PROBLEM TO BE SOLVED: To measure the three-dimensional shape of an eyeground from an eyeground stereo image with precision by creating spectral images with different wavelengths from the inputted eyeground stereo image, obtaining depth information of the eyeground on the basis of the spectral images. SOLUTION: First, an eyeground stereo photograph is read by an image reading device 7. The rear photograph is converted into digital image data and inputted as a stereo image file in an arithmetic analyzing part 2. The digitized stereo image data are dissolved into color information of the three primary colors of light, R(red), G(green) and B(blue), recognized as the sets of pixels obtained by digitizing the density values of individual points and stored in a memory in the arithmetic analyzing part 2 as RGB density information. An operator indicates the part 2 to execute a program for measuring the three-dimensional shape of the eyeground by operating an indication input part 3. The part measures the three-dimensional shape of the eyeground from the eyeground stereo image.
