EYEGROUND OBSERVING DEVICE, EYEGROUND IMAGE PROCESSING DEVICE, AND PROGRAM

摘要

A fundus oculi observation device 1 has a function of forming a tomographic image of a fundus oculi Ef and a function of capturing a two-dimensional image of the surface of the fundus oculi Ef (a fundus oculi image Ef'). An arithmetic and control unit 200: specifies a vascular region in the tomographic image and a vascular region in the fundus oculi image Ef'; obtains a common region of the vascular region in the tomographic image and the vascular region in the fundus oculi image Ef' and specifies the common region in the tomographic image; erases an image of the common region from the tomographic image and estimates a layer position within the common region to add an image representing this layer position to the common region; and obtains the layer thickness of the fundus oculi Ef in the common region based on the image representing this layer position.
