A fundus image observation program is provided which can reduce a burden on an examiner upon checking images obtained through a fluorescent imaging procedure. A computer 1 acquires in advance at least one first fluorescent angiographic image photographed on the basis of a first photographing trigger signal, and at least one second fluorescent angiographic image photographed on the basis of a second photographing trigger signal whose output timing is different from the first photographing trigger signal, as one set of image group data in a memory 71 in a fluorescent imaging procedure for an examinees eye. A fluorescent angiographic image photographed at any angiography timing is selectively displayed on a monitor 80 from the first and second fluorescent angiographic images included in the image group data on the basis of the image group data.
