ABSTRACT:
To provide a spectroscopic fundus measuring apparatus capable of identifying each part in spectral fundus images easily and accurately based on its spectral characteristic and a measuring method therefor. A spectral fundus image measuring apparatus1of the present invention includes: an illumination optical system10;a light receiving optical system20for photographing a series of spectral fundus images of different wavelengths; an image processing section7for processing the spectral fundus images; a storage section7A; and a display section7B. The image processing section7has a position correcting section72for correcting the series of spectral fundus images to match the positions of the same parts therein, and an image analyzing section73for calculating the spectral characteristic of each part in the spectral fundus images based on the series of spectral fundus images corrected in the position correcting section72.The storage section7A stores the spectral characteristics of the parts together with standard spectral characteristics of specific parts. The image processing section7has a first grouping section74A for comparing the spectral characteristic of each part with the standard spectral characteristics of the specific parts to divide the parts into groups corresponding to the specific parts.
