    • PROBLEM TO BE SOLVED: To provide a fundus camera which can be inexpensively manufactured and enables a high quality image of a fundus to be captured. SOLUTION: The fundus camera is provided for observing an eyeball 11 and includes an irradiation device (1) for irradiating the imaging area of an fundus oculi (12) with light and an image capturing device (14) capable of forming an image of the imaging area of the fundus oculi (12) by an image forming device (10). The irradiation focus and the image capturing focus are disposed confocal. The irradiation device (1) further includes a shift means (21) for irradiating the image capturing area of the fundus oculi 12 with a periodic light pattern (12) and shifting the light pattern by an amount shorter than one period and an evaluation device (22) for jointing at least three images captured by the image capturing device (14) and irradiated with light patterns shifted from one another into one image.
