A report-data collecting unit retrieves and collects a character string in accordance with the prescribed character-string retrieval condition and the character string of annotation data. An image data display unit displays the character string and a list showing a medical image referred to while the object is being photographed. When the user selects the character string by designating the medical image shown in the list, both the character string and the medical image are associated by an image-data acquisition/process unit and then pasted at a prescribed position in a medical-image reading report preparation screen. Further, the data representing the medical image thus pasted is archived in an image database.
