PROBLEM TO BE SOLVED: To reduce a burden on an examiner and a subject by improving imaging efficiency by maintaining highly accurate ocular fundus tracking regardless of an imaging state and an imaging method.SOLUTION: An ocular fundus imaging apparatus includes: an OCT optical system for irradiating an eye to be examined with OCT measurement light, receiving interference light between OCT return light from the eye to be examined and reference light, and acquiring a tomographic image； an SLO optical system for irradiating the eye to be examined with SLO measurement light, receiving SLO return light from the eye to be examined, and acquiring a plane image； detection means for detecting a movement of the eye to be examined by using a plane image as a reference and a plane image as a comparison object； correction means for correcting an irradiation position of the OCT measurement light on the basis of the detected movement； and update means for updating the plane image as a reference when the detection means detects the movement according to an imaging state of the plane image by the SLO optical system.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】 撮影状態や撮影方法によらず高精度な眼底追尾を維持することにより、撮影効率向上によって検者および被験者の負担を軽減させる。【解決手段】 ＯＣＴ測定光を被検眼に照射し、前記被検眼からのＯＣＴ戻り光と参照光との干渉光を受光して断層画像を取得するＯＣＴ光学系と、ＳＬＯ測定光を前記被検眼に照射し、前記被検眼からのＳＬＯ戻り光を受光して平面画像を取得するＳＬＯ光学系と、基準となる平面画像と比較対象の平面画像を用いて、前記被検眼の動きを検出する検出手段と、前記検出された動きに基づいて、前記ＯＣＴ測定光の照射位置を補正する補正手段と、前記検出手段が動きを検出するときの基準となる平面画像を、前記ＳＬＯ光学系による平面画像の撮影状態に応じて更新する更新手段とを有する。【選択図】 図１
