ABSTRACT:
Highly reliable technology is provided with the capable of forming three-dimensional images of fundus oculi. The image forming part220of a computational control unit200forms images of the surface of fundus oculi Ef based on results of detecting fundus oculi catoptric light of light illuminated by a fundus camera unit1A, in addition to forming tomographic images of the fundus oculi Ef based on results of detecting interference light LC from the OCT unit150. The controlling part210synchronizes the timing of detecting fundus oculi catoptric light of light illuminated by the fundus camera unit1A with the timing of detecting interference light LC from the OCT unit150. The correction processing part240corrects the image positions of the tomographic images based on results of detecting interference light LC from the OCT unit150on the basis of two-dimensional images based on the results of detecting fundus oculi catoptric light of light illuminated from the fundus camera unit1A. The image processing part230forms three-dimensional images of fundus oculi Ef based on tomographic images for which the image positions have been corrected.
