< Topic >When the automatic alignment and eyeground tracking is done according to the movement of suffering eye exasmination, the fault image where the deformation is little is acquired. SolutionsBeing the optical interference fault image pickup device which acquires the fault image of suffering eye exasmination on the basis of the interference light which interferes with the reflected light from the suffering eye exasmination where the measuring beam was irradiated and the reference beam which corresponds to the measuring beam, when you acquire the control section and the multiple fault images inside the portable section and the scan section at least controls one side on the basis of the multiple images of the suffering eye exasmination which you acquire in the time when it differs from the portable section which moves the optical system which includes the optical path of the measuring beam and the scan section which scans the measuring beam with suffering eye exasmination, of the position which where suffering eye exasmination differs, the portable sectionWith the halt section which the scan section inside at least halts the control of one side it has. < Choice figure > Drawing 9【課題】被検眼の動きに応じて自動アライメントや眼底トラッキングを行う場合であっても、歪みの少ない断層画像を取得する。【解決手段】測定光が照射された被検眼からの戻り光と、測定光に対応する参照光とを干渉させた干渉光に基づいて、被検眼の断層画像を取得する光干渉断層撮像装置であって、測定光の光路を含む光学系を移動する移動部と、測定光を被検眼で走査する走査部と、異なる時間に取得した被検眼の複数の画像に基づいて、移動部と走査部とのうち少なくとも一方を制御する制御部と、被検眼の異なる位置の複数の断層画像を取得する場合に、移動部と走査部とのうち少なくとも一方の制御を停止する停止部とを備える。【選択図】 図9
