摘要： PROBLEM TO BE SOLVED: To prepare a synthetic eyeground image in a short time by inputting information on a plurality of eyeground images of different glances of the same subject extracting feature points of each eyeground image, taking a correlation of surrounding areas of the feature points, making areas with high correlation coincident between each image and assembling a synthetic eyeground image. SOLUTION: Eyeground images of different glances of a subject are photographed by an eyeground camera and plural sheets of obtained input images 201 are stored in an image storing part 207 through a control part 203. The positional relation of each eyeground image is recognized by the control part 203 and is stored in a data storing part 208. Next, in a feature extracting part 204, each eyeground image is binarized, a blood vessel image is extracted, the blood vessel image is thinned and an intersecting point of the blood vessel is determined. By determining a correlation for one intersecting point of the blood vessel on the eyeground image and the surrounding region with all the intersecting points on the eyeground images to be overlapped objects as a center, finding out an intersecting point pair having a maximum correlation value and making the locations of the intersecting point pair coincide each other, two sheets of eyeground images are synthesized.
