  In FIG. 1, a digital camera has been described as an example of a wireless terminal device. However, the present invention is not limited to this, and for example, a terminal device having a wireless function such as a PDA or a smartphone may be used.

  FIG. 2 shows a flowchart showing the operation of the wireless terminal device as the transmission source in the first embodiment. Hereinafter, it demonstrates according to a flowchart.

  In step S201, the data stored in the memory card 9 is displayed on the display unit 15, and the user uses the operation unit 14 to select an image to be transferred. When the selection is completed, the process proceeds to step S202.

  In S202, when the user presses a wireless button included in the operation unit 14, the screen shifts to a menu for wirelessly transferring an image. The location of the wireless button is not limited to this. For example, when the display unit 15 is a touch panel, it may be provided as an icon button in the display area.

  In step S203, power supply to the wireless communication unit 20 is started and communication with the CPU 19 is started.

  In step S204, battery remaining amount information of each wireless terminal device that is a connection target is acquired. As shown in FIG. 3, the wireless terminal device 30 that is the transmission source acquires the remaining battery levels of the wireless terminal devices 301 to 304 that are waiting for reception.

  At this time, the acquisition order of the remaining battery level is, for example, the registration order of the terminal information stored in the setting value recording memory 18 of the wireless terminal device 30 that is the transmission source as shown in FIG. It is done.

  After obtaining the remaining battery level, in step S205, the terminal name and its remaining battery level are displayed together on the display unit 15 of the terminal device 30 as the transmission source as shown in FIG.

  In step S206, the user selects an image data transfer mode. The transfer mode is selected by the user from either “individual transfer” or “relay transfer” from the screen displayed on the display unit 15 as shown in FIG.

  The individual transfer is a mode in which the wireless terminal device 30 as a transmission source transfers to the wireless terminal devices 301 to 304 one by one as shown in FIG. 6 (a).

  On the other hand, the relay transfer is a mode in which image data is transferred in a relay format from one of the terminals 301 to 304 waiting for reception from the wireless terminal device 30 as a transmission source as shown in FIG. 6 (b).

  In the case of individual transfer, since the transmission source wireless terminal device transfers image data one by one, the battery consumption of the transmission source wireless terminal device 30 is larger than the battery consumption of the wireless terminal device waiting for reception.

  On the other hand, in the case of relay transfer, since the wireless terminal device of the transmission source is changed by the relay method, the battery consumption of the wireless terminal device of the transmission source is significantly larger than the battery consumption of other wireless terminal devices. Absent.

  If relay transfer is selected by the user in S206, the process proceeds to step S207.

  In S207, as shown in FIG. 7, a terminal with a large remaining battery capacity is displayed on the display unit 15 as a connection destination candidate list.

  The number of displays of the connection destination candidate list can be changed depending on the remaining battery level of the wireless terminal as the transmission source. For example, when the remaining battery level of the transmission source wireless terminal is large, a plurality of connection destinations are listed as candidates. On the other hand, when the remaining battery level is small, a single candidate is selected.

  In step S208, the user of the wireless terminal device 30 that is the transmission source selects a transfer destination from those displayed on the display unit 15 as shown in FIG. 7, and transmits the image data in step S209. When the image data is transferred in S209, the information on the terminal to be transferred next by the receiver is also transferred.

  In step S210, it is confirmed whether or not the image data has been transferred to all of the connection destination candidate lists. If the transfer has not been completed for all, the process returns to S209 to transfer the image to the remaining transfer destinations.

  On the other hand, if the transfer has been completed for all, the process proceeds to step S211 where the power of the wireless communication unit is turned off and all the processes are ended.

  If individual transfer is selected in S206, the process proceeds to step S212.

  In S212, the wireless terminal device 30 as the transmission source transfers the image data one by one to the wireless terminal device waiting for reception. When the transfer of the image data to all the wireless terminal devices is completed, the process proceeds to S211 to turn off the power of the wireless communication unit and end all the processes.

  Next, FIG. 8 shows a flowchart showing the operation of the wireless terminal device 301 waiting for reception in the first embodiment. Hereinafter, it demonstrates according to a flowchart.

  In step S801, image data is received from the source wireless terminal device 30.

  In step S802, after the next transfer destination is selected from those displayed as shown in FIG. 9, in step S803, the wireless terminal device 301 checks the remaining battery level of the next transfer destination wireless terminal device.

  If it is determined in S803 that the remaining battery level of the wireless terminal device of the next transfer destination is sufficient, the process proceeds to step S804 and the image is transferred to the next transfer destination. In step S805, it is confirmed whether or not the image transfer has been completed. If all the images have been transferred, the process ends.

  On the other hand, if it is determined in S803 that the remaining battery level of the wireless terminal device of the next transfer destination is not sufficient, the process proceeds to step S806 to make an image transfer reservation. In this embodiment, the wireless terminal device 301 makes a transfer reservation to the wireless terminal device 303, and all the processes are completed.

  As described above, it is possible to reduce the concentration of the power load on the transmission source wireless terminal device by performing control so that the transmission source wireless terminal device is changed by the relay method.
