Therefore, one identification information on the list 40 is associated with a series of images grouped together as the same series.
By confirming the identification information (series description) in the list 40, the user can recognize which inspection series image is used.
In the list 40, other information such as the number of images included in each series image may be displayed together with the identification information.

Returning to FIG. 3, next, the control unit 21 determines whether or not the selection operation of one identification information has been performed from the list 40 (step S6), and if the selection operation is not performed (step S6: NO), The process of step S6 is repeated.
On the other hand, when the selection operation is performed (step S6: YES), the control unit 21 acquires the image data and incidental information of the series image corresponding to the selected identification information from the image management server 10 (step S7), and acquires the image data. The image and incidental information displayed in the image display area 30 are switched according to the image data and incidental information of the series image (step S8).

FIG. 6 shows an example of a state in which the image displayed in FIG. 5 is switched to a series image.
FIG. 6 shows a series image displayed when the top identification information in the list 40 is selected in FIG. 5 and incidental information thereof.

Further, as shown in FIG. 6, the series image is displayed as a pattern in which a plurality of images are overlapped, whereby the user can easily recognize that the images are overlapped. The mode in which the series image is displayed is not limited to this, and may be displayed with a pattern of only one image.

Next, the control unit 21 determines whether or not an operation signal of a predetermined operation for switching the series image on the image display area 30 is detected via the operation unit 22 (step S9), and the operation signal is generated. If it is not detected (step S9: NO), the process of step S9 is repeated.
On the other hand, when the operation signal is detected (step S9: YES), the series image is switched (step S10), and this process ends.
Here, the predetermined operation is, for example, a key-down operation using a keyboard while the cursor is in the image display area 30.

In the display control process of FIG. 3 described above, when the operation signal for switching the series image is not detected (step S9: NO), the process of step S9 is repeated, but this operation signal is not detected. In the case (step S9: NO), it may be possible to move to step S6 and determine whether or not the selection operation of one identification information has been performed from the list 40.
