<P>PROBLEM TO BE SOLVED: To solve positional deviation of the same section between respective spectrum images even in occurrence of change in the alignment of the eye and an apparatus due to time change. <P>SOLUTION: This spectrum ocular fundus image data measuring apparatus is provided with: an illumination optical system 10 for illuminating the ocular fundus F of the eye to be examined E; a light-receiving optical system 20 which receives a reflected beam from the illuminated eye fundus F for forming an eye fundus image on the light-receiving surface of an imaging part 4; and a data measurement part 7 which compares a plurality of pieces of ocular fundus image original data obtained at different times based on a signal from the light-receiving surface with each other and carries out positional correction of the image for generating a series of ocular fundus image data to which positional correction is carried out. In a desirable mode, the data measurement part 7 compares the pieces of ocular fundus image original data different for variation which is not larger than a threshold with each other and carries out the positional correction of the image for generating the series of spectrum ocular fundus image data in a prescribed wavelength range. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
