发明名称 Characteristic image extraction method and ophthalmologic apparatus
摘要 Provided is an ophthalmologic apparatus for detecting an eye movement from movements of a plurality of characteristic points within a fundus image. It is determined whether or not the plurality of characteristic points are included in a new fundus image when a position of a fixation index is changed, based on a relationship between a displacement amount of the fixation index and positions of the characteristic points within a fundus plane. If it is determined that at least one of the plurality of characteristic points is not included in the new fundus image, new characteristic points are extracted from a limited range within a new fundus plane image. Accordingly, the characteristic points can be efficiently reacquired for eye movement detection performed when an imaging target region of an eye to be inspected is changed by the fixation index.
