PROBLEM TO BE SOLVED: To present an image for supporting a proper diagnosis, by enabling easy performance of comparative observation of a plurality of moving images taken in a plurality of photographing ranges of fundus oculi.SOLUTION: An image display device acquires a plurality of moving images which are obtained by photographing a plurality of photographing ranges of fundus oculi, and a wide view angle image which is obtained by photographing ranges, including the plurality of photographing ranges, of the fundus oculi. In this case, the plurality of moving images are associated with time phase data based on a biological signal acquired when each of the ranges is photographed. The image display device displays at least one frame of each of the plurality of moving images in a superimposed state in a position which is determined on the basis of information on positions of the plurality of photographing ranges on the wide view angle image. In this superimposed display, the image display device displays the plurality of moving images in display timing synchronized on the basis of the time phase data. |
