PROBLEM TO BE SOLVED: To realize an eyeball image pickup device that photographs an eyeball in an excellent way regardless of a simple device configuration. SOLUTION: A light source 14 emits a light with a wavelength including a visual sensitivity band and an invisible light wavelength band. A camera 11 photographs only a reflected image of a light of the wavelength band of the invisible light based on a characteristic of a camera filter 20. A lighting filter section 21 consisting of plural filters with a different transmission characteristic of the respective wavelength band is placed to a front side of the light source 14. The wavelength band of a light emitted from the light source 14 to an eyeball 10 is changed by using selectively any of plural filters of the lighting filter section 21 so as to change a size of a pupil 17. |
