Claim One:
1. A fundus camera comprising: an illumination unit configured to illuminate an ocular fundus of a subject's eye; an autofluorescent exciter filter configured to be insertable into and retractable from an illumination optical path of the illumination unit; an observation and photographing unit configured to receive reflection light from the ocular fundus illuminated by the illumination unit and form an ocular fundus image; an autofluorescent barrier filter configured to be insertable into and retractable from an observation and photographing optical path of the observation and photographing unit; an image capturing unit configured to capture an ocular fundus image formed by the observation and photographing unit; and a calculation unit configured to calculate image data from the image capturing unit; wherein the calculation unit of the fundus camera which can perform both of color image photographing and photofluorography, converts the ocular fundus image which is illuminated using the autofluorescent exciter filter inserted into the illumination unit 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.
