<P>PROBLEM TO BE SOLVED: To provide a device for analysis of crystalline lens image that can objectively and automatically perform evaluation of an Emery-Little classification for cataract diagnosis. <P>SOLUTION: The device for analysis of crystalline lens image includes: an image acquiring means 200 for acquiring optical cutting-plane image data obtained by taking an image of a subject's eye; a crystalline lens extraction means 201 for extracting a crystalline lens region by image processing from the optical cutting-plane image data; a specified region setting means 202 for setting a specified region, which has an area smaller than that of the crystalline lens region and which at least partially includes an embryonic nucleus region, inside the crystalline lens region; a representative color data computing means 203 for computing representative color data representing colors in the specified region, on the basis of pixel data constituting the specified region; a color data storage means 204 in which color data for comparison, having a grade of the Emery-Little classification known, is prestored; and a grade determination means 205 for determining the grade of the subject's eye by comparing and computing the known color data for comparison and the computed representative color data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
