ABSTRACT:
An area having a diameter in which a peripheral area of an eye fundus image is covered with a mask is displayed on a monitor. When a region which may be abnormal is found in the vicinity of a boundary between the mask and the eye fundus image during image viewing, the display area enlarging means is operated. Then, an aperture area of the mask is enlarged to expand a display area of the eye fundus image, so the eye fundus image including some flare is displayed on a wide area. Therefore, an abnormal state of the region can be recognized.
