The camera image list display area 601 displays a list of reduced images of image files stored in the digital camera 101 acquired from the digital camera 101 by Wi-Fi communication.

  Since the acquisition of the reduced image requires only a very short time compared to the acquisition of the image file itself, even when a large amount of images are stored in the digital camera 101, the user can You can check the list quickly. The user can perform a tap operation on the reduced image and attach a plurality of selection check marks 602. When the import button 603 is tapped with one or more selection marks attached to the image, a selection image list XML is created, and an unreduced image file is acquired from the digital camera 101 according to the XML.

FIG. 7 is a diagram showing an example of a selected image list XML that shows a list of image files in the digital camera 101 selected by the user in the first embodiment.
The selected image list XML is generated by the digital camera 101 or the smartphone 111 in the following two situations.
One is a case where a user selects an image with the digital camera 101 before the digital camera 101 and the smartphone 111 perform NFC connection. In this case, the selected image list XML is generated on the digital camera 101 side and transmitted to the smartphone 111.

The other is a case where the user has not selected an image with the digital camera 101 before the digital camera 101 and the smartphone 111 perform NFC connection. In this case, the selected image list XML is generated on the smartphone 111 side according to the user's selection on the selection screen shown in FIG.
In the selected image list XML, in addition to the camera name 701 and the camera ID character string 702, a selected image file name 703 is described. The software that has received the selected image list XML requests the digital camera 101 for the file described in the selected image file name 703 and receives it.

The software list 801 includes a list of software installed in the smartphone 111 when the software status is acquired. Each software includes a software name 802, a software operation status 803, and a software status change time 804.

  In the example of FIG. 8A, the operation status 803 of the data reception software “CameraReceiver” for receiving an image from the digital camera 101 is “Active”, and the status change time 804 is “201411202000”. This indicates that the user is using the CameraReceiver software on the smartphone 111 from 20:00 on November 20, 2014.

  FIG. 8B shows an example in which the user starts using another software from 21:11 on November 20, 2014. Here, the status 811 of the software “CameraReceiver” is “Suspended”. This indicates that the user has not performed an operation, and it can be seen that the status was changed from the status change time 813 to 21:11 on November 20, 2014. At the same time, the status 812 of the software “Game” is “Active”, which indicates that the user is currently operating the “Game” software.

FIG. 9 is a flowchart for describing a processing procedure of the reception device from when the digital camera 101 and the smartphone 111 start NFC connection until the image transfer processing is completed in the first embodiment. This flowchart is realized by developing a program stored in the nonvolatile memory 208 in a work memory 207 functioning as a work memory, and the CPU 203 controlling each unit.
When the NFC connection between the digital camera 101 and the smartphone 111 is started, first, in step S <b> 901, the CPU 203 receives selection information XML as shown in FIG. 3 that is selection information of transmission target data from the NFC reader 113. When there is an image selection, a selection image list XML as shown in FIG. 7 may be received here.
In step S <b> 902, the CPU 203 analyzes the selection information XML and checks whether an image has been selected on the digital camera 101 side in advance. Specifically, the CPU 203 refers to the numerical value of the item of the number of selected images in the XML, and determines that selection is not performed if 0 and selection is performed if 1 or more. If the CPU 203 determines that a selection has been made, the process proceeds to S905. On the other hand, if it is determined that no selection has been made, the process proceeds to S903.

In step S903, the CPU 203 determines whether the connection status confirmation unit can be used on the smartphone 111 side. A process for determining whether or not to use the connection status checking means is performed. Details of this processing will be described later with reference to the flowchart of FIG.
In S904, if the connection status confirmation unit can be used, the CPU 203 proceeds to S905. If the connection status confirmation unit cannot be used, the CPU 203 returns to S903 and waits until the connection status confirmation unit can be used again.

