Patent ID: 7658494

Claim:
A fundus camera comprising: an illumination optical system comprising a visible light source, for illuminating a fundus of an examinee's eye with visible light from the light source; an image-pickup optical system comprising an image-pickup element, for photo-receiving reflection light from the fundus illuminated by the illumination optical system and picking up an image of the fundus; a mode selection switch with which switching between a fundus photographing mode of picking up a normal color fundus image and a retinal function measurement mode of measuring a retinal function of the eye based on variance of an intrinsic signal of a retina of the eye made by retinal stimulation is performed; and a control unit arranged to control the illumination optical system and the image-pickup optical system, wherein the control unit lowers, when the retinal function measurement mode is selected, illumination intensity of the illumination optical system per unit time in illuminating the fundus by the illumination optical system than illumination intensity per unit time in picking up the color fundus image, and controls the image-pickup element to pick up a first visible fundus image and a second visible fundus image which are picked up at different points in time.
