摘要

An eye fundus image photographing device and method that can acquire images of higher quality. The eye fundus image photographing device photographs a wide-angle eye fundus image on an appropriate exposure condition with respect to a peripheral area different from an optic disk region of an eye fundus area and detects the optic disk region from the wide-angle eye fundus image. Moreover, based on the detection result of the optic disk region, the eye fundus image photographing device photographs a narrow-angle eye fundus image which assumes an area of the optic disk region as an object, on an appropriate exposure condition with respect to the area of the optic disk region. Further, the eye fundus image photographing device generates a synthetic eye fundus image of a high dynamic range by synthesizing the wide-angle eye fundus image and the narrow-angle eye fundus image.
