| Zusammenfassung: | To provide an ophthalmologic apparatus capable of realizing high accuracy of focusing by acquiring a more correct defocus amount.SOLUTION: An ophthalmologic apparatus comprises: first acquisition means which acquires a first defocus amount related to the eyeground by a first system; second acquisition means which acquires a second defocus amount related to the eyeground by a phase difference system different from the first system; and control means which drives a focus lens based on the first defocus amount, the second defocus amount, and a threshold of a defocus amount related to the eyeground.SELECTED DRAWING: Figure 5
【課題】より正しいデフォーカス量を取得して、高いフォーカス精度を実現できる眼科装置を提供する。【解決手段】第１の方式により眼底に関する第１のデフォーカス量を取得する第１の取得手段と、第１の方式とは異なる位相差方式により眼底に関する第２のデフォーカス量を取得する第２の取得手段と、第１のデフォーカス量、第２のデフォーカス量、および眼底に関するデフォーカス量の閾値に基づいてフォーカスレンズを駆動する制御手段と、を眼科装置に配する。【選択図】 図５ |
