Abstract
A glaucoma diagnosis apparatus capable of minimizing the difficulty of early glaucoma diagnosis caused by the illumination irregularities of the fundus is provided. For each part of the fundus image FB photographed by a color fundus camera Q, the G-component image data corresponding to the G-component reflected light intensity or the B-component image data corresponding to the B-component reflected light intensity is divided by the sum of the G-component image data, the B-component image data and also the R-component image data corresponding to the R-component reflected light intensity, reflected light intensity ratio data is obtained. Based on this reflected light intensity ratio data, the fundus image is reconstructed for glaucoma diagnosis.
