PROBLEM TO BE SOLVED: To allow an examiner to easily check to what extent a positional deviation has occurred in a display form (e.g., a measurement line) before and after a position correction of the display form displayed in a front image of an eye to be examined in order to set a tomographic image acquisition position in correcting the tomographic image acquisition position for the eye to be examined based on the positional deviation of the eye to be examined.SOLUTION: An ophthalmologic imaging device includes: display control means for causing a first display form indicating a tomographic image acquisition position for an eye to be examined to be displayed in a front image of the eye to be examined, and causing it to be moved according to an operation by an examiner; and correction means for correcting the tomographic image acquisition position in the eye to be examined based on a positional deviation of the eye to be examined, and, in a state that the first display form is displayed at a position in the front image, which is moved according to the operation by the examiner, correcting a position of a second display form displayed in the front image based on the positional deviation of the eye to be examined from the position of the first display form. The display control means moves the first display form to the position of the second display form according to the operation by the examiner.SELECTED DRAWING: Figure 6 【課題】 被検眼の位置ずれに基づいて被検眼の断層画像の取得位置を補正する際に、検者が、断層画像の取得位置を設定するために被検眼の正面画像に表示された表示形態（例えば、測定ライン）の位置補正の前後で、該表示形態がどの程度位置ずれしたのかを容易に確認できることである。【解決手段】 眼科撮影装置は、被検眼の断層画像の取得位置を示す第１の表示形態を、被検眼の正面画像に表示させ、検者の操作に応じて移動させる表示制御手段と、被検眼の位置ずれに基づいて被検眼における断層画像の取得位置を補正し、第１の表示形態が検者の操作に応じて移動された正面画像上の位置に表示された状態で、被検眼の位置ずれに基づいて正面画像に表示された第２の表示形態の位置を第１の表示形態の位置から補正する補正手段と、を備え、表示制御手段は、検者の操作に応じて、第１の表示形態を第２の表示形態の位置に移動させる。【選択図】 図６
