摘要:
A fundus camera includes an illumination unit to illuminate an ocular fundus of a subject's eye, an autofluorescent exciter filter insertable into and retractable from an illumination optical path of the illumination unit, an observation and photographing unit to receive reflection light from the ocular fundus illuminated by the illumination unit and form an ocular fundus image, an autofluorescent barrier filter insertable into and retractable from an observation and photographing optical path, an image capturing unit to capture an ocular fundus image, and a calculation unit to calculate image data, wherein the calculation unit converts the ocular fundus image which is illuminated using the autofluorescent exciter filter and captured by a color image capturing unit as a color image, in a state that no autofluorescent barrier filter is inserted into the observation and photographing unit, into a monochromatic image from specific color data of each of the pixels.
