PROBLEM TO BE SOLVED: To easily perform auto-focus control during a visible light observation and auto-focus control during a near-infrared light observation.SOLUTION: While focusing means, which focuses an image of the fundus oculi of a subject eye on imaging means that has sensitivity to visible light and infrared light, is moved along an optical path with an infrared cut filter inserted into the optical path, an ophthalmologic apparatus obtains the contrast of an image in a focus detection range for the fundus oculi at different positions of the focusing means in the optical path.COPYRIGHT: (C)2014,JPO&INPIT【課題】 可視光観察時の自動合焦制御と近赤外光観察時の自動合焦制御とをそれぞれ簡易に行うこと。【解決手段】 眼科装置が、赤外カットフィルタが光路内に挿入されている状態で、可視光及び赤外光に感度を有する撮像手段に被検眼の眼底の像を合焦する合焦手段を光路に沿って移動させながら、前記光路における前記合焦手段の異なる位置で前記眼底の合焦検出範囲における画像のコントラストを取得する。【選択図】 図1
