The process of FIG. 3 is performed by the control unit 103 executing the communication control program stored in the non-volatile memory 105, and it is premised that the communication control application is started. When the communication control application is activated, the setting menu 400 of FIG. 4A is displayed on the display unit 108 on the mobile terminal 101. The setting menu 400 is a menu image for instructing the execution of the display processing of the captured image for displaying each information of the plurality of captured images stored in the digital camera 102 on the display unit 108, and is the menu image for instructing the execution of the display processing of the captured image. An operation button 401 for instructing execution is provided.

In FIG. 3, first, the mobile terminal 101 detects that the operation button 401 of the setting menu 400 displayed on the display unit 108 is selected by the user (timing T301). Next, the mobile terminal 101 transmits a list request notification requesting list information of the captured images stored in the digital camera 102 to the digital camera 102 (timing T302). Next, the mobile terminal 101 receives the list information transmitted from the digital camera 102 in response to the list request notification (timing T303). The list information includes a plurality of image identification IDs for identifying each of the plurality of captured images stored in the digital camera 102.

Next, the mobile terminal 101 transmits to the digital camera 102 a data request notification requesting the header information of the photographed images of the standard display number and the thumbnail images of the standard display number set in advance based on the received list information ( Timing T304). Each header information includes information such as the data format and resolution of each captured image, and is associated with each thumbnail image. Next, the mobile terminal 101 receives the number of header information and thumbnail images corresponding to the data request notification from the digital camera 102 (timing T305). Next, the mobile terminal 101 displays a list of the plurality of received thumbnail images on the display unit 108 (timing T306). After that, the mobile terminal 101 generates a plurality of attribute icons in association with each thumbnail image based on each received header information. The plurality of attribute icons are the file format of the captured image, the resolution of the captured image, information indicating whether or not the captured image is stored in the mobile terminal 101, and the contents of the attribute icons generated for each thumbnail image. The number is different.

Next, the mobile terminal 101 superimposes an attribute icon on each thumbnail image and displays it (timing T307). For example, at the timing T307, the attribute icons 404a to 404c associated with the thumbnail image 403 are displayed superimposed on the thumbnail image 403 as shown in the list image 402 of FIG. 4B. The attribute icons 404a to 404c are displayed in predetermined display sizes at the four corners and both ends of the thumbnail image 403 so that the thumbnail image 403 is not difficult to see. As a result, the user can confirm each information of the captured image stored in the digital camera 102 by using the mobile terminal 101.

By the way, the mobile terminal 101 detects a pinch operation of the display unit 108 of the user or an operation of a slider (not shown) displayed on the display unit 108, and receives a reduction instruction or an enlargement instruction of the thumbnail image, and adjusts the operation amount of each operation. Set the degree of reduction and enlargement accordingly. In the present embodiment, the case where the thumbnail image reduction instruction is received will be described at timings T308 to T315 described later, and the case where the thumbnail image enlargement instruction is received will be described at timings T316 to T323 described later.

Upon receiving the thumbnail image reduction instruction (timing T308), the mobile terminal 101 determines the thumbnail image display size and the number of thumbnail images to be displayed according to the set reduction width (timing T309). Here, from the viewpoint of the visibility of the attribute icon, it is preferable that the mobile terminal 101 does not change the display size of the attribute icon from the predetermined display size (first correspondence) when the thumbnail image reduction instruction is given. .. Further, from the viewpoint of preventing erroneous recognition by the user, when a thumbnail image reduction instruction is given, the mobile terminal 101 performs a process of missing some information about the captured image, specifically, only some attribute icons. It is preferable not to perform a process such as deleting (second correspondence). However, if both the first correspondence and the second correspondence are realized when the thumbnail image reduction instruction is given, the display unit 108 covers the thumbnail image with the attribute icon as the display size of the thumbnail image becomes smaller. The area to be covered will increase. As a result, the thumbnail image becomes difficult to see. Correspondingly, the mobile terminal 101 determines the specification of the display of the attribute icon based on the determined display size of the thumbnail image. Specifically, the mobile terminal 101 determines whether or not to display the attribute icon based on the determined display size of the thumbnail image (timing T310). At the timing T310, when the display size of the thumbnail image determined at the timing T309 is smaller than the preset first size, the mobile terminal 101 determines not to display the attribute icon. The first size is the display size of the thumbnail image so that the attribute icons do not overlap each other even if the associated attribute icons are displayed at the four corners or both ends of the thumbnail image in all the thumbnail images. On the other hand, when the display size of the thumbnail image determined at the timing T309 is equal to or larger than the preset first size, the mobile terminal 101 determines to display the attribute icon.

Next, the mobile terminal 101 deletes all the attribute icons from the list image 402 of FIG. 4B displayed on the display unit 108 (timing T311). After that, the mobile terminal 101 determines whether or not the number of thumbnail images displayed at the timing T309 is larger than the standard number of displayed thumbnails. As a result of the determination, when the number of displayed thumbnail images determined is not larger than the standard number of displayed thumbnail images, the mobile terminal 101 performs the processing of the timing T314 described later. On the other hand, when the number of displayed thumbnail images determined as a result of the determination is larger than the standard number of displayed thumbnails, the mobile terminal 101 transmits the header information of the additional image and the additional data request notification requesting the thumbnail image to the digital camera 102 (timing). T312). Next, the mobile terminal 101 receives the header information and the thumbnail image of the additional image transmitted from the digital camera 102 in response to the additional data request notification (timing T313).

