PROBLEM TO BE SOLVED: To provide a mechanism to execute tracking based on the movement of an eye to be examined at high speed while maintaining optimum fixation of the eye to be examined in an ophthalmic imaging apparatus in which scanning means is used for imaging means and fixation target presentation means in common.SOLUTION: An ophthalmic imaging apparatus includes an SLO optical system for imaging an eyeground Er of an eye E to be examined using SLO scanning means 104 and acquiring an SLO image, a fixation target optical system for presenting a fixation target to the eyeground Er using the common SLO scanning means 104, and an OCT optical system for imaging an imaging region set in a preview imaging range (a first imaging range) imaged by the SLO optical system, and acquiring an OCT image. The ophthalmic imaging apparatus sets a partial imaging range which includes a fixation target presentation region and is narrower than the first imaging range as a second imaging range which is a range for the SLO optical system to image the eyeground Er in the imaging by the OCT optical system, and corrects a position in the eyeground Er of the imaging region imaged by the OCT optical system using the SLO image acquired by the imaging of the second imaging range by the SLO optical system.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】撮像手段と固視標提示手段との走査手段が共通である眼科撮像装置において、好適な被検眼の固視を維持しつつ被検眼の動きに基づくトラッキングを高速に行える仕組みを提供する。【解決手段】SLO走査手段104を用いて被検眼Eの眼底Erを撮像してSLO画像を取得するSLO光学系と、共通のSLO走査手段104を用いて眼底Erに対して固視標を提示する固視標光学系と、SLO光学系で撮像するプレビュー撮像範囲(第1の撮像範囲)内に設定された撮像領域を撮像してOCT画像を取得するOCT光学系を備え、OCT光学系の撮像の際にSLO光学系が眼底Erを撮像する範囲である第2の撮像範囲として、固視標の提示領域を含み且つ第1の撮像範囲よりも狭い部分撮像範囲を設定し、SLO光学系で第2の撮像範囲を撮像することにより得られたSLO画像を用いて、OCT光学系で撮像する撮像領域の眼底Erにおける位置を補正する。【選択図】図2
