when the number of similar medical images moved from the second display region to the first display region is equal to or smaller than the prescribed number, the moved similar medical image is displayed in the first display region and the third display region, and

when the number of similar medical images moved from the second display region to the first display region exceeds the prescribed number, the similar medical image included in the first display region is moved to the third display region.

6. The control method according to claim 4, wherein

a display size of a similar medical image in the third display region is set smaller than a display size of a similar medical image in the first display region and the second display region.

7. The control method according to claim 1, wherein

a display arrangement of the second display screen is the same as a display arrangement of a first display region that is included in the first display screen.

8. The control method according to claim 1, wherein

the display includes a first display and a second display, and

the first display screen is displayed on the first display and the second display screen is displayed on the second display.

9. The control method according to claim 1, wherein

disease name information on a lesion represented in a medical image that is a diagnostic interpretation object is not set in additional information of the medical image, and disease name information on a lesion represented in each of the plurality of received similar medical images is set in additional information of each of the plurality of received similar medical images.

10. The control method according to claim 1, wherein

the second display region includes a prescribed number of display frames, and

images of the prescribed number or less among the plurality of received similar medical images are displayed in each of the display frames in a descending order of degrees of similarity with the medical image that is a diagnostic interpretation object.

11. The control method according to claim 1, wherein

the control method causes the computer of the information terminal to:

transmit information indicating the feature quantity of the region of interest to the case retrieval system; and

receive the similar medical image having the prescribed degree of similarity with the feature quantity of the region of interest from the case retrieval system.

12. The control method according to claim 1, wherein

the control method causes the computer of the information terminal to:

transmit the one medical image that is a diagnostic interpretation object and specification information indicating the region of interest to the case retrieval system; and
