PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of implementing accurate working distance matching without adding another optical system for projecting an index.SOLUTION: A fundus camera 1 as an ophthalmologic apparatus includes: a fundus camera optical system 79 capable of imaging a subject eye 28 index projection means for projecting an index used for working distance matching between the subject eye 28 and fundus camera optical system 79, on the subject eye 28 and working distance determination means for determining whether a working distance is appropriate or not from reflection images L5, L6 of the index projected on an imaged picture of the subject eye 28. The index projection means projects the index including a bright part and a dark part whose brightness is lower than that of the bright part, to the subject eye 28. The working distance determination means determines whether the working distance is appropriate or not by using contrast information on the reflection images L5, L6 of the index.COPYRIGHT: (C)2015,JPO&INPIT【課題】指標の投影のための別個の光学系を追加することなく、正確な作動距離合わせが実現できる眼科装置を提供する。【解決手段】眼科装置としての眼底カメラ1は、被検眼28を撮像できる眼底カメラ光学系79と、被検眼28と眼底カメラ光学系79との作動距離合わせのための指標を被検眼28に投影する指標投影手段と、撮像した被検眼28の画像に映り込んでいる指標の反射像L5、L6から作動距離が適正か否かを判定する作動距離判定手段とを有し、指標投影手段は、明部と明部よりも輝度が低い暗部とを含む指標を被検眼28に投影し、作動距離判定手段は、指標の反射像L5、L6のコントラスト情報を用いて、作動距離が適正か否かを判定する。【選択図】図1
