A display control unit (23) scrolls and displays, in a specific display region within a screen, a plurality of images to be displayed. An operation-receiving unit (21) receives scroll switching instructions and display mode switching instructions resulting from operations performed by a user. When the display mode is to be switched, the display control unit (23) switches the display within the display region in such a way that, of the plurality of images displayed in a first display mode in the display region, at least one image, in a position that will be the first to leave the display region when scrolling occurs in the direction of travel, is also disposed in a position that will be the first to leave the display region when scrolling occurs in the direction of travel within the display region when the display mode has been switched to a second display mode.