  In step S905, Wi-Fi connection with the digital camera 101 is started. Here, a message indicating that the connection is being prepared for the user is displayed as shown in FIG. 4A or FIG. 5A, depending on the status of the data reception software at that time. At this time, the software status XML as shown in FIG. 8 is acquired.

In S906, the CPU 203 confirms from the selection information XML whether or not an image has been selected on the digital camera 101 side in advance, as in S902. If the CPU 203 determines that the selection has been made, the process proceeds to S910. If the CPU 203 determines that the selection has not been made, the process proceeds to S907.
In S907, after a reduced image of the stored image is acquired from the digital camera 101 by Wi-Fi connection, an image selection screen as shown in FIG. 6 is displayed in S908. Since the acquisition of the reduced image requires only a very short time compared to the acquisition of the image file itself, even when a large amount of images are stored in the digital camera 101, the user can You can check the list quickly.

When an image is selected on the image selection screen and the capture button 603 is tapped, a selection image list XML as shown in FIG. 7 is generated in S909, and the process proceeds to S911.
The processing from S907 to S909 is processing when the digital camera 101 has not performed image selection in advance. If selection has been performed in advance, in S910, the selected image list XML is acquired from the digital camera by Wi-Fi communication, and then the process proceeds to S911. That is, regardless of whether the digital camera 101 has selected an image in advance, a list of images that the user has selected to capture exists in the format of the selected image list XML in step S911.

  In S911, an image file is actually acquired by Wi-Fi communication according to the selected image list XML. Here, the user is in the process of acquiring an image as shown in FIG. 4B or 5B depending on the data reception status at that time. When the image transfer is completed, the Wi-Fi connection with the digital camera 101 is automatically disconnected in S912.

The processes from S913 to S916 are processes related to whether or not a disconnection notification is displayed to the user.
First, in S913, the software status XML as shown in FIG. 8 is acquired.
In step S914, the CPU 203 analyzes the software status XML and determines whether the user is using the data reception software. As a result of the determination, if it is in use, a disconnection notification as shown in FIG. 4C is displayed in S916.

  If the user is not using the data receiving software, in S915, the CPU 203 compares the software status XML acquired in S905 with the current software status XML. Here, during the connection with the digital camera 101, a disconnection notification determination process is performed to determine whether or not to perform disconnection notification depending on whether the user has used the smartphone 111 or not. If there is no difference between the two, the user determines that the software is not used during the reception of the image data by Wi-Fi, and in this case, it is not necessary to display a disconnection notification, and the process ends. . If there is a difference, it is determined that the user is using the smartphone 111, and in S916, the disconnection notification as shown in FIG.

  FIG. 10 is a diagram illustrating an example of screen output when the digital camera 101 and the smartphone 111 are NFC-connected in the first embodiment. This is displayed on the touch panel 205 in order to prompt the user to start the data reception software when the digital camera 101 has not performed image selection in advance. A data reception software validation message 1001 is displayed in the notification area, and the data reception software can be activated by tapping this message.

FIG. 11 is a flowchart showing the flow of the connection status confirmation unit availability determination process performed in S903 of FIG. 9 according to the first embodiment.
First, in S1101, the software status XML as shown in FIG. 8 is acquired.
In step S1102, the CPU 203 determines whether the user is using data reception software based on the software status XML. If it is determined that the data reception software is in use, the data reception software is displayed in the foreground, and therefore it is determined that the connection status can be confirmed, and the process returns to the process of FIG. If it is determined that it is not in use, the process proceeds to S1103, and the connection status confirmation is impossible after the notification that is the activation process of the connection status confirmation means for urging the data reception software to start as shown in FIG. It returns to the process of FIG.

  The user can start the data reception software by tapping the data reception software validation message 1001 on the screen of FIG. When activated, it can be determined that the connection status can be confirmed by performing the processing of FIG. 11 again. When the connection status checking means becomes available because it cannot be used, Wi-Fi connection processing is performed, and Wi-Fi connection with the digital camera 101 is started.
