Based on an examination report of an endoscopic examination designated, an attached image extraction unit reads image identification information, which identifies an examination image attached to the examination report. Based on the image identification information, the attached image extraction unit extracts the examination image (that is, an attached image) attached to the examination report, from examination images corresponding to the designated endoscopic examination. The examination images are read from an image folder of an image database (DB). A screen display controller performs control to display the extracted attached image on a display screen.
