摘要:
PROBLEM TO BE SOLVED: To provide a fundus camera capable of obtaining a fundus image in which the effect of unevenness of the light projected onto a fundus oculus is suppressed regardless of the optical characteristics of the subject eye.SOLUTION: The fundus camera comprises: an illumination optical system for projecting the light from a light source onto the fundus oculus of a subject eye and a fundus oculus observation and imaging optical system for receiving the light which is the light from the light source reflected off the fundus oculus, the fundus camera capturing a fundus image of the subject eye on the basis of light receiving results of image pickup devices. In addition, a control unit performs: a step S1 of obtaining information which indicates the size of a range the fundus oculus over which the light from the illumination optical system is projected a step S3 of obtaining a distribution of unevenness of the light on the fundus oculus, the light being projected from the illumination optical system, on the basis of the information obtained in the step S1 and a step S7 of correcting the brightness of the fundus image, using the obtained distribution of unevenness of the light.
