A first display displays a medical image based on medical image data. A second display displays a generation screen for generating a string of a medical imaging report. A display controller causes the first display and the second display to display images. An operation part is for operating a pointer displayed on the first display and the second display. An annotation generator receives designation of a position on the medical image displayed on the first display by using the pointer, and attaches sign data representing a position specification sign to the medical image data. An address information acquiring part acquires address information for reading out the medical image data to which the sign data is attached. A linking part links the address information to a link object such as a string designated by using the pointer and displayed on the generation screen displayed on the second display.
