S277 to S279, and if the parameter is “number of files”, the process proceeds to steps S285 through steps S281 to S283.

  In step S277, the total capacity and remaining capacity of the storage device 50 are acquired as storage information, and in step S279, a response process to the DPS_GetCommSvcCapability request is executed. In the response, the storage information (total capacity and remaining capacity) acquired in step S277 is described.

  In step S281, the total number of image files stored in the storage device 50 is acquired as storage information. In step S283, a response process to the DPS_GetCommSvcCapability request is executed. In the response, the storage information (total number of files) acquired in step S277 is described.

  In step S285, it is determined whether a DPS_CommStartJob request has been received from the DPS device. If the determination result is YES, the process proceeds to step S287, and if the determination result is NO, the process proceeds to step S329. In step S287, response processing to the DPS_CommStartJob request is executed, and in step S289, it is determined whether or not the job mode described in the DPS_CommStartJob request is “C”. If the determination result is YES, the process proceeds to step S291, and if the determination result is NO, the process proceeds to step S299.

  In step S291, a data transfer request is issued to the storage server of the expansion device 40, and image data is acquired from the storage device 34 in step S293. The acquired image data is transmitted to the external server 60 by the wireless LAN device 52. In step S295, it is determined whether or not the data transfer is completed. If the determination result is updated from NO to YES, the process proceeds to step S297. In step S297, an initialization operation is executed, whereby a DPS_NotifyCommStatus request is transmitted to the DPS device. When the initialization operation is completed, the process returns to step S271.

  In step S299, an initialization operation is executed to transmit a DPS_GetFileInfo request to the DPS device. In step S301, it is determined whether or not ACK / Reply has been received from the DPS device. In step S303, it is determined whether or not a timeout has occurred. If a timeout occurs before receiving ACK / Reply, YES is determined in step S303, and an initialization operation is executed in step S315. With the initialization operation, a DPS_NotifyCommStatus request is transmitted toward the DPS device. When the initialization operation is completed, the process returns to step S271.

  If ACK / Reply is received before the timeout occurs, YES is determined in step S305, and an initialization operation is executed in step S305. As a result, a DPS_GetFile request is transmitted to the DPS device.

  In step S307, it is determined whether an image file has been received from the DPS device. In step S309, it is determined whether a timeout has occurred. If a timeout occurs before receiving the image file, the process returns to step S271 through step S315. If the image file is received before the timeout occurs, the process proceeds to step S311.

  In step S311, it is determined whether or not an ACK has been received from the DPS device. In step S313, it is determined whether or not a timeout has occurred. If a timeout occurs before ACK is received, the process returns to step S271 through step S315. If an ACK is received before the timeout occurs, the process proceeds to step S317.

  In step S317, it is determined whether or not the job mode described in the DPS_CommStartJob request received in step S285 is “B”. If the determination result is YES, the process proceeds to step S319, and if the determination result is NO, the process proceeds to step S325.

  In step S319, a data transfer request is issued to the storage client of the expansion device 40. In step S321, image data is acquired from the SDRAM 48. The acquired image data is then transmitted to the external server 60 by the wireless LAN device 52. In step S323, it is determined whether or not the transfer of the image data has been completed. When the determination result is updated from NO to YES, an initialization operation is executed in step S327 to transmit a DPS_NotifyCommStatus request to the DPS device. When the initialization operation is completed, the process returns to step S271.

  If “NO” in the step S317, the job mode is regarded as “A”, and the process proceeds to the step S325. In step S325, the image file received from the DPS device is stored in the storage device 50. When the storage process is completed, the process returns to step S271 through the initialization operation in step S327.

  In step S329, it is determined whether a DPS_GetMediaInfo request has been received from the DPS device. In step S331, it is determined whether a DPS_GetMediaData request has been received from the DPS device. If “YES” in the step S329, the process returns to the step S271 through the processes of the steps S333 to S335, and if “YES” in the step S331, the process returns to the step S271 through the processes of the steps S337 to S339, and both the steps S329 and S331 are NO. If it is, the process returns to step S271.

  In step S333, image information is acquired from the storage device 50, and in step S335, response processing to the DPS_GetMediaInfo request is executed. The acquired image information is transmitted to the DPS device by response processing. In step S337, image data is acquired from the storage device 50. In step S339, a response process to the DPS_GetMediaInfo request is executed. The acquired image data is transmitted to the DPS device by response processing.

  As can be seen from the above description, the expansion device 40 has a transfer function and a storage function. The camera CPU 26 designates one of one or more images stored in the expansion device 40 (S65, S77), and requests the expansion device 40 to transfer the designated image internally (S69, S201, S209). . When the designated image is transferred from the expansion device 40, the camera CPU 26 reproduces the transferred image on the LCD monitor 26 (S71). The camera CPU 26 also changes the designated image in response to the feed operation (S73), and requests the expansion device 40 to transfer the designated image in response to the selection operation (S75, S79, S81, S221).

  In this way, the image to be reproduced is changed in response to the sending operation, and the reproduced image is transferred to the outside in response to the selection operation. Thus, prior confirmation and selection of images to be transferred to the outside are possible, and operability related to external transfer of images stored in the expansion device 40 is improved.