Next, the mobile terminal 101 displays a list of all the thumbnail images received at each of the timing T305 and the timing T313 on the display unit 108 (timing T314). Next, the mobile terminal 101 controls the display of the attribute icon according to the determination of the processing of the timing T310 (timing T315). At the timing T315, when it is decided to display the attribute icon in the processing of the timing T310, the mobile terminal 101 displays, for example, the attribute icons 404a to 404c associated with the thumbnail image 403 superimposed on the thumbnail image 403. To do. On the other hand, when it is determined not to display the attribute icon in the processing of the timing T310, the mobile terminal 101 has the attribute icons 404a to 404c associated with the thumbnail image 403 as shown in the list image 405 of FIG. 4C. Is not displayed. After that, the mobile terminal 101 ends this process.

Further, when the mobile terminal 101 receives the instruction to enlarge the thumbnail image (timing T316), the mobile terminal 101 determines the display size of the thumbnail image and the number of thumbnail images to be displayed according to the set enlargement width (timing T317). Next, the mobile terminal 101 determines the display specifications of the attribute icon, specifically, the display position of the attribute icon, based on the determined display size of the thumbnail image (timing T318). For example, a case where the number of determined thumbnail images to be displayed is one and the displayed thumbnail image is the thumbnail image 403 will be described. In this case, when the display size of the determined thumbnail image 403 is equal to or larger than the second size, the mobile terminal 101 collects all of the attribute icons 404a to 404c corresponding to the thumbnail image 403 in one place in the thumbnail image 403. Decide to display. The second size is the display size of the thumbnail image in which one thumbnail image is displayed in the list image. On the other hand, when the display size of the determined thumbnail image 403 is smaller than the second size, it is determined that the attribute icons 404a to 404c corresponding to the thumbnail image 403 are displayed at the standard positions, that is, at the four corners of the thumbnail image 403. ..

Next, the mobile terminal 101 deletes all the attribute icons from the list image 404 of FIG. 4B displayed on the display unit 108 (timing T319). Next, the mobile terminal 101 transmits a resizing data request notification requesting a resized (enlarged) thumbnail image (hereinafter, referred to as “resizing image”) to the digital camera 102 (timing T320). As a result, the digital camera 102 performs a resizing process in response to the received resizing data request notification to generate a resizing image, and transmits the resizing image to the mobile terminal 101. Here, when the mobile terminal 101 resizes the thumbnail image, the image quality is lower than when the digital camera 102 resizes the thumbnail image, and the thumbnail image becomes difficult to see. Therefore, in the present embodiment, the mobile terminal 101 acquires the resized image from the digital camera 102.

Next, the mobile terminal 101 receives the resized image from the digital camera 102 (timing T321) and displays the resized image on the display unit 108 (timing T322). Next, the mobile terminal 101 displays all the attribute icons associated with the resized image at the display position determined by the timing T318 (timing T323). For example, at the timing T323, the mobile terminal 101 collectively displays the attribute icons 404a to 404c at one end of the resized image 407 in which the thumbnail image 403 is resized, as shown in the list image 406 in FIG. 4D. After that, the mobile terminal 101 ends this process.

According to the process of FIG. 3 described above, the specifications for displaying the attribute icon are determined based on the display size of the thumbnail image. As a result, the attribute icon suitable for the display size of the thumbnail image can be displayed, and the thumbnail image can be easily viewed.

Further, in the process of FIG. 3 described above, the specifications for displaying the attribute icon are the specification for whether or not to display the attribute icon and the specification for the display position of the attribute icon. Thereby, in the list image, the balance of the attribute icon with respect to the thumbnail image can be adjusted, and thus the thumbnail image can be surely made easy to see.

Further, in the process of FIG. 3 described above, if the display size of the determined thumbnail image is smaller than the first size, the attribute icon is not displayed. As a result, it is possible to eliminate the situation where the thumbnail image becomes difficult to see as the display size of the thumbnail image becomes smaller.

In the process of FIG. 3 described above, when the determined display size of the thumbnail image is the second size or more, the attribute icons are collectively displayed in one place. Here, when the display size of the thumbnail image becomes large, the user may not be able to recognize at a glance the attribute icons arranged scattered like the four corners of the thumbnail image. Correspondingly, in the above-described embodiment, when the display size of the determined thumbnail image is the second size or larger, the attribute icons are displayed in one place, so that the user can see the attribute at a glance. The icon can be recognized.

Although the present invention has been described above with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments.

For example, the display size of the attribute icon when the display size of the thumbnail image is larger than the second size may be larger than the display size of the attribute icon when the display size of the thumbnail image is smaller than the second size. As a result, the user can easily recognize the attribute icon.

The present invention supplies a program that realizes one or more functions of the above-described embodiment to a system or device via a network or storage medium, and one or more processors in the computer of the system or device read the program. It can also be realized by the processing to be executed. The present invention can also be realized by a circuit (for example, ASIC) that realizes one or more functions.
